Event description: On March 18, 2014, the licensee identified an error in a dose calculation for high dose rate (HDR) treatments administered to a patient on March 11-12. The initial report from the licensee indicates the patient was administered two out of a total of six prescribed fractionated doses. An error was made in planning the correct dwell position for the two fractions. The administered dose differed from the prescribed dose (was less than) by more than 20 percent. The licensee plans to correct for the underdose during the remaining fractions. The licensee is investigating if the dose to tissues other than the treatment site may have met the definition of a medical event.
