For this, lay HCWs require adequate specialized training. Digital technologies hold promise for training lay HCWs in low-resource settings, but their impacts on improving knowledge, attitudes, and skills are not understood.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study evaluates the impact of digital training on lay HCWs\u2019 knowledge, attitudes, and skills to provide HIV index case testing.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We recruited lay HCWs from 34 health facilities in Malawi. We conducted a 2-arm cluster randomized controlled trial from 2022 to 2023, evaluating the impact of a digital training approach. Health facilities (clusters) were randomized 1:2 to the enhanced or standard arms. Lay HCWs in both arms received the standard in-person index case testing training. In addition, lay HCWs in the enhanced arm received tablet-guided training. Knowledge acquisition was measured using multiple-choice questionnaires administered before and after training. Attitudinal gains were assessed through a questionnaire with Likert scale responses before and after training. Between-arm mean differences were evaluated using generalized estimating equations. Skills (fidelity to index and contact testing protocols) were measured using 15-item checklists. Fidelity scores were compared between the enhanced and standard arms by estimating mean differences and 95% CIs using generalized estimating equations.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n We enrolled 306 lay HCWs, with 125 (40.8%) in the enhanced arm and 181 (59.2%) in the standard arm. In the enhanced arm, there was 100% completion of the digital portion, 98% (123\/125) completion of the face-to-face tablet-guided portion, and 81% (101\/125) to 93% (116\/125) completion of quality improvement sessions. Knowledge improved by 4.4% (95% CI 0.7%-8.2%) more in the enhanced arm than in the standard arm (\n P<\/jats:italic>\n =.02). Attitudes toward digital training improved by 4.5% (95% CI 0.3%-7.0%) more in the enhanced arm than in the standard arm (\n P<\/jats:italic>\n =.03). Lay HCWs\u2019 fidelity to index client counseling protocols was 30.5 (95% CI 26.0%-35.0%;\n P<\/jats:italic>\n <.001) percentage points higher in the enhanced arm than in the standard arm. Fidelity to contact client counseling protocols was 24.0 (95% CI 20.6%-27.3%;\n P<\/jats:italic>\n <.001) percentage points higher in the enhanced arm than in the standard arm.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Digital training improved lay HCWs\u2019 knowledge, attitudes, and skills surrounding index case testing counseling. These findings support digital training as a useful strategy for strengthening the capacity of lay HCWs in low-resource contexts.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/89942","type":"journal-article","created":{"date-parts":[[2026,5,30]],"date-time":"2026-05-30T18:15:06Z","timestamp":1780164906000},"page":"e89942-e89942","source":"Crossref","is-referenced-by-count":0,"title":["Digital Training for Lay Health Care Workers\u2019 Knowledge and Skills in HIV Index Case Testing: Cluster Randomized Trial"],"prefix":"10.2196","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5649-0817","authenticated-orcid":false,"given":"Tapiwa A","family":"Tembo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9759-9966","authenticated-orcid":false,"given":"Nora E","family":"Rosenberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8592-5154","authenticated-orcid":false,"given":"Katie","family":"Mollan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6190-7798","authenticated-orcid":false,"given":"Maria","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1571-6576","authenticated-orcid":false,"given":"Sarah E","family":"Rutstein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-9965-9859","authenticated-orcid":false,"given":"Angella M","family":"Mkandawire","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2835-4605","authenticated-orcid":false,"given":"Mike J","family":"Chitani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5707-0489","authenticated-orcid":false,"given":"Caroline","family":"Kumbuyo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3605-9949","authenticated-orcid":false,"given":"Duncan","family":"Phiri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-7734-3780","authenticated-orcid":false,"given":"Mtisunge","family":"Mphande","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4126-5844","authenticated-orcid":false,"given":"Elijah","family":"Kavuta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6930-1154","authenticated-orcid":false,"given":"Samuel","family":"Chilala","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0021-4298","authenticated-orcid":false,"given":"Jiayu","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2493-5025","authenticated-orcid":false,"given":"Saeed","family":"Ahmed","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9232-2653","authenticated-orcid":false,"given":"Katherine","family":"Simon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0755-4386","authenticated-orcid":false,"given":"Linda-Gail","family":"Bekker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,7,15]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","unstructured":"WHO guideline on health policy and system support to optimize community health worker programmes.
