The purpose of this paper is to present evaluation results. People exiting incarceration who use opioids are at an elevated risk for overdose following release. People living with HIV (PLWH) who use drugs are also at increased overdose risk. Overdose education and naloxone distribution (OEND) is an effective community-based intervention, but few OEND programs have been evaluated in a correctional setting and none have specifically targeted PLWH.

An OEND pilot program was implemented in the Philadelphia jail from December 2017 to June 2019. OEND was provided through an HIV case management program and naloxone given at release. Participants (n = 68) were assessed for changes in overdose knowledge and beliefs in their ability to respond to an overdose from baseline to one month later while still incarcerated. Other demographic variables were assessed via publicly available records and case manager chart abstraction.

A total of 120 incarcerated PLWH were OEND trained; 68 (56.7%) were still incarcerated one month later and received post-tests. The 68-person sample was predominantly male (79.4%) and Black (64.7%). One-fifth reported heroin use, a third reported cocaine use and nearly 2/3 reported use of any illegal drug on date of arrest. Among these 68, overdose knowledge and overdose attitudes improved significantly (p = 0.002 and p < 0.001, respectively).

OEND in correctional settings is feasible and knowledge and overdose attitudes improved significantly from baseline. OEND programs should be implemented within the general population of incarcerated people but, as with PLWH, can be extended to other vulnerable populations within correctional settings, such as persons with mental health conditions and a history of homelessness.

Since the development of the COVID-19 vaccinations, questions surrounding race have been prominent in the literature on vaccine uptake. Early in the vaccine rollout, public health officials were concerned with the relatively lower rates of uptake among certain racial/ethnic minority groups. We suggest that this may also be patterned by racial/ethnic residential segregation, which previous work has demonstrated to be an important factor for both health and access to health care.

In this study, we examine county-level vaccination rates, racial/ethnic composition, and residential segregation across the U.S. We compile data from several sources, including the American Community Survey (ACS) and Centers for Disease Control (CDC) measured at the county level.

We find that just looking at the associations between racial/ethnic composition and vaccination rates, both percent Black and percent White are significant and negative, meaning that higher percentages of these groups in a county are associated with lower vaccination rates, whereas the opposite is the case for percent Latino. When we factor in segregation, as measured by the index of dissimilarity, the patterns change somewhat. Dissimilarity itself was not significant in the models across all groups, but when interacted with race/ethnic composition, it moderates the association. For both percent Black and percent White, the interaction with the Black-White dissimilarity index is significant and negative, meaning that it deepens the negative association between composition and the vaccination rate.

The analysis is only limited to county-level measures of racial/ethnic composition and vaccination rates, so we are unable to see at the individual-level who is getting vaccinated.

We find that segregation moderates the association between racial/ethnic composition and vaccination rates, suggesting that local race relations in a county helps contextualize the compositional effects of race/ethnicity.
