Diagnostic Accuracy of Web-Based COVID-19 Symptom Checkers: Comparison Study.

ABSTRACT:

Background

A large number of web-based COVID-19 symptom checkers and chatbots have been developed; however, anecdotal evidence suggests that their conclusions are highly variable. To our knowledge, no study has evaluated the accuracy of COVID-19 symptom checkers in a statistically rigorous manner.

Objective

The aim of this study is to evaluate and compare the diagnostic accuracies of web-based COVID-19 symptom checkers.

Methods

We identified 10 web-based COVID-19 symptom checkers, all of which were included in the study. We evaluated the COVID-19 symptom checkers by assessing 50 COVID-19 case reports alongside 410 non-COVID-19 control cases. A bootstrapping method was used to counter the unbalanced sample sizes and obtain confidence intervals (CIs). Results are report
