Ahospital is a healthcare institution providing patient treatment with specializedhealth science and auxiliary healthcare staff and medical equipment.[1] The best-known type of hospital is the general hospital, which typically has anemergency department to treat urgent health problems ranging from fire and accident victims to a sudden illness. A district hospital typically is the major health care facility in its region, with many beds forintensive care and additional beds for patients who need long-term care.
Ateaching hospital combines assistance to people with teaching to health science students andauxiliary healthcare students. A health science facility smaller than a hospital is generally called a clinic. Hospitals have a range of departments (e.g. surgery andurgent care) and specialist units such ascardiology. Some hospitals haveoutpatient departments and some have chronic treatment units. Common support units include apharmacy,pathology, andradiology.
Hospitals are typically funded bypublic funding, health organizations (for-profit or nonprofit),health insurance companies, or charities, including direct charitable donations. Historically, hospitals were often founded and funded byreligious orders, or by charitable individuals and leaders.[3]
Hospitals are currently staffed by professional physicians, surgeons, nurses, andallied health practitioners. In the past, however, this work was usually performed by the members of founding religious orders or byvolunteers. However, there are various Catholic religious orders, such as theAlexians and theBon Secours Sisters that still focus on hospital ministry in the late 1990s, as well as several other Christian denominations, including the Methodists and Lutherans, which run hospitals.[4] In accordance with the original meaning of the word, hospitals were original "places of hospitality", and this meaning is still preserved in the names of some institutions such as theRoyal Hospital Chelsea, established in 1681 as a retirement and nursing home for veteran soldiers.
During the Middle Ages, hospitals served different functions from modern institutions in that they werealmshouses for the poor,hostels forpilgrims, or hospital schools. The word "hospital" comes from theLatinhospes, signifying a stranger or foreigner, hence a guest. Another noun derived from this,hospitium came to signify hospitality, that is the relation between guest and shelterer, hospitality, friendliness, and hospitable reception. Bymetonymy, the Latin word then came to mean a guest-chamber, guest's lodging, aninn.[5]Hospes is thus the root for the English wordshost (where thep was dropped for convenience of pronunciation)hospitality,hospice,hostel, andhotel. The latter modern word derives from Latin via theOld French romance wordhostel, which developed a silents, which letter was eventually removed from the word, the loss of which is signified by acircumflex in themodern French wordhôtel. The German wordSpital shares similar roots.
Some patients go to a hospital just fordiagnosis, treatment, or therapy and then leave ("outpatients") without staying overnight; while others are "admitted" and stay overnight or for several days or weeks or months ("inpatients"). Hospitals are usually distinguished from other types of medical facilities by their ability to admit and care for inpatients whilst the others, which are smaller, are often described asclinics.
The best-known type of hospital is the general hospital, also known as an acute-care hospital. These facilities handle many kinds of disease and injury, and normally have an emergency department (sometimes known as "accident & emergency") ortrauma center to deal with immediate and urgent threats to health. Larger cities may have several hospitals of varying sizes and facilities. Some hospitals, especially in the United States and Canada, have their own ambulance service.
A district hospital typically is the major health care facility in its region, with large numbers of beds forintensive care,critical care, and long-term care.
In California, "district hospital" refers specifically to a class of healthcare facility created shortly afterWorld War II to address a shortage of hospital beds in many local communities.[6][7] Even today, district hospitals are the sole public hospitals in 19 of California's counties,[6] and are the sole locally accessible hospital within nine additional counties in which one or more other hospitals are present at a substantial distance from a local community.[6] Twenty-eight of California's rural hospitals and 20 of its critical-access hospitals are district hospitals.[7] They are formed by local municipalities, have boards that are individually elected by their local communities, and exist to serve local needs.[6][7] They are a particularly important provider of healthcare to uninsured patients and patients withMedi-Cal (which is California'sMedicaid program, serving low-income persons, somesenior citizens, persons withdisabilities, children infoster care, and pregnant women).[6][7] In 2012, district hospitals provided $54 million in uncompensated care in California.[7]
InGermany, specialised hospitals are calledFachkrankenhaus; an example isFachkrankenhaus Coswig (thoracic surgery). In India, specialty hospitals are known assuper-specialty hospitals and are distinguished from multispecialty hospitals which are composed of several specialties.[citation needed]
Specialised hospitals can help reducehealth care costs compared to general hospitals. For example,Narayana Health's cardiac unit inBangalore specialises in cardiac surgery and allows for a significantly greater number of patients. It has 3,000 beds and performs 3,000 paediatric cardiac operations annually, the largest number in the world for such a facility.[2][9] Surgeons are paid on a fixed salary instead of per operation, thus when the number of procedures increases, the hospital is able to take advantage ofeconomies of scale and reduce its cost per procedure.[9] Each specialist may also become more efficient by working on one procedure like aproduction line.[2]
Clinics generally provide onlyoutpatient services, but some may have a few inpatient beds and a limited range of services that may otherwise be found in typical hospitals.
Many units have both a nursing and a medical director that serve as administrators for their respective disciplines within that unit. For example, within an intensive care nursery, a medical director is responsible for physicians and medical care, while the nursing manager is responsible for all the nurses and nursing care.
TheCOVID-19 pandemic stimulated the development of virtual wards across the BritishNHS. Patients are managed at home, monitoring their own oxygen levels using an oxygen saturation probe if necessary and supported by telephone.West Hertfordshire Hospitals NHS Trust managed around 1200 patients at home between March and June 2020 and planned to continue the system after COVID-19, initially for respiratory patients.[12]Mersey Care NHS Foundation Trust started a COVID Oximetry@Home service in April 2020. This enables them to monitor more than 5000 patients a day in their own homes. The technology allows nurses, carers, or patients to record and monitor vital signs such as blood oxygen levels.[13]
In earlyIndia,Fa Xian, a Chinese Buddhist monk who travelled across Indiac. AD 400, recorded examples of healing institutions.[14] According to theMahavamsa, the ancient chronicle of Sinhalese royalty, written in the sixth century AD, KingPandukabhaya of Sri Lanka (r. 437–367 BC) had lying-in-homes and hospitals (Sivikasotthi-Sala).[15] Ahospital and medical training center also existed atGundeshapur, a major city in southwest of theSassanid Persian Empire founded in AD 271 byShapur I.[16] Inancient Greece, temples dedicated to the healer-godAsclepius, known asAsclepeion functioned as centers of medical advice, prognosis, and healing.[17] The Asclepeia spread to theRoman Empire. While public healthcare was non-existent in the Roman Empire, military hospitals calledvaletudinaria did exist stationed in military barracks and would serve the soldiers and slaves within the fort.[18] Evidence exists that some civilian hospitals, while unavailable to the Roman population, were occasionally privately built in extremely wealthy Roman households located in the countryside for that family, although this practice seems to have ended in 80 AD.[19]

Ruins of a two thousand-year-old hospital were discovered in the historical city ofAnuradhapuraMihintale Sri Lanka.
The declaration ofChristianity as an accepted religion in the Roman Empire drove an expansion of the provision of care.[20] Following theFirst Council of Nicaea in AD 325 construction of a hospital in every cathedral town was begun, including among the earliest hospitals bySaint Sampson inConstantinople and byBasil, bishop of Caesarea in modern-day Turkey.[21] By the twelfth century, Constantinople had two well-organised hospitals, staffed by doctors who were both male and female. Facilities included systematic treatment procedures and specialised wards for various diseases.[22]

The earliest general hospital in the Islamic world was built in 805 inBaghdad byHarun Al-Rashid.[23][24] By the 10th century, Baghdad had five more hospitals, whileDamascus had six hospitals by the 15th century, andCórdoba alone had 50 major hospitals, many exclusively for the military, by the end of the 15th century.[25] The Islamicbimaristan served as a center of medical treatment, as wellnursing home andlunatic asylum. It typically treated the poor, as the rich would have been treated in their own homes.[26] Hospitals in this era were the first to require medical licenses for doctors, and compensation for negligence could be made.[27][28] Hospitals were forbidden by law to turn away patients who were unable to pay.[29] These hospitals were financially supported bywaqfs, as well as state funds.[25]
In India,public hospitals existed at least since the reign ofFiruz Shah Tughlaq in the 14th century. TheMughal emperorJahangir in the 17th century established hospitals in large cities at government expense with records showing salaries and grants for medicine being paid for by the government.[30]
In China, during theSong dynasty, the state began to take on social welfare functions previously provided by Buddhist monasteries and instituted public hospitals,hospices anddispensaries.[31]
In Europe the medieval concept of Christian care evolved during the 16th and 17th centuries into a secular one. InEngland, after thedissolution of the monasteries in 1540 by KingHenry VIII, the church abruptly ceased to be the supporter of hospitals, and only by direct petition from the citizens of London, were the hospitalsSt Bartholomew's,St Thomas's andSt Mary of Bethlehem's (Bedlam) endowed directly by the crown; this was the first instance of secular support being provided for medical institutions.
Other hospitals sprang up in London and other British cities over the century, many paid for by private subscriptions. St Bartholomew's in London was rebuilt from 1730 to 1759,[38] and the London Hospital, Whitechapel, opened in 1752.
These hospitals represented a turning point in the function of the institution; they began to evolve from being basic places of care for the sick to becoming centers of medical innovation and discovery and the principal place for theeducation and training of prospective practitioners. Some of the era's greatest surgeons and doctors worked and passed on their knowledge at the hospitals.[39] They also changed from being mere homes of refuge to being complex institutions for the provision and advancement of medicine and care for sick. TheCharité was founded in Berlin in 1710 by KingFrederick I of Prussia as a response to an outbreak of plague.
When theVienna General Hospital opened in 1784 as the world's largest hospital, physicians acquired a new facility that gradually developed into one of the most important research centers.[41]
AnotherEnlightenment era charitable innovation was the dispensary; these would issue the poor with medicines free of charge. The London Dispensary opened its doors in 1696 as the first such clinic in theBritish Empire. The idea was slow to catch on until the 1770s,[42] when many such organisations began to appear, including thePublic Dispensary of Edinburgh (1776), the Metropolitan Dispensary and Charitable Fund (1779) and theFinsbury Dispensary (1780). Dispensaries were also opened in New York 1771,Philadelphia 1786, and Boston 1796.[43]
TheRoyal Naval Hospital, Stonehouse,Plymouth, was a pioneer of hospital design in having "pavilions" to minimize the spread of infection.John Wesley visited in 1785, and commented "I never saw anything of the kind so complete; every part is so convenient, and so admirably neat. But there is nothing superfluous, and nothing purely ornamented, either within or without." This revolutionary design was made more widely known byJohn Howard, the philanthropist. In 1787 the French government sent two scholar administrators,Coulomb andTenon, who had visited most of the hospitals in Europe.[44] They were impressed and the "pavilion" design was copied in France and throughout Europe.
Florence Nightingale pioneered the modern profession of nursing during theCrimean War when she set an example of compassion, commitment to patient care and diligent and thoughtful hospital administration. The first official nurses' training programme, the Nightingale School for Nurses, was opened in 1860, with the mission of training nurses to work in hospitals, to work with the poor and to teach.[47] Nightingale was instrumental in reforming the nature of the hospital, by improvingsanitation standards and changing the image of the hospital from a place the sick would go to die, to an institution devoted to recuperation and healing. She also emphasised the importance ofstatistical measurement for determining the success rate of a given intervention and pushed foradministrative reform at hospitals.[48]
By the late 19th century, the modern hospital was beginning to take shape with a proliferation of a variety of public and private hospital systems. By the 1870s, hospitals had more than trebled their original average intake of 3,000 patients. In continental Europe the new hospitals generally were built and run from public funds. TheNational Health Service, the principal provider of health care in the United Kingdom, was founded in 1948. During the nineteenth century, the Second Viennese Medical School emerged with the contributions of physicians such asCarl Freiherr von Rokitansky,Josef Škoda,Ferdinand Ritter von Hebra, andIgnaz Philipp Semmelweis. Basic medical science expanded and specialisation advanced. Furthermore, the first dermatology, eye, as well as ear, nose, and throat clinics in the world were founded inVienna, being considered as the birth of specialised medicine.[49]
By the late 19th and early 20th centuries, medical advancements such asanesthesia and sterile techniques that could make surgery less risky, and the availability of more advanced diagnostic devices such asX-rays, continued to make hospitals a more attractive option for treatment.[50]
Modern hospitals measure various efficiency metrics such as occupancy rates, the average length of stay, time to service, patient satisfaction, physician performance, patient readmission rate, inpatient mortality rate, andcase mix index.[51]
In theUnited States, the number of hospitalizations grew to its peak in 1981 with 171 admissions per 1,000 Americans and 6,933 hospitals.[50] This trend subsequently reversed, with the rate of hospitalization falling by more than 10% and the number of US hospitals shrinking from 6,933 in 1981 to 5,534 in 2016.[52] Occupancy rates also dropped from 77% in 1980 to 60% in 2013.[53] Among the reasons for this are the increasing availability of more complex care elsewhere such as at home or the physicians' offices and also the less therapeutic and more life-threatening image of the hospitals in the eyes of the public.[50][54] In the US, a patient may sleep in a hospital bed, but be considered outpatient and "under observation" if not formally admitted.[55]
In the U.S., inpatient stays are covered under Medicare Part A, but a hospital might keep a patient under observation which is only covered under Medicare Part B, and subjects the patient to additional coinsurance costs.[55] In 2013, theCenter for Medicare and Medicaid Services (CMS) introduced a "two-midnight" rule for inpatient admissions,[56] intended to reduce an increasing number of long-term "observation" stays being used for reimbursement.[55] This rule was later dropped in 2018.[56] In 2016 and 2017, healthcare reform and a continued decline in admissions resulted in US hospital-based healthcare systems performing poorly financially.[57] Microhospitals, with bed capacities of between eight and fifty, are expanding in the United States.[58] Similarly, freestanding emergency rooms, which transfer patients that require inpatient care to hospitals, were popularised in the 1970s[59] and have since expanded rapidly across the United States.[59]
In theUnited Kingdom, the National Health Service delivers health care to legal residents funded by the state "free at the point of delivery", and emergency care free to anyone regardless of nationality or status. Due to the need for hospitals to prioritise their limited resources, there is a tendency in countries with such systems for 'waiting lists' for non-crucial treatment, so those who can afford it may take out private health care to access treatment more quickly.[63]
In theUnited States, hospitals typically operate privately and in some cases on afor-profit basis, such asHCA Healthcare.[64] The list of procedures and their prices are billed with achargemaster; however, these prices may be lower for health care obtained withinhealthcare networks.[65] Legislation requires hospitals to provide care to patients in life-threatening emergency situations regardless of the patient's ability to pay.[66] Privately funded hospitals which admit uninsured patients in emergency situations incur direct financial losses, such as in the aftermath ofHurricane Katrina.[64]
As the quality of health care has increasingly become an issue around the world, hospitals have increasingly had to pay serious attention to this matter. Independent external assessment of quality is one of the most powerful ways to assess this aspect of health care, andhospital accreditation is one means by which this is achieved. In many parts of the world such accreditation is sourced from other countries, a phenomenon known asinternational healthcare accreditation, by groups such asAccreditation Canada inCanada, theJoint Commission in the U.S., theTrent Accreditation Scheme inGreat Britain, and theHaute Autorité de santé (HAS) inFrance. InEngland, hospitals are monitored by theCare Quality Commission. In 2020, they turned their attention to hospital food standards after seven patient deaths fromlisteria linked to pre-packaged sandwiches and salads in 2019, saying "Nutrition and hydration is part of a patient's recovery."[67]
TheWorld Health Organization reported in 2011 that being admitted to a hospital was far riskier than flying. Globally, the chance of a patient being subject to a treatment error in a hospital was about 10%, and the chance of death resulting from an error was about one in 300. according toLiam Donaldson. 7% of hospitalised patients in developed countries, and 10% in developing countries, acquire at least onehealth care-associated infection. In the U.S., 1.7 million infections are acquired in hospital each year, leading to 100,000 deaths, figures much worse than in Europe where there were 4.5 million infections and 37,000 deaths.[68]
Modern hospital buildings are designed to minimise the effort of medical personnel and the possibility of contamination while maximising the efficiency of the whole system. Travel time for personnel within the hospital and the transportation of patients between units is facilitated and minimised. The building also should be built to accommodate heavy departments such as radiology and operating rooms while space for special wiring, plumbing, and waste disposal must be allowed for in the design.[69]
However, many hospitals, even those considered "modern", are the product of continual and often badly managed growth over decades or even centuries, with utilitarian new sections added on as needs and finances dictate. As a result, Dutch architectural historian Cor Wagenaar has called many hospitals:
"... built catastrophes, anonymous institutional complexes run by vast bureaucracies, and totally unfit for the purpose they have been designed for ... They are hardly ever functional, and instead of making patients feel at home, they produce stress and anxiety."[70]
Some newer hospitals now try to re-establish design that takes the patient's psychological needs into account, such as providing more fresh air, better views and more pleasant colour schemes. These ideas harken back to the late eighteenth century, when the concept of providing fresh air and access to the 'healing powers of nature' were first employed by hospital architects in improving their buildings.[70]
The research ofBritish Medical Association is showing that good hospital design can reduce patient's recovery time. Exposure to daylight is effective in reducing depression.[71] Single-sex accommodation help ensure that patients are treated in privacy and with dignity. Exposure to nature and hospital gardens is also important – looking out windows improves patients' moods and reduces blood pressure and stress level. Open windows in patient rooms have also demonstrated some evidence of beneficial outcomes by improving airflow and increased microbial diversity.[72][73] Eliminating long corridors can reduce nurses' fatigue and stress.[74]
Another ongoing major development is the change from a ward-based system (where patients are accommodated in communal rooms, separated by movable partitions) to one in which they are accommodated in individual rooms. The ward-based system has been described as very efficient, especially for the medical staff, but is considered to be more stressful for patients and detrimental to their privacy. A major constraint on providing all patients with their own rooms is however found in the higher cost of building and operating such a hospital; this causes some hospitals to charge for private rooms.[75]
The medical center at theUniversity of Virginia shows the growing trend for modern architecture in hospitals.

Arranged around the monastery were concentric rings of buildings in which the life and work of the monastic community was ordered. The outer ring of buildings served as a hostel in which travellers were received and boarded. The inner ring served as a place where the monastic community could care for the sick, the poor and the infirm. Monks were frequently familiar with the medicine available at that time, growing medicinal plants on the monastery grounds and applying remedies as indicated. As such, many of the practicing physicians of the Middle Ages were also clergy.

In 931 AD Caliph Al-Muqtadir learned that a patient had died in Baghdad as a result of a physician's error. Consequently, he ordered Sinan ibn Thabit to examine all those who practiced the art of healing. Of the 860 medical practitioners he examined, 160 failed. From that time on, licensing examinations were required and administered in various places. Licensing boards were set up under a government official called Muhtasib, or inspector general. The chief physician gave oral and practical examinations, and if the young physician was successful, the Muhtasib administered the Hippocratic Oath and issued a license to practice medicine.
