- ItemOpen AccessDensity of healthcare providers and patient outcomes: evidence from a nationally representative multi-site HIV treatment program in Uganda(Public Library of Science, 2011) Bakanda, Celestin; Birungi, Josephine; Mwesigwa, Robert; Zhang, Wendy; Hagopian, Amy; Ford, Nathan; Mills, Edward JObjective We examined the association between density of healthcare providers and patient outcomes using a large nationally representative cohort of patients receiving combination antiretroviral therapy (cART) in Uganda. Design We obtained data from The AIDS Support Organization (TASO) in Uganda. Patients 18 years of age and older who initiated cART at TASO between 2004 and 2008 contributed to this analysis. The number of healthcare providers per 100 patients, the number of patients lost to follow-up per 100 person years and number of deaths per 100 person years were calculated. Spearman correlation was used to identify associations between patient loss to follow-up and mortality with the healthcare provider-patient ratios. RESULTS: We found no significant associations between the number of patients lost to follow-up and physicians ( p = 0.45), nurses ( p = 0.93), clinical officers ( p = 0.80), field officers ( p = 0.56), and healthcare providers overall ( p = 0.83). Similarly, no significant associations were observed between mortality and physicians ( p = 0.65), nurses ( p = 0.49), clinical officers ( p = 0.73), field officers ( p = 0.78), and healthcare providers overall ( p = 0.73). CONCLUSIONS: Patient outcomes, as measured by loss to follow-up and mortality, were not significantly associated with the number of doctors, nurses, clinical officers, field officers, or healthcare providers overall. This may suggest that that other factors, such as the presence of volunteer patient supporters or broader political or socioeconomic influences, may be more closely associated with outcomes of care among patients on cART in Uganda.
- ItemOpen AccessMale gender predicts mortality in a large cohort of patients receiving antiretroviral therapy in Uganda(BioMed Central Ltd, 2011) Mills, Edward; Bakanda, Celestin; Birungi, Josephine; Chan, Keith; Hogg, Robert; Ford, Nathan; Nachega, Jean; Cooper, CurtisBACKGROUND:Because men in Africa are less likely to access HIV/AIDS care than women, we aimed to determine if men have differing outcomes from women across a nationally representative sample of adult patients receiving combination antiretroviral therapy in Uganda. METHODS: We estimated survival distributions for adult male and female patients using Kaplan-Meier, and constructed multivariable regressions to model associations of baseline variables with mortality. We assessed person-years of life lost up to age 55 by sex. To minimize the impact of patient attrition, we assumed a weighted 30% mortality rate among those lost to follow up. RESULTS: We included data from 22,315 adults receiving antiretroviral therapy. At baseline, men tended to be older, had lower CD4 baseline values, more advanced disease, had pulmonary tuberculosis and had received less treatment follow up (all at p < 0.001). Loss to follow up differed between men and women (7.5 versus 5.9%, p < 0.001). Over the period of study, men had a significantly increased risk of death compared with female patients (adjusted hazard ratio 1.43, 95% CI 1.31-1.57, p < 0.001). The crude mortality rate for males differed importantly from females (43.9, 95% CI 40.7-47.0/1000 person-years versus 26.9, 95% CI 25.4-28.5/1000 person years, p < 0.001). The probability of survival was 91.2% among males and 94.1% among females at 12 months. Person-years of life lost was lower for females than males (689.7 versus 995.9 per 1000 person-years, respectively). CONCLUSIONS: In order to maximize the benefits of antiretroviral therapy, treatment programmes need to be gender sensitive to the specific needs of both women and men. Particular efforts are needed to enroll men earlier into care.
- ItemOpen AccessSurvival of HIV-infected adolescents on antiretroviral therapy in Uganda: findings from a nationally representative cohort in Uganda(Public Library of Science, 2011) Bakanda, Celestin; Birungi, Josephine; Mwesigwa, Robert; Nachega, Jean B; Chan, Keith; Palmer, Alexis; Ford, Nathan; Mills, Edward JBACKGROUND: Adolescents have been identified as a high-risk group for poor adherence to and defaulting from combination antiretroviral therapy (cART) care. However, data on outcomes for adolescents on cART in resource-limited settings remain scarce. METHODS: We developed an observational study of patients who started cART at The AIDS Service Organization (TASO) in Uganda between 2004 and 2009. Age was stratified into three groups: children (≤10 years), adolescents (11-19 years), and adults (≥20 years). Kaplan-Meier survival curves were generated to describe time to mortality and loss to follow-up, and Cox regression used to model associations between age and mortality and loss to follow-up. To address loss to follow up, we applied a weighted analysis that assumes 50% of lost patients had died. FINDINGS: A total of 23,367 patients were included in this analysis, including 810 (3.5%) children, 575 (2.5%) adolescents, and 21 982 (94.0%) adults. A lower percentage of children (5.4%) died during their cART treatment compared to adolescents (8.5%) and adults (10%). After adjusting for confounding, other features predicted mortality than age alone. Mortality was higher among males ( p <0.001), patients with a low initial CD4 cell count ( p <0.001), patients with advanced WHO clinical disease stage ( p <0.001), and shorter duration of time receiving cART ( p <0.001). The crude mortality rate was lower for children (22.8 per 1000 person-years; 95% CI: 16.1, 29.5), than adolescents (36.5 per 1000 person-years; 95% CI: 26.3, 46.8) and adults (37.5 per 1000 person-years; 95% CI: 35.9, 39.1). Interpretation This study is the largest assessment of adolescents receiving cART in Africa. Adolescents did not have cART mortality outcomes different from adults or children.
