Healthcare models refer to the various systems and frameworks that countries use to deliver medical services to their populations. These models can be categorized into several types, including the Beveridge Model, where healthcare is provided and financed by the government, and the Bismarck Model, which relies on employer and employee contributions to fund health insurance. Other models include the National Health Insurance Model, which combines elements of both public and private funding, and the Out-of-Pocket Model, where individuals pay for their healthcare services directly. Each model has its own advantages and challenges, influencing access, quality, and cost of care.
