Improving HIV Testing Among Children Under Five in Rural Uganda

Five traditional healers (TH) will be trained in the intervention to facilitate HIV counseling and testing for children under five. The other five will provide "enhanced standard of care", where healers will participate in a pre-trial educational session describing community HIV resources available for clients, and how to access them. The investigators will enroll 400 children at these 10 TH practices over a nine-month period, 200 in the intervention arm and 200 in the control. Exit interviews with all participating TH and a sample of participant caretakers will assess concepts pertinent to intervention sustainment.

RAs will arrive at the TH location within one hour to complete enrollment and written informed consent for those who endorse interest in the study after it is introduced by the TH. Once informed consent has been completed, the TH will offer counseling and rapid HIV testing or referral to the nearest health facility depending on the arm. The investigators will recruit all eligible children regardless of whether their caretaker consents for them to receive an HIV test. After enrollment, participants will receive a de-identified study identification number and caregivers will complete a locator information form with contact information (mobile phone, residency, and employment information) and information for additional contact persons. Contact persons will be peers or family members the study team can contact in case the primary caretaker is not reachable for follow-up through other means. This strategy has been feasible and effective to conduct follow up in research among adults living with HIV.

Study Training: Five participating TH for the control arm will receive a two-day training session on pediatric HIV, risk factors, and how to refer patients for testing. Five participating TH will attend a two-day training session in facilitating pediatric-specific HIV counseling and rapid oral swab testing. Both trainings will be conducted by clinicians from the ISS clinic (physicians, nurses, counselors, and social workers). Training will follow the approach in our previously effective trial, tailored to the pediatric population. A final training curriculum will be developed in Aim 1. TH will receive instruction on delivering family-centered pre-and post-HIV test counseling with observed practice sessions and hands-on use of Oraquick® oral swab test kits. These tests are endorsed by the Ugandan MoH and WHO for community layperson HIV self-testing in non-clinical settings. The test is rated as 99.3% sensitive and 99.8% specific. Verbal assessments of knowledge with teach back will occur one-on-one in a private setting. Incorrect answers will be re-explained, then assessments re-administered. Counselling and testing will be directly observed by Dr. Nansera and ISS clinicians to ensure HCT is delivered as instructed.

Study Procedures: A trained, study RA will collect demographics from the child's caretaker on enrollment including age, sex, birth history, prior HIV testing, household characteristics (income, distance to TH, mode of transportation), and biological parent data including age, marital status, and HIV history (including prior testing). RAs will administer validated scales at enrollment to measure caretaker characteristics including social support, self-efficacy, HIV-related stigma, and HIV knowledge. All scales have been validated in similar East African populations. Following informed consent by caregivers, TH will offer pre-test counseling and - if accepted - facilitate HIV testing or refer to a nearby facility depending on the arm. Method of oral swab collection will depend on caretaker and child preference: TH can perform the oral mucosal swab, or supervise caretakers in performing the swab. Counseling and testing will take place in a private location. Results are available in 15 minutes and will be delivered verbally to the caretaker and in written format. Infants less than 18 months old are not eligible to receive rapid HIV testing per MoH guidelines. Caretakers of infants will be given a referral form and instructed to go to a local clinic for HIV testing if the child has not received an HIV test in the past three months And is potentially exposed, similar to those in the control arm.

Caretakers of children with reactive tests at the TH will receive pediatric-specific post-test counseling on their child's potential diagnosis and a referral form with location and contact information for the ISS Maternal and Pediatric clinic and other nearby HIV clinics, with instructions to present to the nearest clinic for confirmatory testing as soon as possible. TH will also offer oral swab testing to biologic parents of HIV-reactive children. Caretakers of participants with non-reactive tests will receive counseling on HIV prevention strategies including primary HIV prevention for the mother and need for repeat HIV testing every three months while breastfeeding. Those at the control sites will undergo testing at the local health facility and post-test counseling per the Ugandan MOH protocol. Study staff will conduct drop-ins throughout the study and contact TH weekly to observe and answer questions about counseling, test kit use, or eligibility screening to ensure integrity and minimize social harm. Testing kits will be provided by the study for all participating TH and provided to clients at no charge. Intervention delivery will be monitored by the Project Manager using the fidelity and feedback plan developed in Aim 1.
