Background Undiagnosed HIV infection remains substantial in key population subgroups including adolescents, older adults, and men, driving ongoing transmission in sub-Saharan Africa. We evaluated the impact, safety, and costs of community-led delivery of HIV self-testing (HIVST), aiming to increase HIV testing in underserved subgroups and stimulate demand for antiretroviral therapy (ART). Methods and findings This cluster-randomised trial, conducted between October 2018 and July 2019, used restricted randomisation (1:1) to allocate 30 group village head clusters in Mangochi district, Malawi to the community-led HIVST intervention in addition to the standard of care (SOC) or the SOC alone. The intervention involved mobilising community health groups to lead the design and implementation of 7-day HIVST campaigns, with cluster residents (≥15 years) eligible for HIVST. The primary outcome compared lifetime HIV testing among adolescents (15 to 19 years) between arms. Secondary outcomes compared: recent HIV testing (in the last 3 months) among older adults (≥40 years) and men; cumulative 6-month incidence of ART initiation per 100,000 population; knowledge of the preventive benefits of HIV treatment; and HIV testing stigma. Outcomes were measured through a post-intervention survey and at neighboring health facilities. Analysis used intention-to-treat for cluster-level outcomes. Community health groups delivered 24,316 oral fluid-based HIVST kits. The survey included 90.2% (3,960/4,388) of listed participants in the 15 community-led HIVST clusters and 89.2% (3,920/4,394) of listed participants in the 15 SOC clusters. Overall, the proportion of men was 39.0% (3,072/7,880). Most participants obtained primary-level education or below, were married, and reported a sexual partner. Lifetime HIV testing among adolescents was higher in the community-led HIVST arm (84.6%, 770/910) than the SOC arm (67.1%, 582/867; adjusted risk difference [RD] 15.2%, 95% CI 7.5% to 22.9%; p < 0.001), especially among 15 to 17 year olds and boys. Recent testing among older adults was also higher in the community-led HIVST arm (74.5%, 869/1,166) than the SOC arm (31.5%, 350/1,111; adjusted RD 42.1%, 95% CI 34.9% to 49.4%; p < 0.001). Similarly, the proportions of recently tested men were 74.6% (1,177/1,577) and 33.9% (507/1,495) in the community-led HIVST and SOC arms, respectively (adjusted RD 40.2%, 95% CI 32.9% to 47.4%; p < 0.001). Knowledge of HIV treatment benefits and HIV testing stigma showed no differences between arms. Cumulative incidence of ART initiation was respectively 305.3 and 226.1 per 100,000 population in the community-led HIVST and SOC arms (RD 72.3, 95% CI −36.2 to 180.8; p = 0.18). In post hoc analysis, ART initiations in the 3-month post-intervention period were higher in the community-led HIVST arm than the SOC arm (RD 97.7, 95% CI 33.4 to 162.1; p = 0.004). HIVST uptake was 74.7% (2,956/3,960), with few adverse events (0.6%, 18/2,955) and at US$5.70 per HIVST kit distributed. The main limitations include the use of self-reported HIV testing outcomes and lack of baseline measurement for the primary outcome. Conclusions In this study, we found that community-led HIVST was effective, safe, and affordable, with population impact and coverage rapidly realised at low cost. This approach could enable community HIV testing in high HIV prevalence settings and demonstrates potential for economies of scale and scope. Trial registration Clinicaltrials.gov NCT03541382.

IntroductionThis study will evaluate the acceptability and effectiveness of a new intervention programme called teach-test-link-trace (TTLT) model in Tigrai, Ethiopia, where peer educators counsel about HIV (teach), perform house-to-house HIV testing (test) through pinprick HIV testing (H2H) or OraQuick HIV self-testing (HIVST), link HIV-positive patients to HIV care (link) and trace lost patients house-to-house (trace).Methods and analysisThe four-arm cluster randomised trial will be conducted in five phases: Phase 1 will assess the acceptability of the TTLT model using a cross-sectional survey among adults aged 18 years irrespective of HIV status in 6909 households from 40 villages (kebeles). Phase 2 will assess effectiveness of the TTLT model through comparing intervention and control groups among HIV negative or unknown HIV status. The intervention groups will receive one of the three home-based interventions provided by peer educators: (1) demonstrate and distribute OraQuick HIV self-testing kits (HIVST), (2) perform pinprick HIV testing (H2H) and (3) offer a choice to either receive HIVST or H2H. The control group will receive the standard care in which nurses counsel and refer eligible household members to nearby health facilities to access existing HIV testing services. The primary outcomes of the interventions are proportion of individuals who know of their HIV status (first 90), link to HIV care and treatment (second 90) and meet virological suppression (third 90). We will perform process evaluation through qualitative interviews in phase 3, economic evaluation for cost-effectiveness analysis in phase 4 and a sustainability exit strategy using nominal group technique in phase 5. We will apply descriptive and inferential statistics for quantitative studies, and thematic framework analysis for qualitative studies.Ethics and disseminationEthics approval was obtained from the Southern Adelaide Clinical Health Research Ethics Committee (SAC HREC), South Australia, and findings will be disseminated through publications, conference presentations, media release and policy briefs.Trial registration numberACTRN12620000570987p.

IntroductionReaching high coverage of HIV testing remains essential for HIV diagnosis, treatment and prevention. We evaluated the effectiveness and safety of door-to-door distribution of HIV self-testing (HIVST) kits in rural Malawi.MethodsThis cluster randomised trial, conducted between September 2016 and January 2018, used restricted 1:1 randomisation to allocate 22 health facilities and their defined areas to door-to-door HIVST alongside the standard of care (SOC) or the SOC alone. The study population included residents (≥16 years). HIVST kits were provided door-to-door by community-based distribution agents (CBDAs) for at least 12 months. The primary outcome was recent HIV testing (in the last 12 months) measured through an endline survey. Secondary outcomes were lifetime HIV testing and cumulative 16-month antiretroviral therapy (ART) initiations, which were captured at health facilities. Social harms were reported through community reporting systems. Analysis compared cluster-level outcomes by arm.ResultsOverall, 203 CBDAs distributed 273 729 HIVST kits. The endline survey included 2582 participants in 11 HIVST clusters and 2908 participants in 11 SOC clusters. Recent testing was higher in the HIVST arm (68.5%, 1768/2582) than the SOC arm (48.9%, 1422/2908), with adjusted risk difference (RD) of 16.1% (95% CI 6.5% to 25.7%). Lifetime testing was also higher in the HIVST arm (86.9%, 2243/2582) compared with the SOC arm (78.5%, 2283/2908; adjusted RD 6.3%, 95% CI 2.3% to 10.3%). Differences were most pronounced for adolescents aged 16–19 years (adjusted RD 18.6%, 95% CI 7.3% to 29.9%) and men (adjusted RD 10.2%, 95% CI 3.1% to 17.2%). Cumulative incidence of ART initiation was 1187.2 and 909.0 per 100 000 population in the HIVST and SOC arms, respectively (adjusted RD 309.1, 95% CI −95.5 to 713.7). Self-reported HIVST use was 42.5% (1097/2582), with minimal social harms reported.ConclusionDoor-to-door HIVST increased recent and lifetime testing at population level and showed high safety, underscoring potential for HIVST to contribute to HIV elimination goals in priority settings.Trial registration numberNCT02718274.

Abstract Background Prevention of new HIV infections is a critical public health issue. The highest HIV testing gaps are in men, adolescents 15–19 years old, and adults 40 years and older. Community-based HIV testing services (HTS) can contribute to increased testing coverage and early HIV diagnosis, with HIV self-testing (HIVST) strategies showing promise. Community-based strategies, however, are resource intensive, costly and not widely implemented. A community-led approach to health interventions involves supporting communities to plan and implement solutions to improve their health. This trial aims to determine if community-led delivery of HIVST can improve HIV testing uptake, ART initiation, and broader social outcomes in rural Malawi. Methods The trial uses a parallel arm, cluster-randomised design with group village heads (GVH) and their defined catchment areas randomised (1:1) to community-led HIVST or continue with the standard of the care (SOC). As part of the intervention, informal community health cadres are supported to plan and implement a seven-day HIVST campaign linked to HIV treatment and prevention. Approximately 12 months after the initial campaign, intervention GVHs are randomised to lead a repeat HIVST campaign. The primary outcome includes the proportion of adolescents 15–19 years old who have tested for HIV in their lifetime. Secondary outcomes include recent testing in adults 40 years and older and men; ART initiation; knowledge of HIV prevention; and HIV testing stigma. Outcomes will be measured through cross-sectional surveys and clinic registers. Economic evaluation will determine the cost per person tested, cost per person diagnosed, and incremental cost effectiveness ratio. Discussion To the best of our knowledge, this is the first trial to assess the effectiveness of community-led HTS, which has only recently been enabled by the introduction of HIVST. Community-led delivery of HIVST is a promising new strategy for providing periodic HIV testing to support HIV prevention in rural communities. Further, introduction of HIVST through a community-led framework seems particularly apt, with control over healthcare concurrently devolved to individuals and communities.

BackgroundIn Pakistan chronic obstructive pulmonary disease (COPD) prevalence is 2.1% in adults aged >40 years. Despite being a health policy focus, integrated COPD care has remained neglected, with wide variation in practice.AimTo assess whether enhanced care at public health facilities resulted in better control of COPD, treatment adherence, and smoking cessation.Design & settingA two-arm cluster randomised controlled trial was undertaken in 30 public health facilities (23 primary and 7 secondary), across three districts of Punjab, between October 2014–December 2016. Both arms had enhanced diagnosis and patient recording processes. Intervention facilities also had clinical care guides; drugs for COPD; patient education flipcharts; associated staff training; and mobile phone follow-up.MethodFacilities were randomised in a 1:1 ratio (sealed envelope independent lottery method), and 159 intervention and 154 control patients were recruited. The eligibility criteria were as follows: diagnosed with COPD, aged ≥18 years, and living in the catchment area. The primary outcome was change in BODE (Body mass index, airway Obstruction, Dyspnoea, Exercise capacity) index score from baseline to final follow-up visit. Staff and patients were not blinded.ResultsSix-month primary outcomes were available for 147/159 (92.5%) intervention and 141/154 (91.6%) control participants (all clusters). The primary outcome results cluster-level analysis were as follows: mean intervention outcome = -1.67 (95% confidence intervals [CI] = -2.18 to -1.16); mean control outcome = -0.66 (95% CI = -1.09 to -0.22); and covariate-adjusted mean intervention–control difference = -0.96 (95% CI = -1.49 to -0.44; P = 0.001).ConclusionThe findings of this trial and a separate process evaluation study support the scaling of this integrated COPD care package at primary and secondary level public health facilities in Pakistan and similar settings.
