Inverse Care Law
The inverse care law is the principle that the availability of good medical or social care tends to vary inversely with the need of the population served. Proposed by Julian Tudor Hart in 1971, the term has since been widely adopted. It is considered a landmark publication in the history of ''The Lancet''. The name is a pun on inverse-square law, a term and concept from physics. The law states that: ''"The availability of good medical care tends to vary inversely with the need for it in the population served. This ... operates more completely where medical care is most exposed to market forces, and less so where such exposure is reduced."'' Hart later paraphrased his argument: "To the extent that health care becomes a commodity it becomes distributed just like champagne. That is rich people get lots of it. Poor people don’t get any of it." The Inverse Care Law is a key issue in debates about the provision of health care and health inequality. As Frank Dobson put it when he ...

Julian Tudor Hart
Alan Julian Macbeth Tudor-Hart (9 March 1927 – 1 July 2018), commonly known as Julian Tudor Hart, was a British doctor who worked as a general practitioner (GP) in Wales for 30 years. He was involved with research and wrote many books and scientific articles. Early life Hart was born in London on 9 March 1927, the son of Alexander Tudor-Hart and Alison Macbeth. He studied medicine at Cambridge University and in London, graduating in 1952. He is a descendant of American businessman Frederic Tudor and Ephraim Hart, a Bavarian Jew who became a prominent merchant in New York, and was reportedly partners with John Jacob Astor. The name was originally Hirz. His paternal grandfather, the Canadian artist Percyval Hart, married his Polish-French cousin Éléonora Délia Julie Aimée Hart Kleczkowska, and later changed the family surname to Tudor-Hart. Kleczkowska was the daughter of diplomat Michel Alexandre Cholewa, comte Kleczkowski (Michał Kleczkowski; 1818–1886) and grand ...

The Lancet
''The Lancet'' is a weekly peer-reviewed general medical journal and one of the oldest of its kind. It is also the world's highest-impact academic journal. It was founded in England in 1823. The journal publishes original research articles, review articles ("seminars" and "reviews"), editorials, book reviews, correspondence, as well as news features and case reports. ''The Lancet'' has been owned by Elsevier since 1991, and its editor-in-chief since 1995 has been Richard Horton. The journal has editorial offices in London, New York City, and Beijing. History ''The Lancet'' was founded in 1823 by Thomas Wakley, an English surgeon who named it after the surgical instrument called a lancet (scalpel). Members of the Wakley family retained editorship of the journal until 1908. In 1921, ''The Lancet'' was acquired by Hodder & Stoughton. Elsevier acquired ''The Lancet'' from Hodder & Stoughton in 1991. Impact According to the ''Journal Citation Reports'', the journal has a 202 ...

Inverse-square Law
In science, an inverse-square law is any scientific law stating that a specified physical quantity is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space. Radar energy expands during both the signal transmission and the reflected return, so the inverse square for both paths means that the radar will receive energy according to the inverse fourth power of the range. To prevent dilution of energy while propagating a signal, certain methods can be used such as a waveguide, which acts like a canal does for water, or how a gun barrel restricts hot gas expansion to one dimension in order to prevent loss of energy transfer to a bullet. Formula In mathematical notation the inverse square law can be expressed as an intensity (I) varying as a function of distance (d) from some centre. The intensity is ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Health Inequality
Health equity arises from access to the social determinants of health, specifically from wealth, power and prestige. Individuals who have consistently been deprived of these three determinants are significantly disadvantaged from health inequities, and face worse health outcomes than those who are able to access certain resources. It is not equity to simply provide every individual with the same resources; that would be equality. In order to achieve health equity, resources must be allocated based on an individual need-based principle. According to the World Health Organization, "Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". The quality of health and how health is distributed among economic and social status in a society can provide insight into the level of development within that society. Health is a basic human right and human need, and all human rights are interconnected. Thus, health must be discusse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Dobson
Frank Gordon Dobson (15 March 1940 – 11 November 2019) was a British Labour Party politician. As Member of Parliament (MP) for Holborn and St. Pancras from 1979 to 2015, he served in the Cabinet as Secretary of State for Health from 1997 to 1999, and was official Labour Party candidate for Mayor of London in 2000, though finishing third in the election behind Conservative Steven Norris and the winner, Labour-turned-Independent Ken Livingstone. Dobson stood down at the 2015 general election. Early life and career Dobson was born in 1940 in Dunnington, York, the son of Irene (''née'' Shortland) and John William Dobson. His father, a railwayman, died when Dobson was sixteen years old. Dobson attended Dunnington County Church of England Primary School and the Archbishop Holgate Grammar School (now Archbishop Holgate's School), where he was supported after the death of his father by a grant from the county council. He then studied economics at the London School of Economics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secretary Of State For Health
The secretary of state for health and social care, also referred to as the health secretary, is a secretary of state in the Government of the United Kingdom, responsible for the work of the Department of Health and Social Care. The incumbent is a member of the Cabinet of the United Kingdom. The position can trace its roots back to the nineteenth century, and has been a secretary of state position since 1968. For 30 years, from 1988 to 2018, the position was titled Secretary of State for Health, before Prime Minister Theresa May added "and Social Care" to the designation in the 2018 British cabinet reshuffle. The office holder works alongside the other health and social care ministers. The corresponding shadow minister is the shadow secretary of state for health and social care, and the secretary of state is also scrutinised by the Health and Social Care Select Committee. The current health secretary is Steve Barclay who was appointed by Rishi Sunak on 25 October 2022. Res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health Policy
Health policy can be defined as the "decisions, plans, and actions that are undertaken to achieve specific healthcare goals within a society".World Health Organization''Health Policy'' accessed 22 March 2011(Web archive)/ref> According to the World Health Organization, an explicit health policy can achieve several things: it defines a vision for the future; it outlines priorities and the expected roles of different groups; and it builds consensus and informs people. Different approaches Health policy often refers to the health-related content of a policy. Understood in this sense, there are many categories of health policies, including global health policy, public health policy, mental health policy, health care services policy, insurance policy, personal healthcare policy, pharmaceutical policy, and policies related to public health such as vaccination policy, tobacco control policy or breastfeeding promotion policy.

Inverse Benefit Law
The inverse benefit law states that the ratio of benefits to harms among patients taking new drugs tends to vary inversely with how extensively a drug is marketed. Two Americans, Howard Brody and Donald Light, have defined the inverse benefit law, inspired by Tudor Hart's inverse care law. A drug effective for a serious disorder is less and less effective as it is promoted for milder cases and for other conditions for which the drug was not approved. Although effectiveness becomes more diluted, the risks of harmful side effects persist, and thus the benefit-harm ratio worsens as a drug is marketed more widely. The inverse benefit law highlights the need for comparative effectiveness research and other reforms to improve evidence-based prescribing. State of affairs The law is manifested through 6 basic marketing strategies: * reducing thresholds for diagnosing disease, * relying on surrogate endpoints, * exaggerating safety claims, * exaggerating efficacy Efficacy is the ab ...

Patient Safety
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.

Public Health
Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The ''public'' can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of ''health'' takes into account physical, psychological, and social well-being.What is the WHO definition of health? from the Preamble to the Constitution of WHO as adopted by the International Health Conference, New York, 19 June - 22 July 1946; signed on ...

Health Economics
Health economics is a branch of economics concerned with issues related to efficiency, effectiveness, value and behavior in the production and consumption of health and healthcare. Health economics is important in determining how to improve health outcomes and lifestyle patterns through interactions between individuals, healthcare providers and clinical settings. In broad terms, health economists study the functioning of healthcare systems and health-affecting behaviors such as smoking, diabetes, and obesity. One of the biggest difficulties regarding healthcare economics is that it does not follow normal rules for economics. Price and Quality are often hidden by the third-party payer system of insurance companies and employers. Additionally, QALY (Quality Adjusted Life Years), one of the most commonly used measurements for treatments, is very difficult to measure and relies upon assumptions that are often unreasonable.
