QUESTIONS ASKING FOR PERSONALIZED MEDICAL ADVICE ARE OFF-TOPIC. CONSULT YOUR PHYSICIAN. Healthcare refers to the system or systems used to deliver medical care to patients. It may be a monolithic, government controlled system (like the NHS in some parts of the UK) or a mixed system of providers and insurers (as in the US). Healthcare is the way the delivery of medical science is organised (at least for the purposes of tagging on this site).
