Allied health professionals work in hospitals, clinics, and other settings
Allied health professionals are healthcare workers who are specially trained to prevent, diagnose, and treat diseases and disorders. They work alongside physicians and nurses, but are distinct from the fields of medicine, nursing, and dentistry. Allied health professionals make up a significant portion of the healthcare workforce worldwide, with estimates suggesting they comprise up to 60% of the US healthcare workforce.
Allied health professionals work in a variety of settings, including hospitals, clinics, and other facilities. In hospitals, they often work in teams alongside physicians and nurses, providing direct patient care and support. They may also work in administrative roles, performing tasks such as medical record-keeping and billing. Some allied health professionals are primarily based in hospitals, such as radiology technicians, ultrasound technicians, and medical sonographers, who use diagnostic machinery like X-ray machines and MRI scanners to help diagnose patients. Sterile processing professionals are also typically employed in hospitals, where they play a critical role in infection prevention by sterilizing, assembling, storing, and distributing medical instruments and supplies.
In clinics, allied health professionals may work in consultative positions, providing referrals and consultations. For example, physical and mental health therapists, nutritionists, and dietitians often have their own practices but maintain close ties with local clinics and hospitals. They may receive patient referrals from primary care health professionals and work indirectly with hospitals and clinics to provide patient care.
Allied health professionals also work in settings outside of traditional healthcare facilities. For instance, community health professionals help patients access healthcare services by acting as intermediaries between the community and health, social, or government systems. Exercise physiologists, who design fitness programs to aid patient recovery, may work in schools and health-related retail stores. Furthermore, advancements in medical technology have expanded the provision of care outside of hospitals, with an increasing number of services being delivered through ambulatory health care settings, such as doctors' offices, outpatient clinics, and mobile clinics. This shift towards ambulatory care is particularly notable in California, where the consumption of hospital days per person is predicted to decrease over time.

They provide diagnostic, preventive, therapeutic, and rehabilitative services
Allied health professionals (AHPs) provide diagnostic, preventive, therapeutic, and rehabilitative services. They are distinct from the fields of medicine, nursing, and dentistry. AHPs may work in the public or private sector, in hospitals or other facilities, and often in clinical collaboration with other providers with complementary scopes of practice.
AHPs provide diagnostic services to patients with certain illnesses. They work with technical and support staff to deliver direct patient care and diagnostics. Examples of diagnostic services provided by AHPs include radiologists, who use medical imaging technologies to diagnose and treat diseases.
In terms of preventive services, AHPs work to prevent disease transmission and improve health outcomes. This can include community health workers, who provide essential preventive services in ambulatory and community-based care settings.
Therapeutic services provided by AHPs include the treatment of patients with certain illnesses. Physiotherapists, for example, are considered AHPs and provide therapeutic services to help patients improve their physical movement and manage pain.
AHPs also provide rehabilitative services to help patients restore and maintain optimal physical, sensory, psychological, cognitive, and social functions. This can include helping patients regain physical strength and mobility after an injury or illness.

They are distinct from doctors, nurses, and dentists
Allied health professionals are distinct from doctors, nurses, and dentists in that they are not physicians, dentists, or nurses. They are a separate category of health professionals who provide diagnostic, preventive, therapeutic, and rehabilitative services. Allied health professionals work with physicians and nurses to treat patients, but they are not the same as doctors, nurses, or dentists.
Allied health professionals include a wide range of roles such as dental hygienists, nutrition supervisors, pharmacists, community health workers, and healthcare technicians. They may also include administrative professionals who perform duties such as billing and managing records. In addition, allied health professionals can include diagnostic professionals who use machinery like X-ray and MRI machines to help diagnose patients. These professionals often have specific training on the machinery they use.
While doctors, nurses, and dentists typically receive a formal education in medicine, nursing, or dentistry, allied health professionals may have varying levels of education and training. Some allied health professionals, such as technicians and aides, may be trained on the job or through short vocational programs. Others, such as medical record technicians, may hold an associate degree, while others, such as medical record administrators, may have a bachelor's degree.
Allied health professionals are also distinct from doctors, nurses, and dentists in that they often work outside of traditional hospital settings. In the US, a large proportion of the allied health workforce is employed in ambulatory settings or nursing care facilities. With advancements in medical technology, many services that once required hospital stays can now be provided through ambulatory care. This shift towards ambulatory and community-based care is also seen in developing countries, where there is a focus on scaling up the training of allied health professionals to provide essential preventive and treatment services outside of hospitals.
Furthermore, while doctors, nurses, and dentists typically have clearly defined roles and responsibilities, the roles within allied health can vary widely. Allied health professionals may work in direct patient care roles or in supportive roles. They may have indirect contact with patients or work behind the scenes in areas such as pharmacy or laboratory science. The diversity of roles within allied health allows professionals to choose between careers with direct patient interaction or those that are more focused on administrative tasks or health systems management.
