Enhanced recovery after surgery after radical gastrectomy: Improved compliance over time is associated with a shorter postoperative hospital stay

Abstract

Changing adherence over time to enhanced recovery after surgery (ERAS) protocols following radical gastrectomy and the impact this has on length of stay (LoS) is not well described. This study aimed to explore the changes in adherence to core ERAS elements over time and the relationship between compliance and LoS.A retrospective, single center cohort study was performed between 01/2016–12/2021. An ad hoc analysis revealed the point at which a significant difference in the number of patients being discharge on postoperative day (PoD) 3 was noted allowing allocation of patients to Group A (01/2016–12/2019) or B (01/2020–12/2021). Compliance with core ERAS elements was compared and the relationship between compliance and discharge by (PoD) 3 assessed. Variables significant on univariate analysis were assessed using binary multivariate regression.Of the 268 patients identified, 187 met the inclusion criteria (Group A 112 and Group B 75). More patients in Group B mobilized on PoD 1 (60.0 vs. 31.3%, p = <0.001), tolerated postgastrectomy diet by PoD 3 (84.6 vs. 62.5%, p = 0.049), and were discharged by PoD 3 (34.7 vs. 20.5%, p = 0.002). Protocol compliance of >75% was associated with discharge on PoD 3 (area under the curve, 0.726). Active mobilization on PoD 1 (OR 3.5, p = 0.009), compliance ≥75% (OR 3.3, p = 0.036), and preoperative nutritional consult (OR 0.2, p = 0.002) were independently associated with discharge on PoD 3. Discharge on PoD 3 did not increase readmission or representation to hospital.Early mobilization, protocol compliance >75%, and preoperative nutritional consult were associated with discharge on PoD 3 after radical gastrectomy.
