Relative to primary cases, those undergoing revision correction of spinal deformity have a higher risk of many procedure-related complications with a longer hospital course despite similar baseline comorbidity burden and the in-hospital mortality rate. This study provides clinically useful data for surgeons to educate patients at risk for morbidity and mortality and direct future research to improve outcomes.

Longer fusions were associated with increased morbidity. Age >65 was associated with increased morbidity/mortality, while females were associated with increased morbidity but decreased mortality. Idiopathic scoliosis had decreased morbidity. Degenerative ASD cases had higher comorbidity indices, potentially due to older age. This study is clinically useful for patient education, surgical decision-making, and optimizing patient outcomes.
