IOWA CITY — While warning of an unprecedented mountain of financial challenges ahead and a likely $2 million deficit at the end of what began as a banner budget year, University of Iowa Health Care officials on Thursday also touted remarkable achievements so far in their COVID-19 response.Thanks to a rapid ramp up of protective equipment supplies, visitor restrictions, an influenza-type-illness clinic, telehealth consultations, drug trials, and new screening protocols — among other things — UI Hospitals and Clinics to date has achieved a 99.7 percent COVID-19 survival rate.“Our survival rates for patients who we follow from initial diagnosis of their coronavirus infection is 99.7 percent, which is among the best survival rates anywhere in the world,” UIHC Vice President for Medical Affairs Brooks Jackson told his campus’ governing Board of Regents on Thursday.
