Provider Continuity in the Prescribing of Buprenorphine/Naloxone Within Medicare Part D.

Abstract：

OBJECTIVES:Efforts to improve buprenorphine access for opioid use disorder have focused on increasing the number of waivered providers. However, it is unknown how efforts to increase initial prescribing result in a sustained pool of prescribers. We examine the prevalence of year-to-year provider-level buprenorphine prescribing, and provider- and state-level factors associated with provider continuity. METHODS:Providers prescribing buprenorphine/naloxone within the Medicare Part D claims database were evaluated from 2013 to 2017 with prescriber continuity measured as prescriptions made in consecutive years from the same provider (N = 14,222 unique providers; 6670 in 2013). RESULTS:The number of providers prescribing buprenorphine/naloxone within Medicare Part D increased from 2013 to 2017. The majority of providers prescribed buprenorphine/naloxone to 10 or fewer beneficiaries. Approximately 84% of providers prescribing buprenorphine/naloxone in 1 year prescribed it in the following year. Continuous prescribing from 2013 to 2017 was 59.4%, which was 86% the rate of a comparator chronic health medication (ie, lisinopril). Survival analyses indicated that female providers (adjusted hazard ratios [AHR] = 1.30, P < 0.001) and clinical neuroscience specialties such as psychiatry (AHR = 1.21, P < 0.001) exhibited greater discontinuation rates, whereas those with higher buprenorphine/naloxone beneficiary loads (AHR = 0.50, P < 0.001) and in states with a greater increase in overdose mortality rates (AHR = 0.88, P < 0.05) showed lower discontinuation rates. CONCLUSIONS:These data support evidence that providers who begin prescribing buprenorphine continue prescribing, although short of maximum capacity. Efforts to help providers become waivered, understand the impact of overdose fatalities in their area, and prescribe to multiple patients are likely to generate an enduring positive contribution to the number of treated patients.
