A systematic review of emergency department based HIV testing and linkage to care initiatives in low resource settings.

In the United States ED-based HIV testing strategies have been front and center at curbing the HIV epidemic. The limited number of ED-based studies we observed in this study may represent the paucity of HIV testing in this venue in LMICs. All of the studies in this review demonstrated a high prevalence of HIV infection in the ED and an extraordinarily high percentage of previously undiagnosed HIV infection. Although the numbers of published reports are few, these diverse studies imply that in HIV endemic low resource settings EDs carry a large burden of undiagnosed HIV infections and may offer a unique testing venue.
