RT Journal Article SR Electronic T1 How machine learning is embedded to support clinician decision making: an analysis of FDA-approved medical devices JF BMJ Health & Care Informatics JO BMJ Health Care Inform FD BMJ Publishing Group Ltd SP e100301 DO 10.1136/bmjhci-2020-100301 VO 28 IS 1 A1 David Lyell A1 Enrico Coiera A1 Jessica Chen A1 Parina Shah A1 Farah Magrabi YR 2021 UL http://informatics.bmj.com/content/28/1/e100301.abstract AB Objective To examine how and to what extent medical devices using machine learning (ML) support clinician decision making.Methods We searched for medical devices that were (1) approved by the US Food and Drug Administration (FDA) up till February 2020; (2) intended for use by clinicians; (3) in clinical tasks or decisions and (4) used ML. Descriptive information about the clinical task, device task, device input and output, and ML method were extracted. The stage of human information processing automated by ML-based devices and level of autonomy were assessed.Results Of 137 candidates, 59 FDA approvals for 49 unique devices were included. Most approvals (n=51) were since 2018. Devices commonly assisted with diagnostic (n=35) and triage (n=10) tasks. Twenty-three devices were assistive, providing decision support but left clinicians to make important decisions including diagnosis. Twelve automated the provision of information (autonomous information), such as quantification of heart ejection fraction, while 14 automatically provided task decisions like triaging the reading of scans according to suspected findings of stroke (autonomous decisions). Stages of human information processing most automated by devices were information analysis, (n=14) providing information as an input into clinician decision making, and decision selection (n=29), where devices provide a decision.Conclusion Leveraging the benefits of ML algorithms to support clinicians while mitigating risks, requires a solid relationship between clinician and ML-based devices. Such relationships must be carefully designed, considering how algorithms are embedded in devices, the tasks supported, information provided and clinicians’ interactions with them.All data relevant to the study are included in the article or uploaded as online supplemental information.
