RESUMEN
BACKGROUND: The spectrum and incidence of influenza-associated neuropsychiatric complications are not well-characterized. The objective of this study was to define the incidence of specific neurologic and psychiatric complications associated with influenza in children and adolescents. METHODS: We assembled a retrospective cohort of children 5-17 years of age with an outpatient or emergency department International Classification of Diseases, 10th revision influenza diagnosis and enrolled in Tennessee Medicaid from 2016 to 2020. Serious neurologic or psychiatric complications requiring hospitalization were identified using a validated algorithm. Incidence rates of complications were expressed per 100,000 person-weeks of influenza and 95% confidence intervals (CIs) were reported. RESULTS: A total of 156,661 influenza encounters (median age of 9.3 years) were included. The overall incidence of neurologic complications was 30.5 (95% CI: 24.0-38.6) per 100,000 person-weeks of influenza and 1880.9 (95% CI: 971.9-3285.5) among children with an underlying neurologic comorbidity. The distribution of antiviral treatment was similar among those with and without neurologic or psychiatric complications. The overall incidence of psychiatric complications was 20.2 (95% CI: 15.1-27.0) per 100,000 person-weeks of influenza and 111.8 (95% CI: 77.9-155.5) among children with an underlying psychiatric comorbidity. Seizures (17.5, 95% CI: 12.8-23.9) were the most common neurologic complications whereas encephalitis (0.5, 95% CI: 0.02-2.5) was rare. Mood disorders (17.5, 95% CI: 12.8-23.9) were the most frequent psychiatric complications and self-harm events (0.9, 95% CI: 0.3-3.3) were the least common. DISCUSSION: Our findings reveal that the incidence of neuropsychiatric complications of influenza is overall low; however, the incidence among children with underlying neurologic or psychiatric condition is significantly higher than among children without these conditions.

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.

BACKGROUND: Antibiotic use is common for acute respiratory infections (ARIs) in children, but much of this use is inappropriate. Few studies have examined whether rurality of residence is associated with inappropriate antibiotic use. We examined whether rates of ARI-related inappropriate antibiotic use among children vary by rurality of residence. METHODS: We conducted a retrospective cohort study of children aged 2 months-5 years enrolled in Tennessee Medicaid between 2007 and 2017 and diagnosed with ARI in the outpatient setting. Study outcomes included ARI, ARI-related antibiotic use, and ARI-related inappropriate antibiotic use. Multivariable Poisson regression was used to measure associations between rurality of residence, defined by the US Census Bureau, and the rate of study outcomes, while accounting for other factors including demographics and underling comorbidities. RESULTS: A total of 805 332 children met selection criteria and contributed 1 840 048 person-years (p-y) of observation. Children residing in completely rural, mostly rural, and mostly urban counties contributed 70 369 (4%) p-y, 479 121 (26%) p-y, and 1 290 558 p-y (70%), respectively. Compared with children in mostly urban counties (238 per 1000 p-y), children in mostly rural (450 per 1000 p-y) and completely rural counties (468 per 1000 p-y) had higher rates of inappropriate antibiotic use (adjusted incidence rate ratio [aIRR] = 1.34, 95% confidence interval [CI] = 1.33-1.35 and aIRR = 1.33, 95% CI = 1.32-1.35, respectively). CONCLUSIONS: Inappropriate antibiotic use is common among young children with ARI, with higher rates in rural compared with urban counties. These differences should inform targeted outpatient antibiotic stewardship efforts.
