Forensic pathology

Duties

Forensic pathology is an application of medical jurisprudence. A forensic pathologist is a medical doctor who has completed training in anatomical pathology and has subsequently specialized in forensic pathology. The requirements for becoming a "fully qualified" forensic pathologist vary from country to country. Some of the different requirements are discussed below.

The forensic pathologist performs autopsies/postmortem examinations to determine the cause of death. The autopsy report contains an opinion about the following:

  • The pathological process, injury, or disease that directly results in or initiates a series of events that lead to a person's death (also called the mechanism of death), such as a bullet wound to the head, exsanguination caused by a stab wound, manual or ligature strangulation, myocardial infarction resulting from coronary artery disease, etc.)
  • The manner of death, the circumstances surrounding the cause of death, which, in most jurisdictions, include the following:[1]

The autopsy also provides an opportunity for other issues raised by the death to be addressed, such as the collection of trace evidence or determining the identity of the deceased.

The forensic pathologist examines and documents wounds and injuries, at autopsy, at the scene of a crime and occasionally in a clinical setting, such as rape investigation or deaths in custody.

Forensic pathologists collect and examine tissue specimens under the microscope (histology) to identify the presence or absence of natural disease and other microscopic findings such as asbestos bodies in the lungs or gunpowder particles around a gunshot wound.

They collect and interpret toxicological specimens of body tissues and fluids to determine the chemical cause of accidental overdoses or deliberate poisonings.

Forensic pathologists work closely with the medico-legal authority for the area concerned with the investigation of sudden and unexpected deaths: the coroner (England and Wales), procurator fiscal (Scotland), or coroner or medical examiner (United States).

They serve as expert witnesses in courts of law testifying in civil or criminal law cases.

In an autopsy, the forensic pathologist is often assisted by an autopsy/mortuary technician (sometimes called a diener in the US).

Forensic physicians, sometimes referred to as "forensic medical examiners" or "police surgeons" (in the UK until recently), are medical doctors trained in the examination of, and provision of medical treatment to, living victims of assault, including sexual assault, and individuals who find themselves in police custody. Many forensic physicians in the UK practice clinical forensic medicine part-time, and they also practice family medicine or another medical specialty.

In the United Kingdom, membership of the Royal College of Pathologists is not a prerequisite of appointment as a coroner's medical expert. Doctors in the UK who are not forensic pathologists or pathologists are allowed to perform medicolegal autopsies, as the wording of the Coroners and Justice Act 2009, which merely stipulates a "registered medical practitioner": anyone on the General Medical Council register.

Investigation of death
Main article: Coroner

Deaths where there is an unknown cause and those considered unnatural are investigated. In most jurisdictions this is done by a "forensic pathologist", coroner, medical examiner, or hybrid medical examiner-coroner offices.

Terminology is not consistent across jurisdictions

In some jurisdictions, the title of "Medical Examiner" is used by a non-physician, elected official involved in medicolegal death investigation. In others, the law requires the medical examiner to be a physician, pathologist, or forensic pathologist.

Similarly, the title "coroner" is applied to both physicians and non-physicians. Historically, coroners were not all physicians (most often serving primarily as the town mortician). However, in some jurisdictions the topic of "Coroner" is exclusively used by physicians.

Canadian coroners

In Canada, there was a mix of coroner and medical examiner systems, depending on the province or territory. In Ontario, coroners are licensed physicians, usually but not exclusively family physicians. In Quebec, there is a mix of medical and non-medical coroners, whereas in British Columbia, there is predominantly a non-physician coroner system. Alberta and Nova Scotia are examples of ME systems[2][3]

Coroners and medical examiners in the United States

In the United States, a coroner is typically an elected public official in a particular geographic jurisdiction who investigates and certifies deaths. The vast majority of coroners lack a Doctor of Medicine degree and the amount of medical training that they have received is highly variable, depending on their profession (e.g. law enforcement, judges, funeral directors, emergency medical technicians, nurses).

In contrast, a medical examiner is typically a physician who holds the degree of Doctor of Medicine or Doctor of Osteopathic Medicine. Ideally, a medical examiner has completed both a pathology residency and a fellowship in forensic pathology. In some jurisdictions, a medical examiner must be both a doctor and a lawyer, with additional training in forensic pathology.

History

In German-speaking Europe, lectures on forensic pathology were regularly held in Freiburg in the mid 18th century and Vienna in 1804. Scientists like Auguste Ambroise Tardieu, Johann Ludwig Casper and Carl Liman made great effort to develop forensic pathology into a science based on empirics.

Forensic pathology was first recognized in the United States by the American Board of Pathology in 1959.[4]

In Canada, it was formally recognized in 2003,[5][6] and a formal training program (a fellowship) is currently being established under the auspices of the Royal College of Physicians and Surgeons of Canada.[7]

Education

In most English speaking countries, forensic pathology is a subspecialty of anatomical pathology. Training requirements differ from country to country, however it is common for Pathologists to study at a medical school and go on to study pathology. Many Forensic Pathologists practice as a Histo (Hospital) Pathologist before moving onto Forensic Science

Australia

There are currently three paths to qualify as a forensic pathologist in Australia. The first is to train solely in forensic pathology (although a significant amount of anatomical pathology knowledge is still required) and pass two examinations for forensic pathology only. The second is to commence training in anatomical pathology, and complete an initial anatomical pathology examination, which takes a minimum of three years; then go on to train solely in forensic pathology and complete a forensic pathology examination, which takes a minimum of two years. The third is to complete a minimum 5 years' training in anatomical pathology to qualify as a fellow in anatomical pathology, then complete a post-fellowship year in forensic pathology (a minimum twelve months further training plus successful completion of an examination).[8]

Canada

In Canada,[9] anatomical pathology is a five-year residency. Residents who wish to become forensic pathologists must then complete a one-year fellowship in forensic pathology. Forensic pathology is a sub-specialty by the Royal College of Physicians and Surgeons. Three schools that have training programs are the University of Toronto, University of Alberta, and Mcmaster University.

India

In India, the speciality is commonly referred to as Forensic Medicine and Toxicology or Legal Medicine. After completion of medical graduation (MBBS), one has to complete three years of study and training including thesis research, which leads to award of degree of MD (Forensic Medicine). One can also alternately pass the board examination conducted by National Board of Examinations, leading to awarding of Diplomate of National Board (DNB).

The majority of the specialists are attached to the Department of Forensic Medicine and Toxicology in various medical colleges. The classification of posts includes Assistant Professor (Lecturer), Associate Professor (Reader) and Professor. The work profile of the specialists includes conducting autopsies and clinical forensic examinations; apart from teaching the medical students. They have to regularly appear in the courts as expert witnesses. A typical department in a government institution conducts 100 to 5,000 autopsies a year depending upon the jurisdiction. Apart from this the clinical forensic examinations constitute a major part of the work and number of cases can run up to ten thousand a year in an average institution.

The largest association of the specialty is Indian Academy of Forensic Medicine (IAFM), which also publishes its quarterly Journal of Indian Academy of Forensic Medicine regularly. This association has a specialist member strength of more than 1000.

Indonesia

In Indonesia, forensic medicine, also known as legal medicine ("kedokteran kehakiman"), is a 3-year specialty program that can be taken directly after completing medical school. It is separate from anatomical pathology and clinical pathology. Upon completion of the program, a forensic medicine specialist will obtain the title Spesialis Forensik, or Sp.F. He or she may be addressed in public as Dokter Forensik ("forensic doctor"). Note that there is no pre-medicine program, making the total duration of formal education for one to become a forensic specialist 9 years.

Forensic medicine is also a mandatory round during medical school clerkship. Medical students assist the doctors on autopsies, and they may also be allowed to perform an autopsy under supervision, and to witness in the court.

United Kingdom

In the UK, anatomical pathology is a five-year residency. Successful candidates are eligible for inclusion on the specialist register of the General Medical Council (GMC) having obtained Membership of the Royal College of Pathologists (United Kingdom).

A specialist training (ST) post is applied after the foundation year to enter a training program in Histopathology. Imminent changes as a result of the Tooke report may require two years or more to be fulfilled on general rotational placements before the option of histopathology arises. The Royal College has not yet issued their response to this matter. It is then necessary to obtain the MRCPath Part I examination in Histopathology, after which it is then possible to apply to one of few training posts in Forensic Pathology in the UK. Currently approved centres include Belfast, Liverpool, Leicester, Cardiff, London, Sheffield, Glasgow and Dundee. Not all the posts are currently actively training. Following 3 years of training in Forensic Pathology and completion of the FRCPath Part II slanted to Forensic Pathology, a candidate may then obtain CCT (certificate of completion of training) and work as a Consultant Forensic Pathologist. Another option is to obtain the full FRCPath in general histopathology, followed by another 18–24 months of training in forensic pathology, which will qualify the candidates with either the Diploma of the Royal College of Pathologists in Forensic Pathology (DipRCPath (forensic)) or the Diploma in Medical Jurisprudence (DMJ). In England and Wales, the candidate will also need to be Home Office Accredited, which will require checks of the training portfolio and completion of a security check and the Expert Witness Training Course run by the Forensic Science Service.

United States

In the United States, forensic pathologists typically complete at least one year of additional training (a fellowship) after completing an anatomical pathology residency and having passed the "board" examination administered by The American Board of Pathology or The American Osteopathic Board of Pathology ("board-certified"). Becoming an anatomic pathologist in the United States requires completing a residency in anatomic pathology, which is on-the-job training one must perform upon completing medical school before one may practice unsupervised. Anatomic pathology (as it is called) by itself is a three-year residency. Most U.S. pathologists complete a combined residency in both anatomic and clinical pathology, which requires a total of four years.

In the United States, all told, the education after high school is typically 13–15 years in duration (4 years undergraduate training + 4 years medical school + 4–5 years residency [anatomic and clinical pathology combined] + 1-2 year forensic pathology fellowship). Generally, the biggest hurdle is gaining admission to medical school, although the pass rate for anatomic and forensic pathology board examinations (in the U.S.) is approximately 80-90 and 90-100 percent, respectively. The courts do not require American Board of Pathology certification in order for a witness to be qualified as an expert in the field of forensic pathology, and there are several "diploma mills" that give online certificates in the field.[10]

Pathologists often feature in crime fiction. The following television series are listed alphabetically by the character's name:

  • Jordan Cavanaugh M.D., is a forensic pathologist in the Massachusetts Office of the Chief Medical Examiner, in the series Crossing Jordan'
  • Dr. Ravi Chakrabarti, Medical Examiner with the King County Medical Examiner's Office, in the series iZombie
  • Dr. Max Debryn, Home Office forensic pathologist in detective series Endeavour and Inspector Morse
  • Dr. Laura Hobson, pathologist and eventual love interest of D.I. Robbie Lewis in later episodes of 'Morse' and then for the entirety of the 'spin off' series 'Lewis'
  • Isabelle Lightwood, said to be the best forensic pathologist in New York the TV series, Shadowhunters
  • Sven Nyberg, Ystad police department's forensic pathologist in the Swedish, and British, series Wallander
  • Dr. Marco Pasquano, Vigàta's local forensic pathologist in the Italian series, Inspector Montalbano
  • Dr. R. Quincy, Chief medical examiner for Los Angeles County in the US TV series "Quincy, M.E."
  • Dr. Samantha Ryan, the primary character in the British drama series Silent Witness
  • Ambrose Spellman, coroner for the Spellman Sisters' Mortuary and main character in the Netflix supernatural horror series Chilling Adventures of Sabrina
gollark: ```go// detect if err isn't nil valueif err != nil { // if it isn't a nil value, make the function's return values be nil and the error in question return nil, err }```
gollark: Also, I'm semi-pointlessly asking again: anyone want an Ender Mailbox? I have them sort of half-working (needs fixes and lots of refactoring...). The idea is that you can send mail through ender chests to other people, somewhat securely and possibly automatically.
gollark: All shall be furnaces.
gollark: Alternatively, I'll just make it dump into every ender chest channel so it won't shut down until it makes about 440000.
gollark: Well, anyway, I assume you've shut it down, I'll implement safeguards against this eventually.
