Persistent Disparities in Smoking Rates Among PLWH Compared to the General Population in Philadelphia, 2009-2014.

Despite reductions in smoking rates in the general population, little is known about recent smoking trends among people living with HIV (PLWH). We compared the risk for smoking and temporal trends in smoking among PLWH and the general population in the Philadelphia metropolitan area between 2009 and 2014. We used weighted logistic regression to assess the relation between HIV and smoking, and examined temporal smoking trends. The adjusted odds ratio (OR) for smoking comparing PLWH to the general population was 1.80 (95% CI 1.55-2.09) after adjusting for socio-economic, demographic, and mental health diagnosis variables. Smoking prevalence decreased in both the PLWH and general populations during the study period, and we did not observe a significant difference in rates of decline between groups (P = 0.54). Despite overall progress in smoking cessation, a disparity persisted in smoking rates between PLWH and the general population, with and without adjustment for socio-economic, demographic, and mental health variables. Further research is needed to understand the mechanisms linking HIV and tobacco use in order to inform public health efforts to reduce smoking among PLWH.

Interdisciplinary HIV Sentinel Case Review: Identifying Practices to Prevent Outbreaks in Philadelphia.

INTRODUCTION: The Ending the HIV Epidemic in the U.S. initiative considers cluster and outbreak response essential. This article describes the design, implementation, and early findings of a Philadelphia-based project to systematically assess sentinel cases among priority populations for improving public health infrastructure and preventing future outbreaks. METHODS: Sentinel HIV cases (i.e., early-stage or acute infection or molecular cluster cases) were identified among priority populations (Black and Hispanic/Latino men who have sex with men, youth aged 18-24 years, and transgender people who have sex with men). Chart abstraction and structured interview data were reviewed to determine themes and service gaps and to identify, prioritize, and implement recommendations. Interdisciplinary review teams included individuals with lived experience, frontline staff, and local agency leadership. RESULTS: Data were collected during July 2019-December 2020 and analyzed for 53 of 126 sentinel cases of HIV diagnosed since July 1, 2018. The majority were men who have sex with men (79.3%), those aged 18-24 years (67.9%), and non-Hispanic Black (67.9%). More than half received sexually transmitted infection and HIV testing ≤3 years preceding HIV diagnosis (56.6% and 54.7%, respectively), had a healthcare visit within 12 months before diagnosis (64.2%), and had no evidence of pre-exposure prophylaxis awareness (58.5%). Project recommendations effectuated actions to improve pre-exposure prophylaxis provision, integrate sexually transmitted infection and HIV testing, and educate primary care providers. CONCLUSIONS: HIV sentinel case review is a model for health departments to rapidly respond to recent transmission, identify missed HIV prevention opportunities, strengthen community partnerships, and implement programmatic and policy changes. Such efforts may prevent outbreaks and inform longer-term strategies.
