COLUMBUS (AP) — An Ohio hospital’s chief pharmacy officer has left the job amid allegations that employees there ordered, approved and administered possibly fatal doses of pain medication for dozens of patients over several years.

Mount Carmel Health System won’t say whether Janet Whittey’s Feb. 5 departure from Columbus’ Mount Carmel West was voluntary or forced. Her email notification to the Board of Pharmacy gave no explanation.

Mount Carmel apologized and put other staff on leave after discovering a now-fired intensive care doctor, William Husel, ordered excessive doses for 34 patients. That’s under investigation.

One of the 15 related lawsuits against Husel and the hospital also names Whittey .

She has no attorney listed and hasn’t responded to attempts to reach her by email and phone.

Husel’s lawyers aren’t commenting on the allegations.
