BACKGROUND: Recent studies in surgical and non-surgical specialities have suggested that patients admitted on the weekend may have worse outcomes. In particular, patients with stroke and acute cardiovascular events have shown worse outcomes with weekend treatment. It is unclear whether this extends to patients with spinal cord injury (SCI). This study was designed to evaluate factors for readmission after index hospitalization for spinal cord injury.
METHODS: This cohort was constructed from the State Inpatient Databases of California, New York, and Florida. 14,396 patients with SCI were identified. The primary outcome measure evaluated was 30-day readmission. Secondary measures include in-hospital complications. Univariate and multivariate analysis were utilized to evaluate covariates. χ2, Fisher’s exact, and linear, logistic, and modified Poisson regression methods were utilized for statistical analysis. Propensity score methods were used with matched pairs analysis performed by the McNemar’s test.
RESULTS: Weekend admission was not associated with increased 30- day readmission rates in multivariate analysis. Race and discharge to a facility (RR 1.60 (1.43-1.79)) or home with home care (RR 1.23 (1.07-1.42)), were statistically significant risk factors for readmission. Payor status did not affect rates of readmission. In propensity score matched pairs analysis, weekend admission was not associated with increased odds of 30-day readmission (OR 1.04 (0.89-1.21)). Patients admitted to high volume centers had significantly lower risk of readmission when compared with patients admitted to low volume centers.
CONCLUSION: Our results suggest that the weekend effect, described previously in other patient populations, may not play as important a role in patients with SCI.
