Washington Post: These Louisiana physicians can monitor your blood pressure — and you don’t even have to leave your living room

Interesting article from the Washington Post. What's interesting is that they focus on high blood pressure. Yes, high blood pressure is a concern, but with heart patients of even greater concern is low blood pressure. Nevertheless, it does discuss in detail and in a readable manner, the real benefits of remote monitoring and remote patient management.

Here's the link to the article:  https://www.washingtonpost.com/business/economy/these-louisiana-physicians-can-monitor-your-blood-pressure--and-you-dont-even-have-to-leave-your-living-room/2018/07/11/6d57f198-7beb-11e8-93cc-6d3beccdd7a3_story.html?utm_term=.383dd5c9dfb0

It's worth your time to read.

Remote Patient Monitoring System Market Expected to Grow USD 31 Bn by 2023

https://sectorhealthcare.com/remote-patient-monitoring-system-market-expected-to-grow-usd-31-bn-by-2023/

An article pointing to a research report regarding the growth in the market for remote monitoring and by implication, remote patient management.

From the article:

The global remote patient monitoring market was valued at around USD16 billion in 2017 and is expected to cross USD31 billion by 2023, increasing at an annual growth rate of 12% between 2017 and 2023. The increase in the geriatric population and individual spending on the medical treatments have supported the need for remote patient monitoring technology.

... 
There is a "however" in this article. As expected with the medical establishment, there are some concerns, slow-downs and possible blockers.

Also from the article:

However, hospitals in few countries are not showing any willingness to adopt these remote monitoring technologies owing to the huge expenditure involved in the setup of infrastructure and equipment, and the shortage of skilled human resources. Patients are advised by few healthcare professionals to implement the technology by themselves to avoid hospital expenses and repeated clinical visits. Strict government regulations and lack of proper reimbursement mechanism are also impeding the growth of global remote patient monitoring market.

Like it or not, governments ... most likely national and regional/state ... will need to be the ones pressing the medical establishments to make changes because governments in so many countries ... and believe or not, including the US because so much health care is paid out of Medicare and Medicaid funds ... are the ones ultimately footing the bill. 

Here's a link to the report. https://www.researchcosmos.com/reports/global-remote-patient-monitoring-system-market-professional-survey-report-2018/19032600

I warn you that it's an expensive report. You may work for a company that either can pay for this report or has access to the reporting service.

Also the article (and the report) discuss an area of remote monitoring and remote patient management that I have extensive experience in and that I've discussed in this blog:

Cardiac monitors are the most preferred remote monitoring systems due to the rise in heart-related diseases causing more than 31% of deaths world. Cardiac monitors include heart rate monitor, fetal heart rate monitors, ECG monitor, and blood pressure monitors that are having a huge demand in the global markets. To capitalize on the growing cardiovascular disease conditions, product developers across the world are implementing portable and wireless ECG monitors that easily carried around to anyplace.

Remote Monitoring Keeps Patients with Chronic Conditions out of the Hospital

https://www.prnewswire.com/news-releases/remote-monitoring-keeps-patients-with-chronic-conditions-out-of-the-hospital-300683952.html

From previous studies we know the economic value and cost reductions of remote monitoring and remote patient management. Here is an article about a study by Mercy Virtual regarding the value to patients of being remotely monitored and remotely managed. The results of this study although not surprising show without a doubt the use of remote monitoring and remote patient management have profoundly positive results not only for patients but for wider medical system. And that remote monitoring and remote patient management should be employed not only for patients who live long distances from medical facilities, but for all patients who require frequent monitoring and attention.

Overview and results of the study:


Mercy Virtual piloted vEngagement in WashingtonMissouri, beginning in September 2015. The program is now available at Mercy hospitals and clinics in ArkansasKansasMissouri and Oklahoma.
Results of the vEngagement program have been impressive among nearly 1,000 patients:
    • 50 percent reduction in hospital readmissions 
    • 50 percent reduction in emergency department visits and hospitalizations 
    • 98 percent of patients who are extremely satisfied or satisfied

The article includes a case study of the experiences of one of the patients in the study:

After several hospitalizations for breathing problems over two years, Dolorse Murray agreed last September to try a home-based health management program her primary care physician believed would improve her health.
Murray, 71, of Neosho, Missouri, has chronic heart and lung conditions that make breathing difficult and sometimes lead to swelling in her legs and feet. Through the program, called vEngagement, a Mercy Virtual care team monitors Murray and makes suggestions about changes at home to better manage her symptoms.
After just a few months in the program, Murray said she feels better and is able to breathe easier. She has returned to her favorite hobbies, like gardening and painting, which she was too sick to do last year. 
"This is the most wonderful program, and I tell a lot of people about it," said Murray. "I feel like it's saved my life."
Murray meets by phone with her care team several times per month to discuss how she is feeling and determine any changes to her treatment plan. She can also hit a button to let Mercy Virtual co-workers know she doesn't feel well.

Harvard Study: Hospital Computerization Does Not Improve Performance (Updated 6 Apr 2015)

A republication of an earlier posting of this study. It's timely in the light of New York Times Opinion piece, "Why is health care tech still so bad?"

Title: Hospital Computing and the Costs and Quality of Care: A National Study
Authors: David U. Himmelstein, MD, Adam Wright, PhD, Steffie Woolhandler, MD, MPH Department of Medicine, Cambridge Hospital/Harvard Medical School, Cambridge, Mass;  Clinical Informatics Research and Development, Partners Healthcare System, Boston, Mass.


ABSTRACT**

BACKGROUND: Many believe that computerization will improve health care quality, reduce costs, and increase administrative efficiency. However, no previous studies have examined computerization’s cost and quality impacts at a diverse national sample of hospitals.
METHODS: We linked data from an annual survey of computerization at approximately 4000 hospitals for the period from 2003 to 2007 with administrative cost data from Medicare Cost Reports and cost and quality data from the 2008 Dartmouth Health Atlas. We also compared hospitals included on a list of the “100 Most Wired” with others.
RESULTS: Hospitals on the “Most Wired” list performed no better than others on quality, costs, or administrative costs.
CONCLUSION: As currently implemented, hospital computing might modestly improve process measures of quality but does not reduce administrative or overall costs.

Summary and Critique of the Study


Researchers from Harvard University collected data over 5 years (2003 to 2007) from a variety of different hospital data repositories


The hospital computer applications considered for this study included:

Clinical applications subscore (8 applications)

  • Clinical data repository
  • Computerized practitioner order entry
  • Data warehousing and mining, clinical
  • Electronic medical record
  • Laboratory information system
  • Nursing documentation
  • Order entry
  • Physician documentation
Administrative applications (patient-related) subscore (4 applications)

  • Nurse acuity
  • Nurse staffing scheduling
  • Patient billing
  • Patient scheduling
Administrative applications (other) sub-score (12 applications)
Budgeting

  • Case mix management
  • Cost accounting
  • Credit collections
  • Eligibility
  • Data warehousing and mining, financial
  • Electronic data interchange
  • Executive information system
  • General ledger
  • Materials management
  • Personnel management
  • Staff scheduling 
The authors created a overall computerization score and three subscores on the basis of determining whether or not the hospital had computerized the areas listed above.  

Concerns regarding the construction and use of computerization score(s).
  • No details were disclosed on how they created the level of computerization score.  
  • Furthermore, no details were disclosed regarding the score distribution.  
  • >> This is particularly important because correlation depends on a wide distribution of values as well as a reasonably even distribution across the range of values.  
  • No information was forthcoming from the authors about these characteristics of the data set.   
  • If the computerization scores were tightly clustered, then the r values (Pearson product-moment correlations) would hover around zero - and they did.

Suggested that increases in computerization may not be having the desired effects in reducing costs and increasing productivity and performance.

With respect to clinical significance of hospital computerization, the authors concluded that:

  • Hospital computerization has not, thus far, achieved savings on clinical or administrative costs. 
  • More computerized hospitals might have a slight quality advantage for some conditions.
  • No reliable data support claims of cost savings or dramatic quality improvement from electronic medical records.

UK Perspective Regarding FDA Regulatory Requirements

A Linked-In colleague posted a link to this article. I read it and found it interesting enough to post the link and comment on it. It's by a UK publication and discusses the FDA regulatory process as it relates to Human Engineering requirements for device approval for commercialization.

Here's the link:
http://www.emdt.co.uk/daily-buzz/what-are-fda-usability-testing-requirements-device-approval?cid=nl.qmed01.20150325

In addition, I provide my own perspective on the article in the "Commentary" section below. I do not critique the article. I only attempt to expand on a few points from it.

But first, a brief summary of the article.

Article Summary


Medical errors have become an increasing concern of the FDA. I became interested in medical errors when I was a consultant at St. Jude Medical Cardiac Rhythm Division in Sylmar, CA. During my time at St. Jude (2009-2010), deaths by medical error were being reported as being 100,000 to 120,000 per year. Last year, I posted links to two articles that stated that deaths by medical errors could be closer to 400,000 per year. (http://medicalremoteprogramming.blogspot.com/2014/07/rip-death-by-medical-error-400000-year.html)

It has been noted by the FDA a large proportion of medical errors can be attributed to poorly designed medical device user interfaces. Since a fundamental mission of the FDA is increasing patient safety and reducing injuries and fatalities in the practice of medicine, the FDA has begun placing greater emphasis on improving the usability of medical device user interfaces.

This article provides measures that show the FDA's increasing emphasis on usability and human factors issues by showing the increasing frequency that companies seeking medical device clearance for the US market mention the terms "usability" and "human factors." Figure 1 from the article clearly shows the increasing usage of these terms in company filings.



The focus should be on the trends, not the absolute numbers because not all filing documents have been included in the count. But the trend clearly shows an increased emphasis by companies to increasingly use the terms "usability" and "human factors" in their filings with the FDA. The two figures that follow suggest the degree that companies have incorporated the FDA prescribed human factors engineering process and design guidance documentation.

The documents listed below are specifically targeted to defining and supporting the human factors engineering process and the development of the Human Engineer File that's included as part of a company's filing to the FDA.


  • ISO 62366, Medical Devices - Application of Usability Engineering to Medical Devices
  • AAMI / ANSI HE75:2009, Human Factors Engineering - Design of Medical Devices (General)

I'll discuss the documents above in greater detail and describe how they're intended to fit within the human factors engineering process when developing medical devices.


  • IEC 60601-1-6 Medical electrical equipment - Part 1-6 General requirements for Safety - Collateral standard: Usability
  • IEC 60601-1-8 Ed. 1, Medical Electrical Equipment - Part 1-8: General Requirements for Safety - Collateral Standard: Alarm Systems - Requirements, Tests and Guidance - General Requirements and Guidelines for Alarm Systems in Medical Equipment (General)

The two documents above are engineering standards. They're engineering specifications that medical devices must meet. They are technical and specific.

I show Figure 3 from the article before showing Figure 2. 



The increasing reference of 60601-1-8 is not surprising given the increased emphasis on safety. My real interest is in the significant increase in reference to ISO 62366. As mentioned, this is process standard the lays out how human factors engineering should be engaged to reduce "use errors." The emphasis in this standard is on the reduction of risk. Risk management is extremely well embedded in the medical device design and engineering process. It would seem that from a cultural perspective, ISO 62366 fits with the medical device engineering process. 

I want to contrast the dramatic, increasing references to ISO 62366 with the references to AAMI/ANSI HE75 shown in Figure 2 below.



References to AAMI/ANSI HE75 rise and fall from 2010 to 2013 instead of a steady upward trend that you see with ISO 62366 in Figure 3. I would like to emphasize that ISO 62366 and AAMI/ANSI HE75 should be considered as companion documents. (I'll expand on this in the Commentary section below.)

Commentary


The article does support the contention that the FDA and the companies it regulates are paying increasing attention to usability and human factors. That they're paying enough attention is another matter entirely. As new medical devices are introduced we should see two things. First, the use error rate for the newly introduced medical devices (once users have adapted to them) should decline in relationship to other similar devices currently in use. Second, we should see over time the number of per year of deaths and injuries from medical errors begin to decline. This will take time to detect.

Without a doubt, the push by the FDA to define a human engineering process in the design and testing of medical devices, and to press for testing under actual or simulated conditions is needed. In many ways the FDA is mirroring many of the processes that have already been adopted by the US Department of Defense (DoD) in the area of human engineering. Admittedly, the DoD doesn't always get it right, there is an understanding within the DoD that it is important ... life saving, battle-winning important ... to insure that those at the controls can do their jobs quickly, effectively and with as few errors as possible.  So from that standpoint, the FDA has adopted processes from programs that have proven effective. But the FDA has just passed the starting line. And much more will be required going forward.

ISO 62366 vs AAMI/ANSI HE75

As I mentioned earlier ISO 62366 and AAMI/ANSI HE75 should be consider complementary or companion documents. HE75 is a much larger document than 62366 and includes a significant amount of device design guidance and guidelines. 62366 is almost entirely a process document that's devoted to directing how to go about managing the research and development process of a medical device. In addition, the focus of 62366 is managing risks, risks in the realm of reducing use errors.

I found it interesting that references to HE75 were not increasing at the rate as references to 62366. I would have expected Figures 2 and 3 to have a similar appearance with respect to 62366 and HE75 in large part because the documents significantly overlap. In fact I might have reasonably expected references to HE75 to outpace 62366 because HE75 includes design specific guidelines in addition.

One possible reason for references to HE75 not being referenced in the same accelerated way as HE75 may have to do with the fact that the European Union has not adopted HE75, so it's required for medical devices that will be marketed in the EU (CE).  (I am currently unaware of the regulatory requirements of other countries on this matter.) Medical device companies are international companies and the documents that they file in one country are generally the same in each country. Thus since the EU hasn't adopted HE75, references to HE75 and HE75's use as a foundational process and design document may be less.

DESIGN RATIONALE

I'm not sure that this is true at this point in time, but I am certain that the following will be true going forward at some time in the future. I believe that the FDA will hold companies to account for their user interface designs. I believe that the FDA will demand that companies clearly define how they came up with their user interface designs and that those designs are well-grounded in empirical evidence.

This is what I mean ... the FDA will demand that the design choices ... these include: controls, placement of controls, number of controls, actions performed by controls, the way the control responds, methods for interacting with the device (e. g., touch screen, buttons, mouse), size of the display, etc. ... for medical device user interfaces must be grounded in empirical data.

Commercial websites are often designed by graphic artists. Often times the design of webpages reflect the artist's aesthetic sensibilities. Layout appear they way that they do because they look good.

I believe that the FDA will require that user interface designs for medical devices have an empirically grounded design rationale. Companies will be required to point to specific research finding to justify the design and the design choices that they made. Furthermore, as the design of the user interface evolves with each iteration of testing, the FDA will require that changes to the design be based on research findings.

Finally, I believe that soon if it is not occurring already, that the FDA will require:

  1. That companies submit documentation to show in detail the full evolutionary design process beginning from product inception, including ...
  2. Detailed pre-design research ... population(s), method(s), research questions and rationale, etc ... as well as the findings and what they suggest for the design of the user interface
  3. A design that includes with a full discussion of the design rationale ... why was it designed the way it was ... 
  4. A detailed description of the evolution of the design that include full and clear justification(s) for each change in the design ... and require that changes be grounded empirical data 
  5. A full description of pre-commercialization testing process and method ... with a clear justification for why this testing meets FDA testing requirements
  6. And a complete and clear analysis of the testing data.
What I'm suggesting above is that the process of designing and testing a medical device user interface should be more than going through the prescribed steps, collecting the data, doing the tests, etc. There should be a clear thread that ties all the steps together. When in a subsequent step, one should be able to point back to the previous steps for the rationale to explain why the user interface was designed to appear and operate the way it does ... to this point.

As near as I can tell, what I described above is rigorous than is currently required by the FDA. However, I believe that it would be in any company's best interest to follow what I've suggested because there may come a time when the FDA's enforcement becomes more rigorous. 

Another reason may be lawsuits. If a company can show that it went beyond the FDA's regulatory requirements at the time, those suing would likely have less of a chance of collecting damages. And if damages were awarded, they may likely be lower. Also, if the company went beyond the FDA requirements, it would be likely that there would be fewer people injured and that should lower damages.

FINALLY

This article has been a springboard for me to discuss a number of topics related to human engineering for medical devices user interfaces. This topic will remain a central part of this blog. I'll return this within a week or two, and discuss in depth other topics related to the human engineering process for medical device user interfaces.

From The Hindu: Indian Product Team has Produced Star Trek-Like Medical Hand-Held Scanner

This development is something worth watching ...

Here's the link to the article: http://www.thehindubusinessline.com/news/states/soon-a-tricorder-to-monitor-diagnose-health-conditions/article7040704.ece

Here are some quotes:

An Indian team is close to developing an electrical device that can diagnose 15 different medical conditions and can monitor vital signs for around 72 hours.
Chennai-based American Megatrends India is developing a medical hand-held scanner that is worthy to be included in the television show Star Trek. 
American Megatrends’ medical device is a wireless health monitoring tool that can monitor a battery of vital statistics that include blood pressure, heart rate, oxygen saturation, respiratory rate and temperature, as well as atrial fibulation, sleep apnea, stroke, diabetes, etc. The device can collect large volumes of data from ongoing measurement of health states through a combination of wireless sensors, imaging technologies, and portable, non-invasive techniques. The stream of data generated will be stored in the cloud, currently on AMI’s own servers, with plans afoot to work with major cloud operators such as Apple and Google.

Article speaks for itself. No commentary necessary.

Welch Allyn Published Patent Application: Continuous Patient Monitoring

I decided to review this patent application in light of the New York Times Opinion piece I commented on. Here's the to my commentary: http://medicalremoteprogramming.blogspot.com/2015/03/new-york-times-opinion-why-health-care.html

Also, I've gone back to the origins of this blog ... reviewing patents. The first patent I reviewed was one from Medtronic. Here's the link: http://medicalremoteprogramming.blogspot.com/2009/09/medtronics-remote-programming-patent.html

The issue raised of particular interest was the high "false alarm" rate generated reported by the author that would lead medical professionals to disregard warnings generated by their computer systems. I wrote that I wanted to follow-up on the issue of false alarms.

The patent application (the application has been published, but a patent has not yet been granted) describes an invention intended to 1) perform continuous automated monitoring and 2) lower the rate of false alarms.

Here are the details of the patent application so that you can find it yourself if you wish:



The continuous monitoring process from a technical standpoint is not all that interesting or new. What is interesting is the process they propose to lower the false alarm rate and determine whether this process in turn will not lower the false negative rate.

Proposed Process of Lowering False Alarms

As mentioned in my earlier article, it appears that false alarms have been a significant issue for medical devices and technology. Systems that issue too many false alarms issue warnings that are often dismissed or ignored. Or waste the time and attention of caregivers who spend time and energy on responding to a false alarm. This patent application is intended to reduce the number of false alarms. However, as I mentioned earlier, can it do that by not increasing the number of false negatives, that is, failure to detect when there is a real event where an alarm should be going off.

Getting through all the details of the patent application and trying to make sense of what they're trying to convey, the following is what I believe is the essence of the invention:


  • Measurement a sensor indicates an adverse patient conditions and an alarm should be initiated.
  • Before the alarm is initiated, the system cross-checks against other measurements that are: 
              1) from another sensor measuring essentially the same physiological condition as the
                  sensor that detected the adverse condition, the measurement from the second sensor
                  would confirm the alarm condition or indicate that an alarm condition should not exist; or
              2) from another sensor or sensors that take physiological measurements that would confirm
                  the alarm condition from the first sensor or indicate that an alarm condition should not
                  exist.

In this model at least two sensors must provide measurements that point to an alarm state.

Acceptable Model for Suppressing False Alarms and Not Increasing False Negatives?

Whatever you do in this domain of detecting adverse patient conditions, you don't want to lower your accuracy of detecting the adverse condition. That is, increase your false negative rate.

So is this one way of at least maintaining your currently level of detecting adverse events and lowering your false alarm rate? On the face of it, I don't know. But it does appear that it might be possible.

One of the conditions the inventors suggest that initiates false alarms are those times when patients move or turn over in their beds. This could disconnect a sensor or cause it to malfunction. A second sensor taking the identical measurement may not functioning normally and have a measurement from the patient indicating that nothing was wrong. The alarm would be suppressed ... although, if a sensor was disconnected, one would expect that there would be a disconnected sensor indicator would be turned on.

Under the conditions the inventors suggest, it would appear that cross checking measurements might reduce false positives without increasing false negatives. I would suggest that care should be given to insure that a rise in false negative rates do not increase. With array of new sensors and sensor technology becoming available, we're going to need to do a lot of research. Much of it would be computer simulations to identify those conditions were an adverse patient condition goes undetected or suppressed by cross-checking measurements.

Post Script

For those who do not know, I am on numerous patents and patent applications (pending patents). Not only that I have written the description section of a few patent applications. So I have a reasonable sense of what is what is not patentable ... this is in spite of the fact that I'm an experimental, cognitive psychologist and we're not general known for our patents.

So, what is my take on the likelihood that this applications will be issued a patent? My sense is not likely. As far as I can tell there's nothing really new described in this application. The core of the invention, the method for reducing false alarms, is not new. Cross-checking, cross-verifying measurements to determine if the system should be in an alarm state is not new. As someone who has analyzed datasets for decades, one of first things that one does with a new dataset is to check for outliers and anomalies - these are similar alarm conditions. One of the ways to determine whether an outlier is real, is to cross check against other measures to determine if they're consistent with and predictive of the outlier. I do not see anything that is particularly new or passes what known in patent review process as the "obviousness test." For me cross checking measures does not reach the grade of patentability.

Frontline Documentary: The Vaccine War

This doesn't have much to do with medical monitoring or remote programming, but if you're interested in vaccination and public health, this is a must-see documentary.

New York Times Opinion: Why Health Care Tech Is Still So Bad

This was an opinion piece published 21 March 2015 in the New York Times written by Robert M. Wachter, Professor of Medicine, University of California, San Francisco and author of "The Digital Doctor: Hope, Hype, and Harm at the Dawn of Medicine’s Computer Age” also published in the New York Times.

Here's the link to the article: http://www.nytimes.com/2015/03/22/opinion/sunday/why-health-care-tech-is-still-so-bad.html?smid=nytcore-ipad-share&smprod=nytcore-ipad

I have commented on several quotes from the article.

1. "Even in preventing medical mistakes — a central rationale for computerization — technology has let us down. (My emphasis.) A recent study of more than one million medication errors reported to a national database between 2003 and 2010 found that 6 percent were related to the computerized prescribing system.

At my own hospital, in 2013 we gave a teenager a 39-fold overdose of a common antibiotic. The initial glitch was innocent enough: A doctor failed to recognize that a screen was set on “milligrams per kilogram” rather than just “milligrams.” But the jaw-dropping part of the error involved alerts that were ignored by both physician and pharmacist. The error caused a grand mal seizure that sent the boy to the I.C.U. and nearly killed him.

How could they do such a thing? It’s because providers receive tens of thousands of such alerts each month, a vast majority of them false alarms. (My emphasis.) In one month, the electronic monitors in our five intensive care units, which track things like heart rate and oxygen level, produced more than 2.5 million alerts. It’s little wonder that health care providers have grown numb to them."

Comments: Before I read the third paragraph, I was thinking How can you blame the computer when it provided you with an alert regarding the prescribing error that you made? 

It is well known that systems that produce a high percentage of false alarms, that those alarms over time will be ignored or discounted. I consider this is a devastating indictment. We must do better.

I have been a human factors engineer and researcher for decades. One of the mantras of human factors is preventing errors. That's central to what we're about. But if the systems we help engineer generate false alarms at a rate that has our users ignoring the correct ones, then we have failed and failed miserably.

I think the problem of false alarms requires further research and commentary.


2. "... despite the problems, the evidence shows that care is better and safer with computers than without them."

Commentary: This is nice to read, but we as medical technologists need to do better. We really need to follow up on the repercussions of our technology we create when it's deployed and used in the field.


3. "Moreover, the digitization of health care promises, eventually, to be transformative. Patients who today sit in hospital beds will one day receive telemedicine-enabled care in their homes and workplaces."

Commentary: I agree. Of course that's a central theme of this blog.


4. "Big-data techniques will guide the treatment of individual patients, as well as the best ways to organize our systems of care. ... Some improvements will come with refinement of the software. Today’s health care technology has that Version 1.0 feel, and it is sure to get better.

... training students and physicians to focus on the patient despite the demands of the computers.

We also need far better collaboration between academic researchers and software developers to weed out bugs and reimagine how our work can be accomplished in a digital environment."

Commentary: Agreed again. But, I believe that technologist just can't dump these systems into the healthcare environments without significant follow-up research to insure that these systems provide or suggest the correct treatment programs and effectively monitor patients. Investment in systems like these will be cost effective and improve lives, but only if the necessary level of care and follow-up is performed.


5. "... Boeing’s top cockpit designers, who wouldn’t dream of green-lighting a new plane until they had spent thousands of hours watching pilots in simulators and on test flights. This principle of user-centered design is part of aviation’s DNA, yet has been woefully lacking in health care software design."

Commentary: All this is true. And as noted above that it would be a good idea to do more extensive research on medical systems before we deploy them to the field as well. That this is not done may be a regulatory issue that the FDA has not required the kind of rigorous research as performed in aircraft cockpit design. They should require more research in real or simulated environments. Right now, all that appears to be required is a single verification and single validation test before allowing commercialization. I think it would be valuable for regulators to require more research in real or simulated settings before allowing companies to commercialize their products.

Or, requiring more extensive follow-up research. Grant companies the right to sell their medical products on a probationary basis for (say) 1 year after receiving initial commercialization certification. During that year, the company must perform follow-up research on how their medical product performs in real environments. If there are no significant problems ... such as overly abundant number of false alarms ... then the product no longer on probation and would be considered fully certified for commercialization.
However, if significant problems emerge, the FDA could:

a) continue to keep the product in a probationary status pending correction of those problems and another year of follow-up research or

b) it could require the withdrawal of the product from sale. A product that had been withdrawn would have to go through the entire commercialization certification process just as if it were a new product before commercialization and sale would be allowed.


A final thought ... I think there's a reality in commercial aviation that is not true in medicine. If commercial aircraft killed and injured as many people as are killed and injured by medical practitioners, then the commercial aviation would come to a halt. People would refuse to fly because they perceive it to be too dangerous. But, if you're sick, then you have little choice but the clinic, ER or hospital.
