The following information was obtained from the State of
Ohio via email:
ODH [Ohio Department of Health] received information on 3/3/10 of a unreported medical event that occurred at Mercy St. Vincent Medical Center in Toledo on 11/8/05. ODH performed an on-site investigation on 3/5/10 and confirmed the unreported medical event. On 11/8/05, the licensee performed a prostate seed implant with 67 I-125 seeds prescribed to deliver a dose of 160 Gray to the prostate. Thirteen seeds were removed from the bladder immediately after the procedure leaving 54 seeds in the patient. A post implant dose calculation showed an under dose to the prostate greater than 20% of the prescribed dose. The licensee then performed an external beam treatment with a linear accelerator to treat the tumor.
ODH is continuing the investigation of this event along with other brachytherapy cases performed by the licensee. ODH is also requesting assistance from the NRC's contract medical expert in evaluating the event.
