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.[1]
To a certain extent, medical practitioners have long been specialized. According to Galen, specialization was common among Roman physicians.[citation needed] The particular system of modern medical specialties evolved gradually during the 19th century. Informal social recognition of medical specialization evolved before the formal legal system. The particular subdivision of the practice of medicine into various specialties varies from country to country, and is somewhat arbitrary.[2]
Classification of medical specialization
Medical specialties can be classified along several axes. These are:
Surgical or internal medicine
Age range of patients
Diagnostic or therapeutic
Organ-based or technique-based
Throughout history, the most important has been the division into surgical and internal medicine specialties. The surgical specialties are those in which an important part of diagnosis and treatment 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 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 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.
List of specialties recognized in the European Union and European Economic Area
The European Union publishes a list of specialties recognized in the European Union, and by extension, the European Economic Area.[3] 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.
Continuing, comprehensive healthcare for the individual and family, integrating the biological, clinical and behavioral sciences to treat patients of all ages, sexes, organ systems, and diseases.
A relatively modern branch of clinical medicine that deals with pain and symptom relief and emotional support in patients with terminal illnesses including cancer and heart failure.
Understanding disease through examination of molecules, cells, tissues and organs. The term encompasses both the medical specialty that uses tissues and body fluids to obtain clinically useful information and the related scientific study of disease processes.
Child and adolescent psychiatry focuses on the care of children and adolescents with mental, emotional, and learning problems including ADHD, autism, and family conflicts.
Public health focuses on the health of populations. Physicians employed in this field work in policy, research or health promotion, taking a broad view of health that encompasses the social determinants of health.
Interventional radiology is concerned with using expert imaging of the human body, usually via CT, ultrasound, fluoroscopy, or MRI to perform a breadth of intravascular procedures (angioplasty, arterial stenting, thrombolysis, uterine fibroid embolization), biopsies and minimally invasive oncologic procedures (radiofrequency and cryoablation of tumors & transarterial chemoembolization)
Nuclear medicine uses radioactive substances for in vivo and in vitro diagnosis either using imaging of the location of radioactive substances placed into a patient or using in vitro diagnostic tests utilizing radioactive substances.
The use of expertise in radiation in the context of medical imaging for diagnosis or image guided minimally invasive therapy. X-rays, etc.
According to the 2022 Medscape Physician Compensation Report, physicians on average earn $339K annually. Primary care physicians earn $260K annually while specialists earned $368K annually.[6]
The table below details the average range of salaries for physicians in the US of medical specialties:[6][7]
There are 15 recognised specialty medical Colleges in Australia.[8][9][10] The majority of these are Australasian Colleges and therefore also oversee New Zealand specialist doctors. These Colleges are:
Addiction medicine, Adolescent and young adult medicine, Cardiology, Clinical Genetics, Clinical haematology, Clinical pharmacology, Community child health, Endocrinology, Gastroenterology, General and acute care medicine, General paediatrics Geriatric medicine, Haematology, Infectious diseases, Immunology and allergy, Neonatal and perinatal medicine, Nephrology, Neurology, Nuclear medicine, Occupational medicine, Oncology, Paediatric emergency medicine, Palliative medicine, Public health, Rehabilitation, Respiratory and sleep medicine, Rheumatology, Sexual Health
There are some collegiate bodies in Australia that are not officially recognised as specialties by the Australian Medical Council but have a college structure for members, such as: Australasian College of Physical Medicine
There are some collegiate bodies in Australia of Allied Health non-medical practitioners with specialisation. They are not recognised as medical specialists, but can be treated as such by private health insurers, such as: Australasian College of Podiatric Surgeons
In Sweden, a medical license is required before commencing specialty training. Those graduating from Swedish medical schools are first required to do a rotational internship of about 1.5 to 2 years in various specialties before attaining a medical license. The specialist training lasts 5 years.[12]
All boards of certification now require that medical practitioners demonstrate, by examination, continuing mastery of the core knowledge and skills for a chosen specialty. Recertification varies by particular specialty between every seven and every ten years.
In the United States there are hierarchies of medical specialties in the cities of a region. Small towns and cities have primary care, middle sized cities offer secondary care, and metropolitan cities have tertiary care. Income, size of population, population demographics, distance to the doctor, all influence the numbers and kinds of specialists and physicians located in a city.[13]
Demography
A population's income level determines whether sufficient physicians can practice in an area and whether public subsidy is needed to maintain the health of the population. Developing countries and poor areas usually have shortages of physicians and specialties, and those in practice usually locate in larger cities. For some underlying theory regarding physician location, see central place theory.[13]
The proportion of men and women in different medical specialties varies greatly.[14] Such sex segregation is largely due to differential application.[15]
Satisfaction and burnout
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.[16] In contrast, primary care physicians were the least satisfied, followed by nephrologists, obstetricians/gynecologists, and pulmonologists.[16] 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.[17][18] 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.[19]
Occupational medicine – branch of clinical medicine that provides health advice to organizations and individuals concerning work-related health and safety issues and standards. See occupational safety and health.
Preventive medicine – part of medicine engaged with preventing disease rather than curing it. It can be contrasted not only with curative medicine, but also with public health methods (which work at the level of population health rather than individual health).
Medicine is the science and practice of caring for patients, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
A physician, medical practitioner, medical doctor, or simply doctor is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases, and their treatment, which is the science of medicine, and a decent competence in its applied practice, which is the art or craft of the profession.
Emergency medicine is the medical specialty concerned with the care of illnesses or injuries requiring immediate medical attention. Emergency medicine physicians specialize in providing care for unscheduled and undifferentiated patients of all ages. As first-line providers, in coordination with emergency medical services, they are primarily responsible for initiating resuscitation and stabilization and performing the initial investigations and interventions necessary to diagnose and treat illnesses or injuries in the acute phase. Emergency medical physicians generally practice in hospital emergency departments, pre-hospital settings via emergency medical services, and intensive care units. Still, they may also work in primary care settings such as urgent care clinics.
A general practitioner (GP) or family physician is a doctor who is a consultant in general practice.
Internal medicine, also known as general internal medicine in Commonwealth nations, is a medical specialty for medical doctors focused on the prevention, diagnosis, and treatment of internal diseases in adults. Medical practitioners of internal medicine are referred to as internists, or physicians in Commonwealth nations. Internists possess specialized skills in managing patients with undifferentiated or multi-system disease processes. They provide care to both hospitalized (inpatient) and ambulatory (outpatient) patients and often contribute significantly to teaching and research. Internists are qualified physicians who have undergone postgraduate training in internal medicine, and should not be confused with "interns", a term commonly used for a medical doctor who has obtained a medical degree but does not yet have a license to practice medicine unsupervised.
A dentist, also known as a dental surgeon, is a health care professional who specializes in dentistry, the branch of medicine focused on the teeth, gums, and mouth. The dentist's supporting team aids in providing oral health services. The dental team includes dental assistants, dental hygienists, dental technicians, and sometimes dental therapists.
A podiatrist is a medical professional devoted to the treatment of disorders of the foot, ankle, and related structures of the leg. The term originated in North America but has now become the accepted term in the English-speaking world for all practitioners of podiatric medicine. The word chiropodist was previously used in the United States, but it is now regarded as antiquated.
Podiatry, or podiatric medicine and surgery, is a branch of medicine devoted to the study, diagnosis, and treatment of disorders of the foot, ankle and lower limb. The healthcare professional is known as a podiatrist. The US podiatric medical school curriculum includes lower extremity anatomy, general human anatomy, physiology, general medicine, physical assessment, biochemistry, neurobiology, pathophysiology, genetics and embryology, microbiology, histology, pharmacology, women's health, physical rehabilitation, sports medicine, research, ethics and jurisprudence, biomechanics, general principles of orthopedic surgery, plastic surgery, and foot and ankle surgery.
Residency or postgraduate training is a stage of graduate medical education. It refers to a qualified physician, veterinarian, dentist, podiatrist (DPM) or pharmacist (PharmD) who practices medicine or surgery, veterinary medicine, dentistry, podiatry, or clinical pharmacy, respectively, usually in a hospital or clinic, under the direct or indirect supervision of a senior medical clinician registered in that specialty such as an attending physician or consultant.
The Royal Australian and New Zealand College of Radiologists (RANZCR) is the leading professional organisation for the promotion of the science and practice of the medical specialties of clinical radiology and radiation oncology in Australia and New Zealand. The college has members throughout the world. RANZCR provides the educational curricula for medical graduates training to enter the specialties.
A number of professional degrees in dentistry are offered by dental schools in various countries around the world.
Medical education in Australia includes the educational activities involved in the initial and ongoing training of Medical Practitioners. In Australia, medical education begins in Medical School; upon graduation it is followed by a period of pre-vocational training including Internship and Residency; thereafter, enrolment into a specialist-vocational training program as a Registrar eventually leads to fellowship qualification and recognition as a fully qualified Specialist Medical Practitioner. Medical education in Australia is facilitated by Medical Schools and the Medical Specialty Colleges, and is regulated by the Australian Medical Council (AMC) and Australian Health Practitioner Regulation Agency (AHPRA) of which includes the Medical Board of Australia where medical practitioners are registered nationally.
A medicalintern is a physician in training who has completed medical school and has a medical degree, but does not yet have a license to practice medicine unsupervised. Medical education generally ends with a period of practical training similar to internship, but the way the overall program of academic and practical medical training is structured differs depending upon the country, as does the terminology used.
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, anaesthesiologists, emergency medicine physicians, paediatricians, 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, renal replacement therapy and management of mechanical ventilators.
The Royal Australasian College of Surgeons (RACS) is the leading advocate for surgical standards, professionalism and surgical education in Australia and New Zealand.
A clinical officer (CO) is a gazetted officer who is qualified and licensed to practice medicine.
Phlebology is a medical speciality that is concerned with venous issues including the diagnosis and treatment of disorders of the veins. A medical specialist in this field is known as a phlebologist. The specialty of phlebology has developed to enable physicians sharing an interest in venous disease and health to share knowledge and experience despite being trained in a variety of backgrounds such as dermatology, vascular surgery, haematology, interventional radiology or general medicine. Diagnostic techniques used include the patient's history and physical examination, venous imaging techniques in particular vascular ultrasound and laboratory evaluation related to venous thromboembolism. The American Medical Association and the American Osteopathic Association have added phlebology to their list of self-designated practice specialties.
In the United States and Canada, there are twelve recognized dental specialties in which some dentists choose to train and practice, in addition to or instead of general dentistry. In the United Kingdom and Australia, there are thirteen.
The University of Tennessee College of Medicine is one of six graduate schools of the University of Tennessee Health Science Center (UTHSC) in downtown Memphis. The oldest public medical school in Tennessee, the UT College of Medicine is a LCME-accredited member of the Association of American Medical Colleges (AAMC) and awards graduates of the four-year program Doctor of Medicine (MD) degrees. The college's primary focus is to provide practicing health professionals for the state of Tennessee.
