Observational Study
Enhanced recovery after surgery components and perioperative outcomes: a nationwide observational study.
Enhanced recovery after surgery (ERAS) protocols have been shown to benefit recovery after several operations. However, large-scale data on the association between the level of ERAS use and perioperative complications are scarce, particularly in surgeries with increasing ERAS uptake, including total hip (THA) and knee arthroplasty (TKA). Using US national data, we examined the relationship between the number of ERAS components implemented ('level') and perioperative outcomes. ⋯ ERAS components were used more frequently over time, and the level of utilisation was independently associated with incrementally improved complication odds and reduced length of stay during the primary admission. Possible indication bias limits the certainty of these findings.
