RAMIREZ-GARCIA, Nathaly et al. Survival in people living with HIV in the framework the Colombian health system: 2011-2018. Infect. [online]. 2021, vol.25, n.4, pp.276-283.  Epub July 19, 2021. ISSN 0123-9392.


to describe the seven-year survival and predictors of mortality among people with HIV who were treated in the Colombian health system between 2011 and 2018.


64 039 people diagnosed with HIV in Colombia were included. Kaplan-Meier analysis estimated the probability of survival from the date of diagnosis. A Royston Parmar flexible parametric survival model was fitted.


The overall survival at 7 years was 94.8% (95% CI: 94.5-95.2). Survival was related to sex (men, HR: 1.2; 95% CI: 1.1-1.4; p: 0.010); people ≥50 years of age (HR: 3.1; 95% CI: 1.6-6.3; p: 0.002); subsidized regime (HR: 2.2; 95% CI: 1.9-2.5; p: <0.001); AIDS stage (HR: 2.8; 95% CI: 2.1-3.7; p: <0.001); a detectable viral load (HR: 7.1; 95% CI: 6.0-8.3; p: <0.001); and a CD4+ Lymphocyte count <350 cells/μL (HR: 1.9; 95% CI: 1.4-2.4; p: <0.001).


The probability of survival of people living with HIV increases when they are diagnosed at a young age, in those with a CD4+ T Lymphocyte count ≥350 cells/μL, an undetectable viral load (<50 copies/mL) and are not in the AIDS stage.
