HIV AIDS (Auckl) 2018 10 103-114 Background: Understanding trends in patient profiles and identifying predictors for adverse outcomes are key to improving the effectiveness of HIV care and treatment programs. Previous work in Kenya has documented findings from a rural setting. This paper describes trends in demographic and clinical characteristics of antiretroviral therapy (ART) treatment cohorts at a large urban, referral HIV clinic and explores treatment outcomes and factors associated with attrition during 12 years of follow-up. Methods: This was a retrospective cohort analysis of HIV-infected adults who started ART between January 1, 2004, and September 30, 2015. ART-experienced patients and those with missing data were excluded. The Cochran-Armitage test was used to determine trends in baseline characteristics over time. Cox proportional hazards models were used to determine the effect of baseline characteristics on attrition. Results: ART uptake among older adolescents (15-19 years), youth, and young adults increased over time (p=0.0001). Independent predictors for attrition included (adjusted hazard ratio [95% CI]) male sex: 1.30 (1.16-1.45), p=0.0001; age: 15-19 years: 1.83 (1.26-2.66), p=0.0014; 20-24 years: 1.93 (1.52-2.44), p=0.0001; and 25-29 years: 1.31 (1.11-1.54), p=0.0012; marital status - single: 1.27 (1.11-1.44), p=0.0005; and divorced/separated: 1.56 (1.30-1.87), p=0.0001; urban residence: 1.40 (1.20-1.64), p=0.0001; entry into HIV care following hospitalization: 1.31 (1.10-1.57), p=0.0026, or transfer from another facility: 1.60 (1.26-2.04), p=0.0001; initiation of ART more than 12 months after the date of HIV diagnosis: 1.36 (1.19-1.55), p=0.0001, and history of a current or past opportunistic infection (OI): 1.15 (1.02-1.30), p=0.0284. Conclusion: Although ART uptake among adolescents and young people increased over time, this group was at increased risk for attrition. Single marital status, urban residence, history of hospitalization or OI, and delayed initiation of ART also predicted attrition. This calls for focused evidence-informed strategies to address attrition and improve outcomes. |
Trends in clinical characteristics and outcomes of Pre-ART care at a large HIV clinic in Nairobi, Kenya: a retrospective cohort study
Mecha JO , Kubo EN , Nganga LW , Muiruri PN , Njagi LN , Mutisya IN , Odionyi JJ , Ilovi SC , Wambui M , Githu C , Ngethe R , Obimbo EM , Ngumi ZW . AIDS Res Ther 2016 13 38 BACKGROUND: The success of antiretroviral therapy in resource-scarce settings is an illustration that complex healthcare interventions can be successfully delivered even in fragile health systems. Documenting the success factors in the scale-up of HIV care and treatment in resource constrained settings will enable health systems to prepare for changing population health needs. This study describes changing demographic and clinical characteristics of adult pre-ART cohorts, and identifies predictors of pre-ART attrition at a large urban HIV clinic in Nairobi, Kenya. METHODS: We conducted a retrospective cohort analysis of data on HIV infected adults (≥15 years) enrolling in pre-ART care between January 2004 and September 2015. Attrition (loss to program) was defined as those who died or were lost to follow-up (having no contact with the facility for at least 6 months). We used Kaplan-Meier survival analysis to determine time to event for the different modes of transition, and Cox proportional hazards models to determine predictors of pre-ART attrition. RESULTS: Over the 12 years of observation, there were increases in the proportions of young people (age 15 to 24 years); and patients presenting with early disease (by WHO clinical stage and higher median CD4 cell counts), p = 0.0001 for trend. Independent predictors of attrition included: aHR (95% CI): male gender 1.98 (1.69-2.33), p = 0.0001; age 20-24 years 1.80 (1.37-2.37), p = 0.0001), or 25-34 years 1.22 (1.01-1.47), p = 0.0364; marital status single 1.55 (1.29-1.86), p = 0.0001) or divorced 1.41(1.02-1.95), p = 0.0370; urban residency 1.83 (1.40-2.38), p = 0.0001; CD4 count of 0-100 cells/µl 1.63 (1.003-2.658), p = 0.0486 or CD4 count >500 cells/µl 2.14(1.46-3.14), p = 0.0001. CONCLUSIONS: In order to optimize the impact of HIV prevention, care and treatment in resource scarce settings, there is an urgent need to implement prevention and treatment interventions targeting young people and patients entering care with severe immunosuppression (CD4 cell counts <100 cells/µl). Additionally, care and treatment programmes should strengthen inter-facility referrals and linkages to improve care coordination and prevent leakages in the HIV care continuum. |
Enhancing maternal and child health using a combined mother & child health booklet in Kenya
Mudany MA , Sirengo M , Rutherford GW , Mwangi M , Nganga LW , Gichangi A . J Trop Pediatr 2015 61 (6) 442-7 Under Kenyan guidelines, HIV-exposed infants should be tested for HIV DNA at 6 weeks or at first clinical contact thereafter, as infants come for immunization. Following the introduction of early infant diagnoses programmes, however, many infants were not being tested and linked to care and treatment. We developed the Mother & Child Health Booklet to help relate mothers' obstetrical history to infants' healthcare providers to facilitate follow-up and timely management. The booklet contains information on the mother's pregnancy, delivery and postpartum course and her child's growth and development, immunization, nutrition and other data need to monitor the child to 5 years of age. It replaced three separate record clinical cards. In a 1 year pilot evaluation of the booklet in Nyanza province in 2007-08, the number of HIV DNA tests on infants increased by 34% from 9966 to 13 379. The booklet was subsequently distributed nationwide in 2009. Overall, the numbers of infants tested for HIV DNA rose from 27 000 in 2007 to 60 000 in 2012, which represents approximately 60% of the estimated HIV-exposed infants in Kenya. We believe that the booklet is an important strategy for identifying and treating infected infants and, thus, in progress toward Millennium Development Goal 4. |
