Companies in this industry, which include physicians, dentists, outpatient care centers, and imaging and diagnostic facilities, provide health care services to ambulatory patients. Major companies include Apria Healthcare, AmSurg, DaVita HealthCare (all based in the US), as well as Fresenius (Germany), LVL Médical Groupe (France), and Sonic Healthcare (Australia).
Demand for health care services is driven by demographics and advances in medical care and technology. The profitability of individual companies depends on efficiency, reputation, and expertise. Large companies have advantages in buying supplies and in negotiating contracts with health insurers. Small companies can compete successfully by serving a limited geographical area, offering specialized services, or building a local reputation for quality care. The US ambulatory health care industry is highly fragmented: the top 50 companies generate only about 10 percent of revenue.
Major services include care provided by physicians, which accounts for about 50 percent of industry revenue; dentists and outpatient care centers account for about 12 percent each. Other sources of revenue include medical and diagnostic laboratories, blood banks, home health care, rehabilitation therapy, and ambulance services. Health care in the US is led by for-profit entities, an exception to the global norm of nationalized medicine.
