The Role of Feedback Training on Early Postoperative Recovery and Anxiety Scores in an Ambulatory Surgical Unit: A Secular Trend Study.

Background: We used a ten-item postoperative quality of recovery score (QoR-10) to assess the perioperative quality of care in an in-hospital ambulatory surgical unit.

Methods: In Phase 1 of this secular trend study (n=300 patients, 3-months duration), we collected QoR-10 scores and potential confounders, including type of anesthesia and surgery; co-morbidities; and anesthesia components of the Amsterdam scale-measured anxiety scores. Phase 2 was the one-month performance feedback learning phase in which modifiable variables identified in Phase 1 were translated to actionable steps, reinforcing the already existing routine of our department's clinical practices, including pain, shivering and anxiety. The anesthesiology team was instructed and reminded of these steps using performance feedback methods. In Phase 3 (n=300 patients, 3-month duration) we evaluated the efficacy of this performance feedback instruction. QoR-10 scores were compared between Phase 1 and Phase 3.

Results: Phase 1 identified three modifiable variables as targets for improvement: postoperative shivering; percentage of patients with numerical rating pain scale (NRS)<4; and preoperative anxiety from anesthesia scores. Compared to Phase 1, significantly fewer Phase 3 patients had severe shivering (2.3% vs. 7.3%, p = 0.023), and a greater percentage had NRS < 4 points (79% vs. 49.7%, p <0.001). The percentage of patients with a high anxiety score did not differ between phases. A direct association between anxiety score and QoR-10 score was not detected. The QoR-10 score (median (IQR)) was significantly higher in Phase 3 than Phase 1: 50 (49-50) vs. 49(49-50), p<0.001. In a multivariable logistic regression analysis, odds for a QoR-10 score of 49-50 were 1.92 higher in Phase 3 than Phase 1.

Conclusion: Considering the study limitations, team feedback education contributed to improvement of the QoR-10 score, reduced the proportion of patients with severe shivering and increased the percentage of patients with low pain scores.
