75-424: Different categories are used in different jurisdictions, but manner of death determinations include everything from very broad categories like "natural" and "homicide" to specific manners like "traffic accident" or "gunshot wound". In some cases an autopsy is performed, either due to general legal requirements, because the medical cause of death is uncertain, upon the request of family members or guardians, or because

150-455: A Wales criminal justice system . England and Wales are treated as a single unit for some purposes, because the two form the constitutional successor to the former Kingdom of England. The continuance of Scots law was guaranteed under the 1706 Treaty of Union that led to the Acts of Union 1707 , and as a consequence English law—and after 1801 , Irish law —continued to be separate. Following

225-417: A body bag or evidence sheet. A new body bag is used for each body to ensure that only evidence from that body is contained within the bag. Evidence sheets are an alternative way to transport the body. An evidence sheet is a sterile sheet that covers the body when it is moved. If it is believed there may be any significant evidence on the hands, for example, gunshot residue or skin under the fingernails ,

300-579: A coroner ( procurator fiscal in Scotland) investigates the case. Coroners are independent judicial officers who investigate deaths reported to them, and subsequently whatever inquiries are necessary to discover the cause of death, this includes ordering a post-mortem examination, obtaining witness statements and medical records, or holding an inquest. In the unified legal jurisdiction of England and Wales , most deaths are certified by doctors without autopsy or coroner involvement. Almost all deaths certified by

375-460: A medical error or a previously unnoticed condition that may endanger the living, such as infectious diseases or exposure to hazardous materials . A study that focused on myocardial infarction (heart attack) as a cause of death found significant errors of omission and commission, i.e. a sizable number of cases ascribed to myocardial infarctions (MIs) were not MIs and a significant number of non-MIs were MIs. A systematic review of studies of

450-418: A pathologist . Only a small portion of deaths require an autopsy to be performed, under certain circumstances. In most cases, a medical examiner or coroner can determine the cause of death. Autopsies are performed for either legal or medical purposes. Autopsies can be performed when any of the following information is desired: For example, a forensic autopsy is carried out when the cause of death may be

525-497: A stroke , heart disease , and sudden organ failure. As organisms age, various health-related consequences arise. In humans, a few examples include slower healing of skin tissue , thickening of blood vessel walls, and a less effective immune system . For example, a fall may be more likely to cause internal bleeding , plaque buildup becomes more likely to cause a heart attack , and a cold may be more likely to result in pneumonia . For much of human history, doctors who lacked

The substantive law of the jurisdiction is English law . The devolved Senedd (Welsh Parliament; Welsh : Senedd Cymru ) – previously named the National Assembly for Wales – was created in 1999 under

675-412: A cause of class I errors. While patients with abdominal pathologic conditions generally complained of abdominal pain, results of an examination of the abdomen were considered unremarkable in most patients, and the symptom was not pursued". There are four main types of autopsy: A forensic autopsy is used to determine the cause, mode, and manner of death. Forensic science involves the application of

750-455: A criminal matter, while a clinical or academic autopsy is performed to find the medical cause of death and is used in cases of unknown or uncertain death, or for research purposes. Autopsies can be further classified into cases where an external examination suffices, and those where the body is dissected and an internal examination is conducted. Permission from next of kin may be required for internal autopsy in some cases. Once an internal autopsy

In the United States , a manner of death is expressed as belonging to one classification of a group of six possible: In some jurisdictions, some more detailed manners may be reported in numbers broken out from the main four or five. For example: In the United Kingdom, when people die, either a doctor writes an acceptable natural cause of death medical certificate , or

900-422: A deceased individual. It is an alternative to medical autopsies, where radiographs are used, for example, Magnetic resonance imaging (MRI) and Computed tomography ( CT scan ) which produce radiographic images in order to determine the cause of death, the nature, and the manner of death, without dissecting the deceased. It can also be used in the identification of the deceased. This method is helpful in determining

975-480: A determination. The Norwegian Medical Association classifies what other jurisdictions might call "undetermined" as "unnatural": A death ruled as homicide or unlawful killing is typically referred to police or prosecutor or equivalent official for investigation and criminal charges if warranted. Deaths caused by capital punishment , though homicides, are generally assumed to be lawful and are not prosecuted. Most deaths due to war are not prosecuted, unless there

1050-420: A doctor is not able to write a death certificate, or when death is believed to result from an unnatural cause . These examinations are performed under a legal authority ( medical examiner , coroner , or procurator fiscal ) and do not require the consent of relatives of the deceased. The most extreme example is the examination of murder victims, especially when medical examiners are looking for signs of death or

1125-444: A pillow in an open casket funeral . The scalp is pulled away from the skull in two flaps with the front flap going over the face and the rear flap over the back of the neck. The skull is then cut with a circular (or semicircular) bladed reciprocating saw to create a "cap" that can be pulled off, exposing the brain. The brain is then observed in situ. Then the brain's connections to the cranial nerves and spinal cord are severed, and

1200-412: A poison) and their quantity. Because post-mortem deterioration of the body, together with the gravitational pooling of bodily fluids, will necessarily alter the bodily environment, toxicology tests may overestimate, rather than underestimate, the quantity of the suspected chemical. Following an in-depth examination of all the evidence , a medical examiner or coroner will assign a manner of death from

1275-683: A public dissection of the body of a former criminal. He asserted and articulated the bones, this became the world's oldest surviving anatomical preparation. It is still displayed at the Anatomical Museum at the University of Basel. In the mid-1800s, Carl von Rokitansky and colleagues at the Second Vienna Medical School began to undertake dissections as a means to improve diagnostic medicine. England and Wales England and Wales ( Welsh : Cymru

1350-443: A separate paper sack is put around each hand and taped shut around the wrist. There are two parts to the physical examination of the body: the external and internal examination. Toxicology , biochemical tests or genetic testing / molecular autopsy often supplement these and frequently assist the pathologist in assigning the cause or causes of death. At many institutions, the person responsible for handling, cleaning, and moving

1425-439: A single category with subcategories, or separate top-level categories. There is no international standard on whether or how to classify a death as natural vs. unnatural. "Mechanism of death" is sometimes used to refer to the proximate cause of death, which might differ from the cause that is used to classify the manner of death. For example, the proximate cause or mechanism of death might be brain ischemia (lack of blood flow to

1500-527: A traumatic incident such as in stress cardiomyopathy . Liability for a death classified as by natural causes may still be found if a proximate cause is established, as in the 1969 California case People v. Stamp . An unnatural cause of death results from an external cause, typically including homicides, suicides, accidents, medical errors , alcohol intoxications and drug overdoses . Jurisdictions differ in how they categorize and report unnatural deaths, including level of detail and whether they are considered

1575-410: Is a surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause, mode, and manner of death ; or the exam may be performed to evaluate any disease or injury that may be present for research or educational purposes. The term necropsy is generally used for non-human animals. Autopsies are usually performed by a specialized medical doctor called

1650-405: Is collected from the external surfaces of the body. Ultraviolet light may also be used to search body surfaces for any evidence not easily visible to the naked eye. Samples of hair , nails , and the like are taken, and the body may also be radiographically imaged . Once the external evidence is collected, the body is removed from the bag, undressed, and any wounds present are examined. The body

1725-552: Is complete, the body is reconstituted by sewing it back together. The term "autopsy" derives from the Ancient Greek αὐτοψία autopsia , "to see for oneself", derived from αὐτός ( autos , "oneself") and ὄψις ( opsis , "sight, view"). The word has been in use since around the 17th century. The term "post-mortem" derives from the Latin post , 'after', and mortem , 'death'. It was first recorded in 1734. The term "necropsy"

1800-595: Is derived from the Greek νεκρός 'death' and ὄψις ( opsis , 'sight, view'). The principal aims of an autopsy are to determine the cause of death , mode of death, manner of death , the state of health of the person before he or she died, and whether any medical diagnosis and treatment before death were appropriate. In most Western countries the number of autopsies performed in hospitals has been decreasing every year since 1955. Critics, including pathologist and former JAMA editor George D. Lundberg , have charged that

1875-596: Is evidence of a war crime , in which case troops on foreign territory might be prosecuted by the military justice system, domestic law enforcement, or the International Criminal Court . Some insurance contracts, such as life insurance policies , have special rules for certain manners of death. Suicide , for example, may invalidate claims under terms of such a contract. Autopsy An autopsy (also referred to as post-mortem examination , obduction , necropsy , or autopsia cadaverum )

1950-414: Is no need for any incision to be made, which will be visible after completion of the examination when the deceased is dressed in a shroud. In all of the above cases, the incision then extends all the way down to the pubic bone (making a deviation to either side of the navel) and avoiding, where possible, transecting any scars that may be present. Bleeding from the cuts is minimal, or non-existent because

2025-451: Is sometimes termed a "view and grant". The principle behind this is that the medical records, history of the deceased and circumstances of death have all indicated as to the cause and manner of death without the need for an internal examination. If not already in place, a plastic or rubber brick called a "head block" is placed under the shoulders of the corpse; hyperflexion of the neck makes the spine arch backward while stretching and pushing

2100-548: Is then cleaned, weighed, and measured in preparation for the internal examination. A general description of the body as regards ethnic group , sex , age, hair colour and length, eye colour , and other distinguishing features ( birthmarks , old scar tissue , moles , tattoos , etc.) is then made. A voice recorder or a standard examination form is normally used to record this information. In some countries, e.g. , Scotland, France, Germany, Russia, and Canada, an autopsy may comprise an external examination only. This concept

2175-413: Is used almost all of the time. The various organs are examined, weighed and tissue samples in the form of slices are taken. Even major blood vessels are cut open and inspected at this stage. Next, the stomach and intestinal contents are examined and weighed. This could be useful to find the cause and time of death, due to the natural passage of food through the bowel during digestion. The more area empty,

The powers of the legislature were expanded by the Government of Wales Act 2006 , which allows it to pass its own laws , and the Act also formally separated the Welsh Government from the Senedd. There is no equivalent body for England , which is directly governed by the parliament and government of the United Kingdom . During

At that time, most of the native inhabitants of Roman Britain spoke Brythonic languages , and were all regarded as Britons , divided into numerous tribes. After

2400-469: The afterlife (as with the Egyptians, who removed the organs through tiny slits in the body). Notable Greek autopsists were Erasistratus and Herophilus of Chalcedon , who lived in 3rd century BCE Alexandria , but in general, autopsies were rare in ancient Greece. In 44 BCE, Julius Caesar was the subject of an official autopsy after his murder by rival senators, the physician's report noting that

2475-476: The chest upward to make it easier to incise. This gives the APT, or pathologist, maximum exposure to the trunk . After this is done, the internal examination begins. The internal examination consists of inspecting the internal organs of the body by dissection for evidence of trauma or other indications of the cause of death. For the internal examination there are a number of different approaches available: There

Most pathologists, however, prefer the organs to be removed all in one "block". Using dissection of the fascia, blunt dissection; using the fingers or hands and traction; the organs are dissected out in one piece for further inspection and sampling. During autopsies of infants, this method

2625-417: The pulmonary artery is opened in order to search for a blood clot. The heart can then be removed by cutting the inferior vena cava, the pulmonary veins, the aorta and pulmonary artery, and the superior vena cava . This method leaves the aortic arch intact, which will make things easier for the embalmer. The left lung is then easily accessible and can be removed by cutting the bronchus , artery, and vein at

2700-652: The red dragon of Wales was dropped and replaced with the unicorn of Scotland with the succession of King James I who demoted Wales' status on the coat of arms and on the first adaptation of the Flag of Great Britain . Prior to 1746, it was not clear whether a reference to "England" in legislation included Wales, and so in 1746, Parliament passed the Wales and Berwick Act 1746 . This specified that in all prior and future laws, references to "England" would by default include Wales (and Berwick-upon-Tweed ). The Wales and Berwick Act

2775-443: The "Undetermined" category on the grounds that due to the fact-finder's lack of ability to examine the body, the examiner has no personal knowledge of the manner of (assumed) death; others classify such deaths in an additional category "Other", reserving "Undetermined" for deaths in which the fact-finder has access to the body, but the information provided by the body and examination of it is insufficient to provide sufficient grounds for

However, after the Norman invasion of Wales in the 11th century, English law came to apply in the parts of Wales conquered by the Normans (the Welsh Marches ). In 1283, the English, led by Edward I , with the biggest army brought together in England since the 11th century, conquered the remainder of Wales , then organised as the Principality of Wales . This

3000-665: The UK and worldwide has declined rapidly over the past 50 years. In the UK in 2013, only 0.7% of inpatient adult deaths were followed by consented autopsy. The autopsy rate in Germany is below 5% and thus much lower than in other countries in Europe. The governmental reimbursement is hardly sufficient to cover all the costs, so the medical journal Deutsches Ärzteblatt , issued by the German Medical Association , makes

3075-405: The UK is a modified version of this method, which is divided into four groups of organs. Although these are the two predominant evisceration techniques, in the UK variations on these are widespread. One method is described here: The pericardial sac is opened to view the heart. Blood for chemical analysis may be removed from the inferior vena cava or the pulmonary veins. Before removing the heart,

3150-501: The UK, following the Human Tissue Act 2004 all organs and tissue must be returned to the body unless permission is given by the family to retain any tissue for further investigation. Normally the internal body cavity is lined with cotton, wool, or a similar material, and the organs are then placed into a plastic bag to prevent leakage and are returned to the body cavity. The chest flaps are then closed and sewn back together and

3225-435: The ability to understand causes of death attributed unknown causes to "old age." With modern medicine and medical machinery , doctors are now able to learn more about how an elderly person may have died. Still, many doctors will refer to a cause of death as "old age" if it is more comforting for loved ones than providing specific details. There is particular ambiguity around the classification of cardiac deaths, triggered by

3300-460: The autopsy calculated that in about 25% of autopsies, a major diagnostic error will be revealed. However, this rate has decreased over time and the study projects that in a contemporary US institution, 8.4% to 24.4% of autopsies will detect major diagnostic errors. A large meta-analysis suggested that approximately one-third of death certificates are incorrect and that half of the autopsies performed produced findings that were not suspected before

3375-408: The autopsy is the reconstitution of the body such that it can be viewed, if desired, by relatives of the deceased following the procedure. After the examination, the body has an open and empty thoracic cavity with chest flaps open on both sides; the top of the skull is missing, and the skull flaps are pulled over the face and neck. It is unusual to examine the face, arms, hands or legs internally. In

3450-531: The body is called a diener , the German word for servant . In the UK this role is performed by an Anatomical Pathology Technician (APT), who will also assist the pathologist in eviscerating the body and reconstruction after the autopsy. After the body is received, it is first photographed . The examiner then notes the kind of clothes - if any - and their position on the body before they are removed. Next, any evidence such as residue, flakes of paint, or other material

3525-538: The body, by filling the veins with wax and metals. Until the 20th century, it was thought that the modern autopsy process derived from the anatomists of the Renaissance . Giovanni Battista Morgagni (1682–1771), celebrated as the father of anatomical pathology , wrote the first exhaustive work on pathology, De Sedibus et Causis Morborum per Anatomen Indagatis (The Seats and Causes of Diseases Investigated by Anatomy, 1769). In 1543, Andreas Vesalius conducted

3600-423: The brain is lifted out of the skull for further examination. If the brain needs to be preserved before being inspected, it is contained in a large container of formalin (15 percent solution of formaldehyde gas in buffered water ) for at least two, but preferably four weeks. This not only preserves the brain, but also makes it firmer, allowing easier handling without corrupting the tissue. An important component of

3675-403: The brain), caused by a malignant neoplasm ( cancer ), in turn caused by a dose of ionizing radiation administered by a person with intent to kill or injure, leading to certification of the manner of death as "homicide". The manner of death can be recorded as "undetermined" if there is not enough evidence to reach a firm conclusion. For example, the discovery of a partial human skeleton indicates

3750-759: The cause of death, but have also led to discoveries of various diseases such as fetal alcohol syndrome, Legionnaire's disease, and even viral hepatitis. Academic autopsies are performed by students of anatomy for the purpose of study, giving medical students and residents firsthand experience viewing anatomy and pathology. Postmortem examinations require the skill to connect anatomic and clinical pathology together since they involve organ systems and interruptions from ante-mortem and post-mortem. These academic autopsies allow for students to practice and develop skills in pathology and become meticulous in later case examinations. Virtual autopsies are performed using radiographic techniques which can be used in post-mortem examinations for

3825-423: The choices proscribed by the fact-finder's jurisdiction and will detail the evidence on the mechanism of the death. Clinical autopsies serve two major purposes. They are performed to gain more insight into pathological processes and determine what factors contributed to a patient's death. For example, material for infectious disease testing can be collected during an autopsy. Autopsies are also performed to ensure

3900-507: The circumstances of death were suspicious. International Classification of Disease codes are sometimes used to record manner and cause of death in a systematic way that makes it easy to compile statistics and feasible to compare events across jurisdictions. A natural cause of death occurs due to illness and its complications, or internal body malfunctions, and is not directly caused by external forces other than infectious diseases . Examples include pneumonia , diarrheal diseases , cancer ,

3975-638: The conquest, the Romans administered this region as a single unit, the province of Britain . Long after the departure of the Romans, the Britons in what became Wales developed their own system of law , first codified by Hywel Dda (Hywel the Good; reigned 942–950) when he was king of most of present-day Wales (compare King of Wales ); in England Anglo-Saxon law was initially codified by Alfred

4050-473: The coroner involve an autopsy but most do not involve a formal inquest . In England and Wales, a specific list of choices for verdicts is not mandated, and "narrative verdicts" are allowed, which are not specifically classified. The verdicts aggregated by the Ministry of Justice are: Some jurisdictions place deaths in absentia , such as deaths at sea and missing persons declared dead in a court of law, in

In the United States, autopsy rates fell from 17% in 1980 to 14% in 1985 and 11.5% in 1989, although the figures vary notably from county to county. The body is received at a medical examiner's office, municipal mortuary, or hospital in

4200-438: The end of the autopsy. At this stage, the organs are exposed. Usually, the organs are removed in a systematic fashion. Making a decision as to what order the organs are to be removed will depend highly on the case in question. Organs can be removed in several ways: The first is the en masse technique of Letulle whereby all the organs are removed as one large mass. The second is the en bloc method of Ghon. The most popular in

Autopsies that opened the body to determine the cause of death were attested at least in the early third millennium BCE, although they were opposed in many ancient societies where it was believed that the outward disfigurement of dead persons prevented them from entering

4350-515: The law applicable to that business entity. A registered office must be specified as "in Wales" if the company wishes to use a name ending cyfyngedig or cyf , rather than Limited or Ltd. or to avail itself of certain other privileges relating to the official use of the Welsh language. Outside the legal system, the position is mixed. Some organisations combine as "England and Wales", others are separate. The order of precedence in England and Wales

4425-536: The legal system of the Kingdom of England. This was in part to update outdated Welsh laws, but also to control Wales alongside England; through these acts, the Welsh could be seen as equals to the English. This was reflected on both Henry VIII and Elizabeth I 's coat of arms where the dragon represented Wales and the lion represented England. As soon as the Tudor dynasty ended with the death of Elizabeth I , however,

4500-400: The longer the deceased had gone without a meal before death. The body block that was used earlier to elevate the chest cavity is now used to elevate the head. To examine the brain , an incision is made from behind one ear, over the crown of the head, to a point behind the other ear. When the autopsy is completed, the incision can be neatly sewn up and is not noticed when the head is resting on

4575-486: The murder method, such as bullet wounds and exit points, signs of strangulation , or traces of poison . Some religions including Judaism and Islam usually discourage the performing of autopsies on their adherents. Organizations such as ZAKA in Israel and Misaskim in the United States generally guide families on how to ensure that an unnecessary autopsy is not made. Autopsies are used in clinical medicine to identify

4650-650: The need to consult Westminster. This was the first time in almost 500 years that Wales had its own powers to legislate. Each piece of Welsh legislation is known as an Act of Senedd Cymru . For a company to be incorporated in the United Kingdom, its application for registration with Companies House must state "whether the company's registered office is to be situated in England and Wales (or in Wales), in Scotland or in Northern Ireland", which will determine

4725-687: The person died. Also, it is thought that over one-fifth of unexpected findings can only be diagnosed histologically , i.e. , by biopsy or autopsy, and that approximately one-quarter of unexpected findings, or 5% of all findings, are major and can similarly only be diagnosed from tissue. One study found that (out of 694 diagnoses) "Autopsies revealed 171 missed diagnoses, including 21 cancers, 12 strokes, 11 myocardial infarctions, 10 pulmonary emboli, and 9 endocarditis, among others". Focusing on intubated patients, one study found "abdominal pathologic conditions – abscesses, bowel perforations, or infarction – were as frequent as pulmonary emboli as

In 2004 in England and Wales, there were 514,000 deaths, of which 225,500 were referred to the coroner . Of those, 115,800 (22.5% of all deaths) resulted in post-mortem examinations and there were 28,300 inquests , 570 with a jury. The rate of consented (hospital) autopsy in

4950-410: The reduction in autopsies is negatively affecting the care delivered in hospitals, because when mistakes result in death, they are often not investigated and lessons, therefore, remain unlearned. When a person has permitted an autopsy in advance of their death, autopsies may also be carried out for the purposes of teaching or medical research. An autopsy is usually performed in cases of sudden death, where

Medical examiners attempt to determine the time of death, the exact cause of death, and what, if anything, preceded the death, such as a struggle. A forensic autopsy may include obtaining biological specimens from the deceased for toxicological testing, including stomach contents. Toxicology tests may reveal the presence of one or more chemical "poisons" (all chemicals, in sufficient quantities , can be classified as

By around 150 BCE, ancient Roman legal practice had established clear parameters for autopsies. The greatest ancient anatomist was Galen (CE 129– c.  216 ), whose findings would not be challenged until the Renaissance over a thousand years later. Ibn Tufail has elaborated on autopsy in his treatise called Hayy ibn Yaqzan and Nadia Maftouni , discussing

Then the body may be wrapped in a shroud , and it is common for relatives to not be able to tell the procedure has been done when the body is viewed in a funeral parlor after embalming . An autopsy of stroke may be able to establish the time taken from the onset of cerebral infarction to the time of death. Various microscopic findings are present at times from infarction as follows: Around 3000 BCE, ancient Egyptians were one of

5250-457: The standard of care at hospitals. Autopsies can yield insight into how patient deaths can be prevented in the future. Within the United Kingdom, clinical autopsies can be carried out only with the consent of the family of the deceased person, as opposed to a medico-legal autopsy instructed by a Coroner (England & Wales) or Procurator Fiscal (Scotland), to which the family cannot object. Over time, autopsies have not only been able to determine

A PM 40 knife is used to remove the sternum from the soft tissue that attaches it to the mediastinum. Now the lungs and the heart are exposed. The sternum is set aside and will eventually be replaced at

The dissection of human remains for medical or scientific reasons continued to be practiced irregularly after the Romans, for instance by the Arab physicians Avenzoar and Ibn al-Nafis . In Europe they were done with enough regularity to become skilled, as early as 1200, and successful efforts to preserve

5475-407: The two Acts of Union, Parliament can restrict the effect of its laws to part of the realm, and generally the effect of laws, where restricted, was originally applied to one or more of the former kingdoms. Thus, most laws applicable to England also applied to Wales. However, Parliament now passes laws applicable to Wales and not to England (and vice versa), a practice which was rare before the middle of
