IAA’s ERAS Protocol Study Published in the JCVA

The first published report to demonstrate a potential benefit of ERAS for patients undergoing urgent or emergency cardiac surgery is now out in print in the January issue of the Journal of Cardiovascular Anesthesia.

“This article reflects a retrospective study conducted at Hartford Hospital that utilized an institutional quality improvement database for the Society of Thoracic Surgery,” stated IAA anesthesiologist Trevor S. Sutton, MD, MBA. “Our team studied 1012 patients who underwent urgent or emergency coronary artery bypass graft surgery at Hartford Hospital between 2016 and 2020. We examined 30-day clinical outcomes, and outcomes related to early mobilization prior to and following implementation of an enhanced recovery after cardiac surgery protocol.” 

The results of this study were astounding and have far-reaching implications for future ERAS protocol implementation. The team found that following enhanced recovery after surgery (ERAS) implementation, the length of stay for patients undergoing urgent or emergency coronary artery bypass graft surgery was reduced by approximately 2 days – without any adverse effects on short-term or 30-day safety or quality metrics.
