Evaluating the quality of asynchronously versus synchronously delivered virtual care: Differences in rates of reported medication side effects by patients on a direct-to-consumer telehealth platform (Preprint)
BACKGROUND End-to-end asynchronous health care encounters are becoming an increasingly mainstream form of telehealth. Unlike synchronous telehealth, policy makers and other key health care stakeholders have been hesitant to fully embrace the fully asynchronous modality, especially in the context of direct-to-consumer (DTC) platforms where encounters are patient-initiated and there is no pre-established relationship with their provider. This hesitation is compounded by limited research comparing outcomes between asynchronous and synchronous care, especially in the DTC context. OBJECTIVE The purpose of this study is to explore whether entirely asynchronous care leads to different patient outcomes in the form of medication-related adverse events when compared to synchronous virtual care METHODS Using 10,000 randomly sampled patient records from a prominent, U.S. based DTC platform, we analyzed rates of patient-reported side effects from commonly prescribed medications and compared these rates across modalities of treatment RESULTS Fully end-to-end asynchronous care resulted in lower but nonsignificant rates of reported drug-related side effects compared to synchronous treatment. CONCLUSIONS In some circumstances, fully asynchronous care may not create unsafe prescribing conditions when compared to synchronous care. More research is needed to evaluate the safety of asynchronous care across a wider set of circumstances and measures.
