5-SPICE: the application of an original framework for community health worker program design, quality improvement and research agenda setting

Introduction Despite decades of experience with community health workers (CHWs) in a wide variety of global health projects, there is no established conceptual framework that structures how implementers and researchers can understand, study and improve their respective programs based on lessons learned by other CHW programs. Objective To apply an original, non-linear framework and case study method, 5-SPICE, to multiple sister projects of a large, international non-governmental organization (NGO), and other CHW projects. Design Engaging a large group of implementers, researchers and the best available literature, the 5-SPICE framework was refined and then applied to a selection of CHW programs. Insights gleaned from the case study method were summarized in a tabular format named the ‘5×5-SPICE chart’. This format graphically lists the ways in which essential CHW program elements interact, both positively and negatively, in the implementation field. Results The 5×5-SPICE charts reveal a variety of insights that come from a more complex understanding of how essential CHW projects interact and influence each other in their unique context. Some have been well described in the literature previously, while others are exclusive to this article. An analysis of how best to compensate CHWs is also offered as an example of the type of insights that this method may yield. Conclusions The 5-SPICE framework is a novel instrument that can be used to guide discussions about CHW projects. Insights from this process can help guide quality improvement efforts, or be used as hypothesis that will form the basis of a programs research agenda. Recent experience with research protocols embedded into successfully implemented projects demonstrates how such hypothesis can be rigorously tested.

Crossing the quality chasm in resource-limited settings.

Over the last decade, extensive scientific and policy innovations have begun to reduce the “quality chasm” - the gulf between best practices and actual implementation that exists in resource-rich medical settings. While limited data exist, this chasm is likely to be equally acute and deadly in resource-limited areas. While health systems have begun to be scaled up in impoverished areas, scale-up is just the foundation necessary to deliver effective healthcare to the poor. This perspective piece describes a vision for a global quality improvement movement in resource-limited areas. The following action items are a first step toward achieving this vision: 1) revise global health investment mechanisms to value quality; 2) enhance human resources for improving health systems quality; 3) scale up data capacity; 4) deepen community accountability and engagement initiatives; 5) implement evidence-based quality improvement programs; 6) develop an implementation science research agenda.

Strengthening Nepal's Female Community Health Volunteer network: a qualitative study of experiences at two years

BackgroundNepal’s Female Community Health Volunteer (FCHV) program has been described as an exemplary public-sector community health worker program. However, despite its merits, the program still struggles to provide high-quality, accessible services nation-wide. Both in Nepal and globally, best practices for community health worker program implementation are not yet known: there is a dearth of empiric research, and the research that has been done has shown inconsistent results.MethodsHere we evaluate a pilot program designed to strengthen the Nepali government’s FCHV network. The program was structured with five core components: 1) improve local FCHV leadership; 2) facilitate structured weekly FCHV meetings and 3) weekly FCHV trainings at the village level; 4) implement a monitoring and evaluation system for FCHV patient encounters; and 5) provide financial compensation for FCHV work. Following twenty-four months of program implementation, a retrospective programmatic evaluation was conducted, including qualitative analysis of focus group discussions and semi-structured interviews.ResultsQualitative data analysis demonstrated that the program was well-received by program participants and community members, and suggests that the five core components of this program were valuable additions to the pre-existing FCHV network. Analysis also revealed key challenges to program implementation including geographic limitations, literacy limitations, and limitations of professional respect from healthcare workers to FCHVs. Descriptive statistics are presented for programmatic process metrics and costs throughout the first twenty four months of implementation.ConclusionsThe five components of this pilot program were well-received as a mechanism for strengthening Nepal’s FCHV program. To our knowledge, this is the first study to present such data, specifically informing programmatic design and management of the FCHV program. Despite limitations in its scope, this study offers tangible steps forward for further research and community health worker program improvement, both within Nepal and globally.

Implementing surgical services in a rural, resource-limited setting: A study protocol

Introduction There are well-established protocols and procedures for the majority of common surgical diseases, yet surgical services remain largely inaccessible for much of the worlds rural poor. Data on the process and outcome of surgical care expansion, however, are very limited, and the roll-out process of rural surgical implementation in particular has never been studied. Here, we propose the first implementation research study to assess the surgical scale-up process in the rural district of Achham, Nepal. Methods and analysis Based primarily on the protocols of the WHOs Integrated Management for Emergency and Essential Surgical Care (IMEESC), this studys threefold implementation strategy will include: (1) the core IMEESC surgical care program, (2) community-based follow-up via health workers, and (3) hospital-based quality improvement programs. The implementation program will employ additional emergency and surgical care protocols developed collaboratively by physicians, nurses and the authors. This strategy will be referred to as IMEESC-Plus. This study will employ both qualitative and quantitative research methodologies to collect clinical data and information on the reception and utilisation of services. The first 18 months of the implementation process will be studied and divided into an initial phase (first 6 months) and a consolidation phase (subsequent 12 months). Discussion This study aims to describe the logistics of the implementation process of IMEESC-Plus, and assess the quality of the resulting IMEESC-Plus services during the course of the implementation process. Using data generated from this study, larger, multi-site implementation studies can be planned that assess the scale-up of surgical services worldwide in resource-limited areas.

Visceral Leishmaniasis in Far Western Nepal: Another Case and Concerns about a New Area of Endemicity

Dear Sir: Pandey and others reported the first case of visceral leishmaniasis (VL) in the Far Western Hills region of Nepal.1 At our hospital in the Achham district, which neighbors the Doti district described in the Pandey and others report, we recently had a case of VL in a 17-year-old woman who presented with advanced disease. We transferred her to a hospital in Kathmandu where she received amphotericin and required intensive care, but unfortunately ultimately succumbed to her illness. Like the patient Pandey and others described, our patient had never traveled to known VL-endemic areas. As the authors pointed out, VL has been thought to be limited to south-eastern Nepal, far from where these cases occurred. It is possible that these cases were due to Leishmania infantum, which has a canine reservoir and has been seen in Himachal Pradesh in India, Pakistan, and throughout Central Asia.2,3 However, it is also possible that the Phlebotomine sandfly is making inroads in other parts of Nepal, and with it Leishmania donovani. With climate change, we have seen other vector-borne diseases spreading to new areas. Dengue was first seen in southern Nepal in 2004 and has moved north to Kathmandu, where Aedes aegypti was not previously seen.4,5 Given extreme poverty and poor healthcare infrastructure in the remote western part of Nepal, passive case detection for VL may be inadequate for surveillance. To achieve the goal of VL eradication agreed upon by the governments of Nepal, India, and Bangladesh, we concur with Pandey and others that active surveillance in Nepal should be urgently expanded.

Design and implementation of an affordable, public sector electronic medical record in rural Nepal

Introduction Globally, electronic medical records are central to the infrastructure of modern healthcare systems. Yet, the vast majority of electronic medical records have been designed for resource-rich environments and are not feasible in settings of poverty. Here, we describe the design and implementation of an electronic medical record at a public sector district hospital in rural Nepal and its subsequent expansion to an additional public sector facility. Development The electronic medical record was designed to solve for the following elements of public sector healthcare delivery: 1) integration of the systems across inpatient, surgical, outpatient, emergency, laboratory, radiology and pharmacy sites of care; 2) effective data extraction for impact evaluation and government regulation; 3) optimization for longitudinal care provision and patient tracking and 4) effectiveness for quality improvement initiatives. Application For these purposes, we adapted Bahmni, a product built with open-source components for patient tracking, clinical protocols, pharmacy, laboratory, imaging, financial management and supply logistics. In close partnership with government officials, we deployed the system in February of 2015, added on additional functionality and iteratively improved the system over the following year. This experience enabled us then to deploy the system at an additional district-level hospital in a different part of the country in under four weeks. We discuss the implementation challenges and the strategies we pursued to build an electronic medical record for the public sector in rural Nepal. Discussion Over the course of 18 months, we were able to develop, deploy and iterate upon the electronic medical record, and then deploy the refined product at an additional facility within only four weeks. Our experience suggests the feasibility of an integrated electronic medical record for public sector care delivery even in settings of rural poverty.

Highly active anti-retroviral therapy in the prevention of mother-to-child transmission of HIV in rural Zimbabwe during the socio-economic crisis

The purpose of this study is to evaluate the effectiveness of highly active antiretroviral therapy (HAART) in preventing mother-to-child transmission (PMTCT) of HIV in breastfeeding women in rural Zimbabwe. During a severe socio-economic crisis in 2005–2007, 82 eligible HIV-positive pregnant women between 14–36 weeks gestation were initiated on HAART with AZT/3TC/nelfinavir combination therapy at a rural hospital and continued through to six months post-partum. In addition, mothers also received intrapartum single-dose nevirapine (sdNVP). Infants received sdNVP/AZT in the first 72 hours and were assessed for HIV infection at six weeks of age. Results were compared to historical controls of HIV-positive pregnant women who received sdNVP only at the same center. Of the 67 infants with available data on HIV status at six weeks postpartum, three (4.4%) were HIV positive by HIV RNA assay in the HAART + sdNVP group compared to 49/297 (16.5%) in the sdNVP group (p = 0.01). HAART given to HIV-infected mothers in pregnancy and during breastfeeding along with intrapartum sdNVP resulted in a lower postnatal HIV transmission at six weeks postpartum compared to sdNVP treatment. Our HAART regimen demonstrates that PMTCT of HIV can be effective even during times of socio-economic crisis in resource-poor rural settings.

Combining Healthcare-Based and Participatory Approaches to Surveillance: Trends in Diarrheal and Respiratory Conditions Collected by a Mobile Phone System by Community Health Workers in Rural Nepal

Background Surveillance systems are increasingly relying upon community-based or crowd-sourced data to complement traditional facilities-based data sources. Data collected by community health workers during the routine course of care could combine the early warning power of community-based data collection with the predictability and diagnostic regularity of facility data. These data could inform public health responses to epidemics and spatially-clustered endemic diseases. Here, we analyze data collected on a daily basis by community health workers during the routine course of clinical care in rural Nepal. We evaluate if such community-based surveillance systems can capture temporal trends in diarrheal diseases and acute respiratory infections. Methods During the course of their clinical activities from January to December 2013, community health workers recorded healthcare encounters using mobile phones. In parallel, we accessed condition-specific admissions from 2011–2013 in the hospital from which the community health program was based. We compared diarrhea and acute respiratory infection rates from both the hospital and the community, and assigned three categories of local disease activity (low, medium, and high) to each week in each village cluster with categories determined by tertiles. We compared condition-specific mean hospital rates across categories using ANOVA to assess concordance between hospital and community-collected data. Results There were 2,710 cases of diarrhea and 373 cases of acute respiratory infection reported by community health workers during the one-year study period. At the hospital, the average weekly incidence of diarrhea and acute respiratory infections over the three-year period was 1.8 and 3.9 cases respectively per 1,000 people in each village cluster. In the community, the average weekly rate of diarrhea and acute respiratory infections was 2.7 and 0.5 cases respectively per 1,000 people. Both diarrhea and acute respiratory infections exhibited significant differences between the three categories of disease rate burden (diarrhea p = 0.009, acute respiratory infection p = 0.001) when comparing community health worker-collected rates to hospital rates. Conclusion Community-level data on diarrhea and acute respiratory infections modestly correlated with hospital data for the same condition in each village each week. Our experience suggests that community health worker-collected data on mobile phones may be a feasible adjunct to other community- and healthcare-related data sources for surveillance of such conditions. Such systems are vitally needed in resource-limited settings like rural Nepal.

Protection from UV light is an evolutionarily conserved feature of the haematopoietic niche

Haematopoietic stem and progenitor cells (HSPCs) require a specific microenvironment, the haematopoietic niche, which regulates HSPC behaviour1,2. The location of this niche varies across species, but the evolutionary pressures that drive HSPCs to different microenvironments remain unknown. The niche is located in the bone marrow in adult mammals, whereas it is found in other locations in non-mammalian vertebrates, for example, in the kidney marrow in teleost fish. Here we show that a melanocyte umbrella above the kidney marrow protects HSPCs against ultraviolet light in zebrafish. Because mutants that lack melanocytes have normal steady-state haematopoiesis under standard laboratory conditions, we hypothesized that melanocytes above the stem cell niche protect HSPCs against ultraviolet-light-induced DNA damage. Indeed, after ultraviolet-light irradiation, unpigmented larvae show higher levels of DNA damage in HSPCs, as indicated by staining of cyclobutane pyrimidine dimers and have reduced numbers of HSPCs, as shown by cmyb (also known as myb) expression. The umbrella of melanocytes associated with the haematopoietic niche is highly evolutionarily conserved in aquatic animals, including the sea lamprey, a basal vertebrate. During the transition from an aquatic to a terrestrial environment, HSPCs relocated into the bone marrow, which is protected from ultraviolet light by the cortical bone around the marrow. Our studies reveal that melanocytes above the haematopoietic niche protect HSPCs from ultraviolet-light-induced DNA damage in aquatic vertebrates and suggest that during the transition to terrestrial life, ultraviolet light was an evolutionary pressure affecting the location of the haematopoietic niche.Melanocytes above the haematopoietic niche protect haematopoietic stem cells from ultraviolet-light-induced DNA damage in aquatic vertebrates throughout evolution; this niche moved to the bone marrow during the transition to terrestrial life.

Power, potential, and pitfalls in global health academic partnerships: review and reflections on an approach in Nepal

ABSTRACT Background: Global health academic partnerships are centered around a core tension: they often mirror or reproduce the very cross-national inequities they seek to alleviate. On the one hand, they risk worsening power dynamics that perpetuate health disparities; on the other, they form an essential response to the need for healthcare resources to reach marginalized populations across the globe. Objectives: This study characterizes the broader landscape of global health academic partnerships, including challenges to developing ethical, equitable, and sustainable models. It then lays out guiding principles of the specific partnership approach, and considers how lessons learned might be applied in other resource-limited settings. Methods: The experience of a partnership between the Ministry of Health in Nepal, the non-profit healthcare provider Possible, and the Health Equity Action and Leadership Initiative at the University of California, San Francisco School of Medicine was reviewed. The quality and effectiveness of the partnership was assessed using the Tropical Health and Education Trust Principles of Partnership framework. Results: Various strategies can be taken by partnerships to better align the perspectives of patients and public sector providers with those of expatriate physicians. Actions can also be taken to bring greater equity to the wealth and power gaps inherent within global health academic partnerships. Conclusions: This study provides recommendations gleaned from the analysis, with an aim towards both future refinement of the partnership and broader applications of its lessons and principles. It specifically highlights the importance of targeted engagements with academic medical centers and the need for efficient organizational work-flow practices. It considers how to both prioritize national and host institution goals, and meet the career development needs of global health clinicians.
