Studies revealed that there are various determinants of mortality among HIV positives after ART initiation.These determinants are so variable with context and dynamic across time with the advancement of cares and treatments. In this study we tried to identify determinants of mortality among HIV positives after initiating ART. A retrospective cohort study was conducted among 416 ART attendees enrolled between July 2005 to January 2012 in Nekemte Referral Hospital, Western Ethiopia. Actuarial table was used to estimate survival of patients after ART initiation and log rank test was used to compare the survival curves. Cox proportional-hazard regression was applied to determine the independent determinants of time to death. The estimated mortality was 4%, 5%, 6%, 7%, and 7 % at 6, 12, 24, 36 and 48 months respectively with mortality incidence density of 1.89 deaths per 100 person years (95 % CI 1.74, 3.62). Forty years and above AHR = 3.055 (95 % CI 1.292, 7.223), low baseline hemoglobin level (AHR = 0.523 (95% CI.335, 0.816)), and poor ART adherence (AHR 27.848 (95 % CI 8.928, 86.8)) were found to be an independent determinants of mortality. These determinants of mortality have to be taken into account to enhance better clinical outcomes of ART attendees. 1
