Improvement and disparities in sustained viral suppression among people with HIV in New York City, 2014–2023
Sustained viral suppression (SVS) supports the health of people with HIV (PWH). We conducted a serial cross-sectional analysis using New York City (NYC) HIV registry data. The proportion of PWH with SVS increased from 67.4% in 2014 to 77.9% in 2023 with an annual percentage change (APC) of 2.1% (95% confidence interval [CI]: 1.8, 2.5) in 2014-2020 and 0.5% (95% CI: -0.9, 2.0) in 2020-2023. Among men, the proportion increased from 68.9% in 2014 to…

Survival Among New Yorkers with HIV from 1981 to 2017
Calculating Age-Standardized Death Rates Among People With HIV Comparable Across Jurisdictions and Over Time
The Centers for Disease Control and Prevention (CDC) and local health jurisdictions have been using HIV surveillance data to monitor mortality among people with HIV in the United States with age-standardized death rates, but the principles of age standardization have not been consistently followed, making age standardization lose its purpose—comparison over time, across jurisdictions, or by other characteristics. We review the current practices o…
Neighborhood social cohesion and viral suppression after HIV diagnosis
Social cohesion has varying effects on health. We investigated the association of perceived neighborhood social cohesion with HIV viral suppression using individual-level data from the New York City HIV registry and surveillance-based interviews ( n = 92). Suppression was achieved within 12 months of HIV diagnosis by 60 percent of persons perceiving low cohesion and 71 percent of those perceiving high ( p = 0.31). Controlling for demographic and …
An expanded HIV screening strategy in the Emergency Department fails to identify most patients with undiagnosed infection
Screening for HIV in Emergency Departments (EDs) is recommended to address the problem of undiagnosed HIV. Serosurveys are an important method for estimating the prevalence of undiagnosed HIV and can provide insight into the effectiveness of an HIV screening strategy. We performed a blinded serosurvey in an ED offering non-targeted HIV screening to determine the proportion of patients with undiagnosed HIV who were diagnosed during their visit. Th…
Healthcare facility characteristics associated with achievement and maintenance of HIV viral suppression among persons newly diagnosed with HIV in New York City
Health care facility characteristics have been shown to influence intermediary health outcomes among persons with HIV, but few longitudinal studies of suppression have included these characteristics. We studied the association of these characteristics with the achievement and maintenance of HIV viral suppression among New York City (NYC) residents aged 13 years and older newly diagnosed with HIV between 2006 and 2012. The NYC HIV surveillance reg…
Reduction in Gaps in High CD4 Count and Viral Suppression Between Transgender and Cisgender Persons Living With HIV in New York City, 2007–2016
Objectives. To compare trends in HIV outcomes for cisgender and transgender persons living with HIV (PLWH) in New York City. Methods. We used HIV surveillance data for the analysis. We based CD4 count on the last measurement in a calendar year and defined viral suppression as the last viral load being less than or equal to 200 copies per milliliter in the calendar year. Results. The estimated number of PLWH increased from 73 415 in 2007 to 83 299…
Persons living with diagnosed HIV in New York City
Using NYC HIV surveillance data, we estimated the annual median age of persons living with diagnosed HIV (PLWDH) and the proportion of PLWDH over 50 years old in NYC between 2008 and 2015, and described the characteristics, retention in care and viral suppression status among PLWDH in NYC in 2015, by age (<50 vs. ≥50 years old). The median age of PLWDH in NYC increased from 46.4 years (interquartile range [IQR]: 39.4, 53.2) in 2008 to 50.2 years …
Undiagnosed HIV and HCV Infection in a New York City Emergency Department, 2015
Objectives. To measure undiagnosed HIV and HCV in a New York City emergency department (ED). Methods. We conducted a blinded cross-sectional serosurvey with remnant serum from specimens originally drawn for clinical indications in the ED. Serum was deduplicated and matched to (1) the hospital’s electronic medical record and (2) the New York City HIV and HCV surveillance registries for evidence of previous diagnosis before being deidentified and t…

HIV Diagnoses and Care Among Transgender Persons and Comparison With Men Who Have Sex With Men
Objectives. We measured HIV care outcomes of transgender persons, who have high HIV infection rates but are rarely distinguished from men who have sex with men (MSM) in HIV surveillance systems. Methods. New York City’s surveillance registry includes HIV diagnoses since 2000 and HIV laboratory test results for transgender persons since 2005. We determined immunological status at diagnosis, delayed linkage to care, and nonachievement of viral supp…
The high proportion of late HIV diagnoses in the USA is likely to stay
A static model of undiagnosed and diagnosed HIV infections by year of infection and year of diagnosis was constructed to examine the impact of changes in HIV case-finding and HIV incidence on the proportion of late diagnoses. With no changes in HIV case-finding or incidence, the proportion of late diagnoses in the USA would remain stable at the 2010 level, 32.0%; with a 10% increase in HIV case-finding and no changes in HIV incidence, the estimat…
Linkage and retention in care and the time to HIV viral suppression and viral rebound – New York City
The success of antiretroviral therapy (ART) as treatment for the individual patient and as prevention requires the achievment and maintenance of human immunodeficiency virus (HIV) viral suppression. Linkage to and retention in care are required for access to ART. We describe the impact of care on viral suppression using routinely reported surveillance data. We included New York City residents ≥13 years of age, diagnosed with HIV/AIDS from 1 July …
