| Abstract |
Objective
Several studies have indicated that short-term mortality risk is higher among aneurysmal subarachnoid hemorrhage (aSAH) patients who are admitted on the weekends. This so called “weekend effect” has been observed among patients admitted with a variety of diagnoses, including myocardial infarction, pulmonary embolism and stroke. This study examines the relationship between short-term mortality risk and weekend admission among patients hospitalized following aSAH.
Methods
This retrospective cohort study analyzes mortality outcomes among aSAH patients who had been admitted to hospital between July 01 2006 and December 31 2008. Patients included in this cohort were identified using the patient enrollment log for SAH and the electronic hospital information system. Patients who denied neurosurgical treatment were excluded. Multivariable logistic regression analyses and Cox proportional hazard regression analyses were used to measure the association of weekend admission on mortality for patients with aSAH, adjusted for differences in patient characteristics that also contribute to mortality risk such as Hunt-Hess grade and Fisher’s grade of SAH.
Results
Weekend admissions occurred 125 (40.8%) among the 306 patients with aSAH who met inclusion criteria during the study period. There is no statistically significant difference in the risk of in-hospital death associated with hospital admission on either Saturday, Sunday or holiday among patients with aSAH as compared to weekday admission.
Conclusion
Weekend admission in aSAH patient is not significantly associated with the worse outcome as compared to weekday admission. So called the ‘weekend effect’ tends to occur in a disease specific and a healthcare system specific way. |
