A medical specialty is a branch of medical practice that is focused on a defined group of patients, diseases, skills, or philosophy . Examples include those branches of medicine that deal exclusively with children ( pediatrics ), cancer ( oncology ), laboratory medicine ( pathology ), or primary care ( family medicine ). After completing medical school or other basic training, physicians or surgeons and other clinicians usually further their medical education in a specific specialty of medicine by completing a multiple-year residency to become a specialist.
96-496: Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass ), to reconstruct or improve aesthetics and appearance ( cosmetic surgery ), or to remove unwanted tissues ( body fat , glands , scars or skin tags ) or foreign bodies . The act of performing surgery may be called
192-473: A radiosurgical procedure (e.g. irradiation of a tumor). Surgical procedures are commonly categorized by urgency, type of procedure, body system involved, the degree of invasiveness, and special instrumentation. Inpatient surgery is performed in a hospital, and the person undergoing surgery stays at least one night in the hospital after the surgery. Outpatient surgery occurs in a hospital outpatient department or freestanding ambulatory surgery center, and
288-525: A surgical procedure or surgical operation , or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments , surgical facility or surgical nurse . Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery. Modern surgical operations typically require
384-412: A surgical team that typically consists of the surgeon, the surgical assistant, an anaesthetist (often also complemented by an anaesthetic nurse ), a scrub nurse (who handles sterile equipment), a circulating nurse and a surgical technologist , while procedures that mandate cardiopulmonary bypass will also have a perfusionist . All surgical procedures are considered invasive and often require

This was especially true in the poorest countries, which account for over one-third of the population but only 3.5% of all surgeries that occur worldwide. It emphasized the need to significantly improve the capacity for Bellwether procedures – laparotomy , caesarean section , open fracture care – which are considered a minimum level of care that first-level hospitals should be able to provide in order to capture
576-497: A Component of Universal Health Coverage . The Lancet Commission for Global Surgery outlined the need for access to "available, affordable, timely and safe" surgical and anesthesia care; dimensions paralleled in ICESCR General Comment No. 14, which similarly outlines need for available, accessible, affordable and timely healthcare. Surgical treatments date back to the prehistoric era. The oldest for which there

These may be used by governmental agencies, insurance companies , patient groups, or health care facilities . Individuals who use or have used psychiatric services may alternatively refer to themselves as consumers, users, or survivors . In nursing homes and assisted living facilities,
768-612: A component of universal health coverage." This not only mandated the WHO to prioritize strengthening the surgical and anesthesia care globally, but also led to governments of the member states recognizing the urgent need for increasing capacity in surgery and anesthesia. Additionally, the third edition of Disease Control Priorities (DCP3), published in 2015 by the World Bank , declared surgery as essential and featured an entire volume dedicated to building surgical capacity. Data from WHO and
864-459: A decade, medical errors are even more likely to happen in a doctor's office or outpatient clinic or center. A day patient (or day-patient ) is a patient who is using the full range of services of a hospital or clinic but is not expected to stay the night. The term was originally used by psychiatric hospital services using of this patient type to care for people needing support to make the transition from in-patient to out-patient care. However,
960-496: A formal hospital admission or an overnight stay, and this is called outpatient surgery or day surgery, which has many benefits including lowered healthcare cost , reducing the amount of medication prescribed, and using the physician's or surgeon's time more efficiently. Outpatient surgery is suited best for more healthy patients undergoing minor or intermediate procedures (limited urinary-tract , eye , or ear, nose, and throat procedures and procedures involving superficial skin and

#17327729313001152-567: A list of specialties recognized in the European Union, and by extension, the European Economic Area. There is substantial overlap between some of the specialties and it is likely that for example "Clinical radiology" and "Radiology" refer to a large degree to the same pattern of practice across Europe. In this table, as in many healthcare arenas, medical specialties are organized into the following groups: According to
1248-528: A military physician". The researchers were impressed by the complexity of the brain surgical operation. In 1991 at the Polystylon fort in Greece, researchers discovered the head of a Byzantine warrior of the 14th century. Analysis of the lower jaw revealed that a surgery has been performed, when the warrior was alive, to the jaw which had been badly fractured and it tied back together until it healed. During
1344-469: A particular organ. Others are based mainly around a set of techniques, such as radiology , which was originally based around X-rays . The age range of patients seen by any given specialist can be quite variable. Pediatricians handle most complaints and diseases in children that do not require surgery, and there are several subspecialties (formally or informally) in pediatrics that mimic the organ-based specialties in adults. Pediatric surgery may or may not be
1440-513: A period of postoperative care (sometimes intensive care ) for the patient to recover from the iatrogenic trauma inflicted by the procedure. The duration of surgery can span from several minutes to tens of hours depending on the specialty , the nature of the condition, the target body parts involved and the circumstance of each procedure, but most surgeries are designed to be one-off interventions that are typically not intended as an ongoing or repeated type of treatment. In British colloquialism,
1536-497: A peripheral IV line is placed, and pre-operative medications (antibiotics, sedatives, etc.) are given. When the patient enters the operating room and is appropriately anesthetized, the team will then position the patient in an appropriate surgical position . If hair is present at the surgical site, it is clipped (instead of shaving). The skin surface within the operating field is cleansed and prepared by applying an antiseptic (typically chlorhexidine gluconate in alcohol, as this
1632-412: A person shows signs of infection and not as a preventative. A systematic review published by Cochrane (organisation) in 2016, though, concluded that topical antibiotics applied over certain types of surgical wounds reduce the risk of surgical site infections, when compared to no treatment or use of antiseptics . The review also did not find conclusive evidence to suggest that topical antibiotics increased
1728-401: A physical exam which did not indicate a chest x-ray. Routine x-ray examination is more likely to result in problems like misdiagnosis, overtreatment, or other negative outcomes than it is to result in a benefit to the person. Likewise, other tests including complete blood count , prothrombin time , partial thromboplastin time , basic metabolic panel , and urinalysis should not be done unless
1824-547: A prehistoric individual from the Indus River valley show evidence of teeth having been drilled. Sushruta Samhita is one of the oldest known surgical texts and its period is usually placed in the first millennium BCE. It describes in detail the examination, diagnosis, treatment, and prognosis of numerous ailments, as well as procedures for various forms of cosmetic surgery, plastic surgery and rhinoplasty . In 1982 archaeologists were able to find significant evidence when
1920-437: A recent study done with lumbar decompressions, the patient's length of stay was decreased by 1–3 days. The use of topical antibiotics on surgical wounds to reduce infection rates has been questioned. Antibiotic ointments are likely to irritate the skin, slow healing, and could increase risk of developing contact dermatitis and antibiotic resistance . It has also been suggested that topical antibiotics should only be used when
2016-464: A risk factor for adverse post-surgical outcomes. It has been linked to many disorders such as obesity hypoventilation syndrome, atelectasis and pulmonary embolism, adverse cardiovascular effects, and wound healing complications. If removable skin closures are used, they are removed after 7 to 10 days post-operatively, or after healing of the incision is well under way. It is not uncommon for surgical drains to be required to remove blood or fluid from

#17327729313002112-475: A rotational internship of about 1.5 to 2 years in various specialties before attaining a medical license. The specialist training lasts 5 years. There are three agencies or organizations in the United States that collectively oversee physician board certification of MD and DO physicians in the United States in the 26 approved medical specialties recognized in the country. These organizations are

Prior to surgery, the person is given a medical examination , receives certain pre-operative tests, and their physical status is rated according to the ASA physical status classification system . If these results are satisfactory,
2304-544: A separate specialty that handles some kinds of surgical complaints in children. A further subdivision is the diagnostic versus therapeutic specialties. While the diagnostic process is of great importance in all specialties, some specialists perform mainly or only diagnostic examinations, such as pathology , clinical neurophysiology , and radiology. This line is becoming somewhat blurred with interventional radiology , an evolving field that uses image expertise to perform minimally invasive procedures. The European Union publishes
2400-647: A specialty of medicine, rather than an accessory field. Basic surgical principles for asepsis etc., are known as Halsteads principles . There were some important advances to the art of surgery during this period. The professor of anatomy at the University of Padua , Andreas Vesalius , was a pivotal figure in the Renaissance transition from classical medicine and anatomy based on the works of Galen , to an empirical approach of 'hands-on' dissection. In his anatomic treaties De humani corporis fabrica , he exposed
2496-467: A weekend, and also, decrease number and level of experience over a weekend. Postoperative pain affects an estimated 80% of people who underwent surgery. While pain is expected after surgery, there is growing evidence that pain may be inadequately treated in many people in the acute period immediately after surgery. It has been reported that incidence of inadequately controlled pain after surgery ranged from 25.1% to 78.4% across all surgical disciplines. There
2592-411: Is a patient who attends an outpatient clinic with no plan to stay beyond the duration of the visit. Even if the patient will not be formally admitted with a note as an outpatient, their attendance is still registered, and the provider will usually give a note explaining the reason for the visit , tests , or procedure / surgery , which should include the names and titles of the participating personnel,
2688-423: Is achieved through major surgical techniques. The internal medicine specialties are the specialties in which the main diagnosis and treatment is never major surgery. In some countries, anesthesiology is classified as a surgical discipline, since it is vital in the surgical process, though anesthesiologists never perform major surgery themselves. Many specialties are organ-based. Many symptoms and diseases come from
2784-417: Is administered to prevent pain from the trauma of cutting, tissue manipulation, application of thermal energy, and suturing. Depending on the type of operation, anesthesia may be provided locally, regionally , or as general anesthesia . Spinal anesthesia may be used when the surgical site is too large or deep for a local block, but general anesthesia may not be desirable. With local and spinal anesthesia,
2880-646: Is among the controversial topics related to surgery in children. Doctors perform surgery with the consent of the person undergoing surgery. Some people are able to give better informed consent than others. Populations such as incarcerated persons , people living with dementia , the mentally incompetent, persons subject to coercion, and other people who are not able to make decisions with the same authority as others, have special needs when making decisions about their personal healthcare, including surgery. Global surgery has been defined as 'the multidisciplinary enterprise of providing improved and equitable surgical care to

Surgical masks are worn by the surgical team to avoid germs on droplets of liquid from their mouths and noses from contaminating the operative site. Work to correct the problem in body then proceeds. This work may involve: Blood or blood expanders may be administered to compensate for blood lost during surgery. Once
3168-442: Is being done to find a solution.As such, surgical care globally has been described as the 'neglected stepchild of global health,' a term coined by Paul Farmer to highlight the urgent need for further work in this area. Furthermore, Jim Young Kim , the former President of the World Bank , proclaimed in 2014 that "surgery is an indivisible, indispensable part of health care and of progress towards universal health coverage." In 2015,
3264-494: Is called inpatient care . The admission to the hospital involves the production of an admission note . The leaving of the hospital is officially termed discharge , and involves a corresponding discharge note , and sometimes an assessment process to consider ongoing needs. In the English National Health Service this may take the form of "Discharge to Assess" - where the assessment takes place after

Prehistoric surgical techniques are seen in Ancient Egypt , where a mandible dated to approximately 2650 BC shows two perforations just below the root of the first molar , indicating the draining of an abscessed tooth . Surgical texts from ancient Egypt date back about 3500 years ago. Surgical operations were performed by priests, specialized in medical treatments similar to today, and used sutures to close wounds. Infections were treated with honey. 9,000-year-old skeletal remains of

The ICESCR Article 12.1 and 12.2 define the human right to health as "the right of everyone to the enjoyment of the highest attainable standard of physical and mental health" In the August 2000, the UN Committee on Economic, Social and Cultural Rights (CESCR) interpreted this to mean "right to
3648-497: Is insufficient evidence to determine if giving opioid pain medication pre-emptively (before surgery) reduces postoperative pain the amount of medication needed after surgery. Postoperative recovery has been defined as an energy‐requiring process to decrease physical symptoms, reach a level of emotional well‐being, regain functions, and re‐establish activities. Moreover, it has been identified that patients who have undergone surgery are often not fully recovered on discharge. In 2011, of
3744-844: Is largely due to differential application. A survey of physicians in the United States came to the result that dermatologists are most satisfied with their choice of specialty followed by radiologists , oncologists , plastic surgeons , and gastroenterologists . In contrast, primary care physicians were the least satisfied, followed by nephrologists , obstetricians/gynecologists , and pulmonologists . Surveys have also revealed high levels of depression among medical students (25 - 30%) as well as among physicians in training (22 - 43%), which for many specialties, continue into regular practice. A UK survey conducted of cancer-related specialties in 1994 and 2002 found higher job satisfaction in those specialties with more patient contact. Rates of burnout also varied by specialty. Inpatient A patient

A key policy framework that arose from this renewed global commitment towards surgical care worldwide is the National Surgical Obstetric and Anesthesia Plan (NSOAP). NSOAP focuses on policy-to-action capacity building for surgical care with tangible steps as follows: (1) analysis of baseline indicators, (2) partnership with local champions, (3) broad stakeholder engagement, (4) consensus building and synthesis of ideas, (5) language refinement, (6) costing, (7) dissemination, and (8) implementation. This approach has been widely adopted and has served as guiding principles between international collaborators and local institutions and governments.

In alignment with the LCoGS call for action, the World Health Assembly adopted the resolution WHA68.15 in 2015 that stated, "Strengthening emergency and essential surgical care and anesthesia as
7296-507: The need for extended care. Assessment of older people before elective surgery can accurately predict the person's recovery trajectories. One frailty scale uses five items: unintentional weight loss, muscle weakness , exhaustion, low physical activity, and slowed walking speed. A healthy person scores 0; a very frail person scores 5. Compared to non-frail elderly people, people with intermediate frailty scores (2 or 3) are twice as likely to have post-surgical complications, spend 50% more time in
7392-425: The patient has gone home. Misdiagnosis is the leading cause of medical error in outpatient facilities. When the U.S. Institute of Medicine 's groundbreaking 1999 report, To Err Is Human , found up to 98,000 hospital patients die from preventable medical errors in the U.S. each year, early efforts focused on inpatient safety. While patient safety efforts have focused on inpatient hospital settings for more than
7488-411: The patient's name and date of birth , signature of informed consent , estimated pre-and post-service time for history and exam (before and after), any anesthesia , medications or future treatment plans needed, and estimated time of discharge absent any (further) complications . Treatment provided in this fashion is called ambulatory care . Sometimes surgery is performed without the need for
7584-410: The person requiring surgery signs a consent form and is given a surgical clearance. If the procedure is expected to result in significant blood loss, an autologous blood donation may be made some weeks prior to surgery. If the surgery involves the digestive system , the person requiring surgery may be instructed to perform a bowel prep by drinking a solution of polyethylene glycol the night before
7680-582: The person who had surgery is discharged the same working day. Office-based surgery occurs in a physician's office, and the person is discharged the same day. At a hospital , modern surgery is often performed in an operating theater using surgical instruments , an operating table , and other equipment. Among United States hospitalizations for non-maternal and non-neonatal conditions in 2012, more than one-fourth of stays and half of hospital costs involved stays that included operating room (OR) procedures. The environment and procedures used in surgery are governed by
7776-413: The principles of aseptic technique : the strict separation of "sterile" (free of microorganisms) things from "unsterile" or "contaminated" things. All surgical instruments must be sterilized , and an instrument must be replaced or re-sterilized if it becomes contaminated (i.e. handled in an unsterile manner, or allowed to touch an unsterile surface). Operating room staff must wear sterile attire ( scrubs ,
7872-421: The procedure is complete, sutures or staples are used to close the incision. Once the incision is closed, the anesthetic agents are stopped or reversed, and the person is taken off ventilation and extubated (if general anesthesia was administered). After completion of surgery, the person is transferred to the post anesthesia care unit and closely monitored. When the person is judged to have recovered from
7968-443: The procedure. People preparing for surgery are also instructed to abstain from food or drink (an NPO order after midnight on the night before the procedure), to minimize the effect of stomach contents on pre-operative medications and reduce the risk of aspiration if the person vomits during or after the procedure. Some medical systems have a practice of routinely performing chest x-rays before surgery. The premise behind this practice
8064-430: The recovery period. A recent post-operative care philosophy has been early ambulation. Ambulation is getting the patient moving around. This can be as simple as sitting up or even walking around. The goal is to get the patient moving as early as possible. It has been found to shorten the patient's length of stay. Length of stay is the amount of time a patient spends in the hospital after surgery before they are discharged. In
8160-458: The reduction of the stillbirth-rate and of infant mortality and for the healthy development of the child" which was subsequently interpreted to mean "requiring measures to improve… emergency obstetric services". Article 12.2d of the ICESCR stipulates the need for "the creation of conditions which would assure to all medical service and medical attention in the event of sickness", and is interpreted in
8256-446: The results of these tests can help evaluate surgical risk. A surgical team may include a surgeon, anesthetist, a circulating nurse, and a "scrub tech", or surgical technician, as well as other assistants who provide equipment and supplies as required. While informed consent discussions may be performed in a clinic or acute care setting, the pre-operative holding area is where documentation is reviewed and where family members can also meet
8352-522: The risk of local skin reactions or antibiotic resistance. Through a retrospective analysis of national administrative data, the association between mortality and day of elective surgical procedure suggests a higher risk in procedures carried out later in the working week and on weekends. The odds of death were 44% and 82% higher respectively when comparing procedures on a Friday to a weekend procedure. This "weekday effect" has been postulated to be from several factors including poorer availability of services on
8448-443: The so-called "noninvasive surgery" ought to be more appropriately called minimally invasive procedures , which usually refers to a procedure that utilizes natural orifices (e.g. most urological procedures) or does not penetrate the structure being excised (e.g. endoscopic polyp excision , rubber band ligation , laser eye surgery ), are percutaneous (e.g. arthroscopy , catheter ablation , angioplasty and valvuloplasty ), or to
8544-453: The surgical service line; the surgical service line costs were $ 17,600 in 2003 and projected to be $ 22,500 in 2013. For hospital stays in 2012 in the United States, private insurance had the highest percentage of surgical expenditure. in 2012, mean hospital costs in the United States were highest for surgical stays. Older adults have widely varying physical health. Frail elderly people are at significant risk of post-surgical complications and
8640-439: The surgical site is anesthetized, but the person can remain conscious or minimally sedated. In contrast, general anesthesia may render the person unconscious and paralyzed during surgery. The person is typically intubated to protect their airway and placed on a mechanical ventilator , and anesthesia is produced by a combination of injected and inhaled agents. The choice of surgical method and anesthetic technique aims to solve
8736-423: The surgical team. Nurses in the preoperative holding area confirm orders and answer additional questions of the family members of the patient prior to surgery. In the pre-operative holding area, the person preparing for surgery changes out of their street clothes and are asked to confirm the details of his or her surgery as previously discussed during the process of informed consent. A set of vital signs are recorded,
8832-599: The surgical wound during recovery. Mostly these drains stay in until the volume tapers off, then they are removed. These drains can become clogged, leading to abscess . Postoperative therapy may include adjuvant treatment such as chemotherapy , radiation therapy , or administration of medication such as anti-rejection medication for transplants. For postoperative nausea and vomiting (PONV), solutions like saline, water, controlled breathing placebo and aromatherapy can be used in addition to medication. Other follow-up studies or rehabilitation may be prescribed during and after
8928-472: The term resident is generally used in lieu of patient . Similarly, those receiving home health care are called clients . The doctor–patient relationship has sometimes been characterized as silencing the voice of patients. It is now widely agreed that putting patients at the centre of healthcare by trying to provide a consistent, informative and respectful service to patients will improve both outcomes and patient satisfaction. When patients are not at
9024-711: The term "surgery" can also refer to the facility where surgery is performed, or simply the office / clinic of a physician , dentist or veterinarian . As a general rule, a procedure is considered surgical when it involves cutting of a person's tissues or closure of a previously sustained wound. Other procedures that do not necessarily fall under this rubric, such as angioplasty or endoscopy , may be considered surgery if they involve "common" surgical procedure or settings, such as use of antiseptic measures and sterile fields, sedation / anesthesia , proactive hemostasis , typical surgical instruments , suturing or stapling . All forms of surgery are considered invasive procedures;
9120-457: The term is now also heavily used for people attending hospitals for day surgery. Because of concerns such as dignity , human rights and political correctness , the term "patient" is not always used to refer to a person receiving health care. Other terms that are sometimes used include health consumer , healthcare consumer , customer or client . However, such terminology may be offensive to those receiving public health care , as it implies
9216-673: The world's population, with its core belief as the issues of need, access and quality". Halfdan T. Mahler , the 3rd Director-General of the World Health Organization (WHO) , first brought attention to the disparities in surgery and surgical care in 1980 when he stated in his address to the World Congress of the International College of Surgeons, "'the vast majority of the world's population has no access whatsoever to skilled surgical care and little
