The following information was received by the
Ohio Department of Health via email:
On February 7, 2025, the Ohio Department of Health was notified of a medical event involving Y-90 TheraSpheres. Two patients were scheduled to receive treatment on February 7, 2025, however, patient 'A' received the dose prescribed to patient 'B'. The written directive stated patient 'A' was to receive 160 Gy (47 mCi) but instead received 92 Gy (27 mCi), resulting in an underdose of 43 percent. The apparent cause was due to transposing the vial lot numbers when entering the information into the hospital's patient tracking system. The hospital caught the error before patient 'B' was treated, and patient 'B' received the dose prescribed in the written directive. Patient 'A' and his physician were notified. The patient will be evaluated to determine if additional treatment is required. An investigation of this event is pending.
