Sedation assessment: easier said than done!

Abstract

Sedation assessment commonly is performed in critically ill patients to evaluate their need for, and response to, sedation therapy. Although many sedation assessment scales have been published, few have been tested properly to assure their appropriateness for use in critically ill patients. This article highlights the published sedation assessment scales that have the strongest scientific basis, identifies limitations of the current scales, and suggests characteristics for future sedation assessment scales that would overcome many of the current problems.
