Health care is an increasingly diverse field where many specialties interact to provide patient care.
The team approach to caring for patients includes many professionals performing a variety of specialized functions designed to meet the physical, emotional and psychological needs of the patient. In the course of just one stay, a hospitalized patient may be cared for by an array of non-MD/DO providers.
For this collaborative approach to work, it is imperative that all health care professionals understand and respect the credentials, scope of practice and function of each member of the health care team.
So who are these providers? This article will provide a brief introduction to the educational background and role of the different professionals a patient might typically encounter in a hospital. This list is by no means inclusive but is meant to be an overview of the major groups of professional practitioners currently found in large, comprehensive hospitals.
The Nurse Practitioner
Nurse practitioners are licensed registered nurses who have completed advanced academic and supervised clinical training beyond their registered nurse certification. Most have masters degrees and many have doctoral degrees. Nurse practitioners provide a number of different health care services. They are trained to diagnose and treat a variety of conditions, and can order and interpret diagnostic tests and procedures, perform health screenings,give immunizations, and may prescribe most medications. Nurse practitioners often focus on health promotion, disease prevention and helping patients make healthy lifestyle choices. They treat patients in outpatient settings and in the hospital. Although most nurse practitioners focus on primary care, many train and practice in fields as diverse as OB/GYN, pediatrics, oncology and dermatology. An NP-C is a nurse practitioner who has successfully completed a national certification exam for adult and family nurse practitioners. Scope of practice and autonomy for nurse practitioners varies state by state with most states requiring nurse practitioners to complete a collaborative care agreement with a physician who provides an specified level of supervision and oversight.
The Doctor of Podiatric Medicine
Doctors of Podiatric Medicine (DPM’s) earn a bachelors degree and complete four years of podiatric medical school followed by a hospital-based residency. Podiatrists are represented in private practice, on hospital medical staffs, in health care administration, on medical school faculties and in the armed forces. Doctors of Podiatric Medicine are experts at preventing, diagnosing and treating diseases and disorders of the foot, ankle and related structures. DPM scope of practice varies by state but is generally restricted to the foot, ankle or sometimes other lower extremity structures. They provide medical, surgical and pharmacological treatments for a variety of foot conditions including diabetic foot care, sports injuries, wound care and congenital abnormalities. Most states allow DPMs to prescribe a full complement of medications used to treat conditions related to the foot and ankle.
The Clinical Nurse Specialist
Clinical nurse specialists are licensed registered nurses who have additional training in nursing at the masters or doctoral level. Clinical nurse specialists are experts in a specialized area of nursing practice such as geriatrics, wound care or psychiatric care. Many also work as administrators, educators, consultants or case managers. In addition to providing direct patient care, clinical nurse specialists may work to improve patient outcomes through research, training and bringing about improvements in health care delivery.
The Certified Registered Nurse Anesthetist
Certified Registered Nurse Anesthetists (CRNAs) are registered nurses who have a masters and advanced training in anesthesia. Their clinical and classroom training lasts for 24-36 months and all graduates must pass a national certification examination. CRNAs provide anesthetics to patients in every type of practice setting, and are the main anesthesia providers in two-thirds of all rural hospitals. They provide anesthesia in collaboration with other health care professionals such as surgeons, dentists, podiatrists and anesthesiologists. They utilize a variety of anesthesia techniques and procedures for all types of surgery and obstetrics. As with other nurse practitioners, requirements for physician supervision of CRNAs vary by state.

Recreation therapists work with clients of all ages and disease states.
Audiologists hold a master’s or doctoral degree from an accredited university-based graduate program. They can be found working in medical centers, hospitals, private practice, in schools and in government health facilities. Audiologists are primary care providers for hearing health. They evaluate hearing and balance problems using a variety of specialized auditory and vestibular assessments. Based upon the diagnosis, the audiologist can offer a patient a variety of treatment options including hearing aids. Audiologists are trained to manage hearing health for newborn through elderly patients. When a patient’s hearing or balance problems require medical or surgical evaluation or treatment, audiologists are trained to make referrals to physicians for intervention.
The Physician Assistant
Physician Assistants (or simply “PAs”) are licensed health care providers who typically possess a bachelor’s degree and have completed a 24-26 month PA training program. They work alongside physicians to perform physical examinations, diagnose and treat illnesses, order and interpret diagnostic tests, prescribe medication, and assist in surgery. PAs are found in virtually all medical specialties, ranging from Family Medicine to each of the surgical sub-specialties.
Pharmacists earn the Doctor of Pharmacy (PharmD) degree after completing at least two years of undergraduate study and four years of pharmacy school. Pharmacists are medication experts, working with physicians (or PAs) to ensure new prescriptions do not interact with a patient’s current medications, that the right dosage for a particular medication has been prescribed, and to answer any questions patients may have. Pharmacists employed within the Department of Veterans Affairs (VA) have the authority to prescribe and change medications under collaborative care agreements with patients’ physicians. Pharmacist prescriptive authority is becoming more widespread as the benefits of having pharmacists involved in disease state management become more apparent. Additionally, pharmacists can complete postgraduate residency training to become a Critical Care Pharmacist working in the ICU, an Emergency Pharmacist in the Emergency Department, or a number of other possible specialties.
