Clinical outcome of admitted HIV/AIDS patients in Ethiopian tertiary care settings: A prospective cohort study

Background Acquired ImmunoDeficiency Syndrome (AIDS) related illnesses are the leading cause of death in the developing world. However; there is limited evidence regarding the incidence of mortality among admitted HIV patients in Ethiopia. Objective To determine the incidence of mortality and its predictors among admitted HIV/AIDS patients in selected tertiary care hospitals in Ethiopia. Methods A prospective cohort study involving 136 admitted HIV/AIDS patients from April 1 to August 31, 2018 was conducted in selected tertiary care hospitals in Ethiopia. Data were collected on socio-demographic, clinical characteristics, and drug related variables. Kaplan-Meier and Cox regression were used to compare survival experience of the patients and identify independent predictors of mortality. Hazard ratio was used as a measure of strength of association and p-value of <0.05 was considered to declare statistical significance. Results Of 136 patients, 80 (58.8%) were females. The overall in-hospital incidence of mortality was 2.83 per 1000 person-years. The incidences of mortality due to AIDS and non-AIDS related admissions were 6.1 [3.95, 8.67] and 5.3 [3.35, 8.23] per 1000 person-years respectively. The mean ± SD survival times among patients with AIDS and non-AIDS related illnesses were 32 ± 3.1 and 34 ± 3.3 days respectively (log rank p = 0.599). Being on non-invasive ventilation (AHR: 2.99, 95%CI; [1.24, 7.28]; p = 0.015) and having baseline body mass index (BMI) of less than 18.5 (AHR: 2.6, 95%CI; [1.03, 6.45]; p = 0.04) were independent predictors of mortality. Conclusion The study found high incidence of in-hospital mortality among admitted HIV/AIDS patients in Ethiopian tertiary care hospitals. Being on non-invasive ventilation and body mass index (BMI) of less than 18.5 were found to be independent predictors of mortality.
