hospital in the UK .]] hospital in the US .]] A hospital is an institution for Health Care , often but not always providing for longer-term patient stays. Today, hospitals are usually funded by the state, health organizations ( For Profit or Non-profit ), Health Insurance s or Charities , including direct charitable donations. In history, however, they were often founded and funded by religious orders or charitable individuals and leaders. Hospitals are nowadays staffed by professional Physician s, Surgeon s and Nurse s, whereas in history, this work was usually done by the founding religious orders or by volunteers. ETYMOLOGY During the Middle Ages the hospital could serve other functions, such as Almshouse for the poor, or hostel for Pilgrims . The name comes from German ''hospes'' (host), which is also the root for the English words '' Hotel '', '' Hostel '', and '' Hospitality ''. The modern word ''hotel'' derives from the French word ''hostel'', which featured a silent ''s'', which was eventually removed from the word; French for ''hospital'' is ''hôpital''. Grammar of the word Differs slightly depending on the dialect. In the U.S., ''hospital'' usually requires an article; in Britain and elsewhere, the word is normally used without an article when it is the object of a preposition and when referring to a patient ("in/to the hospital" vs. "in/to hospital"); in Canada, both usages are found. TYPES intervention, showing the highly technical equipment of modern hospitals.]] Some Patient s in a hospital come just for Diagnosis and/or therapy and then leave ('outpatients'); while others are 'admitted' and stay overnight or for several weeks or months ('inpatients'). Hospitals are usually distinguished from other types of medical facilities by their ability to admit and care for inpatients. Specialized Types of specialized hospitals include Trauma Center s, Children's Hospitals , seniors' ( Geriatric ) hospitals, and hospitals for dealing with specific medical needs such as Psychiatric problems (see Psychiatric Hospital ), certain disease categories, and so forth. A hospital may be a single building or a Campus . Some hospitals are affiliated with Universities for Medical Research and the training of medical personnel. Worldwide, most hospitals are run on a Non-profit basis by governments or charities. Within the United States , most hospitals are not-for-profit. Clinics A medical facility smaller than a hospital is called a '' Clinic '', and is often run by a Government Agency for health services or a private Partnership of physicians (in nations where private practice is allowed). Clinics generally provide only outpatient services. Other facilities Many hospitals have Hospital Volunteer programs where people (usually Student s and Senior Citizen s) can Volunteer and provide various ancillary services. Hospitals may be required by law to have backup power generators, in case of a blackout. Additionally they may be placed on special high priority segments of the public works (utilities) infrastructure to ensure continuity of care during a state of emergency. HISTORY in a hospital. German Engraving from 1682.]] Early history In ancient cultures, religion and medicine were linked. The earliest known institutions aiming to provide cure were Egyptian temples. Greek Temple s dedicated to the healer-god Asclepius might admit the sick, who would wait for guidance from the god in a dream. The Romans adopted his worship. Under his Roman name Æsculapius, he was provided with a temple ( 291 BC ) on an island in the Tiber in Rome , where similar rites were performed.Roderick E. McGrew, ''Encyclopedia of Medical History'' (Macmillan 1985), pp.134-5. Ancient Asia The Sinhalese ( Sri Lanka ns) are perhaps responsible for introducing the concept of dedicated hospitals to the world. According to the Mahavamsa , the ancient chronicle of Sinhalese royalty written in the 6th century A.D., King Pandukabhaya (4th century BC) had lying-in-homes and hospitals (Sivikasotthi-Sala) built in various parts of the country. This is the earliest documentary evidence we have of institutions specifically dedicated to the care of the sick anywhere in the world.Prof. Arjuna Aluvihare, "Rohal Kramaya Lovata Dhayadha Kale Sri Lankikayo" ''Vidhusara Science Magazine'', Nov. 1993. Mihintale Hospital is perhaps the oldest in the world.Heinz E Müller-Dietz, ''Historia Hospitalium'' (1975). Institutions created specifically to care for the ill also appeared early in India . King Ashoka founded 18 hospitals c. 230 BC. There were physicians and nursing staff, and the expense was borne by the royal treasury.Roderick E. McGrew, ''Encyclopedia of Medical History'' (Macmillan 1985), p.135. State-supported hospitals later appeared in China during the first millennium A.D. The first Teaching Hospital where students were authorized to methodically practice on patients under the supervision of physicians as part of their education, was the Academy Of Gundishapur in the Persian Empire . One expert has argued that "to a very large extent, the credit for the whole hospital ''system'' must be given to Persia". C. Elgood, ''A Medical History of Persia'', (Cambridge Univ. Press), p. 173. Roman Empire The Romans created ''valetudinaria'' for the care of sick slaves, gladiators and soldiers around , University Of Newcastle Upon Tyne , Sunday 20 December 1998 The adoption of Christianity as the state religion of the empire drove an expansion of the provision of care. The First Council Of Nicaea in 325 A.D. urged the Church to provide for the poor, sick, widows and strangers. It ordered the construction of a hospital in every cathedral town. Among the earliest were those built by the physician Saint Sampson in Constantinople and by Basil, Bishop Of Caesarea . The latter was attached to a Monastery and provided lodgings for poor and travelers, as well as treating the sick and infirm. There was a separate section for lepers.Roderick E. McGrew, ''Encyclopedia of Medical History'' (Macmillan 1985), p.135. Medieval Europe was the largest hospital in colonial America.]] in France showing the often close connection between historical hospitals and churches.]] Medieval hospitals in bishop Masona in 580 at Mérida , was a ''xenodochium'' designed as an inn for travellers (mostly pilgrims to the shrine of Eulalia Of Mérida ) as well as a hospital for citizens and local farmers. The hospital's endowment consisted of farms to feed its patients and guests. Medieval Arabia Meanwhile Muslim hospitals developed a high standard of care between the eighth and twelfth centuries A.D. Hospitals built in Baghdad in the ninth and tenth centuries employed up to twenty-five staff physicians and had separate wards for different conditions. Sultan Bayazid II built a Mental Hospital and medical Madrasa in Edirne , and a number of other early hospitals were also built in Turkey. Unlike in Greek temples to healing gods, the clerics working in these facilities employed scientific methodology far beyond that of their contemporaries in their treatment of patients.'' Turkish Contributions to Scientific Work in Islam '' - Sayili, Aydin, ''Foundation For Science, Technology and Civilisation'', Septermber 2004, Page 9 According to Sir John Bagot Glubb, “By Mamun's time medical schools were extremely active in Baghdad. The first free public hospital was opened in Baghdad during the Caliphate of Haroon-ar-Rashid. As the system developed, physicians and surgeons were appointed who gave lectures to medical students and issued diplomas to those who were considered qualified to practice. The first hospital in Egypt was opened in 872 AD and thereafter public hospitals sprang up all over the empire from Spain and the Maghrib to Persia.” North America The Hospital De Jesús Nazareno in Mexico City is the oldest hospital in Mexico . It was founded in 1524 with the economic support of Conquistador Hernán Cortés to care for poor Spanish soldiers and the native inhabitants. The first hospital in North America north of Mexico is the Hôtel-Dieu De Québec . It was established in New France in 1639 by three Augustinians from l'Hôtel-Dieu de Dieppe in France. The project of the niece of Cardinal De Richelieu was granted a royal charter by King Louis XIII and staffed by colonial physician Robert Giffard De Moncel . Modern era In Europe the medieval concept of Christian care evolved during the sixteenth and seventeenth centuries into a secular one, but it was in the eighteenth century that the modern hospital began to appear, serving only medical needs and staffed with physicians and surgeons. The Charité (founded in Berlin in 1710 ) is an early example. Guy's Hospital was founded in London in 1724 from a bequest by wealthy merchant Thomas Guy . Other hospitals sprang up in London and other British cities over the century, many paid for by private subscriptions. In the British American colonies the Pennsylvania General Hospital was chartered in Philadelphia in 1751 , after £2,000 from private subscription was matched by funds from the Assembly.Roderick E. McGrew, ''Encyclopedia of Medical History'' (Macmillan 1985), p.139. When the Viennese General Hospital ( Allgemeines Krankenhaus ) opened in 1784 (instantly becoming the world's largest hospital), physicians acquired a new facility that gradually developed into the most important research center. During the 19th century, the Second Viennese Medical School emerged with the contributions of physicians such as Carl Freiherr Von Rokitansky , Josef Škoda , Ferdinand Ritter Von Hebra and Ignaz Philipp Semmelweis . Basic medical science expanded and specialization advanced. Furthermore, the first dermatology, eye, as well as ear, nose and throat clinics in the world were founded in Vienna - it was the birth of specialized medicine. By the mid- Nineteenth Century most of Europe and the United States had established a variety of public and private hospital systems. In Continental Europe the new hospitals were generally built and run from public funds. The National Health Service , the principle provider of healthcare in the United Kingdom, was founded in 1948 . In the United States the traditional hospital is a Non-profit Hospital , usually sponsored by a religious denomination. One of the earliest of these "almshouses" in what would become the United States was started by William Penn in Philadelphia in 1713 . These hospitals are tax-exempt due to their charitable purpose, but provide only a minimum of charitable medical care. They are supplemented by large Public Hospital s in major cities and research hospitals often affiliated with a medical school. In the late twentieth century, chains of For-profit Hospital s arose in the USA. In the modern era, hospitals are, broadly, either funded by the government of the country in which they are situates, or survice financially by competing in the private sector. For example, In the United Kingdom, there remains in existence a comprehensive National Health Service free at the point of delivery and funded by the state, so hospital care is easily available to all (although there is a tendency for "waiting lists" to be generated). On the other hand, the USA has followed a largely private-based approach to providing hospital care, and while this has produced some of the best hospitals in the world a very large proportion of Americans have little or no access to healthcare services of adequate quality. As quality of healthcare has increasingly become an issue around the world, hospitals have increasingly had to pay serious attention to this. External assessment of quality is one of the most powerful ways of assessing the quality of healthcare, and hospital accreditation is one means by which this is achieved. Increasingly, in many parts of the world such accreditation is courced from other countries, a phenomenon known as International Healthcare Accreditation . SUPPORT INFRASTRUCTURE The surgical, special procedures, radiological, Intensive Care Unit , and patient rooms typically have medical gases, emergency and normal electrical power, and heating, air conditioning and ventilation systems. Electrical The reliability of the electrical power systems that serve a hospital is important. In order to provide higher electrical reliability, the National Institutes Of Health , NIH, requires that all secondary substations > 500 kVA at their Bethesda, MD campus be the spot network type. The Spot Network Substations cost more than other arrangements. Information Pneumatic Tube conveying systems are often used to move the actual paper prescriptions for medicines to the Pharmacies, and to move medicines, especially intra-venous, IV, bags to the patient care rooms. Tissue samples can be sent to the Laboratory. Medical notes can be transcribed, printed, and then transported via a Pneumatic Tube Conveying System. As measured by the weight of the item be transferred, the 15 cm (6”) diameter tube systems have about 225% of the lifting and moving capacity of a 10 cm (4”) system. When the seals are new, the 10 cm tube carriers will move a 1 kg (2+ pound) IV bag. But when the seals on the tube carriers are worn, the tubes can stop moving in the piping, and require a trained technician to recover the tube carrier. SEE ALSO
