Systematic review and meta-analysis of enhanced recovery programmes in surgical patients

A surgical perspective of ERAS guidelines in thoracic surgery

PURPOSE OF REVIEW

Guidelines for enhanced recovery after surgery (ERAS) have recently been published for lung surgery. Although some of the recommendations are generic or focused on anesthetic and nursing care, other recommendations are more specific to a thoracic surgeon's practice. The present review concentrates on the surgical approach, optimal chest drain management, and the importance of early mobilization.

RECENT FINDINGS

Most lung cancer resections are still performed via an open thoracotomy approach. If a thoracotomy is to be used, a muscle-sparing approach may result in reduced pain and better postoperative function. Sparing of the intercostal bundle also reduces pain. There is now evidence that minimally invasive surgery for early lung cancer results in superior patient outcomes. Postoperatively, single chest tubes should be used without the routine application of external suction. Digital drainage systems are more reliable and may produce superior outcomes. Conservative chest drain removal policies are unnecessary and impair patient recovery. Early mobilization protocols should be instigated to reduce postoperative complications.

SUMMARY

The use of ERAS after lung surgery has the potential to improve patient outcomes. Although specific surgical elements are in the minority, thoracic surgeons should be involved in all aspects of perioperative care as part of the wider multidisciplinary team.

ERAS and patient reported outcomes in thoracic surgery: a review of current data

Quality-focused, cost-effective, patient-centered care is at the forefront of current healthcare reform. Recent data show that enhanced recovery after surgery (ERAS) results in improved surgical outcomes and decreased hospital costs. As a result, ERAS has been widely accepted among multiple surgical subspecialties as a modality for increasing the value of healthcare delivered to our patients. While this objective data is convincing for practitioners and administrators alike, how ERAS directly impacts the patient experience is unclear. Patient reported outcomes (PRO) are starting to drive patterns of healthcare delivery and influence surgical decision-making. In order to improve surgical outcomes and deliver patient-centered care, it is imperative that clinicians start reviewing objective metrics contained within morbidity and mortality data alongside subjective data regarding patients' experience. This article reviews the current data surrounding both ERAS and PROs within thoracic surgery and investigates how the two concepts are ultimately related.

Impact of enhanced recovery after surgery on outcomes of elderly patients undergoing open thoracic surgery

OBJECTIVE

An enhanced recovery after surgery (ERAS) program might be effective for postoperative recovery in elderly patients undergoing thoracic surgery. This study aimed to clarify the impact of ERAS on the post-operative recovery of elderly patients, with regard to shortening hospital stay and reducing complications after open thoracic surgery.

METHODS

We used a prospectively collected database and retrospectively accessed the data of patients who underwent lobectomies or segmentectomies for pulmonary malignancies from April 2013 to March 2018 and evaluated outcomes after implementation of ERAS. ERAS patients were those who completed an ERAS program. The control patients were those who underwent surgery before June 2015 and later operated patients who did not receive ERAS. Propensity score matching was performed to balance the characteristics of patients in both groups. Patients were also divided into the following three groups for evaluating the efficacy of ERAS: patients aged < 65 years, 65-74 years of age, and ≥ 75 years of age.

RESULTS

Before propensity score matching, the ERAS patients had shorter postoperative stay, shorter duration of chest tube drainage, and lower rate of postoperative complications than the patients without ERAS. The difference between readmission rates was not significant. After matching, the ERAS patients had shorter postoperative stay. The difference between readmission rates was not significant. After matching, the postoperative hospital stay was shorter in the patients aged ≥ 65 years.

CONCLUSIONS

ERAS shortened the length of postoperative hospital stay in patients aged ≥ 65 years and did not increase readmission rates.

Early Discharge Does Not Increase Readmission Rates After Minimally Invasive Anatomic Lung Resection

Objective

Enhanced recovery pathways reduce length of stay and costs following lung resection. However, many fear that early discharge may lead to increased hospital readmissions. In this study, we aimed to determine whether early discharge was associated with increased readmission following anatomic lung resection.

Methods

Using the lung resection database approved by our institutional review board, we identified all patients undergoing minimally invasive lobectomy and segmentectomy between January 2010 and March 2017 at our institution, where an enhanced recovery pathway is well established. Thirty-day readmissions were compared between patients with short- and average length of stay, defined as 1 to 2 days and 3 to 5 days, respectively. Multivariable logistic regression analysis of patients matched by propensity scores was performed to determine odds of 30-day readmission for each group. Significance was set at P < 0.05.

Results

A total of 296 patients met inclusion criteria. Unadjusted analysis revealed a 3-fold increased rate of readmission in the group with average length of stay (9%, n = 12) versus the group with short length of stay (3%, n = 5; P < 0.01). At baseline, patients with average length of stay had increased rates of preoperative chemotherapy (13%, n = 18 vs. 4%, n = 6; P < 0.01) and radiation (12%, n = 16 vs. 3%, n = 5). Patients with average length of stay also had higher rates of lobectomy (95%, n = 127 vs. 86%, n = 140; P = 0.02) and postoperative complications (31%, n = 41 vs. 4%, n = 7; P < 0.01). On multivariable analysis, patients with average length of stay had a 2.3-fold greater odds of readmission, which was not statistically significant (OR = 2.33; 95% CI, 0.60 to 9.02; P = 0.22).

Conclusions

Early discharge following minimally invasive anatomic lung resection does not increase the risk of hospital readmission in patients treated within an enhanced recovery pathway.

Does enhanced recovery improve the survival rates of patients 3 years after undergoing surgery to remove a tumor in the colon?

PURPOSE

The advantages of enhanced recovery programs (ERP) after colorectal surgery for morbidity and length of stay are well known. On a longer term, evidence is much more limited. The aim of this study is to determine the impact of ERP on survival after 3 years of follow-up, following colorectal cancer surgery.

METHODS

All the patients undergoing resection for colorectal cancer between the years 2010 and 2014 were included. Patients were classified according to their compliance with the ERP (< 70 or ≥ 70%).

RESULTS

Among the 206 patients included during the period, 129 were male (62.6%). The 3-year overall survival rate was 70.4% (145 patients) and relapse-free survival was 59.2% (122 patients). The survival after 3 years was influenced by the initial metastatic status (p < 0.0001), operative morbidity (p < 0.001), and the presence of peritumoral emboli (p = 0.006). However, the compliance with the ERP ≥ 70% did not influence overall survival (p = 0.63), nor relapse-free survival (p = 0.93). The same observations were found among the "at-risk" population (synchronous metastasis and postoperative complication).

CONCLUSION

The ERP does not seem to influence the 3-year relapse-free survival after colorectal resection for cancer.

Enhanced recovery after elective surgery for lung cancer patients: analysis of current pathways and perspectives

The concept of enhanced recovery after surgery (ERAS), initially introduced in the field of colorectal surgery, has been developed in order to optimize the postoperative course. In recent years the number of authors analyzing the role of ERAS in lung cancer surgery is increasing, highlighting several interventions with positive effects on the postoperative course. Yet it is still difficult to draw definite conclusions and specific guidelines, as most of these studies largely differ for their methodological aspects and study populations. Herein we focus on the key elements of each single intervention, trying to identify what we can apply in a common pathway, and which aspects are still to be evaluated for the validation of an ERAS program.

Clinical Outcomes of a 14-Day In-Hospital Stay Program in Patients Undergoing Head and Neck Cancer Surgery With Free Flap Reconstruction Under the National Health Insurance System

Objectives

Length of in-hospital stay (LOS) is often regarded as a surrogate marker of efficiency in medical care. A shorter stay can redistribute medical resources to more patients if patient outcomes would not be worsened. However, the adequate LOS remains largely understudied for a complex head and neck cancer (HNC) surgery and free flap reconstruction.

Methods

Active management of LOS (14-day LOS program) included detailed preoperative surgical planning, intensive wound care, postoperative early ambulation and positive psychological encouragement. It was applied to 43 patients undergoing HNC surgery and free flap reconstruction. Outcomes such as noninferior oncological results, rates of timely adjuvant treatments and complications were compared with those of 125 patients without active management of LOS. In addition, the medical costs of shortened LOS were compared with those of the control group. Cases undergoing HNC surgery as a salvage treatment were excluded from both groups for analyses.

Results

Active management of LOS resulted in less in-hospital period compared to the control group (15.0 vs. 21.0 days, P=0.001), and reduced medical costs significantly. Incidence of postoperative complications was comparable between the two groups. Oncological outcomes did not differ significantly according to LOS. In all patients in both groups, initial high T status (T3–4) and occurrence of postoperative complications were independent risk factors for long LOS (>30 days).

Conclusion

In patients undergoing HNC surgery with free flap reconstruction as an initial treatment, a 14-day LOS could be safe in terms of comparable oncological outcomes and postoperative complications. To achieve this goal safely, careful management for T3–4 tumors and prevention of postoperative complications seem to be necessary.

Patient Satisfaction and Quality of Life with Enhanced Recovery Protocols

While studies have demonstrated the benefits of Enhanced Recovery after Surgery (ERAS) programs in reducing length of stay and costs without increasing complications, fewer studies have evaluated patient satisfaction and quality of life (QOL) with enhanced recovery protocols. The aim of this project was to summarize the literature comparing satisfaction and quality of life after colorectal surgery following treatment within an ERAS protocol to standard postoperative care. The available evidence suggests patients suffer no detriment to satisfaction or quality of life with use of ERAS protocols, and may suffer less fatigue and return to activities sooner. Most publications reported no adverse effects on postoperative pain. However, a limited number of studies suggest patients may experience increased early postoperative pain with ERAS pathways, particularly following open colorectal procedures. Future research should focus on potential improvements in ERAS protocols to better manage postoperative pain. Overall, the evidence supports more widespread implementation of ERAS pathways in colorectal surgery.

Multi-modal prehabilitation: addressing the why, when, what, how, who and where next?

Just as there is growing interest in enhancing recovery after surgery, prehabilitation is becoming a recognised means of preparing the patient physically for their operation and/or subsequent treatment. Exercise training is an important stimulus for improving low cardiovascular fitness and preserving lean muscle mass, which are critical factors in how well the patient recovers from surgery. Despite the usual focus on exercise, it is important to recognise the contribution of nutritional optimisation and psychological wellbeing for both the adherence and the response to the physical training stimulus. This article reviews the importance of a multi-modal approach to prehabilitation in order to maximise its impact in the pre-surgical period, as well as critical future steps in its development and integration in the healthcare system.

Effectiveness of Parecoxib Sodium Combined with Transversus Abdominis Plane Block for Pain Management After Hepatectomy for Hepatocellular Carcinoma: A Prospective Controlled Study

BACKGROUND This study aimed to investigate the effectiveness of perioperative parecoxib sodium combined with transversus abdominis plane (TAP) block on postoperative pain management following hepatectomy in patients with hepatocellular carcinoma (HCC). MATERIAL AND METHODS One hundred patients with HCC who underwent hepatectomy were randomized into a study group (n=51) and a control group (n=49). The study group received 40 mg of parecoxib sodium 30 minutes before anesthetic induction, and 150 mg of 0.375% ropivacaine with 5 mg dexamethasone as TAP inhibitors, before closing the abdominal incision. The control group received 40 mg of placebo 30 minutes before anesthetic induction, without TAP block. Postoperatively, all patients received patient-controlled intravenous analgesia (PCIA) and evaluation with subjective visual analog scale (VAS) pain scores. Data on adverse events, postoperative ambulation (>6 hours/day), time of flatus and defecation, and hospitalization duration were recorded. RESULTS Pain scores of the study group were significantly lower compared with the control group on the first three postoperative days. No significant differences were found between the two groups in terms of adverse events. In the study group, the number of cases of postoperative ambulation was significantly more than the control group. The onset of flatus and defecation and duration of hospital stay in the study group were significantly shorter in the study group compared with the control group. CONCLUSIONS Parecoxib sodium combined with TAP block effectively reduced postoperative pain, improved ambulation, improved gastrointestinal function, and shortened hospitalization time following hepatectomy in patients with HCC without adverse effects.

Impact of Enhanced Recovery after Surgery protocol on immediate surgical outcome in elderly patients undergoing pancreaticoduodenectomy

The numbers of patients undergoing pancreaticoduodenectomy are increasing and considerable percentage is elderly patients. Pancreaticoduodenectomy is a major and complicated surgery. The morbidity and mortality following pancreaticoduodenectomy have significantly reduced in recent times; it still remains unclear in elderly patients. Applications of Enhanced Recovery after Surgery protocol have contributed for this better outcome. In this retrospective study, patients who underwent pancreaticoduodenectomy with Enhanced Recovery after Surgery protocol were included and divided into two groups (< 60 years vs ≥ 60 years). The "elderly patients" (≥ 60 years) were defined based on the WHO definition for Indian subcontinent. Outcomes were analyzed in terms of postoperative morbidity, mortality and length of hospital stay. Total 103 patients underwent pancreaticoduodenectomy during the study period (January 2012-December 2017). The mean age was 56.6 ± 10.32 years. Fifty-six (54.37%) patients were aged < 60 years (young group) and 47 (45.63%) patients were aged ≥ 60 years (elderly group). There was no difference between the groups in terms of age, gender, co-morbidity, preoperative drainage and diagnosis. There was no significant difference in the morbidity and mortality (p > 0.05). Delayed gastric emptying was the most common complication which was 25.24% (21% vs 23.41%). Pancreatic fistula rate was 13.59% (8.9% vs 12.76%) and hemorrhage was 4.85% (5.4% vs 4.3%). Mortality was 4.85%. Postoperative hospital stay was comparable (14.7 days vs 15.3 days) (p = 0.164). Pancreaticoduodenectomy is a safe surgical procedure in elderly patients in comparison to young patients. Application of Enhanced Recovery after Surgery protocol can improve the outcome further.

The future of recovery - Integrated, digitalised and in real time

Traditional perioperative risk prediction recovery identifies patient populations at risk of suboptimal recovery but not individual patients in whom this actually occurs and in whom timely intervention is beneficial. Patient-focused recovery emphasises a return to a semblance of normality and an ability to perform activities previously undertaken. A patient's sense of self-efficacy and engagement in their own care positively influences functional improvement and emotive recovery. The future of recovery assessment is that which is individualised, digitalised, integrated and in real time. Real-time recovery (RTR) assessment is the contemporaneous collection, analysis and reporting of data that enable the identification of suboptimal recovery in individual patients in a timeframe that minimises the delay in the implementation of the targeted treatment. There is a need to validate the clinical utility of existing biometric technology, wireless hybrid devices and digitalised platforms in providing both clinician and patient with RTR data and to determine the effect, if any, that RTR has on patient engagement and outcome.

ERAS protocol validation in a propensity-matched cohort of patients undergoing colorectal surgery

PURPOSE

Enhanced recovery after surgery (ERAS) provides many benefits. However, important knowledge gaps with respect to specific components of enhanced recovery after surgery remain because of limited validation data. The aim of the study was to validate a mature ERAS protocol at a different hospital and in a similar population of patients.

METHODS

This is a retrospective analysis of patients undergoing elective colorectal surgery from 2009 through 2016. Patients enrolled in ERAS are compared with those undergoing the standard of care. Patient demographic characteristics, length of stay, pain scores, and perioperative morbidity are described.

RESULTS

Patients (1396) were propensity matched into two equal groups (ERAS vs non-ERAS). No significant difference was observed for age, Charlson Comorbidity Index, American Society of Anesthesiologists score, body mass index, sex, operative approach, and surgery duration. Median length of stay in ERAS and non-ERAS groups was 3 and 5 days (P < .001). Mean pain scores were lower in the ERAS group, measured at discharge from the postanesthesia unit (P < .001), on postoperative day 1 (P = .002) and postoperative day 2 (P = .02) but were identical on discharge.

CONCLUSIONS

This ERAS protocol was validated in a similar patient population but at a different hospital. ERAS implementation was associated with an improved length of stay and pain scores similar to the original study. Different than most retrospective studies, propensity score matching ensured that groups were evenly matched. To our knowledge, this study is the only ERAS validation study in a propensity-matched cohort of patients undergoing elective colorectal surgery.

Enhanced recovery after pulmonary surgery

The concept of surgical recovery encompasses the entire perioperative phase of the patient, beginning with the preoperative baseline and culminating in the long-term rehabilitation of the patient in the post-operative phase. Enhanced recovery pathways (ERPs) aim to encompass all phase of the patient trajectory, including the preoperative, perioperative, and postoperative management of surgical patients. While significant literature exists on standardizing and optimizing the perioperative phase, standardizing the pre and post-operative phases remains a topic of debate. Furthermore, with regards to pulmonary surgery, the available data on enhanced recovery remains limited, with no consensus on which components to include within the ERP. The difficulty in identifying specific factors to include within a pathway is in part due to the lack of representative metrics of recovery. Secondly, the strength of ERPs usually lies in the agglomeration of multiple components rather than the individual components themselves. This review provides a brief review on current developments in ERPs in pulmonary surgery, emphasizing novel components in the pre and post-operative care of patients. Furthermore, we discuss the limitations of current metrics used to study recovery, and what steps can be taken to direct future studies that aim to enhance patient recovery after pulmonary surgery.

Process measures facilitate maturation of pediatric enhanced recovery protocols

BACKGROUND/PURPOSE

The role of process measures used to predict quality in pediatric colorectal surgery enhanced recovery protocols has not been described. The purpose of this study was to demonstrate the feasibility of abstracting and monitoring process measures over protocol improvement iteration.

METHODS

Patients enrolled in the Pediatric Colorectal Enhanced Recovery After Surgery pathway at our institution were grouped by stage of implementation. We used a quality improvement database to compare multistage enhanced recovery process measures and 30-day patient outcomes.

RESULTS

We identified 58 surgical patients with 28(48%) cases enrolled in the pathway. There was increased use of regional anesthesia techniques in pathway patients (83% versus 20%, p < 0.001). All preoperative process measures clinically improved between early and full implementation. Improvements included a dramatic increase in formal preoperative education (56% versus 0%, p = 0.004) and administration of preoperative medication (p = 0.025). Overall, 12 (21%) patients experienced postoperative complications, which were similarly distributed between implementation groups. Readmissions were highest during the early implementation phase (40%, p = 0.029). Children in the late implementation group experienced fewer complications, which clinically correlated with process measure adherence.

CONCLUSIONS

Process measures complement outcome measures in assessing quality and effectiveness of a pediatric colorectal recovery protocol. Adherence to processes may reduce complications.

LEVEL OF EVIDENCE

Treatment study, Level III.

An enhanced recovery after surgery program for video-assisted thoracoscopic surgery anatomical lung resections is cost-effective

Background

Enhanced recovery after surgery (ERAS) programs have been reported to decrease complications and shorten hospital stays after lung resections, but their implementation requires time and financial investment with dedicated staff. The aim of this study was to evaluate the clinical and economic outcomes of video-assisted thoracoscopic surgery (VATS) anatomical pulmonary resections before and after implementation of an ERAS program.

Methods

The first 50 consecutive patients undergoing VATS lobectomy or segmentectomy for malignancy after implementation of an ERAS program were compared with 50 consecutive patients treated before its introduction. The ERAS protocol included preoperative counseling, reduced preoperative fasting with concomitant carbohydrate loading, avoidance of premedication, standardized surgery, anesthesia and postoperative analgesia, early removal of chest tube, nutrition and mobilization. Length of stay, readmissions and cardio-pulmonary complications within 30 days were compared. Total costs were collected for each patient and a cost-minimization analysis integrating ERAS-specific costs was performed.

Results

Both groups were similar in terms of demographics and surgical characteristics. The ERAS group had significantly shorter postoperative length of stay (median: 4 vs. 7 days, P<0.0001), decreased pulmonary complications (16% vs. 38%; P=0.01) and decreased overall post-operative complications (24% vs. 48%, P=0.03). One patient in each group was readmitted and there was no 30-day mortality. ERAS-specific costs were calculated at €729 per patient including the clinical nurse and database costs. Average total hospitalization costs were significantly lower in ERAS group (€15,945 vs. €20,360, P<0.0001), mainly due to lower costs during the post-operative period (€7,449 vs. €11,454, P<0.0001) in comparison with the intra-operative period (€8,496 vs. €8,906, P=0.303). Cost-minimization analysis showed a mean saving in the ERAS group of €3,686 per patient.

Conclusions

An ERAS program for VATS anatomical lung resection is cost-effective and is associated with a lower complication rate and a shorter postoperative hospitalization.

Labelling as reference Centre of GRACE (Groupe francophone de Réhabilitation Améliorée après ChirurgiE) for colorectal surgery: its impact on the implementation of enhanced recovery programme at the University Hospital of Liège

BACKGROUND

Enhanced recovery programme (ERP) has been used in our hospital since 2005 for selected colorectal surgeries. Since October 2015, after labelling as GRACE reference centre, we included all patients scheduled for elective colorectal surgery in this programme. We assessed the impact of our labelling on the implementation of ERP.

METHODS

Results of our first 100 patients entered in the GRACE database were analyzed: length of stay, complications, readmission, adherence to the protocol. These results are compared to those of the last 100 patients undergoing colorectal surgery before our labelling.

RESULTS

Patients' characteristics in both groups were similar. The complications rate was similar in both groups. The global length of hospital stay was 4 [5] days vs. 8.5 [8] (median [IQR]), respectively after and before labelling; p < .001. The duration of hospitalization for the different subgroups (age, surgical approach, types of surgery) were significantly shorter after our labelling (respectively: p < .001, p < .01, and p < .05).

CONCLUSIONS

Our results demonstrate that labelling as reference centre increases the efficiency of the implementation of ERP. The fact that all subgroups of patients benefit from ERP must encourage inclusion of all patients undergoing elective colorectal surgery in ERP.

Enhanced recovery after surgery program in older patients undergoing gynaecologic oncological surgery is feasible and safe

BACKGROUND

Enhanced Recovery After Surgery Programs (ERP) include multimodal approaches of perioperative patient's clinical pathways designed to achieve early recovery after surgery and a decreased length of hospital stay (LOS). By allowing patients to return rapidly to their everyday surroundings, older patients are those who could take the greatest benefit from ERP. This is the first study to date to assess feasibility and safety of ERP on older patients undergoing gynaecologic oncological surgery.

METHODS

Data were prospectively collected between December 2015 and September 2017 at the Institut Paoli-Calmettes, a French comprehensive cancer centre. All the patients included in the study were referred for hysterectomy and/or pelvic or para-aortic lymphadenectomy for gynaecological cancer. The primary objective was to achieve similar LOS in patients ≥70 years old compared to younger patients without increasing the proportion of complications and readmission rates. A binary (LOS < or ≥ 2 days) logistic regression was built, including age, Charlson score, BMI, ASA score, oncological indication, surgical procedures and surgical approaches. G8 score was estimated for all the ≥70 years old patients.

RESULTS

Of a total of 329 patients, 75 were ≥70 years old and 254 were <70. Except a disparity in oncological indications with a higher proportion of endometrial cancer in the ≥70 years old group (56% vs. 27%; p < 0.01), there were no differences in patient's characteristics and surgical procedures. Age ≥ 70 years was associated with a longer LOS (means, 3.88 vs. 3.11 days; p = 0.024) only in univariate analysis. Considering the logistic regression, age was no longer associated with LOS. Total hysterectomy with pelvic lymphadenectomy and ASA score ≥ 3 were independently associated with longer LOS while mini-invasive techniques were associated with a shorter LOS. Morbidities and readmissions occurred respectively in 23% and 8% of the total population without any difference between the two groups. In the ≥70 years old population, G8 score was not predictive of LOS, morbidities or readmissions.

CONCLUSION

Although it is already widely accepted that ERP improves early recovery, our study shows that ERP for patients over 70 years of age undergoing gynaecologic oncological surgery is as safe and feasible as on younger patients.

Reducing morbidity and complications after major head and neck cancer surgery: the (future) role of enhanced recovery after surgery protocols

PURPOSE OF REVIEW

To review the development and the benefits of enhanced recovery after surgery (ERAS) protocols in non-head and neck disciplines and to describe early implementation efforts in major head and neck surgeries.

RECENT FINDINGS

Several groups have adopted ERAS protocols for major head and neck surgery and demonstrated its feasibility and effectiveness.

SUMMARY

There is growing evidence that clinical and financial outcomes for patients undergoing major head and neck surgery rehabilitation can be significantly improved by standardizing preoperative, intraoperative, and postoperative treatment protocols. Current experience is limited to single centers. A future goal is to broaden the adoption of ERAS in head and neck surgical oncology to include national and international collaboration, data sharing, and learning.

Acute kidney injury following implementation of an enhanced recovery after surgery (ERAS) protocol in colorectal surgery

PURPOSE

Fluid management within Enhanced Recovery After Surgery (ERAS) protocols is designed to maintain a euvolemic state avoiding the negative sequelae of hypervolemia or hypovolemia. We sought to determine the effect of a recent ERAS protocol implementation on kidney function and on the incidence of postoperative acute kidney injury (AKI).

METHODS

A total of 132 elective colorectal resections performed using our ERAS protocol were compared to a propensity-matched group prior to ERAS implementation. Fluid balance, urine output, creatinine, and blood urea nitrogen (BUN) were recorded for all patients, and the incidence of AKI was determined according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria.

RESULTS

Implementation of our ERAS protocol decreased average postoperative length of hospital stay (5.5 vs 7.7 days, p < 0.0001) and time to return of bowel function (2.5 vs 4.1 days, p < 0.0001). The rate of postoperative AKI increased following implementation of the protocol (11.4 vs 2.3%, p < 0.0001). However, by the time of discharge, the average creatinine of ERAS patients who had experienced AKI had returned to their preoperative baseline values (p = 0.9037). Significant univariate predictors of AKI in ERAS patients were longer operative times (p < 0.01) and the diagnosis of diverticulitis (p < 0.01). Within our ERAS patients, AKI was associated with a prolonged postoperative length of hospital stay (p < 0.01).

CONCLUSIONS

Despite the proven benefits of the Enhanced Recovery After Surgery (ERAS) protocols, care should be taken during protocol implementation to monitor for and to prevent acute kidney injury.

Immunonutrition for patients undergoing surgery for head and neck cancer

BACKGROUND

Patients with head and neck cancer are often malnourished. Surgery for such cancers is complex and may be undertaken after a course of radiotherapy. As a result, patients may have postoperative complications such as fistulae and wound infections, as well as more generalised infections such as pneumonia. One possible way to enhance recovery, and reduce the incidence of these complications, is by improving nutrition. Nutritional formulas that deliver basic nutrients as well as amino acids (arginine and glutamine), ribonucleic acid (RNA) and/or lipids (omega-3 fatty acids) are known as immunonutrition.

OBJECTIVES

To assess the effects of immunonutrition treatment, compared to standard feeding, on postoperative recovery in adult patients undergoing elective (non-emergency) surgery for head and neck cancer.

SEARCH METHODS

The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL); PubMed; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 14 February 2018.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) comparing immunonutrition given either preoperatively, postoperatively or perioperatively to adult patients (18 years of age or older) undergoing an elective surgical procedure for head and neck cancer, compared with a control group receiving either standard polymeric nutritional supplements or no supplements.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. The primary outcomes were: length of hospital stay (days), wound infection, fistula formation and adverse events/tolerance of feeds, as defined by trial authors. Secondary outcomes were: all-cause mortality and postoperative complications (as defined by trial authors). We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics.

MAIN RESULTS

We included 19 RCTs (1099 participants). The mean age of participants ranged from 47 to 66 years. Most studies (12/19) had fewer than 25 patients in each treatment group. Most studies (16/19) used immunonutrition formulas containing arginine, but there was variation in the actual products and amounts used, and in the length of intervention postoperatively. Follow-up time for outcome measurement varied considerably across studies, ranging from five days to greater than or equal to 16 months.Primary outcomesWe found no evidence of a difference in the length of hospital stay (mean difference -2.5 days, 95% confidence interval (CI) -5.11 to 0.12; 10 studies, 757 participants; low-quality evidence). Similarly, we found no evidence of an effect of immunonutrition on wound infection (risk ratio (RR) 0.94, 95% CI 0.70 to 1.26; 12 studies, 812 participants; very low-quality evidence). Fistula formation may be reduced with immunonutrition; the absolute risks were 11.3% and 5.4% in the standard care and immunonutrition groups, with a RR of 0.48 (95% CI 0.27 to 0.85; 10 studies, 747 participants; low-quality evidence). We found no evidence of a difference in terms of tolerance of feeds ('adverse events') between treatments (RR 1.33, 95% CI 0.86 to 2.06; 9 studies, 719 participants; very low-quality evidence).Secondary outcomesWe found no evidence of a difference between treatments in all-cause mortality (RR 1.33, 95% CI 0.48 to 3.66; 14 studies, 776 participants; low-quality evidence). Other postoperative complications such as pneumonia and urinary tract infections were not commonly reported.

AUTHORS' CONCLUSIONS

The risk of postoperative fistula formation may be reduced with immunonutrition, but we found no evidence of an effect of immunonutrition on any of the other outcomes that we assessed. The studies included in this review were generally small or at high risk of bias (or both). We judged the overall quality of the evidence to be low for the outcomes length of hospital stay and all-cause mortality, and very low for wound infection and adverse events. Further research should include larger, better quality studies.

"The Longest Way Round Is The Shortest Way Home": An Overhaul of Surgical Ward Rounds

Background

Ward rounds, a keystone of hospital surgical practice, have recently been under the spotlight. Poor-quality ward rounds can lead to a greater number of adverse events, thereby cascading to an increased financial strain on our already burdened healthcare systems. Faced with mounting pressures from both outside and inside health organizations, concerted efforts are required to restore it back into prominence where it can no longer take a backseat to the other duties of a surgeon.

Methods

The nucleus of this narrative review is derived from an extensive literature search on surgical ward rounds.

Results

In this review, we focus on the need for reforms, current characteristics of surgical ward rounds, obstacles encountered by competing interests and proposed solutions in delivery of effective ward rounds that can meet with newly laid guidelines.

Conclusion

Ward rounds should be standardized and prioritized to improve patient care.

Implementation Science in Perioperative Care

There is a 17-year gap between the initial publication of scientific evidence and its uptake into widespread practice in health care. The field of implementation science (IS) emerged in the 1990s as an answer to this "evidence-to-practice gap." In this article, we present an overview of implementation science, focusing on the application of IS principles to perioperative care. We describe opportunities for additional training and discuss strategies for funding and publishing IS work. The objective is to demonstrate how IS can improve perioperative patient care, while highlighting perioperative IS studies and identifying areas in need of additional investigation.

Enhanced recovery for thoracic surgery in the elderly

PURPOSE OF REVIEW

Both surgical workload and the age of those patients being considered for radial pulmonary resection are increasing. Enhanced recovery programmes are now well established in most surgical disciplines and are increasingly reported in thoracic procedures. This review will discuss the relevant principles of these programmes as applied to an increasing elderly population.

RECENT FINDINGS

Elderly patients undergoing less radial surgical resections without lymphadenectomy have comparable outcomes to those undergoing classical curative treatment. Patients require careful assessment and self-reported quality of life metrics or function may be a better marker of outcome than static measures such as lung function. Hypotension, low values for bispectral index and low anaesthetic gas mean alveolar concentration values are common and independent predictors of mortality in the elderly. Paravertebral blockade is preferred to epidural anaesthesia because of a more favourable side-effect profile and comparable efficacy. As yet no robust work has examined the efficacy of an integrated enhanced recovery programme in thoracic surgery.

SUMMARY

Elderly patients are suitable for enhanced recovery programmes but these must be tailored to individual circumstance. Further work is required to comprehensively assess their value in a modern healthcare setting.

Laparoscopic colorectal surgery and Enhanced Recovery After Surgery (ERAS) program: Experience with 200 cases from a single Italian center

There is increasing evidence that minimally invasive techniques associated with Enhanced Recovery After Surgery (ERAS) protocols reduce surgery-related stress and promote faster recovery after major colorectal surgery. As a single tertiary referral center for colorectal surgery, our aim was to analyze the effects of our ERAS protocol on a heterogeneous population undergoing laparoscopic colorectal surgery.Prospectively collected data from 283 patients undergoing laparoscopic colorectal resection at the Division of General and Hepatobiliary Surgery, University of Verona Hospital Trust, between March 2014 and March 2018 were retrospectively analyzed. Patients' adherence to pre-, intra-, and postoperative ERAS protocol items together with surgical short-term outcomes such as morbidity, mortality, length of hospital stay, and readmission rate was considered.The study protocol was approved by the Ethics Committee of Azienda Ospedaliera Universitaria Integrata di Verona (CRINF-1034 CESC).During the study period, 200 patients met the inclusion criteria and were enrolled in the ERAS protocol. In this series, 34% of patients were aged 70 years or older. Rectal resections represented 26% of all cases, with stoma formation performed in 14.5% of patients. Despite such procedural heterogeneity, good short-term results were obtained: by postoperative day (POD) 2, 58.5% of patients had full return of bowel function, while 63.5% and 88% achieved regular soft diet intake and autonomous walking, respectively. Median (range) length of hospital stay was 5.5 days (2-40) with 71% of patients being discharged by POD 6. No postoperative mortality was recorded, and the rate of major complications was 3.5%. During the study period, 6 patients required redo surgery (3%) and 5 patients required rehospitalization within 30 days (2.5%).This study analyzing the results of the fast-track program in our first 200 cases confirms the feasibility and safety of ERAS protocol application within a heterogeneous population undergoing laparoscopic colonic and rectal resection for benign and malignant diseases.

Evaluation of an enhanced recovery protocol on patients having radical cystectomy for bladder cancer

INTRODUCTION

Enhanced recovery after surgery (ERAS) protocols are multimodal perioperative care protocols that are designed to shorten recovery time and reduce complication rates.^1,2 An ERAS protocol was implemented in the Saskatoon Health region for radical cystectomy patients in 2013. This study evaluates the safety and efficacy of the protocol for patients having radical cystectomy for bladder cancer.

METHODS

Length of stay, early in-hospital complication rates, 30-day readmission rates, age, and gender were collected for patients seen for bladder cancer requiring radical cystectomy in Saskatoon between January 2007 and December 2016. Of these patients, 176 were pre-ERAS implementation (control group) and 84 were post-ERAS implementation (experimental group). The data from each variable was compared between the groups using a Z-test.

RESULTS

There was no significant difference in age or gender of patients between the groups. Average length of stay pre-ERAS was 14.25±14.57 days, which is significantly longer than the post-ERAS average of 10.91±8.56 days (p=0.043). There was no significant difference in 30-day readmission rate (19.87% pre-ERAS vs. 19.05% post-ERAS; p=0.873) or complication rate (51.7% pre-ERAS vs. 46.4% post-ERAS; p=0.425).

CONCLUSIONS

The implementation of an ERAS protocol for radical cystectomy reduces length of stay, with no effect on early complication rates or 30-day readmission rates. This indicates that the protocol is safe for patients when compared to previous practices and is an effective means of reducing length of stay.

Measuring In-Hospital Recovery After Colorectal Surgery Within a Well-Established Enhanced Recovery Pathway: A Comparison Between Hospital Length of Stay and Time to Readiness for Discharge

BACKGROUND

Hospital length of stay is often used as a measure of in-hospital recovery but may be confounded by organizational factors. Time to readiness for discharge may provide a superior index of recovery.

OBJECTIVE

The purpose of this study was to contribute evidence for the construct validity of time to readiness for discharge and length of stay as measures of in-hospital recovery after colorectal surgery in the context of a well-established enhanced recovery pathway.

DESIGN

This was an observational validation study designed according to the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist.

SETTINGS

The study was conducted at a university-affiliated tertiary hospital.

PATIENTS

A total of 100 consecutive patients undergoing elective colorectal resection (mean age = 65 y; 57% men; 81% laparoscopic) who participated in a randomized controlled trial were included.

MAIN OUTCOME MEASURES

We tested a priori hypotheses that length of stay and time-to-readiness for discharge are longer in patients undergoing open surgery, with lower physical status, with severe comorbidities, with postoperative complications, undergoing rectal surgery, who are older (≥75 y), who have a new stoma, and who have inflammatory bowel disease.

RESULTS

Median time-to-readiness for discharge and length of stay were both 3 days. For both measures, 6 of 8 construct validity hypotheses were supported (hypotheses 1 and 4-8).

LIMITATIONS

The use of secondary data from a randomized controlled trial (risk of selection bias) was a limitation. Results may not be generalizable to institutions where patient care is not equally structured.

CONCLUSIONS

This study contributes evidence to the construct validity of time-to-readiness for discharge and length of stay as measures of in-hospital recovery within enhanced recovery pathways. Our findings suggest that length of stay can be a less resource-intensive and equally construct-valid index of in-hospital recovery compared with time-to-readiness for discharge. Enhanced recovery pathways may decrease process-of-care variances that impact length of stay, allowing more timely discharge once discharge criteria are achieved.

Randomized Controlled Trial of Extended Perioperative Counseling in Enhanced Recovery After Colorectal Surgery

BACKGROUND

Enhanced recovery after surgery programs reduce the length of hospital stay in patients who undergo elective colorectal resection, but the reasons for this reduction are not well understood.

OBJECTIVE

The aim of this randomized controlled trial was to assess the impact of extended perioperative counseling in treatment groups that were otherwise the same with respect to enhanced recovery after surgery criteria.

DESIGN

Patients eligible for open or laparoscopic colorectal resection were randomly assigned to extended counseling (repeated information and guidance by a dedicated nurse) or standard counseling.

SETTINGS

This study was conducted at a single institution.

PATIENTS

Patients (n = 164) were randomly assigned to enhanced recovery after surgery plus extended counseling (n = 80) or enhanced recovery after surgery with standard counseling (n = 84).

MAIN OUTCOME MEASURES

The primary end point was the total length of hospital stay. Discharge criteria were defined. Secondary end points were postoperative complications, postoperative length of hospital stay, readmission rate, and mortality.

RESULTS

Total hospital stay was significantly shorter among patients randomly assigned to enhanced recovery after surgery plus extended counseling (median 5 (range 2-29) days vs 7 (range 2-39) days, p < 0.001). The 2 treatment groups differed in adherence to the elements of postoperative enhanced recovery after surgery such as mobilization and total oral intake. The 2 treatment groups did not differ in overall, major, and minor morbidity; reoperation rate; readmission rate; and 30-day mortality.

LIMITATIONS

The main limitation of this study was the absence of blinding.

CONCLUSIONS

Perioperative information and guidance were important factors in enhanced recovery after surgery care and were associated with a significantly shorter length of hospital stay. Our findings suggest that perioperative counseling enables patients to comply with the elements of postoperative enhanced recovery after surgery and thereby reduces the length of hospital stay. This study was registered with ClinicalTrials.gov (NCT01610726). See Video Abstract at http://links.lww.com/DCR/A505.

Enhanced recovery after cesarean delivery

Enhanced recovery after surgery is a concept initially developed for patients undergoing colorectal surgery but has been adopted by other surgical specialties with similar positive outcomes. The adoption of enhanced recovery after surgery in the obstetric patient population is rapidly gaining popularity. This review highlights perioperative interventions that should be considered in an enhanced recovery after surgery protocol for women undergoing cesarean delivery.

A matter of perspective - Objective versus subjective outcomes in the assessment of quality of recovery

Current post-operative recovery assessment exists as a dichotomy, maintaining objectivity whilst providing relevance to patient-centred care. Both objective and subjective measures are utilised in modern recovery assessment and are best viewed as complimentary. At institutional and provider levels, performance indicators are utilised as surrogates for quality of recovery but only if these indicators are assessed in the clinical context from which they are derived. Patient-reported outcomes prioritise the patient's perspective of symptoms and care, which are the most important aspects at the time of assessment but are limited by their susceptibility to response shift and recall bias. Ideally, quality of recovery is assessed using objective measures in concert with measures of clinical complexity and in parallel with patient-reported outcomes.

How to implement an enhanced recovery programme after colorectal surgery?

INTRODUCTION

Although the concept of enhanced recovery after surgery was introduced more than 20 years ago, its implementation in daily practice still remains difficult.

RESULTS

This article addresses bottlenecks and barriers to the development of enhanced recovery programme (ERP). Barriers to the implementation are multifactorial and are raised by the different actors of these programmes: surgeons, anaesthetists, nurses, patients. Solutions and steps that must be respected to succeed in introducing ERP in an hospital are proposed.

CONCLUSIONS

Large-scale implementation of ERP continues to face mainly lack of trust and communication. Solutions exist and are based particularly on team work and interdisciplinary collaboration.

Perioperative management of patients with coronary artery disease undergoing non-cardiac surgery: Summary from the French Society of Anaesthesia and Intensive Care Medicine 2017 convention

This review summarises the specific stakes of preoperative, intraoperative, and postoperative periods of patients with coronary artery disease undergoing non-cardiac surgery. All practitioners involved in the perioperative management of such high cardiac risk patients should be aware of the modern concepts expected to decrease major adverse cardiac events and improve short- and long-term outcomes. A multidisciplinary approach via a functional heart team including anaesthesiologists, cardiologists and surgeons must be encouraged. Rational and algorithm-guided management of those patients should be known and implemented from preoperative to postoperative period.

Meta-Analysis of the Effect of Gum Chewing After Gynecologic Surgery

OBJECTIVE

To describe the scientific evidence related to gum chewing to reduce ileus after gynecologic surgery.

DATA SOURCES

A literature search was performed using Ovid Medline, Embase, Cochrane Library, CINAHL, Scopus, and Web of Science databases.

STUDY SELECTION

Inclusion criteria included randomized controlled trials (RCTs) on the use of gum chewing after gynecologic surgery in which the main outcomes measured were time to first flatus, time to defecation, and length of hospital stay.

DATA EXTRACTION

Data on authors, country, randomization method, the type of disease, surgical and anesthetic methods, sample characteristics such as age and body mass index, gum chewing program, and study results were extracted from selected articles.

DATA SYNTHESIS

Of 493 publications, eight RCTs conducted between 2013 and 2017 involving 1,077 women were included in our meta-analysis. Weighted mean differences (WMDs) with 95% confidence intervals were calculated for the eight studies with the use of Cochrane Review Manager Version 5.3 (RevMan; 2014). The pooled results showed that gum chewing was superior to no gum chewing, with a reduction in WMD for time to first flatus of -6.20 hours (95% confidence interval [CI] [-9.51, -2.88]), WMD for time to first defecation of -9.03 hours (95% CI [-14.02, -4.04]), and WMD for length of hospital stay of -0.36 days (95% CI [-0.72, -0.01]).

CONCLUSION

Gum chewing significantly reduced the time to first flatus and defecation after gynecologic surgery and should be recommended by health care providers.
