Allied health professions (AHPs) are a category of health professionals that provide a range of diagnostic, preventive, therapeutic, and rehabilitative services in connection with health care. While there is no international standard for defining the diversity of allied health professions, they are typically considered those which are distinct from the fields of medicine, nursing and dentistry. [1] [2]
In providing care to patients with certain illnesses, AHPs may work in the public or private sector, in hospitals or in other types of facilities, and often in clinical collaboration with other providers having complementary scopes of practice. Allied health professions are usually of smaller size proportional to physicians and nurses. It has been estimated that approximately 30% of the total health workforce worldwide are AHPs. [3]
In most jurisdictions, AHPs are subject to health professional requisites including minimum standards for education, regulation and licensing. They must work based on scientific principles and within an evidence based practice model. [3] They may sometimes be considered to perform the role of mid-level practitioners, when having an advanced education and training to diagnose and treat patients, but not the certification of a physician. Allied health professionals are different from alternative medicine practitioners, also sometimes called natural healers, who work outside the conventions of modern biomedicine.
The organization of International Chief Health Professions Officers (ICHPO) [3] developed a widely-used definition of the allied health professions:
Allied Health Professions are a distinct group of health professionals who apply their expertise to prevent disease transmission, diagnose, treat and rehabilitate people of all ages and all specialties. Together with a range of technical and support staff they may deliver direct patient care, rehabilitation, treatment, diagnostics and health improvement interventions to restore and maintain optimal physical, sensory, psychological, cognitive and social functions. [4]
The allied health professions represent a large cluster of health and care service providers, which usually require specific training and/or certification, but which are distinct from the medicine, nursing and dentistry professions. [1] There is a large demand for allied health professionals, especially in rural and medically underserved areas. [2] AHPs are generally considered distinct from other healthcare service providers on the basis of several factors. These factors may include AHPs offering services in ways which support treatments provided by other healthcare professionals (working either in independent autonomous practice or under direct supervision), or by offering services which other healthcare professionals require but do not provide themselves (for example in the use of medical technologies). [5]
The precise titles, roles and requisites of AHPs vary considerably from country to country. For the United States, a generic definition is in the Public Health Service Act, including those with "training, in a science relating to health care, [and] who shares in the responsibility for the delivery of health care services or related services" (other than a registered nurse or physician assistant). [6] In South Africa, AHPs are identified and regulated through the Health Professions Council of South Africa (e.g., clinical technologists, dental therapists) or through the Allied Health Professions Council (e.g., massage therapists, chiropractors). [7]
Depending on the country and local health care system, the professions that are considered AHPs vary. For example, in some contexts optometrists are not considered AHPs, as the profession has a longer history of primary care practice independent of modern medicine, [8] whereas in others optometrists are identified as falling under the AHP umbrella. [9] [10] Similarly, in some health care jurisdictions physiotherapists are not considered AHPs, as they tend to have more autonomy in private practice without the need for medical referral, [5] whereas in other jurisdictions physiotherapists are identified and regulated as AHPs. [11] [12]
A limited subset of the following professional areas may be represented, and may be regulated:
Some allied health professions are more specialized, and so must adhere to national training and education standards and their professional scope of practice. Often they must prove their skills through degrees, diplomas, certified credentials, and continuing education. Other allied health professions require no special training or credentials and are trained for their work by their employer through on-the-job training (which would then exclude them from consideration as an allied health profession in a country like Australia). Many allied health jobs are considered career ladder jobs because of the opportunities for advancement within specific fields. [14]
Allied health professions can include the use of many skills. Depending on the profession, these may include basic life support; medical terminology, acronyms and spelling; basics of medical law and ethics; understanding of human relations; interpersonal communication skills; counseling skills; computer literacy; ability to document healthcare information; interviewing skills; and proficiency in word processing; database management and electronic dictation. [15]
The explosion of scientific knowledge that followed World War II brought increasingly sophisticated and complex medical diagnostic and treatment procedures. Increasing public demand for medical services combined with higher health care costs provoked a trend toward expansion of service delivery from treating patients in hospitals to widespread provision of care in physician's private and group practices, ambulatory medical and emergency clinics, and mobile clinics and community-based care.
Changes in the health industry and emphasis on cost-efficient solutions to health care delivery will continue to encourage expansion of the allied health workforce. The World Health Organization estimates there is currently a worldwide shortage of about 2 million allied health professionals (considering all health workers aside from medical and nursing personnel) needed in order to meet global health goals. [16]
In recognition of the growth of the number and diversity of allied health professionals in recent years, the 2008 version of the International Standard Classification of Occupations increased the number of groups dedicated to allied health professions. Depending on the presumed skill level, they may either be identified as "health professionals" or "health associate professionals". For example, new categories have been created for delineating "paramedical practitioners"—grouping professions such as clinical officers, clinical associates, physician assistants, Feldshers, and assistant medical officers—as well as for community health workers; dietitians and nutritionists; audiologists and speech therapists; and others. [17]
In developing countries, many national human resources for health strategic plans and international development initiatives are focusing on scaling up training of allied health professions, such as HIV/AIDS counsellors, clinical officers and community health workers, in providing essential preventive and treatment services in ambulatory and community-based care settings. [18]
With growing demand for ambulatory health care, researchers expect to witness a heavier demand for professions that are employed outside of hospital settings — including allied health. [19]
In India, the National Commission for Allied and Healthcare Professions identifies and sets quality standards for 56 professions in diagnostics, therapeutics, community health, and biomedical technology (e.g., physiotherapists, radiologists). [20]
In the United Kingdom there are 12 distinct professions who are considered allied health professionals; in combination they account for about 6% of the NHS workforce. In 2013 the annual expenditure on services provided by allied health professionals amounted to around £2 billion, although there is a lack of evidence around the extent to which these services improve the quality of care. [21]
In the United States, the Association of Schools of Allied Health Professionals [22] uses wording from the Public Health Service Act to list those who are considered to be allied health professionals. [6]
Professionals who are excluded under the Act from the list of AHPs, although they may possess degrees or diplomas in health sciences, include the following:
Projections in the United States and many other countries have shown an expected long-term shortage of qualified workers to fill many allied health positions. This is primarily due to expansion of the health industry due to demographic changes (a growing and aging population), large numbers of health workers nearing retirement, the industry's need to be cost efficient, and a lack of sufficient investment in training programs to keep pace with these trends. [23] [24]
Studies have also pointed to the need for increased diversity in the allied health workforce to realize a culturally competent health system. [25]
Workforce and health care experts anticipate that health services will increasingly be delivered via ambulatory and nursing care settings rather than in hospitals. According to the North American Industry Classification System (NAICS), the health care industry consists of four main sub-sectors, divided by the types of services provided at each facility: [26]
In the US, a larger proportion of the allied health care workforce is already employed in ambulatory settings. In California, nearly half (49.4 percent) of the allied health workforce is employed in ambulatory health care settings, compared with 28.7 percent and 21.9 percent employed in hospital and nursing care, respectively. [19] One source reported allied health professionals making up 60 percent of the total US health workforce. [27] Advancements in medical technology also allow for more services that formerly required expensive hospital stays to be delivered via ambulatory care. For example, in California, research has predicted the total consumption of hospital days per person will decline from 4 days in 2010 to 3.2 days in 2020 to 2.5 days in 2030. In contrast, the number of ambulatory visits per person will increase from 3.2 visits per person in 2010 to 3.6 visits per person in 2020 to 4.2 visits in 2030. [19]
Physical therapy (PT), also known as physiotherapy, is a healthcare profession, as well as the care provided by physical therapists who promote, maintain, or restore health through patient education, physical intervention, disease prevention, and health promotion. Physical therapist is the term used for such professionals in the United States, and physiotherapist is the term used in many other countries.
A respiratory therapist is a specialized healthcare practitioner trained in critical care and cardio-pulmonary medicine in order to work therapeutically with people who have acute critical conditions, cardiac and pulmonary disease. Respiratory therapists graduate from a college or university with a degree in respiratory therapy and have passed a national board certifying examination. The NBRC is responsible for credentialing as a CRT, or RRT in the United States. The CBRC is responsible for credentialing as an RRT in Canada.
Health care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care. The term includes work done in providing primary care, secondary care, tertiary care, and public health.
Ambulatory care or outpatient care is medical care provided on an outpatient basis, including diagnosis, observation, consultation, treatment, intervention, and rehabilitation services. This care can include advanced medical technology and procedures even when provided outside of hospitals.
A physician assistant or physician associate (PA) is a type of healthcare professional. While these job titles are used internationally, there is significant variation in training and scope of practice from country to country, and sometimes between smaller jurisdictions such as states or provinces. Depending on location, PAs practice semi-autonomously under the supervision of a physician, or autonomously perform a subset of medical services classically provided by physicians.
A surgical technologist, also called a scrub, scrub tech, surgical technician, or operating department practitioner or operating room technician, is an allied health professional working as a part of the team delivering surgical care. Surgical technologists are members of the surgical team. The members of the team include the surgeon, surgeon's assistant, circulator nurse and anesthesia provider. They possess knowledge and skills in sterile and aseptic techniques. There are few mandatory professional requirements for surgical technologists, and the scope of practice varies widely across countries and jurisdictions. Surgical technologists attend junior colleges and technical schools, and many are trained in military schools. In the military they perform the duties of both the circulator and the scrub. The goal is for surgical technologists to be able to anticipate the next move the surgeon is going to make in order to make the procedure as smooth and efficient as possible. They do this by having knowledge of hundreds of surgical procedures and the steps the surgeon needs to take in order to complete the procedure, including the very wide range of surgical instruments they may need. Specialties can include, but are not limited to, the following: genitourinary, obstetrics and gynaecology, urology, ENT, plastics, general, orthopedics, neurology, and cardiovascular. They only work in surgical or perioperative areas and are highly specialized. Surgical technologist is the proper term for a two-year program which earns a degree in applied sciences. The profession is up and coming and highly in demand.

The Health and Care Professions Council (HCPC), formerly the Health Professions Council (HPC), is a statutory regulator of over 280,000 professionals from 15 health and care professions in the United Kingdom. The Council reports its main purpose is to protect the public. It does this by setting and maintaining standards of proficiency and conduct for the professions it regulates. Its key functions include approving education and training programmes which health and care professionals must complete before they can register with the HCPC; and maintaining and publishing a Register of health and care providers who meet predetermined professional requirements and standards of practice.
A health professional, healthcare professional, or healthcare worker is a provider of health care treatment and advice based on formal training and experience. The field includes those who work as a nurse, physician, physician assistant, registered dietitian, veterinarian, veterinary technician, optometrist, pharmacist, pharmacy technician, medical assistant, physical therapist, occupational therapist, dentist, midwife, psychologist, audiologist, or healthcare scientist, or who perform services in allied health professions. Experts in public health and community health are also health professionals.
HealthForceOntario was a collaborative initiative, announced May 3, 2006, involving two Ontario Canada ministries: Ministry of Health and Long-Term Care (Ontario) and the Ministry of Training, Colleges and Universities. It was subsequently subsumed under Ontario Health in 2019.
Mid-level practitioners, also called non-physician practitioners, advanced practice providers, or commonly mid-levels, are health care providers who assess, diagnose, and treat patients but do not have formal education or certification as a physician. The scope of a mid-level practitioner varies greatly among countries and even among individual practitioners. Some mid-level practitioners work under the close supervision of a physician, while others function independently and have a scope of practice difficult to distinguish from a physician. The legal scope of practice for mid-level practitioners varies greatly among jurisdictions, with some having a restricted and well-defined scope, while others have a scope similar to that of a physician. Likewise, the training requirement for mid-level practitioners varies greatly between and within different certifications and licensures.
A clinical officer (CO) is a gazetted officer who is qualified and licensed to practice medicine.
Clinical clerkships encompass a period of medical education in which students – medical, dental, veterinary, nursing or otherwise – practice medicine under the supervision of a health practitioner.
Health professional requisites refer to the regulations used by countries to control the quality of health workers practicing in their jurisdictions and to control the size of the health labour market. They include licensure, certification and proof of minimum training for regulated health professions.
The Mayo Clinic School of Health Sciences is an accredited, private, nonprofit school of higher education specializing in allied health education. MCSHS operates within the Mayo Clinic College of Medicine and Science, which is the educational division of Mayo Clinic. As such, MCSHS is fully integrated with Mayo Clinic hospitals and clinics.
The Health Sciences University Foundation is a private educational and health care university founded in 1976. It has two locations: the main hospital and one in the University Children's Hospital, San José, Bogotá, Colombia. It offers seven undergraduate programs: Business Administration, Nursing, Surgical technologist, Medicine, Psychology with clinical emphasis, Emergency medical technician (EMT) and Cytology.
Healthcare professional credentials are credentials awarded to many healthcare practitioners as a way to standardize the level of education and ability to provide care.
The Bureau of Health Workforce is a part of the Health Resources and Services Administration (HRSA), of the United States Department of Health and Human Services. HRSA programs train health care professionals and place them where they are needed most. Grants support scholarship and loan repayment programs at colleges and universities to meet critical workforce shortages and promote diversity within the health professions.
The National Commission for Allied and Healthcare Professions (NCAHP) is the Indian regulatory body for allied and healthcare professionals (AHP). It covers all AHP who were not covered under National Medical Commission, Dental Council of India, Indian Nursing Council, Pharmacy Council of India etc till 2021 and groups all into ten categories with power to regulate education and professionals of all ten categories.
