Structured synchronous implementation of an enhanced recovery program in elective colonic surgery in 33 hospitals in The Netherlands

A novel artificial intelligence framework to quantify the impact of clinical compared with nonclinical influences on postoperative length of stay

BACKGROUND

The relative proportion of clinical compared with nonclinical influences on length of stay after colectomy has never been measured. We developed a novel machine-learning framework that quantifies the proportion of length of stay after colectomy attributable to clinical factors and infers the overall impact of nonclinical influences.

STUDY DESIGN

Patients who underwent partial colectomy, total colectomy, or low anterior resection included in American College of Surgeons National Surgical Quality Improvement were analyzed. Multivariable linear regression, random forest, and neural network models were developed to assess the impact of 56 clinical variables on length of stay. The random forest and neural network models were fine-tuned to maximize the explanatory power of clinical variables on length of stay. R2 measured the proportion of length of stay explained by clinical factors. The contribution of nonclinical factors was inferred from residual analysis. Mean absolute error was used to measure the discrepancy between actual and model-predicted length of stay.

RESULTS

Of 96,081 patients, 71% underwent partial colectomy (mean length of stay, 6.8 days; standard deviation, 5.6), 27% low anterior resection (5.4; 4.4), and 2% total colectomy (11.8; 7.1). Clinical factors in multivariable linear regression models accounted for only 29-54% of length of stay variability. The random forest and neural network models demonstrated persistent unexplained length of stay variability even when considering nonlinear interactions (R2: random forest [range, 0.46-0.55]; neural network [range, 0.44-0.57]), consistent with multivariable linear regression models. Mean absolute error showed clinical factors could not account for 2-2.5 days of length of stay after low anterior resection and partial colectomy, and 4 days after total colectomy.

CONCLUSION

This is the first study to quantify the overall influence of clinical factors on post-colectomy length of stay, revealing they explain less than 55% of variability. By maximizing clinical factors' explanatory impact using machine learning, the remaining variability is inferred to be nonclinical. Our findings provide hospitals with a novel paradigm to indirectly measure the influence of previously elusive nonclinical factors.

Real-life effectiveness of prehabilitation to improve postoperative outcomes in patients with colorectal cancer approaching surgery: A systematic review and meta-analyses of observational studies versus randomized controlled trials

INTRODUCTION

Current evidence synthesis of prehabilitation studies in colorectal surgery is based on results of randomized controlled trials (RCT). Although RCTs are the gold standard for effectiveness research, observational studies probably better reflect real-life practice. The aims of the current study were to compare observational studies to RCTs regarding the association between prehabilitation and postoperative outcomes, and characteristics of included patients and interventions.

METHODS

A systematic search was conducted in PubMed, Embase, and CINAHL (until September 2023). Observational studies and RCTs investigating prehabilitation before colorectal surgery and reporting postoperative complications and/or length of stay (LoS) were included. Two reviewers independently assessed the risk of bias using the Cochrane Risk of Bias 2 tool for RCTs and the Cochrane ROBINS-I tool for observational studies. Meta(regression)-analyses were performed for postoperative complications and LoS.

RESULTS

Pooled results showed a statistically significant reduction in postoperative complications (OR 0.54; 95 % confidence interval (CI) 0.40 to 0.72) and LoS (mean difference (MD) -1.34 CI -2.57 to -0.12) after prehabilitation in observational studies but not in RCTs (complications OR 0.95; CI 0.53 to 1.72; LoS MD 0.16 CI -0.52 to 0.83). Patients included in observational studies were older and more often had an ASA score ≥3. In a meta-regression analysis, these characteristics were not statistically significantly associated with the main outcomes.

CONCLUSION

Observational studies in a real-life setting showed that prehabilitation can reduce postoperative complications and LoS. To further explore the real-life effectiveness of prehabilitation, specific observational study designs, like a target emulation trial could be used.

Adherence to enhanced recovery after surgery (ERAS) in older adults following colorectal resection

INTRODUCTION

Enhanced recovery after surgery (ERAS) is an established pathway to improve short-term outcomes in colorectal surgery. It is unclear whether the efficacy, feasibility, and safety of the ERAS protocol are similar in older and younger patients. The study examined adherence to the ERAS protocol and identified factors leading to deviations in older patients.

MATERIALS AND METHODS

Patients undergoing colorectal resection were prospectively included in the ERAS protocol between 2019 and 2022. The cohort was stratified according to age and ERAS adherence score. The patients were compared regarding clinical short-term follow-up (30 days). Univariate and multivariate analyses were performed using the statistical program R (version 4.1.2).

RESULTS

During the study period, 414 patients were recruited, including 132 patients (31.9 %) aged ≥75 years. The cohort of older adults showed significantly higher American Society of Anesthesiologists (ASA) scores III/IV (57.8 % vs. 81.8 %; p < 0.001) and more frequently malignant diseases (45.9 % vs. 64.1 %; p < 0.001), but a lower body mass index (26.7 vs. 24.4; p < 0.001). Furthermore, older adults achieved significantly lower adherence to the ERAS protocol in the postoperative phase (84.6 % vs. 80.1 %; p = 0.003) and experienced a longer median length of hospital stay (6 vs. 8 days; p < 0.001). The differences identified were increased change of body weight on postoperative day 1, delayed removal of a urinary catheter, and shorter duration of mobilization on postoperative days 2 and 3 (p < 0.05). However, in the multivariate analysis, emergency and open surgery as well as severe complications, but not age, were elicited as independent predictive factors for lower adherence to the ERAS protocol postoperatively.

DISCUSSION

Adherence to the postoperative ERAS requirements appears to be lower in older patients, although age alone was not an independent factor in our multivariate analysis and therefore not responsible for a lower adherence to the postoperative ERAS protocol after colorectal resection. This difference underlines the importance of interdisciplinary teamwork in daily practice to achieve optimal postoperative results, especially in older adults.

Short-term morbidity and mortality after right hemicolectomy: an update of national performance in the Netherlands

AIM

The purpose of this Dutch retrospective population-based study was to evaluate how short-term outcomes and inter-hospital variability after right hemicolectomy for colon cancer have evolved between 2012 and 2020.

METHOD

Patients who underwent right hemicolectomy for primary solitary colon cancer between 1 January 2012 and 31 December 2020 and were registered in the Dutch Colorectal Audit were included. Surgical characteristics and outcomes were assessed during three time periods (2012-2014, 2015-2017, 2018-2020). Complications and mortality were the primary outcomes, and reintervention, readmission and length of stay secondary outcomes.

RESULTS

In total, 29 274 patients were included. Significant increase in minimally invasive surgery (51.1% 2012-2014, 73.2% 2015-2017, 85.0% 2018-2020), increase in conversion (6.6%, 7.8%, 9.1%, P < 0.001) and decrease in acute/urgent resections (15.9%, 11.7%, 10.9%, P < 0.001) were found. The overall complication rate was slightly lower in the third period (30.9%, 30.6%, 28.8%, P = 0.004), primarily because of decreasing non-surgical complications (19.7%, 20.6%, 17.6%, P < 0.001), while surgical complications remained unchanged (17.5%, 18.3%, 18.2%, P = 0.277). Postoperative mortality was 3.4%, 2.3% and 3.5%, respectively. Reintervention rate slightly decreased (9.4%, 8.3%, 8.6%, P < 0.001). The proportion of patients admitted for more than 6 days decreased over time (54.3%, 42.4%, 34.3%, P < 0.001), with an increase in readmission rate (7.4%, 6.8%, 9.3%, P < 0.001). Inter-hospital variability decreased over time for complications, length of stay and conversion.

CONCLUSION

This study shows a national decreasing inter-hospital variability in clinical outcomes after right hemicolectomy and a decrease in postoperative complications. Despite increasing use of laparoscopy, surgical complications and mortality remained stable over time.

Feasibility of the ERAS (Enhanced Recovery After Surgery) Protocol in Patients Undergoing Gastrointestinal Cancer Surgeries in a Tertiary Care Hospital-A Prospective Interventional Study

Enhanced Recovery After Surgery (ERAS) protocols have emerged as a promising approach to optimize perioperative care and improve outcomes in various surgical specialties. Despite feasibility studies on ERAS in various surgeries, there remains a paucity of research focusing on gastrointestinal cancer surgeries in the Indian context. The primary objective is to evaluate the compliance rate of the ERAS protocol and secondary objectives include the compliance rate of individual components of the protocol, the complications, the length of hospital stay, and the challenges faced during implementation in patients undergoing gastrointestinal cancer surgeries in our tertiary care cancer center. In this prospective interventional study (CTRI/2022/04/041657; registered on 05/04/2022), we evaluated 50 patients aged 18 to 70 years undergoing surgery for gastrointestinal malignancies and implemented a refined ERAS protocol tailored to our institutional resources and conditions based on standard ERAS society recommendations for gastrointestinal surgeries and specific recommendations for colorectal, pancreatic, and esophageal surgeries.Our study's mean overall compliance rate with the ERAS protocol was 88.54%. We achieved a compliance rate of 91.98%, 81.66%, and 92.00% for pre-operative, intraoperative, and post-operative components respectively. Fourteen (28%) patients experienced complications during the study. The median length of stay was 6.5 days (5.25-8). Challenges were encountered during the preoperative, intraoperative, and postoperative phases. The study highlighted the feasibility of implementing the ERAS protocol in a cancer institute, but specific challenges need to be addressed for its optimal success in gastrointestinal cancer surgeries.

Evolution of enhanced recovery for children undergoing elective intestinal surgery

Enhanced recovery protocols (ERP) have been widely adopted in adult populations, with over 30 years of experience demonstrating the effectiveness of these protocols in patients undergoing gastrointestinal (GI) surgery. In the last decade, ERPs have been applied to pediatric populations across multiple subspecialties. The objective of this manuscript is to explore the evolution of how ERPs have been implemented and adapted specifically for pediatric populations undergoing GI surgery, predominantly for inflammatory bowel disease. The reported findings reflect a thorough exploration of the literature, including initial surveys of practice/readiness assessments, consensus recommendations of expert panels, and data from a rapidly growing number of single center studies. These efforts have culminated in a national prospective, multicenter trial evaluating clinical and implementation outcomes for enhanced recovery in children undergoing GI surgery. In short, this historical and clinical review reflects on the evolution of ERPs in pediatric surgery and expounds upon the next steps needed to apply ERPs to future pediatric populations.

Colonoscopic-assisted laparoscopic wedge resection versus segmental colon resection for benign colonic polyps: a comparative cost analysis

AIM

The colonoscopic-assisted laparoscopic wedge resection (CAL-WR) is proven to be an effective and safe alternative to a segmental colon resection (SCR) for large or complex benign colonic polyps that are not eligible for endoscopic removal. This analysis aimed to evaluate the costs of CAL-WR and compare them to the costs of an SCR.

METHOD

A single-centre 90-day 'in-hospital' comparative cost analysis was performed on patients undergoing CAL-WR or SCR for complex benign polyps between 2016 and 2020. The CAL-WR group consisted of 44 patients who participated in a prospective multicentre study (LIMERIC study). Inclusion criteria were (1) endoscopically unresectable benign polyps; (2) residual or recurrence after previous polypectomy; or (3) irradically resected low risk pT1 colon carcinoma. The comparison group, which was retrospectively identified, included 32 patients who underwent an elective SCR in the same period.

RESULTS

Colonoscopic-assisted laparoscopic wedge resection was associated with significantly fewer complications (7% in the CAL-WR group vs. 45% in the SCR group, P < 0.001), shorter operation time (50 min in the CAL-WR group vs. 119 min in the SCR group, P < 0.001), shorter length of hospital stay (median length of stay 2 days in the CAL-WR group vs. 4 days in the SCR group, P < 0.001) and less use of surgical resources (reduction in costs of 32% per patient), resulting in a cost savings of €2372 (£2099 GBP) per patient (P < 0.001).

CONCLUSION

Given the clinical and financial benefits, CAL-WR should be recommended for complex benign polyps that are not eligible for endoscopic resection before major surgery is considered.

High adherence to enhanced recovery pathway independently reduces major morbidity and mortality rates after colorectal surgery: a reappraisal of the iCral2 and iCral3 multicenter prospective studies

Background:

Enhanced recovery after surgery (ERAS) offers lower overall morbidity rates and shorter hospital stay after colorectal surgery (CRS); high adherence rates to ERAS may significantly reduce major morbidity (MM), anastomotic leakage (AL), and mortality (M) rates as well.

Methods:

Prospective enrollment of patients submitted to elective CRS with anastomosis in two separate 18- and 12-month periods among 78 surgical centers in Italy from 2019 to 2021. Adherence to ERAS pathway items was measured upon explicit criteria in every case. After univariate analysis, independent predictors of primary endpoints (MM, AL, and M rates) were identified through logistic regression analyses, presenting odds ratios (OR) and 95% confidence intervals.

Results:

An institutional ERAS status was declared by 48 out of 78 (61.5%) participating centers. The median overall adherence to ERAS was 75%. Among 8,359 patients included in both studies, MM, AL, and M rates were 6.3%, 4.4%, and 1.0%, respectively. Several patient-related and treatment-related variables showed independently higher rates for primary endpoints: male gender, American Society of Anesthesiologists class III, neoadjuvant treatment, perioperative steroids, intra- and/or postoperative blood transfusions, length of the operation >180’, surgery for malignancy. On the other hand, ERAS adherence >85% independently reduced MM (OR, 0.91) and M (OR, 0.25) rates, whereas no mechanical bowel preparation independently reduced AL (OR, 0.68) rates.

Conclusions:

Among other patient- or treatment-related variables, ERAS adherence >85% independently reduced MM and M rates, whereas no mechanical bowel preparation independently reduced AL rates after CRS.

Enhanced Recovery After Surgery and Elderly Patients

Enhanced recovery after surgery (ERAS) is a new way of working where evidence-based care elements are assembled to form a care pathway involving the patient's entire journey through surgery. Many elements included in ERAS have stress-reducing effects on the body or helps avoid side effects associated with alternative treatment options. This leads to less overall stress from the injury caused by the operation and helps facilitate recovery. In old, frail patients with concomitant diseases and less physical reserves, this may help explain why the ERAS care is reported to be beneficial for this specific patient group.

Creating Value Through Learning Health Systems: The Alberta Strategic Clinical Network Experience

Design, implementation, and evaluation of effective multicomponent interventions typically take decades before value is realized even when value can be measured. Value-based health care, an approach to improving patient and health system outcomes, is a way of organizing health systems to transform outcomes and achieve the highest quality of care and the best possible outcomes with the lowest cost. We describe 2 case studies of value-based health care optimized through a learning health system framework that includes Strategic Clinical Networks. Both cases demonstrate the acceleration of evidence to practice through scientific, financial, structural administrative supports and partnerships. Clinical practice interventions in both cases, one in perioperative services and the other in neonatal intensive care, were implemented across multiple hospital sites. The practical application of using an innovation pipeline as a structural process is described and applied to these cases. A value for money improvement calculator using a benefits realization approach is presented as a mechanism/tool for attributing value to improvement initiatives that takes advantage of available system data, customizing and making the data usable for frontline managers and decision makers. Health care leaders will find value in the descriptions and practical information provided.

Enhanced Recovery Protocols Reduce Mortality Across Eight Surgical Specialties at Academic and University-affiliated Community Hospitals

OBJECTIVE

To determine if implementation of a simplified ERP across multiple surgical specialties in different hospitals is associated with improved short and long-term mortality. Secondary aims were to examine ERP effect on length of stay, 30-day readmission, discharge disposition, and complications.

SUMMARY BACKGROUND DATA

Enhanced recovery after surgery and various derivative ERPs have been successfully implemented. These protocols typically include elaborate sets of multimodal and multidisciplinary approaches, which can make implementation challenging or are variable across different specialties. Few studies have shown if a simplified version of ERP implemented across multiple surgical specialties can improve clinical outcomes.

METHODS

A simplified ERP with 7 key domains (minimally invasive surgical approach when feasible, pre-/intra-operative multimodal analgesia, postoperative multimodal analgesia, postoperative nausea and vomiting prophylaxis, early diet advancement, early ambulation, and early removal of urinary catheter) was implemented in 5 academic and community hospitals within a single health system. Patients who underwent nonemergent, major orthopedic or abdominal surgery including hip/knee replacement, hepatobiliary, colorectal, gynecology oncology, bariatric, general, and urological surgery were included. Propensity-matched, retrospective case-control analysis was performed on all eligible surgical patients between 2014 and 2017 after ERP implementation or in the 12 months preceding ERP implementation (control population).

RESULTS

A total of 9492 patients (5185 ERP and 4307 controls) underwent ERP eligible surgery during the study period. Three thousand three hundred sixty-seven ERP patients were matched by surgical specialty and hospital site to control non-ERP patients. Short and long-term mortality was improved in ERP patients: 30 day: ERP 0.2% versus control 0.6% ( P = 0.002); 1-year: ERP 3.9% versus control 5.1% ( P < 0.0001); 2-year: ERP 6.2% versus control 9.0% ( P < 0.0001). Length of stay was significantly lower in ERP patients (ERP: 3.9 ± 3.8 days; control: 4.8 ± 5.0 days, P < 0.0001). ERP patients were also less likely to be discharged to a facility (ERP: 11.3%; control: 14.8%, P < 0.0001). There was no significant difference for 30-day readmission. All complications except venous thromboembolism were significantly reduced in the ERP population (P < 0.02).

CONCLUSIONS

A simplified ERP can uniformly be implemented across multiple surgical specialties and hospital types. ERPs improve short and long-term mortality, clinical outcomes, length of stay, and discharge disposition to home.

The Enhanced Recovery after Surgery (ERAS) Pathway Is a Safe Journey for Kidney Transplant Recipients during the "Extended Criteria Donor" Era

Enhanced recovery after surgery (ERAS) protocols are still underused in kidney transplantation (KT) due to recipients’ “frailty” and risk of postoperative complications. We aimed to evaluate the feasibility and safety of ERAS in KT during the “extended-criteria donor” era, and to identify the predictive factors of prolonged hospitalization. In 2010−2019, all patients receiving KT were included in ERAS program targeting a discharge home within 5 days of surgery. Recipient, transplant, and outcomes data were analyzed. Of 454 KT [male: 280, 63.9%; age: 57 (19−77) years], 212 (46.7%) recipients were discharged within the ERAS target (≤5 days), while 242 (53.3%) were discharged later. Patients within the ERAS target (≤5 days) had comparable recipient and transplant characteristics to those with longer hospital stays, and they had similar post-operative complications, readmission rates, and 5 year graft/patient survival. In the multivariate analysis, DGF (HR: 2.16, 95% CI: 1.08−4.34, p < 0.030) and in-hospital dialysis (HR: 3.68, 95% CI: 1.73−7.85, p < 0.001) were the only predictive factors for late discharge. The ERAS approach is feasible and safe in all KT candidates, and its failure is primarily related to the postoperative graft function, rather than the recipient’s clinical status. ERAS pathways, integrated with strict collaboration with local nephrologists, allow early discharge after KT, with clinical benefits.

Principles of enhanced recovery in gastrointestinal surgery

BACKGROUND

To reduce the impact of surgery-related stress, enhanced recovery after surgery (ERAS) pathways have been developed since over 15 years with subsequent improved postoperative outcome. This multimodal and evidence-based perioperative approach has spread to all fields of gastrointestinal surgery, from esophagus, stomach, duodenum and pancreas, liver, small intestine and colon, and rectum, as well as for other specialties like vascular and cardia surgeries or neurosurgery, among others.

PURPOSE

The aim of this state-of-the-art article is to assess current state of evidence on perioperative management specifically in gastrointestinal surgery, with a focus on surgery-related aspects, outcome benefit, and future directions.

CONCLUSION

The surgical team must promote continuous improvement of the patient's ERAS compliance to ensure optimal perioperative care. Everyday clinical practice should be performed according to latest evidence-based medicine and challenging surgical dogma. Moreover, the surgeon must lead and support a multidisciplinary and collaborative teamwork tailored to patient's need especially with anesthetists and nursing staff.

Enhanced recovery in elderly patients undergoing pancreatic resection: A retrospective monocentric study

Enhanced recovery after surgery (ERAS) pathway for pancreas has demonstrated its value in clinical practice. However, there is a lack of specific evidence about its application in elderly patients. The aim of the present study was to assess the impact of age on compliance and postoperative outcomes. Patients ≥70 years old that underwent pancreatic resection within an ERAS pathway between 2012 and 2018 were included, and divided into three groups: 70-74, 75-79, and ≥80 years old. Compliance with ERAS items, length of stay, mortality, and complications were analyzed. 114 patients were included: 49, 37, and 28 patients aged 70-74, 75-79, and ≥80 years, respectively. Overall compliance to ERAS items between groups was not different (66%, 66%, and 62%, P = .201). No significant difference was observed in terms of median length of stay (14, 17, and 17 days, P = .717), overall complications (67%, 78%, and 71%, P = .529), major complications (26%, 32%, and 39%, P = .507), or mortality (0%, 3%, and 4%, P = .448) with increasing age. Application of an ERAS pathway is feasible in elderly patients with pancreatic resection. Increasing age was neither associated with poorer compliance nor worse postoperative outcomes.

ERAS program adherence-institutionalization, major morbidity and anastomotic leakage after elective colorectal surgery: the iCral2 multicenter prospective study

BACKGROUND

Enhanced recovery after surgery (ERAS) programs influence morbidity rates and length of stay after colorectal surgery (CRS), and may also impact major complications and anastomotic leakage rates. A prospective multicenter observational study to investigate the interactions between ERAS program adherence and early outcomes after elective CRS was carried out.

METHODS

Prospective enrolment of patients submitted to elective CRS with anastomosis in 18 months. Adherence to 21 items of ERAS program was measured upon explicit criteria in every case. After univariate analysis, independent predictors of primary endpoints [major morbidity (MM) and anastomotic leakage (AL) rates] were identified through logistic regression analyses including all significant variables, presenting odds ratios (OR).

RESULTS

Institutional ERAS protocol was declared by 27 out of 38 (71.0%) participating centers. Median overall adherence to ERAS program items was 71.4%. Among 3830 patients included in the study, MM and AL rates were 4.7% and 4.2%, respectively. MM rates were independently influenced by intra- and/or postoperative blood transfusions (OR 7.79, 95% CI 5.46-11.10; p < 0.0001) and standard anesthesia protocol (OR 0.68, 95% CI 0.48-0.96; p = 0.028). AL rates were independently influenced by male gender (OR 1.48, 95% CI 1.06-2.07; p = 0.021), intra- and/or postoperative blood transfusions (OR 4.29, 95% CI 2.93-6.50; p < 0.0001) and non-standard resections (OR 1.49, 95% CI 1.01-2.22; p = 0.049).

CONCLUSIONS

This study disclosed wide room for improvement in compliance to several ERAS program items. It failed to detect any significant association between institutionalization and/or adherence rates to ERAS program with primary endpoints. These outcomes were independently influenced by gender, intra- and postoperative blood transfusions, non-standard resections, and standard anesthesia protocol.

Association between compliance with enhanced recovery after surgery (ERAS) protocols and postoperative outcome in patients with primary liver cancer undergoing hepatic resection

Background

Enhanced recovery after surgery (ERAS) is a multidisciplinary, stress-minimizing approach that is associated with improved postoperative outcomes. However, whether the level of compliance with ERAS protocols impacts the postoperative outcome of patients with primary liver cancer undergoing liver resection is unknown. The study aimed to analyze the association between compliance with ERAS protocols and liver resection outcomes.

Methods

This prospective cohort study consecutively recruited patients with primary liver cancer who were scheduled for elective liver surgery between January 2019 and December 2020 at the Department of Biliary Surgery, West China Hospital of Sichuan University. Twenty individual ERAS items were assessed in all patients. The patients were divided into two groups according to their degree of compliance with the ERAS interventions: an ERAS-compliant (ERAS-C) group of individuals who complied with over 75% of the ERAS components and an ERAS-noncompliant (ERAS-N) group. The primary outcomes were ERAS compliance, occurrence of major complications within 30 days postoperatively, and length of postoperative hospital stay. The secondary outcomes were 30-day readmissions, reoperations and other rehabilitation indicators. The study was registered at www.chictr.org.cn (identity number ChiCTR2000040021).

Results

Overall, 436 patients were enrolled; their mean age was 54 years (interquartile range [IQR], 47–66). Of these patients, 206 were allocated to the ERAS-C group, and the other 230 patients comprised the ERAS-N group. The overall compliance rate was 70% (IQR, 65%-80%). The ERAS-C group had higher compliance rates [80.00% (IQR, 75.00–85.00%)] than the ERAS-N group [65.00% (IQR, 65.00–70.00%)], P < 0.001). The ERAS-C group had significantly fewer major complications (7.77% vs. 15.65%, OR, 0.449, 95% CI, 0.241–0.836, P = 0.012) and shorter postoperative hospital stays (5 days [IQR, 4–6] vs. 6 days [IQR, 5–7], P < 0.001) than the ERAS-N group. Subgroup analysis indicated that compliance rates greater than 80%, between 65 and 80%, and lower than 65% were associated with decreased major complication rates (6.25%, 8.48% and 22.83%, respectively) and shorter postoperative hospital stays. However, the rates of ICU stay, readmission, reoperation and mortality within 30 days after surgery were not different between groups (P > 0.05).

Conclusion

The results of this study suggest that higher compliance with ERAS components is associated with a lower incidence of major postoperative complications and a shorter postoperative hospital stay.

Effects of preoperative oral carbohydrate administration combined with postoperative early oral intake in elderly patients undergoing hepatectomy with acute-phase inflammation and subjective symptom burden: A prospective randomized controlled study

BACKGROUND

Enhanced recovery after surgery (ERAS) has received increasing attention. Preoperative oral carbohydrate and postoperative early oral feeding (POC-PEOF) as the basic nutrition administration in the ERAS program suffers from low adherence. The role and benefits of administering POC-PEOF in elderly patients with hepatocellular carcinoma (HCC) are unclear. Therefore, the randomized controlled trial evaluated the effects of POC-PEOF in elderly patients with HCC undergoing hepatectomy with inflammation and patient self-reported symptom burden compared with the corresponding outcomes of traditional fasting protocols.

METHODS

Elderly patients with HCC (n = 126) were randomly assigned to two groups using the sealed envelope technique. Sixty-three patients were included in the intervention (POC-PEOF) group and received POC-PEOF administration, whereas the 63 patients in the control (FAST) group underwent conventional fasting. Acute-phase inflammation markers, patient self-reported symptom burdens, and postoperative outcomes were compared between the two groups.

RESULTS

The average age was 69.60 ± 5.00 years in the POC-PEOF group and 70.44 ± 6.15 years in the FAST group. Compared to prolonged fasting, POC-PEOF achieved significant positive results, including lower overall levels of inflammatory response mediators (CRP, IL-6) on postoperative day (POD) 1, POD 3, and POD 5 (P < 0.05), lower patient self-reported symptom burdens of thirst, hunger, anxiety and nausea (P < 0.05), faster gastrointestinal function return with shortened times to first flatus and first defecation (48.31 ± 13.24 h vs. 96.26 ± 23.12 h and 72.87 ± 21.12 h vs. 144.34 ± 23.31 h, and P = 0.034 and P = 0.013, respectively). Furthermore, the average postoperative hospitalization duration in the POC-PEOF group was shorter than that in the FAST group (6.93 ± 0.98 d vs. 8.12 ± 1.15 d, P = 0.042). There was no significant difference of total complications between the groups (25.39 % vs 36.51 %, RR 0.696, 95 % CI 0.408-0.187, P = 0.177).

CONCLUSION

POC-PEOF helps lessen acute-phase inflammation and relieves the subjective symptom burden, which can ensure better positive postoperative outcomes in elderly HCC patients undergoing hepatectomy.

Opportunities and Challenges for the Next Phase of Enhanced Recovery After Surgery: A Review

Importance

Enhanced Recovery After Surgery (ERAS) is a global surgical quality improvement initiative now firmly entrenched within the field of perioperative care. Although ERAS is associated with significant clinical outcome improvements and cost savings in numerous surgical specialties, several opportunities and challenges deserve further discussion.

Observations

Uptake and implementation of ERAS Society guidelines, together with ERAS-related research, have increased exponentially since the inception of the ERAS movement. Opportunities to further improve patient outcomes include addressing frailty, optimizing nutrition, prehabilitation, correcting preoperative anemia, and improving uptake of ERAS worldwide, including in low- and middle-income countries. Challenges facing enhanced recovery today include implementation, carbohydrate loading, reversal of neuromuscular blockade, and bowel preparation. The COVID-19 pandemic poses both a challenge and an opportunity for ERAS.

Conclusions and Relevance

To date, ERAS has achieved significant benefit for patients and health systems; however, improvements are still needed, particularly in the areas of patient optimization and systematic implementation. During this time of global crisis, the ERAS method of delivering care is required to take surgery and anesthesia to the next level and bring improvements in outcomes to both patients and health systems.

Clinical and Economic Outcomes of Enhanced Recovery Dissemination in Michigan Hospitals

OBJECTIVE

To evaluate real-world effects of enhanced recovery protocol (ERP) dissemination on clinical and economic outcomes after colectomy.

SUMMARY BACKGROUND DATA

Hospitals aiming to accelerate discharge and reduce spending after surgery are increasingly adopting perioperative ERPs. Despite their efficacy in specialty institutions, most studies have lacked adequate control groups and diverse hospital settings and have considered only in-hospital costs. There remain concerns that accelerated discharge might incur unintended consequences.

METHODS

Retrospective, population-based cohort including patients in 72 hospitals in the Michigan Surgical Quality Collaborative clinical registry (N = 13,611) and/or Michigan Value Collaborative claims registry (N = 14,800) who underwent elective colectomy, 2012 to 2018. Marginal effects of ERP on clinical outcomes and risk-adjusted, price-standardized 90-day episode payments were evaluated using mixed-effects models to account for secular trends and hospital performance unrelated to ERP.

RESULTS

In 24 ERP hospitals, patients Post-ERP had significantly shorter length of stay than those Pre-ERP (5.1 vs 6.5 days, P < 0.001), lower incidence of complications (14.6% vs 16.9%, P < 0.001) and readmissions (10.4% vs 11.3%, P = 0.02), and lower episode payments ($28,550 vs $31,192, P < 0.001) and postacute care ($3,384 vs $3,909, P < 0.001). In mixed-effects adjusted analyses, these effects were significantly attenuated-ERP was associated with a marginal length of stay reduction of 0.4 days (95% confidence interval 0.2-0.6 days, P = 0.001), and no significant difference in complications, readmissions, or overall spending.

CONCLUSIONS

ERPs are associated with small reduction in postoperative length of hospitalization after colectomy, without unwanted increases in readmission or postacute care spending. The real-world effects across a variety of hospitals may be smaller than observed in early-adopting specialty centers.

Enhanced Recovery after Surgery: History, Key Advancements and Developments in Transplant Surgery

Enhanced recovery after surgery (ERAS) aims to improve patient outcomes by controlling specific aspects of perioperative care. The concept was introduced in 1997 by Henrik Kehlet, who suggested that while minor changes in perioperative practise have no significant impact alone, incorporating multiple changes could drastically improve outcomes. Since 1997, significant advancements have been made through the foundation of the ERAS Society, responsible for creating consensus guidelines on the implementation of enhanced recovery pathways. ERAS reduces length of stay by an average of 2.35 days and healthcare costs by $639.06 per patient, as identified in a 2020 meta-analysis of ERAS across multiple surgical subspecialties. Carbohydrate loading, bowel preparation and patient education in the pre-operative phase, goal-directed fluid therapy in the intra-operative phase, and early mobilisation and enteral nutrition in the post-operative phase are some of the interventions that are commonly implemented in ERAS protocols. While many specialties have been quick to incorporate ERAS, uptake has been slow in the transplantation field, leading to a scarcity of literature. Recent studies reported a 47% reduction in length of hospital stay (LOS) in liver transplantation patients treated with ERAS, while progress in kidney transplantation focuses on pain management and its incorporation into enhanced recovery protocols.

[Structured Implementation of a Fast-Track Program - How Does it Work?]

Fast-track or ERAS programs can give clinically relevant benefits for patients undergoing surgery. They also have financial advantages for the hospital. Despite these facts, fast-track has been implemented in only very few hospitals in Germany. Neither scientific evidence nor reimbursement regulations explain this lack of fast-track acceptance. It seems however that a structured process of change from traditional perioperative medicine to evidence based fast-track therapy is missing in Germany. In other countries, structured programs for fast-track or ERAS implementation have been successful in many hospitals. This article describes structured fast-track implementation divided into three consecutive steps: organisational preparation, clinical implementation and continuous examination of fast-track adherence, functional recovery, morbidity and postoperative length of hospital stay. Due to its complex nature, fast-track implementation should be guided by external fast-track experts.

Role for colorectal teams to support non-colorectal teams to improve clinical outcomes and adherence to ERAS guidelines for segmental colectomy: a cohort study

BACKGROUND

To identify whether compliance with Enhanced Recovery After Surgery (ERAS) Society recommendations is associated with length of stay (LOS) in a New Zealand hospital for patients undergoing segmental colectomy in mixed acute and elective general surgery wards.

METHODS

Consecutive elective colorectal surgeries (n = 770) between October 2012 and February 2019 were audited. Patients with non-segmental colectomies, multi-organ surgeries, LOS > 14 days, and those who died were excluded. Logistic regression was used to determine the relationship between patient demographics, compliance with ERAS guidelines, and suboptimal LOS (> 4 days).

RESULTS

Analysis included 376 patients. Age, surgery prior to 2014, surgical approach, non-colorectal surgical team, operation type, and complications were significantly associated with suboptimal LOS. Non-compliance with ERAS recommendations for laparoscopy [OR 8.9, 95% CI (4.52, 19.67)], removal of indwelling catheters (IDC) [OR 3.14, 95% CI (1.85, 5.51)], use of abdominal drains [OR 4.27, 95% CI (0.99, 18.35)], and removal of PCA [OR 8.71, 95% CI (1.78, 157.27)], were associated with suboptimal LOS (univariable analysis). Multivariable analysis showed that age, surgical team, late removal of IDC, and open approach were independent predictors of suboptimal LOS.

CONCLUSIONS

Non-compliance with ERAS guidelines for laparoscopic approach and early removal of IDC was higher among procedures performed by non-colorectal surgery teams, and was also associated with adverse postoperative events and suboptimal LOS. This study demonstrates the importance of the surgical team's expertise in affecting surgical outcomes, and did not find significant independent associations between most individual ERAS guidelines and suboptimal LOS once adjusting for other factors.

Reducing hospital stay for colorectal surgery in ERAS setting by means of perioperative patient education of expected day of discharge

PURPOSE

Despite the enhanced recovery after surgery (ERAS) protocol, length of stay (LOS) after colorectal surgery varies considerably. The majority of longer admissions is often not medically necessary. We aimed to investigate possible reduction of LOS by perioperative education with an expected discharge date (EDD).

METHODS

This single-centre retrospective study included 578 patients who underwent surgery for colorectal cancer in 2016 with standard care (ERAS) and in 2018 with the addition of EDD education program (ERAS+). A comparison was made of a 1-year period prior to and following the implementation of EDD. The EDD was discussed at the outpatient clinic, preoperatively and during admission (with both the patient and family members daily). Standard EDD varied between 3 and 5 days depending on the resection type. Primary outcome was LOS; secondary outcomes were readmission, serious complications and 90-day mortality.

RESULTS

Patients in ERAS+ (n = 242) had a shorter median LOS (4.0 vs. 5.0, p < 0.001) compared to patients in the regular ERAS group (n = 336). Fewer patients of ERAS+ experienced postoperative complications (71 (29.3%) vs. 198 (58.9%), p < 0.001). No difference was found in the number of readmissions (23 (9.5%) vs. 34 (10.1%), p = 0.807), reinterventions (25 (10.3%) vs. 30 (8.9%), p = 0.571) or mortality (5 (2.1%) vs. 9 (2.7%), p = 0.261) between the two groups.

CONCLUSION

It is possible to reduce LOS within the ERAS program, by better perioperative education and expectation management of patients with use of an EDD. This program ensures better understanding, faster discharge and lower costs for the hospital without added risk of readmissions or complications.

Early postoperative mobilization in patients undergoing abdominal surgery: a best practice implementation project

OBJECTIVES

The aim of this project was to improve early postoperative mobilization in patients undergoing abdominal surgery according to best practice.

INTRODUCTION

Early mobilization is a crucial element of postoperative care; however, there are challenges implementing early mobilization protocols in daily practice. This project used the evidence to improve awareness and practice of early mobilization in patients undergoing abdominal surgery.

METHODS

This study utilized clinical audit strategies under the JBI Practical Application of Clinical Evidence System (JBI PACES) module. An audit-feedback cycle was used from April 2018 to August 2018. The baseline audit was conducted using 18 nurses and 30 patients in a general surgery ward. The Getting Research into Practice audit and feedback tool was used to identify barriers, strategies, resources and outcomes. After implementing evidence-based strategies, a follow-up was conducted using the same number of samples and audit criteria. We analyzed the compliance with best practice and its impact on length of hospitalization, postoperative physical activities, gastrointestinal function and complications.

RESULTS

After implementing best-practice strategies, the compliance rate of the six criteria improved as follows: criterion 1 from 0% to 100% (P = 0.000), criterion 2 from 87% to 100% (χ = 4.29, P = 0.038), criterion 3 from 60% to 70% (χ = 6.67, P = 0.010), criterion 4 from 7% to 79% (χ = 52.55, P = 0.000), criterion 5 from 40% to 70% (χ = 35.00, P = 0.000), and criterion 6 from 0% to 100% (P = 0.000). The differences in the length of hospitalization and physical activities between the pre-implementation and post-implementation were statistically significant (all P < 0.05). The rate of postoperative complications did not show a significant difference because of low occurrence.

CONCLUSIONS

The results indicate that evidence-based practice is an effective method for enhancing early recovery in patients undergoing abdominal surgery through promoting early mobilization. Sustaining best practice should continue through further follow-up audits.

Using provider-focused education toolkits can aid enhanced recovery programs to further reduce patient exposure to opioids

Background

Evidence-based perioperative analgesia is an important tactic for reducing patient exposure to opioids in the perioperative period and potentially preventing new persistent opioid use.

Study design

We assessed the impact of a multifaceted optimal analgesia program implemented in the setting of a mature surgical pathway program at an academic medical center. Using existing multidisciplinary workgroups established for continuous process improvement in three surgical pathway areas ((colorectal, gynecology, and urologic oncology (cystectomy)), we developed an educational toolkit focused on implementation strategies for multimodal analgesia and non-pharmacologic approaches for managing pain with the goal of reducing opioid exposure in hospitalized patients. We analyzed prospectively collected data from pathway patients before dissemination of the toolkit (July 2016–June 2017; n = 869) and after (July 2017–June 2018; n = 838). We evaluated the association between program implementation and use of oral morphine equivalents (OME), average pain scores, time to first ambulation after surgery, urinary catheter duration, time to solid food after surgery, length of stay, discharge opioid prescriptions, and readmission.

Results

Multivariate regression demonstrated that the program was associated with significant decreases in intraoperative OME (14.5 ± 2.4 mEQ (milliequivalents) reduction; p < 0.0001), day before discharge OME (18 ± 6.5 mEQ reduction; p < 0.005), day of discharge OME (9.6 ± 3.28 mEQ reduction; p < 0.003), and discharge prescription OME (156 ± 22 mEq reduction; p < 0.001). Reduction in OME was associated with earlier resumption of solid food (0.58 ± 0.15 days reduction; p < 0.0002).

Conclusion

Our multifaceted optimal analgesia program to manage perioperative pain in the hospital was effective and further improved analgesia in the setting of a mature enhanced recovery program.

The History of ERAS (Enhanced Recovery After Surgery) Society and its development in Latin America

The shortage of hospital beds and changes in the payment model have promoted an increased attention and financing of programs that focus on perioperative care efficiency in. Latin America. In this paper, Enhanced Recovery After Surgery (ERAS) programs developed by the ERAS® Society will be discussed. The implementation and use of ERAS®Society Guidelines consistently demonstrated a reduction in postoperative complications, hospital stay and costs. In the current paper, the definition of ERAS programs, their core elements, and the results of their implementation and regional developments are presented with special focus on Latin America.

Evaluation of Enhanced Recovery After Following a Surgical Protocol for Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Carcinomatosis

Introduction:

Cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy (CRS ± HIPEC) has positive effects on the survival of patients with peritoneal carcinomatosis (PC) due to intra-abdominal tumors. Currently, the available literature on the safety of the Enhanced Recovery After Surgery (ERAS) protocol for PC, which is associated with severe morbidity and mortality, is insufficient.

Aim:

This study aimed to present our results from treating patients using the ERAS protocol for PC that developed due to intra-abdominal tumors.

Material and Methods:

The data of 120 consecutive patients with PC due to different etiologies of abdominal origin and who underwent CRS ± HIPEC were analyzed. The patients were divided into two groups according to whether the ERAS protocol was applied. Information on demographics, length of hospital stay, cost, morbidity, and mortality was statistically compared between groups.

Results:

A total of 102 patients were included in the study. The first 40 patients did not undergo the ERAS protocol, whereas 62 patients did undergo the protocol. The mean length of hospital stay was 10 days in the non-ERAS group and 7 days in the ERAS group. The ERAS group was observed to have earlier mobilization, earlier gas and stool release, lower oral intake, and fewer respiratory problems than the non-ERAS group.

Conclusion:

CRS ± HIPEC has a positive effect on survival. The simultaneous application of the ERAS protocol with the aforementioned procedure has positive effects on intestinal motility and postoperative outcomes. In addition, this protocol may reduce costs by shortening the length of hospital stay.

Enhanced recovery after surgery programmes in older patients undergoing hepatopancreatobiliary surgery: what benefits might prehabilitation have?

Due to an aging population and the related growing number of less physically fit patients with multiple comorbidities, adequate perioperative care is a new and rapidly developing clinical science that is becoming increasingly important. This narrative review focuses on enhanced recovery after surgery (ERAS®) programmes and the growing interest in prehabilitation programmes to improve patient- and treatment-related outcomes in older patients undergoing hepatopancreatobiliary (HPB) surgery. Future steps required in the further development of optimal perioperative care in HPB surgery are also discussed. Multidisciplinary preoperative risk assessment in multiple domains should be performed to identify, discuss, and reduce risks for optimal outcomes, or to consider alternative treatment options. Prehabilitation should focus on high-risk patients based on evidence-based cut-off values and should aim for (partly) supervised multimodal prehabilitation tailored to the individual patient's risk factors. The program should be executed in the living context of these high-risk patients to improve the participation rate and adherence, as well as to involve the patient's informal support system. Developing tailored (multimodal) prehabilitation programmes for the right patients, in the right context, and using the right outcome measures is important to demonstrate its potential to further improve patient- and treatment-related outcomes following HPB surgery.

Enhanced recovery after surgery review and urology applications in 2020

Purpose: To explore enhanced recovery after surgery (ERAS) components and their current application to major urologic surgeries, barriers to implementation and maintenance of the associated quality improvement. Data Identification: An English language literature search was done using PubMed. Study Selection: After independent review, 55 of the original 214 articles were selected to specifically address the stated purpose. Data Extraction: Clinical trials were included, randomized trials were prioritized, but robust observational studies were also included. Results of Data Synthesis: Many ERAS components have good data to support usage in radical cystectomy (RC) patients. Most ERAS programs include multidisciplinary teams carrying out multimodal pathways to hasten recovery after a major operation. ERAS components generally include preoperative counseling and medical optimization, venous thromboembolism prophylaxis, ileus prevention, avoidance of fluid overload, normothermia maintenance, early mobilization, pain control and early feeding, all leading to early discharge without increased complications or readmissions. Although there may not be specific data pertaining to other major urologic operations, the principles remain similar and ERAS is easily applicable. Conclusion: The benefits of ERAS programs are well established for RC and principles are easily applicable to other major urology operations. Barriers to implantation and maintenance of ERAS must be recognized to continue to maintain the benefits of these programs.

Systematic scoping review of enhanced recovery protocol recommendations targeting return of gastrointestinal function after colorectal surgery

BACKGROUND

Post-operative ileus (POI) and delayed return of gastrointestinal (GI) function are common complications after colorectal surgery. There is a lack of uniformity in enhanced recovery protocols (ERPs) with regards to interventions used to target these complications. This systematic review aims to categorize and summarize management recommendations available from published ERPs.

METHODS

A systematic search of Ovid MEDLINE, Embase, Cochrane Library and PubMed databases was performed from January 1990 to May 2018. All studies publishing enhanced recovery or fast-track or multimodal pathway protocols for colorectal surgery in their full-text were included. Data on interventions aimed at reducing the duration of POI were extracted, as well as references quoted to support specific interventions.

RESULTS

Of 481 manuscripts screened, 37 published ERPs were identified from 37 studies (18 cohort, seven historical-control, five guidelines, four randomized controlled trials, one randomized controlled trial protocol, one case series and one narrative review). The most commonly recommended interventions were magnesium-based laxatives (18 of 37, 48.6%), chewing gum (13 of 37, 35.1%), Alvimopan (6 of 37, 16.2%), lactulose (4 of 37, 10.8%), neostigmine (2 of 37, 5.4%) and bisacodyl (2 of 37, 5.4%). Geographical trends were noted for the various interventions, but high-quality evidence was only referenced to support the use of Alvimopan.

CONCLUSION

ERP recommendations specific to interventions targeting POI and return of GI function are varied. While laxatives are the most commonly recommended intervention, there is only weak evidence reported to support this practice.

Modern perioperative medicine - past, present, and future

Modern perioperative medicine has dramatically altered the care for patients undergoing major surgery. Anaesthetic and surgical practice has been directed at mitigating the surgical stress response and reducing physiological insult. The development of standardised enhanced recovery programmes combined with minimally invasive surgical techniques has lead to reduction in length of stay, morbidity, costs, and improved outcomes. The enhanced recovery after surgery (ERAS) society and its national chapters provide a means for sharing best practice in this field and developing evidence based guidelines. Research has highlighted persisting challenges with compliance as well as ensuring the effectiveness and sustainability of ERAS. There is also a growing need for increasingly personalised care programmes as well as complex geriatric assessment of frailer patients. Continuous collection of outcome and process data combined with machine learning, offers a potentially powerful solution to delivering bespoke care pathways and optimising individual management. Long-term data from ERAS programmes remain scarce and further evaluation of functional recovery and quality of life is required.

Managing elderly with colorectal cancer

The aging population is an increasing healthcare concern in developing countries. In Singapore, 25% of the local population are expected to be older than 65 years old by 2030. Colorectal cancer (CRC) is ranked third most diagnosed cancers worldwide with up to 1.8 million new cases diagnosed in 2018. 60% of newly diagnosed CRC are among patients who are 70 years or older and hence majority of these patients will invariably face challenges with frailty and multiple comorbidities that require appropriate assessment and stratification. The standard of care in patients with stage I or II CRC is surgery with curative intent. For patients with stage III CRC, upfront surgical resection of tumor along with adjuvant chemotherapy is the internationally recommended treatment approach. As for those patients with metastatic disease, they are usually managed within a multidisciplinary team and considered for surgical resection if deemed feasible. Elderly patients are mostly burdened with frailty, functional dependency and existing co-morbidities, all of which are predictors of early postoperative mortality and morbidity in patients with CRC. This article thus aims to review existing evidence to discuss the intricate decision-making process for the surgical management of elderly patient with CRC.

ERAS, length of stay and private insurance: a retrospective study

PURPOSE

Hospital discharge after colorectal resection within an Enhanced Recovery After Surgery (ERAS) program occurs earlier compared to standard-care postoperative pathways but often later than what objective criteria of "readiness for discharge" could allow. The aim of this study was to analyse reasons and risk factors of such discharge delay.

METHODS

All elective patients admitted for colorectal resection at the regional Hospital of Lugano in 2014 and 2015 were included. The postoperative day on which patients fulfilled consensus agreed criteria (according to Fiore) for readiness for discharge (POD-F) and the effective day of discharge (POD-D) were determined. We analysed the reasons for discharge delay (POD-D>POD-F) and performed univariate and multivariate analysis to determine risk factors.

RESULTS

One hundred thirty-eight patients were included in the study. Median POD-F was 5 (2-48) days, POD-D was 6 (3-50) days. In 94 patients, POD-D occurred later than POD-F with a median delay of 1 (1-11) days. Reasons for discharge delay were insufficient social support in 13 (14%), patient's preference in 39 (41%) and medical team preference in 41 (44%). Private insurance (OR 2.61, 95%CI 1.08-6.34, p = 0.034) and patient discharged on a day other than Monday (OR 2.94, 95%CI 1.16-7.14, p = 0.023) were independent predictors for discharge delay.

CONCLUSION

Even when objective criteria for readiness for discharge have been fulfilled, patients and/or doctors often do not feel comfortable with hospital discharge at this time point. Length of stay, even within an ERAS program, is still influenced by several non-medical factors and is therefore not a precise surrogate marker of outcomes.

Association Between Compliance to an Enhanced Recovery Protocol and Outcome After Elective Surgery for Gastric Cancer. Results from a Western Population-Based Prospective Multicenter Study

BACKGROUND

The association between compliance to an enhanced recovery protocol (ERAS) and outcome after surgery for gastric cancer has been poorly investigated, particularly in Western patients. The aim of the study was to evaluate whether the rate of adherence to the ERAS program was correlated with outcome and time of discharge.

METHODS

A prospective, observational, multicenter study was designed to be performed at Italian referral centers for gastric surgery. The protocol was discussed and approved by the Italian Research Group on Gastric Cancer. Twenty-three ERAS domains were applied. A multivariate logistic regression was used to assess the association between ERAS compliance and overall and major complication rates. The Poisson regression model (measured as mean ratios) was used to assess the association of ERAS compliance rate and length of stay (LOS).

RESULTS

Eight centers participated and 290 subjects with a median age of 73 years were enrolled. The overall rates of adherence to pre-, intra-, and postoperative ERAS items were 69.8%, 60.3%, and 82.5%, respectively. At the multivariate model, there was an association between overall rate of morbidity and an overall ERAS compliance rate greater than 70% (OR 0.413; 95% CI 0.235-0.7240; P 0.002). A similar association was found for major complications (OR 0.328; 95% CI 0.151-0.709; P 0.005). The Poisson regression showed that in patients with ERAS compliance rate >70%, LOS was reduced of approximately 20% (mean ratio 0.812; 95% CI 0.694-0.950; P 0.009).

CONCLUSIONS

These results suggest a moderate compliance to an ERAS program and a significant association between adherence and outcomes.

Postoperative complications are main reason for noncompliance with enhanced recovery after surgery program in patients undergoing hepatectomy and pancreatectomy

Background and Aim

Enhanced recovery after surgery (ERAS) protocols are reported to improve postoperative outcomes in patients undergoing a routine protocol and postoperative outcomes in patients undergoing hepatic and pancreatic resections at our institution.

Methods

A total of 99 consecutive patients at a single institution managed with a similar ERAS protocol were divided into the “early” (50 patients) and “late” (49 patients) cohorts. Both cohorts were statistically identical in demographics and range of surgical procedures performed. Postoperative complications, readmission, reoperation rates, and length of stay were analyzed. Categorical variables were statistically compared using Fisher's exact test and continuous variables using t‐test and Mann–Whitney U‐test when appropriate.

Results

There were 32 hepatectomies/18 pancreatectomies in the “early” cohort and 22 hepatectomies/29 pancreatectomies in the “late” cohort. The overall complication rate was 38.8%, with a 30‐day readmission rate and reoperation rate of 16.1 and 5%, respectively. There was one mortality (1%). Group‐specific overall complication rate (40 vs 38.7%, P = 0.8), readmission rate (20 vs 12.2%, P = 0.4), reoperation rate (6 vs 4%, P = 1.0), and mortality (2 vs 0%, P = 1.0) were not statistically significant between both groups.

Conclusions

Despite similar rates of adherence to the established ERAS 24 protocol, there was no improvement in median length of stay (7 days) between the “early” and “late” groups. The only reason for noncompliance with the ERAS protocol was development of surgery‐related complications.

IMPLEMENTATION OF ENHANCED RECOVERY AFTER COLORECTAL SURGERY (ERAS) PROTOCOL: INITIAL RESULTS OF THE FIRST BRAZILIAN EXPERIENCE

BACKGROUND

Guidelines for enhanced recovery after surgery have their bases in colonic surgery, through the first protocols published in 2012. Since then, this practice has spread throughout the world, mainly due to improvements in surgical outcomes associated with resource savings.

AIM

To analyze the first prospective results after the implementation of the guidelines.

METHODS

Were retrospectively analyzed 48 patients operated in the institution prior to the standardization. This group was then compared with a series of 25 patients operated consecutively after the guidelines were implemented.

RESULTS

With a 68.6% compliance rate, hospital length of stay (p=0.002), use of abdominal drains (p<0.001) and mechanical bowel preparation (p<0.001) were reduced. Mortality rates, anastomotic fistula, abdominal abscesses and reoperations were also reduced, but without statistical significance.

CONCLUSION

Enhanced recovery after surgery protocols benefit patients care, resulting in better outcomes and possibly resource savings. Even with some limitations, its implementation is feasible in the Brazilian Public Health System.

A Provincial Assessment of the Barriers and Utilization of Enhanced Recovery After Colorectal Surgery

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols after colorectal surgery use several perioperative, intraoperative and postoperative interventions that decrease morbidity, length of stay, and improve patient satisfaction. ERAS is increasingly being considered standard of care; however, uptake of formalized protocols remains low. The objective is to characterize the provincial rates of ERAS utilization after colorectal surgery and identify barriers and limitations to ERAS implementation.

METHODS

A total of 797 general surgeons were identified through the College of Physicians and Surgeons of Ontario. A survey identifying demographics, rates of ERAS utilization, and barriers to implementation was distributed. Logistic regression determined the effects of demographic and hospital covariates on ERAS utilization.

RESULTS

A total of 235 general surgeons representing 84 Ontario hospitals participated (response rate 29.5%). Surgeons working in academic or large community hospitals represented the majority of the cohort (30.5% and 47.2%, respectively). Multivariable analysis showed no significant effect of surgeon demographics, years in practice, or training details on ERAS protocol utilization; however, practicing in small community hospitals (compared with large and academic hospitals) was significantly associated with not using ERAS protocols (odds ratio, 0.02; 95% confidence interval, 0-0.3; P = 0.005). Over 50% of respondents used ERAS principles but did not have a formal protocol. Barriers to implementing ERAS protocols included patient variability, lack of institutional and nursing support, and poor communication with the care team.

CONCLUSIONS

Small community hospitals are less likely to use formal ERAS protocols; however, most Ontario surgeons are using ERAS principles after colorectal surgery. Barriers to ERAS implementation are broad and the present study has provided a pragmatic solution to change.

Is It Possible to Maintain High Compliance with the Enhanced Recovery after Surgery (ERAS) Protocol?-A Cohort Study of 400 Consecutive Colorectal Cancer Patients

The aim of our study was to evaluate the implementation and degree of adherence to the Enhanced Recovery after Surgery (ERAS) protocol in a group of 400 patients operated laparoscopically for colorectal cancer, and to assess its impact on the short-term results. The prospective study included patients with histologically confirmed colorectal cancer undergoing elective laparoscopic resection from years 2012 to 2017. For the purpose of further analysis, patients were divided into four groups: 100 consecutive patients were in each group. There were no statistically significant differences between groups in demographic parameters. The mean compliance with the ERAS protocol in the entire study group was 84.8%. Median adherence differed between the groups 76.9% vs. 92.3% vs. 84.6% vs. 84.6%, respectively (p < 0.0001). There were statistically significant differences between groups in the tolerance of oral diet (54% vs. 83% vs. 83% vs. 64%) and mobilization (74% vs. 92% vs. 91% vs. 94%) on the first postoperative day. In subsequent groups, time to first flatus decreased (2.5 vs. 2.1 vs. 2.0 vs. 1.7 days, p = 0.0001). There were no statistical differences in the postoperative morbidity rate between groups (p = 0.4649). The median length of hospital stay in groups was 5 vs. 4 vs. 4 vs. 4 days, respectively (p = 0.0025). Maintaining high compliance with the ERAS protocol is possible, despite the slight decrease that occurs within a few years after its implementation. This decrease in compliance does not affect short-term results, which are comparable to those shortly after overcoming the learning curve.

Implementation of an Enhanced Recovery After Spine Surgery program at a large cancer center: a preliminary analysis

This study describes the implementation of a multimodal, multidisciplinary, evidence-based ERAS program in oncologic spine surgery, identifies and measures several relevant postoperative recovery outcomes, and demonstrates the feasibility and potential benefit of the program in improving analgesia and decreasing opioid consumption. The study underscores the importance of defining and capturing meaningful, patient-specific, and patient-reported outcomes, and constant evaluation and monitoring of a group's compliance with the program. The study represents the steppingstone for evaluation and improvement of a young ERAS program for spine surgery and serves as a roadmap for further initiatives and larger-scale studies.
