COLUMBUS (AP) — More families are suing an Ohio hospital and a critical-care doctor accused of ordering excessive doses of pain medication for dozens of patients who died.

The Columbus-area Mount Carmel Health System and now-fired Dr. William Husel face at least 22 wrongful-death lawsuits.

New lawsuits were filed over the past few days about the deaths of 55-year-old Corrinnia Blake last September; 83-year-old Thelma Kyer in March 2017; and 78-year-old Lora Stone in May 2017. The lawsuits allege those women died after they were administered excessive doses of the powerful painkiller fentanyl.

Mount Carmel found Husel ordered potentially fatal drug doses for 29 patients over several years. It says six more got doses that were excessive but not likely what caused their deaths.

Mount Carmel has apologized. Husel’s lawyers aren’t commenting.
