Availability of medications for opioid use disorder in outpatient and inpatient pharmacies in South Florida: a secret shopper survey

Abstract

Background: Despite the proven efficacy of medications for opioid use disorder (MOUD) and recent reduction in barriers to prescribers, numerous obstacles exist for patients seeking MOUD. Prior studies have used telephone surveys to investigate pharmacy-related barriers to MOUD. We applied this methodology to evaluate inpatient and outpatient pharmacy barriers to MOUD in South Florida.

Methods: Randomly selected pharmacies in South Florida (Miami-Dade, Broward, and Palm Beach Counties) were called using a standardized script with a "secret shopper" approach until 200 successful surveys had been completed. The primary outcome was the availability of any buprenorphine products. Second, a list of all 48 acute care hospitals within the aforementioned counties was compiled, and hospitals were contacted by telephone using a second structured script.

Results: A total of 1374 outpatient pharmacies and 48 inpatient pharmacies were identified. 378 randomly selected outpatient pharmacies were contacted to accrue 200 successful calls (53% success rate). All 48 inpatient pharmacies were contacted to successfully complete 25 inpatient surveys (52%). Of the 200 outpatient pharmacies contacted, 38% had any buprenorphine available. There was a significant difference in buprenorphine availability by county, with Miami-Dade having the least availability and Palm Beach having the most availability (27% vs. 47%, respectively; p = 0.04). Of the 38% with buprenorphine available, 82% had a sufficient supply for a two-week prescription of buprenorphine 8 mg twice daily. Of the pharmacies that did not have buprenorphine, 55% would be willing to order with a median estimated time to receive an order of 2 days (IQR 1.25-3 days). Of the 25 surveyed inpatient pharmacies, 88% reported having buprenorphine on inpatient formulary, and 55% of hospitals had at least one restriction on ordering of buprenorphine beyond federal regulations.

Conclusions: The results of this study highlight significant pharmacy-related barriers to comprehensive OUD treatment across the healthcare system including both acute care hospital pharmacies and outpatient community pharmacies. Despite efforts to increase the number of MOUD providers, there still remain downstream obstacles to MOUD access.
