    Delivery arrangements for health systems in low-income countries : an overview of systematic reviews
    (John Wiley & Sons, Ltd. on behalf of The Cochrane Collaboration, 2017) Ciapponi, Agustin; Lewin, Simon; Herrera, Cristian A.; Opiyo, Newton; Pantoja, Tomas; Paulsen, Elizabeth; Rada, Gabriel; Wiysonge, Charles S.; Bastias, Gabriel; Dudley, Lilian; Flottorp, Signe; Gagnon, Marie-Pierre; Marti, Sebastian Garcia; Glenton, Claire; Okwundu, Charles I.; Penaloza, Blanca; Suleman, Fatima; Oxman, Andrew D.
    Background: Delivery arrangements include changes in who receives care and when, who provides care, the working conditions of those who provide care, coordination of care amongst different providers, where care is provided, the use of information and communication technology to deliver care, and quality and safety systems. How services are delivered can have impacts on the effectiveness, efficiency and equity of health systems. This broad overview of the findings of systematic reviews can help policymakers and other stakeholders identify strategies for addressing problems and improve the delivery of services. Objectives: To provide an overview of the available evidence from up‐to‐date systematic reviews about the effects of delivery arrangements for health systems in low‐income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on delivery arrangements and informing refinements of the framework for delivery arrangements outlined in the review. Methods: We searched Health Systems Evidence in November 2010 and PDQ‐Evidence up to 17 December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well‐conducted systematic reviews of studies that assessed the effects of delivery arrangements on patient outcomes (health and health behaviours), the quality or utilisation of healthcare services, resource use, healthcare provider outcomes (such as sick leave), or social outcomes (such as poverty or employment) and that were published after April 2005. We excluded reviews with limitations important enough to compromise the reliability of the findings. Two overview authors independently screened reviews, extracted data, and assessed the certainty of evidence using GRADE. We prepared SUPPORT Summaries for eligible reviews, including key messages, 'Summary of findings' tables (using GRADE to assess the certainty of the evidence), and assessments of the relevance of findings to low‐income countries. Main results: We identified 7272 systematic reviews and included 51 of them in this overview. We judged 6 of the 51 reviews to have important methodological limitations and the other 45 to have only minor limitations. We grouped delivery arrangements into eight categories. Some reviews provided more than one comparison and were in more than one category. Across these categories, the following intervention were effective; that is, they have desirable effects on at least one outcome with moderate‐ or high‐certainty evidence and no moderate‐ or high‐certainty evidence of undesirable effects.

    Governance arrangements for health systems in low-income countries : an overview of systematic reviews
    (John Wiley & Sons, Ltd. on behalf of The Cochrane Collaboration, 2017) Herrera, Cristian A.; Lewin, Simon; Paulsen, Elizabeth; Ciapponi, Agustin; Opiyo, Newton; Pantoja, Tomas; Rada, Gabriel; Wiysonge, Charles S.; Bastias, Gabriel; Marti, Sebastian Garcia; Okwundu, Charles I.; Penaloza, Blanca; Oxman, Andrew D.
    Background: Governance arrangements include changes in rules or processes that determine authority and accountability for health policies, organisations, commercial products and health professionals, as well as the involvement of stakeholders in decision‐making. Changes in governance arrangements can affect health and related goals in numerous ways, generally through changes in authority, accountability, openness, participation and coherence. A broad overview of the findings of systematic reviews can help policymakers, their technical support staff and other stakeholders to identify strategies for addressing problems and improving the governance of their health systems. Objectives: To provide an overview of the available evidence from up‐to‐date systematic reviews about the effects of governance arrangements for health systems in low‐income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on governance arrangements and informing refinements of the framework for governance arrangements outlined in the overview. Methods: We searched Health Systems Evidence in November 2010 and PDQ Evidence up to 17 December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well‐conducted systematic reviews of studies that assessed the effects of governance arrangements on patient outcomes (health and health behaviours), the quality or utilisation of healthcare services, resource use (health expenditures, healthcare provider costs, out‐of‐pocket payments, cost‐effectiveness), healthcare provider outcomes (such as sick leave), or social outcomes (such as poverty, employment) and that were published after April 2005. We excluded reviews with limitations that were important enough to compromise the reliability of the findings of the review. Two overview authors independently screened reviews, extracted data and assessed the certainty of evidence using GRADE. We prepared SUPPORT Summaries for eligible reviews, including key messages, 'Summary of findings' tables (using GRADE to assess the certainty of the evidence) and assessments of the relevance of findings to low‐income countries. Main results: We identified 7272 systematic reviews and included 21 of them in this overview (19 primary reviews and 2 supplementary reviews). We focus here on the results of the 19 primary reviews, one of which had important methodological limitations. The other 18 were reliable (with only minor limitations). We grouped the governance arrangements addressed in the reviews into five categories: authority and accountability for health policies (three reviews); authority and accountability for organisations (two reviews); authority and accountability for commercial products (three reviews); authority and accountability for health professionals (seven reviews); and stakeholder involvement (four reviews). Overall, we found desirable effects for the following interventions on at least one outcome, with moderate‐ or high‐certainty evidence and no moderate‐ or high‐certainty evidence of undesirable effects.
