RESUMO
BACKGROUND: Enhanced recovery programs (ERP) demonstrated decreased postoperative complication rate and reduced length of stay (LOS). Recently, data on the financial impact revealed cost reduction for colorectal, liver and pancreatic surgery. The present study aimed to assess the cost-effectiveness of ERP in gastric surgery. METHODS: ERP based on enhanced recovery after surgery (ERAS®) society guidelines was implemented in our institution, in June 2014. Consecutive patients undergoing gastric surgery after ERP implementation (n = 71) were compared to a control group of consecutive patients operated before ERP implementation (n = 58). Primary endpoint was cost-effectiveness including detailed perioperative costs. Secondary endpoints were postoperative complications and LOS. Standard statistical testing (means, Mann-Whitney Fisher's exact T test or Pearson Chi-square test) was used. RESULTS: Both groups were comparable regarding demographic details. Mean (SD) overall costs per patient were lower in the ERP group (33,418 (17,901) vs 39,804 (27,288), P = 0.027). Lower costs were found for anesthesia and operating room (-2 356), intensive or intermediate care (-8 629), medication (-1 196)), physiotherapy (-611), laboratory (-1 625)) and blood transfusion (-977). Overall complication rates in ERP and control group (51% vs 62%, P = 0.176) were similar. Mean length of stay (SD) (14(13) days vs 17(11) days, P = 0.037) was shorter in the ERP group. CONCLUSION: ERP significantly reduces overall, preoperative and postoperative costs in patients undergoing major gastric surgery.
