Abstract: Liberal prescription of opioids is widely believed to have contributed to the ongoing epidemic of opioid misuse and related harms within the United States and elsewhere. Policies aimed at curbing the epidemic have focused on encouraging providers to adopt stricter opioid prescribing behaviors. However, the extent to which the association between providers' opioid prescribing behaviors and their patients' opioid use reflects a causal influence of behavior versus patient-provider sorting is unclear. Using Medicaid claims data for three states from 2016-2021, we use provider exits from Medicaid to evaluate how enrollees with chronic pain are affected by a switch to a lower- or higher-prescribing provider. We find that among patients with prior opioid use, switching to lower intensity physicians leads to as much as a 75% decrease in opioid use, with evidence of increased hospitalizations. While we observe a 15% increase in opioid use among opioid-naive enrollees who switch to more intensely prescribing providers, the health effects are less clear. Our findings are similar when using an instrumental variables approach to correct for the potential endogeneity of the destination provider's prescribing intensity.
