Effects of Nutritional Prehabilitation, With and Without Exercise, on Outcomes of Patients Who Undergo Colorectal Surgery: A Systematic Review and Meta-analysis

Towards a common definition of surgical prehabilitation: a scoping review of randomised trials

BACKGROUND

There is no universally accepted definition for surgical prehabilitation. The objectives of this scoping review were to (1) identify how surgical prehabilitation is defined across randomised controlled trials and (2) propose a common definition.

METHODS

The final search was conducted in February 2023 using MEDLINE, Embase, PsycINFO, Web of Science, CINAHL, and Cochrane. We included randomised controlled trials (RCTs) of unimodal or multimodal prehabilitation interventions (nutrition, exercise, and psychological support) lasting at least 7 days in adults undergoing elective surgery. Qualitative data were analysed using summative content analysis.

RESULTS

We identified 76 prehabilitation trials of patients undergoing abdominal (n=26, 34%), orthopaedic (n=20, 26%), thoracic (n=14, 18%), cardiac (n=7, 9%), spinal (n=4, 5%), and other (n=5, 7%) surgeries. Surgical prehabilitation was explicitly defined in more than half of these RCTs (n=42, 55%). Our findings consolidated the following definition: 'Prehabilitation is a process from diagnosis to surgery, consisting of one or more preoperative interventions of exercise, nutrition, psychological strategies and respiratory training, that aims to enhance functional capacity and physiological reserve to allow patients to withstand surgical stressors, improve postoperative outcomes, and facilitate recovery.'

CONCLUSIONS

A common definition is the first step towards standardisation, which is needed to guide future high-quality research and advance the field of prehabilitation. The proposed definition should be further evaluated by international stakeholders to ensure that it is comprehensive and globally accepted.

The impact of goal-directed prehabilitation therapy on functional capacity in patients undergoing hepatobiliary and pancreatic surgery: A randomized clinical trial

BACKGROUND

Emerging evidence has supported the idea that goal-directed prehabilitation is a promising approach to boost functional capacity in preoperative patients. However, its usefulness has not been tested in the hepatobiliary and pancreatic fields. The objective of this trial was to investigate the efficacy of goal-directed prehabilitation for improving functional capacity in patients who were planned to undergo major hepatobiliary and pancreatic operations.

METHODS

This assessor-blinded, parallel-arm, randomized clinical trial recruited patients who were scheduled for major hepatobiliary and pancreatic surgeries for malignancy. Patients were randomly allocated into the step goal-directed prehabilitation group as the test group and into the conventional prehabilitation group as the control group. Patients in the goal-directed prehabilitation group participated in a walking prehabilitation program with an intergrading goal of the step count. Patients in the conventional prehabilitation group received standard physical and nutritional prehabilitation. The primary outcome was change in the 6-minute walking distance, which ranged from the time before starting prehabilitation (baseline) to the time after completing prehabilitation (immediately before surgery).

RESULTS

Among 180 randomized patients, 144 patients were included in the primary analysis (73 patients in the conventional prehabilitation group and 71 patients in the goal-directed prehabilitation group). The mean change in the 6-minute walking distance was 27 meters in the conventional prehabilitation group and 31 meters in the goal-directed prehabilitation group (P = .633).

CONCLUSION

In patients undergoing major hepatobiliary and pancreatic surgeries for malignancies, a goal-directed prehabilitation program did not result in a significantly greater increase in functional capacity than did conventional prehabilitation.

Integrated impact of multiple body composition parameters on overall survival in gastrointestinal or genitourinary cancers: A descriptive cohort study

BACKGROUND

This study aimed to evaluate if combining low muscle mass with additional body composition abnormalities, such as myosteatosis or adiposity, could improve survival prediction accuracy in a large cohort of gastrointestinal and genitourinary malignancies.

METHODS

In total, 2015 patients with surgically-treated gastrointestinal or genitourinary cancer were retrospectively analyzed. Skeletal muscle index, skeletal muscle radiodensity, and visceral/subcutaneous adipose tissue index were determined. The primary outcome was overall survival determined by hospital records. Multivariate Cox hazard models were used to identify independent predictors for poor survival. C-statistics were assessed to quantify the prognostic capability of the models with or without incorporating body composition parameters.

RESULTS

Survival curves were significantly demarcated by all 4 measures. Skeletal muscle radiodensity was associated with non-cancer-related deaths but not with cancer-specific survival. The survival outcome of patients with low skeletal muscle index was poor (5-year OS; 65.2%), especially when present in combination with low skeletal muscle radiodensity (5-year overall survival; 50.2%). All examined body composition parameters were independent predictors of lower overall survival. The model for predicting overall survival without incorporating body composition parameters had a c-index of 0.68 but increased to 0.71 with the inclusion of low skeletal muscle index and 0.72 when incorporating both low skeletal muscle index and low skeletal muscle radiodensity/visceral adipose tissue index/subcutaneous adipose tissue index.

CONCLUSION

Patients exhibiting both low skeletal muscle index and other body composition abnormalities, particularly low skeletal muscle radiodensity, had poorer overall survival. Models incorporating multiple body composition prove valuable for mortality prediction in oncology settings.

Advanced Lung Cancer Inflammation Index: A Novel Comprehensive Biomarker of Host Status for Patients with Metastatic Colorectal Cancer

Numerous biomarkers that reflect host status have been identified for patients with metastatic colorectal cancer (mCRC). However, there has been a paucity of biomarker studies that comprehensively indicate body composition, nutritional assessment, and systemic inflammation status. The advanced lung cancer inflammation index (ALI), initially introduced as a screening tool for patients with non-small-cell lung cancer in 2013, emerges as a holistic marker encompassing all body composition, nutritional status, and systemic inflammation status. The index is calculated by the simple formula: body mass index × albumin value / neutrophil-to-lymphocyte ratio. Given its accessibility in routine clinical practice, the ALI has exhibited promising clinical utility in prognosticating outcomes for patients with multiple types of cancer. In this review, we focus on the significance of host status and the clinical applicability of the ALI in the treatment and management of patients with malignancies, including mCRC. We also suggest its potential in guiding the formulation of treatment strategies against mCRC and outline future perspectives.

Nutritional Prehabilitation in Patients Undergoing Abdominal Surgery-A Narrative Review

Malnutrition plays a crucial role as a risk factor in patients undergoing major abdominal surgery. To mitigate the risk of complications, nutritional prehabilitation has been recommended for malnourished patients and those at severe metabolic risk. Various approaches have been devised, ranging from traditional short-term conditioning lasting 7-14 days to longer periods integrated into a comprehensive multimodal prehabilitation program. However, a significant challenge is the considerable heterogeneity of nutritional interventions, leading to a lack of clear, synthesizable evidence for specific dietary recommendations. This narrative review aims to outline the concept of nutritional prehabilitation, offers practical recommendations for clinical implementation, and also highlights the barriers and facilitators involved.

Effect of nutrition-based prehabilitation on the postoperative outcomes of patients with esophagogastric cancer undergoing surgery: A systematic review and meta-analysis

BACKGROUND

Meta-analyses have primarily focused on the effects of exercise-based prehabilitation on postoperative outcomes and ignored the role of nutritional intervention. In this study, we filled this gap by investigating the effect of nutrition-based prehabilitation on the postoperative outcomes of patients who underwent esophagectomy and gastrectomy.

METHODS

Five electronic databases, namely, PubMed, the Web of Science, Embase, Cochrane Library, and CINAHL, were searched. Adults diagnosed with esophagogastric cancer who were scheduled to undergo surgery and had undergone uni- or multimodal prehabilitation, with at least a week of mandatory nutritional intervention, were included. Forest plots were used to extract and visualize the data from the included studies. The occurrence of any postoperative complication was considered the primary endpoint.

RESULTS

Eight studies met the eligibility criteria, with five randomized controlled trials (RCTs) and three cohort studies. In total, 661 patients were included. Any prehabilitation, that is, unimodal (only nutrition) and multimodal prehabilitation, collectively decreased the risk of any postoperative complication by 23% (95% confidence interval [CI] = 0.66-0.90). A similar effect was exclusively observed for multimodal prehabilitation (risk ratio [RR] = 0.78, 95% CI = 0.66-0.93); however, it was not significant for unimodal prehabilitation. Any prehabilitation significantly decreased the length of hospital stay (LOS) (weighted mean difference = -0.77, 95% CI = -1.46 to -0.09).

CONCLUSIONS

Nutrition-based prehabilitation, particularly multimodal prehabilitation, confers protective effects against postoperative complications after esophagectomy and gastrectomy. Our findings suggest that prehabilitation slightly decreases LOS; however, the finding is not clinically significant. Therefore, additional rigorous RCTs are warranted for further substantiation.

Outcomes reported in randomised trials of surgical prehabilitation: a scoping review

BACKGROUND

Heterogeneity of reported outcomes can impact the certainty of evidence for prehabilitation. The objective of this scoping review was to systematically map outcomes and assessment tools used in trials of surgical prehabilitation.

METHODS

MEDLINE, EMBASE, PsychInfo, Web of Science, CINAHL, and Cochrane were searched in February 2023. Randomised controlled trials of unimodal or multimodal prehabilitation interventions (nutrition, exercise, psychological support) lasting at least 7 days in adults undergoing elective surgery were included. Reported outcomes were classified according to the International Society for Pharmacoeconomics and Outcomes Research framework.

RESULTS

We included 76 trials, mostly focused on abdominal or orthopaedic surgeries. A total of 50 different outcomes were identified, measured using 184 outcome assessment tools. Observer-reported outcomes were collected in 86% of trials (n=65), with hospital length of stay being most common. Performance outcomes were reported in 80% of trials (n=61), most commonly as exercise capacity assessed by cardiopulmonary exercise testing. Clinician-reported outcomes were included in 78% (n=59) of trials and most frequently included postoperative complications with Clavien-Dindo classification. Patient-reported outcomes were reported in 76% (n=58) of trials, with health-related quality of life using the 36- or 12-Item Short Form Survey being most prevalent. Biomarker outcomes were reported in 16% of trials (n=12) most commonly using inflammatory markers assessed with C-reactive protein.

CONCLUSIONS

There is substantial heterogeneity in the reporting of outcomes and assessment tools across surgical prehabilitation trials. Identification of meaningful outcomes, and agreement on appropriate assessment tools, could inform the development of a prehabilitation core outcomes set to harmonise outcome reporting and facilitate meta-analyses.

Health professionals' perceptions of prehabilitation before haematopoietic cell transplantation to optimise candidacy in older adults

PURPOSE

Haematologic malignancies for the most part are diseases of the elderly. Haematopoietic stem cell transplantation (HSCT) remains the only potentially curative strategy for many patients but carries substantial morbidity and mortality risks, particularly in frail or co-morbid patients. Pre-transplant optimisation of key targets through prehabilitation may have significant clinical impact.

METHODS

We utilised qualitative methodology (semi-structured interviews) to gain insights and understanding of the perceptions of medical, nursing and allied health professionals towards prehabilitation before haematopoietic cell transplantation to optimise candidacy in older adults. Thematic analysis was performed using a qualitative descriptive approach completed in duplicate by two researchers.

RESULTS

Between August and October 2023, eleven health professionals participated from four large cancer centres across the island of Ireland (n = 3 consultant haematologists, n = 7 specialist haematology nurses and n = 1 senior haematology physiotherapist). Four major themes were identified. The themes comprehensive biopsychosocial care and increasing demand for transplant in older patients highlight the unique challenges impacting older adults who receive HSCT. The multimodality pathways of care theme highlights the heterogeneity of treatment pathways across different clinical sites and disease types. This has implications for the prehabilitation: logistics and benefits theme, which indicated strong support for prehabilitation but emphasised that implementation must consider national reach and context.

CONCLUSIONS

There is broad national multidisciplinary interest in the development of prehabilitation programmes for patients being considered for transplant. Our results will inform the development of services in this area in consideration of national reach, malignancy-specific pathways and the unique factors associated with older age.

Effectiveness of Prehabilitation Modalities on Postoperative Outcomes Following Colorectal Cancer Surgery: A Systematic Review of Randomised Controlled Trials

BACKGROUND

Postoperative morbidity in patients undergoing curative colorectal cancer surgery is high. Prehabilitation has been suggested to reduce postoperative morbidity, however its effectiveness is still lacking.

OBJECTIVE

The aim of this study was to investigate the effectiveness of prehabilitation in reducing postoperative morbidity and length of hospital stay in patients undergoing colorectal cancer surgery.

METHODS

A comprehensive electronic search was conducted in the CINAHL, Cochrane Library, Medline, PsychINFO, AMED, and Embase databases from inception to April 2023. Randomised controlled trials testing the effectiveness of prehabilitation, including exercise, nutrition, and/or psychological interventions, compared with usual care in patients undergoing colorectal cancer surgery were included. Two independent review authors extracted relevant information and assessed the risk of bias. Random-effect meta-analyses were used to pool outcomes, and the quality of evidence was assessed using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) guidelines.

RESULTS

A total of 23 trials were identified (N = 2475 patients), including multimodal (3 trials), exercise (3 trials), nutrition (16 trials), and psychological (1 trial) prehabilitation. There was moderate-quality evidence that preoperative nutrition significantly reduced postoperative infectious complications (relative risk 0.65, 95% confidence interval [CI] 0.45-0.94) and low-quality evidence on reducing the length of hospital stay (mean difference 0.87, 95% CI 0.17-1.58) compared with control. A single trial demonstrated an effect of multimodal prehabilitation on postoperative complication.

CONCLUSION

Nutrition prehabilitation was effective in reducing infectious complications and length of hospital stay. Whether other multimodal, exercise, and psychological prehabilitation modalities improve postoperative outcomes after colorectal cancer surgery is uncertain as the current quality of evidence is low.

Bowel endometriosis: Surgical customization is demanding

Bowel endometriosis is the most common form of severe deep endometriosis. Surgery is an option in case of infertility and/or chronic pain or in the presence of a stenotic lesion. Clinical examination and preoperative imaging must provide an identity card of the lesion so that customized surgery can be proposed. The primary objective of this tailor-made surgery will always be to preserve the organ. The surgeon then has three options: shaving, discoid resection and segmental resection. The more extensive the resection, the greater the risk of severe short- and long-term complications. Surgery must therefore be adapted to the patient's specific situation and needs. Moreover, personalized care must extend beyond surgery. It must begin before the operation, preparing the patient for the operation like an athlete before a race, and continue afterwards by adapting the follow-up to the surgery performed.

Sarcopenia as a Preoperative Risk Stratification Tool among Older Adults with Inflammatory Bowel Disease

Sarcopenia, defined as a loss of muscle mass and function, is a physiologic factor that has been implicated as a predictor of adverse postoperative outcomes in many older adult populations. However, data related to sarcopenia in older adults with inflammatory bowel disease (IBD) remain limited. Older adults with IBD are particularly vulnerable to adverse postoperative outcomes, in part, due to muscle depletion from systemic inflammation, malnutrition, and reduced physical activity. However, few patients undergo routine muscle evaluation as a part of preoperative assessment. Moreover, cut-off values for measures of sarcopenia in the literature are modeled after non-IBD populations. The lack of standardized measures and values for sarcopenia in the IBD patient population has led to heterogenous findings and a paucity of preoperative risk stratification tools. Therefore, we aim to explore the scope of sarcopenia as a preoperative risk stratification tool among older adults with IBD.

Oral nutritional supplements improve clinical outcomes and are cost-effective for hospitalized patients in China

OBJECTIVE

This study assessed the therapeutic benefits and modeled the cost-effectiveness of oral nutritional supplements (ONS) in China.

METHODS

Data were collected from 27 152 adult inpatients between January 1, 2018, and December 31, 2020. Propensity score matching was used for balancing the baseline characteristics between the ONS group and non-ONS group. A decision-tree model was developed to assess the cost-effectiveness of ONS for patients with nutritional risk, and the incremental cost-effectiveness ratio was the metric to determine the most cost-effective strategy. One-way sensitivity and probabilistic sensitivity analyses were conducted to assess the model's stability. In addition, subgroup analysis was conducted based on clinical characteristics. Differences in clinical outcomes between the groups were compared using Student's t test, Mann-Whitney U test, or chi-square test.

RESULTS

The ONS group displayed significantly lower levels of prealbumin, albumin, hemoglobin, and BMI than the non-ONS group at admission. The incidence of malignant tumors, intestinal obstruction, and inflammatory bowel disease was significantly higher in the ONS group than the non-ONS group. The ONS group had a significantly higher effective rate than the non-ONS group (51.7% versus 50.3%, P < 0.05). Analysis of the decision-tree model revealed that the ONS group experienced an increase in cost of 19 850.96 yuan but achieved an additional 1.3406 effectiveness rate, resulting in an incremental cost-effectiveness ratio of 14 807.51, which fell below China's 2020 per capita gross domestic product of 71 965 yuan. Sensitivity analysis further confirmed the robustness of the model.

CONCLUSIONS

ONS are demonstrated a high rate of efficacy, although patients currently using ONS are typically in a severe disease state. In addition, ONS is cost-effective. We suggest that the reimbursement coverage of ONS be expanded to include in-hospital patients who are at high nutritional risk.

Patients' and carers' views on research priorities in prehabilitation for cancer surgery

INTRODUCTION

The views of patients and carers are important for the development of research priorities. This study aimed to determine and compare the top research priorities of cancer patients and carers with those of multidisciplinary clinicians with expertise in prehabilitation.

MATERIALS AND METHODS

This cross-sectional study surveyed patients recovering from cancer surgery at a major tertiary hospital in Sydney, Australia, and/or their carers between March and July 2023. Consenting patients and carers were provided a list of research priorities according to clinicians with expertise in prehabilitation, as determined in a recent International Delphi study. Participants were asked to rate the importance of each research priority using a 5-item Likert scale (ranging from 1 = very high research priority to 5 = very low research priority).

RESULTS

A total of 101 patients and 50 carers participated in this study. Four areas were identified as research priorities, achieving consensus of highest importance (> 70% rated as "high" or "very high" priority) by patients, carers, and clinical experts. These were "optimal composition of prehabilitation programs" (77% vs. 82% vs. 88%), "effect of prehabilitation on surgical outcomes" (85% vs. 90% vs. 95%), "effect of prehabilitation on functional outcomes" (83% vs. 86% vs. 79%), and "effect of prehabilitation on patient reported outcomes" (78% vs. 84% vs. 79%). Priorities that did not reach consensus of high importance by patients despite reaching consensus of highest importance by experts included "identifying populations most likely to benefit from prehabilitation" (70% vs. 76% vs. 90%) and "defining prehabilitation core outcome measures" (66% vs. 74% vs. 87%). "Prehabilitation during neoadjuvant therapies" reached consensus of high importance by patients but not by experts or carers (81% vs. 68% vs. 69%).

CONCLUSION

This study delineated the primary prehabilitation research priorities as determined by patients and carers, against those previously identified by clinicians with expertise in prehabilitation. It is recommended that subsequent high-quality research and resource allocation be directed towards these highlighted areas of importance.

PERIOPERATIVE CARE IN DIGESTIVE SURGERY: THE ERAS AND ACERTO PROTOCOLS - BRAZILIAN COLLEGE OF DIGESTIVE SURGERY POSITION PAPER

BACKGROUND

The concept introduced by protocols of enhanced recovery after surgery modifies perioperative traditional care in digestive surgery. The integration of these modern recommendations components during the perioperative period is of great importance to ensure fewer postoperative complications, reduced length of hospital stay, and decreased surgical costs.

AIMS

To emphasize the most important points of a multimodal perioperative care protocol.

METHODS

Careful analysis of each recommendation of both ERAS and ACERTO protocols, justifying their inclusion in the multimodal care recommended for digestive surgery patients.

RESULTS

Enhanced recovery programs (ERPs) such as ERAS and ACERTO protocols are a cornerstone in modern perioperative care. Nutritional therapy is fundamental in digestive surgery, and thus, both preoperative and postoperative nutrition care are key to ensuring fewer postoperative complications and reducing the length of hospital stay. The concept of prehabilitation is another key element in ERPs. The handling of crystalloid fluids in a perfect balance is vital. Fluid overload can delay the recovery of patients and increase postoperative complications. Abbreviation of preoperative fasting for two hours before anesthesia is now accepted by various guidelines of both surgical and anesthesiology societies. Combined with early postoperative refeeding, these prescriptions are not only safe but can also enhance the recovery of patients undergoing digestive procedures.

CONCLUSIONS

This position paper from the Brazilian College of Digestive Surgery strongly emphasizes that the implementation of ERPs in digestive surgery represents a paradigm shift in perioperative care, transcending traditional practices and embracing an intelligent approach to patient well-being.

Attitudes and perceptions of cancer patients and healthcare providers towards prehabilitation: A thematic synthesis

PURPOSE

Prehabilitation, which is the process of enhancing functional capacity before undergoing surgery or other treatments, has been shown to improve cancer patients' outcomes. Patient and healthcare provider attitudes and perceptions are essential factors in the successful implementation of prehabilitation. The purpose of this systematic review is to synthesize qualitative evidence and explore the barriers and facilitators to prehabilitation implementation.

METHODS

From the earliest available date to October 2023, 7 databases (PubMed, Web of Science, Cochrane Library, Embase, CINAHL, PsycINFO, and MEDLINE) were searched for a systematic review. Data were extracted, thematically analysed, and mapped onto the Capability, Opportunity, and Motivation Model of Behaviour (COM-B). The Critical Appraisal Skills Programme (CASP) tool was used to assess the quality of the studies.

RESULTS

A total of 26 studies were included, involving 377 patients, 51 caregivers, and 156 healthcare providers. 16 factors were identified and mapped onto the COM-B model: reflective/automatic motivation, physical/social opportunity, physical/ psychological capability.

CONCLUSIONS

Patients and healthcare provides identified a lack of reflective motivation and physical opportunities as the most significant barriers to engagement in prehabilitation. Personalized approaches, social support, and healthcare providers' engagement are key factors for prehabilitation. Future research should focus on developing effective interventions to enhance the uptake and sustainability of prehabilitation.

Barriers and facilitators to the implementation of prehabilitation for elderly frail patients prior to elective surgery: a qualitative study with healthcare professionals

BACKGROUND

Prehabilitation aims to enhance functional capacity before surgery, minimise complications and achieve a better postoperative outcome. This can be particularly useful for older, frail patients to better tolerate surgery. The aim of this study was to identify what barriers and facilitators healthcare professionals in Germany experienced in the implementation and delivery of the multimodal prehabilitation programme "PRAEP-GO" for (pre-)frail adults aged 70 years and older to inform the implementation of prehabilitation into standard care.

METHODS

A nested descriptive qualitative study was conducted using semi-structured face-to-face interviews with healthcare professionals involved in the PRAEP-GO trial from the Berlin and Brandenburg region in Germany. Transcripts were analysed using Kuckartz' qualitative content analysis. Results were interpreted and synthesised using the Consolidated Framework for Implementation Research, a theoretical framework to allow their application to a more general context.

RESULTS

A total of 14 interviews were conducted. Seven therapists (physio-, ergo-, sports therapy), five physicians and two employees from other professions with mainly administrative and organisational tasks in the project. All identified barriers and facilitating factors could be assigned to the themes of organisation, prehabilitation, cooperation and communication between healthcare professionals and with patients. Much optimisation potential was found regarding organisational aspects, e.g. addressing perceived staff shortages and optimising the patient pathway. Furthermore, it became apparent that communication and cooperation between professionals but also with patients need to be improved. More evidence regarding prehabilitation should be provided to convince professionals more. Prehabilitation should be multimodal and individualised, including the programme duration. Officially introducing prehabilitation into standard care would facilitate its delivery.

DISCUSSION

These findings underscore the fact that successful implementation of prehabilitation programmes, such as PRAEP-GO, requires sufficient organisational infrastructure, human resources, access to knowledge, an adaptable and individualised programme design as well as good communication among professionals and with patients. The transferability of the findings is limited by the absence of nutritionists and resulting overrepresentation of other therapists in the sample. To further convince professionals and patients of the concept of prehabilitation, more research is needed to build a solid evidence base that will ensure greater awareness and, thus, more motivation and cooperation among professionals and patients.

Multicomponent perioperative interventions to improve outcomes for frail patients: a systematic review

BACKGROUND

Preoperative frailty is associated with increased risk of adverse outcomes. In 2017, McIsaac and colleagues' systematic review found that few interventions improved outcomes in this population and evidence was low-quality. We aimed to systematically review the evidence for multicomponent perioperative interventions in frail patients that has emerged since McIsaac et al.'s review.

METHODS

PUBMED, EMBASE, Cochrane, and CINAHL databases were searched for English-language studies published since January 1, 2016, that evaluated multicomponent perioperative interventions in patients identified as frail. Quality was assessed using the National Institute of Health Quality Assessment Tool. A narrative synthesis of the extracted data was conducted.

RESULTS

Of 2835 articles screened, five studies were included, all of which were conducted in elective oncologic gastrointestinal surgical populations. Four hundred and thirteen patients were included across the five studies and the mean/median age ranged from 70.1 to 87.0 years. Multicomponent interventions were all applied in the preoperative period. Two studies also applied interventions postoperatively. All interventions addressed exercise and nutritional domains with variability in timing, delivery, and adherence. Multicomponent interventions were associated with reduced postoperative complications, functional deterioration, length of stay, and mortality. Four studies reported on patient-centred outcomes. The quality of evidence was fair.

CONCLUSIONS

This systematic review provides evidence that frail surgical patients undergoing elective oncologic gastrointestinal surgery may benefit from targeted multicomponent perioperative interventions. Yet methodological issues and substantial heterogeneity of the interventions precludes drawing clear conclusions regarding the optimal model of care. Larger, low risk of bias studies are needed to evaluate optimal intervention delivery, effectiveness in other populations, implementation in health care settings and ascertain outcomes of importance for frail patients and their carers.

Frailty Screening is Associated with Hospitalization and Decline in Quality of Life and Functional Status in Older Patients with Inflammatory Bowel Disease

BACKGROUND AND AIMS

Our goals were to study frailty screening in association with hospitalization and decline in quality of life [QoL] and functional status in older patients with inflammatory bowel diseases [IBD].

METHODS

This was a prospective multicentre cohort study in IBD patients ≥65 years old using frailty screening [G8 Questionnaire]. Outcomes were all-cause, acute, and IBD-related hospitalization, any infection, any malignancy, QoL [EQ5D-3L], and functional decline (Instrumental Activities of Daily Living [IADL]) during 18 months of follow-up. Confounders were age, IBD type, biochemical disease activity [C-reactive protein ≥10 mg/L and/or faecal calprotectin ≥250 µg/g], and comorbidity [Charlson Comorbidity Index].

RESULTS

Of 405 patients, with a median age of 70 years, 196 [48%] were screened as being at risk for frailty. All-cause hospitalizations occurred 136 times in 96 patients [23.7%], and acute hospitalizations 103 times in 74 patients [18.3%]. Risk of frailty was not associated with all-cause (adjusted hazard ratio [aHR] 1.5, 95% confidence interval [CI] 0.9-2.4), but was associated with acute hospitalizations [aHR 2.2, 95% CI 1.3-3.8]. Infections occurred in 86 patients [21.2%] and these were not associated with frailty. A decline in QoL was experienced by 108 [30.6%] patients, and a decline in functional status by 46 patients [13.3%]. Frailty screening was associated with a decline in QoL (adjusted odds ratio [aOR] 2.1, 95% CI 1.3-3.6) and functional status [aOR 3.7, 95% CI 1.7-8.1].

CONCLUSIONS

Frailty screening is associated with worse health outcomes in older patients with IBD. Further studies are needed to assess the feasibility and effectiveness of its implementation in routine care.

Preoperative nutrition therapy in people undergoing gastrointestinal surgery

BACKGROUND

Poor preoperative nutritional status has been consistently linked to an increase in postoperative complications and worse surgical outcomes. We updated a review first published in 2012.

OBJECTIVES

To assess the effects of preoperative nutritional therapy compared to usual care in people undergoing gastrointestinal surgery.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, three other databases and two trial registries on 28 March 2023. We searched reference lists of included studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of people undergoing gastrointestinal surgery and receiving preoperative nutritional therapy, including parenteral nutrition, enteral nutrition or oral nutrition supplements, compared to usual care. We only included nutritional therapy that contained macronutrients (protein, carbohydrate and fat) and micronutrients, and excluded studies that evaluated single nutrients. We included studies regardless of the nutritional status of participants, that is, well-nourished participants, participants at risk of malnutrition, or mixed populations. We excluded studies in people undergoing pancreatic and liver surgery. Our primary outcomes were non-infectious complications, infectious complications and length of hospital stay. Our secondary outcomes were nutritional aspects, quality of life, change in macronutrient intake, biochemical parameters, 30-day perioperative mortality and adverse effects.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodology. We assessed risk of bias using the RoB 1 tool and applied the GRADE criteria to assess the certainty of evidence.

MAIN RESULTS

We included 16 RCTs reporting 19 comparisons (2164 participants). Seven studies were new for this update. Participants' ages ranged from 21 to 79 years, and 62% were men. Three RCTs used parenteral nutrition, two used enteral nutrition, eight used immune-enhancing nutrition and six used standard oral nutrition supplements. All studies included mixed groups of well-nourished and malnourished participants; they used different methods to identify malnutrition and reported this in different ways. Not all the included studies were conducted within an Enhanced Recovery After Surgery (ERAS) programme, which is now current clinical practice in most hospitals undertaking GI surgery. We were concerned about risk of bias in all the studies and 14 studies were at high risk of bias due to lack of blinding. We are uncertain if parenteral nutrition has any effect on the number of participants who had a non-infectious complication (risk ratio (RR) 0.61, 95% confidence interval (CI) 0.36 to 1.02; 3 RCTs, 260 participants; very low-certainty evidence); infectious complication (RR 0.98, 95% CI 0.53 to 1.80; 3 RCTs, 260 participants; very low-certainty evidence) or length of hospital stay (mean difference (MD) 5.49 days, 95% CI 0.02 to 10.96; 2 RCTs, 135 participants; very low-certainty evidence). None of the enteral nutrition studies reported non-infectious complications as an outcome. The evidence is very uncertain about the effect of enteral nutrition on the number of participants with infectious complications after surgery (RR 0.90, 95% CI 0.59 to 1.38; 2 RCTs, 126 participants; very low-certainty evidence) or length of hospital stay (MD 5.10 days, 95% CI -1.03 to 11.23; 2 RCTs, 126 participants; very low-certainty evidence). Immune-enhancing nutrition compared to controls may result in little to no effect on the number of participants experiencing a non-infectious complication (RR 0.79, 95% CI 0.62 to 1.00; 8 RCTs, 1020 participants; low-certainty evidence), infectious complications (RR 0.74, 95% CI 0.53 to 1.04; 7 RCTs, 925 participants; low-certainty evidence) or length of hospital stay (MD -1.22 days, 95% CI -2.80 to 0.35; 6 RCTs, 688 participants; low-certainty evidence). Standard oral nutrition supplements may result in little to no effect on number of participants with a non-infectious complication (RR 0.90, 95% CI 0.67 to 1.20; 5 RCTs, 473 participants; low-certainty evidence) or the length of hospital stay (MD -0.65 days, 95% CI -2.33 to 1.03; 3 RCTs, 299 participants; low-certainty evidence). The evidence is very uncertain about the effect of oral nutrition supplements on the number of participants with an infectious complication (RR 0.88, 95% CI 0.60 to 1.27; 5 RCTs, 473 participants; very low-certainty evidence). Sensitivity analysis based on malnourished and weight-losing participants found oral nutrition supplements may result in a slight reduction in infections (RR 0.58, 95% CI 0.40 to 0.85; 2 RCTs, 184 participants). Studies reported some secondary outcomes, but not consistently. Complications associated with central venous catheters occurred in RCTs involving parenteral nutrition. Adverse events in the enteral nutrition, immune-enhancing nutrition and standard oral nutrition supplements RCTs included nausea, vomiting, diarrhoea and abdominal pain.

AUTHORS' CONCLUSIONS

We were unable to determine if parenteral nutrition, enteral nutrition, immune-enhancing nutrition or standard oral nutrition supplements have any effect on the clinical outcomes due to very low-certainty evidence. There is some evidence that standard oral nutrition supplements may have no effect on complications. Sensitivity analysis showed standard oral nutrition supplements probably reduced infections in weight-losing or malnourished participants. Further high-quality multicentre research considering the ERAS programme is required and further research in low- and middle-income countries is needed.

Outcome Heterogeneity in Prehabilitation Trials-Are We Comparing Apples and Oranges?

INTRODUCTION

Over the last decade, the number of prehabilitation randomised controlled trials (RCTs) has increased significantly. Therefore, this review aimed to describe the outcomes reported in prehabilitation RCTs in patients undergoing cancer surgery.

METHODS

A search was conducted in Embase, Allied and Complementary Medicine Database, The Cochrane Library, PsycINFO, MEDLINE, and Cumulated Index to Nursing and Allied Health Literature from inception to July 2021. We included RCTs evaluating the effectiveness of preoperative exercise, nutrition, and psychological interventions on postoperative complications and length of hospital stay in adult oncology patients who underwent thoracic and gastrointestinal cancer surgery. The verbatim outcomes reported in each article were extracted, and each outcome was assessed to determine whether it was defined and measured using a validated tool. Verbatim outcomes were grouped into standardized outcomes and categorized into domains. The quality of outcome reporting in each identified article was assessed using the Harman tool (score range 0-6, where 0 indicated the poorest quality).

RESULTS

A total of 74 RCTs were included, from which 601 verbatim outcomes were extracted. Only 110 (18.3%) of the verbatim outcomes were defined and 270 (44.9%) were labeled as either "primary" or "secondary" outcomes. Verbatim outcomes were categorized into 119 standardized outcomes and assigned into one of five domains (patient-reported outcomes, surgical outcomes, physical/functional outcomes, disease activity, and intervention delivery). Surgical outcomes were the most common outcomes reported (n = 71 trials, 95.9%). The overall quality of the reported outcomes was poor across trials (median score: 2.0 [IQR = 0.00-3.75]).

CONCLUSIONS

Prehabilitation RCTs display considerable heterogeneity in outcome reporting, and low outcome reporting quality. The development of standardized core outcome sets may help improve article quality and enhance the clinical utility of prehabilitation following cancer surgery.

The effect of prehabilitation on long-term survival and hospital admissions in older patients undergoing elective colorectal cancer surgery

INTRODUCTION

There is a growing body of evidence for a beneficial effect of prehabilitation on short-term outcomes after colorectal cancer (CRC) surgery in older patients. However, long-term effects on survival or hospital admissions have not been investigated. This study reports these long-term outcomes from a previously published observational cohort study.

METHODS

We compared patients ≥75 years who received elective CRC surgery in Reinier de Graaf Hospital before (2010-2013: standard care) and after implementation of a multimodal prehabilitation program (2014-2015; prehabilitation). With a six-year follow-up period, we analyzed survival using the Kaplan-Meier method and the occurrence of one or more hospital admissions using logistic regression analyses.

RESULTS

Overall, 137 patients were included in the standard care group and 86 patients in the prehabilitation group. There were no differences in patients, tumor and treatment characteristics. After six years, 51.1% in the standard care group and 59.3% in the prehabilitation group (p = 0.167) were still alive. When corrected for confounders in the prehabilitation group less patients had one or more hospital admissions during follow-up (odds ratio (OR) 0.43 (95% CI 0.24-0.77).

CONCLUSIONS

Unfortunately these limited historical cohorts did not allow for strong conclusions concerning long-time survival. However, after prehabilitation less patients had hospital admissions during follow up. Hopefully, this first study into the long-term effects of multimodal prehabilitation will trigger more future research.

Construction of individualised care programmes for patients with pancreatic cancer with postoperative weight-loss control based on the Delphi method: a cross-sectional study in China

BACKGROUND

At present, clinical nutritional care for patients with pancreatic cancer focuses more on the observation of the effect of enteral parenteral nutrition, and there is a lack of personalised care plans for weight-loss control. We used the Delphi method to construct a set of personalised nursing programmes to effectively control the rate of postoperative weight loss in patients with pancreatic cancer.

METHODS

This study was a cross-sectional investigation. Through literature analysis, literature review and data review, a personalised nursing plan for the postoperative weight-loss control in patients with pancreatic cancer was preliminarily developed. From October to December 2022, the Delphi method was adopted to conduct two questionnaires for 32 experts working in fields related to pancreatic diseases in Grade-A tertiary hospitals from four different departments. After statistical processing, the personalised nursing plan was determined according to the perceived level of importance, coefficient of variation, full score rate and recognition rate of the indicators.

RESULTS

The recovery rates of the two rounds of consultation were 93.75% and 100%, respectively, and the overall authority coefficient of the experts was 0.918, which represented 'authoritative'. In terms of importance, the coefficient of variation was 0-0.137; in terms of feasibility, the coefficient of variation ranged from 0.09 to 0.194. Finally, a scheme consisting of 36 entries in 8 dimensions was built. This programme is comprehensive in content, meets the nutritional diagnosis and treatment needs of patients in the stage of postoperative rehabilitation, provides relatively comprehensive nutritional assessment and support and has a robust system and feasibility.

CONCLUSIONS

The individualised nursing plan for patients with pancreatic cancer with postoperative weight-loss control based on the Delphi method is highly scientific and reliable and has positive significance.

The effectiveness of prehabilitation interventions on biopsychosocial and service outcomes pre and post upper gastrointestinal surgery: a systematic review

PURPOSE

This review synthesised the evidence for the effect of prehabilitation interventions on biopsychosocial and service outcomes.

MATERIALS AND METHODS

A systematic review was conducted. 10 databases were searched to December 2023. Prospective experimental studies exploring prehabilitation interventions in adults undergoing upper gastrointestinal surgery were included. Prehabilitation was any preoperative intervention to improve physical or psychological outcomes. Included studies required a comparator group or alternative preoperative intervention as well as baseline, presurgical and postoperative assessment points. Study quality was assessed using the Cochrane risk of bias tool (v.2). Data synthesis was narrative (SWiM guidance).

RESULTS

6028 studies were screened, with 25 studies included. Prehabilitation interventions were: inspiratory muscle training (five studies n = 450); exercise (nine studies n = 683); psychological (one study n = 400); and nutritional (ten studies n = 487). High quality studies showed preoperative improvements in impairments directly targeted by the interventions. Generally, these did not translate into functional or postoperative improvements, but multimodal interventions were more promising.

CONCLUSION

Current evidence supports prehabilitation as safe to preserve or improve preoperative function. Heterogeneity in outcomes and variable study quality means definitive conclusions regarding interventions are not yet possible, limiting implementation. Agreement of clinical outcomes and cost effectiveness evaluation is required.

Multimodal prerehabilitation for elderly patients with sarcopenia in colorectal surgery

Sarcopenia, which is characterized by progressive and generalized loss of skeletal muscle mass and strength, has been well described to be associated with numerous poor postoperative outcomes, such as increased perioperative mortality, postoperative sepsis, prolonged length of stay, increased cost of care, decreased functional outcome, and poorer oncological outcomes in cancer surgery. Multimodal prehabilitation, as a concept that involves boosting and optimizing the preoperative condition of a patient prior to the upcoming stressors of a surgical procedure, has the purported benefits of reversing the effects of sarcopenia, shortening hospitalization, improving the rate of return to bowel activity, reducing the costs of hospitalization, and improving quality of life. This review aims to present the current literature surrounding the concept of sarcopenia, its implications pertaining to colorectal cancer and surgery, a summary of studied multimodal prehabilitation interventions, and potential future advances in the management of sarcopenia.

'Effects of a home-based bimodal lifestyle intervention in frail patients with end-stage liver disease awaiting orthotopic liver transplantation': study protocol of a non-randomised clinical trial

INTRODUCTION

Patients with end-stage liver disease awaiting orthotopic liver transplantation (OLT) are generally classified as frail due to disease-related malnutrition and a progressive decline in musculoskeletal and aerobic fitness, which is associated with poor pre-OLT, peri-OLT and post-OLT outcomes. However, frailty in these patients may be reversable with adequate exercise and nutritional interventions.

METHODS AND ANALYSIS

Non-randomised clinical trial evaluating the effect of a home-based bimodal lifestyle programme in unfit patients with a preoperative oxygen uptake (VO2) at the ventilatory anaerobic threshold ≤13 mL/kg/min and/or VO2 at peak exercise ≤18 mL/kg/min listed for OLT at the University Medical Center Groningen (UMCG). The programme is patient tailored and comprises high-intensity interval and endurance training, and functional exercises three times per week, combined with nutritional support. Patients will go through two training periods, each lasting 6 weeks.The primary outcome of this study is the impact of the programme on patients' aerobic fitness after the first study period. Secondary outcomes include aerobic capacity after the second study period, changes in sarcopenia, anthropometry, functional mobility, perceived quality of life and fatigue, incidence of hepatic encephalopathy and microbiome composition. Moreover, number and reasons of intercurrent hospitalisations during the study and postoperative outcomes up to 12 months post OLT will be recorded. Finally, feasibility of the programme will be assessed by monitoring the participation rate and reasons for non-participation, number and severity of adverse events, and dropout rate and reasons for dropout.

ETHICS AND DISSEMINATION

This study was approved by the Medical Research Ethics Committee of the UMCG (registration number NL83612.042.23, August 2023) and is registered in the Clinicaltrials.gov register (NCT05853484). Good Clinical Practice guidelines and the principles of the Declaration of Helsinki will be applied. Results of this study will be submitted for presentation at (inter)national congresses and publication in peer-reviewed journals.

Preparing for and Not Waiting for Surgery

Cancer surgery is an essential treatment strategy but can disrupt patients' physical and psychological health. With worldwide demand for surgery expected to increase, this review aims to raise awareness of this global public health concern, present a stepwise framework for preoperative risk evaluation, and propose the adoption of personalised prehabilitation to mitigate risk. Perioperative medicine is a growing speciality that aims to improve clinical outcome by preparing patients for the stress associated with surgery. Preparation should begin at contemplation of surgery, with universal screening for established risk factors, physical fitness, nutritional status, psychological health, and, where applicable, frailty and cognitive function. Patients at risk should undergo a formal assessment with a qualified healthcare professional which informs meaningful shared decision-making discussion and personalised prehabilitation prescription incorporating, where indicated, exercise, nutrition, psychological support, 'surgery schools', and referral to existing local services. The foundational principles of prehabilitation can be adapted to local context, culture, and population. Clinical services should be co-designed with all stakeholders, including patient representatives, and require careful mapping of patient pathways and use of multi-disciplinary professional input. Future research should optimise prehabilitation interventions, adopting standardised outcome measures and robust health economic evaluation.

Cognitive Prehabilitation: How Can We Counter Neurocognitive Frailty?

Perioperative neurocognitive disorders are common and concerning complications in older adults undergoing surgery that can manifest as acute or chronic cognitive decline. It is hypothesized that cognitive prehabilitation can prepare the brain for the stress of surgery as for any other organ system. In this mini review we discuss the rationale for using cognitive prehabilitation, some of the interventions that have been assessed, and the effects of these interventions on postoperative cognition. PATIENT SUMMARY: Training the brain before surgery can potentially reduce the risk of cognitive decline after surgery in older adults. This mini review discusses some of the trials that examined how to train the brain before surgery and the results from these trials.

Prehabilitation in colorectal cancer surgery improves outcome and reduces hospital costs

INTRODUCTION

Increasing evidence suggests that multimodal prehabilitation programs reduce postoperative complication rates and length of stay. Nevertheless, prehabilitation is not standard care yet, also as financial consequences of such programs are lacking. Aim of this study was to analyse clinical outcomes and effects on hospital resources if prehabilitation is implemented for patients who are planned for colorectal surgery.

MATERIALS AND METHODS

Patients undergoing elective colorectal surgery and who received either prehabilitation or standard care between January 2017 and March 2022 in a regional Dutch hospital were included. Outcome parameters were length of hospital stay, 30-day postoperative complications, 30-day ICU admission, readmission rates and hospital costs.

RESULTS

A total of 196 patients completed prehabilitation whereas 390 patients received standard care. Lower overall complication rates (31 % vs 40 %, p = 0.04) and severe complication rates (20 % vs 31 %, p = 0.01) were observed in the prehabilitation group compared to standard care. Length of stay was shorter in the prehabilitation group (mean 5.80 days vs 6.71 days). In hospital cost savings were €1109 per patient, while the calculated investment for prehabilitation was €969.

CONCLUSION

Implementation of a multimodal prehabilitation program in colorectal surgery reduces postoperative complication rates, length of stay and hospital costs.

Effect of Preoperative Lifestyle Management and Prehabilitation on Postoperative Capability of Colorectal Cancer Patients: A Systematic Review and Meta-Analysis

BACKGROUND

The surgical intervention serves as the paramount and prevalent remedy for individuals afflicted with colorectal malignancies, with the significance of perioperative stewardship and convalescence being indisputable. Prehabilitation coupled with preoperative lifestyle modulation has demonstrated efficacy in patients subjected to certain classifications of abdominal procedures. However, the evidence pertaining to its impact on those battling colorectal cancer remains equivocal.

METHODS

A meta-analysis, grounded in pairwise contrast, of randomized controlled trials (RCTs) was orchestrated, coupled with a systematic review, to probe the efficacy of preoperative lifestyle modulation and prehabilitation on patients' postoperative functionality and recuperation. An exhaustive exploration of 8 electronic databases and trial registries was undertaken to encompass all pertinent RCTs disseminated in English or Chinese from January 2012 through December 2022. Employing a random-effects model, we evaluated parameters such as the 6-minute walk test (6 MWT), complications, quality of life (QoL), aggregate and postoperative duration of hospitalization (tLHS and postLHS), and healthcare expenditure (HExp) for postoperative patients.

RESULTS

A total of 28 RCTs were incorporated into the systematic review and meta-analysis. Relative to conventional preoperative care, rehabilitation or preoperative lifestyle management was found to enhance postoperative 6MWT (SMD 1.30, 95% CI 0.30 to 2.29) and diminish the complication rate (OR 0.53, 95% CI 0.40 to 0.69). Nonetheless, no significant discrepancies were observed in QoL (SMD 1.81, 95% CI -0.26 to 3.87), tLHS (SMD -0.26, 95% CI -0.68 to 0.15), and postLHS (SMD -1.46, 95% CI -3.12 to 0.20) between the groups. HExp could not be evaluated due to a lack of sufficient data for synthesis. Most pooled outcomes exhibited significant heterogeneity, urging a cautious interpretation. Subgroup analysis revealed that nutritional interventions could mitigate the incidence of complications, and preoperative exercise could improve tLHS and postLHS. A combined approach of physical, nutritional, and psychological intervention or prehabilitation proved superior to any single intervention in enhancing postoperative capabilities.

CONCLUSION

This meta-analysis delineated the efficacy of preoperative interventions on postoperative capabilities in patients with colorectal cancer, thereby offering evidence for clinical practice. It was concluded that preoperative interventions are unequivocally beneficial for postoperative functional recovery and the reduction of complication rates in patients with colorectal cancer. Nonetheless, the acquisition of more high-level evidence is still necessitated to further ascertain the effectiveness of this strategy for other patient groups and to establish its best practices. The heterogeneity in the pooled outcomes underlines the need for future studies to be more uniform in their design and reporting, which would facilitate more robust and reliable meta-analyses.

Patient and Provider Experiences With a Digital App to Improve Compliance With Enhanced Recovery After Surgery (ERAS) Protocols: Mixed Methods Evaluation of a Canadian Experience

BACKGROUND

Of all the care provided in health care systems, major surgical interventions are the costliest and can carry significant risks. Enhanced Recovery After Surgery (ERAS) is a bundle of interventions that help improve patient outcomes and experience along their surgical journey. However, given that patients can be overwhelmed by the multiple tasks that they are expected to follow, a digital application, the ERAS app, was developed to help improve the implementation of ERAS.

OBJECTIVE

The objective of this work was to conduct a thorough assessment of patient and provider experiences using the ERAS app.

METHODS

Patients undergoing colorectal or gynecological oncology surgery at 2 different hospitals in the province of Alberta, Canada, were invited to use the ERAS app and report on their experiences using it. Likewise, care providers were recruited to participate in this study to provide feedback on the performance of this app. Data were collected by an online survey and using qualitative interviews with participants. NVivo was used to analyze qualitative interview data, while quantitative data were analyzed using Excel and SPSS.

RESULTS

Overall, patients found the app to be helpful in preparation for and recovery after surgery. Patients reported having access to reliable unbiased information regarding their surgery, and the app provided them with clarity of actions needed along their surgical journey and enhanced the self-management of their care. Clinicians found that the ERAS app was easy to navigate, was simple for older adults, and has the potential to decrease unnecessary visits and phone calls to care providers. Overall, this proof-of-concept study on the use of a digital health app to accompany patients during their health care journey has shown positive results.

CONCLUSIONS

This is an important finding considering the massive investment and interest in promoting digital health in health care systems around the world.

One-Year Follow-Up after Multimodal Prehabilitation Interventions in Radical Cystectomy

Multimodal prehabilitation is the process of enhancing physiological, nutritional, and psychological resilience to increase patients' functional capacity before major cancer surgery and aims to empower the patient to withstand the pending stress of major surgery and ultimately to improve long-term outcomes. The effect of physical prehabilitation to counteract the physical decline in surgical cancer patients has been documented; however, long-term results have not yet been published. This follow-up study aims to evaluate 1-year results on the efficacy of physical prehabilitation after bladder cancer surgery. The efficacy of prehabilitation was measured over the course of 1 year in 107 patients randomized to (1) pre- and rehabilitation or (2) standard care divided by n = 50 in the intervention (I) and n = 57 in the standard group (S). Physical function was measured by muscle leg power, and nutritional status was expressed with handgrip strength. Prehabilitation in major bladder cancer surgery can significantly improve physical function with 19.8 Watt/kg (p = 0.04), lean body mass (p = 0.047) and body cell mass (p = 0.03), and regained nutritional status one year after surgery. The results demonstrate that the restoration of physical function is vital to a full recovery.

Effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer: a systematic review and meta-analysis

PURPOSE

To evaluate the effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer.

METHODS

We conducted a systematic search of the PubMed, Embase, CINAHL, Web of Science, and Cochrane Library (CENTRAL) databases from database inception to May 5, 2023, for randomized controlled trials (RCTs) and cohort studies that investigated prehabilitation in the context of esophagogastric cancer. A random-effects model was used for meta-analysis.

RESULTS

We identified 2,994 records and eventually included 12 studies (6 RCTs and 6 cohort studies) with a total of 910 patients. According to random-effects pooled estimates, prehabilitation reduced the incidence of all complications (RR = 0.79, 95% CI: 0.66 to 0.93, P = 0.006), pulmonary complications (RR = 0.61, 95% CI: 0.47 to 0.79, P = 0.0002), and severe complications (RR = 0.63, 95% CI: 0.47 to 0.84, P = 0.002), and shortened the length of stay (MD = -1.92, 95% CI: -3.11 to -0.73, P = 0.002) compared to usual care. However, there were no statistically significant differences in 30-day readmission rates or in-hospital mortality. Subgroup analysis showed that multimodal prehabilitation was effective in reducing the risk of all complications and severe complications, while unimodal prehabilitation was not.

CONCLUSIONS

Our findings suggested that prehabilitation may be beneficial in reducing postoperative complications and length of stay. We recommend preoperative prehabilitation to improve postoperative outcomes and hasten recovery following esophagogastric cancer surgery, and multimodal prehabilitation seems to be more advantageous in reducing complications. However, further studies are needed to confirm these results.

Perioperative Malnutrition

CASE SUMMARY

A 61-year-old man presented with penetrating Crohn's ileocolitis and neoterminal ileal fibrostenotic stricture. He developed an anastomotic leak after a redo ileocolic resection and now has a chronic low-output enterocutaneous fistula. He was transferred from an outside institution for further management and is currently without Crohn's disease (CD)-related medical therapy. The fistula output is 25 to 50 mL/day of GI contents. His weight dropped by 25 pounds in 6 months after surgery with a current BMI of 19.1, albumin of 2.0 g/dL, and hemoglobin of 9.7 g/dL. During a 3-month period, he was optimized for surgery with local wound care, initiation of infliximab, and nutritional support with exclusive enteral nutrition (EEN). He gained 9 pounds (BMI 20.4). Albumin improved to 3.4 g/dL and hemoglobin to 12.1 g/dL. He underwent a successful open takedown of the enterocutaneous fistula with ileocolic anastomosis.

Muscle quality, not quantity, is associated with outcome after colorectal cancer surgery

INTRODUCTION

Emerging evidence suggests that deconditioned patients benefit most from prehabilitation before colorectal cancer surgery. So far, selecting patients with poor muscle status and high perioperative risk remains challenging. Therefore, this study evaluates the potential of the CT-derived Skeletal Muscle Index (SMI), representing muscle mass, and of the Muscle Radiation Attenuation (MRA), a measure of muscle quality, for risk stratification in colorectal cancer patients.

METHODS

In this retrospective, single-center observational study, 207 patients with resection of colorectal adenocarcinoma between January 2016 and December 2020 were included. The Charlson comorbidity index (CCI), postoperative complications, length of hospital stay, and survival were recorded. Data were analyzed using multivariable linear, logistic, and Cox proportional hazards regression models adjusted for age, sex, BMI, CCI, neoadjuvant therapy, tumor stage, and surgery type.

RESULTS

An increase of the MRA was associated with fewer postoperative complications (anastomotic leakage and pneumonia) and lesser severity according to the Clavien-Dindo classification, shorter hospital stays, and prolonged survival (Hazard ratio: 0.63 [95%CI: 0.49-0.81], p < 0.001). No relevant associations were found between the SMI and postoperative complications, length of hospital stay, or survival.

CONCLUSION

The easy-to-raise MRA serves as a more reliable tool than the SMI for identifying high-risk patients with poor muscle status before colorectal surgery. Those patients may benefit most from prehabilitation, which has to be proven in future interventional trials.

Prognostic Nutritional Index Is a Predictive Marker for Health-Related Quality of Life in Patients with Adult Degenerative Scoliosis

Our aim was to ascertain whether the prognostic nutritional index (PNI), could predict the health-related quality of life (HRQOL) in patients with adult degenerative scoliosis (ADS) undergoing corrective surgery. We conducted a retrospective analysis of consecutive patients diagnosed with ADS between January 2013 and June 2021. Three nutritional parameters were employed for analysis (PNI, anemia, and hypoalbuminemia). We utilized the Scoliosis Research Society-22 (SRS-22) questionnaire and the Oswestry Disability Index (ODI) questionnaire to assess clinical outcomes. Following the epidemiology guidelines, we presented results from three different models: the crude model, minimally adjusted model, and fully adjusted model. A total of 316 ADS patients were included in the statistical analysis. There was no significant difference in sagittal plane radiographic parameters between the two groups. After adjusting for important confounding factors, PNI was an independent predictor of postoperative HRQOL. Specifically, for each one-unit increase in PNI, there was an approximately 20% higher likelihood of patients achieving a better HRQOL. Furthermore, we did not observe an association between hemoglobin levels or albumin levels and HRQOL. In this study, PNI has been demonstrated to be correlated with the postoperative HRQOL in patients with ADS undergoing corrective surgery.

Home-based prehabilitation improves physical conditions measured by ergospirometry and 6MWT in colorectal cancer patients: a randomized controlled pilot study

PURPOSE/BACKGROUND

Prehabilitation aims to improve physical condition in the preoperative period and, therefore, decrease the loss of cardiopulmonary capacity postoperatively, with the aim of reducing complications and promoting an early recovery. This study aims to evaluate the impact of home-based prehabilitation on the physical condition of patients treated surgically for colorectal cancer.

METHODS

A prospective and randomized clinical study was conducted on 60 patients during two periods from October 2018 to February 2019 and from September 2019 to September 2020, in a single university hospital. Patients were randomized into two study groups (30 per group): prehabilitation vs. standard care. Changes in physical condition, measured at diagnosis, the day before surgery, and at 6-8 weeks after surgery using the cardiopulmonary exercise testing (CPET) and the 6-minute walk test (6MWT) were evaluated.

RESULTS

Prehabilitation reduced postoperative complications (17.4% vs. 33.3%, p = 0.22) and hospital stay (5.74 vs. 6.67 days, p = 0.30). 6MWT showed a significant improvement in the prehabilitation group (+78.9 m). Six weeks after surgery, prehabilitation showed a significant improvement in the 6MWT (+68.9 m vs. -27.2 m, p = 0.01). Significant differences were also observed in the ergospirometry between the diagnosis and postoperative study (+0.79 METs vs. -0.84 METs, p = 0.001). A strong correlation was observed between CPET and 6MWT (0.767 (p < 0.001)).

CONCLUSION

Home prehabilitation achieved lower overall postoperative complications than standard care and reached significant improvements in 6MWT and CET. A strong correlation was observed between CET and 6MWT, which allows validation of 6MWT as a valid and reliable measure of functional exercise capacity in colorectal patients when other, more specific and expensive tests are not available.

Total Psoas Area is a Measure for Deconditioning in Colorectal Surgery Patients

INTRODUCTION

Physical fitness is an important prognostic indicator for surgical outcomes. An objective measure of deconditioning is needed to determine patient fitness. This study aims to describe a methodology to standardize psoas measurements and correlate them with postoperative outcomes.

METHODS

After obtaining IRB approval, the ACS-NSQIP database was queried for patients over 18 years, undergoing colectomies for non-trauma indications from 1/1/2013 to 12/31/2018. Upon CT imaging, the psoas muscle was identified at the lumbosacral joint. Imaging software calculated the total cross-sectional area of the left and right psoas muscle and was normalized by dividing by height squared to achieve our Total Psoas Index (TPI) in cm2/m2.

RESULTS

1173 patients met study criteria; all had TPI calculated. A TPI equal to or below the gender-specific 25th percentile defined sarcopenia. In total, 151 females (24.6%) and 137 males (24.5%) were classified as sarcopenic. TPI was significantly associated with multiple NSQIP 30-day outcomes and mortality in our study population.

CONCLUSIONS

Measuring TPI at the lumbosacral joint is an appropriate method for determining sarcopenia.

Barriers and Facilitators of Surgical Prehabilitation Adherence from the Patient Perspective: a Mixed Method Study

BACKGROUND

Adherence to prehabilitation is crucial for optimal benefit, but reasons for low adherence to home-based programs remain unexplored. Our aim was to identify and explore barriers and facilitators to prehabilitation adherence among patients undergoing abdominal surgery.

METHODS

Nested in a single-center randomized controlled trial on prehabilitation (Perioperative Optimization With Enhanced Recovery (POWER)), this study had an explanatory sequential design with a connect integration. Patients randomized to the intervention arm were included in the quantitative analysis, and a subset of them was invited for a semi-structured interview. The exposure was the frequency of barriers to physical activity and healthy eating, and the outcome was adherence to those components of prehabilitation. Logistic or linear regression was used as appropriate.

RESULTS

Among 133 participants in the intervention arm, 116 (87.2%) completed the initial survey ((56.9% women, median age 61 years old (IQR 49.0; 69.4)). The most frequent barriers to exercise and healthy eating were medical issues (59%) and lack of motivation (31%), respectively. There was no significant association between the barriers to physical activity score and adherence to this component of the program (OR 0.89, 95% CI 0.78-1.02, p=0.09). Higher barriers to healthy eating scores were associated with lower Mediterranean diet scores pre- and post-intervention (coef.: -0.32, 95% CI: -0.49; -0.15, p<0.001; and coef.: -0.27, 95% CI: -0.47; -0.07, p=0.01, respectively). Interviews with 15 participants revealed that participating in prehabilitation was a motivator for healthy eating and exercising through goal setting, time-efficient workouts, and promoting self-efficacy.

CONCLUSIONS

We identified key barriers to be addressed and facilitators to be leveraged in future prehabilitation programs.

Impact of preoperative uni- or multimodal prehabilitation on postoperative morbidity: meta-analysis

BACKGROUND

Postoperative complications occur in up to 43% of patients after surgery, resulting in increased morbidity and economic burden. Prehabilitation has the potential to increase patients' preoperative health status and thereby improve postoperative outcomes. However, reported results of prehabilitation are contradictory. The objective of this systematic review is to evaluate the effects of prehabilitation on postoperative outcomes (postoperative complications, hospital length of stay, pain at postoperative day 1) in patients undergoing elective surgery.

METHODS

The authors performed a systematic review and meta-analysis of RCTs published between January 2006 and June 2023 comparing prehabilitation programmes lasting ≥14 days to 'standard of care' (SOC) and reporting postoperative complications according to the Clavien-Dindo classification. Database searches were conducted in PubMed, CINAHL, EMBASE, PsycINFO. The primary outcome examined was the effect of uni- or multimodal prehabilitation on 30-day complications. Secondary outcomes were length of ICU and hospital stay (LOS) and reported pain scores.

RESULTS

Twenty-five studies (including 2090 patients randomized in a 1:1 ratio) met the inclusion criteria. Average methodological study quality was moderate. There was no difference between prehabilitation and SOC groups in regard to occurrence of postoperative complications (OR = 1.02, 95% c.i. 0.93 to 1.13; P = 0.10; I2 = 34%), total hospital LOS (-0.13 days; 95% c.i. -0.56 to 0.28; P = 0.53; I2 = 21%) or reported postoperative pain. The ICU LOS was significantly shorter in the prehabilitation group (-0.57 days; 95% c.i. -1.10 to -0.04; P = 0.03; I2 = 46%). Separate comparison of uni- and multimodal prehabilitation showed no difference for either intervention.

CONCLUSION

Prehabilitation reduces ICU LOS compared with SOC in elective surgery patients but has no effect on overall complication rates or total LOS, regardless of modality. Prehabilitation programs need standardization and specific targeting of those patients most likely to benefit.

Comparative study using propensity score matching analysis in patients undergoing surgery for colorectal cancer with or without multimodal prehabilitation

INTRODUCTION

The complication rate after major abdominal surgery is from 35 to 50%. The multimodal prehabilitation covers all the pre-operative problems to guarantee a faster recovery and reduce the rate of morbidity and mortality after a colorectal procedure.

METHODS

Observational study, in patients with CRC who underwent surgical treatment between November 2020 and September 2022. The data of the patients were placed in 2 groups: prehabilitation group (PPH) and no prehabilitation group (NPPH). Demographic data, type of cancer, operative data, and postoperative data were collected. Characteristics between the groups were compared after a propensity score matching (PSM) analysis for the detection of differences.

RESULTS

After the PSM analysis, 46 patients were in PPH, and 63 patients were in NPPH. There was no significant difference in postoperative complications (p = 0.192). The median of comprehensive complication index (CCI) was 0 (p = 0.552). Patients in the NPPH had more hospital readmissions (p = 0.273) and more emergency room visits (p = 0.092). Multivariate log binomial regression adjusted for complications showed that pre-habilitation reduces the risk of a pos-operative complication (OR: 0.659, 95%CI, 0.434-1.00, p = 0.019).

CONCLUSIONS

The postoperative complication rate and LOS were similar between patients who receive operative multimodal prehabilitation for CRC surgery and those who did not. Prehabilitation was associated with reduced risk of postoperative complication after multivariate log binomial regression adjusted for complications. Patients who underwent prehabilitation had a slightly lower tendency for postoperative ER visits and hospital readmissions.

Multimodal prehabilitation to improve the clinical outcomes of frail elderly patients with gastric cancer: a study protocol for a multicentre randomised controlled trial (GISSG+2201)

INTRODUCTION

Gastric cancer (GC) diagnosed in the elderly population has become a serious public health problem worldwide. Given the combined effects of frailty and the consequences of cancer treatment, older individuals with GC are more likely than young patients to suffer from postoperative complications and poor clinical outcomes. Nutrition, functional capacity and psychological state-based multimodal prehabilitation, which is dominated by Enhanced Recovery After Surgery (ERAS) pathway management, has been shown to reduce postoperative complications, promote functional recovery and decrease hospitalisation time in certain malignancies. However, no previous studies have investigated the clinical application of multimodal prehabilitation in frail older patients with GC.

METHODS AND ANALYSIS

The study is a prospective, multicentre randomised controlled trial in which a total of 368 participants who meet the inclusion criteria will be randomised into either a prehabilitation group or an ERAS group. The prehabilitation group will receive multimodal prehabilitation combined with ERAS at least 2 weeks before the gastrectomy is performed, including physical and respiratory training, nutritional support, and therapy and psychosocial treatment. The ERAS group patients will be treated according to the ERAS pathway. All interventions will be supervised by family members. The primary outcome measures are the incidence and severity of postoperative complications. Secondary outcomes include survival, functional capacity and other short-term postoperative outcomes. Overall, the multimodal prehabilitation protocol may improve functional capacity, reduce the surgical stress response and concomitant systemic inflammation, and potentially modulate the tumour microenvironment to improve short-term and long-term clinical outcomes and patients' quality of life.

ETHICS AND DISSEMINATION

All procedures and participating centres of this study were approved by their respective ethics committees (QYFYKYLL 916111920). The final study results will be published separately in peer-reviewed journals.

Is preoperative physical function testing predictive of length of stay in patients with colorectal cancer? A retrospective study

Surgery is the primary treatment for colorectal cancer. A prolonged Length of Stay (pLOS) can increase risk of complications and physical inactivity, leading to a decline in physical function. While promising results were seen from preoperative exercise training and post-operative functional recovery, the predictive potential of preoperative physical function has not yet been investigated. The objective of this study is to determine if preoperative physical function can predict pLOS in patients with colorectal cancer. A total of 459 patients from 7 cohorts were analyzed. Logistic regression was used to determine risk of pLOS (>3 days), and ROC curve was plotted to establish sensitivity/specificity. Selected variables included age, sex, BMI, comorbidity, ASA status, tumor site, surgical approach, handgrip strength, Timed-Up and Go, 30-s Sit-to-Stand, 30-s Arm Curl Test, 6-Minute-Walking Test (6MWT), CHAMPS Physical Activity Questionnaire for Older Adult and the 36-Item Short Form Survey. The results showed that patients with rectal tumor are 2.7x more at risk to be in the pLOS group compared to those with colon tumor (O.R. 2.7; C.I. 1.3-5.7, p=0.01). For every increment of 20 m in 6MWT, there is a decreased risk of 9% of being in pLOS group (C.I. 1.03-1.17, p=0.00). A cut-off of 431 m can predict 70% of patients in pLOS group (AUC 0.71 C.I 0.63-0.78, p=0.00). Tumor site (rectal) and 6MWT were significant predictors of pLOS. Using the 6MWT as a screening tool for pLOS with cut-off of 431 m should be implemented in the preoperative surgical pathway.

Concepts for exercise therapy in prehabilitation for elderly people with frailty or pre-frailty prior to elective surgery. A scoping review

BACKGROUND

Frailty is a state of reduced functional capacities in older people that can be reversed through multimodal therapy concepts. The effect of preoperative prehabilitation on frailty has been examined, but the heterogeneity of exercise regimens has prevented conclusive evidence. This scoping review analyses prehabilitation interventions, particularly exercise methods, published in trials for prefrail and frail elderly patients.

METHOD

We identified studies evaluating prehabilitation for frail elderly using the framework of Arksey and O'Malley. Five scientific databases were searched until March 2022. Articles were screened by two independent reviewers. Data extraction included, but was not limited to, study design, intervention protocol of the prehabilitation including exercise therapy and additional interventions, and safety of the reported exercise concepts.

RESULTS

Nineteen studies were included, offering an insight into the utilized prehabilitation concepts for exercise. All study interventions were based around exercise programs, potentially with complementary interventions. Twelve studies based their exercise programs on a combination of endurance and strength training. Breathing exercises were prescribed in five studies, flexibility routines in five, and one study included balance training. Further interventions included nutritional counselling/supplementation in nine studies, smoking/alcohol cessation in five, in addition to two physiological and three medical/pharmaceutical interventions.

DISCUSSION

Prehabilitation for the frail elderly is safe and feasible. The general concept of prehabiliation for frail patients is promising. An exercise program should focus on improving the patient's endurance and strength, considering the positive effects that can be provided by breathing exercises and other additional interventions, such as nutritional support or lifestyle counselling.

Postponing surgery to optimise patients with acute right-sided obstructing colon cancer - A pilot study

BACKGROUND

Right-sided obstructing colon cancer is most often treated with acute resection. Recent studies on right-sided obstructing colon cancer report higher mortality and morbidity rates than those in patients without obstruction. The aim of this study is to retrospectively analyse whether it is possible to optimise the health condition of patients with acute right-sided obstructing colon cancer, prior to surgery, and whether this improves postoperative outcomes.

METHOD

All consecutive patients with high suspicion of, or histologically proven, right-sided obstructing colon cancer, treated with curative intent between March 2013 and December 2019, were analysed retrospectively. Patients were divided into two groups: optimised group and non-optimised group. Pre-operative optimisation included additional nutrition, physiotherapy, and, if needed, bowel decompression.

RESULTS

In total, 54 patients were analysed in this study. Twenty-four patients received optimisation before elective surgery, and thirty patients received emergency surgery, without optimisation. Scheduled surgery was performed after a median of eight days (IQR 7-12). Postoperative complications were found in twelve (50%) patients in the optimised group, compared to twenty-three (77%) patients in the non-optimised group (p = 0.051). Major complications were diagnosed in three (13%) patients with optimisation, compared to ten (33%) patients without optimisation (p = 0.111). Postoperative in-hospital stay, 30-day mortality, as well as primary anastomosis were comparable in both groups.

CONCLUSION

This pilot study suggests that pre-operative optimisation of patients with obstructing right sided colonic cancer may be feasible and safe but is associated with longer in-patient stay.

Reporting quality of randomized controlled trials in prehabilitation: a scoping review

BACKGROUND

Inadequate study reporting precludes interpretation of findings, pooling of results in meta-analyses, and delays knowledge translation. While prehabilitation interventions aim to enhance candidacy for surgery, to our knowledge, a review of the quality of reporting in prehabilitation has yet to be conducted. Our objective was to determine the extent to which randomized controlled trials (RCTs) of prehabilitation are reported according to methodological and intervention reporting checklists.

METHODS

Eligibility criteria: RCTs of unimodal or multimodal prehabilitation interventions.

SOURCES OF EVIDENCE

search was conducted in March 2022 using MEDLINE, Embase, PsychINFO, Web of Science, CINAHL, and Cochrane.

CHARTING METHODS

identified studies were compared to CONSORT, CERT & Modified CERT, TIDieR, PRESENT, and CONSORT-SPI. An agreement ratio (AR) was defined to evaluate if applicable guideline items were correctly reported. Data were analyzed as frequency (n, %) and mean with standard deviation (SD).

RESULTS

We identified 935 unique articles and included 70 trials published from 1994 to 2022. Most prehabilitation programs comprised exercise-only interventions (n = 40, 57%) and were applied before oncologic surgery (n = 32, 46%). The overall mean AR was 57% (SD: 20.9%). The specific mean ARs were as follows: CONSORT: 71% (SD: 16.3%); TIDieR: 62% (SD:17.7%); CERT: 54% (SD: 16.6%); Modified-CERT: 40% (SD:17.8%); PRESENT: 78% (SD: 8.9); and CONSORT-SPI: 47% (SD: 22.1).

CONCLUSION

Altogether, existing prehabilitation trials report approximately half of the checklist items recommended by methodological and intervention reporting guidelines. Reporting practices may improve with the development of a reporting checklist specific to prehabilitation interventions.

Prehabilitation in the lung cancer pathway: a scoping review

BACKGROUND

Lung cancer is the third most common type of cancer in the UK. Treatment outcomes are poor and UK deaths from lung cancer are higher than any other cancer. Prehabilitation has shown to be an important means of preparing patients both physically and psychologically for cancer treatment. However, little is understood about the context and mechanisms of prehabilitation that can impact physiological and psychological wellbeing. Our aim was to review and summarise primary research on prehabilitation in the lung cancer pathway using a realist approach.

METHODS

A scoping review of empirical primary research was conducted. Five online medical databases from 2016 - February 2023 were searched. All articles reporting on prehabilitation in lung cancer were included in the review. For this review, prehabilitation was defined as either a uni-modal or multi-modal intervention including exercise, nutrition and/or psychosocial support within a home, community or hospital based setting. A realist framework of context, mechanism and outcome was used to assist with the interpretation of findings.

RESULTS

In total, 31 studies were included in the review, of which, three were published study protocols. Over 95% of studies featured an exercise component as part of a prehabilitation programme. Twenty-six of the studies had a surgical focus. Only two studies reported using theory to underpin the design of this complex intervention. There was large heterogeneity across all studies as well as a lack of clinical trials to provide definitive evidence on the programme design, setting, type of intervention, patient criteria, delivery, duration and outcome measures used.

CONCLUSION

A standardised prehabilitation programme for lung cancer patients does not yet exist. Future lung cancer prehabilitation programmes should take into account patient led values, needs, goals, support structures and beliefs, as these factors can affect the delivery and engagement of interventions. Future research should consider using a conceptual framework to conceptualise the living with and beyond cancer experience to help shape and inform personalised prehabilitation services.

Racial disparities in time to laparoscopic cholecystectomy for acute cholecystitis

BACKGROUND

Disparities in healthcare exist, yet few data are available on racial differences in time from admission to surgery. This study aimed to compare time from admission to laparoscopic cholecystectomy for acute cholecystitis between non-Hispanic Black and non-Hispanic White patients.

METHODS

Patients who underwent laparoscopic cholecystectomy for acute cholecystitis from 2010 to 2020 were identified using NSQIP. Time to surgery and additional preoperative, operative, and postoperative variables were analyzed.

RESULTS

In the univariate analysis, 19.4% of Black patients experienced a time to surgery >1 day compared with 13.4% of White patients (p < 0.0001). In the multivariable analysis, controlling for potential confounding factors, Black patients were found to be more likely than White patients to experience a time to surgery >1 day (OR 1.23, 95% CI 1.17-1.30, p < 0.0001).

CONCLUSIONS

Further investigation is indicated to better define the nature and significance of gender, race, and other biases in surgical care. Surgeons should be aware that biases may adversely impact patient care and should strive to identify and proactively address them to promote health equity in surgery.
