Court records show one family reached a $250,000 settlement with the Columbus-area Mount Carmel Health System over a May 2017 death.
Mount Carmel confirmed two more cases were resolved, but details haven't been shared.
A statement from President and CEO Edward Lamb says Mount Carmel hopes that resolving the cases brings the families "some measure of closure and comfort."
Mount Carmel fired the doctor, William Husel (HYOO'-suhl), in December. He remains under investigation.
The 43-year-old doctor and the hospital faced more than two dozen wrongful-death lawsuits. Court filings for Husel in some of those deny he negligently or intentionally caused deaths.
