RESUMO
Development of HAART in the mid-1990's and its continued scale up has revolutionized the treatment of HIV-infected patients and led to remarkable reductions in HIV associated morbidity and mortality. However, recent studies have suggested a higher risk for early mortality in adults receiving ART in low-income countries as compared to those in high-income countries. There is dearth of data from developing countries where the burden of disease is high. The objective is to describe the burden and correlation between early vs. delayed mortality associated with HIV/AIDS in resource poor settings using data from Tanzania in East Africa. We performed a cross-sectional evaluation of routinely collected program data for 991 HIV-positive deceased adult patients who were placed on ART treatment, and died between January 1, 2007 and December 31, 2012. Data used were abstracted from records of patients who were treated at six health facilities in the Lake-zone Region of Tanzania in the timeframe. Bivariate and multivariate regression models were used to identify independent predictors of mortality and to calculate odds ratios. From the population, early deaths (within 3 months of ART initiation) occurred in 359 of the 991 cases, which represented 36.2%; while delayed deaths (after 3 months of ART initiation) occurred in 632 of 991 (63.8%). The average time to death for those who died within 3 months was 1 month compared to 22 months among those who died at > 3 months since initiation of ARV. In multivariate analysis, patients who were on WHO stage IV, had fever and cough symptoms at 6 months prior to death and patients with 0-1, 2-3, and 4-6 clinic visits had a higher risk of death in the first 3 months. Mortality among patients started on ART seems to be high. Where possible, healthcare providers should do more to vigorously monitor patients before starting them on ART for better outcomes. Additionally, public health efforts to encourage early testing and entry into treatment must be scaled up in resource poor countries to gain some lead-time and to keep the virus under control, sustain immune function, and delay the onset of opportunistic infections.
