Healthcare Assistant and Healthcare Science

Nature of the Work

Combining medical technology and the human touch, the healthcare industry diagnoses, treats, and administers care around the clock, responding to the needs of millions of people-from newborns to the terminally ill. About 595,800 establishments make up the healthcare industry; they vary greatly in terms of size, staffing patterns, and organizational structures. About 76 percent of healthcare establishments are offices of physicians, dentists, or other health practitioners. Although hospitals constitute only 1 percent of all healthcare establishments, they employ 35 percent of all workers.

The healthcare industry includes establishments ranging from small-town private practices of physicians who employ only one medical assistant to busy inner-city hospitals that provide thousands of diverse jobs. In 2008, around 48 percent of non-hospital healthcare establishments employed fewer than five workers. In contrast, 72 percent of hospital employees were in establishments with more than 1,000 workers.

The healthcare industry consists of the following segments:

  • Hospitals provide complete medical care, ranging from diagnostic services, to surgery, to continuous nursing care. Some hospitals specialize in treatment of the mentally ill, cancer patients, or children. Hospital-based care may be on an inpatient (overnight) or outpatient basis. The mix of workers needed varies, depending on the size, geographic location, goals, philosophy, funding, organization, and management style of the institution. As hospitals work to improve efficiency, care continues to shift from an inpatient to outpatient basis whenever possible.
  • Nursing care facilities provide inpatient nursing, rehabilitation, and health-related personal care to those who need continuous nursing care, but do not require hospital services. Nursing aides provide the vast majority of direct care. Other facilities, such as convalescent homes, help patients who need less assistance.
  • Residential care facilities provide around-the-clock social and personal care to children, the elderly, and others who have limited ability to care for themselves. Workers care for residents of assisted-living facilities, alcohol and drug rehabilitation centers, group homes, and halfway houses. Nursing and medical care, however, are not the main functions of establishments providing residential care, as they are in nursing care facilities.
  • About 36 percent of all healthcare establishments are physicians’ offices . Physicians and surgeons practice privately or in groups of practitioners who have the same or different specialties. Many physicians and surgeons prefer to join group practices because they afford backup coverage, reduce overhead expenses, and facilitate consultation with peers. Physicians and surgeons are increasingly working as salaried employees of group medical practices, clinics, or integrated health systems.
  • About 20 percent of healthcare establishments are dentists' offices . Most employ only a few workers, who provide preventative, cosmetic, or emergency care. Some offices specialize in a single field of dentistry, such as orthodontics or periodontics.
  • Skilled nursing or medical care is sometimes provided in the home under a physician's supervision. Home healthcare services are provided mainly to the elderly. The development of in-home medical technologies, substantial cost savings, and patients' preference for care in the home have helped change this once-small segment of the industry into one of the fastest growing healthcare services.
  • Offices of other health practitioners include the offices of chiropractors, optometrists, podiatrists, occupational and physical therapists, psychologists, audiologists, speech-language pathologists, dietitians, and other health practitioners. Demand for the services of this segment is related to the ability of patients to pay, either directly or through health insurance. Hospitals and nursing facilities may contract out for these services. This segment also includes the offices of practitioners of alternative medicine, such as acupuncturists, homeopaths, hypnotherapists, and naturopaths.
  • Ambulatory healthcare services include outpatient care centers and medical and diagnostic laboratories. These establishments are diverse including kidney dialysis centers, outpatient mental health and substance abuse centers, blood and organ banks, and medical labs that analyze blood, do diagnostic imaging, and perform other clinical tests.
