AbstractEffective patient care in the intensive care unit (ICU) depends on the ability of clinicians to process large amounts of clinical and laboratory data. Recently, medical informatics applications have been developed to store and display patient information and assist clinical decision making. Despite the proliferation of these systems and their potential to improve patient care, there are no comprehensive health technology assessments incorporating considerations of safety, functionality, technical performance, clinical effectiveness, economics, and organizational implications. The objectives and methods of informatics evaluations depend on the type of application and the stage of development. Qualitative and quantitative nonrandomized evaluations of comprehensive information management systems like electronic medical records and picture archiving and communications systems should concentrate on technical and functional issues. Specific applications like clinical decision support systems and computerized patient care systems are designed to improve patient outcomes and clinical performance; randomized controlled trials (RCTs) to assess clinical effectiveness are important in their assessment. Although studies of these applications in the ICU setting are increasing, there are currently very few published randomized trials.Copyright 2003 Elsevier, Inc. All rights reserved.
