Will virtual primary care become a new model of healthcare delivery?

Will virtual primary care become a new model of healthcare delivery? | healthcare technology | Scoop.it

The pandemic drove many patients to their primary care docs via video. And it worked.

 

A telehealth expert (Dr. Peter Antall) explains how this shift could become a permanent hybrid with in-person care in an Interview with healthcareITNews

 

Here is a summary from the interview.

 

What is Virtual Primary Care

Virtual primary care is allowing patients to see their primary care physician in person or virtually, depending on their needs.

 

It combines the convenience of telehealth with the ability to strengthen recurring relationships with primary care physicians. It also can help provide a medical home for patients who have no primary care physician, either due to lack of access or lack of engagement.

 

The emergence of virtual primary care stems from the recognition that the traditional primary care model doesn't work well for many patients.

 

Access to care remains a major issue for many patients, due to geographical constraints and a growing shortage of primary care physicians, which has only been exacerbated by the pandemic.

 

Do Patients Want it?

Patients are receptive. A recent Amwell survey shows consumers want a virtual approach to primary care –

  • Most consumers (77%) would prefer to see their existing primary care provider via video.
  • 25% of consumers are willing to switch providers to get it.
  • 80% saying they would prefer to see the same primary care physician regularly via virtual care.

 

Can virtual primary care provide a simple, seamless care experience? How are patients supported throughout the care process?

 

The best virtual primary care programs are well coordinated and enable a seamless care experience with the ability to transition patients between in-person and virtual care settings, and to various specialties or allied care providers as needed.

 

In this way the care is holistic and the patient journey is clear and simple.

 

Data sharing is an important part of creating a highly coordinated and seamless care experience. Records from all visits should be available to all providers on the telehealth platform across specialties and should be shared with the primary care physician in brick and mortar if one exists. This interoperability improves care and improves the referral and transition process.

 

To ensure patients are supported, virtual primary care programs should include care coordination capabilities.  For example, secure messaging between patients, healthcare professionals and administrative staff can help patients receive quick answers to their questions and ensure that all of their needs are met in a timely fashion, even after a visit has finished.

 

 

Can virtual primary care help with population health?

 

The flexibility of remote access makes it possible for providers to see patients' living conditions, evaluate social determinants of health, and respond in ways that make a deep impact on patients' lives.

 

Providers also can leverage virtual primary care to evaluate medication adherence among patients with diabetes, hypertension and high cholesterol. When breakdowns in medication adherence are discovered, providers and support staff can work to engage patients in following their treatment plan more closely. This avoids complications that can occur when patients deviate from recommended treatment.

 

Improvements in compliance and ongoing care can be accomplished through use of frequent brief touchpoints, care coordination, nudges and team-based care. Prompts and reminders can be used to reinforce the care plan.

 

With capabilities such as these, virtual primary care positions providers and health plans not only to improve population health, but also to perform well under value-based models of care.

 

More and more, it's clear that the future of care depends on hybrid models of care delivery such as this and I believe we've only just begun to scratch the surface of what's possible with virtual primary care and how it contributes to the continued transformation of healthcare.

nrip's insight:

As we learn to live the after effects of the pandemic, even the skeptics have started agreeing  that the future of care depends on hybrid models. A healthy mix of physical and tele(read virtual/remote) will be adopted - even by unwilling care providers as the consumers have clearly got a taste for it and liked it. And once we accept the hybrid model opening the doors for a accepted technology driven care process (unlike EHR's in 2010), the doors may widely open up further to allow Algorithmic analysis tools, screeners, diagostics to further add flavor to this mix.

Effectiveness of ML Approaches for Predicting Gastrointestinal Bleeds in Patients Receiving Antithrombotic Treatment

Effectiveness of ML Approaches for Predicting Gastrointestinal Bleeds in Patients Receiving Antithrombotic Treatment | healthcare technology | Scoop.it

Anticipating the risk of gastrointestinal bleeding (GIB) when initiating antithrombotic treatment (oral antiplatelets or anticoagulants) is limited by existing risk prediction models. Machine learning algorithms may result in superior predictive models to aid in clinical decision-making.

 

Objective: To compare the performance of 3 machine learning approaches with the commonly used HAS-BLED (hypertension, abnormal kidney and liver function, stroke, bleeding, labile international normalized ratio, older age, and drug or alcohol use) risk score in predicting antithrombotic-related GIB.

 

Design, setting, and participants: This retrospective cross-sectional study used data from the OptumLabs Data Warehouse, which contains medical and pharmacy claims on privately insured patients and Medicare Advantage enrollees in the US. The study cohort included patients 18 years or older with a history of atrial fibrillation, ischemic heart disease, or venous thromboembolism who were prescribed oral anticoagulant and/or thienopyridine antiplatelet agents between January 1, 2016, and December 31, 2019.

 

In this cross-sectional study, the machine learning models examined showed similar performance in identifying patients at high risk for GIB after being prescribed antithrombotic agents. Two models (RegCox and XGBoost) performed modestly better than the HAS-BLED score. A prospective evaluation of the RegCox model compared with HAS-BLED may provide a better understanding of the clinical impact of improved performance.

Lab-Grown Mini-Hearts Mimic 25-Day-Old Human Embryo's Heart

Lab-Grown Mini-Hearts Mimic 25-Day-Old Human Embryo's Heart | healthcare technology | Scoop.it

A team of researchers has developed the first human "mini-hearts" in the lab to have clearly beating chambers. The miniature organs, or organoids, are no bigger than sesame seeds and were generated by self-assembly using pluripotent stem cells, according to Science Magazine.

 

The organoids mimic the functioning heart of a 25-day-old human embryo, and they may help humans solve the heart's many mysteries.

 

Our capability to model the complexity of the human heart in vitro is still limited, consequently limiting our knowledge of how heart diseases develop.

 

Congenital heart defects, for example, are the most common birth condition in humans, affecting around 1 percent of all live births. This alone demonstrates the need to create more precise organ-like platforms, which is where the researchers come in, with their newly devised method which was described in a study published in the journal Cell.

 

The researchers engineered human pluripotent stem cells, which can divide into any kind of tissue, into multiple forms of cardiac cells to create heart organoids whose cells self-organize like those in an embryo. The aim was to create three tissue layers that make up a heart chamber's walls, which are one of the first parts of the heart to form.

 

The organoids, which are around 2 mm in diameter and have survived more than 3 months in the lab so far, become structurally equal to the heart of a 25-year-old embryo in a week. They only have one chamber and the main types of cells at this point of development. Moreover, the heart's clearly defined chamber beats 60 to 100 times a minute, much like the heart of an embryo at the same age.

State of Interoperability today and what to expect in the future

State of Interoperability today and what to expect in the future | healthcare technology | Scoop.it

The linked interview gives us all in Healthcare Technology  a lot of food for thought. This below is a set of points extracted and massaged with my viewpoints

 

The biggest barrier to physicians having the most complete medical history for their patients at every point of patient care is the lack of interoperability among information systems.

 

State of Interoperability today:

 

The industry has made progress in developing open standards and application programming interfaces to facilitate data fluidity and sharing among multiple electronic health record systems and data repositories. As a result, commercial and open source interoperability services are coming online. While there is room for optimism, the industry is still grappling with data structure and management challenges

.

First, incomplete, disparate and disconnected data.

Most health and patient data is stored as unstructured medical format, and identifying information in the data is a manual and time-consuming process. There are significant variations in the way data is shared, read and understood across health systems, which can result in information being siloed and overlooked or misinterpreted

.

Further, most EHR systems do not follow patients on their care journey beyond the hospital or clinic walls. As a result, only a portion of healthcare data is available at any point of care, resulting in a fragmented view of a patient's health history.

 

 

Second, slow adoption and scaling of open interoperability standards.

Standards can streamline the structured data exchange needed to improve preventive and value-based care for people, predictions, diagnostics, post-marketing surveillance of medical products (for example drug, device), care quality, cost reduction and clinical research.

Industry guidelines and resources like the Fast Healthcare Interoperability Resources (FHIR) from Health Level Seven International (HL7) have helped to set a standard, though there is still more work to be done to support organizations to remove barriers toward adoption and make the electronic exchange of data more seamless, with the goal of providing a better provider and patient experience.

 

Third, risks due to siloed data:

When it comes to storing health information including clinical, genomic, device, financial, supply chain and claims, data security is the top priority. Storing patient data across different systems and platforms makes it difficult to deliver personalized care, draw data insights and streamline service.

 

This is a pivotal moment in time when healthcare can take what it's learned over the past year and fix the underlying problems.

 

Perhaps the most important learning is that achieving true healthcare interoperability requires understanding, evaluating and solving issues in the underlying syntactic and semantic characteristics of the data. 

 

Syntactic interoperability requires a common structure so that data can be exchanged and interpreted between health IT systems,

while semantic interoperability requires a common language so that the meaning of data is transferred along with the data itself. This combination supports data fluidity.

 

The industry has made meaningful progress on this front.

 

Unlocking Benefits of Interoperability

 

As technology creates more data across healthcare organizations, applying technologies like artificial intelligence and machine learning will be essential to help take that data and create the shared structure and meaning necessary to achieve interoperability.

 

Shared structure and meaning will enable interoperability solutions that transform data input from various media types and forms: voice, image, scan, PDF, etc., into a common text format which can be shared with and leveraged by every entity in the value chain.

Instead of moving static, electronic documents or faxes like care summaries between healthcare providers, clinical AI-service APIs can enable EHR vendors and health systems to communicate in a standardized way with apps and other EHRs.

 

With access to all available information, advanced analytics and machine learning can then enhance medical and scientific insights tied to patient outcomes in an accurate, scalable, secure and timely manner.

nrip's insight:

As we move toward value based care processes, artificial intelligence and machine learning, paired with data interoperability, will improve patient outcomes while driving operational efficiency to lower the overall cost of care.

 

By enabling data liquidity securely, and supporting healthcare providers with predictive machine learning models, clinicians will be able to seamlessly forecast clinical events like strokes, cancer or heart attacks and intervene early with personalized care and a superior patient experience.

Artificial intelligence could alert for focal skeleton/bone marrow uptake in Hodgkin’s lymphoma patients staged with FDG-PET/CT

Artificial intelligence could alert for focal skeleton/bone marrow uptake in Hodgkin’s lymphoma patients staged with FDG-PET/CT | healthcare technology | Scoop.it

Skeleton/bone marrow involvement in patients with newly diagnosed Hodgkin’s lymphoma (HL) is an important predictor of adverse outcomes1. Studies show that FDG-PET/CT upstages patients with uni- or multifocal skeleton/bone marrow uptake (BMU) when iliac crest bone marrow biopsy fails to find evidence of histology-proven involvement. The general recommendation is, therefore, that bone marrow biopsy can be avoided when FDG-PET/CT is performed at staging.

 

 

Our aim was to develop an AI-based method for the detection of focal skeleton/BMU and quantification of diffuse BMU in patients with HL undergoing staging with FDG-PET/CT. The output of the AI-based method in a separate test set was compared to the image interpretation of ten physicians from different hospitals. Finally, the AI-based quantification of diffuse BMU was compared to manual quantification.

 

Artificial intelligence-based classification

A convolutional neural network (CNN) was used to segment the skeletal anatomy11. Based on this CNN, the bone marrow was defined by excluding the edges from each individual bone; more precisely, 7 mm was excluded from the humeri and femora, 5 mm was excluded from the vertebrae and hip bones, and 3 mm was excluded from the remaining bones.

Focal skeleton/bone marrow uptake

The basic idea behind our approach is that the distribution of non-focal BMU has a light tail and most pixels will have an uptake reasonably close to the average. There will still be variations between different bones. Most importantly, we found that certain bones were much more likely to have diffuse BMU than others. Hence, we cannot use the same threshold for focal uptake in all bones. At the other end, treating each bone individually is too susceptible to noise. As a compromise, we chose to divide the bones into two groups:

  • spine”—defined as the vertebrae, sacrum, and coccyx as well as regions in the hip bones within 50 mm from these locations, i.e., including the sacroiliac joints.

  • other bones”—defined as the humeri, scapulae, clavicles, ribs, sternum, femora, and the remaining parts of the hip bones.

For each group, the focal standardized uptake values (SUVs) were quantified using the following steps:

  1. Threshold computation. A threshold (THR) was computed using the mean and standard deviation (SD) of the SUV inside the bone marrow. The threshold was set to
    =SUVmean+2SD.

 

  • 2. Abnormal bone region. The abnormal bone region was defined in the following way:

    Only the pixels segmented as bone and where SUV > THR were considered. To reduce the issues of PET/CT misalignment and spill over, a watershed transform was used to assign each of these pixels to a local maximum in the PET image. If this maximum was outside the bone mask, the uptake was assumed to be leaking into the bone from other tissues and was removed. Finally, uptake regions smaller than 0.1 mL were removed.

  • 3.Abnormal bone SUV quantification. The mean squared abnormal uptake (MSAU) was first calculated as
    MSAU=meanof(SUVTHR)2overtheabnormalboneregion.

 

To quantify the abnormal uptake, we used the total squared abnormal uptake (TSAU), rather than the more common total lesion glycolysis (TLG). We believe TLG tends to overestimate the severity of larger regions with moderate uptake. TSAU will assign a much smaller value to such lesions, reflecting the uncertainty that is often associated with their classification. Instead, TSAU will give a larger weight to small lesions with very high uptake. This reflects both the higher certainty with respect to their classification and the severity typically associated to very high uptake.
TSAU=MSAU×(volumeoftheabnormalboneregion).

This calculation leads to two TSAU values; one for the “spine” and one for the “other bones”. As the TSAU value can be nonzero even for patients without focal uptake, cut-off values were tuned using the training cohort. The AI method was adjusted in the training group to have a positive predictive value of 65% and a negative predictive value of 98%. For the “spine”, a cut-off of 0.5 was used, and for the “other bones”, a cut-off of 3.0 was used. If one of the TSAU values was higher than the corresponding cut-off, the patient was considered to have focal uptake.

 

Results

Focal uptake

Fourteen of the 48 cases were classified as having focal skeleton/BMU by the AI-based method. The majority of physicians classified 7/48 cases as positive and 41/48 cases as negative for having focal skeleton/BMU. The majority of the physicians agreed with the AI method in 39 of the 48 cases. Six of the seven positive cases (86%) identified by the majority of physicians were identified as positive by the AI method, while the seventh was classified as negative by the AI method and by three of the ten physicians.

 

Thirty-three of the 41 negative cases (80%) identified by the majority of physicians were also classified as negative by the AI method. In seven of the remaining eight patients, 1–3 physicians (out of the ten total) classified the cases as having focal uptake, while in one of the eight cases none of the physicians classified it as having focal uptake. These findings indicate that the AI method has been developed towards high sensitivity, which is necessary to highlight suspicious uptake.

 

Conclusions

The present study demonstrates that an AI-based method can be developed to highlight suspicious focal skeleton/BMU in HL patients staged with FDG-PET/CT. This AI-based method can also objectively provide results regarding high versus low BMU by calculating the SUVmedian value in the whole spine marrow and the liver. Additionally, the study also demonstrated that inter-observer agreement regarding both focal and diffuse BMU is moderate among nuclear medicine physicians with varying levels of experience working at different hospitals. Finally, our results show that the automated method regarding diffuse BMU is comparable to the manual ROI method.

How do patients really feel about virtual care and electronic patient engagement?

How do patients really feel about virtual care and electronic patient engagement? | healthcare technology | Scoop.it

The aim of the Connected Healthcare Study was to understand the impact COVID-19 has had on health care and communication with providers and gain insights into experiences and preferences as it relates to telehealth and online health care tools. 

 

More than two-thirds of U.S. patients (69%) had seen a health care provider via telehealth since the COVID-19 pandemic began, with more than two in five (46%) meeting with a PCP and about one in five (19%) meeting with a mental health care provider. Other providers whom respondents have seen via telehealth since the pandemic began included specialties like ophthalmology and women’s health and orthopedic care, which were not considered typical telehealth users before the pandemic.

 

Telehealth is clearly emerging from the COVID-19 pandemic as the new normal

an overwhelming majority (84%) of respondents who received telehealth services since March 2020 reported that they plan to continue using telehealth appointments in the future, with the top reasons being that it’s more convenient (43%) or to avoid being around people who are ill (39%).

 

One of the most striking results of the survey was that nearly half of U.S. patients (48%) reported that they have sought (4%) or would be likely to seek care (44%) from a different health care provider if their current provider did not offer telehealth appointments.

 

This is clearly a resounding message of support for telehealth from patients to their physicians.

 

As we look back on the broader impact of the COVID-19 pandemic, it will have catapulted patient awareness and acceptance of telehealth and virtual care to the extent that would have been inconceivable before the pandemic.

 

It has also brought to the forefront many other aspects of patient electronic and virtual engagement with providers across all specialties.

nrip's insight:

So patients want an electronic option of care out of convenience and to feel safe. Its unfortunate that it took a pandemic to make the global healthcare systems realize that.

 

There is much scope in the world of Digital Health to make healthcare easier, faster and more accurate for the patients. There are options better for the patients, its better for hospitals, its better for doctors and its definitely better for whoever the payer is in whichever part of the world.

 In morning everyone has to do exercise for at least 30 mins to maintain our body health and be happy in life. We have to eat heathy food to take care of our body because now a days all food products are harm to human health so be aware of it. every three time we have to eat our food on time otherwise we will get ulcer. A healthy diet is a diet the maintain such as protein, micronutrients, nutrients or improves overall health. A healthy diet provides the body with essential nutrition.

 Healthy food does not have merely one but numerous benefits. It helps us in various spheres of life. Healthy food does not only impact our physical health but mental health too. When we intake healthy fruits and vegetables that are full of nutrients, we reduce the chances of diseases.

Key facts

  • A healthy diet helps to protect against malnutrition …
  • Unhealthy diet and lack of physical activity are …
  • Healthy dietary practices start early in life

 obesity is the biggest problems our country is facing now. People are falling prey to obesity faster than expected. However, this can still be controlled. Obese people usually indulge in a lot of junk food. The junk food contains sugar, salt fats and more which contribute to obesity. Healthy food can help you get rid of all this as it does not contain harmful things.

In addition, healthy food also helps you save money. It is much cheaper in comparison to junk food. Plus, all that goes into the preparation of healthy food is also of low cost. Thus, you will be saving a great amount when you only consume healthy food.

A Novel Remote Follow-Up Tool Based on an Instant Messaging/Social Media App for the Management of Patients With Low Anterior Resection Syndrome

A Novel Remote Follow-Up Tool Based on an Instant Messaging/Social Media App for the Management of Patients With Low Anterior Resection Syndrome | healthcare technology | Scoop.it

Low anterior resection syndrome (LARS) is a common functional disorder that develops after patients with rectal cancer undergo anal preservation surgery. Common approaches to assess the symptoms of patients with LARS are often complex and time-consuming.

 

Instant messaging/social media has great application potential in LARS follow-up, but has been underdeveloped.

 

Objective: The aim of this study was to compare data between a novel instant messaging/social media follow-up system and a telephone interview in patients with LARS and to analyze the consistency of the instant messaging/social media platform.

 

 

Methods: Patients with R0 resectable rectal cancer who accepted several defecation function visits via the instant messaging/social media platform and agreed to a telephone interview after the operation using the same questionnaire including subjective questions and LARS scores were included. Differences between the 2 methods were analyzed in pairs and the diagnostic consistency of instant messaging/social media was calculated based on telephone interview results.

Conclusions

The instant messaging/social media system provides a promising solution to accommodate the primary follow-up needs of patients with LARS by integrating complex functional follow-up tools into smartphone apps. Although it is currently not a substitute for manual follow-up, it has the potential of becoming a major LARS screening method. However, further research on response rate, information accuracy, and user acceptance is needed before an advanced system can be implemented

 

nrip's insight:

Common approaches to assess the symptoms of patients in long term treatments, currently in practice, include

  • face-to-face clinic interviews,
  • post or email questionnaires,
  • and telephone interviews,

 

These are time-consuming and often complex.

 

With the popularity of smartphones and mobile internet, remote network technology is changing traditional medical behavior

Where are memories of familiar places are stored in the brain?

Where are memories of familiar places are stored in the brain? | healthcare technology | Scoop.it

As we move through the world, what we see is seamlessly integrated with our memory of the broader spatial environment.

 

How does the brain accomplish this feat? A new study from Dartmouth College reveals that three regions of the brain in the posterior cerebral cortex, which the researchers call "place-memory areas," form a link between the brain's perceptual and memory systems. The findings are published in Nature Communications.

 

For the study, an innovative methodology was employed. Participants were asked to perceive and recall places that they had been to in the real world during functional magnetic resonance imaging (fMRI), which produced high-resolution, subject specific maps of brain activity. Past studies on scene perception and memory have often used stimuli that participants knew of but had never visited, like famous landmarks, and have pooled data across many subjects. By mapping the brain activity of individual participants using real-world places that they had been to, researchers were able to untangle the brain's fine-grained organization.

 

In one experiment, 14 participants provided a list of people that they knew personally and places that they have visited in real-life (e.g., their father or their childhood home). Then, while in the fMRI scanner, the participants imagined that they were seeing those people or visiting those places. Comparing the brain activity between people and places revealed the place-memory areas. Importantly, when the researchers compared these newly identified regions to the brain areas that process visual scenes, the new regions were overlapping but distinct.

 

 "Learning how the mind is organized is at the heart of the quest of understanding what makes us human.

 

The place-memory network provides a new framework for understanding the neural processes that drive memory-guided visual behaviors, including navigation," explains Robertson.

 

The research team is currently using virtual reality technology to explore how representations in the place-memory areas evolve as people become more familiar with new environments.

Bose Launches First FDA-Cleared DTC Hearing Aids | healthcare technology | Scoop.it

Bose is entering the digital health market launch of Bose SoundControl Hearing Aids – the first FDA-cleared, direct-to-consumer hearing aid.

 

Weighing 3 grams each, the new SoundControl™ Hearing Aids are developed for adults with perceived mild to moderate hearing loss. – Paired with the revolutionary Bose Hear app, users can fit, program, and control a SoundControl Hearing Aid for clinically proven, audiologist-quality results — without a doctor visit, hearing test, or prescription. And they can make setting adjustments themselves, in real-time and real-world environments, without assistance from a healthcare professional.

 

Clinical Study Outcomes/Results

In a clinical study with researchers at Northwestern University, Bose CustomTune technology yielded results that were as good if not better than those achieved by traditional prescription-fitting methods used by audiologists. The study’s participants were split into two groups with similar levels of hearing loss. One group used Bose CustomTune technology to self-tune a device, the other had the same device fit and tuned by an audiologist. Participants using Bose CustomTune technology reported being more satisfied with their sound quality than those whose devices were tuned by a hearing health professional.

Role Of AI In Healthcare, TB Prevalence In Nigeria

Role Of AI In Healthcare, TB Prevalence In Nigeria | healthcare technology | Scoop.it

The use of technology in health care has proven to increases care providers, the capabilities and to patients, access to improved quality of healthcare. During the GDD summit organized by BAO Systems, it occurred that some of the most beneficial countries include Nigeria.

 

Speaking at the summit, InStrat Global Health Solution (InStratGHS) CEO, Okey Okuzu, discussed the design, deployment, and impact of Artificial Intelligence (AI) tool – EWORS for TB case finding in Nigeria. EWORS is built on the MediXcel Digital Health Platform by Plus91

 

“Our goal is to overcome barriers to healthcare delivery in low resource settings presented by infrastructural challenges,” he noted. “We achieve this by leveraging mobile health technologies that allow for smooth flow of information across the health system for more effective patient health management or policy decisions regardless of physical location.”

 

The MediXcel-EWORS system is designed to drive actionable AI for public health intervention by sieving through a large volume of data to enable specific geospatial identification of disease cases and also predict the possibility of an outbreak based on historical data and set algorithm threshold.

 

This helps local surveillance personnel to make data-informed decisions to curb the spread of diseases. Field data, captured on android devices wirelessly transferred to a cloud server for storage and analysis.

 

“The EWORS engine conducts advanced analytics to detect unexpected elevations in indicator data and populates this information on real-time GIS heat maps, reports, and alert notifications,” he added.

 

The alert notifications are generated in form of emails/SMS and sent to designated individuals when data from local areas exceed set thresholds, indicating undetected community spread. Designated teams review alarms and mobilize to conduct mass screening outreach at Alarm locations.

 

Under a USAID-funded program led by the KNCV TB Foundation, and in partnership with Plus91 PVT, InStrat GHS deployed its EWORS predictive engine to 14 Nigerian states as a solution to find undetected TB cases in the country. The Analyses of the data from program inception to date demonstrate that prioritization of case finding outreach efforts, based on hotspot analytics and alarms, increases the yield of those efforts.

 

This strategy is crucial to finding missing TB cases and improving case-finding, especially in low resource settings,

Measuring brain blood flow and activity with light

Measuring brain blood flow and activity with light | healthcare technology | Scoop.it

A new, noninvasive method for measuring brain blood flow with light has been developed by biomedical engineers and neurologists at the University of California, Davis, and used to detect brain activation.

 

The new method, functional interferometric diffusing wave spectroscopy, or fiDWS, promises to be cheaper than existing technology and could be used for assessing brain injuries, or in neuroscience research.

 

The human brain makes up 2% of our body weight but takes 15% to 20% of blood flow from the heart. Measuring cerebral blood flow is important for diagnosing strokes, and for predicting secondary damage in subarachnoid hemorrhages or traumatic brain injuries. Doctors who provide neurological intensive care, would also like to monitor a patient's recovery by imaging brain blood flow and oxygenation.

 

Existing technology is expensive and cannot be applied continuously or at the bedside. For example, current techniques to image cerebral blood flow require expensive MRI or computed tomography scanners. There are light-based technologies, such as near-infrared spectroscopy, but these also have drawbacks in accuracy.

 

The new method takes advantage of the fact that near-infrared light can penetrate through body tissues. If you shine a near-infrared laser on someone's forehead, the light will be scattered many times by tissue, including blood cells. By picking up the fluctuation signal of the light that finds its way back out of the skull and scalp, you can get information about blood flow inside the brain.

Patients may not take advice from AI doctors who know their names

Patients may not take advice from AI doctors who know their names | healthcare technology | Scoop.it

As the use of artificial intelligence (AI) in health applications grows, health providers are looking for ways to improve patients' experience with their machine doctors.

 

Researchers from Penn State and University of California, Santa Barbara (UCSB) found that people may be less likely to take health advice from an AI doctor when the robot knows their name and medical history. On the other hand, patients want to be on a first-name basis with their human doctors.

 

When the AI doctor used the first name of the patients and referred to their medical history in the conversation, study participants were more likely to consider an AI health chatbot intrusive and also less likely to heed the AI's medical advice, the researchers added. However, they expected human doctors to differentiate them from other patients and were less likely to comply when a human doctor failed to remember their information.

 

The findings offer further evidence that machines walk a fine line in serving as doctors.

 

Machines do have advantages as medical providers, said Joseph B. Walther, distinguished professor in communication and the Mark and Susan Bertelsen Presidential Chair in Technology and Society at UCSB. He said that, like a family doctor who has treated a patient for a long time, computer systems could — hypothetically — know a patient’s complete medical history. In comparison, seeing a new doctor or a specialist who knows only your latest lab tests might be a more common experience, said Walther, who is also director of the Center for Information Technology and Society at UCSB.

 

“This struck us with the question: ‘Who really knows us better: a machine that can store all this information, or a human who has never met us before or hasn’t developed a relationship with us, and what do we value in a relationship with a medical expert?’” said Walther. “So this research asks, who knows us better — and who do we like more?”

 

Accepting AI doctors

As medical providers look for cost-effective ways to provide better care, AI medical services may provide one alternative. However, AI doctors must provide care and advice that patients are willing to accept, according to Cheng Chen, doctoral student in mass communications at Penn State.

 

“One of the reasons we conducted this study was that we read in the literature a lot of accounts of how people are reluctant to accept AI as a doctor,” said Chen. “They just don’t feel comfortable with the technology and they don’t feel that the AI recognizes their uniqueness as a patient. So, we thought that because machines can retain so much information about a person, they can provide individuation, and solve this uniqueness problem.”

 

The findings suggest that this strategy can backfire. “When an AI system recognizes a person’s uniqueness, it comes across as intrusive, echoing larger concerns with AI in society,” said Sundar.

 

In the future, the researchers expect more investigations into the roles that authenticity and the ability for machines to engage in back-and-forth questions may play in developing better rapport with patients.

New strategies for analytics, patient engagement, telehealth discovered since the pandemic response has reshaped health system priorities.

New strategies for analytics, patient engagement, telehealth discovered since the pandemic response has reshaped health system priorities. | healthcare technology | Scoop.it

In this seventh installment in Healthcare IT News' feature series, Health IT Lessons Learned During the COVID-19 Era, A CIO, a CMIO and two IT directors offer readers what they've discovered since the pandemic response has reshaped health system priorities. They share what they've learned during the past year and discuss how they're applying these lessons to improve their organizations.

 

The increased importance of data and analytics

Overall, the COVID-19 pandemic has catapulted the importance of data analytics and data in general,  For example, the data analytics team at Sanford Health designed an algorithm to sort and pull relevant data from the records of more than 100,000 patients who had been diagnosed with COVID-19, identifying those at highest risk of complications from the virus.

 

More, more, more patient engagement

For Averill of St. Luke's Regional Healthcare System, the impact of patient engagement using patient portal communication, virtual visits and digital appointment-scheduling provided a big lesson.

They also expanded the amount of clinical information sent in real time to the portal since delivering in-person results wasn't possible.

 

When telehealth is not up to par

One major lesson Helio Health learned last year was that its telehealth presence was not up to par. On the other hand, the health system also learned that its teams could implement a telehealth presence fairly quickly. They had to pivot quickly to be certain their patients' critical care would not be interrupted by restrictions put in place as a result of COVID-19

 

Leveraging technology to further strategy

Rollins of Freeman Health System said 2020 was a great year for health IT for many reasons. Many important initiatives were pushed forward and implemented in attempts to react to the ever-changing needs of our customers.

 

Keeping strategies dynamic

Another lesson Rollins has learned over the past year is that health IT and organizational strategies must leave room to adapt to the environment.

 

Streamlined and efficient decision-making

On another front, the pandemic has underscored the importance of having a structured mechanism and system in place for streamlined and efficient decision-making,

 

Standardized processes and equipment

Another lesson Helio Health has learned is the need for standardization of equipment and processes,.

"The vast majority of our computers were desktop PCs," he noted. "With a grant from the FCC, we were able to standardize our outpatient facilities with Microsoft laptops, which allow us to work and provide support from anywhere. Users are able to come and go, from remote work to in-person work, easily. With a recent merger between Helio Health and two other organizations, much of the hardware from the other organizations was dissimilar to Helio Health's standards.

Improving healthcare by better managing unstructured content

Improving healthcare by better managing unstructured content | healthcare technology | Scoop.it
Improving the management of unstructured content is crucial when it comes to creating successful healthcare platforms.

 

Clinicians can build better pictures of their patients when they use healthcare platforms which harness unstructured content, as well as structured content, to create a single source of clinical information.

 

Analysts estimate that as much as 80 per cent of patient information is currently unstructured and is not contained in Electronic Health Records (EHRs). This means that vital clinical information, such as paper records or medical imaging, which does not tick specific boxes, can be overlooked.

AI Toilet Tool Offers Remote Patient Monitoring for Gastrointestinal Health

AI Toilet Tool Offers Remote Patient Monitoring for Gastrointestinal Health | healthcare technology | Scoop.it

Researchers at Duke University are developing an artificial intelligence tool for toilets that would help providers improve care management for patients with gastrointestinal issues through remote patient monitoring.

 

The tool, which can be installed in the pipes of a toilet and analyzes stool samples, has the potential to improve treatment of chronic gastrointestinal issues like inflammatory bowel disease or irritable bowel syndrome, according to a press release.

 

When a patient flushes the toilet, the mHealth platform photographs the stool as it moves through the pipes. That data is sent to a gastroenterologist, who can analyze the data for evidence of chronic issues.

 

A study conducted by Duke University researchers found that the platform had an 85.1 percent accuracy rate on stool form classification and a 76.3 percent accuracy rate on detection of gross blood.

Doctors now must provide patients their health data, online and on demand

Doctors now must provide patients their health data, online and on demand | healthcare technology | Scoop.it

In the United States, on April 5, a federal rule went into effect that requires health care providers to give patients electronic access to their health information without delay upon request, at no cost.

 

Many patients may now find their doctors’ clinical notes, test results and other medical data posted to their electronic portal as soon as they are available.

 

Advocates herald the rule as a long-awaited opportunity for patients to control their data and health.

 

But the rollout of the rule has hit bumps, as doctors learn that patients might see information before they do.

 

Patients have long had a legal right to their medical records but often have had to pay fees, wait weeks or sift through reams of paper to see them.

 
The rule aims not only to remove these barriers, but also to enable patients to access their health records through smartphone apps, and prevent health care providers from withholding information from other providers and health IT companies when a patient wants it to be shared.
 

“This levels the playing field, A decade ago, the medical record belonged to the physician.” as per  Jan Walker, co-founder of OpenNotes“

 

Privacy rules under the Health Insurance Portability and Accountability Act, which limit sharing of personal health information outside a clinic, remain in place, although privacy advocates have warned that patients who choose to share their data with consumer apps will put their data at risk.

 

Studies have shown numerous benefits of note sharing. Patients who read their notes understand more about their health, better remember their treatment plan and are more likely to stick to their medication regimen. Non-white, older or less educated patients report even greater benefits than others.

The Future of Health care needs Doctors and Technologists to work well together

The Future of Health care needs Doctors and Technologists to work well together | healthcare technology | Scoop.it
In a new report - The Truth About Doctors - Covid 19 Edition,  McCann Health identifies four key ways how health care technology has changed since 2016. It highlights the the role of the health care industry in leveraging these changes to carve a new way forward
 
 
In the past, technology has been gradually revolutionizing health care. While patients have adopted it whole heartedly,  It has received push back from various quarters of care providers. Many think it may be having less-positive effects for physicians, some of whom eye it as a threat to doctoring.
 
However, come Covid-19, and the world simultaneously looked up to technology and the medical community in more or less an equal measure.
 
They wanted Tech to help us navigate the pandemic and the medical community to get us out of it, and the need for both to work together and amplify became clearer with each day since the pandemic started
 
As the world moves towards a period of renewal, it will be increasingly important that technology plays a complementary role in care, not just supporting doctoring but super-powering it.
 
Lets look at the 4 main focus areas mentioned in the report.

Technology is redefining the where of care

Home defines most individuals’ physical, mental, and social health. Until recently, home has also been a place where doctors are absent. That changed with Covid-19 and the rapid growth of telemedicine
 
If marketers and others within the health care industry can help doctors acclimatize to the new where of care — supporting them to embrace the home as an extension of their domain rather than something outside of it — health can be elevated in a more holistic level.

Technology can help cultivate inter-professional collaboration

During the pandemic, by using social media and messaging platforms like Twitter and WhatsApp, doctors with diverse backgrounds were able to pool knowledge and emotionally support each other in the collective effort to fight Covid-19. They collaborated in new ways with allied health care professionals, government, and industry, sparking a reimagining of the health ecosystem.
 
The challenge moving forward is giving this organic way of working across care teams and borders a structure to make it scalable.
 
How can the health care system evolve so an expert in peripheral neuropathy in Australia can collaborate with a startup in Belgium? On a more local level, how can health care systems ensure that the different health professionals involved in a patient’s care work together?
 
Secure, shared platforms can nurture a sense of belonging and create a new kind of community for doctors — a “care tribe” that has the power to connect perspectives and passions to advance the experience of care.

Technology can foster continuity and ‘contiguity’

There is a new willingness to take control over personal well-being in light of the pandemic. However this can only go so far in a health care system where time is limited and resources are fragmented.
 
With the proliferation of sensors there may be no better time to apply the quantifiable self to achieve more personalized care. However,  new self-monitoring technologies must be integrated with the full health care ecosystem to make personal health care easier and more seamless, rather than adding to the confusion.
 
Even if technology provides access to more health information, it does not necessarily follow that patients or health care providers will understand it.
 
Health care providers must be taught the skills to not only help patients decipher their health information but to advance their care by proactively identifying and addressing their health risks.
 
With this comes a need to ensure that work is being done in a way that overcomes health inequities rather than heightens them.

Technology can care for the carers

Covid-19 has shown that, instead of posing an existential threat to doctors, technology may be a lifeline for them. By assessing patients before a consult, tech platforms can allow doctors to channel their energy to the problems that need it most. In complicated therapy areas such as oncology, it can ease their load through supporting diagnosis, treatment, and prognosis.
 
In the day-to-day practice of caregiving, technology can enrich relationships by enabling doctors to focus on the human art of medicine. Combined with the flexibility of video consultations and the panoramic perspective of integrated systems, technology can give doctors their time back to practice care on their own terms.
 
 
It’s easy to think that health care is behind the curve when it comes to embracing technology. Covid-19 has shown that this just isn’t the case. When it comes to the relationship between doctors and technology, the pandemic has been an epiphany. Instead of displacing doctors, technology has the power to help them provide better care, supercharging the humanity and empathy that lies at the heart of medicine.
 
Technology has a role in medicine, especially in the service of care.
 
along with my own insights and thoughts
 
nrip's insight:

Covid19's biggest learning has been that technology has a role to play in taking healthcare jump upwards to the next level. The collaboration between technologists and medical professionals holds much promise for the world. We have always said at Plus91, lets all work together today to make a better world, for tomorrow we may not get a chance. Collaborate!  After all, the ultimate goal is the same for everyone - building a world of healthier and happier people, disease free and safe.

Amazon and the Coming Rise of Personal Healthcare

Amazon and the Coming Rise of Personal Healthcare | healthcare technology | Scoop.it

The pandemic has accelerated some trends here, notably telemedicine. That’s given a healthy push to an emerging field – remote diagnostics. Your phone is gradually – with some extensions – turning into a remote diagnostic tool to replace doctor visits and expensive tests. That’s fairly well known, even if it is extraordinary: blood oxygen levels are captured by a device costing less than $20, while an always-on cardiac monitor tracks heart activity, for example.

 

But that’s just the very tip of the iceberg. Remote diagnosis can transform the entire scientific basis of modern medicine. Currently, the gold standard for testing the safety and efficacy of treatments is the randomized control trial (RCT), in which some part of the trial group is treated while another part is not. Both are tracked to see whether the treatment worked, and to look for adverse events like additional illness or even deaths. Outcomes are assessed using standard statistical tools to compare the two groups.

 

This is the gold standard. But it is based on a single core assumption: that humans by and large react similarly to treatments, and hence that the best way to address disease is to identify treatments that work effectively for large numbers of patients. Ideally, treatments work for everyone, although sometimes RCTs and subsequent tracking find groups for which a treatment doesn’t work, or another for which it works especially well – maybe the old (or young), men (or women), or people with specific pre-existing conditions. Still, this is definitely mass-oriented medicine: it’s based on the impact of treatments on what might be called the median patient.

 

Amazon is about to enter healthcare in a big way. It is already planning to offer Amazon Care (its primary care system organized around telehealth) not just to its 1.2 million employees, but to other employers as a service, much like it offered Amazon Web Services 15 years ago (and AWS is now the leading provider of internet infrastructure in the world). It also purchased Pillpack and set up Amazon Pharmacy to deliver medications and other health products online for delivery. But the real revolution is coming inside the home. The Amazon Halo is a new health monitoring device (with some admittedly creepy privacy-related features). It is designed to apply the capabilities of AI to the needs of individual patients. And then there is Alexa, which is clearly going to be Amazon’s device of choice for wellness in the home. It’s already partnered with Sharecare to provide automated advice on 80,000 wellness and health questions, as a first line response to health concerns. Alexa will likely expand, gaining the capacity to integrate remote diagnostics and escalation into Amazon’s wider telehealth network.

 

Still, this mostly sounds like more of the same: using telehealth and the telemedicine capabilities, but mainly just extending what we do now, making it all a bit more convenient – possibly, a lot more convenient. But all these new tools, and especially diagnostics tools, make truly personal medicine possible – like Amazon, all this will be individual-specific: a market segment of you.

Brain-Computer Interface Converts Mental Handwriting into Written Text

Brain-Computer Interface Converts Mental Handwriting into Written Text | healthcare technology | Scoop.it

The combination of mental effort and state-of-the-art technology have allowed a man with spinal injury and immobilized limbs, to communicate by text at speeds rivaling those achieved by his able-bodied peers texting on a smartphone.

 

Call it mindwriting.

 

Scientists at Stanford University, Howard Hughes Medical Institute, and Brown University, developed an implanted brain-computer interface (BCI) technology that uses artificial intelligence to convert brain signals generated when someone visualizes the process of handwriting, into text on a computer, in real time.

 

The team now reports on a trial in which a paralyzed clinical trial participant with a BCI implant was able to “type” words on a computer by merely thinking about the hand motions involved in creating written letters. The software effectively decoded the information from the BCI to quickly convert the man’s thoughts about handwriting into text on a computer screen. In the reported study, the 65-year-old male participant achieved a typing rate of 90 characters per minute, more than double the previous record for typing with a brain-computer interface.

 

The goal is to restore the ability to communicate by text.

 

As per Frank Willett, PhD, the first author of the paper, The system is so fast because each letter elicits a highly distinctive activity pattern, making it relatively easy for the algorithm to distinguish one from another,

 

The new study is part of the BrainGate clinical trial, directed by Leigh Hochberg, MD, a neurologist and neuroscientist at Massachusetts General Hospital, Brown University, and the Providence VA Medical Center. The BrainGate collaboration has been working for several years on systems that enable people to generate text through direct brain control.

 

While a major focus of BCI research has been on restoring gross motor skills, as the team further noted, “rapid sequences of highly dexterous behaviors, such as handwriting or touch typing, might enable faster rates of communication.” What wasn’t known, they pointed out, was whether “… the neural representation for a rapid and highly dexterous motor skill, such as handwriting, also remains intact.”

 

Next, the team intends to work with a participant who cannot speak, such as someone with amyotrophic lateral sclerosis, a degenerative neurological disorder that results in the loss of movement and speech. In addition, they are looking to increase the number of characters available to the participants, such as capital letters and numbers.

Understanding the differences between biological and computer vision

Understanding the differences between biological and computer vision | healthcare technology | Scoop.it

Since the early years of artificial intelligence, scientists have dreamed of creating computers that can “see” the world. As vision plays a key role in many things we do every day, cracking the code of computer vision seemed to be one of the major steps toward developing artificial general intelligence.

 

But like many other goals in AI, computer vision has proven to be easier said than done. In the past decades, advances in machine learning and neuroscience have helped make great strides in computer vision. But we still have a long way to go before we can build AI systems that see the world as we do.

 

Biological and Computer Vision, a book by Harvard Medical University Professor Gabriel Kreiman, provides an accessible account of how humans and animals process visual data and how far we’ve come toward replicating these functions in computers.

 

Kreiman’s book helps understand the differences between biological and computer vision. The book details how billions of years of evolution have equipped us with a complicated visual processing system, and how studying it has helped inspire better computer vision algorithms.

 

Kreiman also discusses what separates contemporary computer vision systems from their biological counterpart.

Hardware differences

Biological vision is the product of millions of years of evolution. There is no reason to reinvent the wheel when developing computational models. We can learn from how biology solves vision problems and use the solutions as inspiration to build better algorithms.

 

Before being able to digitize vision, scientists had to overcome the huge hardware gap between biological and computer vision. Biological vision runs on an interconnected network of cortical cells and organic neurons. Computer vision, on the other hand, runs on electronic chips composed of transistors

 

Architecture differences

There’s a mismatch between the high-level architecture of artificial neural networks and what we know about the mammal visual cortex.

Goal differences

Several studies have shown that our visual system can dynamically tune its sensitivities to the common. Creating computer vision systems that have this kind of flexibility remains a major challenge, however.

Current computer vision systems are designed to accomplish a single task.

Integration differences

In humans and animals, vision is closely related to smell, touch, and hearing senses. The visual, auditory, somatosensory, and olfactory cortices interact and pick up cues from each other to adjust their inferences of the world. In AI systems, on the other hand, each of these things exists separately.

Influence Mechanism of the Affordances of Chronic Disease Management Apps on Continuance Intention

Influence Mechanism of the Affordances of Chronic Disease Management Apps on Continuance Intention | healthcare technology | Scoop.it

Mobile health apps are becoming increasingly popular, and they provide opportunities for effective health management.

 

Existing chronic disease management (CDM) apps cannot meet users’ practical and urgent needs, and user adhesion is poor. Few studies, however, have investigated the factors that influence the continuance intention of CDM app users.

 

Objective: Starting from the affordances of CDM apps, this study aimed to analyze how such apps can influence continuance intention through the role of health empowerment.

 

Methods: Adopting a stimulus-organism-response framework, an antecedent model was established for continuance intention from the perspective of perceived affordances, uses and gratifications theory, and health empowerment. Perceived affordances were used as the “stimulus,” users’ gratifications and health empowerment were used as the “organism,” and continuance intention was used as the “response.” Data were collected online through a well-known questionnaire survey platform in China, and 323 valid questionnaires were obtained. The theoretical model was tested using structural equation modeling.

 

Results: Perceived connection affordances were found to have significant positive effects on social interactivity gratification (t717=6.201, P<.001) and informativeness gratification (t717=5.068, P<.001).

 

Perceived utilitarian affordances had significant positive effects

  • on informativeness gratification (t717=7.029, P<.001),
  • technology gratification (t717=8.404, P<.001),
  • and function gratification (t717=9.812, P<.001).

 

Perceived hedonic affordances had

  • significant positive effects on function gratification (t717=5.305, P<.001)
  • and enjoyment gratification (t717=13.768, P<.001).

 

Five gratifications (t717=2.767, P=.005; t717=4.632, P<.001; t717=7.608, P<.001; t717=2.496, P=.012; t717=5.088, P<.001) had significant positive effects on health empowerment.

 

Social interactivity gratification, informativeness gratification, and function gratification had significant positive effects on continuance intention.

 

Technology gratification and enjoyment gratification did not have a significant effect on continuance intention.

 

Health empowerment had a significant positive effect on continuance intention. Health empowerment and gratifications play mediating roles in the influence of affordances on continuance intention.

 

Conclusions: Health empowerment and gratifications of users’ needs are effective ways to promote continuance intention. The gratifications of users’ needs can realize health empowerment and then inspire continuance intention. Affordances are key antecedents that affect gratifications of users’ needs, health empowerment, and continuance intention.

 

The results indicated that users’ perceptions of an app’s affordances can promote the gratification of needs, and the gratification of key needs (ie, social interactivity, informativeness, technology, and function gratification) can stimulate users’ continuance intention. At the same time, the gratification of users’ needs can promote users’ cognitions of health empowerment, thus stimulating continuance intention. Health empowerment was found to play a mediating role in the influence of gratification on continuance intention. From a practical perspective, app service providers should design apps from the perspective of social interaction (eg, providing social networks), utilitarian functions (eg, health self-management), and hedonic functions (eg, enhancing the user’s interest). By meeting users’ various needs, app developers can improve the user’s ability to control his or her own health, thus achieving the purpose of extending the life of the app.

Can a smartphone be used to reliably detect early symptoms of autism spectrum disorder?

Can a smartphone be used to reliably detect early symptoms of autism spectrum disorder? | healthcare technology | Scoop.it

Atypical eye gaze is an early-emerging symptom of autism spectrum disorder (ASD) and holds promise for autism screening.

 

Current eye-tracking methods are expensive and require special equipment and calibration. There is a need for scalable, feasible methods for measuring eye gaze.

 

This case-control study examines whether a mobile app that displays strategically designed brief movies can elicit and quantify differences in eye-gaze patterns of toddlers with autism spectrum disorder (ASD) vs those with typical development.

 

In effect, using computational methods based on computer vision analysis, can a smartphone or tablet be used in real-world settings to reliably detect early symptoms of autism spectrum disorder? 

 

Findings

In this study, a mobile device application deployed on a smartphone or tablet and used during a pediatric visit detected distinctive eye-gaze patterns in toddlers with autism spectrum disorder compared with typically developing toddlers, which were characterized by reduced attention to social stimuli and deficits in coordinating gaze with speech sounds.

 

What this means

These methods may have potential for developing scalable autism screening tools, exportable to natural settings, and enabling data sets amenable to machine learning.

 

 

Conclusions and Relevance

The app reliably measured both known and new gaze biomarkers that distinguished toddlers with ASD vs typical development. These novel results may have potential for developing scalable autism screening tools, exportable to natural settings, and enabling data sets amenable to machine learning.

nrip's insight:

Identifying autism in toddlers is helpful to starting care for it early. This study's results demonstrate that with an app based approach coupled with an algorithmic approach, it is certainly possible to get possibly affected children in for detailed clinical evaluations earlier and fairly cheaply.

 

Thus, doctors will be able to install an app on their smartphone/tablet, one that is capable of analyzing the visual gaze of a toddler in order to determine if they may be on the autism spectrum.

And, in time,  parents and family members will be able to download it onto their own smartphones/tablets  carry out the screening themselves.

The Smallest-Ever Injectable Chip Hints at a Cybernetic Medicine

The Smallest-Ever Injectable Chip Hints at a Cybernetic Medicine | healthcare technology | Scoop.it

The world's smallest computer chip is the size of a dust mite! Check out the future of medical tech.

 

Electronics are getting imperceptibly small, opening new avenues for medical technology to place advanced monitoring and treatment devices inside our bodies. And Columbia University engineers just demonstrated a new and revolutionary version of this, creating the world's smallest single-chip system ever developed, according to a recent study published in the journal Science Advances.

 

And, critically, the tiny new chip can be implanted via a hypodermic needle to measure internal body temperature, and potentially much more.

A tiny computer chip was implanted into seven mice at once

The implant created by the engineers at Columbia is record-breakingly small, but it's also breaking new ground in simply existing as a wholly functional, electronic circuit whose total volume is less than 0.1 cubic millimeter. In other words, it's the size of a dust mite, not to mention far more compact than the world's smallest computer, which is a cube-shaped device precisely 0.01-inches (0.3 mm) on each side.

 

The smaller, new chip is only visible with a microscope, and pushed the envelope in power-sourcing and communications ingenuity design.

 

The injectable chip could serve as an 'early warning' system against future outbreaks

Such tiny chips could also be implanted in the human body, and then communicate measured information and data wirelessly through ultrasound. As the device stands, it can only measure body temperature, but it could eventually also monitor respiratory function, glucose levels, and blood pressure. "We wanted to see how far we could push the limits on how small a functioning chip we could make," said Ken Shepard, leader of the Columbia study, in a report from New Atlas. "This is a new idea of 'chip as system' — this is a chip that alone, with nothing else, is a complete functioning electronic system."

Real-Time EHR Mortality Prediction During the COVID-19 Pandemic

Real-Time EHR Mortality Prediction During the COVID-19 Pandemic | healthcare technology | Scoop.it

We developed and validated an accurate in-hospital mortality prediction score in a live EHR for automatic and continuous calculation using a novel model that improved upon SOFA.

 

The COVID-19 pandemic created an emergent need for a novel, accurate, and location and context-sensitive EHR-computable tool to predict mortality in hospitalized patients with and without COVID-19. Because developing a new score can take years, a predictive model must rely on well-validated scores.

 

In contrast, COVID-19 is a novel disease for which existing scores may be of limited but unknown predictive value.

 

As such, a predictive framework relying on multiple previously validated scores that can incorporate new information but only keeps the new inputs that explicitly improve performance is required. Stacked generalization provides a solution. A stacked model is built upon one or more baseline model(s) (e.g. SOFA) and incorporates additional models only when they improve prediction.

 

Materials and Methods

We developed, verified, and deployed a stacked generalization model to predict mortality using data available in the EHR by combining five previously validated scores and additional novel variables reported to be associated with COVID-19-specific mortality.

 

We verified the model with prospectively collected data from 12 hospitals in Colorado between March 2020 and July 2020. We compared the area under the receiver operator curve (AUROC) for the new model to the SOFA score and the Charlson Comorbidity Index.

 

Results

The prospective cohort included 27,296 encounters, of which 1,358 (5.0%) were positive for SARS-CoV-2, 4,494 (16.5%) required intensive care unit care, 1,480 (5.4%) required mechanical ventilation, and 717 (2.6%) ended in death. The Charlson Comorbidity Index and SOFA scores predicted mortality with an AUROC of 0.72 and 0.90, respectively. Our novel score predicted mortality with AUROC 0.94. In the subset of patients with COVID-19, the stacked model predicted mortality with AUROC 0.90, whereas SOFA had AUROC of 0.85.

 

Discussion

Stacked regression allows a flexible, updatable, live-implementable, ethically defensible predictive analytics tool for decision support that begins with validated models and includes only novel information that improves prediction.

Grant awarded to develop artificial intelligence to improve stroke screening and treatment in smaller hospitals

Grant awarded to develop artificial intelligence to improve stroke screening and treatment in smaller hospitals | healthcare technology | Scoop.it

New artificial intelligence technology that uses a common CT angiography (CTA), as opposed to the more advanced imaging normally required to help identify patients who could benefit from endovascular stroke therapy (EST), is being developed at The University of Texas Health Science Center at Houston (UTHealth).

 

Two UTHealth researchers worked together to create a machine-learning artificial intelligence tool that could be used for assessing a stroke at every hospital that takes care of stroke patients - not just at large academic hospitals in major cities. 

 

Research to further develop and test the technology tool is funded through a five-year, $2.5 million grant from the National Institutes of Health (NIH). 

 

"The vast majority of stroke patients don't show up at large hospitals, but in those smaller regional facilities. And most of the emphasis on screening techniques is only focused on the technologies used in those large academic centers. With this technology, we are looking to change that," said Sunil Sheth, MD, assistant professor of neurology at McGovern Medical School at UTHealth.

 

Sheth set out with Luca Giancardo, PhD, assistant professor with the Center for Precision Health at UTHealth School of Biomedical Informatics, to develop a quicker way to assess patients. The result was a novel deep neural network architecture that leverages brain symmetry. Using CTAs, which are more widely available, the system can determine the presence or absence of a large vessel occlusion and whether the amount of "at-risk" tissue is above or below the thresholds seen in those patients who benefitted from EST in the clinical trials.

 

"This is the first time a data set is being specifically collected aiming to address the lack of quality imaging available for stroke patients at smaller hospitals," Giancardo said.
