Telehealth abortion has become crucial in addressing surges in demand in states where abortion remains legal. The California Home Abortion by Telehealth (CHAT) study, which followed 6,034 pregnant individuals who obtained medication abortion via telehealth from three virtual clinics in 20 states and Washington, DC between April 2021 and January 2022, found that 97.7% of abortions were complete without subsequent intervention or ongoing pregnancy. Overall, 99.8% of abortions were not followed by serious adverse events. The effectiveness and safety of telehealth medication abortion were comparable to those of in-person care, with no significant differences between synchronous and asynchronous models of care. The study highlights the effectiveness and safety of telehealth abortion, which can reduce travel, cost, and stigma-related barriers, and increase convenience for patients. However, the study also noted higher rates of serious adverse events among Black patients compared to white patients, consistent with existing research on racial disparities in obstetric health outcomes. These findings provide evidence that telehealth abortion is a viable and safe alternative to in-person care, particularly in states where abortion bans have been enacted.Telehealth abortion has become crucial in addressing surges in demand in states where abortion remains legal.
