“…There is reasonable, and continuing, evidence that interaction display systems are useful clinical tools associated with a range of useful outcomes including: reduced drug use [16–19,20 ▪ ,21 ▪ ]; improved postoperative analgesia [20 ▪ ]; more stable anesthesia [17,21 ▪ ]; facilitating a wake-up test during scoliosis surgery [22]; and, in one study, use of SmartPilot was associated with reduced complications and a shorter hospital stay [17].
