Acceptability and uptake of HIV self‐testing in emergency care settings: A systematic review and meta‐analysis. (21st July 2021) - Aluisio, Adam R.
Abstract: Background: Emergency departments (ED) interface with large numbers of patients that are often missed by conventional HIV testing approaches. ED‐based HIV self‐testing (HIVST) is an innovative engagement approach which has potential for testing gains among populations that have failed to be reached. This systematic review and meta‐analysis evaluated acceptability and uptake of HIVST, as compared to standard provider‐delivered testing approaches, among patients seeking care in ED settings. Methods: Six electronic databases were systematically searched (Dates: January 1990–May 2021). Reports with data on HIVST acceptability and/or testing uptake in ED settings were included. Two reviewers identified eligible records (κ= 0.84); quality was assessed using formalized criteria. Acceptability and testing uptake metrics were summarized, and pooled estimates were calculated using random‐effects models with assessments of heterogeneity. Results: Of 5773 records identified, seven met inclusion criteria. The cumulative sample was 1942 subjects, drawn from three randomized control trials (RCTs) and four cross‐sectional studies. Four reports assessed HIVST acceptability. Pooled acceptability of self‐testing was 92.6% (95% confidence interval [CI]: 88.0%–97.1%). Data from two RCTs demonstrated that HIVST significantly increased testing uptake as compared to standard programs (risk ratio [RR] = 4.41, 95% CI: 1.95–10.10, I 2 = 25.8%). Overall, the quality of evidence was low (42.9%) or very low (42.9%), with one report of moderate quality (14.2%). Conclusions: Available data indicate that HIVST may be acceptable and may increase testing among patients seeking emergency care, suggesting that expanding ED‐based HIVST programs could enhance HIV diagnosis. However, given the limitations of the reports, additional research is needed to better inform the evidence base.
