The following information was received via email from the State of Oklahoma:
[State of Oklahoma] has been informed that MUSKOGEE REGIONAL MEDICAL CENTER, LLC dba EASTAR HEALTH SYSTEM (OK-13157-01) administered 10 mCi of Tc-99m to a patient without an order from an Authorized User. This was done on the basis of a phone call from a nurse on the ward who indicated the patient was to have a stress test. After the initial dose had been administered, the physician [patients attending physician] called the Nuclear Medicine department and informed them that no study had been ordered for this patient. The second dose was not administered. The highest dose resulting from the administration is 1.25 REM to the gallbladder and 340 mR whole body. This does not appear to be a medical event.
The State of Oklahoma did not know if the patient has been informed of the misadministration.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
