OBJECTIVE : We sought to compare timing of intervention for patients with spinal cord injury (SCI) requiring surgical procedures during weekend versus weekday admissions.
METHODS : The National Inpatient Sample database from 2012 to 2014 was queried to identify patients with SCI who underwent surgical treatment (decompression with or without stabilization) as an emergent/urgent procedure. Timing of intervention, inpatient morbidity, and inpatient mortality were compared between patients admitted during the weekend versus a weekday. Multiple logistic regression analyses were also performed.
RESULTS : A total of 9390 patients were identified (mean age 55 years, 73.2% male) from the database, with 34.1% admitted during the weekend and 65.9% during a weekday. The average day of intervention for the entire cohort was 2.8 (SD 3.9, interquartile range 1-4); day 2.7 (standard deviation [SD] 4.0) versus day 2.8 ([SD] 3.9) for patients admitted in a weekend versus weekday (P = 0.418). After controlling for patient age, sex, and injury severity score on multiple logistic regression analysis, weekend admission was not significantly associated with early intervention (odds ratio [OR] 0.99; 95% confidence interval [CI], 0.82-1.21; P = 0.993), complication occurrence (OR 1.09; 95% CI, 0.86-1.38; P = 0.476), or inpatient mortality (OR 0.83; 95% CI, 0.44-1.56; P = 0.563). Patients with complete/American Spinal Injury Association A injuries were more likely to undergo early intervention (OR 2.09; 95% CI, 1.31-3.31; P = 0.002).
CONCLUSIONS : In this national study, patients with SCI who were admitted during the weekend received surgical intervention as early as patients admitted during a weekday. Furthermore, no differences in complication or mortality rates between groups were found.
