A health system, health care system or healthcare system is an organization of people, institutions, and resources that delivers health care services to meet the health needs of target populations.
Health care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care. The term includes work done in providing primary care, secondary care, and tertiary care, as well as in public health.
Health informatics is the study and implementation of computer structures and algorithms to improve communication, understanding, and management of medical information. It can be viewed as branch of engineering and applied science.
Primary care is the day-to-day healthcare given by a health care provider. Typically this provider acts as the first contact and principal point of continuing care for patients within a healthcare system, and coordinates other specialist care that the patient may need. Patients commonly receive primary care from professionals such as a primary care physician, a physician assistant, a physical therapist, or a nurse practitioner. In some localities, such a professional may be a registered nurse, a pharmacist, a clinical officer, or an Ayurvedic or other traditional medicine professional. Depending on the nature of the health condition, patients may then be referred for secondary or tertiary care.
The Agency for Healthcare Research and Quality is one of twelve agencies within the United States Department of Health and Human Services (HHS). The agency is headquartered in North Bethesda, Maryland, a suburb of Washington, D.C.. It was established as the Agency for Health Care Policy and Research (AHCPR) in 1989 as a constituent unit of the Public Health Service (PHS) to enhance the quality, appropriateness, and effectiveness of health care services and access to care by conducting and supporting research, demonstration projects, and evaluations; developing guidelines; and disseminating information on health care services and delivery systems.
Primary health care (PHC) is "essential health care" that is based on scientifically sound and socially acceptable methods and technology. This makes universal health care accessible to all individuals and families in a community. PHC initiatives allow for the full participation of community members in implementation and decision making. Services are provided at a cost that the community and the country can afford at every stage of their development in the spirit of self-reliance and self-determination. In other words, PHC is an approach to health beyond the traditional health care system that focuses on health equity-producing social policy. PHC includes all areas that play a role in health, such as access to health services, environment and lifestyle. Thus, primary healthcare and public health measures, taken together, may be considered as the cornerstones of universal health systems. The World Health Organization, or WHO, elaborates on the goals of PHC as defined by three major categories, "empowering people and communities, multisectoral policy and action; and primary care and essential public health functions as the core of integrated health services[1]." Based on these definitions, PHC cannot only help an individual after being diagnosed with a disease or disorder, but can actively contribute to preventing such issues by understanding the individual as a whole.
Polyclinics in England were intended to offer a greater range of services than were offered by current general practitioner (GP) practices and local health centres. In addition to traditional GP services they would offer extended urgent care, healthy living services, community mental health services and social care, whilst being more accessible and less medicalised than hospitals. A variety of models were proposed, ranging from networks of existing clinics to larger premises with several colocated general practitioner (GP) practices, more extensive facilities and additional services provided by allied healthcare professionals.
NHS Scotland, sometimes styled NHSScotland, is the publicly funded healthcare system in Scotland and one of the four systems that make up the National Health Service in the United Kingdom. It operates 14 territorial NHS boards across Scotland, supported by seven special non-geographic health boards, and Public Health Scotland.
A Patient Safety Organization (PSO) is a group, institution, or association that improves medical care by reducing medical errors. Common functions of patient safety organizations are data collection, analysis, reporting, education, funding, and advocacy. A PSO differs from a Federally designed Patient Safety Organization (PSO), which provides health care providers in the U.S. privilege and confidentiality protections for efforts to improve patient safety and the quality of patient care delivery
The Health and Social Care Select Committee is a Departmental Select Committee of the British House of Commons, the lower house of the United Kingdom Parliament. Its remit is to examine the policy, administration and expenditure of the Department of Health and Social Care (DHSC) and its associated agencies and public bodies. The Clerks of the Committee are Previn Desai and Joanna Dodd.
The medical home, also known as the patient-centered medical home (PCMH), is a team-based health care delivery model led by a health care provider to provide comprehensive and continuous medical care to patients with a goal to obtain maximal health outcomes. It is described in the "Joint Principles" as "an approach to providing comprehensive primary care for children, youth and adults."
Unwarranted variation in health care service delivery refers to medical practice pattern variation that cannot be explained by illness, medical need, or the dictates of evidence-based medicine. It is one of the causes of low value care often ignored by health systems.
An integrated delivery system (IDS), also known as integrated delivery network (IDN), is a health system with a goal of logical integration of the delivery (provision) of health care as opposed to a fragmented system or a disorganized lack of system.
Healthcare in Denmark is largely provided by the local governments of the five regions, with coordination and regulation by central government, while nursing homes, home care, and school health services are the responsibility of the 98 municipalities. Some specialised hospital services are managed centrally.
Collaborative Care is a healthcare philosophy and movement focussed on a systematised way of managing care and treatment for people with chronic conditions. Related ideas include: Integrated care, Primary Care Behavioral Health, Integrated care systems, and shared care. There are many studies establishing the long-term clinical and cost-effectiveness of collaborative care for people with physical–mental comorbidity. Nearly half of all people with a diagnosable mental health problem also have a long-term physical condition.
The Improvement Science Research Network (ISRN) is a research network for academics and physicians who are conducting studies in the new medical field of improvement science.
The primary care behavioral health (PCBH) consultation model is a psychological approach to population-based clinical health care that is simultaneously co-located, collaborative, and integrated within the primary care clinic. The goal of PCBH is to improve and promote overall health within the general population. This approach is important because approximately half of all patients in primary care present with psychiatric comorbidities, and 60% of psychiatric illness is treated in primary care.
The Donabedian model is a conceptual model that provides a framework for examining health services and evaluating quality of health care. According to the model, information about quality of care can be drawn from three categories: “structure,” “process,” and “outcomes." Structure describes the context in which care is delivered, including hospital buildings, staff, financing, and equipment. Process denotes the transactions between patients and providers throughout the delivery of healthcare. Finally, outcomes refer to the effects of healthcare on the health status of patients and populations. Avedis Donabedian, a physician and health services researcher at the University of Michigan, developed the original model in 1966. While there are other quality of care frameworks, including the World Health Organization (WHO)-Recommended Quality of Care Framework and the Bamako Initiative, the Donabedian Model continues to be the dominant paradigm for assessing the quality of health care.
Health care quality is a level of value provided by any health care resource, as determined by some measurement. As with quality in other fields, it is an assessment of whether something is good enough and whether it is suitable for its purpose. The goal of health care is to provide medical resources of high quality to all who need them; that is, to ensure good quality of life, cure illnesses when possible, to extend life expectancy, and so on. Researchers use a variety of quality measures to attempt to determine health care quality, including counts of a therapy's reduction or lessening of diseases identified by medical diagnosis, a decrease in the number of risk factors which people have following preventive care, or a survey of health indicators in a population who are accessing certain kinds of care.
Learning health systems (LHS) are health and healthcare systems in which knowledge generation processes are embedded in daily practice to improve individual and population health. At its most fundamental level, a learning health system applies a conceptual approach wherein science, informatics, incentives, and culture are aligned to support continuous improvement, innovation, and equity, and seamlessly embed knowledge and best practices into care delivery
