CUNY: How Health Care Facility Characteristics Affect HIV Viral Suppression among NYC Patients

Health care facility characteristics such as the type of clinical setting, the travel distance from the patient’s home, the support services offered, and physician experience have been shown to influence health outcomes among persons with human immunodeficiency virus (HIV), but few studies have explored how these factors influence HIV viral suppression among patients.

To test the association of these characteristics with the achievement and maintenance of HIV suppression among newly-diagnosed New York City residents, CUNY Graduate School of Public Health and Health Policy doctoral alumna Dr. Ellen Wiewel — now the director of research and evaluation at the New York City Department of Health and Mental Hygiene’s Housing Services Unit — led a study with CUNY SPH faculty. “Healthcare facility characteristics associated with achievement and maintenance of HIV viral suppression among persons newly diagnosed with HIV in New York City” was then published in the journal AIDS Care.

The researchers applied multivariable proportional hazards models to patient and facility data from the NYC HIV Surveillance Registry to compare individual achievement and maintenance of viral suppression by type of facility, patient volume, and distance from residence.

The study found that patients at facilities with higher HIV-positive caseloads achieved and maintained viral suppression the most. Facilities with small caseloads and screening/diagnosis sites may need stronger care or referral systems to help persons with HIV achieve and maintain viral suppression.

“Our analysis suggested that assisting people with HIV to attend large healthcare facilities, or supporting smaller facilities to strengthen their services or referral systems, may help end the epidemic by increasing the rates of HIV viral suppression,” said Dr. Wiewel.
