Mercy Health Network tends to the hearts (and other body parts) of the Heartland through its collection of hospitals, clinics, nursing homes, and other health care operations. The integrated health network, formed through a joint operating agreement between Catholic Health Initiatives and Trinity Health, manages hospital systems in five Iowa cities: Clinton, Des Moines, Dubuque, Mason City, and Sioux City. The network also includes several rural hospitals and affiliated facilities. The largest hospital group is Mercy Medical Center-Des Moines, which consists of three campuses (including a mental health facility) with more than 900 inpatient beds. All together, Mercy Health Network boasts more than 2,000 beds.
