This is the 34th edition of Things & Thinks and covers quite a bit of ground on the research brief and digital health news updates. Of course, the ending is always with its own flavor, with Longread, Tweet and Chart o the Month. Happy to hear your thoughts and feedback…
Unexpected & Potentially harmful algorithmic behavior of AI systems
This study, published in The Lancet Digital Health, did not stop at validating their of a deep learning system for the detection of proximal femoral fractures but also performed an algorithmic audit. The authors noted that
- Although the model shows high performance, and does not appear to deviate from human performance in prespecified subgroups, it does still make the occasional inhuman error (eg, misdiagnosing a highly displaced fracture).
- Although the model reproduces some recognisable aspects of human practice (eg, it appears to pay attention to Shenton’s line), the visualisations nonetheless raise concerns about the regions that are not highlighted in the heatmaps.
- Saliency maps should be interpreted with caution due to known failings of these methods, but current findings together raise the concern that, despite the model performing extremely well at the task of proximal femoral fracture detection when assessed with summary statistics, the model appears to be prone to making unexpected mistakes and can behave unpredictably on cases that humans would consider simple to interpret.
Long way to interoperability
- About 42% of physicians used an EHR from one of the five market-leading developers, (Epic, Cerner, athenahealth, eClincalWorks and Allscripts), while 21% of physicians used an EHR from the sixth to 10th market-leading developers, meaning NextGen, Practice Fusion, Greenway, GE and Modernizing Medicine, and 27% used a different vendor.
- The researchers found “substantial variation” in data exchange capabilities based on practice size. Nearly half, or 44%, of solo practitioners were able to send, receive or query for information, compared to 71% of physicians in practices of four to 10 physicians and 76% of physicians in practices of more than 50 physicians. Integrating data into EHR varied by size of practice. Some 17% of solo practitioners said they were able to do so, compared to 30% of physicians in practices of four to 10 physicians and 51% of physicians in practices of greater than 50 physicians.
- According to the authors, whereas patients treated by large, integrated practices may receive all care within the organization, patients of small practice physicians are likely to receive care from physicians or healthcare organizations outside of the small practice. Physicians in small practices may, therefore, need to rely on interoperable technology to a greater extent to receive important clinical information in a timely and useable manner.
- Despite this potential value, small practice and independent physicians have been observed to adopt EHRs and engage in interoperable exchange at lower rates than other physicians
