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.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.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.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.

Limited information exists about testing for HIV, HBV, and HCV among Medicaid enrollees after initiating an episode of medication treatment for opioid use disorder (MOUD), despite guidelines recommending such testing. Our objectives were to estimate testing prevalence and trends for HIV, HBV, and HCV among Medicaid enrollees initiating MOUD and examine enrollee characteristics associated with testing.We conducted a serial cross-sectional study of 505,440 initiations of MOUD from 2016 to 2019 among 361,537 Medicaid enrollees aged 12-64 years in 11 states. Measures of MOUD initiation; HIV, HBV, and HCV testing; comorbidities; and demographics were based on enrollment and claims data. Each state used Poisson regression to estimate associations between enrollee characteristics and testing prevalence within 90 days of MOUD initiation. We pooled state-level estimates to generate global estimates using random effects meta-analyses.From 2016 to 2019, testing for HIV increased from 20% to 25%, HBV from 22% to 25%, HCV from 24% to 27%, and for all three conditions from 15% to 19%. Adjusted rates of testing for all three conditions were lower among enrollees who were male (vs. non-pregnant females), living in a rural area (vs. urban area), and initiating methadone or naltrexone (vs. buprenorphine). Associations between enrollee characteristics and testing were heterogeneous across states.Among Medicaid enrollees in 11 states, testing for HIV, HBV, and HCV increased among enrollees initiating MOUD; however, approximately three-quarters of enrollees were not tested for each condition, and testing rates differed by enrollee characteristics.

Kentucky has one of the highest opioid overdose mortality rates in the United States. Accurate estimates of people with opioid use disorder (OUD) are critical to plan for the scope of interventions required to reduce overdose and opioid misuse. Commonly used household surveys are known to underestimate OUD at the state-level and do not provide county-level estimates.We performed a multi-sample capture-recapture analysis to estimate OUD prevalence in Kentucky in 2018 and 2019. We utilized four statewide datasets that were linked at the individual level: 1) Registry of Vital Statistics, 2) Emergency Medical Services (EMS), 3) Kentucky's Prescription Drug Monitoring Program (PDMP), and 4) Kentucky Medicaid. We included persons aged 18-64 years who resided in Kentucky between 2018 and 2019. We identified individuals with administrative data consistent with OUD in each of the datasets, including a fatal opioid-involved overdose (Vital Statistics), EMS runs for suspected opioid overdose, receipt of buprenorphine for OUD treatment (PDMP), or Medicaid claims for OUD. Observed and estimated counts of OUD cases and prevalence of OUD among the adult population in Kentucky.The estimated statewide OUD prevalence was 5.5 % and 5.9 % for 2018 and 2019, respectively, ranging from 1.3 % to 17.7 % across Kentucky counties. As expected, counties with the highest OUD rates were Appalachian counties (eastern area) of the state.Our analysis reveals a substantially larger proportion of KY residents have OUD than previously estimated. Our approach offers a model for states needing county-level estimates of OUD.

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.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.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.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.
