Health system performance assessment (HSPA) is the process of monitoring, evaluating and communicating to what extent various aspects of a health system meet key objectives. The central purpose of HSPA is to assess whether progress is being made towards desired goals and whether appropriate activities are undertaken to promote achievement of those goals.

Before elaborating on the concept of health system performance assessment (HSPA) further, it is helpful to first shed some light on the different concepts and terminology related to this topic. The following table illustrates the differences between a ‘healthcare system’ and a ‘health system.’

Table 1. The difference between a healthcare system and a health system, and between healthcare system performance and health system performance

TerminologyExplanation
Healthcare systemCombined functioning of public health and personal healthcare services that are under the direct control of identifiable agents, especially ministries of health.
Healthcare system performanceThe efficiency and equitability of the professional public health and personal healthcare services within a system, including a cost-benefit analysis.
Health systemAll activities and structures that determine or influence health in its broadest sense within a given society. This also includes social, environmental and economic determinants of health.
Health system performanceA broader concept that also acknowledges the broad range of determinants of population health that are not directly related to healthcare service delivery. It embraces the notion that the health status of a population is only partly influenced by the quality of the available healthcare services, and that there are many other social, cultural, political, economic, environmental, educational and demographic factors influencing population health.

There are three distinct strengths to a health system performance assessment compared to a healthcare system performance assessment, namely:

  1. A health system performance assessment embodies a holistic approach. The whole system is incorporated, and the assessment surpasses the narrow scope of just the healthcare system.
  2. Involvement of all stakeholders is possible. It gives the various agents a sense of ownership and responsibility, and helps them to make informed decisions.
  3. There is a strong emphasis on the overarching objectives of health systems.

 

Five key characteristics of HSPA

There are 5 key characteristics for adequately applying the concept of health system performance assessment (HSPA). HSPA should be:

  • Regular: Assessing the performance of a health system is a continuous and iterative process.
  • Systematic: The approach should be structured and consistent.
  • Transparent: The assessment has to be clear, unambiguous and understandable for others.
  • Comprehensive: The whole system should be covered. Furthermore, we have to be aware that the performance of a system does not simply equal the sum of the performance of its various components.
  • Analytical: Complementary sources of information should be consulted to obtain a comprehensive and well-founded overview of the health system’s performance. Quantitative indicators should be supported by qualitative insights, just like performance indicators should be supported by a policy analysis. HSPA is in essence a comparative evaluation, and the reference points for comparison have to be chosen wisely. Some relevant reference points for comparison could be:
    • Developments over time
    • Local, regional, national or international differences
    • Differences between population groups (e.g. based on age, gender, income, SES etc.)
    • Comparisons to certain targets or benchmarks

 

The WHO Health Systems Framework

The WHO states that a health system consists of all organizations, people and actions whose primary objective is to promote, restore or maintain health. The WHO has developed a model which is comprised of six building blocks. Collectively, these six building blocks represent the ‘complete’ health system. The building blocks are illustrated in the following figure.

  • Service delivery: This represents the effectiveness, safety and the quality of health interventions. It means that health interventions are available to whoever needs them, regardless of where and when they are needed, with minimum waste of resources.
  • Health workforce: A professional health workforce is responsive, fair and efficient in achieving the best possible health outcomes, making optimal use of the available resources and given circumstances. There should be an adequate number and diversity of competent, productive and responsive medical professionals, distributed fairly amongst society.
  • Health information system: A well-functioning health information system ensures the production, analysis, dissemination and use of reliable and up-to-date information on health determinants, health system performance and health status.
  • Access to Essential Medicines: Essential medical products, vaccines and technologies should be equitably accessible to the population. These medical provisions should be of guaranteed quality, safety, efficacy and cost-effectiveness.
  • Financing: Adequate funding for health should be ensured, to make sure citizens can obtain needed services. Citizens should be protected from disproportionate financial losses when obtaining health services.
  • Stewardship/Governance: Also called leadership. It involves establishing strategic policy frameworks in which effective oversight, coalition-building, adequate regulations and incentives, and accountability issues are all properly implemented and addressed.

 

Which dimensions and indicators to choose for HSPA?

An indicator is appropriate for inclusion in a HSPA if 5 critera are met, as illustrated in table 2 below.

Table 2. The 5 criteria that make an indicator suitable for inclusion in a HSPA (source: Veilard et al. 2010)

CriteriaDescription
ImportanceThe indicator reflects critical aspects of health system functioning
RelevanceThe indicator provides information that is useful for monitoring and measuring health system performance for an extended time period
FeasibilityThe required data are readily available or can be obtained with reasonable efforts
ReliabilityThe indicator produces consistent results
ValidityThe indicator is an accurate reflection of the dimension it is supposed to represent

To conclude, table 3 provides an overview of potentially relevant dimensions, including several exemplary indicators per dimension.
