Trends in Mortality in People With HIV From 1999 through 2020: A Multicohort Collaboration

Background: Mortality among people with human immunodeficiency virus (HIV) declined with the introduction of combination antiretroviral therapy. We investigated trends in mortality in people with HIV from 1999 through 2020. Methods: Data were collected from the Data Collection on Adverse events of Anti-HIV Drugs (D:A:D) cohort between January 1999 through January 2015 and the International Cohort Consortium of Infectious Disease (RESPOND) from October 2017 through December 2020. Age-standardized all-cause and cause-specific mortality rates, classified using Coding Causes of Death in HIV, were calculated. Poisson models were used to assess mortality over time. Results: Among 55 716 participants followed for median 6 years (interquartile range, 3-11), 5263 died (mortality rate [MR], 13.7/1000 person-years of follow-up [PYFU]; 95% confidence interval [CI], 13.4-14.1). Changing mortality was observed: AIDS mortality was most common between 1999-2009 (n = 952; MR, 4.2/1000 PYFU; 95% CI, 4.0...
