Thoracic Enhanced Recovery After Surgery: Single Academic Center Observations After Implementation.

BACKGROUND

Enhanced recovery after surgery (ERAS) is an evidence-based, multidisciplinary perioperative care model shown to reduce complications and hospital length of stay (LOS). While some thoracic ERAS studies were inconclusive, others demonstrated that ERAS improves patient outcomes after lung resections and provides more cost-effective care. We aimed to investigate the effects of preliminary implementation of an ERAS protocol, in comparison with conventional care, on lung resection outcomes at a single academic institution.

METHODS

In this observational study, adult patients undergoing lung resections during the pre-ERAS (April 2014 to September 2015) and post-ERAS (January 2016 to May 2017) periods were identified. Relevant demographic, preoperative, anesthesia, and surgical variables were collected. Pre-ERAS and post-ERAS cohorts were compared in terms of hospital LOS, postoperative complications, and 30-day outcomes.

RESULTS

We identified 264 patients, half in each cohort. Pre-ERAS and post-ERAS groups were similar with respect to age, race, and comorbidities. There were no significant differences in LOS, complications, 30-day readmission and mortality rates, or patient-reported outcomes. Of the patients with prolonged LOS, 31% had pulmonary complications, almost half of which were prolonged air leaks. ERAS adherence rate was approximately 60%.

CONCLUSIONS

In the first year of implementation, median LOS, complications, and 30-day outcomes did not differ significantly between the pre-ERAS and post-ERAS groups. Prolonged air leaks commonly led to prolonged LOS; therefore, thoracic ERAS protocols could include interventions to reduce air leak and consideration for discharging patients with chest tubes placed to Heimlich valves. Buy-in and adherence to a new protocol are necessary for implementation to be effective.
