| Title | Patient Underdose |
| Event Description | The following information was received from Illinois Emergency Management Agency (Agency) via phone and E-mail:
At 1545 CST on 1/27/2022, the Agency was contacted by Northwestern Memorial Hospital (IL-01037-02) of a potential medical event. No adverse patient impact reported. The administration was able to be completed that same day. This event was reported to the NRC Headquarters Operations Officer (1/28/22) this afternoon. Agency inspectors performed a reactive inspection on 1/28/2022 at Central DuPage Hospital. On 1/27/2022, a written directive to deliver 3.25 GBq Y-90 SIR-Spheres to the right hepatic artery was prepared. The procedure performed that same day was halted prematurely due to an occlusion of microspheres in the delivery line. [Surveys of the delivery equipment indicated no microspheres were delivered to the patient.] To compensate for the underdose, the licensee created two additional written directives and administered two doses of 1.55 GBq Y-90 SIR-Spheres each without incident. The licensee is continuing their investigation into root cause. [Agency will review the investigation results.] Item Number: IL220002 A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. |
