Information resources


Information resources
Sound information plays an increasingly critical role in the delivery of modern health care and efficiency of health systems. Health informatics – the intersection of information science, medicine and healthcare – deals with the resources, devices, and methods required to optimize the acquisition and use of information in health and biomedicine. Necessary tools for proper health information coding and management include clinical guidelines, formal medical terminologies, and computers and other information and communication technologies. The kinds of data processed may include patients' medical records, hospital administration and clinical functions, and human resources information.

The use of health information lies at the root of evidence-based policy and evidence-based management in health care. Increasingly, information and communication technologies are being utilised to improve health systems in developing countries through: the standardisation of health information; computer-aided diagnosis and treatment monitoring; informing population groups on health and treatment.

Management
The management of any health system is typically directed through a set of policies and plans adopted by government, private sector business and other groups in areas such as personal healthcare delivery and financing, pharmaceuticals, health human resources, and public health.

Public health is concerned with threats to the overall health of a community based on population health analysis. The population in question can be as small as a handful of people, or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). Public health is typically divided into epidemiology, biostatistics and health services. Environmental, social, behavioral, and occupational health are also important subfields.

Today, most governments recognize the importance of public health programs in reducing the incidence of disease, disability, the effects of ageing and health inequities, although public health generally receives significantly less government funding compared with medicine. For example, most countries have a vaccination policy, supporting public health programs in providing vaccinations to promote health. Vaccinations are voluntary in some countries and mandatory in some countries. Some governments pay all or part of the costs for vaccines in a national vaccination schedule.

The rapid emergence of many chronic diseases, which require costly long-term care and treatment, is making many health managers and policy makers re-examine their healthcare delivery practices. An important health issue facing the world currently is HIV/AIDS. Another major public health concern is diabetes. In 2006, according to the World Health Organization, at least 171 million people worldwide suffered from diabetes. Its incidence is increasing rapidly, and it is estimated that by the year 2030, this number will double. A controversial aspect of public health is the control of tobacco smoking, linked to cancer and other chronic illnesses.

Antibiotic resistance is another major concern, leading to the reemergence of diseases such as tuberculosis. The World Health Organization, for its World Health Day 2011 campaign, is calling for intensified global commitment to safeguard antibiotics and other antimicrobial medicines for future generations.

Aspects of health

Health Health is "a state of complete physical, mental, and social well-being and not merely the absence of disease" according to the World Health Organization (WHO). Physical is about the body. Mental is about how people think and feel. Social talks about how people live with other people. It is about family, work, school, and friends. Aspects of health Physical health Physical fitness refers to good body health. It is dependent on genetic determinators and also on social, economic and ecological factors. That means, one´s genes are partly responsible for one´s physical health, but also other circumstances: where you live, how clean or polluted your water and the air around you is and also how good your social and medical system is. It is also the result of regular exercise, proper diet and nutrition, and proper rest for physical recovery. A person who is physically fit will be able to walk or run without getting breathless and they will be able to carry out the a...

Providers Healthcare providers are institutions or individuals providing healthcare services. Individuals including health professionals and allied health professions can be self-employed or working as an employee in a hospital, clinic, or other health care institution, whether government operated, private for-profit, or private not-for-profit (e.g. non-governmental organization). They may also work outside of direct patient care such as in a government health department or other agency, medical laboratory, or health training institution. Examples of health workers are doctors, nurses, midwives, dietitians, paramedics, dentists, medical laboratory technologists, therapists, psychologists, pharmacists, chiropractors, optometrists, community health workers, traditional medicine practitioners, and others. Financial resources There are generally five primary methods of funding health systems:  1.general taxation to the state, county or municipality  2.national health in...
