A report says the Dayton VA medical center is investigating allegations of improper conduct by an employee.
Allegations have been made that a doctor drew blood from patients under anesthesia without their knowledge or consent.
The Dayton Daily News reports the claim was made anonymously to the VA's Office of Inspector General, and a review is underway.
The newspaper also says a complaint alleges the doctor improperly kept a supply of the powerful sedative Propofol in his office that wasn’t monitored or managed through the VA pharmacy even while there was a nationwide shortage of the drug in 2009.
