Kaplan, et al. v. Mayo Clinic, et al.

by
Plaintiff and his wife (the Kaplans) filed suit against Mayo Clinic Rochester, Inc., other Mayo entities (collectively, Mayo), and Mayo doctors David Nagorney and Lawrence Burgart, making a number of claims arising out of plaintiff's erroneous diagnosis of pancreatic cancer and plaintiff's surgery based on that diagnosis. The Kaplans subsequently appealed the judgments in favor of Mayo and Dr. Burgart on their negligent-failure-to-diagnose and contract claims. The court held that the error, if any, in admitting a certain medical file, which included insurance documents, into evidence did not affect the Kaplans' substantial rights and the Kaplans were not prejudiced by the district court's decision not to give a limiting instruction. The court agreed with the district court that the Kaplans' assertion that the biopsy slides might have been tampered with was based on rank speculation where they failed to present evidence that the slides had been changed in any way. The court also held that the Kaplans have shown no basis for granting them a new trial on their claim for negligent failure to diagnose. The court held, however, that the district court erred in granting judgment as a matter of law where the Kaplans have offered sufficient evidence in their case-in-chief to support a breach-of-contract claim. Accordingly, the court affirmed in part, reversed in part, and remanded for further proceedings.
