In Uganda however, little is documented on treatment outcomes and their associated factors among individuals on second line ART regimen. The rapid scale-up of ART over the past has resulted in substantial reductions in morbidity and mortality. However, as millions of people must be maintained on ART for life, individuals with ART treatment failure are increasingly encountered and the numbers are expected to rise. This could be attributed to factors such as sub-standard regimens, limited access to routine viral load monitoring, treatment interruptions, suboptimal adherence, among others. The purpose of this study was to estimate 5-year cumulative treatment failure and the associated factors among individuals on second line ART regimen Eastern Uganda. Materials and methods: A retrospective analysis of 541 records of HIV positive individuals, switched to second line ART regimen from January 2012 to December 2017. Inferential statistics including the Chi square test and multivariable logistic regression analysis was applied to determine associations of treatment failure against of the selected demographic, laboratory and clinical factors was performed. Associations between treatment failure and the predictors was based on a P -value of less than 5% and confidence intervals level of 95%. Results: We reviewed 541 records of individuals on second line ART regimen, of which 350 (64.7%) were female, 226 (41.8%) were married, and 197 (36.4%) were older than 35 years. The mean age at ART initiation was 30 years (SD = 14.8), while the mean weight at ART initiation was 47 kg (SD = 18.6), (range 4-97 kg). The overall proportion of treatment failure was 23%. The cumulative mortality risk for 5 years was 12.4% and the mortality rate was 2.5 deaths per 100 individuals per year. The odds of developing treatment failure among individuals switched to ATV/r-based regimen were 44% lower as compared to individuals who were switched to LPV/r (ORadj0.56, 95% CI 0.35-0.90, P =.016). while the odds of experiencing treatment failure among individuals that used AZT at ART initiation were 43% lower as compared to individuals that used a TDF based regimen at ART initiation (ORadj0.57, 95% CI 0.33-0.98, P =.041). Conclusion: The 5 year cumulative incidence of treatment failure in a cohort of 541 individuals was 23%. The type of protease inhibitor (PI) used in second line regimen and use of AZT at ART initiation were significantly associated with treatment failure. Our study also shows that the cumulative mortality risk while on second line ART regimen was 12.4% while the mortality rate was 2.5 deaths per 100 individuals per year. Given the high level of treatment failure among individuals on second line ART regimen, yet the current ART protocols limits the use of third line ART regimens to only regional referral hospitals, the Ministry of Health should strengthen the surveillance systems for identifying individuals failing on second line ART regimen even at district hospitals and lower health facilities to facilitate timely switch to optimal regimen. The Ministry of health through the Quality Improvement Division should conduct routine onsite support supervision to sites offering ART to ensure that treatment guides and other standard of care like timely switch to appropriate regimens among others are being adhered to. Knowledge gaps identified can also be addressed through onsite Continuous Medical Educations. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
