Abstract

Objectives

The aim of this pilot study was to assess feasibility of a perioperative care bundle for enhanced recovery after cardiac surgery (ERACS).
Design

A prospective observational audit.
Setting

A major urban teaching and university hospital and tertiary referral center.
Participants

Patients undergoing cardiac surgery: 53 patients studied before implementation of ERACS (pre-ERACS group) and 52 patients after (ERACS group).
Interventions

Based on recommendations from a consensus review in colorectal surgery, the following enhanced recovery perioperative care bundle was applied: detailed preoperative information, avoidance of prolonged fasting periods preoperatively, preoperative carbohydrate beverages, optimization of analgesia with avoidance of long-acting opioids, prevention of postoperative nausea and vomiting, early enteral nutrition postoperatively, and early mobilization.
Measurements and Main Results

We hypothesized that length of hospital stay would be reduced with ERACS. Secondary outcome variables included a composite of postoperative complications and pain scores.

Whereas the length of stay in the group of patients receiving the bundle of enhanced recovery interventions remained unchanged compared to the non-ERACS group, there was a statistically significant reduction in the number of patients in the ERACS group presenting with one or more postoperative complications (including hospital-acquired infections, acute kidney injury, atrial fibrillation, respiratory failure, postoperative myocardial infarction and death). Additionally, postoperative pain scores were significantly improved in the ERACS group.
Conclusions

This pilot study demonstrates that ERACS is feasible and has the potential for improved postoperative morbidity after cardiac surgery. A larger multi-center quality improvement study implementing perioperative care bundles would be the next step to further assess outcomes in ERACS patients.
