Randomized Controlled Trial
A Human Volunteer Study to Identify Variability in Performance in the Cognitive Domain of the Postoperative Quality of Recovery Scale.
The Postoperative Quality of Recovery Scale found lower than anticipated recovery in the cognitive domain. The definition of cognitive recovery did not allow for performance variability, and may have been too sensitive. This study aimed to examine variability in cognitive performance in volunteers. ⋯ The authors recommend adoption of the new method for scoring cognitive recovery in the Postoperative Quality of Recovery Scale. Telephone or face-to-face delivery was equivalent and either method can be reliably applied.
