Sensitivity analysis on proportion of risk groups in human immunodeficiency virus (HIV) testing in hospital, outpatient clinic, and emergency department (ED) settings. The baseline distribution of HIV testing in each setting was as follows: hospital-based: 92.7% heterosexual, 3.3% men who have sex with men (MSM), 4.0% people who inject drugs (PWID); outpatient clinic: 96.6% heterosexual, 2.1% MSM, 1.3% PWID; ED: 94.7% heterosexual, 3.2% MSM, 2.0% PWID. The proportions of heterosexuals tested in each scenario were adjusted accordingly. All results were for the combined intervention, sustained over the complete study time horizon. Abbreviations: HIV, human immunodeficiency virus; ICER, incremental cost-effectiveness ratio; MSM, men who have sex with men; PWID, people who inject drugs; QALY, quality-adjusted life-years.
