Notifications: DEP [PA Department of Environmental Protection] received a letter dated May 1, 2009; Received May 8, 2009 from St. Luke's describing the incident, corrective actions, effects and notification to the patient.
A patient was administered a therapeutic dose of 134 mCi of I-131 for thyroid carcinoma on April 11, 2008. She had previous negative pregnancy tests on April 6, 2008 and April 10, 2008. Following treatment the patient suspected she was pregnant and returned to the hospital an April 28, 2008. Subsequent testing indicated she became pregnant approximately 4 to 6 days following her treatment. Calculated dose to the fetus was 35 rad, whole body dose. Patient and referring physician both notified. The event occurred because the patient didn't follow the contraceptive plan outlined in the procedure she signed prior to treatment. The hospital staff followed procedure for therapeutic administration of I-131, however corrective actions involve procedure modifications such as over-emphasizing the risks associated with becoming pregnant following administration of radioiodine to prevent further occurrence.
