On 9/21/06 at Sewickley Valley Hospital, a technician removed a vial of I-131 therapy capsules and measured the dose in the dose calibrator to ensure that the dose measured the expected amount of 25 millicuries. The dose was administered to the patient by emptying the contents of the vial into the patient's hand. Only one of the I-131 capsules came out of the vial instead of two. The vial was placed back into the shipping container
and returned to the pharmacy.
On 9/25/06, the pharmacy notified Sewickley Valley Hospital that they had returned one of the two capsules to the pharmacy. One of the two capsules had apparently remained in the vial during the administration to the patient. The RSO reported that the dose to the patient was approximately 5 millicuries instead of the 25 millicurie prescribed dose. The hospital has already contacted the referring physician and plans on contacting the patient to make arrangements to administer the rest of the prescribed dose. The hospital will also institute changes in their procedures requiring the vial to be visually inspected and checked in the dose calibrator following use to prevent this from happening in the future.
