Incarcerated populations experience higher rates of sexually transmitted infections (STIs) than the general population, alongside inconsistent testing strategies. In response, universal opt-out STIs (chlamydia, gonorrhea, syphilis, and HIV) screening was implemented at admission in a short-term correctional facility in Alberta, Canada, for individuals ≤35 years. A cross-sectional, retrospective evaluation of testing outcomes between March 2018 and February 2020 was completed. Descriptive statistics were used to stratify STIs by gender, age group, and date for univariate analysis. Despite low uptake (31.2%), opt-out screening resulted in high positivity rates (14.9%, 10.8%, 29.5%, and 0.3%, respectively) and treatment completion (93.7%) while capturing a high proportion (52.6%) of asymptomatic cases. Opt-out screening at admission is feasible and can improve STI testing in high-risk individuals experiencing incarceration in Canada.
