Medical practitioner in the context of "Luke Fildes"

A death certificate is either a legal document issued by a medical practitioner which states when a person died, or a document issued by a government civil registration office, that declares the date, location and cause of a person's death, as entered in an official register of deaths.

An official death certificate is usually required to be provided when applying for probate or administration of a deceased estate. They are also sought for genealogical research. The government registration office would usually be required to provide details of deaths, without production of a death certificate, to enable government agencies to update their records, such as electoral registers, government benefits paid, passport records, transfer the inheritance, etc.

In the United Kingdom, a resident doctor, known until 2024 as a junior doctor, is a qualified medical practitioner who is either engaged in postgraduate training or employed in a non-training post. The period of being a resident doctor starts when they qualify as a medical practitioner following graduation with a Bachelor of Medicine, Bachelor of Surgery degree and start the UK Foundation Programme. It culminates in a post as a consultant, a general practitioner (GP), or becoming a SAS doctor (Specialty, Associate Specialist, or Specialist doctor).

The term resident doctor currently incorporates the grades of foundation doctor, core trainee (in some specialties, such as surgery, medicine, and psychiatry), and specialty registrar. Before 2007, it included the grades of pre-registration house officer, senior house officer and specialist registrar. During this time, resident doctors will do postgraduate examinations to become members of a medical royal college relevant to the specialty in which they are training, for example membership of the Royal College of Physicians for doctors specialising in internal medicine, membership of the Royal College of Surgeons for doctors specialising in surgery or membership of the Royal College of General Practitioners for doctors specialising in family medicine. Doctors typically may be resident doctors for 8–20 years, and this may be extended by doing research towards a higher degree, for example a Doctor of Philosophy or Doctor of Medicine degree. In England, there are around 71,000 resident doctors.

An intensivist, also known as a critical care doctor, is a medical practitioner who specializes in the care of critically ill patients, most often in the intensive care unit (ICU). Intensivists can be internists or internal medicine sub-specialists (most often pulmonologists), anaesthesiologists, emergency medicine physicians, paediatricians (including neonatologists), or surgeons who have completed a fellowship in critical care medicine. The intensivist must be competent not only in a broad spectrum of conditions among critically ill patients but also with the technical procedures and equipment used in the intensive care setting such as airway management, rapid sequence induction of anaesthesia, maintenance and weaning of sedation, central venous and arterial catheterisation, point of care ultrasound, renal replacement therapy and management of mechanical ventilators.
