Efficacy of Prehabilitation Including Exercise on Postoperative Outcomes Following Abdominal Cancer Surgery: A Systematic Review and Meta-Analysis

THE VALUE OF PREOPERATIVE PROGNOSTIC NUTRITIONAL INDEX IN GASTRIC CANCER AFTER CURATIVE RESECTION

BACKGROUND

Predicting short- and long-term outcomes of oncological therapies is crucial for developing effective treatment strategies. Malnutrition and the host immune status significantly affect outcomes in major surgeries.

AIMS

To assess the value of preoperative prognostic nutritional index (PNI) in predicting outcomes in gastric cancer patients.

METHODS

A retrospective cohort analysis was conducted on patients undergoing curative-intent surgery for gastric adenocarcinoma between 2009 and 2020. PNI was calculated as follows: PNI=(10 x albumin [g/dL])+(0.005 x lymphocytes [nº/mm3]). The optimal cutoff value was determined by the receiver operating characteristic curve (PNI cutoff=52), and patients were grouped into low and high PNI.

RESULTS

Of the 529 patients included, 315 (59.5%) were classified as a low-PNI group (PNI<52) and 214 (40.5%) as a high-PNI group (PNI≥52). Older age (p=0.050), male sex (p=0.003), American Society of Anesthesiologists score (ASA) III/IV (p=0.001), lower hemoglobin level (p<0.001), lower body mass index (p=0.001), higher neutrophil-lymphocyte ratio (p<0.001), D1 lymphadenectomy, advanced pT stage, pN+ and more advanced pTNM stage were related to low-PNI patient. Furthermore, 30-day (1.4 vs. 4.8%; p=0.036) and 90-day (3.3 vs. 10.5%; p=0.002) mortality rates were higher in low-PNI compared to high-PNI group. Disease-free and overall survival were worse in low-PNI patients compared to high-PNI (p<0.001 for both). ASA III/IV score, low-PNI, pT3/T4, and pN+ were independent risk factors for worse survival.

CONCLUSIONS

Preoperative PNI can predict short- and long-term outcomes of patients with gastric cancer after curative gastrectomy. Low PNI is an independent factor related to worse disease-free and overall survival.

A review of patient recruitment in randomised controlled trials of preoperative exercise

BACKGROUND

Randomised controlled trials (RCTs) are considered the gold standard design to determine the effectiveness of an intervention, as the only method of decreasing section bias and minimising random error. However, participant recruitment to randomised controlled trials is a major challenge, with many trials failing to recruit the targeted sample size accordingly to the planned protocol. Thus, the aim of this review is to detail the recruitment challenges of preoperative exercise clinical trials.

METHODS

A comprehensive search was performed on MEDLINE, Embase, The Cochrane Library, CINAHL, AMED and PsycINFO from inception to July 2021. Randomised controlled trials investigating the effectiveness of preoperative exercise on postoperative complication and/or length of hospital stay in adult cancer patients were included. Main outcomes included recruitment rate, retention rate, number of days needed to screen and recruit one patient and trial recruitment duration. Descriptive statistics were used to summarise outcomes of interest.

RESULTS

A total of 27 trials were identified, including 3656 patients screened (N = 21) and 1414 randomised (median recruitment rate (interquartile range) = 53.6% (25.2%-67.6%), N = 21). The sample size of the included trials ranged from 19 to 270 (median = 48.0; interquartile range = 40.0-85.0) and the duration of trial recruitment ranged from 3 to 50 months (median = 19.0 months; interquartile range = 10.5-34.0). Overall, a median of 3.6 days was needed to screen one patient, whereas 13.7 days were needed to randomise one participant. Over the trials duration, the median dropout rate was 7.9%. Variations in recruitment outcomes were observed across trials of different cancer types but were not statistically significant.

CONCLUSION

The recruitment of participants to preoperative exercise randomised controlled trials is challenging, but patient retention appears to be less of a problem. Future trials investigating the effectiveness of a preoperative exercise programme following cancer surgery should consider the time taken to recruit patients. Strategies associated with improved recruitment should be investigated in future studies.

The acceptability of exercise prehabilitation before cancer surgery among patients, family members and health professionals: a mixed methods evaluation

PURPOSE

Exercise prehabilitation aims to increase preoperative fitness, reduce post-operative complications, and improve health-related quality of life. For prehabilitation to work, access to an effective programme which is acceptable to stakeholders is vital. The aim was to explore acceptability of exercise prehabilitation before cancer surgery among key stakeholders specifically patients, family members and healthcare providers.

METHODS

A mixed-methods approach (questionnaire and semi-structured interview) underpinned by the Theoretical Framework of Acceptability was utilised. Composite acceptability score, (summation of acceptability constructs and a single-item overall acceptability construct), and median of each construct was calculated. Correlation analysis between the single-item overall acceptability and each construct was completed. Qualitative data was analysed using deductive and inductive thematic analysis.

RESULTS

244 participants completed the questionnaire and n=31 completed interviews. Composite acceptability was comparable between groups (p=0.466). Four constructs positively correlated with overall acceptability: affective attitude (r=0.453), self-efficacy (r=0.399), ethicality (r=0.298) and intervention coherence (r=0.281). Qualitative data confirmed positive feelings, citing psychological benefits including a sense of control. Participants felt flexible prehabilitation program would be suitable for everyone, identifying barriers and facilitators to reduce burden.

CONCLUSION

Exercise prehabilitation is highly acceptable to key stakeholders. Despite some burden, it is a worthwhile and effective intervention. Stakeholders understand its purpose, are confident in patients' ability to participate, and regard it is an important intervention contributing to patients' psychological and physical wellbeing.

IMPLICATIONS

•Introduction should be comprehensively designed and clearly presented, providing appropriate information and opportunity for questions. •Programmes should be patient-centred, designed to overcome barriers and address patients' specific needs and goals. •Service must be appropriately resourced with a clear referral-pathway.

Nutritional Prehabilitation in Patients Undergoing Cystectomy: A Systematic Review

BACKGROUND/AIM

Nutrition is a key element of the prehabilitation process prior to surgery. The aim of this study was to identify the clinical pathways of nutritional prehabilitation before cystectomy.

METHODS

A systematic literature review was conducted in PubMed, the Cochrane Library, CINAHL, Scopus and the Web of Science databases. Quality and risk of bias assessment was conducted adhering to the JBI framework and evidence was evaluated according to the Oxford Centre for Evidence Based Medicine levels of evidence.

RESULTS

Out of 586 records identified, six studies were included. Among them, only two were randomized controlled trials. Immunonutrition has been shown to improve postoperative bowel function (3.12 vs. 3.74 days; RR 0.82; CI, 0.73-0.93; p = 0.0029) and decrease postoperative complications (-36.7%; p = 0.008) and readmission rates (-15.38%; p = 0.03). Furthermore, oral nutritional supplements combined with nutritional counseling demonstrated an accelerated recovery of bowel function (-1 day; p < 0.01), a reduction in the length of hospital stay (-1.75 days; p = 0.01), an improvement in handgrip strength (+6.8%, p < 0.001), an increase in bone mass (+0.3 kg, p = 0.04), and a better BMI value (+2.3%, p = 0.001).

CONCLUSIONS

Nutritional prehabilitation demonstrates potential in enhancing postoperative outcomes following radical cystectomy. Oral supplements, immunonutrition, and counseling exhibit efficacy in improving postoperative results.

Comparison of various functional assessment tools to identify older patients undergoing aortic aneurysm repair at risk for postoperative complications

BACKGROUND

To estimate whether the benefits of aortic aneurysm repair will outweigh the risks, determining individual risks is essential. This single-center prospective cohort study aimed to compare the association of functional tools with postoperative complications in older patients undergoing aortic aneurysm repair.

METHODS

Ninety-eight patients (≥ 65 years) who underwent aortic aneurysm repair were included. Four functional tools were administered: the Montreal Cognitive Assessment (MoCA); the 4-Meter Walk Test (4-MWT); handgrip strength; and the Groningen Frailty Indicator (GFI). Primary outcome was the association between all tests and 30-day postoperative complications.

RESULTS

After adjusting for confounders, the OR for MoCA was 1.39 (95% CI 0.450;3.157; P=0.723), for 4-MWT 0.63 (95% CI 0.242;1.650; P=0.348), for GFI 1.82 (95% CI 0.783;4.323, P=0.162), and for weak handgrip strength 4.78 (95% CI 1.338;17.096, P=0.016).

CONCLUSION

Weak handgrip strength is significantly associated with the development of postoperative complications after aortic aneurysm repair. This study strengthens the idea that implementing a quick screening tool for risk assessment at the outpatient clinic, such as handgrip strength, identifies patients who may benefit from preoperative enhancement with help from, for example, Comprehensive Geriatric Assessment, eventually leading to better outcomes for this patient group.

Access, acceptance and adherence to cancer prehabilitation: a mixed-methods systematic review

PURPOSE

The purpose of this systematic review is to better understand access to, acceptance of and adherence to cancer prehabilitation.

METHODS

MEDLINE, CINAHL, PsychINFO, Embase, Physiotherapy Evidence Database, ProQuest Medical Library, Cochrane Library, Web of Science and grey literature were systematically searched for quantitative, qualitative and mixed-methods studies published in English between January 2017 and June 2023. Screening, data extraction and critical appraisal were conducted by two reviewers independently using Covidence™ systematic review software. Data were analysed and synthesised thematically to address the question 'What do we know about access, acceptance and adherence to cancer prehabilitation, particularly among socially deprived and minority ethnic groups?' The protocol is published on PROSPERO CRD42023403776 RESULTS: Searches identified 11,715 records, and 56 studies of variable methodological quality were included: 32 quantitative, 15 qualitative and nine mixed-methods. Analysis identified facilitators and barriers at individual and structural levels, and with interpersonal connections important for prehabilitation access, acceptance and adherence. No study reported analysis of facilitators and barriers to prehabilitation specific to people from ethnic minority communities. One study described health literacy as a barrier to access for people from socioeconomically deprived communities.

CONCLUSIONS

There is limited empirical research of barriers and facilitators to inform improvement in equity of access to cancer prehabilitation.

IMPLICATIONS FOR CANCER SURVIVORS

To enhance the inclusivity of cancer prehabilitation, adjustments may be needed to accommodate individual characteristics and attention given to structural factors, such as staff training. Interpersonal connections are proposed as a fundamental ingredient for successful prehabilitation.

Evolving concepts on perioperative nutrition of sarcopenic cancer patients

The recent recognition of the association of sarcopenia with an increased risk of complications after a surgical procedure calls for rethinking the proper approach of the perioperative care in cancer patients. Sarcopenia is broadly considered in literature according to three different definitions: loss of muscle mass, loss of muscle mass plus reduced muscle function and myosteatosis. The aim of this short review on this issue is to define the excess of risk by type of primary and of surgical procedure, depending on the definition of sarcopenia, to speculate on this association (casual versus causal) and to examine the current therapeutical approaches. The analysis of the data shows that sarcopenia, defined as loss of muscle mass plus reduced muscle function, has the higher predictive power for the occurrence of postoperative complications than the two other definitions, and any definition of sarcopenia works better than the usual indexes or scores of surgical risk. Our analysis supports the concept that: a) sarcopenia is frequently associated with inflammation, but inflammation cannot be considered the only or the absolute cause for sarcopenia, b) sarcopenia is not a simple marker of risk but can have a direct role in the increase of risk. Data on perioperative care of sarcopenic cancer patients are scanty but a correct approach cannot rely on nutritional support alone but on a combined approach of optimized nutrition and exercise, hopefully associated with an anti-inflammatory treatment. This strategy should be applied proactively in keeping with the recent recommendations of the American Society of Clinical Oncology for the medical treatment of advanced cancer patients even if a clear demonstration of effectiveness is still lacking.

State of the scientific evidence and recommendations for the management of older patients with gastric cancer

Gastric cancer is one of the most frequent and deadly tumours worldwide. However, the evidence that currently exists for the treatment of older adults is limited and is derived mainly from clinical trials in which older patients are poorly represented. In this article, a group of experts selected from the Oncogeriatrics Section of the Spanish Society of Medical Oncology (SEOM), the Spanish Group for the Treatment of Digestive Tumours (TTD), and the Spanish Multidisciplinary Group on Digestive Cancer (GEMCAD) reviews the existing scientific evidence for older patients (≥65 years old) with gastric cancer and establishes a series of recommendations that allow optimization of management during all phases of the disease. Geriatric assessment (GA) and a multidisciplinary approach should be fundamental parts of the process. In early stages, endoscopic submucosal resection or laparoscopic gastrectomy is recommended depending on the stage. In locally advanced stage, the tolerability of triplet regimens has been established; however, as in the metastatic stage, platinum- and fluoropyrimidine-based regimens with the possibility of lower dose intensity are recommended resulting in similar efficacy. Likewise, the administration of trastuzumab, ramucirumab and immunotherapy for unresectable metastatic or locally advanced disease is safe. Supportive treatment acquires special importance in a population with different life expectancies than at a younger age. It is essential to consider the general state of the patient and the psychosocial dimension.

Prehabilitation for Patients with Cancer Undergoing Radiation Therapy: a Scoping Review

AIMS

Prehabilitation is a process of identifying and assessing factors that could compromise the physical and psychological health of patients undergoing cancer treatment and implementing an intervention to combat such concerns. The use of prehabilitation in cancer surgery has yielded positive outcomes in rectal, lung and abdominal cancers. Prehabilitation strategies have potential to improve the management of patients receiving radiation therapy or chemoradiation. The aim of the present study was to map the evidence of the assessment and evaluation of prehabilitation for radiation therapy patients.

MATERIALS AND METHODS

A database search using EMBASE and PubMed was conducted. The PRISMA guidelines were adhered to. Keywords included prehabilitation, radiation therapy/radiotherapy, chemoradiotherapy/chemoradiation, intervention and exercise. Types of prehabilitation strategy, their purposes and impact, according to cancer site, were analysed.

RESULTS

Prehabilitation is most commonly evaluated in head and neck cancer, whereby unimodal, physical interventions manage dysphagia. Prehabilitation for lung cancer demonstrated its ability to widen treatment options for patients. Physical prehabilitation is administered to combat adverse effects of neoadjuvant chemoradiation therapy in patients with rectal cancer.

CONCLUSION

Prehabilitation is adaptive and tailored to specific patient and site needs; thus it is applied across a wide range of cancer sites. More interventions by which radiation therapy is the definitive treatment modality and larger sample sizes within these studies are warranted to increase prehabilitation utilisation for patients undergoing radiation therapy.

Physical activity for cancer prehabilitation: A scoping review

This scoping review aims to synthesize the current landscape of physical activity in cancer prehabilitation and identify knowledge gaps. We searched MEDLINE, EMBASE, SCOPUS and WEB OF SCIENCE for exercise interventions and observational studies that measured exercise or physical activity before cancer treatment from inception to January 20, 2023. Fifty-one articles from 44 unique studies were reviewed, including 32 intervention and 12 observational studies. Surgery is the only treatment modality that has been investigated. Included studies used heterogeneous exercise interventions and measures for physical activity. Colorectal and other gastrointestinal, lung, and urologic cancers are the most studied cancer types. Exercise intervention in cancer prehabilitation is highly feasible. The evidence for improved fitness, functional, psychosocial, and clinical outcomes is promising yet limited. Although research has increased recently, prehabilitation exercise remains a relatively under-investigated area in oncology. We have provided research directions towards an ideal cancer prehabilitation design in the real-world setting.

Cardio-oncology rehabilitation: are we ready?

Cardio-oncology rehabilitation (CORE) is not only an essential component of cancer rehabilitation but also a pillar of preventive cardio-oncology. Cardio-oncology rehabilitation is a comprehensive model based on a multitargeted approach and its efficacy has been widely documented; when compared with an 'exercise only' programme, comprehensive CORE demonstrates a better outcome. It involves nutritional counselling, psychological support, and cardiovascular (CV) risk assessment, and it is directed to a very demanding population with a heavy burden of CV diseases driven by physical inactivity, cancer therapy-induced metabolic derangements, and cancer therapy-related CV toxicities. Despite its usefulness, CORE is still underused in cancer patients and we are still at the dawning of remote models of rehabilitation (tele-rehabilitation). Not all CORE is created equally: a careful screening procedure to identify patients who will benefit the most from CORE and a multidisciplinary customized approach are mandatory to achieve a better outcome for cancer survivors throughout their cancer journey. The aim of this paper is to provide an updated review of CORE not only for cardiologists dealing with this peculiar population of patients but also for oncologists, primary care providers, patients, and caregivers. This multidisciplinary team should help cancer patients to maintain a healthy and active life before, during, and after cancer treatment, in order to improve quality of life and to fight health inequities.

Feasibility of Introducing a Prehabilitation Program into the Care of Gynecological Oncology Patients-A Single Institution Experience

Prehabilitation is an upcoming strategy to optimize patient's functional capacity, nutritional status, and psychosocial well-being in order to reduce surgical complications and enhance recovery. This study aims to assess the feasibility of implementing a multimodal prehabilitation program into the standard care of gynecological oncology patients at an academic hospital in terms of recruitment, adherence, and safety, which were assessed by the number of patients eligible, recruitment rate, participation rate, and adherence to individual modalities. Data were derived from the F4S PREHAB trial, a single-center stepped-wedge trial implementing a multimodal prehabilitation program among various surgical specialties. All patients undergoing elective surgery as part of treatment for ovarian, uterine, and vulvar cancer at the Radboudumc, an academic hospital in The Netherlands, between May 2022 and September 2023 were considered eligible for the F4S PREHAB trial and, consequently, were included in this cohort study. The multimodal prehabilitation program comprised a physical exercise intervention, nutritional intervention, psychological intervention, and an intoxication cessation program. A total of 152 patients were eligible and approached for participation of which 111 consented to participate, resulting in a recruitment rate of 73%. Participants attended an average of six exercise sessions and adhered to 85% of possible training sessions. Respectively, 93% and 98% of participants adhered to the prescribed daily protein and vitamin suppletion. Ten participants were referred to a psychologist and completed consultations. Out of nine active smokers, two managed to quit smoking. A total of 59% adhered to alcohol cessation advice. No adverse events were reported. This study demonstrates that introducing a multimodal prehabilitation program into the standard care of gynecological oncology patients is feasible in terms of recruitment and adherence, with no serious adverse events.

Impact of a dietitian-led very low calorie diet clinic on perioperative risk for patients with obesity awaiting elective, non-bariatric surgery: A retrospective cohort study

BACKGROUND

Despite a lack of evidence that intentional weight loss reduces the risk of postoperative complications, adults with obesity are commonly asked to lose weight before elective surgery. We hypothesized that patients undertaking dietitian-led preoperative, very low calorie diet treatment could reduce perioperative surgery risks, as per validated risk scoring systems. The purpose of this study was to measure the impact of a dietitian-led preoperative very low calorie diet clinic on the American Society of Anesthesiologists physical status scores and National Surgical Quality Improvement Program Surgical Risk Calculator scores for patients with obesity awaiting non-bariatric elective surgery.

METHODS

This retrospective cohort study included patients referred to the preoperative dietitian-led very low calorie diet clinic before elective surgical procedures over a 2-year-9-month period. The dietitian prescribed individualized, very low calorie diet-based treatment. Primary outcomes were changes in the American Society of Anesthesiologists and Surgical Risk Calculator scores from pretreatment until surgery.

RESULTS

A total of 141 eligible participants (48 ± 13.4 years, 76% women, body mass index 41.7 ± 6.3 kg/m2) demonstrated clinically significant weight loss (mean 7.1 ± 6.1kg, 5.2% body weight, P < .001). Median treatment duration was 13 weeks (interquartile range 6.2-19.2 weeks). Five participants (3.5%) avoided surgery due to weight loss-related improvements in their condition. American Society of Anesthesiologists scores improved for 16% (n = 22/141) of participants. Overall, the median surgical risk calculator estimated risk of 'serious' and 'any' postoperative complication reduced from 4.8% to 3.9% (P < .001) and 6% to 5.1% (P < .001), respectively. Reduction in all Surgical Risk Calculator scores occurred, including surgical site infection, re-admission, and cardiac events (P < .05).

CONCLUSION

The dietitian-led preoperative, very low calorie diet clinic improved American Society of Anesthesiologists and Surgical Risk Calculator scores for non-bariatric elective surgery patients with obesity. Randomized controlled trials comparing this approach with a control group are warranted.

'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.

TRIAL REGISTRATION NUMBER

NCT05853484.

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.

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.

Effect of exercise interventions on hospital length of stay and admissions during cancer treatment: a systematic review and meta-analysis

OBJECTIVE

To assess the effect of participating in an exercise intervention compared with no exercise during cancer treatment on the duration and frequency of hospital admissions.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

MEDLINE, EMBASE, PEDro and Cochrane Central Registry of Randomized Controlled Trials.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Randomised studies published until August 2023 evaluating exercise interventions during chemotherapy, radiotherapy or stem cell transplant regimens, compared with usual care, and which assessed hospital admissions (length of stay and/or frequency of admissions).

STUDY APPRAISAL AND SYNTHESIS

Study quality was assessed using the Cochrane Risk-of-Bias tool and Grading of Recommendations Assessment, Development and Evaluation assessment. Meta-analyses were conducted by pooling the data using random-effects models.

RESULTS

Of 3918 screened abstracts, 20 studies met inclusion criteria, including 2635 participants (1383 intervention and 1252 control). Twelve studies were conducted during haematopoietic stem cell transplantation regimens. There was a small effect size in a pooled analysis that found exercise during treatment reduced hospital length of stay by 1.40 days (95% CI: -2.26 to -0.54 days; low-quality evidence) and lowered the rate of hospital admission by 8% (difference in proportions=-0.08, 95% CI: -0.13 to -0.03, low-quality evidence) compared with usual care.

CONCLUSION

Exercise during cancer treatment can decrease hospital length of stay and admissions, although a small effect size and high heterogeneity limits the certainty. While exercise is factored into some multidisciplinary care plans, it could be included as standard practice for patients as cancer care pathways evolve.

Recovery of surgery in the elderly (ROSE) program: The efficacy of a multi-modal prehabilitation program implemented in frail and pre-frail elderly undergoing major abdominal surgery

BACKGROUND

Major abdominal surgery is associated with a high rate of post-operative complications with increased risk of adverse surgical outcomes due to the presence of frailty. This study aims to evaluate the effectiveness of the multimodal Recovery of Surgery in the Elderly (ROSE) prehabilitation program with supervised exercise in mitigating postoperative functional decline when compared to standard care.

METHOD

The ROSE program enrolled ambulant patients who were 65 years and above, had a Clinical Frailty Scale score of 4 or more and were planned for major abdominal surgery. Participation in supervised exercise sessions before surgery were compared with standard physiotherapy advice. The primary outcome was 6-min walk test (6MWT) distance assessed at baseline, after prehabilitation and 30 days follow-up after surgery. Secondary outcomes included physical performance, length of hospital stay and postoperative morbidity.

RESULTS

Data from 74 eligible patients, 37 in each group, were included. Median age was 78 years old. Forty-two patients (22 in Prehab group and 20 in control group) with complete 6MWT follow-up data at 30 days follow-up were analysed for outcomes. Most patients underwent laparoscopic surgery (63.5%) and almost all of the surgeries were for abdominal malignancies (97.3%). The Prehab group had an increase in 6MWT distance at the 30-day follow up, from a baseline mean (SD) of 277.4 (125) m to 287.6 (143.5) m (p = 0.415). The 6MWT distance in the control group decreased from a baseline mean (SD) of 281.7 (100.5) m to 260.1 (78.6) m at the 30-day follow up (p = 0.086). After adjusting for baseline 6MWT distance and frailty score, the Prehab group had significantly higher 6MWT distance at 30-day follow-up than control (difference in adjusted means 41.7 m, 95% confidence interval 8.7-74.8 m, p = 0.015). There were no significant between-group differences in the secondary outcomes.

CONCLUSION

A multimodal prehabilitation program with supervised exercise within a short time frame can improve preoperative functional capacity and maintain baseline functional capacity in frail older adults undergoing major abdominal surgery.

A 10-year review on older patients undergoing colorectal cancer surgery: surgeon-led geriatric service and good quality surgery are drivers of good outcomes

BACKGROUND

Older age and frailty are associated with worse postoperative outcomes and prolonged length of stay (LOS). In this study, we aimed to analyze the long-term outcomes after the implementation of our geriatric surgical service (GSS).

METHODS

This was a single-center retrospective study from July 2010 to December 2021 on patients aged ≥75 years or patients aged ≥65 years with frailty. Our GSS includes multidisciplinary assessment and optimization by specialized nurses, physiotherapists, anesthetists, dietitians, and geriatricians. Cumulative sum (CUSUM) analysis was used to assess the performance of our GSS. Our primary outcome was defined as the presence of 30-day mortality, prolonged LOS ≥ 14 days, and/or >10% decrease in the modified Barthel Index at 6 weeks, which depicts the failure of GSS. A downsloping CUSUM curve implies consecutive cases of success.

RESULTS

There were 233 patients with a mean age of 79.0 ± 4.9 years; of these, 73 patients (31.3%) were frail. The overall 30-day mortality (1.7%), Clavien-Dindo ≥ grade IIIA complications (12.0%), and LOS (median, 7.0 days) were low. The CUSUM analysis showed 3 phases with overall sustained improvement in outcomes. Transient inconsistency in the second phase (during midimplementation of GSS) may be due to the early adoption of laparoscopic surgery (44.6% vs 24.1%; adjusted P =.031) and expansion of service to include patients with higher perioperative risks (weighted Charlson Comorbidity Index score ≥4: 64.9% vs 38.0%; adjusted P =.002) in the second period compared with the first period. The outcomes subsequently improved in the third phase after overcoming the learning curve.

CONCLUSION

Our GSS showed sustained performance over the past decade. Good quality surgery and surgeon-led geriatric service are paramount for good postoperative outcomes.

Prehabilitation before general surgery: Worth the effort?

Prehabilitation, or interventions before surgery aimed at improving preoperative health and postoperative outcomes, has various forms. Although it may confer benefit to patients undergoing general surgery, this is not certain. Furthermore, although it may yield a net monetary gain, it is also likely to require substantial monetary and non-monetary investment. The impact of prehabilitation is highly variable and dependent on multiple factors. Physical function and pulmonary outcomes are likely to be improved by most forms of prehabilitation involving physical and multimodal exercise programmes. However, other surgical outcomes have demonstrated mixed results from prehabilitation. Within this issue, the measures used for evaluating baseline patient biopsychosocial health are important, and collecting sufficient data to accurately inform patient-centred prehabilitation programmes is only possible through thorough clinical and laboratory investigation and synthesised metrics such as cardiopulmonary exercise testing. Although a multimodal approach to prehabilitation is the current gold standard, societal factors may affect engagement with programmes that require a significant in-person activity. However, this is weighed against the substantial financial and non-financial investment that accompanies many programmes. The overall effectiveness and optimal mode of intervention across the discipline of general surgery remains unclear, and further research is needed to prove prehabilitation's full worth.

The use of digital technologies to support home-based prehabilitation prior to major surgery: A systematic review

BACKGROUND

Prehabilitation is a multidimensional and multidisciplinary approach, to prepare patients for surgery, with the aim of improving postoperative outcomes. Worldwide, healthcare systems are facing challenges with a gap between demand and supply of healthcare services. Telehealth is seen as a solution for delivering sustainable and efficient treatments. The effect of providing prehabilitation using telehealth solutions is unclear.

OBJECTIVE

This systematic review investigated the existing literature regarding the effects and feasibility of technologies for remotely supporting home-based prehabilitation compared to standard care on pre- and postoperative outcomes in adults undergoing elective major surgery.

METHODS

A literature search identified relevant studies published between 1 January 2012 and December 2022 in PubMed, PsychInfo, Cinahl and the Cochrane Library. We included RCTs, feasibility and pilot studies. The quality of studies was evaluated using Cochrane's Risk of bias assessment and by narratively rating the certainty of evidence.

RESULTS

Six randomized controlled trials and 20 pilot/feasibility studies were included. The number and content of the interventions varied, depending on context and resources. Multiple approaches in the use of digital healthcare solutions were applied and the results highlight the potential of providing health services remotely.

CONCLUSION

The use of technologies to support remote home-based prehabilitation in patients undergoing elective major surgery is feasible and has high acceptability, though telehealth is a broad term and wide-ranging strategies are used. Digital technologies for supporting home-based prehabilitation are likely to play an essential role in future health care as resources are scarce and innovative solutions are needed.

Commentary: Key Aspects of Multimodal Prehabilitation in Surgical Patients With Cancer. A Practical Approach to Integrating Resistance Exercise Programmes

Surgical prehabilitation aims to optimise patients' physiological reserves to better withstand the stress of surgery, reduce the risk of postoperative complications, and promote a faster and optimal recovery. The purpose of this commentary is to outline the key aspects of prehabilitation before surgery for cancer which seem to impact its effectiveness and wider implementation. Particular attention is paid to the role and integration of resistance training programmes as a key component of multimodal prehabilitation for patients with cancer. We firstly analyse some of the barriers currently hindering the implementation of prehabilitation programmes in the National Health Service (United Kingdom). Later, we describe essential aspects of resistance training design, such as exercise modality and order execution, volume and intensity, rest periods between sets or exercises, and workout frequency. Furthermore, we propose a methodology to use the perception of effort to control patients' progression during a prehabilitation programme.

Preoperative multimodal prehabilitation before elective colorectal cancer surgery in patients with WHO performance status I or II: randomized clinical trial

BACKGROUND

Multimodal prehabilitation is a promising adjunct to the current surgical treatment pathway for colorectal cancer patients to further improve postoperative outcomes, especially for high-risk patients with low functional capacity. The aim of the present study was to test the effect of prehabilitation on immediate postoperative recovery.

METHOD

The study was designed as a RCT with two arms (intervention and control). The intervention consisted of 4 weeks of multimodal prehabilitation, with supervised physical training, nutritional support and medical optimization. The control group received standard of care. A total of 40 patients with colorectal cancer (WHO performance status I or II) undergoing elective surgery with curative intent were included. The primary outcome was postoperative recovery within the first 3 postoperative days, measured by Quality of Recovery-15, a validated questionnaire with a scoring range between 0 and 150 and a minimal clinically relevant difference of 8.

RESULTS

In total, 36 patients were analysed with 16 in the intervention group and 20 in the control group. The mean age of the included patients was 79 years. The overall treatment effect associated with the intervention was a 21.9 (95% c.i. 4.5-39.3) higher quality of recovery-15 score during the first 3 postoperative days compared to control, well above the minimal clinically relevant difference.

CONCLUSION

Four weeks of multimodal prehabilitation prior to elective curative intended colorectal cancer surgery in patients with WHO performance status I or II was associated with a clinically relevant improvement in postoperative recovery.Registration number: NCT04167436 (http://www.clinicaltrials.gov).

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.

Sex-related differences in functional capacity and its implications in risk stratification before major non-cardiac surgery: a post hoc analysis of the international METS study

Background

Poor functional capacity has been identified as an important modifiable risk factor for postoperative complications. Cardiopulmonary exercise testing (CPET) provides objective parameters of functional capacity (e.g., oxygen consumption at peak exercise, peak VO2), with significant prognostication for postoperative complications. However, sex-specific thresholds for functional capacity to predict surgical risk are yet to be established. Therefore, we performed a post hoc analysis of the international, multicentre, prospective observational METS (Measurement of Exercise Tolerance before Surgery) study to evaluate if sex-specific thresholds of peak VO2 improve risk prediction of postoperative complications.

Methods

We undertook a post hoc analysis (HREC/71824/PMCC) of the METS study, which was performed between March 2013 and March 2016. We investigated whether sex-specific differences exist for CPET-derived parameters and associated thresholds for predicting postoperative complications in this large cohort of patients that had major non-cardiac surgery (n = 1266). Logistic regression models were analyzed for the association of low peak VO2 with moderate-to-severe in-hospital postoperative complications. Optimal sex-specific peak VO2 thresholds were obtained by maximizing the Youden index of receiver operating characteristic (ROC) curves. Finally, multivariable logistic regression models tested the resulting sex-specific thresholds against the established non-sex-specific peak VO2 threshold (14 mL kg-1 min-1) adjusted for clinically relevant features such as comorbidities and surgical complexity. Models were evaluated by bootstrapping optimism-corrected area under the ROC curve and the net reclassification improvement index (NRI).

Findings

Female patients (n = 480) had a lower mean (SD) peak VO2 than males (16.7 (4.9) mL kg-1 min-1 versus 21.2 (6.5) mL kg-1 min-1, p < 0.001) and a lower postoperative complication rate (10.4% versus 15.3%; p = 0.018) than males (n = 786). The optimal peak VO2 threshold for predicting postoperative complications was 12.4 mL kg-1 min-1 for females and 22.3 mL kg-1 min-1 for males, respectively. In the multivariable regression model, low non-sex-specific peak VO2 did not independently predict postoperative complications. In contrast, low sex-specific peak VO2 was an independent predictor of postoperative complications (OR 2.29; 95% CI: 1.60, 3.30; p < 0.001). The optimism-corrected AUC-ROC of the sex-specific model was higher compared with the non-sex-specific model (0.73 versus 0.7; DeLong's test: p = 0.021). The sex-specific model classified 39% of the patients more correctly than the baseline model (NRI = 0.39; 95% CI: 0.24, 0.55). In contrast, the non-sex-specific model only classified 9% of the patients more correctly when compared against the baseline model (NRI = 0.09; 95% CI: -0.04, 0.22).

Interpretation

Our data report sex-specific differences in preoperative CPET-derived functional capacity parameters. Sex-specific peak VO2 thresholds identify patients at increased risk for postoperative complications with a higher discriminatory ability than a sex-unspecific threshold. As such, sex-specific threshold values should be considered in preoperative CPET to potentially improve risk stratification and to guide surgical decision-making, including eligibility for surgery, preoperative optimization strategies (prehabilitation) or seeking non-surgical options.

Predictors of discharge to home following major surgery for urologic malignancies: Results from the national surgical quality improvement program

OBJECTIVES

To identify patient risk factors that predict nonhome discharge after surgery for urologic malignancies as well as determine whether discharge status had an impact on readmission rates in patients undergoing surgery for urologic malignancies.

METHODS

We identified patients who had undergone surgery for urologic malignancies including prostate, bladder, kidney, or upper tract urothelial cancer from 2011 to 2019 in the American College of Surgeon National Surgical Quality Improvement Program (ACS-NSQIP) database. Multivariable logistic regression analyses were performed to identify patient characteristics that were associated with nonhome discharges and 30-day postoperative readmission.

RESULTS

Nonhome discharge occurred in 2.8% of our study population. Women were less likely to be discharged to home (OR 0.60 p < 0.0001). Nonhome discharge was more common in patients who underwent cystectomy when compared to nephrectomy (OR 1.41 p < 0.0001) or prostatectomy (OR 4.16 p < 0.0001). Those with elevated BMI were less likely to experience non-home discharge (OR 0.86 p=0.0095) while patients who were identified as underweight and those with unexpected weight loss prior to surgery were more likely to have nonhome discharges (OR 1.76 p = 0.0002, OR 1.67, p < 0.0001). Comorbidities and presence of postoperative complications were also found to be significant independent predictors of nonhome discharges. Thirty-day postoperative readmission occurred in 6.9% of our study population. Of the patients who were readmitted 93.1% were initially discharged home, and 6.9% had nonhome discharges. Higher risk of readmission was seen in elderly patients and those with significant comorbidities. When controlling for predictors of readmission, on multivariate analysis, non-home discharge was associated with a decreased likelihood of readmission (OR 0.79, p = 0.0004).

CONCLUSIONS

Patient factors including age, gender, weight, comorbidities, postoperative complications, and site of procedure were found to be independent predictors of non-home discharge following surgery for urologic malignancies. Patients with these risk factors should be counseled preoperatively on the likelihood of requiring a non-home discharge to help manage expectations and create a standardized transition of care pathway following surgery.

Acceptability of prehabilitation for cancer surgery: a multi-perspective qualitative investigation of patient and 'clinician' experiences

BACKGROUND

'Prehabilitation' interventions aim to enhance individuals' physical fitness prior to cancer treatment, typically involve exercise training as a key component, and may continue to support physical activity, strength, and fitness during or after treatment. However, uptake of prehabilitation is variable. This study investigated how patients from diverse socio-economic status groups perceived an exemplar prehabilitation and recovery programme, aiming to understand factors impacting acceptability, engagement and referral.

METHODS

This research was conducted in the context of the Prehab4Cancer and Recovery Programme, a prehabilitation and recovery programme available across Greater Manchester, UK. Qualitative, semi-structured phone/video-call interviews were conducted with 18 adult patient participants referred to the programme (16 'engagers', 2 'non-engagers'; half the sample lived in localities with low socio-economic status scores). An online questionnaire with free-response and categorical-response questions was completed by 24 'clinician' participants involved in referral (nurses, doctors and other staff roles). An inductive, multi-perspective, thematic analysis was performed, structured using the Framework approach.

RESULTS

Discussing and referring patients to prehabilitation can be challenging due to large quantities of information for staff to cover, and for patients to absorb, around the time of diagnosis. The programme was highly valued by both participant groups; the belief that participation would improve recovery seemed a major motivator for engagement, and some 'clinicians' felt that prehabilitation should be treated as a routine part of treatment, or extended to support other patient groups. Engagers seemed to appreciate a supportive approach where they did not feel forced to do any activity and tailoring of the programme to meet individual needs and abilities was appreciated. Initial engagement could be daunting, but gaining experience with the programme seemed to increase confidence.

CONCLUSIONS

The prehabilitation programme was highly valued by engagers. Introducing prehabilitation at a challenging time means that personalised approaches might be needed to support engagement, or participation could be encouraged at a later time. Strategies to support individuals lacking in confidence, such as buddying, may be valuable.

A comparative analysis of the Hospital Frailty Risk Score in predicting postoperative outcomes among intracranial tumor patients

OBJECTIVE

In recent years, frailty indices such as the 11- and 5-factor modified frailty indices (mFI-11 and mFI-5), American Society of Anesthesiologists (ASA) physical status classification, and Charlson Comorbidity Index (CCI) have been shown to be effective predictors of various postoperative outcomes in neurosurgical patients. The Hospital Frailty Risk Score (HFRS) is a well-validated tool for assessing frailty; however, its utility has not been evaluated in intracranial tumor surgery. In the present study, the authors investigated the accuracy of the HFRS in predicting outcomes following intracranial tumor resection and compared its utility to those of other validated frailty indices.

METHODS

A retrospective analysis was conducted using an intracranial tumor patient database at a single institution. Patients eligible for study inclusion were those who had undergone resection for an intracranial tumor between January 1, 2017, and December 31, 2019. ICD-10 codes were used to identify HFRS components and subsequently calculate risk scores. In addition to several postoperative variables, ASA class, CCI, and mFI-11 and mFI-5 scores were determined for each patient. Model discrimination was assessed using the area under the receiver operating characteristic curve (AUROC), and the DeLong test was used to assess for significant differences between AUROCs. Multivariate models for continuous outcomes were constructed using linear regression, whereas logistic regression models were used for categorical outcomes.

RESULTS

A total of 2518 intracranial tumor patients (mean age 55.3 ± 15.1 years, 53.4% female, 70.4% White) were included in this study. The HFRS had a statistically significant greater AUROC than ASA status, CCI, mFI-11, and mFI-5 for postoperative complications, high hospital charges, nonroutine discharge, and 90-day readmission. In the multivariate analysis, the HFRS was significantly and independently associated with postoperative complications (OR 1.14, p < 0.0001), hospital length of stay (coefficient = 0.50, p < 0.0001), high hospital charges (coefficient = 1917.49, p < 0.0001), nonroutine discharge (OR 1.14, p < 0.0001), and 90-day readmission (OR 1.06, p < 0.0001).

CONCLUSIONS

The study findings suggest that the HFRS is an effective predictor of postoperative outcomes in intracranial tumor patients and more effectively predicts adverse outcomes than other frailty indices. The HFRS may serve as an important tool for reducing patient morbidity and mortality in intracranial tumor surgery.

Guidelines on perioperative optimization protocol for the adult patient 2023

OBJECTIVE

The French Society of Anesthesiology and Intensive Care Medicine [Société Française d'Anesthésie et de Réanimation (SFAR)] aimed at providing guidelines for the implementation of perioperative optimization programs.

DESIGN

A consensus committee of 29 experts from the SFAR was convened. A formal conflict-of-interest policy was developed at the outset of the process and enforced throughout. The entire guidelines process was conducted independently of any industry funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence.

METHODS

Four fields were defined: 1) Generalities on perioperative optimization programs; 2) Preoperative measures; 3) Intraoperative measures and; 4) Postoperative measures. For each field, the objective of the recommendations was to answer a number of questions formulated according to the PICO model (population, intervention, comparison, and outcomes). Based on these questions, an extensive bibliographic search was carried out using predefined keywords according to PRISMA guidelines and analyzed using the GRADE® methodology. The recommendations were formulated according to the GRADE® methodology and then voted on by all the experts according to the GRADE grid method. As the GRADE® methodology could have been fully applied for the vast majority of questions, the recommendations were formulated using a "formalized expert recommendations" format.

RESULTS

The experts' work on synthesis and application of the GRADE® method resulted in 30 recommendations. Among the formalized recommendations, 19 were found to have a high level of evidence (GRADE 1±) and ten a low level of evidence (GRADE 2±). For one recommendation, the GRADE methodology could not be fully applied, resulting in an expert opinion. Two questions did not find any response in the literature. After two rounds of rating and several amendments, strong agreement was reached for all the recommendations.

CONCLUSIONS

Strong agreement among the experts was obtained to provide 30 recommendations for the elaboration and/or implementation of perioperative optimization programs in the highest number of surgical fields.

European Society of Organ Transplantation (ESOT) Consensus Statement on Prehabilitation for Solid Organ Transplantation Candidates

There is increasingly growing evidence and awareness that prehabilitation in waitlisted solid organ transplant candidates may benefit clinical transplant outcomes and improve the patient's overall health and quality of life. Lifestyle changes, consisting of physical training, dietary management, and psychosocial interventions, aim to optimize the patient's physical and mental health before undergoing surgery, so as to enhance their ability to overcome procedure-associated stress, reduce complications, and accelerate post-operative recovery. Clinical data are promising but few, and evidence-based recommendations are scarce. To address the need for clinical guidelines, The European Society of Organ Transplantation (ESOT) convened a dedicated Working Group "Prehabilitation in Solid Organ Transplant Candidates," comprising experts in physical exercise, nutrition and psychosocial interventions, to review the literature on prehabilitation in this population, and develop recommendations. These were discussed and voted upon during the Consensus Conference in Prague, 13-15 November 2022. A high degree of consensus existed amongst all stakeholders including transplant recipients and their representatives. Ten recommendations were formulated that are a balanced representation of current published evidence and real-world practice. The findings and recommendations of the Working Group on Prehabilitation for solid organ transplant candidates are presented in this article.

Is personalised prehabilitation feasible to implement for patients undergoing oncological treatment for lung cancer at a London teaching hospital? Protocol of a feasibility trial

INTRODUCTION

There is significant potential to improve outcomes for patients with lung cancer in terms of quality of life and survival. There is some evidence that prehabilitation can help, but, to date, this has only been tested in surgical populations, despite 70%-80% of patients with lung cancer in the UK receiving non-surgical treatment. The physiological and psychological benefits of prehabilitation seen in surgical patients could be extrapolated to those receiving non-surgical treatment, particularly in such a poor prognosis group. With patients and healthcare professionals, we have co-designed a personalised and evidence-based prehabilitation programme. This draws on a conceptual framework that aligns with patient values and needs as well as functional goals. We aim to investigate whether this programme is feasible to implement and evaluate in clinical practice.

METHODS AND ANALYSIS

An open-label, single-group feasibility study incorporating quantitative assessments, a qualitative free text questionnaire and reflective field notes. Thirty participants will be recruited over an eight-month period from a single London teaching hospital. All recruited participants will receive a personalised prehabilitation programme during their oncological treatment. This includes a one-hour face-to-face appointment prior to, at week three and at week six of their treatment regimen as well as a weekly telephone call. Interventions including nutrition, physical activity and psychological well-being are stratified according to a patient's priorities, level of readiness and expressed needs. The primary outcome will be feasibility of the personalised prehabilitation programme in clinical practice by investigating areas of uncertainty regarding patient recruitment, attrition, treatment fidelity, intervention adherence and acceptability of study outcome measures. Secondary outcomes will include quality of life, functional capacity and grip strength.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Health Research Authority (reference number 22/PR/0390). Results of this study will be disseminated through publication in peer-reviewed articles, presentations at scientific conferences and in collaboration with patient and public involvement representatives.

Old Age and Frailty in Deceased Organ Transplantation and Allocation-A Plea for Geriatric Assessment and Prehabilitation

Due to demographic ageing and medical progress, the number and proportion of older organ donors and recipients is increasing. At the same time, the medical and ethical significance of ageing and old age for organ transplantation needs clarification. Advanced age is associated with the frailty syndrome that has a negative impact on the success of organ transplantation. However, there is emerging evidence that frailty can be modified by suitable prehabilitation measures. Against this backdrop, we argue that decision making about access to the transplant waiting list and the allocation of donor organs should integrate geriatric expertise in order to assess and manage frailty and impairments in functional capacity. Prehabilitation should be implemented as a new strategy for pre-operative conditioning of older risk patients' functional capacity. From an ethical point of view, advanced chronological age per se should not preclude the indication for organ transplantation and the allocation of donor organs.

The effect of preoperative behaviour change interventions on pre- and post-surgery health behaviours, health outcomes, and health inequalities in adults: A systematic review and meta-analyses

BACKGROUND

Prehabilitation interventions are being delivered across surgical specialities to improve health risk behaviours leading to better surgical outcomes and potentially reduce length of hospital stay. Most previous research has focused on specific surgery specialities and has not considered the impact of interventions on health inequalities, nor whether prehabilitation improves health behaviour risk profiles beyond surgery. The aim of this review was to examine behavioural Prehabilitation interventions across surgeries to inform policy makers and commissioners of the best available evidence.

METHODS AND FINDINGS

A systematic review and meta-analysis of randomised controlled trials (RCTs) was conducted to determine the effect of behavioural prehabilitation interventions targeting at least one of: smoking behaviour, alcohol use, physical activity, dietary intake (including weight loss interventions) on pre- and post-surgery health behaviours, health outcomes, and health inequalities. The comparator was usual care or no treatment. MEDLINE, PubMed, PsychINFO, CINAHL, Web of Science, Google Scholar, Clinical trials and Embase databases were searched from inception to May 2021, and the MEDLINE search was updated twice, most recently in March 2023. Two reviewers independently identified eligible studies, extracted data, and assessed risk of bias using the Cochrane risk of bias tool. Outcomes were length of stay, six-minute walk test, behaviours (smoking, diet, physical activity, weight change, and alcohol), and quality of life. Sixty-seven trials were included; 49 interventions targeted a single behaviour and 18 targeted multiple behaviours. No trials examined effects by equality measures. Length of stay in the intervention group was 1.5 days shorter than the comparator (n = 9 trials, 95% CI -2.6 to -0.4, p = 0.01, I2 83%), although in sensitivity analysis prehabilitation had the most impact in lung cancer patients (-3.5 days). Pre-surgery, there was a mean difference of 31.8 m in the six-minute walk test favouring the prehabilitation group (n = 19 trials, 95% CI 21.2 to 42.4m, I2 55%, P <0.001) and this was sustained to 4-weeks post-surgery (n = 9 trials, mean difference = 34.4m (95%CI 12.8 to 56.0, I2 72%, P = 0.002)). Smoking cessation was greater in the prehabilitation group before surgery (RR 2.9, 95% CI 1.7 to 4.8, I2 84%), and this was sustained at 12 months post-surgery (RR 1.74 (95% CI 1.20 to 2.55, I2 43%, Tau2 0.09, p = 0.004)There was no difference in pre-surgery quality of life (n = 12 trials) or BMI (n = 4 trials).

CONCLUSIONS

Behavioural prehabilitation interventions reduced length of stay by 1.5 days, although in sensitivity analysis the difference was only found for Prehabilitation interventions for lung cancer. Prehabilitation can improve functional capacity and smoking outcomes just before surgery. That improvements in smoking outcomes were sustained at 12-months post-surgery suggests that the surgical encounter holds promise as a teachable moment for longer-term behavioural change. Given the paucity of data on the effects on other behavioural risk factors, more research grounded in behavioural science and with longer-term follow-up is needed to further investigate this potential.

Collaboration for Evidence-based Practice and Research in Anaesthesia (CEPRA): A consortium initiative for perioperative research

Evidence in perioperative care is insufficient. There is an urgent need for large perioperative research programmes, including pragmatic randomised trials, testing daily clinical treatments and unanswered question, thereby providing solid evidence for effects of interventions given to a large and growing number of patients undergoing surgery and anaesthesia. This may be achieved through large collaborations. Collaboration for Evidence-based Practice and Research in Anaesthesia (CEPRA) is a novel collaborative research network founded to pursue evidence-based answers to major clinical questions in perioperative medicine. The aims of CEPRA are to (1) improve clinical treatment and outcomes and optimise the use of resources for patients undergoing anaesthesia and perioperative care, and (2) disseminate results and inform caretakers, patients and relatives, and policymakers of evidence-based treatments in anaesthesia and perioperative medicine. CEPRA is inclusive in its concept. We aim to extend our collaboration with all relevant clinical collaborators and patient associations and representatives. Although initiated in Denmark, CEPRA seeks to develop an international network infrastructure, for example, with other Nordic countries. The work of CEPRA will follow the highest methodological standards. The organisation aims to structure and optimise any element of the research collaboration to reduce economic costs and harness benefits from well-functioning research infrastructure. This includes successive continuation of trials, harmonisation of outcomes, and alignment of data management systems. This paper presents the initiation and visions of the CEPRA network. CEPRA aims to be inclusive, patient-focused, methodologically sound, and to optimise all aspects of research logistics. This will translate into faster research conduct, reliable results, and accelerated clinical implementation of results, thereby benefiting millions of patients whilst being cost and labour-saving.

A toolbox for a structured risk-based prehabilitation program in major surgical oncology

Prehabilitation is a multimodal concept to improve functional capability prior to surgery, so that the patients' resilience is strengthened to withstand any peri- and postoperative comorbidity. It covers physical activities, nutrition, and psychosocial wellbeing. The literature is heterogeneous in outcomes and definitions. In this scoping review, class 1 and 2 evidence was included to identify seven main aspects of prehabilitation for the treatment pathway: (i) risk assessment, (ii) FITT (frequency, interventions, time, type of exercise) principles of prehabilitation exercise, (iii) outcome measures, (iv) nutrition, (v) patient blood management, (vi) mental wellbeing, and (vii) economic potential. Recommendations include the risk of tumor progression due to delay of surgery. Patients undergoing prehabilitation should perceive risk assessment by structured, quantifiable, and validated tools like Risk Analysis Index, Charlson Comorbidity Index (CCI), American Society of Anesthesiology Score, or Eastern Co-operative Oncology Group scoring. Assessments should be repeated to quantify its effects. The most common types of exercise include breathing exercises and moderate- to high-intensity interval protocols. The program should have a duration of 3-6 weeks with 3-4 exercises per week that take 30-60 min. The 6-Minute Walking Testing is a valid and resource-saving tool to assess changes in aerobic capacity. Long-term assessment should include standardized outcome measurements (overall survival, 90-day survival, Dindo-Clavien/CCI®) to monitor the potential of up to 50% less morbidity. Finally, individual cost-revenue assessment can help assess health economics, confirming the hypothetic saving of $8 for treatment for $1 spent for prehabilitation. These recommendations should serve as a toolbox to generate hypotheses, discussion, and systematic approaches to develop clinical prehabilitation standards.

Efficacy of supervised exercise prehabilitation programs to improve major abdominal surgery outcomes: A systematic review and meta-analysis

The optimal package of components for a prehabilitation intervention remains unclear. The aim was to determine the efficacy of supervised exercise prehabilitation programs to enhance patient fitness and improve surgical outcomes. The protocol was preregistered (PROSPERO: CRD42020180693). PubMed, MEDLINE, CINAHL, AMED, CENTRAL, PeDro, ClinicalTrials.gov and the WHO International Clinical Trials Registry were searched. Randomized controlled trials (RCTs) of supervised prehabilitation programs before major abdominal surgery were included. Physical function, cardiorespiratory capacity and surgical outcomes were the primary outcomes measures. Risk of bias was assessed according to the Cochrane Risk of Bias 1.0 tool for RCTs. Data are summarized narratively, and where possible, quantitavely. Meta-analyses results are reported as risk ratios (RR), mean difference of changes between baseline and follow-up time points or mean difference between groups and 95% confidence interval (CI). Twenty RCTs were included in the analysis with a total of 1258 patients. The average 6-min walking distance change was +33 m in the prehabilitation group compared to the usual care (UC) group after prehabilitation (95% CI: [13, 53], P < 0.01). Only in studies with more than one supervised session per week changes in 6-min-walk distance were significantly higher in the prehabilitation group compared to the UC group after prehabiliatation (Mean difference: 47 m, 95% [CI]: [20-75], P < 0.01). The change in peak volume of oxygen uptake during a maximum cardiopulmonary test was +1.47 mL·kg^-1·min^-1 in the prehabilitation group compared to the UC group (95% CI: [0.68, 2.25], P < 0.01). There was no significant difference in the change in oxygen uptake at anaerobic threshold between groups (Mean differences: 0.47, 95% CI: [-0.16, 1.10], P:0.14). Post-operative complications incidence was similar between groups (RR: 0.80, 95% CI: [0.61, 1.05], P:0.11), irrespective of the frequency of supervised session per week (RR: 0.67, 95% CI: [0.43, 1.03], P:0.07). In conclusion, prehabilitation programmes with more than one supervised session per week improved physical function but did not enhance surgical outcomes.

Time to surgery is not an oncological risk factor in HCC patients undergoing liver resection

PURPOSE

Given limitations of the health care systems in case of unforeseeable events, e.g., the COVID pandemic as well as trends in prehabilitation, time from diagnosis to surgery (time to surgery, (TTS)) has become a research issue in malignancies. Thus, we investigated whether TTS is associated with oncological outcome in HCC patients undergoing surgery.

METHODS

A monocentric cohort of 217 patients undergoing liver resection for HCC between 2009 and 2021 was analyzed. Individuals were grouped according to TTS and compared regarding clinical characteristics. Overall survival (OS) and recurrence-free survival (RFS) was compared using Kaplan-Meier analysis and investigated by univariate and multivariable Cox regressions.

RESULTS

TTS was not associated with OS (p=0.126) or RFS (p=0.761) of the study cohort in univariate analysis. In multivariable analysis age (p=0.028), ASA (p=0.027), INR (0.016), number of HCC nodules (p=0.026), microvascular invasion (MVI; p<0.001), and postoperative complications (p<0.001) were associated with OS and INR (p=0.005), and number of HCC nodules (p<0.001) and MVI (p<0.001) were associated with RFS. A comparative analysis of TTS subgroups was conducted (group 1, ≤30 days, n=55; group 2, 31-60 days, n=79; group 3, 61-90 days, n=45; group 4, >90 days, n=38). Here, the median OS were 62, 41, 38, and 40 months (p=0.602 log rank) and median RFS were 21, 26, 26, and 25 months (p=0.994 log rank). No statistical difference regarding oncological risk factors were observed between these groups.

CONCLUSION

TTS is not associated with earlier tumor recurrence or reduced overall survival in surgically treated HCC patients.

Multimodal prehabilitation service for patients with colorectal cancer: the challenges of implementation

Prehabilitation has been shown to improve outcomes for patients undergoing major surgery; benefits include reductions in length of hospital stay and postoperative complications. Multimodal prehabilitation programmes lead to improved patient engagement and experience. This report describes implementation of a personalised multimodal prehabilitation programme for patients awaiting colorectal cancer surgery. We aim to highlight the successes, challenges and future direction of our programme.Patients listed for colorectal cancer surgery were referred for initial prehabilitation assessment. The prehabilitation group were assessed by specialist physiotherapists, dieticians and psychologists. An individualised programme was developed for each patient, aiming to optimise preoperative functional capacity and enhance physical and psychological resilience. Clinical primary outcome measures were recorded and compared with contemporaneous controls. For those undergoing prehabilitation, a set of secondary functional, nutritional and psychological outcomes were recorded at initial assessment and on completion of the programme.61 patients were enrolled in the programme from December 2021 to October 2022. 12 patients were excluded as they received less than 14 days prehabilitation or had incomplete data. The remaining 49 patients received a median duration of 24 days prehabilitation (range 15-91 days). The results show statistically significant improvements in the following functional outcome measures after prehabilitation: Rockwood scores, maximal inspiratory pressures, International Physical Activity Questionnaire Score and Functional Assessment of Chronic Illness - Fatigue Score. There was a lower postoperative complication rate in the prehabilitation group when compared with a control group (50% vs 67%).This quality improvement project has 3 Plan-Do-Study-Act (PDSA) cycles. PDSA 1 demonstrates prehabilitation can be successfully imbedded within a colorectal surgical unit and that patients are grateful for the service. PDSA 2 provides the project's first complete data set and demonstrates functional improvements in patients undergoing prehabilitation. The third PDSA cycle is ongoing and aims to refine the prehabilitation interventions and improve clinical outcomes for patients undergoing colorectal cancer surgery.

Study protocol for a pilot trial analysing the usability, validity and safety of an interventional health app programme for the structured prehabilitation of patients before major surgical interventions: the PROTEGO MAXIMA trial

INTRODUCTION

Major surgery is associated with a high risk for postoperative complications, leading to an increase in mortality and morbidity, particularly in frail patients with a reduced cardiopulmonary reserve. Prehabilitation, including aerobic exercise training, aims to improve patients' physical fitness before major surgery and reduce postoperative complications, length of hospital stay and costs. The purpose of the study is to assess the usability, validity and safety of an app-based endurance exercise software in accordance with the Medical Device Regulation using wrist-worn wearables to measure heart rate (HR) and distance.

METHODS AND ANALYSIS

The PROTEGO MAXIMA trial is a prospective, interventional study with patients undergoing major elective surgery, comprising three tasks. Tasks I and II aim to assess the usability of the app, using evaluation questionnaires and usability scenarios. In Task IIIa, patients will undergo a structured risk assessment by the Patronus App, which will be correlated with the occurrence of postoperative complications after 90 days (non-interventional). In Task IIIb, healthy students and patients will perform a supervised 6 min walking test and a 37 min interval training on a treadmill based on HR reserve, wearing standard ECG limb leads and two smartwatches, which will be driven by the test software. The aim of this task is to assess the accuracy of HR measurement by the wearables and the safety, using specific alarm settings of the devices and lab testing of the participants (interventional).

ETHICS AND DISSEMINATION

Ethical approval was granted by the Institutional Review Board of the University Hospital of Frankfurt and by the Federal Institute for Pharmaceuticals and Medical Products (BfArM, reference number 94.1.04-5660-13655) on 7 February 2022. The results from this study will be submitted to peer-reviewed journals and reported at suitable national and international meetings.

Adherence to fast track measures in colorectal surgery-a survey among German and Austrian surgeons

PURPOSE

The effectiveness of modern perioperative treatment concepts has been demonstrated in several studies and meta-analyses. Despite good evidence, limited implementation of the fast track (FT) concept is still a widespread concern. To assess the status quo in Austrian and German hospitals, a survey on the implementation of FT measures was conducted among members of the German Society of General and Visceralsurgery (DGAV), the German Society of Coloproctology (DGK) and the Austrian Society of Surgery (OEGCH) to analyze where there is potential for improvement.

METHODS

Twenty questions on perioperative care of colorectal surgery patients were sent to the members of the DGAV, DGK and OEGCH using the online survey tool SurveyMonkey®. Descriptive data analysis was performed using Microsoft Excel.

RESULTS

While some of the FT measures have already been routinely adopted in clinical practice (e.g. minimally invasive surgical approach, early mobilization and diet buildup), for other components there are discrepancies between current recommendations and present implementation (e.g. the use of local nerve blocks to provide opioid-sparing analgesia or the use of abdominal drains).

CONCLUSION

The implementation of the FT concept in Austria and Germany is still in need of improvement. Particularly regarding the use of abdominal drains and postoperative analgesia, there is a tendency to stick to traditional structures. To overcome the issues with FT implementation, the development of an evidence-based S3 guideline for perioperative care, followed by the founding of a surgical working group to conduct a structured education and certification process, may lead to significant improvements in perioperative patient care.

Surgical Prehabilitation in Patients with Gastrointestinal Cancers: Impact of Unimodal and Multimodal Programs on Postoperative Outcomes and Prospects for New Therapeutic Strategies-A Systematic Review

The advantages of prehabilitation in surgical oncology are unclear. This systematic review aims to (1) evaluate the latest evidence of preoperative prehabilitation interventions on postoperative outcomes after gastrointestinal (GI) cancer surgery and (2) discuss new potential therapeutic targets as part of prehabilitation. Randomized controlled trials published between January 2017 and August 2022 were identified through Medline. The population of interest was oncological patients undergoing GI surgery. Trials were considered if they evaluated prehabilitation interventions (nutrition, physical activity, probiotics and symbiotics, fecal microbiota transplantation, and ghrelin receptor agonists), alone or combined, on postoperative outcomes. Out of 1180 records initially identified, 15 studies were retained. Evidence for the benefits of unimodal interventions was limited. Preoperative multimodal programs, including nutrition and physical activity with or without psychological support, showed improvement in postoperative physical performance, muscle strength, and quality of life in patients with esophagogastric and colorectal cancers. However, there was no benefit for postoperative complications, hospital length of stay, hospital readmissions, and mortality. No trial evaluated the impact of fecal microbiota transplantation or oral ghrelin receptor agonists. Further studies are needed to confirm our findings, identify patients who are more likely to benefit from surgical prehabilitation, and harmonize interventions.

Multimodal Prehabilitation in Patients Undergoing Complex Colorectal Surgery, Liver Resection, and Hyperthermic Intraperitoneal Chemotherapy (HIPEC): A Pilot Study on Feasibility and Potential Efficacy

BACKGROUND

Surgery for complex primary and metastatic colorectal cancer (CRC), such as liver resection and hyperthermic intraperitoneal chemotherapy (HIPEC), in academic settings has led to improved survival but is associated with complications up to 75%. Prehabilitation has been shown to prevent complications in non-academic hospitals. This pilot study aimed to determine the feasibility and potential efficacy of a multimodal prehabilitation program in patients undergoing surgery in an academic hospital for complex primary and metastatic CRC.

METHODS

All patients awaiting complex colorectal surgery, liver resection, or HIPEC from July 2019 until January 2020 were considered potentially eligible. Feasibility was measured by accrual rate, completion rate, adherence to the program, satisfaction, and safety. To determine potential efficacy, postoperative outcomes were compared with a historical control group.

RESULTS

Sixteen out of twenty-five eligible patients (64%) commenced prehabilitation, and fourteen patients fully completed the intervention (88%). The adherence rate was 69%, as 11 patients completed >80% of prescribed supervised trainings. No adverse events occurred, and all patients expressed satisfaction with the program. The complication rate was significantly lower in the prehabilitation group (37.5%) than the control group (70.2%, p = 0.020). There was no difference in the type of complications.

CONCLUSION

This pilot study illustrates that multimodal prehabilitation is feasible in the majority of patients undergoing complex colorectal cancer, liver resection, and HIPEC in an academic setting.

Impact of Variations in the Nursing Care Supply-Demand Ratio on Postoperative Outcomes and Costs

INTRODUCTION

Improving surgical outcomes is a priority during the last decades because of the rising economic health care burden. The adoption of enhanced recovery programs has been proven to be part of the solution. In this context, the impact of variations in the nursing care supply-demand ratio on postoperative complications and its economic consequences is still not well elucidated. Because patients require different amounts of care, the present study focused on the more accurate relationship between demand and supply of nursing care rather than the nurse-to-patient ratio.

METHODS

Through a 3-year period, 838 patients undergoing elective and emergent colorectal and pancreatic surgery within the institutional enhanced recovery after surgery (ERAS) protocol were retrospectively investigated. Nursing demand and supply estimations were calculated using a validated program called the Projet de Recherche en Nursing (PRN), which assigns points to each patient according to the nursing care they need ( estimated PRN) and the actual care they received ( real PRN), respectively. The real/estimated PRN ratio was used to create 2 patient groups: one with a PRN ratio higher than the mean (PRN+) and a second with a PRN ratio below the mean (PRN-). These 2 groups were compared regarding their postoperative complication rates and cost-revenue characteristics.

RESULTS

The mean PRN ratio was 0.81. A total of 710 patients (84.7%) had a PRN+ ratio, and 128 (15.3%) had a PRN- ratio. Multivariable analysis focusing on overall complications, severe complications, and prolonged length of stay revealed no significant impact of the PRN ratio for all outcomes ( P > 0.2). The group PRN- had a mean margin per patient of U.S. dollars 1426 (95% confidence interval, 3 to 2903) compared with a margin of U.S. dollars 676 (95% confidence interval, -2213 to 3550) in the PRN+ group ( P = 0.633).

CONCLUSIONS

A PRN ratio of 0.8 may be sufficient for patients treated following enhanced recovery after surgery guidelines, pending the adoption of an accurate nursing planning system. This may contribute to better allocation of nursing resources and optimization of expenses on the long run.

Pulmonary prehabilitation and smoking cessation

PURPOSE OF REVIEW

This review aims to summarize the current literature on pulmonary prehabilitation programs, their effects on postoperative pulmonary complications, and the financial implications of implementing these programs. Additionally, this review has discussed the current trends in pulmonary prehabilitation programs, techniques for improving rates of perioperative smoking cessation, and the optimal timing of these interventions.

RECENT FINDINGS

Prehabilitation is a series of personalized multimodal interventions tailored to individual needs, including lifestyle and behavioral measures. Pulmonary prehabilitation has shown to reduce postoperative pulmonary complications (PPCs).

SUMMARY

The implications of clinical practice and research findings regarding PPCs are an increased burden of postoperative complications and financial cost to both patients and hospital systems. There is convincing evidence that pulmonary prehabilitation based on endurance training should be started 8-12 weeks prior to major surgery; however, similar rates of improved postoperative outcomes are observed with high-intensity interval training (HIIT) for 1-2 weeks. This shorter interval of prehabilitation may be more appropriate for patients awaiting thoracic surgery, especially for cancer resection. Additionally, costs associated with creating and maintaining a prehabilitation program are mitigated by shortened lengths of stay and reduced PPCs.

Multimodal prehabilitation program valuation for thoracic surgical patients

PURPOSE OF REVIEW

Modifiable patient-related risk factors, such as physical, emotional, and cognitive frailty, poor nutritional status, sleep hygiene, anemia, alcohol abuse, and smoking reduce a patient's ability to effectively recover from the insult of surgery. Herein, we review the value of implementing a comprehensive prehabilitation program for patients undergoing thoracic surgery.

RECENT FINDINGS

Although prehabilitation is not a novel concept, recent evidence suggest that 4-6 weeks of prehabilitation prior to surgery is likely to increase a patient's preoperative functional status allowing patients to return to independence earlier after surgery. The value of a prehabilitation program can be determined using cost effectiveness analysis, cost-benefit analysis (CBA), cost-utility analysis (CUA), and cost-consequence analysis (CCA).

SUMMARY

It stands to reason that well designed prehabilitation programs can add value by improving quality metrics at a lower cost to our healthcare system. Definitive randomized trials are needed to confirm this notion.

Outcomes of a Multi-Modal Hospital-Associated Home-Based Cancer Prehabilitation Program

OBJECTIVE

To assess the impact of a "one-stop", multi-modal, hospital-associated-home-based prehabilitation model, helmed by a small core team, on newly diagnosed gastrointestinal and urological cancer patients planned for surgery.

METHODS

This is a retrospective study in a tertiary public hospital, involving all newly diagnosed gastrointestinal and urological cancer patients planned for surgery. The primary outcome measure was the 6-minute walk test (6MWT). Other outcomes included physical, psychological and quality-of-life measures, and patient satisfaction surveys, taken at baseline, pre-operatively (post-prehabilitation), and at 3 months post-operatively.

RESULTS

When comparing the baseline to pre-operatively (post-prehabilitation), there was a statistically significant improvement in the 6MWT (21.52 m, p<0.001), 30-Second Sit to Stand test (STS) (1.08 repetitions, p<0.001), Timed Up and Go test (TUG) (0.83 seconds, p=0.014) and Hospital Anxiety and Depression Scale (HADS) (total score 1.77, p<0.001). These were sustained (6MWT: 0.22, p=0.964; STS: 0.08 repetitions, p=0.863; TUG: 0.04 seconds, p=0.939) or further improved (HADS total score 2.06, p=0.003) at 3 months post-operatively. There was also a statistically significant improvement in the EuroQol-5 dimension health score (health-related quality-of-life measure) from baseline to 3 months post-operatively (7.04 points, p=0.001), with more than 90% overall patient satisfaction reported.

CONCLUSION

Prehabilitation applied via our model resulted in significant improvements in functional capacity, psychological and quality-of-life outcomes, sustained at 3 months post-operatively, and is a feasible and effective approach that is well-received by our patients.
