Historical trends and estimated British Columbia Ministry of Health Seek and Treat for Optimal Prevention of HIV/AIDS intervention effects for human immunodeficiency virus (HIV) test initiatives. Historical aggregate-level HIV testing rates (left-hand sides of panels A–C) were extrapolated to generate counterfactual HIV testing rates, approximating the status quo (ie, no additional public health investments to scale-up testing) for the intervention period (dashed lines). Information on actual testing rates in Vancouver Coastal Health Authority, adjusted using external data, were used to estimate testing rates for each setting and by HIV risk group during the intervention period. Abbreviations: ED, emergency department; HIV, human immunodeficiency virus; MSM, men who have sex with men; PWID, people who inject drugs.
