Dispensation and discontinuity among accidental overdose fatalities in the Indianapolis metropolitan area, 2016-2021
Victor, G., Ray, B., Del Pozo, B., Jaffe, K., King, A., & Huynh, P. (2023). Buprenorphine and opioid analgesics: Dispensation and discontinuity among accidental overdose fatalities in the Indianapolis metropolitan area, 2016-2021. Journal of substance use and addiction treatment, 150, Article 209053. https://doi.org/10.1016/j.josat.2023.209053
BACKGROUND: This study describes overall trends and sociodemographic disparities in buprenorphine and opioid analgesic uptake and prescribing patterns prior to fatal overdose events.
METHODS: We examined toxicology data from all accidental overdose deaths from 2016 to 2021 (N = 2682) in a large metropolitan area. These data were linked at the individual-level with a prescription drug monitoring program (PDMP).
RESULTS: Fewer than half of all deaths had any kind of PDMP record (39.9 %, n = 1070). Among those with a buprenorphine prescription, 10.6 % (n = 35) of decedents had a buprenorphine dispensation within 7 days of their death, while the majority (64.7 %, n = 214) were dispensed buprenorphine more than 30 days prior to death. Evidence existed of racial disparities among those with any buprenorphine uptake, whereby Black individuals (7.3 %, n = 24) had significantly fewer any dispensations compared to White individuals (92.7 %, n = 307). Among those with an opioid analgesic prescription, about 12.2 % (n = 90) were dispensed within 7 days of death, with the majority (68.5 %, n = 506) occurring more than 30 days prior to death. Like buprenorphine dispensations, Black individuals were prescribed a significantly smaller proportion of opioid analgesics (21.9 %, n = 162) versus White individuals (77.7 %, n = 574). Buprenorphine was detected in 78.5 % of deaths where fentanyl was present in the toxicology record, significantly greater when compared to opioid analgesics (57.5 %).
CONCLUSION: Consistent with prior research, our findings suggest prescription opioid analgesics may protect against fatal overdoses. Access to buprenorphine treatment did not keep pace with the rising lethality of the overdose crisis, and in recent years, a smaller percentage of the people at risk of fatal overdose availed themselves of MOUD preceding their death.
