The following report was received from the
Pennsylvania Bureau of Radiation Protection via facsimile:
The event involved a patient who was scheduled to be treated with 16 mCi of Y-90 SirSpheres to the left lobe of the liver. The written directive (WD), however, was incorrectly written for the right lobe of the liver. The authorized user (AU) did in fact deliver the correct dose to the correct lobe and the discrepancy was only noticed after the procedure was complete. No harm is expected as the patient received the intended dose to the correct location. The cause of the event was noted as human error resulting from:
(1) Failure of the AU to indicate the correct treatment site on the WD.
(2) Failure of the AU to forward documentation of the pre-therapy information to the RSO (or designee) prior to the therapy.
(3) Failure of clinical staff to identify the discrepancy on the WD during the patient time out just before implantation of the microspheres.
Corrective actions include: Before drawing up the dose/activity in Nuclear Medicine (and preferably before the dose/activity is ordered from the manufacturer), the AU must forward pre-therapy documentation (WD, pre-post therapy worksheet, etc.) to the RSO (or designee) to ensure documentation is correct/appropriate.
The Department [Pennsylvania Bureau of Radiation Protection] will perform a reactive inspection. The licensee will update their procedure to include additional checks for the written directive.
