Socio-ecological and pharmacy-level factors associated with buprenorphine stocking at pharmacies in New York City.

BACKGROUND: Research is lacking on community and pharmacy-level factors that are associated with stocking buprenorphine. To address these gaps, this study applied a socio-ecological framework to estimate the association between community- and pharmacy-level factors and buprenorphine stocking among a sample of pharmacies in New York City. METHODS: A telephone survey recruitment strategy was used to administer surveys to 662 pharmacies on the New York City Naloxone Standing Order Pharmacy list in 2018. The survey assessed pharmacy-level factors of private spaces to consult with pharmacists, type of pharmacy (chain/independent), size of pharmacy, having buprenorphine in stock and being open on nights and weekends. Socio-ecological variables drawn from census tract and public health data consisted of racial and ethnic composition, rates of poverty, rates of people without insurance, and rates of overdose. Mixed effects logistic regression estimated odds ratios (OR) of carrying buprenorphine in stock after adjusting for socio-ecological and pharmacy-level factors. RESULTS: Fewer than half of the pharmacies reported having buprenorphine in stock (43.81% n = 290). Logistic regression analyses indicate that several pharmacy-level factors - the number of private spaces (aOR=1.67 95% CI=1.20, 2.32 p=.002), large size of the pharmacy (aOR=1.52 95% CI=1.04, 2.22, p=.032), having naloxone in stock (aOR=1.54, 95%CI=1.03, 2.32 p=.037), as well as neighborhood-level factors of higher rates of poverty (aOR=2.07 95%CI=1.07, 4.02 p<.001) and higher rates of uninsured residents were associated with carrying buprenorphine (aOR=0.23 95%CI=0.14,.38). CONCLUSIONS: Using a socio-ecological framework, this study identified inequities in pharmacy stocking of buprenorphine by neighborhood rates of health insurance. At the pharmacy level, increasing private spaces for consultation and encouraging co-stocking of naloxone with buprenorphine stocking may reduce inequalities in buprenorphine availability.

Socio-ecological and pharmacy-level factors associated with naloxone stocking at standing-order naloxone pharmacies in New York City.

BACKGROUND: Research on socio-ecological factors that may impede or facilitate access to naloxone in pharmacies remains limited. This study investigated associations between socio-ecological factors, pharmacy participation in the naloxone cost assistance program (NCAP), pharmacy characteristics and having naloxone in stock among pharmacies in New York City. METHODS: Phone interviews were conducted with 662 pharmacies selected from the New York City Naloxone Standing Order List. Multi-level generalized linear modeling estimated associations between neighborhood racial and ethnic composition, poverty rates, overdose fatality rates, pharmacy participation in N-CAP, having private physical spaces within the pharmacy, knowledge of where to refer people to obtain naloxone and adjusted relative risk (aRR) that the pharmacy would have naloxone in stock. RESULTS: Findings from this study supported several of the hypotheses. Greater neighborhood poverty was associated with a lower likelihood of carrying naloxone compared to neighborhoods with less poverty (aRR = .79, CI95 % = .69, .90, p < .001). Pharmacies that provided a private window for consultations (aRR = 1.34, CI95 % = 1.19, 1.51, p < .001), a private room (aRR = 1.42, CI95 % = 1.30, 1.56, p < .001), and a private area (aRR = 1.42, CI95 % = 1.30, 1.56, p < .001) were associated with a higher likelihood of carrying naloxone compared than those that did not. CONCLUSIONS: Findings from this study suggest that community-level socioeconomic marginalization is a contributor to disparities in naloxone availability among pharmacies in New York City. Findings support harm reduction interventions tailored to the built environment of pharmacies that respect privacy to those seeking naloxone.
