Proportion of Patients Screened for HCV Infection, HCV Antibody Positive, and Unnecessarily Tested for HCV Infection (2006–2011).

Abbreviations: HET, heterosexual transmission; IDU, injection drug use; MSM, men who have sex with men. *Continuous variables were dichotomized to facilitate calculation of proportions. The mean value divided the number of outpatient HIV visits during the observation period into two groups; whereas the number of inpatient and emergency department visits during the observation period differentiated between 0 and 1 or more visits. †P<0.05 when comparing differences in the proportion screened for HCV using the χ2 test. ‡P<0.05 when comparing differences in the proportion HCV antibody positive using the χ2 test. §P<0.05 when comparing differences in the proportion unnecessary tested for HCV using the χ2 test.
