INTRODUCTION The Canadian HIV and Aging Cohort Study (CHACS) is a multi-centre, prospective, controlled cohort study including a biobank, that aims to characterize pathways and to identify predictors of accentuated aging and cardiovascular diseases (CVDs) among people living with HIV. The CHACS protocol and detailed data collection plan have been previously published [1]. Recruitment of people living with and without HIV has been ongoing in 10 Canadian clinical centres since 2011.

KEY POINTS Pre-exposure prophylaxis (PrEP) is a highly effective modality for HIV prevention that can be prescribed by generalists. Pre-exposure prophylaxis should be offered to patients who are at high risk of HIV exposure, including gay, bisexual and other men who have sex with men (GBM), women reporting condomless intercourse with partners of confirmed or unknown transmissible HIV status and persons who inject drugs and share injection equipment.

Setting Canadian university hospital. Participants Adults born after 1945 who consulted at ER for any condition and on any shift were included. Patients unable to opt-out were excluded.
