health care
Quick Summary
Health care encompasses efforts to maintain, restore, or promote physical, mental, and emotional well-being, typically by trained professionals. It involves organizing health services to maximize the benefits of available knowledge and technology for individuals, families, and communities.12
Levels of Health Care
Health services are often structured in a tiered system:
* Primary Health Care: This is the first point of contact for individuals with the healthcare system. It aims to be universally accessible, scientifically sound, and socially acceptable, often provided by physicians in developed countries and sometimes by non-medical personnel in developing nations.2
* Secondary Health Care: Patients who require specialized knowledge or tests are referred to this level, often involving local or regional hospitals and consultants.2
* Tertiary Health Care: This highest tier involves highly specialized services, typically found in teaching hospitals or dedicated units for specific groups like women or children.2
Many countries strive for universal health care, ensuring all citizens have access to medical services, often funded through taxes. This can take various forms, including single-payer systems, social health insurance, and national health insurance. Electronic health records (EHRs) are digital systems designed to house and share patient information, aiming to improve care quality and reduce errors, though challenges like cost and interoperability persist.34
