Quality of asynchronous webchats

Background: Prompt professional care for postpartum depression (PPD) is difficult to obtain in China. Though online consultations improve accessibility and reduce stigma, the quality of services compared to in-person consultations is unclear. Methods: Five trained, undisclosed "standardized patients" (SPs) made "asynchronous webchats" visits and in-person visits with psychiatrists. Visits were made to 85 psychiatrists who were based in 69 hospitals in ten provincial capital cities. The care between online and in-person consultations with the same psychiatrist was compared, including diagnosis, guideline adherence, and patient-centeredness. False discovery rate (FDR) was used to adjust p values. Third visits using asynchronous webchats were made to psychiatrists who offered discrepant diagnoses. Thematic content analysis was used for the discrepancies. Findings: The proportion of diagnostic accuracy was lower for online than in-person visits (76.5% [65/85] Interpretation: Online consultations using asynchronous webchats were inferior to in-person consultations, with respect to diagnostic accuracy, adherence to recommended clinical guidelines, and patient-centeredness. To fully realise the potential benefits of online consultations and to prevent safety issues, there is an urgent need for major improvement in the quality and oversight of these consultations.
