At the broadest systems level, there are several possible national healthcare systems. Hypothetically, there might be a free-market approach to healthcare, in which there would be little or no government regulation. No country has implemented such a system, and even if it were possible, it is not clear that burnout risk to healthcare providers would be reduced. More familiarly, the socialized medicine approach is implemented in many parts of the world. Such a system, in which the government provides healthcare, free to the patient and paid for by taxes, has many well-known pros and cons. The hybrid system, as seen in the United States, combines elements of the free-market and the socialized medicine approaches, and also has its pros and cons. There is growing interest in so-called universal healthcare, which tilts the hybrid system a bit more in the direction of socialized medicine. As with the other national system options, there is no clear-cut impact on burnout with universal healthcare. At present, no existing national healthcare system is structured to reduce burnout among healthcare providers.
