Health care extends beyond the
delivery of services to patients, encompassing many related sectors, and set
within a bigger picture of financing and governance structures, including health
cover.
The health care industry incorporates
several sectors that are dedicated to providing health care
services and products. As a basic framework for defining the sector, the United
Nations' International Standard Industrial Classification categorizes health care
as generally consisting of hospital activities, medical and dental practice
activities, and "other human health activities". The last class
involves activities of, or under the supervision of, nurses, midwives,
physiotherapists, scientific or diagnostic laboratories, pathology clinics,
residential health facilities, or other allied health professions, e.g. in the
field of optometry, hydrotherapy, medical massage, yoga therapy, music therapy,
occupational therapy, speech therapy, chiropody, homeopathy, chiropractics,
acupuncture, etc. If you are interested in FREE e-book, “Develop

Health care or healthcare is the
diagnosis, treatment, and prevention of disease, illness, injury, and other
physical and mental impairments in human beings. Health care
is delivered by practitioners in allied health, dentistry, midwifery
(obstetrics), medicine, nursing, optometry, pharmacy, psychology and other health
professions. It refers to the work done in providing primary care, secondary
care, and tertiary care, as well as in public health.
Health home care involves knowing how
to self treat, choosing the doctor and understanding the tests and procedures
you undergo. People enjoy longer life spans many of them develop serious
chronic illnesses on the way. They manage to live near normal lives, thanks to
advances in medical technology. But the quality of their lives
compromised sadly. Some patients lose flexibility, while others lose mobility
and still others encounter severe pain. This is where home health care
equipment comes to rescue.
The quantity and quality of many health care
interventions are improved through the results of science, such as advanced through
the medical model of health which focuses on the eradication of illness through
diagnosis and effective treatment. Many important advances have been made
through health research, including biomedical research and pharmaceutical
research, which form the basis for evidence based medicine and evidence based
practice in health care delivery.
Achieving and maintaining health is an
ongoing process, shaped by both the evolution of health care
knowledge and practices as well as personal strategies and organized
interventions for staying healthy.
In
recent years alternative health care (health care that doesn't involve
pumping your body full of chemicals that were never supposed to be there) has
become increasingly popular as its benefits have begun to be recognized among
the medical community, but there are still plenty of things your doctor isn't
telling you.
Senior people are brought to health care when their children cannot take care of them.
