This preliminary analysis provides the first evidence that academic detailing influenced naloxone prescribing rates in a large, integrated health care system at 1 and 2 years. In addition, AD-exposed providers had a higher average difference in naloxone prescribing rate compared with AD-unexposed providers after 2 years of follow-up.
Background: Benzodiazepine use in the US Veterans Administration (VA) has been decreasing; however, a small number of veterans with posttraumatic stress disorder (PTSD) continue to receive benzodiazepine. Academic detailing, a targeted-educational outreach intervention, was implemented at VA to help reduce the disparity between existing and evidence-based practices, including the reduction in benzodiazepine use in veterans with PTSD. Since evidence to support the national implementation of academic detailing in this clinical scenario was scarce, we performed a quality improvement evaluation on academic detailing's impact on benzodiazepine use in veterans with PTSD. Methods: A retrospective cohort design was used to evaluate the impact of academic detailing on benzodiazepine prescribing in veterans with PTSD from January 1, 2016, to December 31, 2016. Providers exposed to academic detailing (AD-exposed) were compared with providers unexposed to academic detailing (AD-unexposed) using generalized estimating equations (GEEs) controlling for baseline covariates. Secondary aims evaluated academic detailing's impact on average lorazepam equivalent daily dose (LEDD), total LEDD, and benzodiazepine day supply. Results: Overall, there was a decrease in the prevalence in benzodiazepine use in veterans with PTSD from 115.5 to 103.3 per 1000 population (P < .001). However, the decrease was greater in AD-exposed providers (18.37%; P < .001) compared with AD-unexposed providers (8.74%; P < .001). In the GEE models, AD-exposed providers had greater reduction in the monthly prevalence of veterans with PTSD and a benzodiazepine prescription compared with AD-unexposed providers, by À1.30 veterans per 1000 population (95% confidence interval [CI]: À2.14, À0.46). Similar findings were reported for the benzodiazepine day supply; however, no significant differences were reported for total and average LEDD. Conclusions: Although benzodiazepine use has been decreasing in veterans with PTSD, opportunities to improve prescribing continue to exist at the VA. In this quality improvement evaluation, AD-exposed providers were associated with a greater reduction in the prevalence of veterans with PTSD and a benzodiazepine prescription compared with AD-unexposed providers.
Objectives
To assess the process and outcomes of academic detailing to enhance the Opioid Safety Initiative and the Psychotropic Drug Safety Initiative to reduce co-prescribing of opioid-benzodiazepine combinations in veterans.
Methods
A retrospective cohort design was conducted to evaluate the impact of implementing an academic detailing program on opioid-benzodiazepine co-prescribing between October 2014 through March 2019 at the U.S. Department of Veterans Affairs (VA). The primary outcome was the monthly prevalence of veterans (number per 1,000 population) who were co-prescribed opioid-benzodiazepine combination. Process measure was evaluated using implementation reach (proportion of providers who received academic detailing). Station-level analysis was performed using a linear fixed effects regression model to evaluate the rate of change in the prevalence of veterans co-prescribed opioid-benzodiazepine.
Results
Altogether 130 VA stations was included for analysis; 119 stations implemented opioid-related or benzodiazepine-related academic detailing, and 11 stations did not. Stations that had implemented academic detailing had a 33% greater monthly reduction on the opioid-benzodiazepine co-prescribing prevalence compared to stations that did not implement academic detailing (P = .036). In the linear fixed effects regression model, stations that were expected to have 100% of providers exposed to academic detailing were statistically associated with a greater decrease in the monthly prevalence of Veterans co-prescribed opioid-benzodiazepine by 4.9 veterans per 1,000 population (P < .001) compared to stations with 0% of providers exposed to academic detailing.
Conclusions
Stations that implemented academic detailing and had a higher proportion of providers who were exposed to opioid- or benzodiazepine-related academic detailing had a significant decrease in the monthly prevalence of Veterans co-prescribed opioid-benzodiazepine combinations.
