Implementation of an Enhanced Recovery After Surgery Program Can Change Nutrition Care Practice: A Multicenter Experience in Elective Colorectal Surgery.

BACKGROUND: Enhanced recovery after surgery (ERAS) programs are multimodal evidenced-based care pathways for optimal recovery. Central to ERAS is integration of perioperative nutrition care into the overall management of the patient. This study describes changes to perioperative nutrition care after implementation of an ERAS program, and identifies factors that affect compliance to ERAS care elements and short-term postoperative outcomes. METHODS: Data were prospectively collected from patients undergoing elective colorectal surgery at 6 hospitals in Alberta, Canada, from 2013-2017. Compliance to nutrition care elements (nutrition risk screening, preoperative carbohydrate loading, early postoperative oral feeding, and mobilization) was recorded before ERAS implementation (pre-ERAS group, n = 487) and with ERAS implementation (ERAS group, n = 3536). Logistic regression identified factors that affect compliance to care elements, length of hospital stay (LOS), and postoperative complications. RESULTS: A total of 4023 patients were included. The rate of nutrition risk screening improved from 9% (pre-ERAS group) to 74% (ERAS group); 12% were at nutrition risk. Compliance increased for preoperative carbohydrate loading (4%-61%), early postoperative oral feeding (P < .001), and mobilization (P < .001). In multivariable logistic regression, nutrition risk independently predicted low overall compliance (<70%) to ERAS care elements (odds ratio [OR] 2.77; 95% CI, 2.11-3.64; P < .001) and a trend for LOS >5 days (OR 1.40; 95% CI, 1.00-1.96; P = .052). Low compliance to ERAS (<70%) predicted postoperative complications (OR 2.69; 95% CI, 2.23-3.24; P < .001). CONCLUSION: ERAS implementation positively impacted the adoption of standardized perioperative nutrition care practices. Nutrition risk screening identified patients less able to comply with postoperative nutrition care elements and who had longer LOS.

(n-3) fatty acids reduce the release of prostaglandin E2 from bone but do not affect bone mass in obese (fa/fa) and lean Zucker rats.

Childhood obesity is prevalent and linked to the development of Type 2 diabetes mellitus (DM) and poor bone health. Some PUFA enhance bone mass and thus may improve bone health in obese children. The study objective was to determine the effects of dietary (n-6) compared with (n-3) essential PUFA and long-chain PUFA (LCPUFA) on bone in an obese and insulin-resistant state. Male fa/fa (n = 48) and lean Zucker rats (n = 48) were fed diets containing safflower oil [SO, high (n-6) PUFA], flaxseed oil [FXO, high (n-3) PUFA], or menhaden oil [MO, high (n-3) LCPUFA] for 9 wk. Measurements included the following: femur bone area (BA), mineral content (BMC), density (BMD), morphometry and ex vivo release of prostaglandin E(2) (PGE(2)); plasma osteocalcin and C-terminal telopeptides of type I collagen. Differences among groups were detected using 2-way ANOVA. Genotype effects in the fa/fa rats included lower femoral weight, length, BA, and BMC, as well as femoral head and proximal epiphysis widths compared with the lean rats, but BMD was not affected. Femur BA, BMC, and BMD did not differ among the dietary groups, but diaphysis width was elevated in the MO group and PGE(2) release was reduced by the FXO and MO diets. No genotype x diet interactions were observed. These data indicate that the fa/fa Zucker rat is at risk for low bone mass and that dietary (n-3) FA effectively reduce PGE(2) release. Whether reduced PGE(2) will support optimal peak bone mass during childhood and conserve bone mass with aging warrants investigation.
