Comparative effectiveness research has a vital role in recent health reform and policies. Specialty training is one of these provider-side variables and surgeons who were trained in different specialties may have different outcomes upon performing the same procedure. The objective of this retrospective 1:1 propensity score-matched cohort study was to investigate the impact of spine surgeon specialty (neurosurgery vs orthopedic surgery) on early perioperative outcome measures of elective

Propensity score matching and subgroup analysis were utilized. After controlling for baseline characteristics in both groups (single/multi-level PLIF/TLIF), patients operated on by neurosurgeons were more likely to have longer operation time (239 vs 205 minutes / 276 vs 254 minutes), shorter total hospital stay (75 vs 96 hours / 85 vs 103 hours), lower return to operating room rates within the same admission (2.2% vs 4.2% / 2.5% vs 4.3%), lower non-home discharge (8.8% vs 12.7% / 10.8% vs 18.2%), lower discharge rate after postoperative day 3 (28% vs 31.8% / 38.1% vs 43.9%), lower readmission rates (4.4% vs 6.5% / 4.5% vs 7.5%) and lower perioperative blood transfusion rate (2.7% vs 6.0% / 11.0% vs 14.1%), (p < 0.05). Other outcome measures and mortality rates were similar among the 2 cohorts in both groups. Our analysis found significant differences in early perioperative outcomes of patients undergoing PLIF/TLIF by neurosurgeons and orthopedic surgeons. These differences have significant clinical and cost implications for patients, physicians, program directors, payors and health systems.
