Schematic of a proposed feedback loop identifying target areas to improve the processes of engagement in care by patients infected with human immunodeficiency virus (HIV). Enhanced, real-time patient-level surveillance with appropriate attention to patient protections should inform educational initiatives and resource allocation for integrated testing, linkage to care plus (TLC+) service delivery. Ongoing evaluation of programmatic performance in achieving defined benchmarks for linkage of patients with newly diagnosed infection and retention of those in care are imperative to inform feedback and further educational efforts and refinement of service delivery and resource allocation. Although health information technology may facilitate implementation of the steps encompassed in this feedback loop, there is an essential human element integral to the successful performance of these activities.
