Methods for jurisdictional vulnerability assessment of opioid-related outcomes.

In 2020, an estimated 2.7 million people in the US had opioid use disorder, increasing their risk of opioid-related morbidity and mortality. While jurisdictional vulnerability assessments (JVA) of opioid-related outcomes have been conducted previously in the US, there has been no unifying methodological framework. Between 2019 and 2021, we prepared ten JVAs, in collaboration with the Council of State and Territorial Epidemiologists, the Centers for Disease Control and Prevention, and state public health agencies, to evaluate the risk for opioid-involved overdose (OOD) fatalities and related consequences. Our aim is to share the framework we developed for these ten JVAs, based on our study of the work of Van Handel et al. from 2016, as well as a summary of 18 publicly available assessments of OOD or associated hepatitis C virus infection vulnerability. We developed a three-tiered framework that can be applied by jurisdictions based on the number of units of analysis (e.g., counties, ZIP Codes, census tracts): under 10 (Tier 1), 10 to <50 (Tier 2), and 50 or more (Tier 3). We calculated OOD vulnerability indices based on variable ranks, weighted variable ranks, or multivariable regressions, respectively, for the three tiers. We developed thematic maps, conducted spatial analyses, and visualized service provider locations, drive-time service areas, and service accessibility relative to OOD risk. The methodological framework and examples of our findings from several jurisdictions can be used as a foundation for future assessments and help inform policies to mitigate the impact of the opioid overdose crisis.

Evaluating Evidence-Informed Behavioral Health Models to Improve HIV Health Outcomes: Quantitative Findings from the Ryan White HIV/AIDS Program Special Projects of National Significance Black Men Who Have Sex with Men Initiative.

The Black Men who have Sex with Men (MSM) Initiative was implemented at eight sites to engage and retain Black MSM in HIV medical care and supportive services (SS) by addressing their behavioral health (BH) care needs. Using a pre-post design and generalized logistic mixed-effects models adjusting for patient-level random effects, site, baseline age, and baseline mental health status, we evaluated whether participants experienced increased postintervention attainment of (1) Awareness of HIV medical care, BH care, and SS; (2) Screening, referral, linkage, receipt, and engagement in HIV care, BH care, and SS; and (3) Retention, antiretroviral therapy prescription, and suppressed viral load. Among 758 evaluated participants, the proportion of participants who were aware of, screened for, screened positive for, and referred to BH and SS, retention in care (72% to 79%), and viral load suppression (68% to 75%) increased between baseline and postintervention. Among participants who screened positive and received BH services were statistically more likely to be linked to [OR, 1.34 (95% CI: 1.08-1.66)] and retained in [OR, 1.36 (95% CI: 1.00-1.83)] care. Among those who screened positive and received SS were statistically more likely to be retained in care [OR, 1.54 (95% CI: 1.07-2.22)]. Measures of linkage to care declined significantly during the study period, perhaps because of COVID-19 that delayed in-person care. This study suggests that interventions designed to increase utilization of BH services and SS can be effective at improving retention in care and viral load suppression among Black MSM, at least among those currently using HIV services.

Characterizing opioid-involved overdose risk in local communities: An opioid overdose vulnerability assessment across Indiana, 2017.

The objective of this initiative was to conduct a comprehensive opioid overdose vulnerability assessment in Indiana and evaluate spatial accessibility to opioid use disorder treatment, harm reduction services, and opioid response programs. We compiled 2017 county-level (n = 92) data on opioid-related and socioeconomic indicators from publicly available state and federal sources. First, we assessed the spatial distribution of opioid-related indicators in a geographic information system (GIS). Next, we used a novel regression-weighted ranking approach with mean standardized covariates and an opioid-involved overdose mortality outcome to calculate county-level vulnerability scores. Finally, we examined accessibility to opioid use disorder treatment services and opioid response programs at the census tract-level (n = 1511) using two-step floating catchment area analysis. Opioid-related emergency department visit rate, opioid-related arrest rate, chronic hepatitis C virus infection rate, opioid prescription rate, unemployment rate, and percent of female-led households were independently and positively associated with opioid-involved overdose mortality (p < 0.05). We identified high-risk counties across the rural-urban continuum and primarily in east central Indiana. We found that only one of the 19 most vulnerable counties was in the top quintile for treatment services and had naloxone provider accessibility in all of its census tracts. Findings from our vulnerability assessment provide local-level context and evidence to support and inform future public health policies and targeted interventions in Indiana in areas with high opioid overdose vulnerability and low service accessibility. Our approach can be replicated in other state and local public health jurisdictions to assess opioid-involved public health vulnerabilities.
