Pennsylvania buprenorphine dispensing in January–October, 2019 and 2020. A Patients filling prescriptions for buprenorphine each week. B Buprenorphine-naïve patients filling prescriptions for buprenorphine. C Mean days’ supply of filled buprenorphine prescriptions. D Patients with active prescriptions for buprenorphine each week. For each figure, we used the beginning of calendar week 12 (March 22, 2020) as the transition between analysis periods (corresponding to the date Pennsylvania instituted stay-at-home orders in major counties because of COVID; 2 weeks after COVID-19 was declared an emergency in Pennsylvania; 1 week before restrictions around telehealth for medication-assisted treatment services were eased). The transition is indicated in each panel by a dotted vertical line at week 12.
