Proportion of Harris Health (HH) outpatient clinic patients who received an HIV test in a given year (annual testing) or at any time since 2002 (ever tested). Data fitted with linear regression models containing splines. The included splines reflect the only significant jumps in the annual HIV testing rate and ever HIV tested rate, which were observed in 2009, coinciding with the implementation of the RUSH program in the emergency centers. m=slope; CDC=Centers for Disease Control and Prevention; HIV=Human Immunodeficiency Virus; RUSH=Routine Universal Screening for HIV; EC=Emergency Center; USPSTF=U.S. Preventive Services Task Force
