Type of study: Observational cohort (before/after) study
Hypothesis: To examine the effects of implementing a perioperative pathway with regard to anesthesia practices, perioperative patient outcomes, length of stay, and healthcare costs following open liver surgery.
Methods: All patients undergoing liver resections during an 18 month period at a single center were analyzed for outcomes. The new ERAS pathway was initiated during month 6.
Results: The ERAS pathway was associated with a reduction in opioid use, shorter hospital stay, and decreased costs.
Strengths: Prospective, Before/After design helps to eliminate some confounding factors
Weaknesses: Single center, Small sample size, Not randomized, Intraoperative ERAS protocol was unclear
Key Point: An ERAS pathway for liver resections may be associated with reduced opioid use, hospital length of stay, and hospital costs.
