The importance of postoperative quality of recovery: influences, assessment, and clinical and prognostic implications.

Quality of recovery is a complex construct whose definition is influenced heavily by the opinions and biases of the individual patient, clinician, or institution. Asa result, recovery assessment tools differ in their fundamental definitions of recovery, breadth, and assessment time frame. Accurate assessment of recovery is essential as suboptimal recovery has both economic and prognostic implications. Quality of care is often substituted as a surrogate at the institutional level for quality of recovery, but it is ideologically distinct from patients' perceived quality of care, recovery, and satisfaction. Recovery tools also differ in their assessment of recovery as a continuous vs dichotomous variable and in their focus at the group vs individual level. Ideally, recovery measures should assess outcomes in a simple dichotomous fashion and maintain relevancy by assessing in multiple domains at various time points. Assessment of recovery in a dichotomous fashion also has both clinical and research applications. It allows identification of suboptimal recovery at both individual and group levels,respectively, and when performed in real time, it allows the opportunity for timely targeted intervention specific to individual patients as well as for resource rationalization.
