We describe the rate of death and identify the determinants of survival in a cohort of adults starting antiretroviral therapy (ART) in 2 hospitals in Upper West Region, Ghana. Kaplan-Meier model was used to estimate the survival probability after ART initiation and Cox proportional hazard model used to assess the relationship between baseline variables and mortality. A total of 91 clients who were initiated on ART in both hospitals participated in the study. Clients staged in the World Health Organization (WHO) clinical stage III/IV had a higher risk of mortality than those staging I/II (hazard ratio [HR] of 3.93). Hemoglobin value at baseline with a cutoff ≥12 g/dL for women (and ≥13 for men) was strongly associated with mortality in participants with an HR of 3.87 (95% confidence interval [CI]: 0.71-21.19) for severe anemia, 2.11 (95% CI: 0.45-9.93) for moderate anemia, and 0.88 (95% CI: 0.16-4.82) for mild anemia. Anemia and WHO staging were independent predictors of mortality.
