The following information was received by the State of
Ohio via email:
The licensee performs prostate seed implants on Tuesdays and Thursdays each week. End of day inventories are performed by two therapists. At the end of day inventory on 1/4/2022 the licensee had 53 unused seeds. The beginning of day inventory on 1/6/2022 the inventory was 52 seeds. No procedures were conducted between 1/4/22 and 1/6/22, and surveys did not locate the missing seed. The licensee is unable to account for the discrepancy in their inventory.
