Estimated blood loss (EBL), length of stay (LOS), operating room (OR) time, complications, quality of life (Health Related Quality of Life), and x-rays were analyzed. Outcomes were compared between one-surgeon (1S) and two-surgeon (2S) centers. A deformity-matched cohort was analyzed.<h4>Results</h4>A total of 188 patients in 1S and 77 in 2S group were included. 2S group patients were older and had worse deformity based on the Scoliosis Research Society-Schwab classification (P < 0.05). There were no significant differences in levels fused (P = 0.57), LOS (8.7 vs 8.9 days), OR time (445.9 vs 453.2 min), or EBL (2008 vs 1898 cm; P > 0.05). 2S patients had more three-column osteotomies (3CO; P < 0.001) and used less bone morphogenetic protein 2 (BMP-2; 79.9% vs 15.6%; P < 0.001). The 2S group had fewer intraoperative complications (1.3% vs 11.1%; P = 0.006). Postoperative (6 wk to 2 yr) complications were more frequent in the 2S group (4.8% vs 15.6%; P < 0.002). After matching for deformity, there were no differences in (9.1 vs 10.1 days), OR time (467.8 vs 508.4 min), or EBL (3045 vs 2247 cm; P = 0.217). 2S group used less BMP-2 (20.6% vs 84.8%; P < 0.001), had fewer intraoperative complications (P = 0.015) but postoperative complications due to instrumentation failure/pseudarthrosis were more frequent (P < 0.01).<h4>Conclusion</h4>No significant differences were found in LOS, OR time, or EBL between the 1S and 2S groups, even when matching for severity of deformity. 2S group had less BMP-2 use, fewer intraoperative complications but more postoperative complications.<h4>Level of evidence</h4>2.International Spine Study GroupHumansScoliosisTreatment OutcomeLength of StayRetrospective StudiesFollow-Up StudiesProspective StudiesAdultMiddle AgedMedical Staff, HospitalPatient Care TeamFemaleMaleOperative TimeSurgeonsAdult Scoliosis Deformity Surgery: Comparison of Outcomes Between One Versus Two Attending Surgeons.Journal article2023-07-09
