Racialized environments and syringe services program implementation: County-level factors.

OBJECTIVE: Racialized health inequities in substance use-related harms might emerge from differential access to syringe service programs (SSPs). To explore this, we examined the association between county-level racialized environments, other factors, and (1) SSP presence, and (2) per capita syringe and (3) naloxone distribution. METHODS: 2021 US National Survey of SSP data (n=295/412;72 % response rate) was used to identify SSP presence and the sum of syringes and naloxone doses distributed in 2020 by county. Study measures included racial residential segregation (RRS; i.e., divergence and dissimilarity indexes for Black:Non-Hispanic White & Hispanic:Non-Hispanic White) and covariates (i.e., demographic proportions, urban/suburban/rural classifications, 2020 US presidential Republican vote share, and overdose mortality from 2019). We used logit Generalized Estimating Equations to determine factors associated with county-level SSP presence, and zero inflated negative binomial regression models to determine factors associated with per capita syringe and naloxone distribution. RESULTS: SSPs were reported in 9 % (283/3106) of US counties. SSP presence was associated with higher divergence and dissimilarity indexes, urban and suburban counties, higher opioid overdose mortality, and lower 2020 Republican presidential vote share. Per capita syringes distributed was associated with lower RRS (divergence and Hispanic:White dissimilarity), lower racially minoritized population proportions and rural counties, while per capita naloxone distribution was associated with lower Hispanic and "other" population proportions, and rural counties. CONCLUSIONS: Racialized environments are associated with SSP presence but not the scope of those programs. Preventing HIV and HCV outbreaks, and overdose deaths requires addressing community level factors that influence SSP implementation and accessibility.

Provisional Entrants, Exemptions, and Kindergarteners Up-to-Date on Vaccination Before and After a Regulatory Change in Pennsylvania, 2015-2019.

OBJECTIVES: Before the 2017-2018 school year, Pennsylvania shortened the grace period for provisional entrants-kindergarteners who are not up-to-date on vaccination and do not have medical or nonmedical exemption-from 8 months to 5 days. We analyzed the impact of this change on school-entry vaccination status. METHODS: Using data from the Pennsylvania Department of Health for school years 2015-2016 through 2018-2019, we examined state-level trends in Pennsylvania kindergarteners' vaccination status, including the percentage who were up-to-date on each required vaccine, provisionally enrolled, medically exempted from vaccination, and nonmedically exempted from vaccination. Using the Spearman correlation coefficient, we assessed associations at the school level among changes in kindergarteners' vaccination status after the grace period was shortened. RESULTS: From 2016-2017 to 2017-2018, the provisional entrance rate of kindergarteners in Pennsylvania decreased substantially after the change in the grace period (from 8.1% to 2.2%), the medical exemption rate remained stable, and the nonmedical exemption rate increased slightly (from 1.8% to 2.5%). The percentage of kindergarteners up-to-date on required vaccines increased or remained stable across the study period except for polio, which decreased from 97.9% in 2015-2016 to 96.2% in 2018-2019. The change in provisional entrance rate was negatively associated with change in kindergarteners up-to-date on required vaccines (ρ range, -0.30 to -0.70) but not with change in medical or nonmedical exemptions (ρ range, -0.01 to -0.08). CONCLUSIONS: Efforts to reduce provisional entrants may increase the percentage of kindergarteners up-to-date on vaccinations at school entry without a corresponding increase in exemptions.

Students Provisionally Enrolled Due to Vaccination Requirements: Variation in State Laws and Rates.

This research examined the laws and regulations surrounding provisional enrollment in schools across the United States. Provisional enrollment refers to children who have started, but not completed, their required vaccinations and are allowed to attend school while completing their vaccinations. We found that nearly all states have laws regarding provisional enrollment, with 5 essential components to compare the laws including vaccine- and dose-specific requirements, type of personnel permitted to authorize, length of time that the children have to become up to date on their vaccinations (grace period), follow-up procedures, and consequences for noncompliance. In addition, we found that the percentage of provisionally enrolled kindergarteners varied greatly from state to state, with some states having less than 1% of provisionally enrolled kindergarteners and others having more than 8% between school years 2015-2016 and 2020-2021. We suggest that reducing the number of provisional entrants could be an alternative intervention to increase vaccination coverage.
