The Role and Effect of Multimodal Prehabilitation Before Major Abdominal Surgery: A Systemic Review and Meta-Analysis

Effects of Mobilization Within 24 Hours Based on the ICU Mobility Scale in Cancer Patients: A Randomized Controlled Clinical Trial "Mobilization Based on the ICU Mobility Scale"

BACKGROUND AND OBJECTIVE

Abdominal cancer surgery leads to loss of functional capacity. The objective was to evaluate the effects of mobilization within 24 h applied to patients with abdominal neoplasms undergoing major surgery.

METHODS

A randomized controlled clinical trial was carried out in the Intensive Care Unit. The intervention group performed mobility activities guided by the ICU mobility scale (IMS) in the first 24 h after surgery and the control group performed conventional physiotherapy. Dynamometry was evaluated in the preoperative, 1st POD and postoperative period, as well as the Timed up and go test (TUG).

RESULTS

Patients in the intervention group had greater initial mobility (IMS Scale intervention group: 6.67 ± 0.69; IMS Scale control group: 2.23 ± 0.52; p = 0.001). There was greater level of mobility until discharge from the ICU in patients in the intervention group compared to the control group (IMS at discharge from the ICU in the intervention group: 8.53 ± 0.33; IMS at discharge from the ICU in the control group: 3 ± 0.64). Both groups showed worsening in the TUG test, but it was significant only in the control group.

CONCLUSION

Early mobilization in patients with abdominal neoplasms undergoing major surgery proved to be effective in maintaining mobility and functional markers.

Prehabilitation Strategies: Enhancing Surgical Resilience with a Focus on Nutritional Optimization and Multimodal Interventions

Surgery imposes significant physiological and psychological stress, often leading to complications, delayed recovery, and prolonged hospital stays. Prehabilitation, a proactive strategy to optimize patients' resilience before surgery, has emerged as a transformative approach in perioperative care. Nutritional prehabilitation specifically addresses metabolic dysregulation, muscle loss, and immune suppression caused by surgical stress. This review highlights the critical role of nutritional prehabilitation within a multimodal framework, integrating exercise, psychological support, and emerging technologies. Although some evidence supports the effectiveness of prehabilitation in enhancing functional outcomes and improvements in rates of complications and mortality, its implementation faces challenges such as resources, lack of standardized protocols, and variability across healthcare settings, highlighting the need for greater standardization. Physical training as part of prehabilitation also improves mood, fosters patient engagement, and instills a sense of control over the disease process. These psychosocial benefits, alongside enhanced patient-reported outcomes and qualitative measures, reflect the holistic value of prehabilitation. Emerging technologies, such as wearable devices and telemedicine, offer scalable and personalized solutions for delivering prehabilitation, particularly in resource-limited settings. Future research should prioritize refining protocols, exploring long-term outcomes, and addressing the unique needs of high-risk populations. By emphasizing a proactive approach to perioperative care, this review aims to highlight the potential of nutritional prehabilitation as a foundational component of multimodal strategies designed to optimize surgical resilience, empower patients, and transform surgical recovery into a proactive and patient-centered journey.

Preoperative Optimization for Elective Surgery in Crohn's Disease: A Narrative Review

Crohn's disease is a chronic inflammatory bowel disease and, despite an increase in the available drug treatments, many patients will still require surgery at some point in their disease course. Stricturing and penetrating phenotypes of Crohn's disease are less likely to respond to our current medical treatment and, therefore, surgical intervention may be required. This is most commonly elective, planned surgery, thereby affording the opportunity to optimize medications, nutritional and inflammatory status, and steroid use. Poor nutritional status and previous surgery increase the risk of postoperative complications. Preoperative optimization has three main goals: reduction of postoperative complications; reduction of reoperation rates; and reduction of postoperative recurrence rates. A literature search was completed using PubMed, Embase, and Ovid using the search term "preoperative optimization in Crohn's disease", and it included both adult and pediatric studies, excluding those for perianal Crohn's disease. In this narrative review, we examine the role of nutritional intervention, medical optimization pre and postoperatively, and the role of personalized prehabilitation in the reduction of postoperative complications. We demonstrate that these may all yield better postoperative outcomes for patients with Crohn's disease undergoing elective surgery, although the evidence is somewhat limited and there is a requirement for more prospective randomized controlled trials to implement their role into standard practice or guidelines.

Nutritional Prehabilitation: Trends in Supplementation Based on Sustainable Dairy Protein Sources

PURPOSE OF REVIEW

Prehabilitation is an emerging clinical practice that aims to improve the surgical recovery and quality of life of patients undergoing intensive treatments. This review intends to describe the state of the art in prehabilitation, highlighting the role of nutritional strategies and the current trends in supplements.

RECENT FINDINGS

Up-to-date studies have shown the importance of optimizing the nutritional status of patients to cope with the physical and metabolic demands of surgery and intensive treatments. In the context of nutritional prehabilitation, oral nutritional supplementation has emerged as a preferred strategy. The effectiveness of prehabilitation has been demonstrated in various clinical contexts. However, the lack of standardized protocols makes it hard to compare the outcomes. Despite the variability in this type of nutritional intervention found in reports, it has been shown that the most common oral nutritional supplements (ONS) contain dairy proteins. The use of whey proteins represents a promising approach from both a nutritional and a sustainability perspective.

Pre-operative impact of multimodal prehabilitation in gynecologic oncology patients

OBJECTIVE

Multimodal prehabilitation is a multi-disciplinary program that includes exercise, nutrition, and psychological intervention before surgery to improve pre-operative functional capacity. This study aims to assess the impact of a prehabilitation program on the pre-operative functional status of gynecologic oncology patients.

METHODS

This single-center, prospective observational study included all consecutive patients diagnosed with gynecologic cancer who were scheduled for surgery and enrolled in a structured prehabilitation program from January 2018 to May 2024. Only patients with both baseline and pre-operative evaluations were included. Functional status data were compared before (baseline) and after (pre-operative) the prehabilitation intervention. The primary outcome measured was functional capacity, as determined by the 6-minute walk test (6MWT). Secondary outcomes included hand grip strength, the Malnutrition Universal Screening Tool (MUST) score, and the Hospital Anxiety and Depression Scale score. The type of training and adherence were also evaluated.

RESULTS

A total of 77 patients underwent both baseline and pre-operative evaluation at the prehabilitation unit. The median duration of the program was 25.2 days (range; 9-63). Significant pre-operative improvements were observed in 6MWT (baseline: 435.7 m, standard deviation [SD] = 115.9 vs pre-operative: 455.7 m, SD = 118.9, p < .001), hand grip strength (baseline: 19.0 kg, SD = 5.5 vs pre-operative: 20.4 kg, SD = 5.9, p = .012), MUST score (baseline MUST ≥2 in 14.3% patients vs pre-operative 3.9%, p = .03), and Hospital Anxiety and Depression Scale score (baseline anxiety score: 7.4, SD = 4.3 vs pre-operative: 6.3, SD = 3.6, p < .001; and baseline depression score: 5.5, SD = 4.2 vs pre-operative: 4.3, SD = 3.6, p < .001). Among the different training programs, patients participating in supervised CrossFit training showed greater improvement in the 6MWT (33.4 m), compared to the hospital-supervised group (27.1 m), and the non-supervised home training group (14.0 m).

CONCLUSIONS

A structured multimodal prehabilitation program improves pre-operative functional capacity in gynecologic oncology patients, with the greatest improvements seen in those who participated in supervised high-intensity training, such as CrossFit.

Physical Prehabilitation for Older Patients with Cancer before Complex Medical-Surgical Interventions: An Umbrella Review

Prehabilitation has become a field of increasing interest over recent decades. However, few studies specifically investigated prehabilitation for older patients with cancer. The objective of this umbrella review was to summarize evidence on prehabilitation programs to identify the physical interventions that may be applied with benefit to older cancer patients who will undergo complex medical-surgical procedures. The protocol was registered in Prospero. Major databases, namely PubMed, Embase, CINAHL, Cochrane, Web of Science and Prospero, were searched until summer 2020 and a second search was performed until November 2023. All systematic reviews and meta-analyses were included, dealing with the major topic of prehabilitation for older patients with cancer diagnosis. Among 1425 records (633 until 2020, 792 until November 2023), 14 reviews were selected for inclusion. According to the AMSTAR-2 checklist, the median quality score was 11 (range: 5-12). Total duration of prehabilitation ranged from 1 to 5 weeks, session duration from 20 to 50 minutes, session frequency from 3 to 6 per week. Reported program modes were aerobic and resistance exercises. Concerning the outcome measures, the functional as well as the respiratory status was significantly affected. Quality of life did not benefit significantly, but showed a positive trend. The length of hospital stay was not significantly improved in the majority of the studies. In contrast, most systematic reviews reported significantly lower numbers of total postoperative complications. Functional recovery was enhanced in half of the found reviews. Prehabilitation is a growing field, notably also in reviews focussing on oncological care for elderly patients included in this umbrella review. Aerobic and resistance exercises are the core of the majority of the programs evaluated but their characteristics (total duration, frequency) are partly heterogeneous. Prehabilitation for older patients may also include other modalities of geriatric interventions like nutritional or psychological optimization.

Exploring the acceptability of and adherence to prehabilitation and rehabilitation in patients undergoing major abdominal surgery: A systematic review and meta-analysis

BACKGROUND AND AIMS

Prehabilitation combines exercise, nutritional, and psychological interventions administered before surgery to improve patient outcomes. This comprehensive review and meta-analysis examined the feasibility, adherence, and effectiveness of prehabilitation in frail, high-risk individuals undergoing major abdominal surgery.

METHODS

We searched the Cochrane Central Register of Controlled Trials, Web of Science, MEDLINE, Embase, and Cumulative Index to Nursing & Allied Health Literature (CINAHL) databases to identify relevant studies evaluating prehabilitation programs published between 2010 and 2023, either as observational studies or randomized clinical trials (RCTs).

RESULTS

The 23 articles (13 RCTs and 10 observational studies) included 1849 older male and female patients aged 68.7 ± 7.2 years. Nineteen of the included studies reported on adherence to prehabilitation programmes, which was generally good (>75%) over different models, settings, and durations. Factors such as patients' desire for expedited surgery, self-assessment of fitness, personal and professional obligations, health issues, holidays, and advancement of surgery dates negatively affected adherence to prehabilitation programmes. When compared with rehabilitation or standard pre- and post-surgical care, prehabilitation was associated with a 25%, albeit not statistically significant reduction in postoperative complications, according to data from 14 studies reporting on postoperative complications (OR 0.75, 95% CI 0.48 to 1.17, P = 0.43; I2 = 65%). Prehabilitation has been found to improve the 6-min walk test significantly by 29.4 m (MD +29.4 m, 95% CI 5.6 to 53.3, P = 0.02; I2 = 39%), compared with rehabilitation or standard pre- and post-surgical care.

CONCLUSION

Prehabilitation was acceptable to patients, with good adherence, and improved physical function.

Prehabilitation to Enhance Vascular Surgery Outcomes: A Narrative Review

Prehabilitation, an emerging strategy, prepares patients for elective surgery by encouraging healthy behaviors, including physical exercise and healthy nutrition, while providing psychological support, to improve postoperative outcomes and foster healthier lifestyles. Despite growing interest, there is little research on prehabilitation. Specifically, studies involving prehabilitation in vascular surgery are heterogeneous with small sample sizes. This review aimed to investigate the reported positive impact of prehabilitation on vascular surgery patients, discuss prehabilitation models, highlight prehabilitation program-associated challenges, and suggest appropriate interventions. Prehabilitation improves physical fitness, reduces postoperative complications, and enhances overall recovery. Multimodal prehabilitation programs can positively impact vascular surgery patients, with benefits including improved cardiovascular fitness, reduced postoperative complications, shorter postoperative hospital stays, enhanced overall recovery, and improved quality of life. The currently reported prehabilitation programs are heterogeneous, with limitations regarding patient adherence and lack of long-term outcomes, posing challenges to their widespread adoption. Overall, prehabilitation shows promise for improving vascular surgery outcomes and fostering long-term healthy behaviors. The systematic implementation of prehabilitation in vascular surgery care pathways, overcoming reported limitations, and integrating multimodal prehabilitation into routine preoperative care hold potential benefits. This review underscores the need for high-quality research to establish best practices in prehabilitation and integrate them into the standard of care for vascular surgery patients.

Perioperative management of sarcopenia in patients undergoing major surgeries in Singapore: a modified Delphi consensus

BACKGROUND

Ageing population is a worldwide phenomenon with correspondingly higher proportion of older patients being treated in the hospital setting. Sarcopenia, which increases with age, has serious negative implications on health, hospitalisation, and overall postoperative recovery. There is no mutual consensus on perioperative management of sarcopenia in surgical patients in Singapore. The purpose of this study is to create greater clarity pertaining to the recognition of sarcopenia, the application of assessment criteria of sarcopenia and perioperative management of surgical patients in Singapore.

METHODS

A modified Delphi consensus consisting of a panel of experts from Singapore forming a multidisciplinary team, including surgeons, geriatricians, anesthesiologists, physiotherapists, and dieticians. Eight recommendations were proposed by the steering committee. Literature search from MEDLINE, Embase, and Scopus for articles up till June 2023 were performed to support recommendation statements. The expert panel voted on agreement to recommendation statements and graded the level of evidence supporting each statement through surveys to achieve consensus, set at 85% a priori.

RESULTS

The panellists underwent two rounds of anonymized, independent voting before reaching consensus for all eight statements. After the first round, seven statements reached consensus, including the corresponding grading for level of evidence. The statement which did not achieve consensus was revised with supporting literature and after the second round of survey, all eight statements and level of evidence reached consensus, completing the Delphi process. These eight statements covered themes to (1) encourage the identification of sarcopenia, (2) guide preoperative, and (3) postoperative management of sarcopenia.

CONCLUSION

With the varying approaches in perioperative management, poor understanding of and identification of sarcopenia can result in suboptimal management of sarcopenia in surgical patients. Given the abundance of evidence linking beneficial impact on recovery and postoperative complications with prudent management of sarcopenia, it is imperative and urgent to achieve awareness and consensus.

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.

Multimodal Prehabilitation for Patients with Crohn's Disease Scheduled for Major Surgery: A Narrative Review

Approximately 15-50% of patients with Crohn's disease (CD) will require surgery within ten years following the diagnosis. The management of modifiable risk factors before surgery is essential to reduce postoperative complications and to promote a better postoperative recovery. Preoperative malnutrition reduced functional capacity, sarcopenia, immunosuppressive medications, anemia, and psychological distress are frequently present in CD patients. Multimodal prehabilitation consists of nutritional, functional, medical, and psychological interventions implemented before surgery, aiming at optimizing preoperative status and improve postoperative recovery. Currently, studies evaluating the effect of multimodal prehabilitation on postoperative outcomes specifically in CD are lacking. Some studies have investigated the effect of a single prehabilitation intervention, of which nutritional optimization is the most investigated. The aim of this narrative review is to present the physiologic rationale supporting multimodal surgical prehabilitation in CD patients waiting for surgery, and to describe its main components to facilitate their adoption in the preoperative standard of care.

Malnutrition in cancer patients: Causes, consequences and treatment options

Cancer patients are at a high risk of malnutrition and disease-associated catabolic derangements. It is important to differentiate between 'simple' - voluntary or involuntary - caloric restriction with protein-sparing ketogenic metabolic adaptation and cachexia, characterized by the combination of weight loss and dysmetabolism, most prominently systemic inflammation. While both conditions result in the sacrifice of fat and protein stores and thus impact on treatment tolerance, complication rates and survival, the presence of metabolic derangements is especially dangerous by straining multiple organ functions. To avoid underdiagnosing and undertreating malnutrition, all cancer patients should be routinely screened for nutritional risk. At-risk patients require comprehensive assessment for contributing and treatable causes and, if available, multi-professional efforts to improve food intake, support anabolism, alleviate distress and antagonize pro-inflammatory processes. In curative settings, anabolic support should accompany or even precede anticancer treatments. Prehabilitation before major surgery, has been studied extensively, including muscle training as well as nutritional and/or psychological support. Recent meta-analyses report a consistent benefit on functional capacity and possible improvement in postoperative complications and length of hospital stay. In palliative settings, prevailing catabolic derangements require careful assessment of the individual constellation of disturbed functions and an empathic evaluation of benefits and risks of nutritional interventions. This is of special relevance in patients with an expected survival of less than a few months. Due to the complex interactions of mechanical, metabolic and psychological factors, multi-professional teams should be involved.

Multimodal prehabilitation program in patients with resectable perihilar cholangiocarcinoma: keypoints for an implementation protocol and literature review

BACKGROUND

Postoperative complications after perihilar cholangiocarcinoma surgical procedure are still very high. The implementation of a multimodal prehabilitation program could improve these outcomes. Based on our experience and that of the literature in hepatobiliary and pancreatic surgery, we propose a protocol to promote its implementation.

METHODS

First, we performed a retrospective analysis of the implementation feasibility of a multimodal prehabilitation program in patients' candidates for elective perihilar cholangiocarcinoma surgery in our center. Second, we conducted a literature search of publications in PubMed until December 2022. Relevant data about hepato-pancreato-biliary surgery and prehabilitation programs in features and postoperative outcomes was analyzed.

RESULTS

Since October 2020, 11 patients were evaluated for prehabilitation in our hospital. Two of them could not be resected intraoperatively due to disease extension. The median hospital stay was 10 days (iqr, 7-11). There were no major complications and 1 patient died. Of a total of 17 articles related to prehabilitation in hepato-biliary-pancreatic surgery, no reports focusing exclusively on perihilar cholangiocarcinoma were found. Six of the studies had nutritional therapies in addition to physical interventions, and 12 studies used home-based exercise therapy.

CONCLUSIONS

Based on our experience and the data obtained from other studies, a prehabilitation program could be useful to improve perioperative physical and mental fitness in patients' candidates for elective perihilar cholangiocarcinoma surgery. However, more well-designed studies are needed to allow us to obtain more evidence.

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.

Time to surgery is not an oncological risk factor in patients with cholangiocarcinoma undergoing curative-intent liver surgery

Surgical resection is the only option to achieve long-term survival in cholangiocellular carcinoma (CCA). Due to limitations of health care systems and unforeseeable events, e.g., the COVID pandemic, the time from diagnosis to surgery (time-to-surgery (TTS)) has gained great interest in malignancies. Thus, we investigated whether TTS is associated with the oncological outcome in patients who underwent surgery for CCA. A cohort of 276 patients undergoing curative-intent surgery for intrahepatic and perihilar CCA excluding individuals with neoadjuvant therapy and perioperative mortality between 2010 and 2021 were eligible for analysis. Patients were grouped according to TTS (≤ 30; 31-60; 61-90; > 90 days) and compared by Kruskal-Wallis-analysis. Survival was compared using Kaplan-Meier analysis and characteristics associated with cancer-specific survival (CSS), recurrence-free survival (RFS) and overall survival (OS) using Cox regressions. The median CSS was 39 months (3-year-CSS = 52%, 5-year-CSS = 42%) and the median RFS 20 months (3-year-CSS = 38%, 5-year-CSS = 33%). In univariable Cox regressions, TTS was not associated with CSS (p = 0.971) or RFS (p = 0.855), respectively. A grouped analysis with respect to TTS (≤ 30 days, n = 106; 31-60 days, n = 134; 61-90 days, n = 44; > 90 days, n = 29) displayed a median CSS of 38, 33, 51 and 41 months and median RFS of 17, 22, 28 and 20 months (p = 0.971 log rank; p = 0.520 log rank). No statistical difference regarding oncological risk factors were observed between the groups. This study is the first comprehensive analysis of TTS in CCA patients. Within a representative European cohort, TTS was not associated with earlier tumor recurrence or reduced CCS.

Community-based prehabilitation in older patients and high-risk patients undergoing colorectal cancer surgery

INTRODUCTION

Prehabilitation before colorectal cancer (CRC) surgery is promising to prevent complications and to enhance recovery, especially in patients aged 70 or older or in patients with an American Society of Anaesthesiologist (ASA) physical classification score 3-4, for whom surgery is associated with higher postoperative complications and long-lasting adverse effects on functional performance.

MATERIALS AND METHODS

A cohort study was conducted in a large teaching hospital in Alkmaar, the Netherlands. Fifty CRC patients (≥70 years or ASA 3-4) underwent multimodal prehabilitation between September 2020 and July 2021. The reference group comprised 50 patients (≥70 years or ASA 3-4) from a historical cohort receiving CRC surgery without prehabilitation (March 2020-August 2020). The primary outcome was 90-day postoperative complication rate. Secondary outcomes were length of stay, 90-day readmission and mortality rates and functional outcome in the prehabilitation group.

RESULTS

One patient in the prehabilitation group decided not to undergo surgery. Of the remaining 49 patients, 48 (98.0 %) received prehabilitation for at least 3 weeks. Of these patients, 32.7 % developed postoperative complications, compared to 58 % in the reference group (p = 0.015), and none were readmitted, in contrast to 6 reference group patients (12.0 %, p = 0.012). Length of stay and mortality did not differ significantly. Six weeks postoperatively, all functional outcomes in the prehabilitation group were significantly higher than at baseline.

CONCLUSIONS

Prehabilitation reduced postoperative complications and improved short-term functional outcomes in older and high-risk patients receiving CRC surgery. Further research should investigate the maintenance of long-term enhanced lifestyle and the effects of tailor-made programs.

A global analysis of nutrition support practices in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal malignancy

BACKGROUND

Perioperative nutritional care has been identified as an important factor in the management of patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Nevertheless, there is no published consensus on best practice for nutritional management specific to this patient group. The purpose of this study was to identify the current nutrition care practices among international centres performing CRS and HIPEC for patients with peritoneal malignancy.

METHODS

An online survey was developed and sent to experienced CRS and HIPEC centres. The survey questions covered clinician and institution demographics, formal nutrition care pathways, pre-operative nutrition care, post-operative nutrition support and post-discharge nutritional follow-up.

RESULTS

Eighty-two centres were contacted, and 42 responses were received. Respondents were from 20 different countries and were mostly dietitians (71%). Nutrition assessments were frequently completed (52% pre-operatively and 86% post-operatively) and most centres used a validated nutrition screening or assessment tool (79%). Perioperative nutrition support with respect to the use of enteral nutrition, parenteral nutrition and enhanced recovery after surgery varied widely between centres. The use of routine parenteral and enteral nutrition was significantly higher in Europe compared with other locations (p = 0.028).

CONCLUSIONS

Nutrition care is pivotal and has been positively integrated into the complex management of patients undergoing CRS and HIPEC globally, however variation in practice is evident. The findings highlight a unique opportunity to collaboratively investigate the role nutrition plays in determining outcomes and to identify the most appropriate nutrition support methods to achieve improved clinical outcomes for these high-risk patients.

[Current Status of and Barriers to the Implementation of Enhanced Recovery After Surgery in 77 Tertiary Hospitals]

Objective

To investigate the status of and obstacles to the implementation of enhanced recovery after surgery (ERAS) in tertiary-care general hospitals in China.

Methods

Questionnaire on the Current Status of and Barriers to the Implementation of ERAS in Tertiary-Care Hospitals, a self-developed questionnaire, was used to conduct a survey of 77 tertiary hospitals from 21 provinces across China between May 2022 and June 2022. The participating hospitals were selected by convenience sampling. The questionnaire on the current implementation status of ERAS was mainly focused on the departments involved and the ERAS programs implemented, incorporating a total of 25 items of three dimensions, preoperative, intraoperative, and postoperative. The answer to each question consisted of 5 options from "never" to "always", which corresponded to 1 to 5 points on the scoring scale, with the higher scores indicating better implementation of the program concerned. In the questionnaire on barriers to ERAS implementation and recommendations, 10 items of two dimensions, including hospital management, and patient and caregiver, were concerned with the barriers to implementation. The answer to each question consisted of 5 options from "disagree" to "strongly agree", which corresponded to 1 to 5 points on the scoring scale, with the higher scores indicating the greater importance of the barriers.

Results

ERAS programs were implemented in 73 (94.8%) hospitals. The best-implemented items were preoperative education (4.73±0.51), prevention and treatment of deep vein thrombosis (4.55±0.71), and postoperative follow-up (4.40±0.81). The items of poor implementation status were preoperative prehabilitation (2.71±1.40), preoperative oral carbohydrate drinks (3.03±1.49), and early ambulation after surgeries (3.04±1.22). The main obstacles to ERAS implementation included a lack of effective incentive systems, poor motivation among the medical and nursing staffs (3.21±0.93), a lack of disease-specific clinical implementation pathways (3.16±1.06), and a lack of experience in multidisciplinary teamwork (2.98±1.17).

Conclusion

There is a high rate of ERAS implementation in tertiary general hospitals in China, but clinical implementation and dissemination are still confronted with many obstacles.

Training effects of set- and repetition-interval rest time on recumbent-boxing exercise: Could virtual reality improve further?

This study examined the influence of set-interval and repetition-interval rest time of virtual reality (VR) boxing game in supine-lying posture. Fifty healthy middle-aged adults were randomly assigned into VR and non-VR groups to perform six different exercise protocols with varying set-interval and repetition-interval rest times (S0R0, S0R1/3, S0R2/3, S40R0, S40R1/3, and S40R2/3). Analysis on the non-VR group showed significant differences between exercise protocols for average heart rate (p < 0.001), maximum ventilation volume (p < 0.001), respiratory quotient (p < 0.001), oxygen pulse (p < 0.001), and excess post-exercise oxygen consumption (EPOC) (p = 0.003). VR appeared to have no further improvement on physical training effects in middle-aged adults, while the participants reported negative experience that might be associated with the over-exertion. Future study might need to explore game design elements that can accommodate high-exertion exercises.
