Hospitals May Turn To Algorithms To Fight Fatal Infections (scientificamerican.com)

An anonymous reader quotes a report from Scientific American: Clostridium difficile, a deadly bacterium spread by physical contact with objects or infected people, thrives in hospitals, causing 453,000 cases a year and 29,000 deaths in the United States, according to a 2015 study in the New England Journal of Medicine. Traditional methods such as monitoring hygiene and warning signs often fail to stop the disease. But what if it were possible to systematically target those most vulnerable to C-diff? Erica Shenoy, an infectious-disease specialist at Massachusetts General Hospital, and Jenna Wiens, a computer scientist and assistant professor of engineering at the University of Michigan, did just that when they created an algorithm to predict a patient's risk of developing a C-diff infection, or CDI. Using patients' vital signs and other health records, this method -- still in an experimental phase -- is something both researchers want to see integrated into hospital routines.

The CDI algorithm -- based on a form of artificial intelligence called machine learning -- is at the leading edge of a technological wave starting to hit the U.S. health care industry. After years of experimentation, machine learning's predictive powers are well-established, and it is poised to move from labs to broad real-world applications, said Zeeshan Syed, who directs Stanford University's Clinical Inference and Algorithms Program. Shenoy and Wiens' CDI algorithm analyzed a data set from 374,000 inpatient admissions to Massachusetts General Hospital and the University of Michigan Health System, seeking connections between cases of CDI and the circumstances behind them. The records contained over 4,000 distinct variables. As it repeatedly analyzes this data, the ML process extracts warning signs of disease that doctors may miss -- constellations of symptoms, circumstances and details of medical history most likely to result in infection at any point in the hospital stay.

      The year in which HIPAA is still the law of the land. Your provider has been told that any communication to you must be encrypted in transit and in storage, or you have to specifically waive your rights under HIPAA to permit something different. Any exception to that has to be pretty much an already existing standard. Since penalties can be $50,000 per violation, most providers do take that pretty seriously in realms where they can easily be caught. That said, groups can indeed send out texts reminding you of your appointment, so there is no legal barrier to sending you a note that they're running behind.

      The actual reason is all you'd need is a manager who is willing to take responsibility for sending a message like that. But what will happen is, just once, three people will end up skipping their appointments with the provider, catching the clinic back up again and then some. Then the next two patients took that "we're delayed an hour" message to mean that they could take two hours off coming in for their appointments. Then when P.O.'ed physician who's trying to pack as many visits as possible into as short a time as possible (also pissed because Medicare and insurances haven't given meaningful rate increases in years because "quality"), asks nurses' aide why he or she doesn't have a patient ready and the NA says, "Well, Manager sent out a text we're being delayed...." Manager is then jacked up about stupidly not having patients waiting to be seen in sufficient quantity that provider's time is never wasted.

      Flipping that around, your physicians feel less obligation to get you in and out on your timeframe then theirs. And the entire economics of the healthcare system support the physican in this, because there is no reward to get you in and out on time and not enough momentum to make that a reality. The system rewards having you wait while the provider is never unbusy. They're getting fried enough by MACRA already.

IMO this can lead to poor sensitivity since you are working on fewer data points than IP might expect to see....Then there is the whole fact that no one wants to potentially miss a sepsis case so the home grown tools will probably err on the side of too inclusive.

      Recently we moved away from a SIRS based tool that was used by some of our sites and our informatics team spent months reviewing data from production and making adjustments before turning the actual alerting on so that the tool would be within a range that they considered acceptably greedy.

      We use Epic as our EMR and are going to turn on their Sepsis data model that came out with the most recent version of the software and compare its results with the data from our current tool and the outcome data for awhile to see if it is at least as good (hoping for better).
