IOWA CITY — While the health care system statewide grappled with a record number of coronavirus patients over the past several weeks, the University of Iowa Hospitals and Clinics’ “virtual hospital” program has helped alleviate some of the pressure, officials say. The UIHC Home Treatment Team, which started early in the coronavirus pandemic, is a targeted initiative that provides daily direct care at home, in an effort to keep COVID-19 patients out of the hospital.The team now has seen about 1,300 patients with high risk for complications of the virus.
