Integrated Hypertension and HIV Care Cascades in an HIV Treatment Program in Eastern Uganda: A Retrospective Cohort Study

Background: Persons living with HIV (PLHIV) are at increased risk of cardiovascular disease. Integration of services for hypertension (HTN), the primary cardiovascular disease risk factor, into HIV care programs is recommended in Uganda, though, uptake has been limited. We sought to compare the care cascades for HTN and HIV within an HIV program in Eastern Uganda. Methods: We conducted a retrospective cohort study of all PLHIV enrolled in 3 HIV clinics between 2014 and 2017. We determined the proportion of patients in the following cascade steps over 12 months: Screened, Diagnosed, Initiated on treatment, Retained, Monitored, and Controlled. Cascades were analyzed using descriptive statistics and compared using χ2 and t tests. Results: Of 1649 enrolled patients, 98.5% were initiated on HIV treatment, of whom 70.7% were retained in care, 100% had viral load monitoring, and 90.3% achieved control (viral suppression). Four hundred fifty-six (27.7%) participants were screened for HTN, of whom 46.9% were diagnosed, 88.1% were initiated on treatment, 57.3% were retained in care, 82.7% were monitored, and 24.3% achieved blood pressure control. There were no differences in any HIV cascade step between participants with HIV alone and those with both conditions. Conclusions: The HIV care cascade approached global targets, whereas the parallel HTN care cascade demonstrated notable quality gaps. Management of HTN within this cohort did not negatively impact HIV care. Our findings suggest that models of integration should focus on screening PLHIV for HTN and retention and control of those diagnosed to fully leverage the successes of HIV programs.
