We sought to evaluate uptake and patterns of use of PEP among men and women in rural Uganda and Kenya.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We analysed PEP uptake from three randomized trials enrolling persons aged \u226515 years with HIV risk from antenatal clinics, outpatient departments and community settings from April through August 2021 (NCT04810650). In each trial, participants were randomized to a person\u2010centred, dynamic choice HIV prevention (DCP) model or standard\u2010of\u2010care (SoC) arm. DCP offered choice of biomedical product (oral pre\u2010exposure prophylaxis [PrEP] or PEP) with an option to switch over time; service location (clinic vs. out\u2010of\u2010clinic); testing option (rapid blood\u2010based test or oral HIV self\u2010test). The SoC offered HIV prevention services as per in\u2010country guidelines. In both arms, PEP comprised a 28\u2010day oral Tenofovir\/Lamivudine\/Dolutegravir course with HIV testing at start and end of the 28\u2010day period. We described patterns of and predictors of self\u2010reported PEP use over the 12 months of follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1232 participants were enrolled, balanced by arm and country. Of the 1147 (93%) who completed at least one survey on self\u2010reported use of biomedical prevention, the median follow\u2010up time was 12 months [IQR: 11, 12]. Overall, a total of 104 courses of PEP were dispensed to 59 participants. PEP use was significantly higher among persons enrolled in the DCP arm (relative risk [RR]\u00a0=\u00a03.30; 95% CI: 1.58\u22126.91), from Uganda (RR\u00a0=\u00a03.17; 95% CI: 1.53\u22126.59), reporting alcohol use (RR\u00a0=\u00a02.20; 95% CI: 1.30\u22123.72) and men (RR\u00a0=\u00a02.08; 95% CI: 1.11\u22123.91). Of the 59 PEP users, 14 (24%) transitioned to PrEP and 28(47%) used PEP on more than one occasion. Multiple uses of PEP were more common among persons from Uganda versus Kenya (RR\u00a0=\u00a04.43; 95% CI: 1.10\u221217.80) and persons enrolled from the community (RR\u00a0=\u00a04.45; 95% CI: 1.89\u221210.45) versus clinic. There were no seroconversions reported among PEP users. No serious adverse events were reported.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>PEP reaches groups such as men and those who use alcohol who are more likely to benefit from this short\u2010term prevention modality than PrEP. There is a need to make PEP accessible within a context of person\u2010centred delivery to optimize its benefits.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jia2.26450","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T13:04:34Z","timestamp":1750943074000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Uptake and patterns of PEP use within the context of a dynamic choice HIV prevention model in rural Uganda and Kenya: SEARCH Study"],"prefix":"10.1002","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0324-4006","authenticated-orcid":false,"given":"James","family":"Ayieko","sequence":"first","affiliation":[{"name":"Center for Microbiology Research Kenya Medical Research Institute  Nairobi Kenya"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura B.","family":"Balzer","sequence":"additional","affiliation":[{"name":"Department of Biostatistics University of California  Berkeley California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colette","family":"Aoko","sequence":"additional","affiliation":[{"name":"Center for Microbiology Research Kenya Medical Research Institute  Nairobi Kenya"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helen","family":"Sunday","sequence":"additional","affiliation":[{"name":"Infectious Diseases Research Collaboration  Kampala Uganda"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9532-5710","authenticated-orcid":false,"given":"Elijah","family":"Kakande","sequence":"additional","affiliation":[{"name":"Infectious Diseases Research Collaboration  Kampala Uganda"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jane","family":"Kabami","sequence":"additional","affiliation":[{"name":"Infectious Diseases Research Collaboration  Kampala Uganda"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catherine","family":"Koss","sequence":"additional","affiliation":[{"name":"Department of Medicine University of California  San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5860-8081","authenticated-orcid":false,"given":"Gabriel","family":"Chamie","sequence":"additional","affiliation":[{"name":"Department of Medicine University of California  San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moses R.","family":"Kamya","sequence":"additional","affiliation":[{"name":"Department of Medicine Makerere University  Kampala Uganda"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maya L.","family":"Petersen","sequence":"additional","affiliation":[{"name":"Department of Biostatistics University of California  Berkeley California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0761-3136","authenticated-orcid":false,"given":"Diane V.","family":"Havlir","sequence":"additional","affiliation":[{"name":"Department of Medicine University of California  San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,6,26]]},"reference":[{"key":"e_1_2_12_2_1","unstructured":"Joint United Nations Programme on HIV\/AIDS.Understanding Fast\u2010Track: accelerating action to end the AIDS epidemic by 2030. 2015.
