Project description:BackgroundReaching the 90-90-90 targets requires efficient resource use to deliver HIV testing and treatment services. We investigated the costs and efficiency of HIV services in relation to HIV testing yield in rural Karonga District, Malawi.MethodsCosts of HIV services were measured over 12 months to September 2017 in five health facilities, drawing on recognised health costing principles. Financial and economic costs were collected in Malawi Kwacha and United States Dollars (US$). Costs were calculated using a provider perspective to estimate average annual costs (2017 US$) per HIV testing episode, per HIV-positive case diagnosed, and per patient-year on antiretroviral therapy (ART), by facility. Costs were assessed in relation to scale of operation and facility-level annual HIV positivity rate. A one-way sensitivity analysis was undertaken to understand how staffing levels and the HIV positivity rate affected HIV testing costs.ResultsHIV testing episodes per day and per full-time equivalent HIV health worker averaged 3.3 (range 2.0 to 5.7). The HIV positivity rate averaged 2.4% (range 1.9 to 3.7%). The average cost per testing episode was US$2.85 (range US$1.95 to US$8.55), and the average cost per HIV diagnosis was US$116.35 (range US$77.42 to US$234.11), with the highest costs found in facilities with the lowest daily number of tests and lowest HIV yield respectively. The mean facility-level cost per patient-year on ART was approximately US$100 (range US$90.67 to US$115.42). ART drugs were the largest cost component averaging 71% (range 55 to 76%). The cost per patient-year of viral load tests averaged US$4.50 (range US$0.52 to US$7.00) with cost variation reflecting differences in the tests to ART patient ratio across facilities.ConclusionGreater efficiencies in HIV service delivery are possible in Karonga through increasing daily testing episodes among existing health workers or allocating health workers to tasks in addition to testing. Costs per diagnosis will increase as yields decline, and therefore, encouraging targeted testing strategies that increase yield will be more efficient. Given the contribution of drug costs to per patient-year treatment costs, it is critical to preserve the life-span of first-line ART regimens, underlining the need for continuing adherence support and regular viral load monitoring.

Project description:Background: Providing HIV testing at health facilities remains the most common approach to ensuring access to HIV treatment and prevention services for the millions of undiagnosed HIV-infected individuals in sub-Saharan Africa. We sought to explore the costs of providing these services across three southern African countries with high HIV burden.Methods: Primary costing studies were undertaken in 54 health facilities providing HIV testing services (HTS) in Malawi, Zambia and Zimbabwe. Routinely collected monitoring and evaluation data for the health facilities were extracted to estimate the costs per individual tested and costs per HIV-positive individual identified. Costs are presented in 2016 US dollars. Sensitivity analysis explored key drivers of costs.Results: Health facilities were testing on average 2290 individuals annually, albeit with wide variations. The mean cost per individual tested was US$5.03.9 in Malawi, US$4.24 in Zambia and US$8.79 in Zimbabwe. The mean cost per HIV-positive individual identified was US$79.58, US$73.63 and US$178.92 in Malawi, Zambia and Zimbabwe respectively. Both cost estimates were sensitive to scale of testing, facility staffing levels and the costs of HIV test kits.Conclusions: Health facility based HIV testing remains an essential service to meet HIV universal access goals. The low costs and potential for economies of scale suggests an opportunity for further scale-up. However low uptake in many settings suggests that demand creation or alternative testing models may be needed to achieve economies of scale and reach populations less willing to attend facility based services.

Project description:ObjectiveTo review HIV testing services (HTS) costs in sub-Saharan Africa.DesignA systematic literature review of studies published from January 2006 to October 2020.MethodsWe searched ten electronic databases for studies that reported estimates for cost per person tested ($pptested) and cost per HIV-positive person identified ($ppositive) in sub-Saharan Africa. We explored variations in incremental cost estimates by testing modality (health facility-based, home-based, mobile-service, self-testing, campaign-style, and stand-alone), by primary or secondary/index HTS, and by population (general population, people living with HIV, antenatal care male partner, antenatal care/postnatal women and key populations). All costs are presented in 2019US$.ResultsSixty-five studies reported 167 cost estimates. Most reported only $pptested (90%), while (10%) reported the $ppositive. Costs were highly skewed. The lowest mean $pptested was self-testing at $12.75 (median = $11.50); primary testing at $16.63 (median = $10.68); in the general population, $14.06 (median = $10.13). The highest costs were in campaign-style at $27.64 (median = $26.70), secondary/index testing at $27.52 (median = $15.85), and antenatal male partner at $47.94 (median = $55.19). Incremental $ppositive was lowest for home-based at $297.09 (median = $246.75); primary testing $352.31 (median = $157.03); in the general population, $262.89 (median: $140.13).ConclusionWhile many studies reported the incremental costs of different HIV testing modalities, few presented full costs. Although the $pptested estimates varied widely, the costs for stand-alone, health facility, home-based, and mobile services were comparable, while substantially higher for campaign-style HTS and the lowest for HIV self-testing. Our review informs policymakers of the affordability of various HTS to ensure universal access to HIV testing.

Project description:Background:South Africa faces the highest burden of HIV infection globally. The National Strategic Plan on HIV recommends provider-initiated HIV counselling and testing (HCT) in all healthcare facilities. However, HIV continues to overwhelm the healthcare system. Emergency department (ED)-based HCT could address unmet testing needs. Objectives:This study examines the reasons for accepting or declining HCT in South African EDs to inform the development of HCT implementation strategies. Method:We conducted a prospective observational study in two rural EDs, from June to September 2017. Patients presenting to the ED were systematically approached and offered a point-of-care test in accordance with national guidelines. Patients demographics, presenting compaint, medical history and reasons for accepting/declining testing, were recorded. A pooled analysis is presented. Results:Across sites, 2074 adult, non-critical patients in the ED were approached; 1880 were enrolled in the study. Of those enrolled, 19.7% had a previously known positive diagnosis, and 80.3% were unaware of their HIV status. Of those unaware, 90% patients accepted and 10% declined testing. The primary reasons for declining testing were 'does not want to know status' (37.6%), 'in too much pain' (34%) and 'does not believe they are at risk' (19.9%). Conclusions:Despite national guidelines, a high proportion of individuals remain undiagnosed, of which a majority are young men. Our study demonstrated high patient acceptance of ED-based HCT. There is a need for investment and innovation regarding effective pain management and confidential service delivery to address patient barriers. Findings support a routine, non-targeted HCT strategy in EDs.

Project description:IntroductionMen in sub-Saharan Africa are less likely to use HIV testing services than their female counterparts. Norms of masculinity are frequently cited as the main barrier to men's use of HIV testing services, but very little is known about how health institutions are organized to facilitate or impede men's care. We examined the organization of health institutions in Malawi, and implications for men's use of HIV testing services.MethodsA mixed methods ethnography was conducted in Malawi between October 2013 and September 2014. National Ministry of Health guidelines from 2012 to 2014 were analysed, counting the frequency of recommended preventative services by sex. In-depth interviews were conducted with 18 healthcare workers and 11 national key informants (29 total). Five rural health facilities participated in direct observation and 52 observational journals were completed to document the structure and implementation of HIV services within local facilities. All data were analysed using the theory of gendered organization. Findings were grouped into one of the three theoretical levels of organization: (1) organizational policy; (2) organizational practice; and (3) structure of gendered expectations.ResultsHealth institutions were gendered across three levels. Organizational policy: National guidelines omitted young and adult men's health during reproductive years (176-433 recommended visits for women vs. 32 visits for men). Health education strategies focused on reproductive and child health services, with little education strategies targeting men. Organizational practice: HIV testing was primarily offered during reproductive and child health services and located near female-focused departments within health facilities. As these departments were women's spaces, others could easily tell that men were using HIV services. Structure of gendered expectations: Clients who successfully accessed HIV testing services were perceived as exemplifying characteristics that were traditionally considered feminine: compliance (obeying instructions without explanation); deference (respecting providers regardless of provider behaviour); and patience ("waiting like a woman").ConclusionsHealth institutions in Malawi were organized in ways that created substantial, multilevel barriers to men's HIV testing and reinforced perceptions of absent, difficult men. Future research should prioritize a gendered organization framework to understand and address the complex realities of men's constrained access to HIV services.

Project description:IntroductionHIV self-testing (HIVST) is an alternative strategy for reaching population subgroups underserved by available HIV testing services. We assessed individual factors associated with ever HIVST within a community-based program.SettingMalawi.MethodsWe conducted secondary analysis of an end line survey administered under a cluster-randomized trial of community-based distribution of HIVST kits. We estimated prevalence differences and prevalence ratios (PRs) stratified by sex for the outcome: self-reported ever HIVST.ResultsPrevalence of ever HIVST was 45.0% (475/1055) among men and 40.1% (584/1456) among women. Age was associated with ever HIVST in both men and women, with evidence of a strong declining trend across categories of age. Compared with adults aged 25-39 years, HIVST was lowest among adults aged 40 years and older for both men [34.4%, 121/352; PR 0.74, 95% confidence interval (CI): 0.62 to 0.88] and women (30.0%, 136/454; PR 0.71, 95% CI: 0.6 to 0.84). Women who were married, had children, had higher levels of education, or were wealthier were more likely to self-test. Men who had condomless sex in the past 3 months (47.9%, 279/582) reported a higher HIVST prevalence compared with men who did not have recent condomless sex (43.1%, 94/218; adjusted PR 1.37, 95% CI: 1.06 to 1.76). Among men and women, the level of previous exposure to HIV testing and household HIVST uptake was associated with HIVST.ConclusionsCommunity-based HIVST reached men, younger age groups, and some at-risk individuals. HIVST was lowest among older adults and individuals with less previous exposure to HIV testing, suggesting the presence of ongoing barriers to HIV testing.

Project description: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. TRIAL REGISTRATION:Clinicaltrials.gov registry ( NCT03541382 ) registered 30 May 2018.

Project description:BackgroundMalawi has made progress in increasing its overall modern contraceptive prevalence rate since 2000, resulting in a dramatic reduction in its total fertility rate. However, youth, 15-24 years, have not had the same successes. Teenage pregnancies are on the rise and little progress has been made in reducing unmet need for family planning among youth. With two-thirds of the population under the age of 25 and with Malawi's rapid population growth, reducing unmet need for family planning among youth remains a priority for the government's reproductive health agenda. To further explore this situation, we conducted a qualitative study to explore the perspectives of youth and adults about the drivers and barriers to youth accessing family planning in Malawi and their ideas to improve services.MethodsWe conducted 34 focus group discussions with youth aged 15-24 and parents or legal guardians of female youth in 3 districts in Malawi. Focus groups were translated and transcribed. Data was input into Dedoose and analyzed using a thematic framework to identify broader patterns and themes.ResultsYouth participants felt motivated to use family planning to protect themselves from sexually transmitted diseases and to prevent unwanted pregnancies. Females focused on the consequences of unplanned pregnancies and believed family planning services were targeted primarily at them, while males thought family planning services targeted males and females equally. Barriers to youth accessing family planning included contraception misconceptions, the costs of family planning services, and negative attitudes. Parents had mixed views on family planning. While many parents acknowledged they could play a role in supporting youth, most said they are reluctant to support youth using family planning. Participants said improving counseling services, integrating family planning services and education within school curricula, and utilizing youth clubs could improve family planning services for youth.ConclusionsPolicy makers and program implementers should consider the diverse preferences among youth and parents and continue seeking their input when designing policies and programs. Youth clubs and school-based services were among the most common suggestions. However, the effectiveness of youth clubs and school-based initiatives to increase contraceptive use among youth in Malawi is not clear.

Project description:Achieving the first 95 of the UNAIDS targets requires the implementation of innovative approaches to knowing one's HIV status. Among these innovations is the provision of HIV self-testing (HIVST) kits in west Africa by the international partner organization Solthis (IPO). In order to provide guidance for the optimal use of financial resources, this study aims to estimate the program and site level costs of dispensing HIVST as well as HIV testing services (HTS)-excluding HIVST-in health facilities in Côte d'Ivoire, Mali and Senegal as part of the ATLAS project. We estimated from the provider's perspective, HIVST and HTS incremental costs using top-down and bottom-up costing approaches and conducted a time and motion study. We identified costs at the program level for HIVST (including IPO central costs) and at the site level for HIVST and HTS. The economic costs of distributing HIVST kits were assessed in 37 health facilities between July 2019 and March 2021 (21 months). Sensitivity analyses were also performed on unit costs to examine the robustness of our estimates related to key assumptions. In total, 16,001 HIVST kits were dispensed for 32,194 HTS sessions carried out. Program level HIVST average costs ranged $12-286, whereas site level costs ranged $4-26 across distribution channels and countries. Site level HTS costs ranged $7-8 per testing session, and ranged $72-705 per HIV diagnosis. Across countries and channels, HIVST costs were driven by personnel (27-68%) and HIVST kits (32-73%) costs. The drivers of HTS costs were personnel costs ranging between 65 and 71% of total costs across distribution channels and countries, followed by supplies costs between 21 and 30%. While program level HIVST average costs were high, site level HIVST average costs remained comparable to HTS costs in all countries. Health facility-based distribution channels operating at low volume exhibit high proportion of central costs which should be considered carefully for financial planning when run alongside high volumes mobile outreach distribution channels. HIVST can diversify the HIV testing offer at health facilities, thus improving access to screening for target populations not reached by HTS services.

Project description:ObjectiveTo explore the experiences of cancer caregivers who live in rural Australia and travel to a metropolitan cancer health service to access cancer treatment.DesignA qualitative study using semistructured, audio-recorded interviews conducted between December 2017 and July 2018 with caregivers and social workers. Thematic analysis using interpretative descriptive techniques performed on textual interview data within a critical realist paradigm to develop understanding of rural caregivers' lived experiences.SettingParticipants were from rural areas attending a metropolitan cancer centre in Australia and social workers.Participants21 caregivers (16 female) of people with cancer living in rural Australia within a minimum distance of 100 km from the metropolitan cancer centre where they access treatment, and five social workers employed at a metropolitan cancer service with experience of working with rural patients and caregivers.ResultsThematic analysis developed two overarching themes: theme 1: caregiving in the rural setting describes the unique circumstance in which caregiving for a person with cancer takes place in the rural setting at considerable distance from the cancer service where the person receives treatment. This is explored in three categories: 'Rural community and culture', 'Life adjustments' and 'Available supports'. Theme 2: accessing metropolitan cancer services captures the multiplicity of tasks and challenges involved in organising and coordinating the journey to access cancer treatment in a metropolitan hospital, which is presented in the following categories: 'Travel', 'Accommodation' and 'Health system navigation'.ConclusionsCaregivers who live in rural areas face significant challenges when confronting geographic isolation between their rural home environment and the metropolitan setting, where the patient accessed cancer treatment. There is a need for healthcare services to identify this group to develop feasible and sustainable ways to provide interventions that have the best chance of assisting rural caregivers in supporting the patient while maintaining their own health and well-being.
