Multicenter Study Comparative StudyIntensive Care Society's Acute Physiology and Chronic Health Evaluation (APACHE II) study in Britain and Ireland: a prospective, multicenter, cohort study comparing two methods for predicting outcome for adult intensive care patients.
To compare the ability of two methods--Acute Physiology and Chronic Health Evaluation (APACHE II) and Mortality Prediction Model (MPM)--to predict hospital outcome for a large group of intensive care patients from Britain and Ireland. ⋯ APACHE II demonstrated a higher degree of overall goodness of fit, which was superior to MPM for groups of intensive care patients from Britain and Ireland.

Multicenter StudyMortality probability models for patients in the intensive care unit for 48 or 72 hours: a prospective, multicenter study.
To develop models in the Mortality Probability Model (MPM II) system to estimate the probability of hospital mortality at 48 and 72 hrs in the intensive care unit (ICU), and to test whether the 24-hr Mortality Probability Model (MPM24), developed for use at 24 hrs in the ICU, can be used on a daily basis beyond 24 hrs. ⋯ Models developed for use among ICU patients at one time period are not transferable without modification to other time periods. The MPM48 and MPM72 calibrated well to their respective time periods, and they are intended for use at specific points in time. The increasing constant terms and associated increase in the probability of hospital mortality exemplify a common clinical adage that if a patient's clinical profile stays the same, he or she is actually getting worse.

Multicenter StudyDaily prognostic estimates for critically ill adults in intensive care units: results from a prospective, multicenter, inception cohort analysis.
To develop daily prognostic estimates for individual patients treated in adult intensive care units (ICU). ⋯ Equations using initial and repeated physiologic measurements provide a high degree of explanatory power for subsequent hospital mortality rate. These daily prognostic estimates deserve evaluation for their potential role in improving the process and outcome from clinical decision-making.

This descriptive study looked at how nurses positioned the critically ill person in the Intensive Care Unit. Its objective was to identify what positions were utilised, and whether severity of illness influenced this choice. ⋯ As the severity of illness increased, more horizontal positions were utilised. These findings and review of the literature highlights a need for further research into specific aspects of the use of position during critical illness.
