Based on the event, the patient was not properly secured to the surgical table subsequently causing the patient to slide when the table's unexpected movement occurred.No patient restraints were used to keep the patient from sliding.The operator manual states (pp.4-8), "warning - personal injury hazard: unanticipated table movement could cause patient injury.Patient must be secured to the table in accordance with recommended positioning practices".Following the event, facility personnel tested the function and operation of the table and were unable to duplicate the un-commanded table movement.A steris service technician arrived onsite to inspect the surgical table and found the table to be operating properly.The technician was unable to duplicate the reported movement.The technician removed the table's column shroud to inspect all wiring and found the table to be operating according to specification; no repairs were required.Additionally, the technician inspected the hand control and auxiliary hand control and found both to be operating according to specification.Based on the description of the event, the reported event appears to be attributed to a powered movement via inadvertent hand control activation.No additional issues have been reported.
