Risk factors for mortality after 3-column osteotomy

Area of Science:

• Spine surgery
• Orthopedic surgery
• Surgical outcomes research

Background:

• Three-column osteotomies (3COs) are critical surgical procedures for correcting rigid adult spinal deformities (ASD).
• While complications are well-documented, risk factors for mortality after 3COs require further investigation.

Purpose of the Study:

• To identify demographic and medical risk factors associated with 30-day mortality following three-column osteotomies (3COs).
• To determine the overall mortality rate after 3CO procedures.

Main Methods:

• Retrospective analysis of the National Surgical Quality Improvement Program (NSQIP) database.
• Identification of patients undergoing 3COs using CPT codes.
• Statistical analysis including univariate and multivariable logistic regression to assess risk factors for 30-day mortality.

Main Results:

• The study included 1,441 patients, with an overall 30-day mortality rate of 1.2%.
• Univariate analysis identified diabetes, COPD, and higher frailty index as significant risk factors.
• Multivariable analysis revealed independent associations between mortality and longer operative times (OR=1.28) and COPD (OR=10.36).

Conclusions:

• The 30-day mortality rate following three-column osteotomies is low at 1.2%.
• Chronic obstructive pulmonary disease (COPD) and prolonged surgical duration are independent predictors of increased mortality.
• Identifying and managing risk factors like COPD and optimizing operative time are crucial for improving patient outcomes.
