Impact of Enhanced Recovery Program after Surgery in Patients Undergoing Pancreatectomy on Postoperative Outcomes: A Controlled before and after Study.

BACKGROUND

Implementation of enhanced recovery after surgery (ERAS) program after pancreatic surgery was associated with decreased length of stay (LOS). However, there were only retrospective uncontrolled before-after study, and care protocols were heterogeneous. We aimed to evaluate the impact of ERAS program on postoperative outcomes after pancreatectomy through a prospective controlled study.

METHODS

A before/after study with a contemporary control group was undertaken in patients undergoing pancreatectomy. We compared 2 groups: the intervention hospital that implemented ERAS program and the control hospital that performed traditional care; and 2 periods: the preimplementation and the post-implementation period. A difference-in-differences approach was used to evaluate whether implementation of ERAS program was associated with improved LOS and postoperative morbidity.

RESULTS

About 97 and 75 patients were included in intervention and control hospital. In multivariate analysis, implementation of ERAS was associated with a significantly shorten LOS (hazard ratio 1.61; 95% CI 1.07-2.44) and higher compliance rate (OR 1.34; 95% CI 1.18-1.53). Difference-in-differences analysis revealed that LOS, morbidity, and readmission did not differ after ERAS implementation.

CONCLUSION

Implementation of ERAS program was safe and effective after pancreatectomy with high compliance rate. LOS was significantly reduced without compromising morbidity.
