The US Preventive Services Task Force has recommended offering preexposure prophylaxis (PrEP) to individuals who are at high risk of human immunodeficiency virus acquisition. Because PrEP treatment does not prevent bacterial sexually transmitted infections (STIs), Centers for Disease Control and Prevention treatment guidelines recommend STI screening for individuals taking PrEP every 3 to 6 months. No known studies estimate STI screening among individuals using PrEP in the US South, a geographic region with high rates of human immunodeficiency virus and bacterial STIs. Objectives: The purpose of this study was to measure sexually transmitted infection (STI) testing among Medicaid enrollees initiating preexposure prophylaxis (PrEP) to prevent human immunodeficiency virus. Secondary data are in the form of Medicaid enrollment and claims data in six states in the US South. Methods: Research partnerships in six states in the US South developed a distributed research network to accomplish study aims. Each state identified all first-time PrEP users in fiscal year 2017–2018 (combined N = 990) and measured the presence of STI testing for chlamydia, syphilis, and gonorrhea through 2019. Each state calculated the percentage of individuals with at least one STI test during 3-, 6-, and 12-month follow-up periods. Results: The proportion of first-time PrEP users that received an STI test varied by state: 37% to 67% of all of the individuals in each state who initiated PrEP received a test within the first 6 months of PrEP treatment and 50% to 77% received a test within the first 12 months. Conclusions: Although the Centers for Disease Control and Prevention recommends STI testing at least every 6 months for PrEP users, our analysis of Medicaid data suggests that STI testing occurs less frequently than recommended in populations at elevated risk of syphilis, gonorrhea, and chlamydia.

Introduction: The rates of syphilis among pregnant women and infants have increased in recent years, particularly in the U.S. South. Although state policies require prenatal syphilis testing, recent screening rates comparable across Southern states are not known. The purpose of this study is to measure syphilis screening among Medicaid enrollees with delivery in states in the U.S. South.Methods: A total of 6 state-university research partnerships in the U.S. South developed a distributed research network to analyze Medicaid claims data using a common analytic approach for enrollees with delivery in fiscal years 2017-2018 and 2018-2019 (combined N=504,943). In 2020-2021, each state calculated the percentage of enrollees with delivery with a syphilis screen test during the first trimester, third trimester, and at any point during pregnancy. Percentages for those with first-trimester enrollment were compared with the percentages of those who enrolled in Medicaid later in pregnancy.Results: Prenatal syphilis screening during pregnancy ranged from 56% to 91%. Screening was higher among those enrolled in Medicaid during the first trimester than in those enrolled later in pregnancy.Conclusions: Despite state laws requiring syphilis screening during pregnancy, screening was much lower than 100%, and states varied in syphilis screening rates among Medicaid enrollees. Findings indicate that access to Medicaid in the first trimester is associated with higher rates of syphilis screening and that efforts to improve access to screening in practice settings are needed.

Residential treatment is a key component of the opioid use disorder care continuum, but research has not measured well the differences in its use across states at the enrollee level. This cross-sectional observational study used Medicaid claims data from nine states to document the prevalence of residential treatment for opioid use disorder and to describe the characteristics of patients receiving care. For each patient characteristic, chi-square and t -tests tested for differences in the distribution between individuals who did and did not receive residential care. Among 491,071 Medicaid enrollees with opioid use disorder, 7.5 % were treated in residential facilities in 2019, though this number ranged widely (0.3–14.6 %) across states. Residential patients were more likely to be younger, non-Hispanic White, male, and living in an urban area. Although residential patients were less likely than those without residential care to be eligible for Medicaid through disability, diagnoses for comorbid conditions were more frequently observed among residential patients. Results from this large, multi-state study add context to the ongoing national conversation around opioid use disorder treatment and policy, providing a baseline for future work. • 7.5 % of Medicaid enrollees with opioid use disorder receive residential treatment. • Residential treatment prevalence varies across states, ranging from 0.3 to 14.6 %. • Residential patients tend to be younger, non-Hispanic white, male, in urban areas.

Background: Follow-up after residential treatment is considered best practice in supporting patients with opioid use disorder (OUD) in their recovery. Yet, little is known about rates of follow-up after discharge. The objective of this analysis was to measure rates of follow-up and use of medications for OUD (MOUD) after residential treatment among Medicaid enrollees in 10 states, and to understand the enrollee and episode characteristics that are associated with both outcomes.Methods: Using a distributed research network to analyze Medicaid claims data, we estimated the likelihood of 4 outcomes occurring within 7 and 30 days post-discharge from residential treatment for OUD using multinomial logit regression: no follow-up or MOUD, follow-up visit only, MOUD only, or both follow-up and MOUD. We used meta-analysis techniques to pool state-specific estimates into global estimates.Results: We identified 90,639 episodes of residential treatment for OUD for 69,017 enrollees from 2018 to 2019. We found that 62.5% and 46.9% of episodes did not receive any follow-up or MOUD at 7 days and 30 days, respectively. In adjusted analyses, co-occurring mental health conditions, longer lengths of stay, prior receipt of MOUD or behavioral health counseling, and a recent ED visit for OUD were associated with a greater likelihood of receiving follow-up treatment including MOUD after discharge.Conclusions: Forty-seven percent of residential treatment episodes for Medicaid enrollees are not followed by an outpatient visit or MOUD, and thus are not following best practices.
