The syndemic effect of HIV/HCV co-infection and mental health disorders on acute care hospitalization rate among people living with HIV/AIDS: a population-based retrospective cohort study.
Ontology highlight
ABSTRACT: OBJECTIVE:Our primary objective was to examine the syndemic effect of HIV/HCV co-infection and mental health disorders (MHD) on the acute care hospitalization rate among people living with HIV (PLW-HIV) in British Columbia, Canada. Secondarily, we aimed to characterize the longitudinal trends in the aforementioned rate, while controlling for the effect of several factors. METHODS:In this retrospective cohort study, individuals were antiretroviral therapy-naïve, ??18 years old, initiated treatment between 1 January 2000 and 31 December 2014, and were followed for at least 6 months until 31 December 2015 or last contact. The outcome was acute care hospitalization rate (every 6-month interval) per individual. The exposure was the interaction between HIV/HCV co-infection and MHD. Generalized non-linear mixed-effects models were built. RESULTS:Of the 4046 individuals in the final analytical sample, 1597 (39%) were PLW-HIV without MHD, 606 (15%) were people living with HIV and HCV (PLW-HIV/HCV) without MHD, 988 (24%) were PLW-HIV with MHD, and 855 (21%) were PLW-HIV/HCV with MHD. The adjusted rate ratios for acute care hospitalizations were 1.31 (95% [confidence interval] 1.13-1.52), 2.01 (95% CI 1.71-2.36), and 2.53 (95% CI 2.20-2.92) for PLW-HIV with MHD, PLW-HIV/HCV without MHD, and PLW-HIV/HCV with MHD, respectively, relative to PLW-HIV without MHD. CONCLUSION:The HIV/HCV co-infection and MHD interaction demonstrated a significant effect on the rate of acute care hospitalization, particularly for PLW-HIV/HCV with MHD. Implementing widely accessible integrative care model best practices may address this public health challenge.
