HIV Self-Testing Acceptability among Injured Persons Seeking Emergency Care in Nairobi, Kenya

Abstract Emergency Department-based HIV self-testing (ED-HIVST) could increase HIV testing services to under-reached key groups. Injury patients presenting to the Kenyatta National Hospital Accident and Emergency Department were enrolled from March-May 2021. Likert item data on HIVST assessing domains of general acceptability, personal acceptability, and acceptability to distribute to social and/or sexual networks were collected. Ordinal regression was performed yielding adjusted odds ratios (aOR) to identify characteristics associated with high HIVST acceptability across domains. Of 600 participants, 88.7% were male, and the median age was 29. Half reported having primary care providers (PCPs) and 86.2% reported prior HIV testing. For each Likert item, an average of 63.5% of participants reported they “Agree Completely” with positive statements about ED-HIVST in general, for themselves, and for others. In adjusted analysis for general acceptability, those < 25 (aOR = 1.67, 95%CI:1.36–2.08) and with prior HIV testing (aOR = 1.68, 95%CI:1.27–2.21) had greater odds of agreeing completely. For personal acceptability, those with a PCP (aOR = 3.31, 95%CI:2.72–4.03) and prior HIV testing (aOR = 1.83, 95%CI:1.41–2.38) had greater odds of agreeing completely. For distribution acceptability, participants with a PCP (aOR = 2.42, 95%CI:2.01–2.92) and prior HIV testing (aOR = 1.79, 95%CI: 1.38–2.33) had greater odds of agreeing completely. ED-HIVST is perceived as highly acceptable, and young people with prior testing and PCPs had significantly greater favorability. These data provide a foundation for ED-HIVST program development in Kenya.
