National health insurance

National health insurance is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand National health insurance rather than just read about it. In short: National health insurance (NHI), sometimes called statutory health insurance (SHI), is a system of health insurance that insures a national population against the costs of health care. It may be administered by the public sector, the private sector, or a combination of both.

Key takeaways

  • National health insurance belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect National health insurance to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of National health insurance from memory before moving on to harder problems.

Reference excerpt

National health insurance (NHI), sometimes called statutory health insurance (SHI), is a system of health insurance that insures a national population against the costs of health care. It may be administered by the public sector, the private sector, or a combination of both. Funding mechanisms vary with the particular program and country. National or statutory health insurance does not equate to government-run or government-financed health care, but is usually established by national legislation. In some countries, such as Australia's Medicare system, the UK's National Health Service and South Korea's National Health Insurance Service, contributions to the system are made via general taxation and therefore are not optional even though use of the health system it finances is. In practice, most people paying for NHI will join it. Where an NHI involves a choice of multiple insurance funds, the rates of contributions may vary and the person has to choose which insurance fund to belong to.

History Germany has the world's oldest national social health insurance system, with origins dating back to Otto von Bismarck's Sickness Insurance Law of 1883.

Great Britain In Britain, the National Insurance Act 1911 included national social health insurance for primary care (not specialist or hospital care), initially for about one-third of the population—employed working class wage earners, but not their dependents. This system of health insurance continued in force until the creation of the National Health Service in 1948 which created a universal service, funded out of general taxation rather than on an insurance basis, and providing health services to all legal residents.

Types of programs

National healthcare insurance programs differ both in how the contributions are collected, and in how the services are provided. In countries such as Canada, payment is made by the government directly from tax revenue and this is known as single-payer health care. The provision of services may be through either publicly or privately owned health care providers. In France, a similar system of compulsory contributions is made, but the collection is administered by non-profit organisations set up for the purpose. An alternative funding approach is where countries implement national health insurance by legislation requiring compulsory contributions to competing insurance funds. These funds (which may be run by public bodies, private for-profit companies, or private non-profit companies), must provide a minimum standard of coverage and are not allowed to discriminate between patients by charging different rates according to age, occupation, or previous health status (pre-existing medical conditions). To protect the interest of both patients and insurance companies, the government establishes an equalization pool to spread risks between the various funds. The government may also contribute to the equalization pool as a form of health care subsidy. This is the model used in the Netherlands. Other countries are largely funded by contributions by employers and employees to sickness funds. With these programs, funds come from neither the government nor direct private payments. This system operates in countries such as Germany and Belgium. These funds are usually non-profit institutions run solely for the benefit of their members. These systems are characterized by a mixture of three sources of funds in varying degrees: private, employer-employee contributions, and national/subnational taxes. In addition to direct medical costs, some national insurance plans also provide compensation for loss of work due to ill-health, or may be part of wider social insurance plans covering things such as pensions, unemployment, occupational retraining, and financial support for students. National schemes have the advantage that the pool or pools of contributors tend to be vast and reflective of the national population. Health care costs tend to be high at the extremes of age and other specific events in life, such as during pregnancy and childbirth. In a national healthcare scheme, these costs are covered by contributions made to the pool over an individual's lifetime (i.e., higher when earning capacity is greatest to meet costs incurred at times when earning capacity is low or non-existent). This differs from the private insurance schemes with contribution rates that vary year by year, according to health risks such as age, family history, previous illnesses, and height/weight ratios. Consequently, some people tend to have to pay more for their health insurance when they are sick or are least able to afford it. These problems do not exist in national health insurance schemes.

Worked examples

Example 1 — a first encounter with National health insurance

Start with the simplest possible case. Write down what National health insurance claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to National health insurance before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about National health insurance ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of National health insurance

In research
National health insurance appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses National health insurance in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
National health insurance is common in secondary-school and first-year university syllabi. It links to neighbouring topics Health economics, Health policy, Social programs, so understanding it makes those chapters shorter.
In everyday life
Look for National health insurance outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
