Introduction
As people with HIV (PWH) age, they experience prolonged exposure to HIV and antiretroviral therapy, increased risks of developing age‐related HIV‐associated non‐AIDS (HANA) comorbidities and higher rates of hospitalization. Few studies have explored the ageing of PWH and its impact on hospital stays in the US. This study examined trends, characteristics and comorbidities associated with hospital stays with HIV (HSWH) as compared with hospital stays without HIV (HSWOH).
Methods
Thirteen years of pooled National Inpatient Sample (NIS) data from 2003 through 2015 were analysed to describe yearly trends. Trends were evaluated for eight major HANA conditions (cardiovascular disease, cancer, diabetes, liver disease, bone loss, kidney disease, pulmonary disease and neurological disease) across four age groups (18–34, 35–49, 50–64, 65+ years).
Results
Although overall rates of hospitalization reduced across all age groups, the proportion of HIV‐related hospitalization increased among older Americans. The average number of chronic conditions was higher for HSWH among all age groups and disproportionately increased for older PWH. Although age‐adjusted rates of cardiovascular disease, cancer, bone loss and pulmonary disease were lower for HSWH relative to HSWOH, rates increased disproportionately over the study period. The prevalence of all major HANA conditions except cancer and diabetes increased among the elderly (65+), and the prevalence of cardiovascular disease, cancer, bone loss, kidney disease and pulmonary disease also increased among patients aged 50–64 years.
Conclusions
Higher rates of hospitalizations and HANA comorbidities were observed among older HIV patients. The ageing of PWH suggests increased future hospital resource utilization for HSWH. Appropriate training of healthcare providers is essential to managing increased comorbidity burdens of older PWH during hospital stays in the US.
