The Enhanced Recovery After Surgery Society guideline for intraoperative care in cesarean delivery will provide best practice, evidenced-based, recommendations for intraoperative care, with primarily ...a maternal focus. The “focused” pathway process for scheduled and unscheduled cesarean delivery for this Enhanced Recovery After Surgery cesarean delivery guideline will consider procedure from the decision to operate (starting with the 30–60 minutes before skin incision) through the surgery. The literature search (1966–2017) used Embase and PubMed to search medical subject headings including “cesarean section,” “cesarean section,” “cesarean section delivery,” and all pre- and intraoperative Enhanced Recovery After Surgery items. Study selection allowed titles and abstracts to be screened by individual reviewers to identify potentially relevant articles. Metaanalyses, systematic reviews, randomized controlled studies, nonrandomized controlled studies, reviews, and case series were considered for each individual topic. Quality assessment and data analyses evaluated the quality of evidence and recommendations were evaluated according to the Grading of Recommendations, Assessment, Development and Evaluation system as used and described in previous Enhanced Recovery After Surgery Society guidelines. The Enhanced Recovery After Surgery cesarean delivery guideline/pathway has created a maternal focused pathway (for scheduled and unscheduled surgery starting from 30–60 minutes before skin incision to maternal discharge) with Enhanced Recovery After Surgery–directed preoperative elements, intraoperative elements, and postoperative elements. Specifics of the intraoperative care included the use of prophylactic antibiotics before the cesarean delivery, appropriate patient warming intraoperatively, blunt expansion of the transverse uterine hysterotomy, skin closure with subcuticular sutures, and delayed cord clamping. A number of specific elements of intraoperative care of women who undergo cesarean delivery are recommended based on the evidence. The Enhanced Recovery After Surgery Society guideline for intraoperative care in cesarean delivery will provide best practice, evidenced-based, recommendations for intraoperative care with primarily a maternal focus. When the cesarean delivery pathway (elements/processes) is studied, implemented, audited, evaluated, and optimized by maternity care teams, this will create an opportunity for the focused and optimized areas of care and recommendations to be further enhanced.
Enhanced recovery pathways have been shown to reduce length of stay without increasing readmission or complications in numerous areas of surgery. Uptake of gynecologic oncology ERAS guidelines has ...been limited. We describe the effect of ERAS guideline implementation in gynecologic oncology on length of stay, patient outcomes, and economic impact for a province-wide single-payer system.
We compared pre- and post-guideline implementation outcomes in consecutive staging and debulking patients at two centers that provide the majority of surgical gynecologic oncology care in Alberta, Canada between March 2016 and April 2017. Clinical outcomes and compliance were obtained using the ERAS Interactive Audit System. Patients were followed until 30 days after discharge. Negative binomial regression was employed to adjust for patient characteristics.
We assessed 152 pre-ERAS and 367 post-ERAS implementation patients. Mean compliance with ERAS care elements increased from 56% to 77.0% after implementation (p < 0.0001). Median length of stay for all surgeries decreased from 4.0 days to 3.0 days post-ERAS (p < 0.0001), which translated to an adjusted LOS decrease of 31.4% (95% CI = 21.7% - 39.9%, p < 0.0001). In medium/high complexity surgery median LOS was reduced by 2.0 days (p = 0.0005). Complications prior to discharge decreased from 53.3% to 36.2% post-ERAS (p = 0.0003). There was no significant difference in readmission (p = 0.6159), complications up to 30 days (p = 0.6274), or mortality (p = 0.3618) between the cohorts. The net cost savings per patient was $956 (95%CI: $162 to $1636).
Systematic implementation of ERAS gynecologic oncology guidelines across a healthcare system improves patient outcomes and saves resources.
•Implementation of ERAS gynecologic oncology guidelines results in significant clinical improvements and cost savings.•Use of an audit system allows measurement of compliance to the individual ERAS recommendations.•ERAS teams should strive to improve compliance to guidelines as this translates into improved outcomes.
BACKGROUND: Poor food intake is common in acute care patients and can exacerbate or develop into malnutrition, influencing both recovery and outcome. Yet, research on barriers and how they can be ...alleviated is lacking. The present study aimed to (i) describe the prevalence of food intake barriers in diverse hospitals and (ii) determine whether patient, care or hospital characteristics are associated with the experience of these barriers. METHODS: Patients (n = 890; 87%) completed a validated questionnaire on barriers to food intake, including perceptions of food quality, just before their discharge from a medical or surgical unit in each of 18 hospitals across Canada. Scores were created for barrier domains. Associations between these barriers and selected patient characteristics collected at admission or throughout the hospital stay and site characteristics were determined using bivariate analyses. RESULTS: Common barriers were being interrupted at meals (41.8%), not being given food when a meal was missed (69.2%), not wanting ordered food (58%), loss of appetite (63.9%) and feeling too sick (42.7%) or tired (41.1%) to eat. Younger patients were more likely (P < 0.0001) to report being disturbed at meals (44.6%) than older patients (33.9%) and missing a meal for tests (39.0% versus 31.0%, P < 0.05). Patients who were malnourished, women, those with more comorbidity, and those who ate <50% of the meal reported several barriers across domains. CONCLUSIONS: The present study confirms that barriers to food intake are common in acute care hospitals. This analysis also identifies that specific patient subgroups are more likely to experience food intake barriers. Because self‐reported low food intake in hospital was associated with several barriers, it is relevant to consider assessing, intervening and monitoring barriers to food intake during the hospital stay.
The role of home parenteral nutrition (HPN) in incurable cachectic cancer patients unable to eat is extremely controversial. The aim of this study is to analyse which factors can influence the ...outcome.
We studied prospectively 414 incurable cachectic (sub)obstructed cancer patients receiving HPN and analysed the association between patient or clinical characteristics and surviving status.
Median weight loss, versus pre-disease and last 6-month period, was 24% and 16%, respectively. Median body mass index was 19.5, median KPS was 60, median life expectancy was 3 months. Mean/median survival was 4.7/3.0 months; 50.0% and 22.9% of patients survived 3 and 6 months, respectively. At the multivariable analysis, the variables significantly associated with 3- and 6-month survival were Glasgow Prognostic Score (GPS) and KPS, and GPS, KPS and tumour spread, respectively. By the aggregation of the significant variables, it was possible to dissect several classes of patients with different survival probabilities.
The outcome of cachectic incurable cancer patients on HPN is not homogeneous. It is possible to identify groups of patients with a ≥6-month survival (possibly longer than that allowed in starvation). The indications for HPN can be modulated on these clinical/biochemical indices.
Patients with colorectal cancer are at risk of malnutrition before surgery. Multimodal prehabilitation (nutrition, exercise, stress reduction) readies patients physically and mentally for their ...operation. However, it is unclear whether extent of malnutrition influences prehabilitation outcomes. We conducted a pooled analysis from five 4-week multimodal prehabilitation trials in colorectal cancer surgery (prehabilitation: n = 195; control: n = 71). Each patient’s nutritional status was evaluated at baseline using the Patient-Generated Subjective Global Assessment (PG-SGA; higher score, greater need for treatment of malnutrition). Functional walking capacity was measured with the 6-minute walk test distance (6MWD) at baseline and before surgery. A multivariable mixed effects logistic regression model evaluated the potential modifying effect of PG-SGA on a clinically meaningful change of ≥19 m in 6MWD before surgery. Multimodal prehabilitation increased the odds by 3.4 times that colorectal cancer patients improved their 6MWD before surgery as compared with control (95% confidence interval (CI): 1.6 to 7.3; P = 0.001, n = 220). Nutritional status significantly modified this outcome (P = 0.007): Neither those patients with PG-SGA ≥9 (adjusted odds ratio: 1.3; 95% CI: 0.23 to 7.2, P = 0.771, n = 39) nor PG-SGA <4 (adjusted odds ratio: 1.3; 95% CI: 0.5 to 3.8, P = 0.574, n = 87) improved in 6MWD with prehabilitation. In conclusion, baseline nutritional status modifies prehabilitation effectiveness before colorectal cancer surgery. Patients with a PG-SGA score 4–8 appear to benefit most (physically) from 4 weeks of multimodal prehabilitation.
Novelty:
Nutritional status is an effect modifier of prehabilitation physical function outcomes.
Patients with a PG-SGA score 4–8 benefited physically from 4 weeks of multimodal prehabilitation.
Nutrition screening should be initiated on hospital admission by non-dietitians. This research aimed to validate and assess the reliability of the Canadian Nutrition Screening Tool (CNST) in the ...'real-world' hospital setting.
Adult patients were admitted to surgical and medical wards only (no palliative patients). Study 1--Nutrition Care in Canadian Hospitals (n=1014): development of the CNST (3 items: weight loss, decrease food intake, body mass index (BMI)) and exploratory assessment of its criterion and predictive validity. Study 2--Inter-rater reliability and criterion validity assessment of the tool completed by untrained nursing personnel or diet technician (DT) (n=150). Subjective Global Assessment performed by site coordinators was used as a gold standard for comparison.
Study 1: The CNST completed by site coordinators showed good sensitivity (91.7%) and specificity (74.8%). Study 2: In the subsample of untrained personnel (160 nurses; one DT), tool's reliability was excellent (Kappa=0.88), sensitivity was good (>90%) but specificity was low (47.8%). However, using a two-item ('yes' on both weight change and food intake) version of the tool improved the specificity (85.9%). BMI was thus removed to promote feasibility. The final two-item tool (study 1 sample) has a good predictive validity: length of stay (P<0.001), 30-day readmission (P=0.02; X(2) 5.92) and mortality (P<0.001).
The simple and reliable CNST shows good sensitivity and specificity and significantly predicts adverse outcomes. Completion by several untrained nursing personnel confirms its utility in the nursing admission assessment.
This study was conducted to develop evidence-based clinical practice guidelines for nutrition support (ie, enteral and parenteral nutrition) in mechanically ventilated critically ill adults.
The ...following interventions were systematically reviewed for inclusion in the guidelines: enteral nutrition (EN) versus parenteral nutrition (PN), early versus late EN, dose of EN, composition of EN (protein, carbohydrates, lipids, immune-enhancing additives), strategies to optimize delivery of EN and minimize risks (ie, rate of advancement, checking residuals, use of bedside algorithms, motility agents, small bowel versus gastric feedings, elevation of the head of the bed, closed delivery systems, probiotics, bolus administration), enteral nutrition in combination with supplemental PN, use of PN versus standard care in patients with an intact gastrointestinal tract, dose of PN and composition of PN (protein, carbohydrates, IV lipids, additives, vitamins, trace elements, immune enhancing substances), and the use of intensive insulin therapy.
The outcomes considered were mortality (intensive care unit ICU, hospital, and long-term), length of stay (ICU and hospital), quality of life, and specific complications.
We systematically searched MEDLINE and CINAHL (cumulative index to nursing and allied health), EMBASE, and the Cochrane Library for randomized controlled trials and meta-analyses of randomized controlled trials that evaluated any form of nutrition support in critically ill adults. We also searched reference lists and personal files, considering all articles published or unpublished available by August 2002. Each included study was critically appraised in duplicate using a standard scoring system.
For each intervention, we considered the validity of the randomized trials or meta-analyses, the effect size and its associated confidence intervals, the homogeneity of trial results, safety, feasibility, and the economic consequences. The context for discussion was mechanically ventilated patients in Canadian ICUs.
The major potential benefit from implementing these guidelines is improved clinical outcomes of critically ill patients (reduced mortality and ICU stay). Potential harms of implementing these guidelines include increased complications and costs related to the suggested interventions. SUMMARIES OF EVIDENCE AND RECOMMENDATIONS: When considering nutrition support in critically ill patients, we strongly recommend that EN be used in preference to PN. We recommend the use of a standard, polymeric enteral formula that is initiated within 24 to 48 hours after admission to ICU, that patients be cared for in the semirecumbent position, and that arginine-containing enteral products not be used. Strategies to optimize delivery of EN (starting at the target rate, use of a feeding protocol using a higher threshold of gastric residuals volumes, use of motility agents, and use of small bowel feeding) and minimize the risks of EN (elevation of the head of the bed) should be considered. Use of products with fish oils, borage oils, and antioxidants should be considered for patients with acute respiratory distress syndrome. A glutamine-enriched formula should be considered for patients with severe burns and trauma. When initiating EN, we strongly recommend that PN not be used in combination with EN. When PN is used, we recommend that it be supplemented with glutamine, where available. Strategies that maximize the benefit and minimize the risks of PN (hypocaloric dose, withholding lipids, and the use of intensive insulin therapy to achieve tight glycemic control) should be considered. There are insufficient data to generate recommendations in the following areas: use of indirect calorimetry; optimal pH of EN; supplementation with trace elements, antioxidants, or fiber; optimal mix of fats and carbohydrates; use of closed feeding systems; continuous versus bolus feedings; use of probiotics; type of lipids; and mode of lipid delivery.

BCR-ABL oncoprotein-expressing cells are associated with a relative increase of intracellular reactive oxygen species (ROS), which is thought to play a role in transformation. Elevated ROS levels in ...BCR-ABL-transformed cells were found to be blocked by the mitochondrial complex I inhibitor rotenone as well as the glucose transport inhibitor phloretin, suggesting that the source of increased ROS might be related to increased glucose metabolism. The glucose analog 2-deoxyglucose (2-DOG) reduced ROS to levels found in non-BCR-ABL-transformed cells and inhibited cell growth alone or in cooperation with imatinib mesylate (Gleevec). A mutant of BCR-ABL that is defective in transformation of myeloid cells, Tyr177Phe, was also found to be defective in raising intracellular ROS levels. Glucose metabolism in BCR-ABL-transformed cells is likely to be mediated by activation of the phosphatidylinositol-3′-kinase (PI3K) pathway, which is regulated through this site. Inhibition of PI3K or mTOR led to a significant decrease in ROS levels. Overall, our results suggest that elevated levels of ROS in BCR-ABL-transformed cells are secondary to a transformation-associated increase in glucose metabolism and an overactive mitochondrial electron transport chain and is specifically regulated by PI3K. Finally, these results hint at novel targets for drug development that may aid traditional therapy. (Blood. 2005; 105:1717-1723)
The Enhanced Recovery After Surgery (eras) colorectal guideline has been implemented widely across Alberta. Our study examined the clinical and cost impacts of eras on colon cancer patients across ...the province.
We first used both summary statistics and multivariate regression methods to compare, before and after guideline implementation, clinical outcomes (length of stay, complications, readmissions) in consecutive elective colorectal patients 18 or more years of age and in colon cancer and non-cancer patients treated at the Peter Lougheed Centre and the Grey Nuns Hospital between February 2013 and December 2014. We then used the differences in clinical outcomes for colon cancer patients, together with the average cost per hospital day, to estimate cost impacts.
The analysis considered 790 patients (398 cancer and 392 non-cancer patients). Mean guideline compliance increased to 60% in cancer patients and 57% in non-cancer patients after eras implementation from 37% overall before eras implementation. From pre- to post-eras, mean length of stay declined to 8.4 ± 5 days from 9.5 ± 7 days in cancer patients, and to 6.4 ± 4 days from 8.8 ± 5.5 days in non-cancer patients (p = 0.0012 and p = 0.0041 respectively). Complications declined significantly in the renal, hepatic, pancreatic, and gastrointestinal groups (difference in proportions: 13% in cancer patients; p < 0.05). No significant change in the risk of readmission was observed. The net cost savings attributable to eras implementation ranged from $1,096 to $2,771 per cancer patient and from $3,388 to $7,103 per non-cancer patient.
Implementation of eras not only resulted in clinical outcome improvements, but also had a significant beneficial impact on scarce health system resources. The effect for cancer patients was different from that for non-cancer patients, representing an opportunity for further refinement and study.
Summary
Background
Malnutrition is a common and clinically significant problem in patients with cirrhosis. The impact of nutritional therapy remains unclear.
Aim
To provide an up‐to‐date systematic ...review and meta‐analysis of RCTs of oral or enteral nutritional supplementation (ONS or ENS) on nutritional and clinical outcomes in adult patients with cirrhosis.
Methods
The primary outcome measure was survival. Included: full‐text English language RCTs investigating ONS or ENS vs. a standard nonsupplemented diet in patients with cirrhosis. Excluded: parenteral or branched chain amino acids intervention; treatment duration ≤7 days, exclusive evaluation of posttransplant, postsurgical or quality of life outcomes.
Results
Six trials (4 ONS/2 ENS) and 470 patients were included with 71% males and median age 53 years. When all studies were combined, there was no reduction in mortality Relative risk (RR): 0.75 (0.42, 1.32), P = 0.31. Subgroup analysis of 3 of the 4 ONS studies did demonstrate a mortality reduction RR: 0.40 (0.18, 0.90), P = 0.03. Of the 2 ENS studies, one included the sickest patients in the meta‐analysis (82% Child Pugh C) and the other had the shortest mean intervention duration (8.6 days), possibly impacting the potential for benefit. Study quality was suboptimal (median Jadad = 2).
Conclusions
Although there is insufficient evidence to definitively state that oro‐enteral nutritional supplementation impacts clinical outcomes, on the basis of this analysis, one can be cautiously optimistic that there is the potential for benefit without an increase in adverse events. Adequately powered, Child Pugh stratified studies of at least 1 month in duration are needed to clarify the impact on relevant clinical outcomes.
