Changes in Outpatient Opioid Prescribing During the COVID-19 Pandemic: An Interrupted Time Series Analysis.

Objectives: Changes in health care delivery during the COVID-19 pandemic may have impacted opioid prescribing. This study evaluated the impact of restrictions on in-person care on opioid prescribing in the outpatient setting. The hypothesis was that after restrictions to in-person care were implemented, there would be a reduction in the number of chronic and non-chronic opioid prescriptions.

Methods: An interrupted time series analysis was conducted to compare the number of weekly opioid prescriptions between baseline (1/1/2019-3/14/2020), restriction (3/15/2020-6/6/2020), and reopening (6/7/2020-10/31/2020) periods at outpatient practices within a health system in Bronx, NY. Analyses were stratified by prescription type (chronic if the patient had been prescribed opioids for >90 days, or non-chronic).

Results: For , the week restrictions were implemented, there was an increase in the number of prescriptions compared to what was predicted if there had been no interruption (34.8 prescriptions, 95% CI: 8.0, 61.7). Subsequently, the weekly trend in prescribing was not different in the restriction period or in the reopening period compared to the previous time periods. For , during the restriction period, the weekly trend in prescribing decreased compared to baseline (-5.0 prescriptions/week, 95% CI: -9.0, -1.0). Subsequently, during the reopening period, the weekly trend in prescribing increased compared to the restriction period (6.4 prescriptions/week, 95% CI: 2.2, 10.7).

Conclusions: Despite abrupt restrictions on in-person care, chronic opioid prescriptions did not decrease, which is evidence that providers evolved to meet patient needs. Changes in non-chronic prescriptions are likely related to patients electing not to pursue care for acute pain or challenges with appointment availability.
