AGREEMENT STATE REPORT - INCORRECT DOSE DELIVERED TO PATIENT

The following information was received from the state of California via email:

"On January 25, 2021, the Radiation Safety Officers [RSO] discovered and reported to CDPH [California Department of Public Health] that a medical event had occurred on December 28, 2020. The RSO stated that during a routine review of the past month's radiation therapies, they discovered that a Y-90 Nordion TheraSphere treatment performed on 12/28/2020 resulted in a delivered dose that was approximately 33 percent greater than the physician's written directive (550 Gy) signed on 12/15/2020. This higher patient dose was the result of administering the dose on Monday (12/28/2020) that was calibrated for administration on Tuesday (12/29/2020). The licensee will be submitting their 15 day report per 10 CFR 35.3045."

California report no.: 012521
