background: left ventricular dysfunction is one of the most powerful predictors of early and late outcomes in patients who undergo coronary artery bypass grafting (cabg). the aim of this study was to assess the early results of cabg that predict 30-day mortality and prolonged length of hospital stay (los) after cabg in patients with an ejection fraction (ef) of 30% or less. methods: seven hundr...

Background Measuring and understanding main determinants of length of stay (LOS) in emergency departments (EDs) is critical from an operations perspective, since LOS is one of the main performance indicators of ED operations. Therefore, this study analyzes both the main and interaction effects of four widely-used independent determinants of ED-LOS.   Methods The analysis...

The primary aim of the research reported here is to examine elements of the theory of social organizations as adaptive systems as derived from Roy's model by investigating the ability of hospital payment source to predict length-of-stay. A retrospective review was conducted of 3,297 records of patients discharged under 1 of 10 frequently occurring diagnosis-related-groups. Two groups were forme...

HYPOTHESIS Decreased length of stay (LOS) after pancreatoduodenectomy is due to multiple factors, including a lower complication rate and more efficient perioperative care for all patients, with and without complications.
