MEDICAL MISADMINISTRATION The Operations Center received a call on November 26,1998, from the Radiation Safety Officer (RSO) for Queen's Medical Center, Honolulu, Hawaii, reporting a medical misadministration which had occurred on November 25,1998. The event involved a Nucletron afterloader with an Iridium (tr-192) source. The brachytherapy dosimetrist entered the wrong starting position,1500 mm rather than the intended 1450 mm. The pre-treatment data were checked by the brachytherapy physicist and the authorized user. Neither of the three individuals detected the entry error. The error was discovered later the same day while reviewing the case with a second brachytherapy physicist. The RSO was notified at home on November 25,1998, at 4:30 p.m. (HST). The patient had been treated and discharged. | |||
On November 26,1998, the RSO reviewed the case and determined the error constituted a medical misadministration. Since this was a holiday, the authorized user, brachytherapy dosimetrist, and brachytherapy physicist were not available. The referring physician and patient were notified on November 25,1998. The patient received 500 cGy (500 rads) to an unintended section of the right bronchus. It is unlikely that this dose will be harmful to the tissues. | |||
