Development of a clinical definition for acute respiratory distress syndrome using the Delphi technique.
The objective of this study is to describe the implementation of formal consensus techniques in the development of a clinical definition for acute respiratory distress syndrome. ⋯ We conclude that it is feasible to consider using formal consensus in the development of future definitions of acute respiratory distress syndrome. Testing of sensibility, reliability, and validity are needed for this preliminary definition; these test results should be incorporated into future iterations of this definition.

Is regional citrate superior to systemic heparin anticoagulation for continuous renal replacement therapy? A prospective observational study in an adult regional critical care system.
Continuous renal replacement therapy (CRRT) is commonly used in the care of critically ill patients although the optimal means of anticoagulation is not well defined. We report our regional CRRT protocol that was developed using the principles of quality improvement and compare the effect of regional citrate with systemic heparin anticoagulation on filter life span. ⋯ Regional citrate anticoagulation was associated with prolonged filter survival and increased completion of scheduled filter life span compared with heparin. These data support small studies suggesting that citrate is a superior anticoagulant for CRRT and suggest the need for a future definitive randomized controlled trial.

In the past 2 decades, societal spending on health care has become an international concern. The United States currently spends more than 1.6 trillion dollars per year on health care--approximately 15% of the gross domestic product. ⋯ Economic evaluation can aid policy makers and health care professionals in comparing the relative and incremental value of disparate and expensive therapies and also inform decisions about which interventions provide good value for the health care dollar. In this review, we will highlight landmark publications over the past decades that have helped to shape the field of economic evaluations for critical care medicine.
