Dedicated spine nurses and scrub technicians improve intraoperative efficiency of surgery for adolescent idiopathic scoliosis.

STUDY DESIGN

Retrospective comparative study.

OBJECTIVE

To determine how the use of dedicated spine surgical nurses and scrub technicians impacted surgical outcomes of posterior spinal fusions for adolescent idiopathic scoliosis (AIS). Dedicated team approaches to surgery have been shown to improve surgical outcomes. However, their study on orthopaedics and spine surgery is limited.

METHODS

A retrospective review of all patients who underwent a primary posterior spinal fusion of seven or more levels for AIS at a tertiary care pediatric hospital with a minimum of 2 years of follow-up from 2006 to 2013 was conducted. Our institution had dedicated spine surgeons and anesthesiologists throughout the study period, but use of dedicated spine nurses and scrub technicians was variable. The relationship between the proportion of nurses and scrub technicians that were dedicated spine and surgical outcome variables was examined. A multiple regression was performed to control for the surgeon performing the case and the start time.

RESULTS

A total of 146 patients met criteria. When teams were composed of < 60% dedicated spine nurses and scrub technicians, there was 34 min more total OR time (p = .008), 27 min more surgical time (p = .037), 7 min more nonsurgical OR time (p = .030), 30% more estimated blood loss (EBL) (p = .013), 27% more EBL per level instrumented (p = .020), 113% more allogeneic transfusion (p = .006), and 104% more allogeneic transfusion per level instrumented (p = .009). There was no significant difference in length of stay, unplanned staged procedures, surgical site infection, reoperation, or major medical complications.

CONCLUSIONS

Performing posterior spinal fusions for AIS patients with dedicated spine nurses and scrub technicians is associated with a significant decrease in total OR time, blood loss, and transfusion rates.
