Occupational therapist in the context of "Health professional"

A psychiatrist is a physician who specializes in psychiatry. Psychiatrists are physicians who evaluate patients to determine whether their symptoms are the result of a physical illness, a combination of physical and mental ailments or strictly mental issues. Sometimes a psychiatrist works within a multi-disciplinary team, which may comprise clinical psychologists, social workers, occupational therapists, and nursing staff. Psychiatrists have broad training in a biopsychosocial approach to the assessment and management of mental illness.

As part of the clinical assessment process, psychiatrists may employ a mental status examination; a physical examination; brain imaging such as a computerized tomography, magnetic resonance imaging, or positron emission tomography scan; and blood testing. Psychiatrists use pharmacologic, psychotherapeutic, or interventional approaches to treat mental disorders.

A clinician is a health care professional typically employed at a skilled nursing facility or clinic. Clinicians work directly with patients rather than in a laboratory, community health setting or in research. A clinician may diagnose, treat and care for patients as a psychologist, clinical pharmacist, clinical scientist, nurse, occupational therapist, speech-language pathologist, physiotherapist, dentist, optometrist, physician assistant, clinical officer, physician, paramedic, or chaplain. Clinicians undergo and take comprehensive training and exams to be licensed and some complete graduate degrees (master's or doctorates) in their field of expertise.

The main function of a clinician is to manage a sick person in order to cure their illness, reduce pain and suffering, and extend life considering the impact of illness upon the patient and their family as well as other social factors.

Preoperative rehabilitation, prehabilitation or prehab, is a form of healthcare intervention that takes place before a medical or surgical intervention with the aim to reduce side effects and complications, and enhance recovery. Multidisciplinary team involvement can range from physiotherapists, occupational therapists, respiratory therapists, doctors, pharmacologists, anesthesiologists, psychologists, psychiatrists and sports physiologists.

Prehab can be applied to surgical populations in oncology, cardiorespiratory, cardiovascular and orthopaedic settings. The intention is that increasing baseline fitness prior to surgery will allow for relatively higher fitness post-operatively. Prehabilitation interventions are tailored to the patient so that even those with high amounts of comorbidities can receive a positive outcome. Research evidence is mixed, but suggests that prehabilitation reduces hospital stays and therefore risk of hospital acquired infections such as pneumonia.
