Background: Improving the safety of prescribed opioids in clinical settings is a national priority. While co-prescribing naloxone is increasingly recommended, there is little understanding of the optimal way to implement this practice.
Methods: We developed and delivered an academic detailing intervention to 40 randomly selected opioid-prescribing primary care providers in San Francisco from February to May 2015. Process outcomes were tracked and included provider demographics, number and type of contact attempts, reason for refusal (if applicable), name of detailer, duration of intervention, topics covered, provider concerns, and follow-up plan. Outcome evaluation included changes in the rate of naloxone prescriptions 4 months before and after academic detailing by provider based on de-identified Medi-Cal claims data. Using a difference-in-differences approach, we developed a negative binomial regression model to compare changes in naloxone prescribing to Medi-Cal patients between providers that did and did not receive the intervention.
Results: Eighty-three percent of 48 providers contacted accepted the intervention after a mean of 2.6 contacts. Detailing lasted a mean of 28 minutes (range 5-60 minutes) and most frequently covered indications for naloxone, examples of naloxone prescriptions, language to use with patients, and pharmacy outreach. Those who received the academic detailing had a significantly greater increase in naloxone prescriptions compared to those who did not receive the intervention (IRR=11.0, 95%CI=1.8-67.8, P=.010).
Conclusions: Academic detailing addressing opioid safety and naloxone prescribing was well-received by primary care providers and associated with an increase in naloxone prescriptions filled by Medi-Cal patients.
