The relationship between hospital and intensive care unit length of stayAndrew A Kramer
Cerner Corporation, Vienna, VA, USA
Crit Care Med 39:1015-22. 2011..To assess variations in case-mix-adjusted hospital and intensive care unit length of stay and to examine the relationship between intensive care unit and hospital stay...

A predictive model for the early identification of patients at risk for a prolonged intensive care unit length of stayAndrew A Kramer
Cerner Corporation, Suite 500, Vienna, Virginia 22182, USA
BMC Med Inform Decis Mak 10:27. 2010..Early identification of patients at risk for a prolonged length of stay can lead to quality enhancements that reduce ICU stay. This study developed and validated a model that identifies patients at risk for a prolonged ICU stay...
Predicting outcomes for cardiac surgery patients after intensive care unit admissionAndrew A Kramer
Cerner Corporation, Vienna, Virginia 22182, USA
Semin Cardiothorac Vasc Anesth 12:175-83. 2008..Thus, the equations are not designed for predicting individual patients' outcome but have proven useful in performance comparisons and for quality improvement initiatives...

George Washington University, Washington, DC, USA
Crit Care Med 34:2517-29. 2006..APACHE IV benchmarks for ICU stay are useful for assessing the efficiency of unit throughput and support examination of structural, managerial, and patient factors that affect ICU stay...
