Summary of "Global Experience of Mid-Level Health Providers for Delivery of Health-Related Millennium Development Goals"

Purpose and Background

This report addresses the global shortage of health workers, which hinders achievement of Millennium Development Goals (MDGs). It presents a systematic review of evidence comparing mid-level health workers (MLHWs)—such as nurses, midwives, and clinical officers—with physicians, and country case studies from Asia, Africa, and Latin America. The analysis explores MLHWs' effectiveness in delivering essential health services, such as maternal and child care, infectious disease treatment, and chronic disease management. Key recommendations target policymakers, researchers, and the Global Health Workforce Alliance for strengthening health systems.

Methodology

• Systematic Review: Included randomized and observational studies comparing outcomes of care by MLHWs with standard physician-led care, focusing on interventions for key MDG-related conditions. Methodological quality was assessed using GRADE criteria, often finding low or very low evidence quality.
• Country Case Studies: Evaluated health system governance, training programs, deployment strategies, and enabling factors in eight countries: El Salvador, Peru, Mozambique, Tanzania, Zambia, Indonesia, Bangladesh, and Pakistan.

Key Findings

• Effectiveness of MLHWs: Evidence shows MLHWs deliver services comparable to physicians in many areas, including maternal health, anti-retroviral therapy, and chronic disease care. For instance:
  • Midwives achieve similar outcomes to physicians in prenatal and postnatal care but with higher patient satisfaction and reduced use of invasive procedures.
  • Nurses provide care as effective as doctors for infections and chronic conditions, with better patient compliance and satisfaction in some cases. However, evidence is of low quality, necessitating cautious interpretation.
• Barriers and Limitations: Country studies highlight issues such as lack of visibility in health policies, incomplete data in human resources information systems, and weak regulatory oversight. Studies often lack detailed training specifics and long-term outcome data.
• Region-Specific Insights: Sub-Saharan Africa shows promise for task-shifting but needs more high-quality research due to severe workforce shortages.

Recommendations

1. Policy Recommendations:

   • Define national and sub-national skills mix for MLHWs, integrating them into workforce strategies with clear roles and responsibilities.
   • Scale up training, licensing, certification, and supportive supervision to ensure quality care and better deployment.
   • Develop retention incentives, particularly in rural areas, and strengthen regulatory frameworks.
   • Enhance health information systems to include MLHW data for better monitoring and decision-making.

2. Research Recommendations:

   • Conduct more experimental studies, especially in developing countries, to generate high-quality evidence on MLHW effectiveness and cost-effectiveness.
   • Focus on under-explored areas like mental health, non-communicable diseases, and program impact on equity.
   • Evaluate system linkages (e.g., supervision and referrals) to understand broader health system effects.

3. Recommendations for GHWA Members:

   • Disseminate findings through policy briefs and workshops to foster global dialogue and country-specific program improvements.
   • Promote collaborations for quasi-experimental evaluations and long-term follow-up meetings.

MLHWs can significantly contribute to health service delivery, but sustained investment in evidence-based policies and research is essential to realize their full potential.
