Expanding HIV Testing Among Uganda Adults Who Utilize Traditional Healers

Study Overview
=================
Brief Summary
-----------------
HIV antiretroviral therapy has the potential to dramatically decrease HIV transmission worldwide1; yet, a barrier to ending the AIDS epidemic in low-resource settings is the fact that healthcare is largely provided by traditional or spiritual healers rather than biomedical providers, and there are no strategies in place to identify HIV-infected patients among Traditional Healer patients and link them to HIV care. In order to reach the UNAIDS 90-90-90 benchmarks HIV services must reach marginalized populations in endemic regions, such as in southwestern Uganda. Uganda is one of seven sub-Saharan African (SSA) countries accounting for 90% of all new HIV infections in this region6. HIV prevalence is 7.3%, with  1.5 million people living with HIV/AIDS and 99,000 new infections in 2014. However, only 50% of sexually active Ugandans have ever tested for HIV8. In the project location of southwestern Uganda, like much of SSA, the majority of Ugandans utilize Traditional Healers (TH), but little is known about Traditional Healer practices or rates of HIV testing (or HIV infection) among their clients. Specific aims of this study are to: 1) identify key socio-structural factors that frame HIV testing behaviors among Ugandan adults who utilize Traditional Healers; 2) investigate acceptability of providing point-of-care HIV testing at Traditional Healer practice locations; and 3) develop and pilot a prospective HIV testing intervention among Traditional Healer patients to promote earlier diagnosis. Results will be used to implement subsequent, large-scale cluster-randomized HIV testing intervention at Traditional Healer practice locations. Findings from the proposed study include formative data on populations that utilize Traditional Healers in an HIV-endemic region of Uganda, and pilot testing of an HIV testing intervention at healer practice locations; these results could be applied towards expanding HIV testing in other low-resource, endemic settings.

Detailed Description
-----------------
This study has three specific aims: Specific Aim 1: Identify key socio-structural factors that frame HIV testing behaviors among clients of Ugandan TH, using an exploratory sequential, mixed-methods study design. First, qualitative interviews with 25-35 purposely-sampled TH clients will characterize the care-seeking trajectory, HIV testing behaviors and related stigma, healthcare costs, and HIV risks and exposures. Based on these results, a survey will be designed and administered to 300 Ugandan adults who utilize TH in Mbarara District. This cross-sectional study will identify 1) rates of HIV testing among TH clients and 2) variables that independently predict HIV testing within the prior 12 months. These data will inform a model of HIV testing behavior among TH clients based on the Andersen Model of Healthcare Utilization, and generate hypotheses to be tested in Specific Aim 2. Specific Aim 2: Characterize acceptability of receiving point-of-care (POC) HIV testing at TH locations, using an exploratory sequential, mixed-methods approach. Qualitative interviews with 15-25 purposely sampled TH and 15-25 purposely-sampled TH clients will explore attitudes and experiences with biomedicine, feasibility and acceptability of delivering POC HIV testing at TH locations, and investigate relevant themes emerging from Aim 1. Based on qualitative results, a survey will be developed and administered to 175 TH in Mbarara District. This cross-sectional study will characterize TH practices relevant to HIV testing, and identify characteristics of healers who favorably view the proposed intervention (Specific Aim 3). These data will be integrated with results from SA1 to develop an intervention that will overcome socio-structural barriers to HIV testing. Specific Aim 3: Develop and pilot an HIV testing intervention among TH clients using a cluster randomized study design. Integration of results from SA1 and SA2 will inform a pilot HIV testing intervention at 9 TH practice locations, to be compared with a control group receiving usual TH care at 8 practices. This pilot will offer HIV testing at TH practice sites to 250 TH clients at the intervention arm sites, and offer protocoled usual care to 250 clients at control arm sites. Primary outcome for this study will be rates of HIV testing among TH clients. Secondary outcomes will include i) number of new HIV diagnoses among TH clients, and ii) number of patients with +HIV POC test who successfully link to HIV care in 3 months.

Design Details

Primary Purpose: Health Services Research
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: This is a mixed methods study where Aims 1 and 2 have both qualitative and quantitative arms. Aim 3 is an unblinded intervention, with a control arm, to be delivered in cluster-randomized fashion (Sept 2019-June 2020). Healers will be treated as clusters and randomized to either intervention or control arm.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Healer HIV testing intervention<br>We will follow Ugandan National protocols to administer voluntary HIV testing at 9 TH practice locations throughout Mbarara District over a 9 month period. | Behavioral: HIV testing at traditional healer practices<br>* HIV 1/2 antigen-antibody POC test (Oraquick©) will be administered to those participants who agree to test. Pre-test counseling will be performed before results are delivered. Clients with positive tests will be provided with detailed contact information for the MUST ISS clinic, and given specific instructions to present to the clinic as soon as possible for confirmatory testing and linkage to care.<br>|
| No Intervention: Healer control arm<br>Patients will undergo protcolized usual TH care at 8 practices, which include HIV education and a referral to receive VCT through existing resources. Study staff will contact the client at 3 months following enrollment to assess for self-report of VCT. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of TH Clients Who Received HIV Testing | Primary study outcome was receipt of an HIV test within 90 days of enrollment. In the control arm, this was assessed via self-report at time of 90-day phone call follow up. For intervention arm, the participating healer recorded whether an HIV test was accepted by the participant at the time of the study visit. If the HIV test was accepted and delivered, the healer recorded the result of the test. | within 3 months following study visit | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of New HIV Diagnoses Among TH Clients | For intervention arm participants, the healer recorded the result of the point-of-care HIV test for those participants who agreed to test during the study visit. In the control arm, this outcomes was assessed via self-report during the 90-day follow up phone call. | within three months following enrollment. | 
| Number of Patients With +HIV Test Who Successfully Link to HIV Care | This outcome was assessed via self-report during the 90-day follow up phone call. For participants newly testing HIV-positive, questions were posed to determine if they had received confirmatory testing, and initiated ART medication. | at three months following enrollment. | 
| Age in Years of Control Arm Subjects Who Received an HIV Test | Participants in the control arm assessed for primary outcomes of receiving an HIV test within 3 months of study enrollment. Participant age in years at time of study enrollment, and association with primary outcome of receiving an HIV test | 3 months following study enrollment | 
| Gender of Control Arm Subjects Who Received an HIV Test | Self-reported participant gender and association with primary study outcome of receiving an HIV test | at 3 months following enrollment | 
| Highest Level of Education for Control Arm Subjects Who Received an HIV Test | Participant self-reported highest level of education, and association with study primary outcome of receiving an HIV test | at 3 months following study enrollment |
