Wallace W, Chan C, Chidambaram S, et al. The diagnostic and triage accuracy of digital and online symptom checker tools: a systematic review. NPJ Digit Med. 2022;5(1). doi:10.1038/s41746-022-00667-w.
Patient use of digital and online symptom checkers is increasing, but formal validation of these tools is lacking. This systematic review identified ten studies assessing symptom checkers evaluating a variety of conditions, including infectious diseases and ophthalmic conditions. The authors concluded that the diagnostic and triage accuracy of symptom checkers varies and has low accuracy.
