To assess the impact of comorbidities (CMs) on costs, utilities and health-related quality of life (HRQOL) among HIV patients in Colombia.
A cross-sectional study was conducted among 138 HIV patients at an outpatient clinic in Bogotá to assess their costs, utilities (EQ5D-5L) and HRQOL (EQ-VAS). CMs and other covariates were gathered from patient records. Multiple regression models were conducted to assess the impact of CMs.
Of all patients, 72% experienced CMs; of these, half experienced ≥2 CMs (N=49). CMs had a statistically significant impact on utilities when the EQ5D-5L (P=0.022) was applied among patient with ≥2 CMs. No statistical significance was found for the impact of CMs on costs.
This study suggests that having multiple CMs significantly influences utility, and CMs have some impact on HRQOL measured using the EQ-VAS but this effect is at the border of significance. No significant impact was observed on costs.
