Assess whether people can get needed care, whether that care is timely, safe and effective, whether households are protected from unaffordable costs, and how results differ across population groups. Then interpret those measures in light of each country’s social, economic, demographic and environmental conditions.
How do you compare healthcare systems?
Start by defining what you want to compare: the countries or regions, years, population, and services. Then follow a chain from resources and policy to services and public-health interventions to outcomes. Spending and facility counts describe parts of the system’s resources or capacity; on their own, they do not show whether people receive good care or are financially protected.
The OECD’s 2024 renewed health system performance assessment framework organizes assessment around this chain. Its cross-cutting concerns include efficiency, equity, sustainability and resilience. WHO’s 2022 framework similarly connects system functions—including governance, financing, resource generation and service delivery—with goals such as health improvement, people-centredness, financial protection, efficiency and equity. These are ways to organize evidence, not universal scorecards.
Set a comparison that can be answered
Specify the time period and the level of comparison. A national measure for a whole population is not directly interchangeable with a hospital-level measure or a result for one service. Decide whether the central question concerns access, quality, affordability, outcomes, efficiency or the system’s ability to withstand shocks.

Keep inputs, services and outcomes distinct
Inputs include funding, workforce and infrastructure. Services and interventions describe what the system delivers. Outcomes show what happens to people. Keeping these categories separate helps avoid treating a larger budget or more facilities as proof of better performance.
Which indicators show whether people can get care?
Access and coverage ask whether people can obtain the services they need, wherever they live and regardless of financial or social circumstances. Consider availability and timeliness as well as whether a service is nominally covered. Useful measures include geographic access, reported barriers related to distance or cost, service availability, waiting times for elective surgery and universal health coverage (UHC) service coverage.
Coverage alone does not establish that care is reachable in practice. Compare reported barriers and waiting times alongside coverage, using definitions and years that are as consistent as possible. WHO’s primary health care (PHC) measurement framework includes indicators spanning health-system capacity, service delivery and health outcomes.
How can you compare quality and safety?
Quality concerns whether care is effective, evidence-based and safe—not simply whether services were provided. Look for indicators that reflect clinical practice and avoidable harm, such as diagnostic accuracy, adherence to clinical standards, complications, readmissions and hospital-acquired infections. For selected conditions, 30-day case fatality can offer another quality signal.
No single measure captures quality across all services. Interpret each indicator in its clinical and population context, and avoid treating a result for one condition as a verdict on the entire system.
How should financial protection be assessed?
A system’s financing is not the same as household protection. Ask whether people incur large or impoverishing health expenses when they seek care. WHO’s PHC framework includes the population share experiencing large or impoverishing household health expenditure as a financial-protection measure.
Rank #3
Read this alongside access measures: low out-of-pocket spending by itself does not show whether people can obtain needed services. The comparison should make clear which costs and households a measure covers and which year it represents.
Which health outcomes belong in the comparison?
Outcomes can show whether population health is improving, but they do not automatically reveal what the health system caused. Socioeconomic conditions, demographics and the environment also shape health and the results a system can achieve. Interpret outcome measures alongside those conditions rather than attributing every difference between countries to healthcare organization.
Examples include healthy life expectancy, avoidable mortality, maternal, neonatal and under-five mortality, and premature mortality from noncommunicable diseases. WHO’s PHC framework includes indicators in these areas. Select outcomes that fit the question and population rather than assembling a broad list without a clear purpose.
Rank #4
Why national averages can mislead
A national average can conceal who is missing out. Compare relevant access, quality and outcome measures across socioeconomic groups and other population characteristics where comparable data are available. Equity concerns how resources are allocated and how access, care quality and outcomes are distributed—not only whether a country’s overall average is high.
Indicators can illuminate more than one dimension. For example, diabetes admissions may be a quality signal, while differences in those admissions across socioeconomic groups can also reveal an equity issue. The OECD framework emphasizes that assessment should examine these connections rather than assume every indicator belongs to only one category.

Efficiency
Efficiency compares resources used with outcomes achieved. Define the population, service and period before making a comparison; otherwise, differences in what is counted can make the comparison misleading. High spending is an input, not evidence by itself that resources are being used efficiently.

People-centred care
Assess whether services reflect people’s needs and preferences. The OECD framework identifies voice, choice, co-production, respectfulness and integration as parts of people-centredness. These considerations add information that expenditure, capacity and clinical outcomes alone may not capture.
Resilience and sustainability
Resilience concerns whether a system can maintain performance under extreme stress. Sustainability looks at whether performance can continue over time, including fiscal and broader environmental considerations. These are system-wide questions; a single facility count or routine-year outcome cannot answer them on its own.
How to build a fair comparison
- Define the scope. Name the countries or regions, years, population, services and performance question.
- Map the evidence chain. Separate resources and policy from services or interventions, then from outcomes.
- Choose multiple indicators for each major goal. A single measure can reflect several system dimensions and cannot stand in for a whole goal.
- Check definitions, years and populations. Confirm that each measure is sufficiently comparable before drawing conclusions; explain any differences in scope.
- Show distribution where possible. Break measures down by relevant socioeconomic and population groups, rather than relying only on national averages.
- Interpret results in context. Consider social, economic, demographic and environmental conditions, and avoid unsupported causal claims.
WHO’s 2022 framework is explicitly a conceptual aid for organizing health-system assessment information, not an operational ranking tool. WHO also lists a renewed global health-system performance assessment framework dated 2026, described as supporting the identification of bottlenecks and policy responses. The existence of that newer publication does not make any one set of measures a universal ranking formula.
What WHO’s indicator counts do—and do not—mean
WHO’s PHC framework page labels its indicator set as 39 Tier 1 indicators and 48 Tier 2 indicators. These are counts of indicators shown in the framework, not scores for countries and not a recommendation to use every indicator in every comparison. Choose measures that fit the question and can be compared on a consistent basis.
