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.
Cochrane is a British international charitable organisation formed to synthesize medical research findings to facilitate evidence-based choices about health interventions involving health professionals, patients and policy makers. It includes 53 review groups that are based at research institutions worldwide. Cochrane has approximately 30,000 volunteer experts from around the world.
Community health refers to simple health services that are delivered by laymen outside hospitals and clinics. Community health is also the subset of public health that is taught to and practiced by clinicians as part of their normal duties. Community health volunteers and community health workers work with primary care providers to facilitate entry into, exit from and utilization of the formal health system by community members.
A medical guideline is a document with the aim of guiding decisions and criteria regarding diagnosis, management, and treatment in specific areas of healthcare. Such documents have been in use for thousands of years during the entire history of medicine. However, in contrast to previous approaches, which were often based on tradition or authority, modern medical guidelines are based on an examination of current evidence within the paradigm of evidence-based medicine. They usually include summarized consensus statements on best practice in healthcare. A healthcare provider is obliged to know the medical guidelines of their profession, and has to decide whether to follow the recommendations of a guideline for an individual treatment.
Evidence-based design (EBD) is the process of constructing a building or physical environment based on scientific research to achieve the best possible outcomes. Evidence-based design is especially important in evidence-based medicine, where research has shown that environment design can affect patient outcomes. It is also used in architecture, interior design, landscape architecture, facilities management, education, and urban planning. Evidence-based design is part of the larger movement towards evidence-based practices.
Population health has been defined as "the health outcomes of a group of individuals, including the distribution of such outcomes within the group". It is an approach to health that aims to improve the health of an entire human population. It has been described as consisting of three components. These are "health outcomes, patterns of health determinants, and policies and interventions".
A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. A systematic review extracts and interprets data from published studies on the topic, then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based conclusion. For example, a systematic review of randomized controlled trials is a way of summarizing and implementing evidence-based medicine.
Patient safety is a discipline that emphasizes safety in health care through the prevention, reduction, reporting and analysis of error and other types of unnecessary harm that often lead to adverse patient events. The frequency and magnitude of avoidable adverse events, often known as patient safety incidents, experienced by patients was not well known until the 1990s, when multiple countries reported significant numbers of patients harmed and killed by medical errors. Recognizing that healthcare errors impact 1 in every 10 patients around the world, the World Health Organization (WHO) calls patient safety an endemic concern. Indeed, patient safety has emerged as a distinct healthcare discipline supported by an immature yet developing scientific framework. There is a significant transdisciplinary body of theoretical and research literature that informs the science of patient safety with mobile health apps being a growing area of research.
A clinical pathway, also known as care pathway, integrated care pathway, critical pathway, or care map, is one of the main tools used to manage the quality in healthcare concerning the standardisation of care processes. It has been shown that their implementation reduces the variability in clinical practice and improves outcomes. Clinical pathways aim to promote organised and efficient patient care based on evidence-based medicine, and aim to optimise outcomes in settings such as acute care and home care. A single clinical pathway may refer to multiple clinical guidelines on several topics in a well specified context.
Lifestyle medicine (LM) is a branch of medicine focused on preventive healthcare and self-care dealing with prevention, research, education, and treatment of disorders caused by lifestyle factors and preventable causes of death such as nutrition, physical inactivity, chronic stress, and self-destructive behaviors including the consumption of tobacco products and drug or alcohol abuse. The goal of LM is to improve individuals' health and wellbeing by applying the 6 pillars of lifestyle medicine (nutrition, regular physical activity, restorative sleep, stress management, avoidance of risky substances, and positive social connection) to prevent chronic conditions such as cardiovascular diseases, diabetes, metabolic syndrome and obesity. By focusing on these 6 areas to improve health, LM can prevent 80% of chronic illnesses and non-communicable diseases (NCD).
Patient participation is a trend that arose in answer to medical paternalism. Informed consent is a process where patients make decisions informed by the advice of medical professionals.
Critical appraisal in evidence based medicine, is the use of explicit, transparent methods to assess the data in published research, applying the rules of evidence to factors such as internal validity, adherence to reporting standards, conclusions, generalizability and risk-of-bias. Critical appraisal methods form a central part of the systematic review process. They are used in evidence synthesis to assist clinical decision-making, and are increasingly used in evidence-based social care and education provision.
The National Institute for Health and Care Research (NIHR) is the British government’s major funder of clinical, public health, social care and translational research. With a budget of over £1.2 billion in 2020–21, its mission is to "improve the health and wealth of the nation through research". The NIHR was established in 2006 under the government's Best Research for Best Health strategy, and is funded by the Department of Health and Social Care. As a research funder and research partner of the NHS, public health and social care, the NIHR complements the work of the Medical Research Council. NIHR focuses on translational research, clinical research and applied health and social care research.
David M. Eddy is an American physician, mathematician, and healthcare analyst who has done seminal work in mathematical modeling of diseases, clinical practice guidelines, and evidence-based medicine. Four highlights of his career have been summarized by the Institute of Medicine of the National Academy of Sciences: "more than 25 years ago, Eddy wrote the seminal paper on the role of guidelines in medical decision-making, the first Markov model applied to clinical problems, and the original criteria for coverage decisions; he was the first to use and publish the term 'evidence-based'."
The National Center for Healthcare Leadership (NCHL) is an American 501(c)(3) nonprofit organization that promotes evidence-based best practices within the healthcare leadership, organizational development, and international healthcare spaces. NCHL operates three organizational membership programs – the Leadership Excellence Networks (LENS), the National Council on Administrative Fellowships (NCAF), and the US Cooperative for International Patient Programs (USCIPP) – that in total comprise over 160 US hospitals and health systems and nearly 40 graduate health management programs at US institutions.
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
Alternative medicine describes any practice which aims to achieve the healing effects of medicine, but which lacks biological plausibility and is untested or untestable. Complementary medicine (CM), complementary and alternative medicine (CAM), integrated medicine or integrative medicine (IM), and holistic medicine are among many rebrandings of the same phenomenon.
