Can they get along without us? Sustainability of donor-supported health projects in Central America and Africa

This article presents a synthesis of five country studies of the sustainability of U.S. government-funded health projects in Central America and Africa. The studies reviewed health projects with a comparative framework to determine which project activities had continued after the donor funding ceased. This review found that health projects in Africa were less firmly sustained than those in Central America. The studies then evaluated context factors and project characteristics that were related to the sustainability of the projects. The weak economic and political context of the African cases was found to inhibit sustainability in those countries, suggesting that broader development issues be addressed before donors expect significant sustainability of health projects in Africa. Even in Central America it was found that the strength of the institution implementing the project was an important variable for sustainability, suggesting that donor attention also be shifted toward strengthening institutional development in order to assure sustainability. In addition to context factors, several project characteristics were related to sustainability in most cases and suggest sustainability guidelines for project design and implementation. The article concludes that projects should be designed and managed so as to: (1) demonstrate effectiveness in reaching clearly defined goals and objectives; (2) integrate their activities fully into established administrative structures; (3) gain significant levels of funding from national sources (budgetary and cost-recovery) during the life of the project; (4) negotiate project design with a mutually respectful process of give and take: and (5) include a strong training component.

Effectiveness of diabetes and hypertension management by rural primary health-care workers (Behvarz workers) in Iran: a nationally representative observational study.

BACKGROUND Non-communicable diseases and their risk factors are leading causes of disease burden in Iran and other middle-income countries. Little evidence exists for whether the primary health-care system can effectively manage non-communicable diseases and risk factors at the population level. Our aim was to examine the effectiveness of the Iranian rural primary health-care system (the Behvarz system) in the management of diabetes and hypertension, and to assess whether the effects depend on the number of health-care workers in the community. METHODS We used individual-level data from the 2005 Non-Communicable Disease Surveillance Survey (NCDSS) for fasting plasma glucose (FPG) and systolic blood pressure (SBP), body-mass index, medication use, and sociodemographic variables. Data for Behvarz-worker and physician densities were from the 2006 Population and Housing Census and the 2005 Outpatient Care Centre Mapping Survey. We assessed the effectiveness of treatment on FPG and SBP, and associations between FPG or SBP and Behvarz-worker density with two statistical approaches: a mixed-effects regression analysis of the full NCDSS sample adjusting for individual-level and community-level covariates and an analysis that estimated average treatment effect on data balanced with propensity score matching. RESULTS NCDSS had data for 65,619 individuals aged 25 years or older (11,686 of whom in rural areas); of these, 64,694 (11,521 in rural areas) had data for SBP and 50,202 (9337 in rural areas) had data for FPG. Nationally, 39·2% (95% CI 37·7 to 40·7) of individuals with diabetes and 35·7% (34·9 to 36·5) of those with hypertension received treatment, with higher treatment coverage in women than in men and in urban areas than in rural areas. Treatment lowered mean FPG by an estimated 1·34 mmol/L (0·58 to 2·10) in rural areas and 0·21 mmol/L (-0·15 to 0·56) in urban areas. Individuals in urban areas with hypertension who received treatment had 3·8 mm Hg (3·1 to 4·5) lower SBP than they would have had if they had not received treatment; the treatment effect was 2·5 mm Hg (1·1 to 3·9) lower FPG in rural areas. Each additional Behvarz worker per 1000 adults was associated with a 0·09 mmol/L (0·01 to 0·18) lower district-level average FPG (p=0·02); for SBP this effect was 0·53 mm Hg (-0·44 to 1·50; p=0·28). Our findings were not sensitive to the choice of statistical method. INTERPRETATION Primary care systems with trained community health-care workers and well established guidelines can be effective in non-communicable disease prevention and management. Irans primary care system should expand the number and scope of its primary health-care worker programmes to also address blood pressure and to improve performance in areas with few primary care personnel. FUNDING None.

The health-care system: an assessment and reform agenda

Attempts to establish a health plan for the occupied Palestinian territory were made before the 1993 Oslo Accords. However, the first official national health plan was published in 1994 and aimed to regulate the health sector and integrate the activities of the four main health-care providers: the Palestinian Ministry of Health, Palestinian non-governmental organisations, the UN Relief and Works Agency, and a cautiously developing private sector. However, a decade and a half later, attempts to create an effective, efficient, and equitable system remain unsuccessful. This failure results from arrangements for health care established by the Israeli military government between 1967 and 1994, the nature of the Palestinian National Authority, which has little authority in practice and has been burdened by inefficiency, cronyism, corruption, and the inappropriate priorities repeatedly set to satisfy the preferences of foreign aid donors. Although similar problems exist elsewhere, in the occupied Palestinian territory they are exacerbated and perpetuated under conditions of military occupation. Developmental approaches integrated with responses to emergencies should be advanced to create a more effective, efficient, and equitable health system, but this process would be difficult under military occupation.

Building social capital in post-conflict communities: Evidence from Nicaragua

Studies of social capital have focused on the static relationship between social capital and health, governance and economic conditions. This study is a first attempt to evaluate interventions designed to improve the levels of social capital in post-conflict communities in Nicaragua and to relate those increases to health and governance issues. The two-year study involved a baseline household survey of approximately 200 households in three communities in Nicaragua, the implementation of systematic interventions designed to increase social capital in two of the locales (with one control group), and a second household survey administered two years after the baseline survey. We found that systematic interventions promoting management and leadership development were effective in improving some aspects of social capital, in particular the cognitive attitudes of trust in the communities. Interventions were also linked to higher levels of civic participation in governance processes. As in other empirical studies, we also found that higher levels of social capital were significantly associated with some positive health behaviors. The behavioral/structural components of social capital (including participation in groups and social networks) were associated with more desirable individual health behaviors such as the use of modern medicine to treat childrens respiratory illnesses. Attitudinal components of social capital were positively linked to community health behaviors such as working on community sanitation campaigns. The findings presented here should be of interest to policy makers interested in health policy and social capital, as well as those working in conflict-ridden communities in the developing world.

Design of an impact evaluation using a mixed methods model – an explanatory assessment of the effects of results-based financing mechanisms on maternal healthcare services in Malawi

BackgroundIn this article we present a study design to evaluate the causal impact of providing supply-side performance-based financing incentives in combination with a demand-side cash transfer component on equitable access to and quality of maternal and neonatal healthcare services. This intervention is introduced to selected emergency obstetric care facilities and catchment area populations in four districts in Malawi. We here describe and discuss our study protocol with regard to the research aims, the local implementation context, and our rationale for selecting a mixed methods explanatory design with a quasi-experimental quantitative component.DesignThe quantitative research component consists of a controlled pre- and post-test design with multiple post-test measurements. This allows us to quantitatively measure ‘equitable access to healthcare services’ at the community level and ‘healthcare quality’ at the health facility level. Guided by a theoretical framework of causal relationships, we determined a number of input, process, and output indicators to evaluate both intended and unintended effects of the intervention. Overall causal impact estimates will result from a difference-in-difference analysis comparing selected indicators across intervention and control facilities/catchment populations over time.To further explain heterogeneity of quantitatively observed effects and to understand the experiential dimensions of financial incentives on clients and providers, we designed a qualitative component in line with the overall explanatory mixed methods approach. This component consists of in-depth interviews and focus group discussions with providers, service user, non-users, and policy stakeholders. In this explanatory design comprehensive understanding of expected and unexpected effects of the intervention on both access and quality will emerge through careful triangulation at two levels: across multiple quantitative elements and across quantitative and qualitative elements.DiscussionCombining a traditional quasi-experimental controlled pre- and post-test design with an explanatory mixed methods model permits an additional assessment of organizational and behavioral changes affecting complex processes. Through this impact evaluation approach, our design will not only create robust evidence measures for the outcome of interest, but also generate insights on how and why the investigated interventions produce certain intended and unintended effects and allows for a more in-depth evaluation approach.

Innovation and Change in the Chilean Health System

Chile has had a two-tiered health system since the 1980s, though successive governments have worked to strengthen the public tier. Despite improvements in some health indicators, satisfaction with the system has declined, and the need for reform is widely acknowledged.

Decentralisation, Governance and Health-System Performance: ‘Where You Stand Depends on Where You Sit’

Advocates of local government often argue that when decentralisation is accompanied by adequate mechanisms of accountability, particularly those responsive to local preferences, improved service delivery will result. From the perspective of the health sector, the appropriate degree of decentralisation and the necessary mechanisms of accountability depend upon the achievement of health system goals. Drawing on evidence from six countries (Bolivia, Chile, India, Pakistan, Philippines, Uganda), this article comes to the conclusion that a balance between centralisation of some functions and decentralisation of others, along with improved mechanisms of accountability, is needed to achieve health system objectives.

The political and administrative context of primary health care in the Third World.

Despite increasing knowledge about technical aspects of Primary Health Care (PHC), there has been as yet only limited research into political and administrative influences on the effectiveness of PHC programs. A three-stage model of the policy process is developed as a framework for organizing the relationships between elements of (1) the national political setting and PHC policy formulation; (2) the implementing agency and program administration; and (3) the community setting and service delivery. Drawing upon the literature on PHC and related programs, hypotheses are proposed for each of these stages as a basis for future study and practical application. Possible output indicators are suggested for each stage of the model. Several basic methodological issues must be addressed in the design of empirical research on political-administrative factors, including variable selection, identification of data sources, and choice of analytical approach. It is hoped that this review will encourage more systematic investigation in this area.

Capital social y salud mental en comunidades urbanas de nivel socioeconómico bajo, en Santiago, Chile: Nuevas formas de entender la relación comunidad-salud

BACKGROUND Many studies suggest that social capital, defined as those intangible resources of a society or community (trust, participation and reciprocity), that might facilitate collective action, can be associated with positive health effects. AIM To explore the relationship between social capital an the level of mental health, in urban communities of Santiago, Chile. MATERIAL AND METHODS In a qualitative-quantitative cross-sectional design, two low income neighborhoods in the municipality of Puente Alto were selected. Interviews to key agents and focus groups, as well as surveys (407) to adults from a representative random sample of households, were conducted, measuring social capital, using a locally devised questionnaire and mental health using the General Health Questionnaire (GHQ-12 instrument). A qualitative analysis based on the grounded theory and a quantitative analysis through correlations and simple and logistic regression models were applied. RESULTS The quantitative analysis found an association between female gender, education and having a chronic disease, with low levels of mental health. At the same time, the trust component of social capital might be associated with a better mental health status. Qualitatively, all the components of social capital were identified as important for a better mental health. CONCLUSIONS This study suggests the existence of a positive relationship between social capital and mental health. Developing trust in a community might be a useful tool to work in mental health at the community level.

Health worker densities and immunization coverage in Turkey: a panel data analysis

BackgroundIncreased immunization coverage is an important step towards fulfilling the Millennium Development Goal of reducing childhood mortality. Recent cross-sectional and cross-national research has indicated that physician, nurse and midwife densities may positively influence immunization coverage. However, little is known about relationships between densities of human resources for health (HRH) and vaccination coverage within developing countries and over time. The present study examines HRH densities and coverage of the Expanded Programme on Immunization (EPI) in Turkey during the period 2000 to 2006.MethodsThe study is based on provincial-level data on HRH densities, vaccination coverage and provincial socioeconomic and demographic characteristics published by the Turkish government. Panel data regression methodologies (random and fixed effects models) are used to analyse the data.ResultsThree main findings emerge: (1) combined physician, nurse/midwife and health officer density is significantly associated with vaccination rates – independent of provincial female illiteracy, GDP per capita and land area – although the association was initially positive and turned negative over time; (2) HRH-vaccination rate relationships differ by cadre of health worker, with physician and health officers exhibiting significant relationships that mirror those for aggregate density, while nurse/midwife densities are not consistently significant; (3) HRH densities bear stronger relationships with vaccination coverage among more rural provinces, compared to those with higher population densities.ConclusionWe find evidence of relationships between HRH densities and vaccination rates even at Turkeys relatively elevated levels of each. At the same time, variations in results between different empirical models suggest that this relationship is complex, affected by other factors that occurred during the study period, and warrants further investigation to verify our findings. We hypothesize that the introduction of certain health-sector policies governing terms of HRH employment affected incentives to provide vaccinations and therefore relationships between HRH densities and vaccination rates. National-level changes experienced during the study period – such as a severe financial crisis – may also have affected and/or been associated with the HRH-vaccination rate link. While our findings therefore suggest that the size of a health workforce may be associated with service provision at a relatively elevated level of development, they also indicate that focusing on per capita levels of HRH may be of limited value in understanding performance in service provision. In both Turkey and elsewhere, further investigation is needed to corroborate our results as well as gain deeper understanding into relationships between health worker densities and service provision.
