Health system models, explained

The four models side by side

Two distinctions run through the table. The first is who pays versus who delivers: a system can be publicly funded and privately delivered, or privately funded and publicly delivered, and most combinations exist somewhere. The second is coverage: the first three models aim at universal coverage, while out-of-pocket systems, by definition, cover only those who can pay.

Beveridge: the national health service

In the Beveridge model, named after the British economist William Beveridge, the government funds healthcare from general taxation and mostly delivers it through government-run services. The United Kingdom’s NHS is the classic example: public coverage for all, funded from taxation, with GPs as the first point of contact. Spain runs a similar model. Because funding comes from taxes, the cost of care is spread across the whole population according to what people earn, not according to how sick they are — and care is free at the point of use.

Bismarck: sickness funds

In the Bismarck model, named after the German chancellor Otto von Bismarck, workers and employers pay contributions into non-profit sickness funds, and those funds pay private providers. Germany is the classic example, and France runs a similar system. The funds are heavily regulated — they must cover a defined package, and they may not turn people away — but they are not government departments. Delivery stays mostly private: hospitals and clinics are run by non-profit or private organisations, and patients generally have free choice of provider.

National health insurance: single-payer

In the national health insurance model, one public insurer pays for care while delivery stays mostly private. Canada is the classic example: each province and territory runs a single public plan that pays private doctors and hospitals. Taiwan runs a single national insurer the same way. This is the model the single-payer guide explains in full — and the key distinction is that single-payer is about financing, not delivery. The government writes the cheques; it does not necessarily run the hospitals.

Out-of-pocket: paying directly

Where no universal system exists, people pay directly for care — the out-of-pocket model. It is the default in much of the world, and the only model that does not pool risk at all: a household’s bill depends entirely on what illness strikes it, and the poorest pay the largest share of their income. Even in countries with universal systems, some services sit outside the covered package and are paid out of pocket — dental care and prescription drugs are common examples.

Social health insurance vs private health insurance

The Bismarck and national-health-insurance models both use insurance, but they are social insurance: membership is compulsory, contributions are based on income rather than risk, and the insurer may not refuse anyone. Private health insurance is different on all three counts: it is usually voluntary, priced by risk, and can refuse applicants or exclude conditions. Confusing the two is the most common misunderstanding in this area — “insurance-based” does not mean “private”.

Mirror, Mirror: how systems are compared

The Commonwealth Fund’s Mirror, Mirror 2024 compares 10 high-income countries on 70 measures across 5 domains: access to care, care process, administrative efficiency, equity and health outcomes. The method matters more than any single result: the report measures the same things the same way in each country, so differences reflect the systems rather than the statistics. This article reports the method only and gives no ranking verdict — the Fund’s findings are the Fund’s, and a reader who wants them should read the report itself. One method note is worth recording: Norway took part in earlier editions but exited the Fund’s survey in 2022, so it does not appear in the 2024 comparison.

Most systems mix the models

No country runs one model purely. The United Kingdom’s NHS buys some services from private providers. Germany’s sickness funds sit alongside a tax-funded safety net. Japan mixes Bismarck-style social insurance with a large public subsidy. The United States mixes employer insurance, public programmes and out-of-pocket payment in a single system. The four models are useful because they name the ingredients — not because any country is made of only one.

Worked example: Canada vs the UK

Both countries are publicly funded mainly from general taxation — and the comparison shows how much else differs.

Canada. Health Canada describes a predominantly publicly financed, privately delivered system: an interlocking set of ten provincial and three territorial health insurance plans, providing universal, comprehensive coverage for medically necessary hospital and physician services. The Canada Health Act (1984) sets five principles the provincial plans must meet — public administration, comprehensiveness, universality, portability and accessibility. Healthcare is financed primarily through taxation, in the form of provincial and federal personal and corporate income taxes. Canadians do not pay directly for insured hospital and physician services, and there are no deductibles, co-payments or dollar limits on coverage for insured services. Most doctors are private practitioners, usually paid on a fee-for-service basis by the provincial plan.

The UK. The NHS is a national service funded through national taxation, and services are free of charge except in limited circumstances sanctioned by Parliament. Access is based on clinical need, not on an individual’s ability to pay (NHS Constitution for England). Unlike Canada, delivery is mostly public: hospitals and community services are largely government-run, with GPs as the first point of contact.

Same funding source, different delivery — which is why “who pays” and “who delivers” must be asked separately.

How healthcare systems compare

Comparing systems is a method question, not a single figure. Three frames are used together:

1. Financing model — which of the four models above a system resembles, and how far it mixes them.
2. WHO’s UHC indicators — the service coverage index (SDG 3.8.1) and financial hardship from health spending (SDG 3.8.2). The service coverage index rose from 54 to 71 between 2000 and 2023, while about 4.6 billion people were still not fully covered in 2023 (WHO UHC fact sheet, published 5 December 2025).
3. Outcomes — life expectancy and healthy life expectancy, and other population measures. The WHO Global Health Observatory is the data source for the comparison.

No single frame settles a comparison: a system can score well on coverage and poorly on financial protection, or the other way round.

Frequently asked questions

Is single-payer the same as the Beveridge model?

No. Beveridge means the government funds care from taxes and mostly delivers it itself. Single-payer means one public insurer pays, while delivery stays mostly private — as in Canada.

Which model is best?

This article does not rank models or countries. Each model organises the same three questions — who pays, who delivers, who is covered — differently, with different trade-offs.

Does any country use one model purely?

No. Most real systems mix the models: a Beveridge country may have private providers, and a Bismarck country may have a tax-funded safety net.
