Background: Linkage to care is a critical step for achieving HIV viral suppression and improving outcomes in newly diagnosed individuals. An unexpectedly high number of patients who have undiagnosed HIV or ineffective viral suppression are identified upon admission to acute care. This study aims to understand factors that may be associated with lack of viral suppression for patients who are newly diagnosed at admission.

Methods: Patients with HIV, admitted to one of our eight acute care facilities were identified (n=1,632) from medical records. Of these, 94 were newly diagnosed and 1,538 had a prior diagnosis of HIV. Factors that may impact the viral suppression status (<200 copies/mL) prior to admission were examined. Median income and percentage of individuals living below poverty were inferred from the American Community Survey (U.S. Census) data based on a patient’s zipcode. All other factors were extracted from the medical record at the time of admission. Chi square tests and t-tests were used to compare patients who were virally suppressed to those who were not.

Results: The average age was 48 years old and 60% were male and 82% black race. Patients who presented and were not virally suppressed were more likely to be between the ages of 40-60 and of black race. Distributions of age groups and race were significantly different between those virally suppressed and those who were not suppressed at admission (p<0.05 for both). Blacks and whites between 40-60 years were more likely than other race and age groups to present at admission without viral suppression. Patients from geographic areas associated with high poverty and lower median income were less likely to be virally suppressed at admission (23.2% vs. 25.2%; p<0.05 for poverty and $41,183 vs. $43,757; p<0.05) for income.

Conclusion: These results indicate that age, race and geographically inferred income and poverty are significantly different between patients who are virally suppressed at admission and those who have a detectable viral load. Further investigation is needed to better understand how these patient-level factors, including socioeconomics, impact linkage to care as well as how best to allocate resources to better engage and retain patients in HIV care to improve their long-term outcomes.
