The health care industry consists of the following nine segments:
Hospitals. 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. Many hospitals have expanded into long-term and home health care services, providing a wide range of care for the communities they serve.
Nursing and residential care facilities. 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
Offices of physicians. About 37 percent of all health care establishments fall into this industry segment. 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. Most medical assistants work in doctors offices.
Offices of dentists. About 1 out of every 5 health care establishments is a dentist’s office. Most employ only a few workers, who provide general or specialized dental care, including dental surgery.
Home health care services. Skilled nursing or medical care is sometimes provided in the home, under a physician’s supervision. Home health care 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 parts of the economy.
Offices of other health practitioners. This segment of the industry includes 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.
Outpatient care centers. The diverse establishments in this group include kidney dialysis centers, outpatient mental health and substance abuse centers, health maintenance organization medical centers, and freestanding ambulatory surgical and emergency centers.
Other ambulatory health care services. This relatively small industry segment includes ambulance and helicopter transport services, blood and organ banks, and other ambulatory health care services, such as pacemaker monitoring services and smoking cessation programs.
Medical and diagnostic laboratories. Medical and diagnostic laboratories provide analytic or diagnostic services to the medical profession or directly to patients following a physician’s prescription. Workers may analyze blood, take x rays and computerized tomography scans, or perform other clinical tests. Medical and diagnostic laboratories provide the fewest number of jobs in the health care industry.
In the rapidly changing health care industry, technological advances have made many new procedures and methods of diagnosis and treatment possible. Clinical developments, such as organ transplants, less invasive surgical techniques, skin grafts, and gene therapy for cancer treatment, continue to increase the longevity and improve the quality of life of many Americans. Advances in medical technology also have improved the survival rates of trauma victims and the severely ill, who need extensive care from therapists and social workers as well as other support personnel.
In addition, advances in information technology continue to improve patient care and worker efficiency with devices such as hand-held computers that record notes on each patient. Information on vital signs and orders for tests are transferred electronically to a main database; this process eliminates the need for paper and reduces recordkeeping errors.
Cost containment also is shaping the health care industry, as shown by the growing emphasis on providing services on an outpatient, ambulatory basis; limiting unnecessary or low-priority services; and stressing preventive care, which reduces the potential cost of undiagnosed, untreated medical conditions. Enrollment in managed care programs—predominantly preferred provider organizations, health maintenance organizations, and hybrid plans such as point-of-service programs—continues to grow. These prepaid plans provide comprehensive coverage to members and control health insurance costs by emphasizing preventive care. Cost effectiveness also is improved with the increased use of integrated delivery systems, which combine two or more segments of the industry to increase efficiency through the streamlining of functions, primarily financial and managerial. These changes will continue to reshape not only the nature of the health care workforce, but also the manner in which health care is provided.
