For a study, the researchers aimed to identify patient and hospital-level factors independently related to the receipt of nonelective surgery and judged whether nonelective surgery portends differences in perioperative outcomes compared to elective surgery for spinal metastases. After disease-related factors and other baseline covariates, multivariable logistic regression models revealed several sociodemographic contrasts in the receipt of nonelective surgery. Patients of black (odds ratio [OR]=1.38, 95% CI:1.03–1.84, P=0.032) and other races (OR=1.50, 95% CI:1.13–1.98, P=0.005) were seen to have greater odds of undergoing nonelective surgery than their white counterparts. Patients of lower-income (OR=1.40, 95% CI: 1.06–1.84, P=0.019) and public insurance status (OR=1.56, 95% CI: 1.26–1.93, P<0.001) were more likely to receive nonelective surgery than higher income and privately insured patients, respectively. Higher comorbidity burden was also related to higher odds of non-elective admission (OR=2.94, 95% CI:2.07–4.16, P<0.001). With respect to perioperative outcomes, multivariable analysis displayed that patients receiving nonelective surgery are more likely to experience nonroutine discharge (OR=2.50, 95% CI: 2.09–2.98, P<0.001) and extended length of stay [LOS] (OR=2.45, 95% CI:1.91–3.16, P<0.001). The researchers demonstrated substantial disparities in the receipt of nonelective surgery across sociodemographic groups and highlighted its relation with non-routine discharge and extended LOS.
