On March 14, 2019, the Texas Department of Health Services was notified by the licensee's radiation safety officer (RSO) that a therapy event had occurred. A patient was scheduled for three fractions using a high dose rate after loader containing a 6.8 curie iridium-192 source. Multiple catheters were to be used. On March 14, 2019, prior to the third fraction, the licensee determined that one of the catheters was shorter than the length required and the patient received 350 centigrays (50 percent) of the prescribed dose to the thigh resulting in the target tissue receiving 50 percent of the prescribed dose (350 centigrays). The third fraction was not administered. The RSO stated they intended to create a new treatment plan to correct the error and insure the intended area receives the correct dose. Additional information will be provided as it is received in accordance with SA-300.
