Innovation in Evaluating the Impact of Integrated Service-Delivery: The Integra Indexes of HIV and Reproductive Health Integration.

ABSTRACT: BACKGROUND:The body of knowledge on evaluating complex interventions for integrated healthcare lacks both common definitions of 'integrated service delivery' and standard measures of impact. Using multiple data sources in combination with statistical modelling the aim of this study is to develop a measure of HIV-reproductive health (HIV-RH) service integration that can be used to assess the degree of service integration, and the degree to which integration may have health benefits to clients, or reduce service costs. METHODS AND FINDINGS:Data were drawn from the Integra Initiative's client flow (8,263 clients in Swaziland and 25,539 in Kenya) and costing tools implemented between 2008-2012 in 40 clinics providing RH services in Kenya and Swaziland. We used latent variable measurement models to derive dimensions of HIV-RH integration using these data, which quantified the extent and type of integration between HIV and RH services in Kenya and Swaziland. The modelling produced two clear and uncorrelated dimensions of integration at facility level leading to the development of two sub-indexes: a Structural Integration Index (integrated physical and human resource infrastructure) and a Functional Integration Index (integrated delivery of services to clients). The findings highlight the importance of multi-dimensional assessments of integration, suggesting that structural integration is not sufficient to achieve the integrated delivery of care to clients--i.e. "functional integration". CONCLUSIONS:These Indexes are an important methodological contribution for evaluating complex multi-service interventions. They help address the need to broaden traditional evaluations of integrated HIV-RH care through the incorporation of a functional integration measure, to avoid misleading conclusions on its 'impact' on health outcomes. This is particularly important for decision-makers seeking to promote integration in resource constrained environments.

Project description:The lack of human resources is a key challenge in scaling up of HIV services in Africa's health care system. Integrating HIV services could potentially increase their effectiveness and optimize the use of limited resources and clinical staff time. We examined the impact of integration of provider initiated HIV counselling and testing (PITC) and family planning (FP counselling and FP provision) services on duration of consultation to assess the impact of PITC and FP integration on staff workload. This study was conducted in 24 health facilities in Kenya under the Integra Initiative, a non-randomized, pre/post intervention trial to evaluate the impact of integrated HIV and sexual and reproductive health services on health and service outcomes. We compared the time spent providing PITC-only services, FP-only services and integrated PITC/FP services. We used log-linear regression to assess the impact of plausible determinants on the duration of clients' consultation times. Median consultation duration times were highest for PITC-only services (30?min), followed by integrated services (10?min) and FP-only services (8?min). Times for PITC-only and FP-only services were 69.7% higher (95% Confidence Intervals (CIs) 35.8-112.0) and 43.9% lower (95% CIs -55.4 to?-?29.6) than times spent on these services when delivered as an integrated service, respectively. The reduction in consultation times with integration suggests a potential reduction in workload. The higher consultation time for PITC-only could be because more pre- and post-counselling is provided at these stand-alone services. In integrated PITC/FP services, the duration of the visit fell below that required by HIV testing guidelines, and service mix between counselling and testing substantially changed. Integration of HIV with FP services may compromise the quality of services delivered and care must be taken to clearly specify and monitor appropriate consultation duration times and procedures during the process of integrating HIV and FP services.

Project description:Drawing on rich data from the Integra evaluation of integrated HIV and reproductive-health services, we explored the interaction of systems hardware and software factors to explain why some facilities were able to implement and sustain integrated service delivery while others were not. This article draws on detailed mixed-methods data for four case-study facilities offering reproductive-health and HIV services between 2009 and 2013 in Kenya: (i) time-series client flow, tracking service uptake for 8841 clients; (ii) structured questionnaires with 24 providers; (iii) in-depth interviews with 17 providers; (iv) workload and facility data using a periodic activity review and cost-instruments; and (v) contextual data on external activities related to integration in study sites. Overall, our findings suggested that although structural factors like stock-outs, distribution of staffing and workload, rotation of staff can affect how integrated care is provided, all these factors can be influenced by staff themselves: both frontline and management. Facilities where staff displayed agency of decision making, worked as a team to share workload and had management that supported this, showed better integration delivery and staff were able to overcome some structural deficiencies to enable integrated care. Poor-performing facilities had good structural integration, but staff were unable to utilize this because they were poorly organized, unsupported or teams were dysfunctional. Conscientious objection and moralistic attitudes were also barriers.Integra has demonstrated that structural integration is not sufficient for integrated service delivery. Rather, our case studies show that in some cases excellent leadership and peer-teamwork enabled facilities to perform well despite resource shortages. The ability to provide support for staff to work flexibly to deliver integrated services and build resilient health systems to meet changing needs is particularly relevant as health systems face challenges of changing burdens of disease, climate change, epidemic outbreaks and more.

Project description:Objectives There were 2 main objectives. The primary objective was to replicate a prior clinical trial of a consumer-decides (CD) approach to selecting hearing aids in older adults as a potential model for over-the-counter (OTC) intervention using less front-end screening of participants and a wider range of frequency-gain characteristics in the devices. The 2nd objective, only feasible if participant choices allowed, was to evaluate the efficacy of the CD approach relative to a CD-based placebo device. Design The design of this study is a single-site, prospective, double-blind clinical trial. Outcome measures were obtained after a typical 4- to 5-week trial period. An optional follow-up of a 4-week audiology-based (AB) best practices trial was also included for replication and comparison purposes. Setting Older adults from the general community were recruited via newspaper and community flyers to participate at a university research clinic. Participants Participants were adults, aged 54-78 years, with mild-moderate hearing loss. Forty-one participants enrolled as a volunteer sample; 40 completed the intervention. Intervention(s) All participants received the same high-end digital mini-behind-the-ear hearing aids fitted bilaterally. CD participants self-selected their own preprogrammed hearing aids via an OTC-type model. One of the 3 devices from which participants could choose was programmed to be a placebo device with no functional gain. Primary and Secondary Outcome Measures The primary outcome measure is the 66-item self-report Profile of Hearing Aid Benefit ( Cox & Alexander, 1990 ). The secondary outcome measure is the Connected Speech Test ( Cox, Alexander, & Gilmore, 1987 ) benefit. Additional measures of hearing aid benefit and usage were also obtained. Results Per-protocol analyses based on the data from the 40 (of 41) participants who completed the study were performed. Hearing aid outcomes from this follow-up CD (CD2) cohort were positive and generally the same as for the original CD cohort. CD service delivery model was efficacious relative to CD-based placebo control, with medium effect sizes observed. Approximately half of the CD2 group was likely to purchase hearing aids after the trial, similar to findings for the original CD cohort. Outcomes improved significantly for the 32 CD2 participants who elected to complete the optional 4-week AB trial. For this largely unscreened sample, more individuals with healthy hearing sought amplification, and many of these individuals (35%) chose placebo devices for both ears. Conclusions Prior positive outcomes for CD service delivery have been replicated in a less restrictive approach to participant recruitment. The CD approach was again found to be efficacious. Significantly better outcomes were observed after subsequent AB service delivery follow-up, also replicating prior findings. Efficacious OTC models, including those using similar CD approaches to hearing aid self-selection, may increase accessibility and affordability of hearing aids for millions of older adults. Front-end guidance to consumers regarding the best path to intervention, ranging from self-screening of hearing online to a full audiologic assessment, appears to be critical to optimize the success of OTC approaches.

Project description:BackgroundNorthwest Syria (NWS) is a complex and extremely fragile operating environment, with more than 2.8 million people needing humanitarian assistance. To support a common standard of care delivery and enable coordination among the multiple providers in NWS, WHO developed an Essential Health Services package (EHSP) in 2016-17 and subsequently supported a facility network model to deliver the EHSP. This article provides an evaluation of the network to date, aiming to inform further development of the network and draw wider lessons for application of similar approaches in complex emergency settings.MethodsThis mixed method study included document review, participatory, qualitative and quantitative data, gathered in the first half of 2021. Participatory data came from two group model building workshops with 21 funders and implementers. Semi-structured interviews with 81 funders, health professionals and community members were also conducted. Analyses of the workshops and interviews was inductive, however a deductive approach was used for synthesising insights across this and the document review. The final component was a survey of health providers (59 health care professionals) and service users (233 pregnant women and 214 persons living with NCDs) across network and other comparable facilities, analysed using routine descriptive and inferential statistics. Findings across all methods were triangulated.ResultsThe study finds that the network and its accompanying essential service package were relevant to the dynamic and challenging context, with high but shifting population needs and multiple uncoordinated providers. Judged in relation to its original goals of comprehensive, coordinated services, equitable access and efficient service delivery, the data indicate that gains have been made in all three areas through the network, although attribution is challenging, given the complex environment. The context remains challenging, with shifting boundaries and populations displaced by conflict, difficulties in retaining staff, the need to import medicines and supplies across borders, and governance gaps.ConclusionThis study adds to a very limited literature on coordinated network approaches used to raise care quality and improve referrals and efficiency in a complex emergency setting. Although areas of ongoing challenge, including for sustainability, are noted, the network demonstrated some resilience strategies and can provide lessons for other similar contexts.
