or s, do not necessarily work in hospitals. Some primary care services are delivered within hospitals. Depending on the organization and policies of the national health system, patients may be required to see a primary care provider for a referral (medicine), referral before they can access secondary care. In countries that operate under a mixed market health care system, some physicians limit their practice to secondary care by requiring patients to see a primary care provider first. This restriction may be imposed under the terms of the payment agreements in private or group health insurance plans. In other cases, Medical specialty, medical specialists may see patients without a referral, and patients may decide whether self-referral is preferred. In other countries patient self-referral to a medical specialist for secondary care is rare as prior referral from another physician (either a primary care physician or another specialist) is considered necessary, regardless of whether the funding is from Health insurance, private insurance schemes or national health insurance. Allied health professions, Allied health professionals, such as physical therapy, physical therapists, respiratory therapists, occupational therapists, Speech and language pathology, speech therapists, and dietitians, also generally work in secondary care, accessed through either patient self-referral or through physician referral.


Tertiary care

Tertiary care is specialized consultative health care, usually for inpatients and on referral from a primary or secondary health professional, in a facility that has personnel and facilities for advanced medicine, medical investigation and treatment, such as a tertiary referral hospital. Examples of tertiary care services are cancer management, neurosurgery, cardiac surgery, plastic surgery, treatment for severe burns, advanced neonatology services, palliative, and other complex medical and surgical interventions.Emory University

Quaternary care

Clinical research, Experimental medicine and some types of uncommon diagnosis, diagnostic or surgery, surgical procedures are considered quaternary care. These services are usually only offered in a limited number of regional or national health care centers.


Home and community care

Many types of health care interventions are delivered outside of health facilities. They include many interventions of

interest, such as food safety surveillance, distribution of condoms and needle-exchange programme, needle-exchange programs for the prevention of transmissible diseases. They also include the services of professionals in residential and community settings in support of self-care, home care, long-term care, assisted living, treatment for substance use disorders among other types of health and social care services. Community Physical therapy, rehabilitation services can assist with mobility and independence after the loss of limbs or loss of function. This can include prosthesis, prostheses, orthotics, or wheelchairs. Many countries, especially in the west, are dealing with aging populations, so one of the priorities of the health care system is to help seniors live full, independent lives in the comfort of their own homes. There is an entire section of health care geared to providing seniors with help in day-to-day activities at home such as transportation to and from doctor's appointments along with many other activities that are essential for their health and well-being. Although they provide home care for older adults in cooperation, family members and care workers may harbor diverging attitudes and values towards their joint efforts. This state of affairs presents a challenge for the design of ICT (information and communication technology) for home care. Because statistics show that over 80 million Americans have taken time off of their primary employment to care for a loved one, many countries have begun offering programs such as the Consumer Directed Personal Assistant Program to allow family members to take care of their loved ones without giving up their entire income. With obesity in children rapidly becoming a major concern, health services often set up programs in schools aimed at educating children about nutritional eating habits, making physical education a requirement and teaching young adolescents to have a positive self-image.


Ratings

Health care ratings are ratings or evaluations of health care used to evaluate the process of care and health care structures and/or outcomes of health care services. This information is translated into report cards that are generated by quality organizations, nonprofit, consumer groups and media. This evaluation of quality is based on measures of: * hospital quality * health plan quality * physician quality
MERHS
healthcare treatment * quality for other health professionals * of patient experience


Related sectors

Health care extends beyond the delivery of services to patients, encompassing many related sectors, and is set within a bigger picture of financing and governance structures.


Health system

A health system, also sometimes referred to as health care system or healthcare system is the organization of people, institutions, and resources that deliver health care services to populations in need.


Healthcare industry

The healthcare 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, patient advocates or other allied health professions. In addition, according to industry and market classifications, such as the Global Industry Classification Standard and the Industry Classification Benchmark, health care includes many categories of medical equipment, instruments and services including biotechnology, diagnostic laboratories and substances, drug manufacturing and delivery. For example, pharmaceuticals and other medical devices are the leading high technology exports of Europe and the United States. The United States dominates the biopharmaceutical field, accounting for three-quarters of the world's biotechnology revenues.


Health care research

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 A disease is a particular abnormal condition that negatively affects the structure A structure is an arrangement and organization of interrelated elements in a material object or system A system is a group of Interaction, interacting ...
through medical diagnosis, diagnosis and effective treatment. Many important advances have been made through health research, biomedical research and pharmaceutical research, which form the basis for evidence-based medicine and evidence-based practice in health care delivery. Health care research frequently engages directly with patients, and as such issues for whom to engage and how to engage with them become important to consider when seeking to actively include them in studies. While single best practice does not exist, the results of a systematic review on patient engagement suggest that research methods for patient selection need to account for both patient availability and willingness to engage. Health services research can lead to greater efficiency and equitable delivery of health care interventions, as advanced through the social model of disability, social model of health and disability, which emphasizes the societal changes that can be made to make populations healthier. Results from health services research often form the basis of evidence-based policy in health care systems. Health services research is also aided by initiatives in the field of artificial intelligence for the development of systems of health assessment that are clinically useful, timely, sensitive to change, culturally sensitive, low-burden, low-cost, built into standard procedures, and involve the patient.


Health care financing

There are generally five primary methods of funding health care systems: # General taxation to the state, county or municipality # social insurance, Social health insurance # Voluntary or private health insurance # Out-of-pocket expenses, Out-of-pocket payments # Donations to health charities In most countries, there is a mix of all five models, but this varies across countries and over time within countries. Aside from financing mechanisms, an important question should always be how much to spend on healthcare. For the purposes of comparison, this is often expressed as the percentage of GDP spent on healthcare. In OECD countries for every extra $1000 spent on healthcare, life expectancy falls by 0.4 years. A similar correlation is seen from the analysis carried out each year by Bloomberg. Clearly this kind of analysis is flawed in that life expectancy is only one measure of a health system's performance, but equally, the notion that more funding is better is not supported. In 2011, the health care industry consumed an average of 9.3 percent of the gross domestic product, GDP or United States dollar, US$ 3,322 (Purchasing power parity, PPP-adjusted) per capita across the 34 members of Organisation for Economic Co-operation and Development, OECD countries. The US (17.7%, or US$ PPP 8,508), the Netherlands (11.9%, 5,099), France (11.6%, 4,118), Germany (11.3%, 4,495), Canada (11.2%, 5669), and Switzerland (11%, 5,634) were the top spenders, however life expectancy, life expectancy in total population at birth was highest in Switzerland (82.8 years), Japan and Italy (82.7), Spain and Iceland (82.4), France (82.2) and Australia (82.0), while OECD's average exceeds 80 years for the first time ever in 2011: 80.1 years, a gain of 10 years since 1970. The US (78.7 years) ranges only on place 26 among the 34 OECD member countries, but has the highest costs by far. All OECD countries have achieved universal (or almost universal) health coverage, except the US and Mexico. (see also Health system#International comparisons, international comparisons.) In the United States, where around 18% of GDP is spent on health care, the Commonwealth Fund analysis of spend and quality shows a clear correlation between worse quality and higher spending.


Administration and regulation

The Health administration, management and administration of health care is vital to the delivery of health care services. In particular, the practice of health professionals and the operation of health care institutions is typically Regulation, regulated by national or state/provincial authorities through appropriate regulatory bodies for purposes of quality assurance. Most countries have credentialing staff in regulatory boards or health departments who document the Health professional requisites, certification or licensing of health workers and their work history.


Health information technology

Health information technology (HIT) is "the application of information processing involving both computer hardware and software that deals with the storage, retrieval, sharing, and use of health care information, data, and knowledge for communication and decision making." Health information technology components: * Electronic health record, Electronic Health Record (EHR) - An EHR contains a patient's comprehensive medical history, and may include records from multiple providers. * Electronic Medical Record (EMR) - An EMR contains the standard medical and clinical data gathered in one's provider's office. * Personal health record, Personal Health Record (PHR) - A PHR is a patient's medical history that is maintained privately, for personal use. * Medical practice management software, Medical Practice Management software (MPM) - is designed to streamline the day-to-day tasks of operating a medical facility. Also known as practice management software or practice management system (PMS). * Health information exchange, Health Information Exchange (HIE) - Health Information Exchange allows health care professionals and patients to appropriately access and securely share a patient's vital medical information electronically.
