Event studies results of effect of social distancing policies on in-person office visit and telehealth utilization.

Caption: These event study figures show changes in regression-adjusted utilization of each service in the weeks before and after the county-level implementation of shelter-in-place policies. Regression models were estimated using ordinary least squares. Regression models include controls for the patient's age and gender, and fixed effects for week and county. The outcome measure is the number of patients, and all models are weighted for the total number of eligible enrollees. Standard errors are clustered at the county level.
