During a Health Physics audit, while reviewing seed implantation cases, the auditor was reviewing a procedure performed on a patient on 2/13/04. The procedure involved an
I-125 seed implantation that delivered 5000 Rad to the patient's prostate. The auditor saw a notation in the record that a previous implantation on 12/15/03 had also delivered 5000 Rad to the same patient's prostate.
When the auditor pulled the record for the 12/15/03 implantation, he discovered that the intended dose from the procedure was 10,000 Rad. He proceeded to call Radiation Medicine Center, the licensee who performed both procedures (License # 2902023-06). Radiation Medicine Center stated that, when evaluating the patient in mid-January, they discovered, via CT scan and dosimetry, that the patient had only received 5000 Rad during the first procedure, and that is why the second procedure was performed on 2/13/04.
The auditor is reporting the implantation from 12/15/03 as a Medical Event.
- * * UPDATE ON 03/09/04 @ 0956 BY IRA GARELICK TO C GOULD * * * RETRACTION
The licensee is retracting this event on the basis that further investigation along with consultation and a site visit with Reg 1 NRC personnel determined the implant went as planned. There was some tissue shrinkage resulting in cold spots which were adequately treated in the second implant on 02/13/04.
