DES MOINES, Iowa [KCCI-TV] — MercyOne (in Des Moines) is calling its transition to a new anesthesia provider successful, but admits some patients will have their surgeries delayed. Last month, MercyOne cut ties with its longtime partner, Medical Center Anesthesiologists. It’s now working with a company called Vituity.

In a statement, MercyOne says it prioritizes surgeries on a case-by-case basis and that some surgery dates and times are being changed. The hospital says, “We regret any stress and inconvenience this may cause, but we can assure patients we will only reschedule to bring the best level of care they have come to expect at MercyOne.”
