Summary • Expanded spectrum of HIV adherence • Engagement in care includes distinct steps: Linkage, Retention and Re-engagement • Engagement in care vital for HIV treatment success at individual & population level • Early missed visits may identify patients at risk for poor long-term health outcomes • Engagement worse in groups bearing a disproportionate burden of US HIV epidemic
What Can We Do? • Incorporate adherence to care counseling into patient encounters as a matter of routine • Evaluate “no show” phenomenon at the clinic level & revise new patient orientation • Develop partnerships with local HIV testing, clinical & supportive service providers • Integrate HIV testing and linkage activities • Coordinate activities around retention and re-engagement for shared patients
