What Is a Health System?
A health system is … “The combination of resources, organization, financing, and
management that culminate in the delivery of health services to the population” Roemer (1991)
“All the activities whose primary purpose is to promote, restore, or maintain health” WHO (2000)

Oversight
To keep watch over the health sector
30
HOW DOES A GOVERNMENT PROVIDE OVERSIGHT IN THE HEALTH SECTOR?
How Does a Government Provide Oversight in the Health Sector?
31
Traditional Regulation
The instruments by which governments place requirements on enterprises, citizens, and government itself, including laws, orders, and other rules issued by all levels of government and by bodies to which governments have delegated regulatory powers Economic regulation intervenes directly in enterprise and market
decisions such as pricing, competition, market entry, or exit Social regulation protects values such as health, safety, the
environment, and social cohesion Administrative regulation concerns government formalities and
paperwork, so-called “red tape” Regulatory reform aims at improving regulatory quality, be it the
revision of a single regulation; of regulatory institutions; or improved processes for making regulations and managing reform
Deregulation is a subset of regulatory reform and refers to complete or partial elimination of regulation in a sector
Source: OECD. (1997). 32
Oversight Approaches in the Health Sector
Policy-making
Establish and enforce laws and regulations
Public disclosure
Professional self-regulation
Consumer advocates
Independent media
Independent monitors
33
Effective Regulation in the Health Sector
Informal and formal “rules of the game” (incentives) can greatly influence performance
Local institutions beyond government can be effective: consumer’s groups, professional organizations, media
Co-production-regulation may be more effective than government enforcement of rules

Systems Thinking
Section B
Systems and Non-Systems
Systems Parts are connected Changing one part or
connection affects other elements of the system
Parts operate toward a purpose
Non-systems Parts are independent Changing one part does
not necessarily affect other elements
No explicit purpose
2
Systematic Thinking
Methodical, deliberate
“According to a system” (OED)
Requires using a model and/or theoretical basis for analysis or action
3
Systems Thinking
The process of understanding how things influence each other in a system

Systems Thinking: Key Concepts
Parts of a system are interdependent
Actions have multiple-order consequences
Optimizing one part can lead to poor system performance
Organizational structures drive behavior
Mental models influence actions
6
Systems Thinking Means Less Focus on …
Blueprints and roadmaps
Finding the “right” financing or organization
No “magic bullets” to find

Implementation challenge is a systems problem
Systems Thinking Means More Focus on …
Understand initiating conditions (context)
Identify binding constraints in health systems
Look outside health sector—changing behavior is beyond health services
Look for unintended consequences
Use learning processes to guide change
Understand how organizational structure influences behavior
Use data to guide decisions
9
Systems Thinking Focuses on Results
Common to most strategies to improve implementation
Measure the right things, disclose results, and manage according to results

Effecting Change in a Health System
Section C
Values: Do They Matter?
Working in health systems requires more than technical expertise It depends on values and ethics
Values and ethics drive behavior in any human system
Ethical perspective helps define problems
Ethics help clarify assumptions and implications
2
Influential Ethical Perspectives
Utilitarianism—maximize greatest good for the greatest number Who protects the minority?
Liberalism—individuals have rights to choose for themselves Whose rights prevail when they conflict?
Communitarianism—societies raise members with good character to create the good society Who decides what is the good society?
3
The “Control Knobs” of Public Intervention in Health Systems
1. Oversight—how you regulate and use information to change behavior of key actors
2. Organization—who delivers services and manages health systems inputs and how they are delivered
3. Financing—how to raise money, pool funds, allocate and pay for health care With effective, technically sound services and behaviors
4
Strategies to Improve Implementation in a Health System
5
Strategy type Examples
Public oversight
Policy reviews; regulations; contracting; empowering community oversight, supporting consumer organizations
Organizational change: provider based
Quality improvement programs; training; human resource management; logistics systems; decentralization of public services
Organizational change: community based
Community development programs; demand creation
Health financing Provider payment system change; subsidies; health insurance

Health Service Implementation: Common Findings
Implementation faults are very common
Many different types of strategies can succeed but are not replicable in much detail
Strategies produce many unintended consequences, not predictable in detail
Policy makers define strategies but often have limited influence on how they are implemented

How Strategies Are Implemented Matters

* P-value < 0.05; ** P-value < 0.01
Successful Implementation Factors
Identifying and minimizing systemic constraints
Stakeholder involvement and consultation
Mobilization of adequate resources
The initial and continuous adaptation of the strategy to the local context is associated with more complete strategy implementation, and adaptation is easier in small-scale interventions
Strategies to strengthen disease-specific programs that are effective in one area can be successfully scaled up nationally
Multiple component strategies are more effective than single strategies, but risk of failure is greater
9
What Are the Uses of Health Systems Models?
Identify policy choices and select options
Describe a system (e.g., at national level)
How to strengthen or “reform” a health system
Understand causation of changes in a health system
Plan, monitor, evaluate strategies for implementation and scaling up
Develop theories about health issues
10
Summary
Improving health systems involves its own set of skills and knowledge base, including the ability to … Understand health systems—actors, connections, principles,
purpose Know where and how to intervene Use systems thinking
