Technology assessment in critical care

Abstract
Critical care services have grown to consume a substantial role in health care with little emphasis on the evaluation of the technologies they routinely employ. Although the appropriate assessment of new technologies is becoming increasingly important, many critical care practitioners remain confused as to the methods of technology assessment. In this review we begin by defining terms commonly used in the technology assessment process. We then undertake a brief discussion of how the benefits of new technologies can be examined. Costs and their calculation are then discussed, followed by a brief discussion of those analyses that combine both costs and consequences. Finally, a framework for helping the individual practitioner evaluate or plan technology assessment protocols is presented.
