Optimising the cost and delivery of HIV counselling and testing services in Kenya and Swaziland.

ABSTRACT: BACKGROUND: Approaches to HIV counselling and testing (HCT) within low-resource high HIV prevalence settings have shifted over the years from primarily client-initiated approaches to provider initiated. As part of an ongoing programme science research agenda, we examine the relative costs of provider-initiated testing and counselling (PITC) services compared with voluntary counselling and testing (VCT) services in the same health facilities in two low-resource settings: Kenya and Swaziland. METHODS: Annual financial and economic costs and output measures were collected retrospectively from 28 health facilities. Total annual costs and average costs per client counselled and tested (C&T), and HIV-positive clients identified, were estimated. RESULTS: VCT remains the predominant mode of HCT service delivery across both countries. However, unit cost per client C&T and per person testing HIV positive is lower for PITC than VCT across all facility types in Kenya, but the picture is mixed in Swaziland. Average cost per client C&T ranged from US $4.81 to US $6.11 in Kenya, US $6.92 to US $13.51 in Swaziland for PITC, and from US $5.05 to US $16.05 and US $8.68 to US $19.32 for VCT in Kenya and Swaziland, respectively. CONCLUSIONS: In the context of significant policy interest in optimising scarce HIV resources, this study demonstrates that there may be potential for substantial gains in efficiency in the provision of HCT services in both Kenya and Swaziland. However, considerations of how to deliver services efficiently need to be informed by local contextual factors, such as prevalence, service demand and availability of human resources.

Project description:BACKGROUND: Health, fair financing and responsiveness to the user's needs and expectations are seen as the essential objectives of health systems. Efforts have been made to conceptualise and measure responsiveness as a basis for evaluating the non-health aspects of health systems performance. This study assesses the applicability of the responsiveness tool developed by WHO when applied in the context of voluntary HIV counselling and testing services (VCT) at a district level in Kenya. METHODS: A mixed method study was conducted employing a combination of quantitative and qualitative research methods concurrently. The questionnaire proposed by WHO was administered to 328 VCT users and 36 VCT counsellors (health providers). In addition to the questionnaire, qualitative interviews were carried out among a total of 300 participants. Observational field notes were also written. RESULTS: A majority of the health providers and users indicated that the responsiveness elements were very important, e.g. confidentiality and autonomy were regarded by most users and health providers as very important and were also reported as being highly observed in the VCT room. However, the qualitative findings revealed other important aspects related to confidentiality, autonomy and other responsiveness elements that were not captured by the WHO tool. Striking examples were inappropriate location of the VCT centre, limited information provided, language problems, and concern about the quality of counselling. CONCLUSION: The results indicate that the WHO developed responsiveness elements are relevant and important in measuring the performance of voluntary HIV counselling and testing. However, the tool needs substantial revision in order to capture other important dimensions or perspectives. The findings also confirm the importance of careful assessment and recognition of locally specific aspects when conducting comparative studies on responsiveness of HIV testing services.

Project description:The rapid scale-up of human immunodeficiency virus (HIV) testing, counselling and treatment throughout sub-Saharan Africa has raised questions about how to protect patients' rights to consent, confidentiality, counselling and care in resource-constrained settings. The Multi-country African Testing and Counselling for HIV (MATCH) study investigated client and provider experiences with different modes of testing in sub-Saharan Africa. One component of that study was a survey of 275 HIV service providers in Burkina Faso, Kenya and Uganda that gathered quantifiable indicators and qualitative descriptions using a standardized instrument. This article presents provider perspectives on the challenges of obtaining consent, protecting confidentiality, providing counselling and helping clients manage disclosure. It also explores health workers' fear of infection within the workplace and their reports on discrimination against HIV clients within health facilities. HIV care providers in Burkina Faso, Kenya and Uganda experienced substantial rewards from their work, including satisfaction from saving lives and gaining professional skills. They also faced serious resource constraints, including staff shortages, high workloads, lack of supplies and inadequate infrastructure, and they expressed concerns about accidental exposure. Health workers described heavy emotional demands from observing clients suffer emotional, social and health consequences of being diagnosed with HIV, and also from difficult ethical dilemmas related to clients who do not disclose their HIV status to those around them, including partners. These findings suggest that providers of HIV testing and counselling need more resources and support, including better protections against HIV exposure in the workplace. The findings also suggest that health facilities could improve care by increasing attention to consent, privacy and confidentiality and that health policy makers and ethicists need to address some unresolved ethical dilemmas related to confidentiality and non-disclosure, and translate those discussions into better guidance for health workers.

Project description:BackgroundHIV assisted partner services (aPS), or provider notification and testing for sexual and injecting partners of people diagnosed with HIV, is shown to be safe, effective, and cost-effective and was scaled up within the national HIV testing services (HTS) program in Kenya in 2016. We estimated the costs of integrating aPS into routine HTS within an ongoing aPS scale-up project in western Kenya.MethodsWe conducted microcosting using the payer perspective in 14 facilities offering aPS. Although aPS was offered to both males and females testing HIV-positive (index clients), we only collected data on female index clients and their male sex partners (MSP). We used activity-based costing to identify key aPS activities, inputs, resources, and estimated financial and economic costs of goods and services. We analyzed costs by start-up (August 2018), and recurrent costs one-year after aPS implementation (Kisumu: August 2019; Homa Bay: January 2020) and conducted time-and-motion observations of aPS activities. We estimated the incremental costs of aPS, average cost per MSP traced, tested, testing HIV-positive, and on antiretroviral therapy, cost shares, and costs disaggregated by facility.ResultsOverall, the number of MSPs traced, tested, testing HIV-positive, and on antiretroviral therapy was 1027, 869, 370, and 272 respectively. Average unit costs per MSP traced, tested, testing HIV-positive, and on antiretroviral therapy were $34.54, $42.50, $108.71 and $152.28, respectively, which varied by county and facility client volume. The weighted average incremental cost of integrating aPS was $7,485.97 per facility per year, with recurrent costs accounting for approximately 90% of costs. The largest cost drivers were personnel (49%) and transport (13%). Providers spent approximately 25% of the HTS visit obtaining MSP contact information (HIV-negative clients: 13 out of 54 min; HIV-positive clients: 20 out of 96 min), while the median time spent per MSP traced on phone and in-person was 6 min and 2.5 hours, respectively.ConclusionAverage facility costs will increase when integrating aPS to HTS with incremental costs largely driven by personnel and transport. Strategies to efficiently utilize healthcare personnel will be critical for effective, affordable, and sustainable aPS.

Project description:BackgroundFinding HIV infected persons and engaging them in care is crucial in achieving UNAIDS 90-90-90 targets; diagnosing 90% of those infected with HIV, initiating 90% of the diagnosed on ART and achieving viral suppression in 90% of those on ART. To achieve the first target, no person should be left behind in their access to HIV testing services. In Kenya, HIV prevention and testing services give less emphasis on older adults. This article describes HIV testing experiences of older adults living with HIV and how their age shaped their interaction and treatment received during HIV testing and diagnosis.MethodsWe conducted a qualitative study in two HIV clinics (rural and urban) in western Kenya, and recruited 57 HIV infected persons aged ≥50 years. We conducted in depth interviews (IDIs) with 25 participants and 4 focus group discussions (FGDs) with a total of 32 participants and audio recorded all the sessions. Participants recruited were aged between 54 and 79 years with 43% being females. We transcribed audio records and analyzed the data using thematic content analysis method.ResultsOlder persons' experiences with HIV testing depended on where they tested (hospital or community setting); whether they actively sought the testing or not; and the age and gender of the healthcare provider who conducted the test. Participants expressed concerns with ageist discrimination when actively seeking HIV care testing services in hospital settings, characterized by providers' reluctance or refusal to test. The testing and counseling sessions were described as short and hurried within the hospital settings, whereas the interactions with service providers in home-based testing were experienced as appropriate and supportive. Participants in this study expressed preference for healthcare providers who were older and of similar gender.ConclusionHIV testing services are still not tailored to target older adults' needs in our setting resulting in late diagnosis among older persons. We argue that a scale-up of community level testing services that provide adequate testing and counselling time and actively reach out to older adults is key to attaining the UNAIDS targets of having 90% of PLWH know their status.

Project description:BackgroundThe elicitation of contact information, notification and testing of sex partners of HIV infected patients (aPS), is an effective HIV testing strategy in low-income settings but may not necessarily be affordable. We applied WHO guidelines and the International Society for Pharmaco-economics and Outcomes Research (ISPOR) guidelines to conduct cost and budget impact analyses, respectively, of aPS compared to current practice of HIV testing services (HTS) in Kisumu County, Kenya.MethodsUsing study data and time motion studies, we constructed an Excel-based tool to estimate costs and the budget impact of aPS. Cost data were collected from selected facilities in Kisumu County. We report the annual total and unit costs of HTS, incremental total and unit costs for aPS, and the budget impact of scaling up aPS over a 5-year horizon. We also considered a task-shifted scenario that used community health workers (CHWs) rather than facility based health workers and conducted sensitivity analyses assuming different rates of scale up of aPS.ResultsThe average unit costs for HIV testing among HIV-infected index clients was US$ 25.36 per client and US$ 17.86 per client using nurses and CHWs, respectively. The average incremental costs for providing enhanced aPS in Kisumu County were US$ 1,092,161 and US$ 753,547 per year, using nurses and CHWs, respectively. The average incremental cost of scaling up aPS over a five period was 45% higher when using nurses compared to using CHWs (US$ 5,460,837 and US$ 3,767,738 respectively). Over the five years, the upper-bound budget impact of nurse-model was US$ 1,767,863, 63% and 35% of which were accounted for by aPS costs and ART costs, respectively. The CHW model incurred an upper-bound incremental cost of US$ 1,258,854, which was 71.2% lower than the nurse-based model. The budget impact was sensitive to the level of aPS coverage and ranged from US$ 28,547 for 30% coverage using CHWs in 2014 to US$ 1,267,603 for 80% coverage using nurses in 2018.ConclusionScaling aPS using nurses has minimal budget impact but not cost-saving over a five-year period. Targeting aPS to newly-diagnosed index cases and task-shifting to community health workers is recommended.

Project description:Background: HIV drug resistance (HIVDR) threatens progress achieved in response to the HIV epidemic. Understanding the costs of implementing HIVDR testing programs for patient management and surveillance in resource-limited settings is critical in optimizing resource allocation. Here, we estimate the unit cost of HIVDR testing and identify major cost drivers while documenting challenges and lessons learnt in implementation of HIVDR testing at a tertiary level hospital in Kenya. Methods: We employed a mixed costing approach to estimate the costs associated with performing a HIVDR test from the provider's perspective. Data collection involved a time and motion study of laboratory procedures and interviewing laboratory personnel and the management personnel. Cost analysis was based on estimated 1000 HIVDR tests per year. Data entry and analysis were done using Microsoft Excel and costs converted to US dollars (2019). Results: The estimated unit cost for a HIVDR test was $271.78 per test. The main cost drivers included capital ($102.42, 37.68%) and reagents (101.50, 37.35%). Other costs included: personnel ($46.81, 17.22%), utilities ($14.69, 5.41%), equipment maintenance costs ($2.37, 0.87%) and quality assurance program ($4, 1.47%). Costs in relation to specific laboratory processes were as follows: sample collection ($2.41, 0.89%), RNA extraction ($22.79, 8.38%), amplification ($56.14, 20.66%), gel electrophoresis ($10.34, 3.80%), sequencing ($160.94, 59.22%), and sequence analysis ($19.16, 7.05%). A user-initiated modification of halving reagent volumes for some laboratory processes (amplification and sequencing) reduced the unit cost for a HIVDR test to $233.81 (13.97%) reduction. Conclusions: Capital expenditure and reagents remain the most expensive components of HIVDR testing. This cost is bound to change as the sequencing platform is utilized towards maximum capacity or leveraged for use with other tests. Cost saving in offering HIVDR testing services is also possible through reagent volume reduction without compromising on the quality of test results.

Project description:BACKGROUND:Couples HIV Testing & Counselling (CHTC) service is an approach that may enable more people to be reached and tested for HIV. However, little is known about how couples may use this service and what they think about CHTC as an approach to finding out their HIV status. This study aimed to understand how individuals who had ever been in an ongoing heterosexual relationship for 6 months or more intended to use CHTC in Ethiopia and their beliefs about its benefits and potential harms. METHODS:Qualitative in-depth interviews were conducted in Addis Ababa, the capital city of Ethiopia, in 2017. Semi-structured interviews were undertaken with individuals who had ever been in an ongoing heterosexual relationship (n = 21) and key-informants (n = 11) including religious leaders, health care providers, and case managers. The interviews were transcribed verbatim, and an inductive thematic analysis was conducted. The data were coded to look for concepts and patterns across the interviews and relevant themes identified which captured key aspects related to the individual's views on undertaking HIV testing with a sexual partner. RESULTS:Most participants regarded CHTC as an important HIV testing approach for people who are in an ongoing heterosexual relationship and expressed the view that there was "nothing like testing together". However, many of the individual participants revealed they would prefer first to get tested alone to find out their own HIV status. They feared the consequences if they were HIV-positive, including accusations of infidelity, relationship break-up, and being exposed in the community. Many also reported being pressured to undertake CHTC before marriage by a third party, including religious institutions. Key informant interviews also discussed the requirements for CHTC before marriage. CONCLUSION:The findings of this study suggest that people may be concerned about undertaking couples HIV testing without prior individual HIV testing. The intention of many to first test alone has policy and cost implications and underscores the possible harms of the implementation of CHTC in Ethiopia. Future research should examine whether the views identified in this qualitative study are reflected more broadly among couples in the community.
