HIV Prevention Services for Hispanic/Latino Persons in THRIVE, 2015-2020.

INTRODUCTION: Hispanic/Latino men who have sex with men (MSM) and transgender women (TGW) are disproportionately affected by HIV in the U.S. This study evaluated HIV prevention services and outcomes among Hispanic/Latino MSM and TGW in the Targeted Highly Effective Interventions to Reduce the HIV Epidemic (THRIVE) demonstration project and consider lessons learned. METHODS: The authors described the THRIVE demonstration project services provided to Hispanic/Latino MSM and TGW in 7 U.S. jurisdictions from 2015 to 2020. HIV prevention service outcomes were compared between 1 site with (2,147 total participants) and 6 sites without (1,129 total participants) Hispanic/Latino-oriented pre-exposure prophylaxis clinical services, and Poisson regression was used to estimate the adjusted RR between sites and pre-exposure prophylaxis outcomes. Analyses were conducted from 2021 to 2022. RESULTS: The THRIVE demonstration project served 2,898 and 378 Hispanic/Latino MSM and TGW, respectively, with 2,519 MSM (87%) and 320 TGW (85%) receiving ≥1 HIV screening test. Among 2,002 MSM and 178 TGW eligible for pre-exposure prophylaxis, 1,011 (50%) MSM and 98 (55%) TGW received pre-exposure prophylaxis prescriptions, respectively. MSM and TGW were each 2.0 times more likely to be linked to pre-exposure prophylaxis (95% CI=1.4, 2.9 and 95% CI=1.2, 3.6, respectively) and 1.6 and 2.1 times more likely to be prescribed pre-exposure prophylaxis (95% CI=1.1, 2.2 and 95% CI=1.1, 4.1), respectively, at the site providing Hispanic/Latino-oriented pre-exposure prophylaxis clinical services than at other sites and adjusted for age group. CONCLUSIONS: The THRIVE demonstration project delivered comprehensive HIV prevention services to Hispanic/Latino MSM and TGW. Hispanic/Latino-oriented clinical settings may improve HIV prevention service delivery to persons in Hispanic/Latino communities.

Congenital syphilis investigation processes and timing in Louisiana.

BACKGROUND: Congenital syphilis (CS) is a potentially life-threatening yet preventable infection. State and local public health jurisdictions conduct investigations of possible CS cases to determine case status and to inform public health prevention efforts. These investigations occur when jurisdictions receive positive syphilis test results from pregnant women or from infants. METHODS: We extracted data from Louisiana's electronic case management system for 328 infants investigated as possible CS cases in 2010 to 2011. Using date stamps from the case management system, we described CS investigations in terms of processes and timing. RESULTS: Eighty-seven investigations were prompted by positive test results from women who were known to be pregnant by the health jurisdiction, and 241 investigations were prompted by positive syphilis test results from infants. Overall, investigations required a median of 101 days to complete, although 25% were complete within 36 days. Investigations prompted by positive test results from infants required a median of 135 days to complete, and those prompted by positive test results from pregnant women required a median of 41 days. CONCLUSIONS: Three times as many CS investigations began with reported positive syphilis test results from infants as from pregnant women, and these investigations required more time to complete. When CS investigations begin after an infant's birth, the opportunity to ensure that women are treated during pregnancy is missed, and surveillance data cannot inform prevention efforts on a timely basis. Consistently ascertaining pregnancy status among women whose positive syphilis test results are reported to public health jurisdictions could help to assure timely CS prevention efforts.

Challenges in congenital syphilis surveillance: how are congenital syphilis investigations classified?

BACKGROUND: Congenital syphilis is a serious, preventable, and nationally notifiable disease. Despite the existence of a surveillance case definition, congenital syphilis is sometimes classified differently using an algorithm on the Centers for Disease Control and Prevention's case reporting form. METHODS: We reviewed Louisiana's congenital syphilis electronic reporting system for investigations of infants born from January 2010 to October 2011, abstracted data required for classification, and applied the surveillance definition and the algorithm. We calculated the sensitivities and specificities of the algorithm and Louisiana's classification using the surveillance definition as the surveillance gold standard. RESULTS: Among 349 congenital syphilis investigations, the surveillance definition identified 62 cases. The algorithm had a sensitivity of 91.9% and a specificity of 64.1%. Louisiana's classification had a sensitivity of 50% and a specificity of 91.3% compared with the surveillance definition. CONCLUSIONS: The differences between the algorithm and the surveillance definition led to misclassification of congenital syphilis cases. The algorithm should match the surveillance definition. Other state and local health departments should assure that their reported cases meet the surveillance definition.

Enhanced Collection of Laboratory Data in HIV Surveillance Among 5 States with Confidential Name-based HIV Infection Reporting, 2005-2006.

Laboratory data reported through HIV surveillance can provide information about disease severity and linkage to care; however these measures are only as accurate as the quality and completeness of data reported. Using data from five states that implemented enhanced collection of laboratory data in HIV surveillance from 2005-2006, we determined completeness of reporting, stage of disease at diagnosis, the most common opportunistic illnesses (OI) at diagnosis, and linkage to medical care. Methods to enhance laboratory reporting included increasing active surveillance efforts, identifying laboratories not reporting to HIV surveillance, increasing electronic reporting, and using laboratory results from auxiliary databases. Of 3,065 persons ≥13 years of age diagnosed with HIV, 35.5% were diagnosed with stage 3 (AIDS) and 37.7% progressed to stage 3 within 12-months after diagnosis. Overall, 78.5% were linked to care within 3 months; however, a higher proportion of persons with ≥1 CD4 or viral load test was found among whites compared with blacks/African Americans (82.1% vs 73.6%, p<0.001). Few (12.3%) had an OI within 3 months of diagnosis. The completeness of laboratory data collected through surveillance was improved with enhanced reporting and provided a more accurate picture of stage of disease and gaps in linkage to care. Additional interventions are needed to meet the goals of the National HIV/AIDS Strategy on linkage to care and the reduction of HIV-related disparities.

Estimating the return of persons living with HIV/AIDS to New Orleans: methods for conducting disease surveillance in the wake of a natural disaster.

Hurricane Katrina disrupted HIV/AIDS surveillance by invalidating the New Orleans, La, surveillance and population data on persons living with HIV/AIDS. We describe 2 methods--population return and HIV surveillance data--to estimate the return of the infected population to New Orleans. It is estimated that 58% to 64% of 7068 persons living with HIV/AIDS returned by summer 2006. Although developed for HIV planning, these methods could be used with other disease surveillance programs.
