The enhancement of health through the prevention, diagnosis, treatment, amelioration, or cure of disease, illness, injury, and other physical and mental limitations in humans is known as healthcare or health care delivery. Health professionals and other related health areas provide healthcare. Health care includes the following professions: medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, physical therapy, occupational therapy, athletic training, and other related fields. The phrase encompasses work in public health as well as primary, secondary, and tertiary care delivery.
Different nations, communities, and people may have different levels of access to healthcare due to social, economic, and health policy factors. "The timely use of personal health services to achieve the best possible health outcomes" is the definition of providing health care services.[3] There are a number of factors to take into account when it comes to healthcare access, such as financial constraints (like insurance coverage), geographical and logistical obstacles (like extra transportation costs and the need for paid time off work), sociocultural norms, and individual constraints (like a lack of health literacy, low income, or difficulty communicating with healthcare providers).[4] Restrictions on health care services have a negative impact on the usage of medical services, the effectiveness of treatments, and the final result (death rates and overall well-being).
Organizations created to address the health requirements of certain populations are known as health systems. As per the World Health Organization (WHO), a functional healthcare system necessitates a funding source, a workforce that is both well-trained and appropriately compensated, dependable data to support policy and decision-making, and well-maintained healthcare facilities to provide high-quality medications and technologies.
An effective healthcare system can play a major role in the economic growth and industrialization of a nation. Globally, the promotion of people's general physical and mental health and well-being is significantly influenced by health care.[5] One instance of this was the 1980 WHO declaration of the global eradication of smallpox, which made medical history's first disease to be eradicated through intentional healthcare treatments.
