Identifying barriers to emergency department-initiated buprenorphine: A spatial analysis of treatment facility access in Michigan

Disparities in Buprenorphine Administration for Opioid Use Disorder in the Emergency Department

STUDY OBJECTIVE

Although buprenorphine is an effective treatment for opioid use disorder (OUD), this treatment is often not universally provided in the emergency department (ED). We aimed to determine whether patient characteristics, particularly race and ethnicity, were associated with buprenorphine administration.

METHODS

This was a retrospective cross-sectional study of adult patients who had a positive screening result for opioid misuse in the ED at a single urban hospital. Univariate and multivariable logistic regressions were used to assess the association of patient characteristics (race, ethnicity, age, sex, insurance type, and Area Deprivation Index) with buprenorphine administration.

RESULTS

Of 1082 patients who screened positive for opioid misuse, 133 (12%) were treated with buprenorphine and 949 (88%) were not. Despite representing over half the patient sample, Black patients (n = 682) were less likely than White patients (n = 310) to be treated with buprenorphine (multivariable: OR, 0.56; 95% CI, 0.35-0.88; P = 0.023). Age, sex, insurance type, ethnicity, and Area Deprivation Index were not associated with buprenorphine administration.

CONCLUSIONS

Patient race was associated with buprenorphine administration, even after controlling for multiple other social determinants of health. These data suggest racial disparities in care that should be investigated through further research to optimize equitable administration of buprenorphine.

A National Survey of Pediatric Emergency Medicine Clinicians' Comfort Level, Beliefs, and Experiences With Initiating Buprenorphine in the Emergency Department

INTRODUCTION

The prevalence of opioid use disorder (OUD) among adolescents has seen an alarming rise, prompting an exploration of the utilization of buprenorphine as a treatment modality. This study aimed to understand the perceptions, experiences, and comfort levels of pediatric emergency medicine (PEM) clinicians in initiating medication-assisted treatment (MAT) for pediatric patients presenting with OUD in emergency departments.

METHODS

Utilizing a cross-sectional survey design, data from 110 respondents were collected from a potential participant pool of 3062 for a response rate of 3.6%. The survey assessed demographics, clinical encounters, comfort levels, and opinions concerning the use of buprenorphine in the pediatric emergency setting.

RESULTS

Only 3.6% of respondents frequently evaluated and treated opioid withdrawal in the ED. A significant majority, 87.3%, indicated they had never prescribed buprenorphine for patients under 18 in the ED. While 53% of clinicians believed in initiating buprenorphine for adolescents with OUD in the ED, 33.6% expressed feeling "very uncomfortable" with the initiation process. Training in MAT appeared to influence attitudes and comfort levels significantly.

CONCLUSIONS

In this convenience sample survey with a 3.6% response rate, we found that a pronounced discomfort exists among PEM clinicians in initiating MAT, predominantly rooted in a lack of experience. Addressing this barrier through comprehensive training, developing evidence-based protocols, and fostering interdisciplinary collaboration is imperative to ensure optimal care for adolescents with OUD in emergency settings.

Mapping the Way to Good Health: The Interdisciplinary Challenges of Geographers in Medical Research

Geography has an important role to play in shaping the direction of medical research. In particular, its tools and theory provide essential understanding to the impacts of place on health behaviors and outcomes. Understanding some of its evolution-particularly into the subfield of medical geography-is therefore useful both for geographers and medical researchers. In this paper, we present some of the debates that geographers have grappled with, the growth of GIS (particularly in the context of medical research), some important methodological considerations that geographers help center, and some recommendations for future work at this nexus. Throughout, we speak from the perspective of geographers who have worked nearly exclusively in the health sciences since obtaining our PhDs.

Factors associated with naloxone availability and dispensing through Michigan's pharmacy standing order

Background: Pharmacy standing order policies allow pharmacists to dispense naloxone, thereby increasing access to naloxone. Objectives: To describe pharmacy standing order participation and associations of pharmacy and community characteristics that predict naloxone availability and dispensing across eight counties in Michigan. Methods: We conducted a telephone survey of 662 standing order pharmacies with a response rate of 81% (n = 539). Pharmacies were linked with census tract-level demographics, overdose fatality rates, and dispensing data. County maps were created to visualize pharmacy locations relative to fatality rates. Regression models analyzed associations between pharmacy type, neighborhood characteristics, fatality rates, and these outcomes: naloxone availability, having ever dispensed naloxone, and counts of naloxone dispensed. Results: The prevalence of standing order pharmacies was 54% (n = 662/1231). Maps revealed areas with higher fatality rates had fewer pharmacies participating in the standing order or lacked any pharmacy access. Among standing order pharmacies surveyed, 85% (n = 458/539) had naloxone available and 82% had ever dispensed (n = 333/406). The mean out-of-pocket cost of Narcan_® was $127.77 (SD: 23.93). National chains were more likely than regional chains to stock naloxone (AOR = 3.75, 95%CI = 1.77, 7.93) and to have ever dispensed naloxone (AOR 3.02, 95%CI = 1.21,7.57). Higher volume of naloxone dispensed was associated in neighborhoods with greater proportions of public health insurance (IRR = 1.38, 95%CI = 1.21, 1.58) and populations under 44 years old (IRR = 1.24, 95%CI = 1.04, 1.48). There was no association with neighborhood overdose fatality rates or race in regression models. Conclusion: As deaths from the opioid epidemic continue to escalate, efforts to expand naloxone access through greater standing order pharmacy participation are warranted.
