No criminal charges will be brought against St. Charles Bend in the medication-error death of Loretta Macpherson.

The 65-year-old Sisters resident died Dec. 3, 2014 when a staff member in the hospital’s inpatient pharmacy filled an IV bag with the wrong medication.

The decision not to prosecute was announced Monday evening in a news release from the Deschutes County District Attorney’s Office.

“After a thorough review of the facts of this case, and a consideration of the steps St. Charles has taken to ensure a tragedy like this never happens again, I concluded that forgoing the initiation of criminal charges was in the interest of justice,” District Attorney John Hummel said in the release.

At a news conference in December 2014, Dr. Michel Boileau, St. Charles’ chief clinical officer, said that the correct drug had been entered into the hospital’s electronic medical records system and the pharmacy had received the correct order. The error occurred when the IV bag that would go to Macpherson was inadvertently filled with the paralyzing agent instead of the anti-seizure drug that had been ordered for her. The IV bag and the vials of medication were then labeled with a bar code indicating they were fosphenytoin, the anti-seizure drug the physician had ordered, he said.

According to the release, Hummel met with hospital administrators following the death regarding measures recommended by the Institute for Safe Medication Practices.
