A systematic review of the evidence on integration of targeted health interventions into health systems

A longstanding debate on health systems organization relates to benefits of integrating health programmes that emphasize specific interventions into mainstream health systems to increase access and improve health outcomes. This debate has long been characterized by polarization of views and ideologies, with protagonists for and against integration arguing the relative merits of each approach. However, all too frequently these arguments have not been based on hard evidence. The presence of both integrated and non-integrated programmes in many countries suggests there may be benefits to either approach, but the relative merits of integration in various contexts and for different interventions have not been systematically analysed and documented. In this paper we present findings of a systematic review that explores a broad range of evidence on: (i) the extent and nature of the integration of targeted health programmes that emphasize specific interventions into critical health systems functions, (ii) how the integration or non-integration of health programmes into critical health systems functions in different contexts has influenced programme success, (iii) how contextual factors have affected the extent to which these programmes were integrated into critical health systems functions. Our analysis shows few instances where there is full integration of a health intervention or where an intervention is completely non-integrated. Instead, there exists a highly heterogeneous picture both for the nature and also for the extent of integration. Health systems combine both non-integrated and integrated interventions, but the balance of these interventions varies considerably.

Navigating the health system: diabetes care in Georgia

BACKGROUND Effective delivery of diabetes care requires integration across specialist teams delivering recognized interventions, a reliable pharmaceutical supply, and promoting self-management. Drawing on a framework incorporating physical, human, intellectual and social resources, the paper examines how these challenges are managed in diabetes care in Georgia. METHODS The rapid appraisal study triangulated data from interviews with users, providers and key informants from various institutions in four regions of Georgia; data on clinical and social outcomes from diabetes; legislative and policy documents. RESULTS Diabetes-related mortality in Georgia is among the worst in Europe and Central Asia, in a context of conflict, economic collapse and weak institutions. Essential inputs for diabetes care are in place (free insulin, training for primary care physicians, financed package of care), but constraints within the system hamper the delivery of accessible and affordable care. There are no evidence-based guidelines on diabetes management, formal support and quality assurance. The scope of work of primary care practitioners is limited and they rarely diagnose and manage diabetes, which instead takes place within the vertical system. Access to insulin is problematic in rural areas. Obtaining syringes, supplies and hypoglycemic drugs and self-monitoring equipment remains difficult everywhere. Prevention and effective management of complications is limited, increasing adverse outcomes. Diagnosis and treatment of diabetes complications involve hospital admission and unaffordable out-of-pocket payments. The complexity of pathways to key stages of care obstructs continuous care. There are poor linkages between primary and secondary care and ineffective patient follow-up or monitoring of outcomes. There is little effort to promote self-care, adherence to drug regimens and appropriate lifestyle, or to empower patients. CONCLUSIONS Improving diabetes outcomes will involve simplifying pathways to care and drugs, reassessing staff roles and insulin distribution systems. This would require better co-ordination of the inputs into the system and development of an integrated and patient-centred model.

Economic benefit of tuberculosis control

Tuberculosis is the most important infectious cause of adult deaths after HIV/AIDS in low- and middle-income countries. This paper evaluates the economic benefits of extending the World Health Organizations DOTS Strategy (a multi-component approach that includes directly observed treatment, short course chemotherapy and several other components) as proposed in the Global Plan to Stop TB, 2006-2015. The authors use a model-based approach that combines epidemiological projections of averted mortality and economic benefits measured using value of statistical life for the Sub-Saharan Africa region and the 22 high-burden, tuberculosis-endemic countries in the world. The analysis finds that the economic benefits between 2006 and 2015 of sustaining DOTS at current levels relative to having no DOTS coverage are significantly greater than the costs in the 22 high-burden, tuberculosis-endemic countries and the Africa region. The marginal benefits of implementing the Global Plan to Stop TB relative to a no-DOTS scenario exceed the marginal costs by a factor of 15 in the 22 high-burden endemic countries, a factor of 9 (95% CI, 8-9) in the Africa region, and a factor of 9 (95% CI, 9-10) in the nine high-burden African countries. Uncertainty analysis shows that benefit-cost ratios of the Global Plan strategy relative to sustained DOTS were unambiguously greater than one in all nine high-burden countries in Africa and in Afghanistan, Pakistan, and Russia. Although HIV curtails the effect of the tuberculosis programs by lowering the life expectancy of those receiving treatment, the benefits of the Global Plan are greatest in African countries with high levels of HIV.

Essential obstetric care: Assessment and determinants of quality

This paper reports on a study to develop and to apply methods for measuring the quality of essential obstetric care (EOC) in health centers. Based on a Nigerian guideline and an international guideline, and in consultation with local experts in primary care obstetrics, norms were established for equipment, personnel, supplies and the process of EOC, focusing on critical tasks. A combination of assessment methods was used, including observation of tasks performed during intrapartum care; use of data from records of care kept by midwives during the period of observation; use of data from records kept by midwives in the calendar year preceding the period of observation; exit interviews with clients; and inventories of equipment and supplies. Twelve health centers in three Local Government Areas (LGAs) and 360 clients in labor were included in the study. Quality of care was measured quantitatively as a score, calculated for each task and for each delivery in the health center. The results show that the methods developed are useful for: identifying quality score differences among health centers, and the effects of methods of assessment on quality scores; identifying aspects of EOC requiring improvements within each health center; and identifying factors influencing the quality of care, as a basis for effective quality improvement efforts. Regression models show that the most consistent and important predictor of quality scores is the use of printed forms (i.e. routine records of labor) during intrapartum care. Printed forms served as job aids, providing prompts that reminded midwives to perform specific tasks.

Global investments in TB control: economic benefits.

The Global Plan to Stop TB calls for significant financial resources to meet the Millennium Development Goals for tuberculosis. However, it is unclear whether the economic benefits of TB control exceed the costs. Using an epidemiological model, we find that the economic benefits of the Global Plan relative to sustained DOTS (a commonly used treatment method) were unambiguously greater than the incremental costs in all nine high-burden countries in Africa and in Afghanistan, Pakistan, and Russia. Benefit-cost ratios of sustaining DOTS at current levels relative to having no DOTS exceeded 1 in all twenty-two high-burden, TB-endemic countries and sub-Saharan Africa.

Integration of priority population, health and nutrition interventions into health systems: systematic review.

BackgroundObjective of the study was to assess the effects of strategies to integrate targeted priority population, health and nutrition interventions into health systems on patient health outcomes and health system effectiveness and thus to compare integrated and non-integrated health programmes.MethodsSystematic review using Cochrane methodology of analysing randomised trials, controlled before-and-after and interrupted time series studies. We defined specific strategies to search PubMed, CENTRAL and the Cochrane Effective Practice and Organisation of Care Group register, considered studies published from January 1998 until September 2008, and tracked references and citations. Two reviewers independently agreed on eligibility, with an additional arbiter as needed, and extracted information on outcomes: primary (improved health, financial protection, and user satisfaction) and secondary (improved population coverage, access to health services, efficiency, and quality) using standardised, pre-piloted forms. Two reviewers in the final stage of selection jointly assessed quality of all selected studies using the GRADE criteria.ResultsOf 8,274 citations identified 12 studies met inclusion criteria. Four studies compared the benefits of Integrated Management of Childhood Illnesses in Tanzania and Bangladesh, showing improved care management and higher utilisation of health facilities at no additional cost. Eight studies focused on integrated delivery of mental health and substance abuse services in the United Kingdom and United States of America. Integrated service delivery resulted in better clinical outcomes and greater reduction of substance abuse in specific sub-groups of patients, with no significant difference found overall. Quality of care, patient satisfaction, and treatment engagement were higher in integrated delivery models.ConclusionsTargeted priority population health interventions we identified led to improved health outcomes, quality of care, patient satisfaction and access to care. Limited evidence with inconsistent findings across varied interventions in different settings means no general conclusions can be drawn on the benefits or disadvantages of integrated service delivery.

The quest for universal access to effective malaria treatment: how can the AMFm contribute?

Access to quality assured artemisinin-based combination therapy (ACT) has remained very low in most malaria endemic countries. A number of reasons, including unaffordable prices, have contributed to the low accessibility to these life-saving medicines. The Affordable Medicines Facility-Malaria (AMFm) is a mechanism to increase access to quality assured ACT. The AMFm will use price signals and a combination of public and private sector channels to achieve multiple public health objectives: replacing older and increasingly ineffective anti-malarial medicines, such as chloroquine and sulphadoxine-pyrimethamine with ACT, displacing oral artemisinin monotherapies from the market, and prolonging the lifespan of ACT by reducing the likelihood of resistance to artemisinin.Access to medicines frameworks paint a broad picture of dimensions of access to medicines and juxtapose components that enhance or hinder access to medicines. Access requires various activities--funding, institutions, interventions, and thinking--from public and private actors at global, national, and local levels. This paper examines, within access to medicines frameworks, the role of the AMFm across and within each dimension and discusses how the AMFm can help to solve access bottlenecks.

Concepts and methods for assessing the quality of essential obstetric care.

Approaches to reducing maternal mortality and morbidity have attracted much attention in the last decade. It is recognized that availability and use of essential obstetric care (EOC) of sound quality by women in labor would reduce the burden of illness and death resulting from pregnancy. However, the literature on methods for defining, assessing and improving the quality of EOC at the point of service delivery in developing countries is quite weak. Drawing upon fundamental concepts of quality assurance, statistics, clinical practices and health service management, this article presents unifying concepts and methods for defining, assessing and improving the quality of EOC in developing country settings. It argues that any intervention that would improve the quality of EOC must act through at least one of three mechanisms: improve the clinical management of uncomplicated labor; improve the detection of complications of labor; or, improve the clinical management of complications of labor. The text presents the basis for using quantitative and qualitative methods to assess the quality of EOC. It concludes that any method to assess the quality of EOC, as a basis for improvement at the health center level, must satisfy the following seven criteria: (i) be derived from scientifically sound and locally defined guidelines for what constitutes care of good quality; (ii) enable objectively verifiable measurements of the performance of critical tasks; (iii) be sufficiently discriminating to detect variations in quality among health centers, thereby enabling managers to focus on improving care in those health centers providing care of lower quality; (iv) facilitate production of visual aids within each health center, thereby enabling midwives, doctors and their supervisors to use information for improving their work on a daily basis; (v) include qualitative assessments to facilitate interpretation of quantitative information; (vi) be reasonably simple to use without unsustainable foreign technical assistance; and, (vii) be affordable within the limited resources of public health facilities and District Health Management Teams.

Universal health coverage and intersectoral action for health: key messages from Disease Control Priorities, 3rd edition

The World Bank is publishing nine volumes of Disease Control Priorities, 3rd edition (DCP3) between 2015 and 2018. Volume 9, Improving Health and Reducing Poverty, summarises the main messages from all the volumes and contains cross-cutting analyses. This Review draws on all nine volumes to convey conclusions. The analysis in DCP3 is built around 21 essential packages that were developed in the nine volumes. Each essential package addresses the concerns of a major professional community (eg, child health or surgery) and contains a mix of intersectoral policies and health-sector interventions. 71 intersectoral prevention policies were identified in total, 29 of which are priorities for early introduction. Interventions within the health sector were grouped onto five platforms (population based, community level, health centre, first-level hospital, and referral hospital). DCP3 defines a model concept of essential universal health coverage (EUHC) with 218 interventions that provides a starting point for country-specific analysis of priorities. Assuming steady-state implementation by 2030, EUHC in lower-middle-income countries would reduce premature deaths by an estimated 4·2 million per year. Estimated total costs prove substantial: about 9·1% of (current) gross national income (GNI) in low-income countries and 5·2% of GNI in lower-middle-income countries. Financing provision of continuing intervention against chronic conditions accounts for about half of estimated incremental costs. For lower-middle-income countries, the mortality reduction from implementing the EUHC can only reach about half the mortality reduction in non-communicable diseases called for by the Sustainable Development Goals. Full achievement will require increased investment or sustained intersectoral action, and actions by finance ministries to tax smoking and polluting emissions and to reduce or eliminate (often large) subsidies on fossil fuels appear of central importance. DCP3 is intended to be a model starting point for analyses at the country level, but country-specific cost structures, epidemiological needs, and national priorities will generally lead to definitions of EUHC that differ from country to country and from the model in this Review. DCP3 is particularly relevant as achievement of EUHC relies increasingly on greater domestic finance, with global developmental assistance in health focusing more on global public goods. In addition to assessing effects on mortality, DCP3 looked at outcomes of EUHC not encompassed by the disability-adjusted life-year metric and related cost-effectiveness analyses. The other objectives included financial protection (potentially better provided upstream by keeping people out of the hospital rather than downstream by paying their hospital bills for them), stillbirths averted, palliative care, contraception, and child physical and intellectual growth. The first 1000 days after conception are highly important for child development, but the next 7000 days are likewise important and often neglected.
