HEALTH SYSTEMS

1
HEALTH SYSTEMS

• Conceptual frameworks

2
Health systems

• Combination of resources, organization,
  financing, and management that culminates in the
  delivery of health services to the population
•     Roemer MI. National health systems of the
  world, volume 1. New York, Oxford University
  Press, 1991
• All activities whose primary purpose is to
  promote, restore and maintain health
• World Health Report 2000

3
Health systems

• All components are interacting with each other in
  a synergy and coherence
• HS components are interacting with the political,
  social, economic environment
• HS are dynamic and evolve over time

4
Health systems

• HS boundaries
• in relation to health actions activities with
  indirect impact are to be excluded (investments
  on water supply and sanitation, food subsidies,
  supplementary school health meals, etc)

5
HS goals

• To improve health and to reduce health
  inequalities ( average distribution)
• To secure fairness of financial contribution (
  equity concerns)
• To be responsive to users needs

6
HS functions building blocks

• Governance
• Financing
• Human resources
• Service delivery
• Health technology support
• Health information support

7
Health systems

• Health system comprises three highly
  inter-dependent elements
• Ecosystem - socio-cultural, demographic, economic
  and political surroundings
• Health Care Delivery System based on health
  problems and needs, health inputs, distribution,
  output, utilization and outcomes
• Community Involvement organization, awareness,
  contribution and utilization
• A. A. Kielmann

Contribution of health systems

• Health status has improved before HS development
  world wide role of social economic
  determinants of health
• Regression analysis of 6 determinants has shown
  high correlation
• Difficult to disentangle HS contribution
• Comparative analysis
• countries with similar economic status
  similar social determinants of health

Contribution of health systems

• Studies have shown that HS do matter
• - improved equity
• - increased efficiency
• - improved responsiveness population
• satisfaction
• Health outcomes are related to the HS development
  need to invest in HSD
• Importance of HS performance assessment

17
HSP Assessment

• Frameworks
• - HFA measurement of indicators ME
• - social determinants of health MDG( literacy,
  
• income, access to water sanitation, etc..)
• - Input indicators ( HRH, facilities, funds)
• - coverage by services
• - outcome indicators LE, morbidity,
• mortality, quality of life

18
HSP Assessment

• Frameworks
• WHR 2000
• Social determinants are not assessed
• Intermediary goals are not considered
  coverage indicators
• Only outcome indicators
• - LE ( HALE)
• - Fairness of FC index
• - Level and distribution of responsiveness

19
HSP Assessment

• Measurement of HSP
• Sources of data routine information systems
  population-based surveys
• Household expenditures utilization surveys
  are important ( NHA, FFC, catastrophic spending
  on health)
• National BOD analysis ( HALE)

20
Conclusions

• HS are important deserve to be strengthened
• HS do interact with surrounding political,
  economic, cultural environments
• HS functions need to be mapped
• - assess strengths weaknesses
• - improve implementation
• HS goals should be monitored evaluated

21
Conclusions

• Need to strengthen information support to HS
  routine population-based surveys
• Need to invest in capacity building
• - development of analytical tools NHA, BOD,
  CEA
• - health system research
• - policy analysis policy dialogue
