Development of the American association of critical-care nurses' sedation assessment scale for critically ill patients.

Abstract

Clinicians commonly sedate critically ill patients. Sedatives should be administered to achieve predetermined end points. Most currently available scales used to assess sedation are inadequate because they focus on a single domain, such as consciousness. The development of the American Association of Critical-Care Nurses' Sedation Assessment Scale is described. This new scale consists of 5 domains: consciousness, agitation, anxiety, sleep, and patient-ventilator synchrony. A major advantage of the scale is that its domains parallel common goals of sedation therapy for critically ill patients. The proposed measurements for each domain are based on a comprehensive evaluation of the science and expert recommendations. Before the scale is widely used, clinical testing is required to determine its validity and reliability in a variety of critically ill patients and care situations.
