Methods We used a retrospective cohort analysis 2008 Nationwide Emergency Department Sample. Evaluating 4 225 973 adults admitted through hospital, signifying 20% representative sample admissions. Logistic regression was associations and characteristics, accounting clustering by hospital. Results department significantly more likely die those weekdays (odds ratio, 1.073; 95% confidence interval, 1.061-1.084). A significant effect persisted after controlling 1.026; 1.005-1.048). top 10 diagnoses dying did not identify any specific medical condition that explained higher admission also relatively consistent across status, ownership, status. Conclusion Patients when weekend. were unable circumstances attributes help explain this phenomenon. Although relative risk per case small, our demonstrates number potentially preventable deaths occurring annually in United States.
