Hospital network

A hospital network is a public, non-profit or for-profit company or organization that provides two or more hospitals and other broad healthcare facilities and services. A hospital network may include hospitals in one or more regions within one or more states within one or more countries. A hospital network has one headquarter, usually within one of the regions served by the network facilities. (The term hospital system or health care system is used more broadly to define the organization of people, institutions, and resources that deliver health care services to meet the health needs of a region or country.)


Some of the earliest hospital networks were affiliated with charitable, religious organizations. The Catholic Church established a hospital network in Medieval Europe that was vastly improved from the merely reciprocal hospitality of the Greeks and family-based obligations of the Romans. These hospitals were established to cater to "particular social groups marginalized by poverty, sickness, and age," according to historian of hospitals, Guenter Risse.

In the late 20th century hospital networks were established to make delivery of healthcare more efficient and to share specialized medical services and physicians across the network. To avoid financial losses due to shrinking reimbursements and rising costs as well as improving quality of care and avoid duplication of services, hospitals may consolidate certain services at one hospital. However, patients may need to travel farther if those services are no longer offered at their local hospital.
