External validation and regulation are urgently required to ensure these public facing tools are safe. There is wide variation in performance between available symptom checkers and overall performance is significantly below what would be accepted in any other medical field, though some do achieve a good level of accuracy and safety of disposition. Both diagnostic accuracy and appropriate resource recommendation varied substantially between systems. 51.0% of systems suggested additional resource utilisation above that recommended by national guidelines (range 18.0% to 61.2%). Safety of disposition advice decreased with condition urgency (being 71.8% for emergency cases vs 87.3% for non-urgent cases). Mean diagnostic accuracy of the systems was poor, with the correct diagnosis being present in the top five diagnoses on 51.0% (Range 22.2 to 84.0%). Twelve tools were identified and included. The safety of the disposition advice was assessed by comparing it with national guidelines for each vignette. System accuracy was assessed by measuring the percentage of times the correct diagnosis was a) listed first, b) within the top five diagnoses listed and c) listed at all. ![]() A standardised set of 50 clinical vignettes were developed and systematically run through each system by a non-clinical researcher. Publicly available symptom-checkers were identified. Publicly available symptom checkers for patient use. ![]() The aims of our study are firstly to investigate the diagnostic and triage performance of symptom checkers, secondly to assess their potential impact on healthcare utilisation and thirdly to investigate for variation in performance between systems. ![]()
