Measuring the Impact of ICU Strain on Mortality, After-Hours Discharge, Discharge Delay, Interhospital Transfer, and Readmission in Australia With the Activity Index*
Main finding · In-hospital mortalityResult — go to the resultOdds ratio 1.49 99% CI 1.38–1.60Authors' conclusion
The Activity index is a simple and valid measure that identifies ICUs in which increasing strain leads to progressively worse patient outcomes.
