Home-based prehabilitation with exercise to improve postoperative recovery for older adults with frailty having cancer surgery: the PREHAB randomised clinical trial

Prehabilitation in surgery - an update with a focus on nutrition

PURPOSE OF REVIEW

Since the introduction of the prehabilitation concept for optimizing functional capacity before surgery 20 years ago, evidence and interest has grown considerably. This review summarizes the recent evidence and proposes questions for prehabilitation with special regard to the nutritional component.

RECENT FINDINGS

Several meta-analyses of multimodal prehabilitation (exercise, nutrition, and psychological support) have been published recently. These reviews suggest that preoperative conditioning can improve functional capacity and reduce the complication rate for many patient groups (risk of bias: moderate to low). A prerequisite is the identification of high-risk patients using suitable screening and assessment tools. Additionally, there are currently no standardized, clear recommendations for the organization and implementation of prehabilitation programs. The programs vary greatly in duration, content, and outcome measurement. Although the preoperative nutrition interventions enhanced outcomes consistently, there was no clear evidence for which nutritional intervention should be applied to whom over consistent time frame four to six weeks (timeframe consistent with most prehabilitation programs).

SUMMARY

To advance our understanding of which prehabilitation interventions work best, how they work, and for whom they work best, additional low risk of bias and adequately powered trials are required. Nevertheless, our review presents evidence that prehabilitation should be offered before major surgery on a risk-stratified basis.

Association of cancer with functional decline at old age: a longitudinal study in Danish twins

INTRODUCTION

There is evidence that older adults with cancer have a higher risk of functional decline than cancer-free older adults. However, few studies are longitudinal, and none are twin studies. Thus, we aimed to investigate the relationship between cancer and functional decline in older adult (aged 70+ years) twins.

MATERIALS AND METHODS

Cancer cases in the Longitudinal Study of Aging Danish Twins were identified through the Danish Cancer Registry. Functional status was assessed using hand grip strength (6 years follow-up), and self-reported questions on mobility (10 years follow-up), and cut-offs were defined to assess functional decline. Cox regression models were performed for all the individual twins. In addition, we extended the analysis to discordant twin pairs (twin pairs with one having cancer and the other being cancer-free), to control to a certain extent for (unmeasured) shared confounders (genetic and environmental factors).

RESULTS

The analysis based on individual twins showed that individual twins with cancer are at increased hazard of worsening hand grip strength (hazard ratio (HR) 1.37, 95% confidence interval (CI) 1.04, 1.80) than cancer-free twins. Among the discordant twin pairs, twins with cancer had a higher hazard of worsening hand grip strength (HR 3.50, 95% CI 1.15, 10.63) than cancer-free cotwins. In contrast, there was no evidence of a difference between the hazard of experiencing mobility decline for twins with cancer compared with cancer-free twins, in both individual twins and discordant twin pairs analyses.

DISCUSSION

Cancer was associated with hand grip strength functional decline in old individual twins and discordant pairs. Our results strengthen the importance of comprehensive geriatric assessment in older adults with cancer, as well as the importance of routine assessment of functional status. Promoting physical activity through exercise training programmes could enable the prevention of functional decline in older adults with cancer.

Fit4Surgery app: Home-based prehabilitation app for older patients undergoing elective colorectal cancer surgery

BACKGROUND

Supervised multimodal prehabilitation prior to colorectal cancer (CRC) surgery is associated with reduced complications and enhanced recovery. However, it is labor intensive and expensive. In an aging population with increasing demand and costs on healthcare and staff shortages, home-based prehabilitation (HBP) with an app could be of interest. This study assessed the effectiveness of a Fit4Surgery app in CRC surgery.

METHOD

The app was effectuated in a prospective cohort study of 100 CRC patients ≥60 years from October 2021-December 2022. The primary outcome was preservation or improvement of the 6-minute walking test (6MWT) six weeks postoperative, compared to baseline. Secondary outcomes were 90-day complication and mortality rate, 90-day readmission, length of stay, 6MWT and Short Performance Physical Battery (SPPB) at different timepoints and total costs.

RESULTS

Three patients needed urgent surgery, remaining 97 patients (mean age 72) using the app for at least three weeks. The 6MWT was preserved in 74.7 % with a 12.1 m higher mean six weeks postoperative, compared to baseline (p = 0.194). A significant higher 6MWT was observed after prehabilitation and one year postoperative, compared to baseline (p=<0.001). The SPPB was significant higher at all timepoints. Overall 90-day complication rate was 25.8 %, readmission rate 6.3 % and mortality occurred in 2.1 %. Total costs were €518.50 per patient.

CONCLUSION

This is the first study of multimodal HBP by an app for CRC surgery patients with high compliance. Results show promising results regarding functional capacity and a low occurrence of complications, in line with multimodal supervised prehabilitation. This by reducing costs by half.

Home-based prehabilitation: a systematic review and meta-analysis of randomised trials

BACKGROUND

Prehabilitation aims to enhance preoperative functional capacity through exercise, nutrition, and psychological programs. Home-based prehabilitation represents an alternative to hospital prehabilitation, with the advantage of not utilising hospital resources. This review aims to evaluate adherence and clinical effectiveness of home-based prehabilitation.

METHODS

We searched PubMed, Cochrane, and Embase up to October 1, 2024 for randomised controlled trials comparing home-based prehabilitation with standard care. The primary outcome was the proportion of patients with postoperative complications. Secondary outcomes included protocol adherence, and 6-min walking test. We used risk ratios (RR) and mean differences to summarise the results. The risk of bias was assessed using RoB 2 tool.

RESULTS

We included 29 randomised trials for a total of 3508 patients. Median adherence to home-based prehabilitation programs was 82%. Home-based prehabilitation reduced the proportion of patients with postoperative complications (508/1322 [38.4%] vs 578/1335 [43.3%], risk ratio 0.84, 95% confidence interval [CI] 0.72-0.98, P=0.02, I2=44%, low certainty). After home-based prehabilitation, 6-min walking test performance was better compared with control (MD 28.2 m (95% CI 9.5-46.9; P<0.01, I2=48). Preoperative depression (MD -0.65, 95% CI -0.87 to -0.43; P<0.001, I2=0%), postoperative anxiety (MD -0.50, 95% CI -0.75 to -0.25; P<0.001, I2=0%, low certainty) and length of hospital stays (MD -0.32 days, 95% CI -0.61 to -0.03; P=0.03, I2=45%, low certainty) were lower with home-based prehabilitation.

CONCLUSIONS

Home-based prehabilitation reduced the proportion of patients with postoperative complications, but with low certainty of evidence. It also improved preoperative functional capacity, reduced hospital stays, depression and anxiety scores, with good adherence to the intervention.

Getting fit for hip and knee replacement: The Fit-Joints multimodal intervention for frail patients with osteoarthritis - a pilot randomized controlled trial

BACKGROUND

Older adults with frailty have high risk for poor postoperative outcomes.

OBJECTIVE

To evaluate the feasibility of a multimodal prehabilitation program in older adults with frailty awaiting hip or knee replacement.

DESIGN

Parallel two-arm randomized controlled pilot trial.

PARTICIPANTS AND SETTING

Community-dwelling older adults with frailty awaiting joint replacement aged ≥60 years recruited from the Musculoskeletal Central Intake and Assessment Centre (MSK CIAC), Ontario.

INTERVENTION

Exercise, protein and vitamin D supplements, and medication review.

MEASUREMENT

Feasibility was assessed based on predefined progression criteria for recruitment, retention, data completion and adherence to intervention components. Clinical outcomes including Oxford Knee and Hip Scores, frailty index, Short Physical Performance Battery and health-related quality of life were collected at baseline, 1-week preoperative, 6-weeks and 6-months postoperative and were evaluated using generalized linear mixed models for repeated measures.

RESULTS

A total of 69 participants were enrolled. Recruitment rate was 35 %. Participants' mean age was 74 (standard deviation (SD): 7.5); 51 % were prefrail and 36 % were frail. Participant retention was 81 %, and data completion was ≥80 %. Mean adherence to strength exercises was 4 days (95 % confidence interval (CI): 3-5 days/week), balance 3 days (95 % CI: 2-4 days/week), and flexibility 3 days (95 % CI: 3-4 days/week). Adherence to vitamin D intake was 82 % (95 % CI: 73-92 %), and medication review consultation completion was 86 % (95 % CI: 68-95 %). These outcomes met the target values for feasibility success. The Oxford Knee Score at 6-months postoperative 8.78 (95 % CI: 0.40-17.16) showed a clinically meaningful and statistically significant difference between treatment groups. There were also indications of clinically relevant changes for frailty and quality of life post-surgery.

CONCLUSION

This trial provides strong evidence of feasibility and indications of improvements in postoperative clinical outcomes. Challenges to implementation and adherence were identified that can inform modifications to study design for future trials.

Feasibility of a virtual multimodal prehabilitation intervention for patients with cancer undergoing surgery

BACKGROUND AND AIMS

Current prehabilitation programs are often limited by poor recruitment and attrition rates. Remote delivery of prehabilitation may reduce barriers to participation and maximize program retention. We aimed to assess the feasibility (uptake, retention, fidelity), preliminary effectiveness, and acceptability of delivering a technology-supported prehabilitation program remotely to oncologic surgical candidates.

METHODS

This was a one-arm pragmatic feasibility study aiming to follow patients for 4-6 weeks preoperatively and 8 weeks postoperatively. All patients received a home-based aerobic and resistance exercise program, with psychosocial counselling as needed. Those at risk of malnutrition received nutritional counselling and supplements to meet personalized energy and protein targets. Adherence was assessed using an exercise watch and a mobile application for dietary assessment. In addition, we assessed physical effects, with change in 6-min walking distance of 20m defined as clinically meaningful recovery, and post-operative complications. Acceptability was assessed using a convergence mixed-methods approach.

RESULTS

A total of 28 participants were included (median 69, IQR 9.5 years; 12/28, 43 % males). Rate of recruitment was 47 %, retention was 78 %, and attendance was 86-93 %. Participants walked an average of 8168 (SD: 4685) steps per day preoperatively and 6809 (SD: 4819) steps per day postoperatively. They consumed on average 21.6 kcal/kg of ideal body weight (IBW) and 1.1 g protein/kg IBW during the first week of the intervention. Participants demonstrated significant improvements in remote physical tests before surgery (arm strength: +9.7 [5.7, 13.6] repetitions in arm curl, p < 0.001; leg strength: +3.2 [1.4, 4.9] sit-to-stand repetitions in 30 s, p = 0.001; endurance: +19.4 [12.7, 26.1] repetitions in the 2-min step test, p < 0.001). The majority (16/22, 73 %) achieved clinically meaningful recovery at 8 weeks postoperatively. All participants attested to the acceptability of exercising with remote supervision.

CONCLUSION

A technology-assisted prehabilitation program delivered remotely is feasible and could lead to physical benefits for a surgical cancer population.

Multimodal prehabilitation to improve functional abilities and reduce the chronic inflammatory response of frail elderly patients with gastric cancer: A prospective cohort study

BACKGROUND

Population ageing and cancer burden are important global public health problems that pose unprecedented threats to health systems worldwide. Frailty is a common health problem among elderly patients with cancer. In recent years, the use of prehabilitation to improve frailty has received widespread attention. Few studies have addressed the specific physiologic effects of prehabilitation on patients undergoing surgery.

METHODS

Frail elderly patients (aged at least 65 years) who underwent elective primary surgery for gastric cancer between September 2022 and October 2023 were included in this single-centre prospective cohort study and were categorized into multimodal prehabilitation or ERAS standard care groups. Prehabilitation, including physical and respiratory training, nutritional support and psychosocial treatment, was provided at least two weeks before gastrectomy. The primary outcome was functional status. Secondary outcomes included changes in indices of lipid metabolism, oxidative stress and chronic inflammation.

RESULTS

Over a 13-month period, 137 participants were assessed for eligibility, and 110 patients (prehabilitation 55, ERAS 55) were analysed. Compared with the baseline, patients in the prehabilitation group exhibited increased physical capacity before the operation (mean 6-min walk test change +28 m; P < 0.001). After prehabilitation intervention, inflammation-related indicators (NLR, PLR, SII and CRP) improved, and proinflammatory cytokine production (IL-5, IL-6, IL-1β, IL-10 and TNF-α) decreased. After surgery, the increase in IL-6 was reduced in the prehabilitation group (P = 0.036). Moreover, prehabilitation was associated with alleviating oxidative stress as determined by the levels of MDA (P = 0.005).

CONCLUSION

Multimodal prehabilitation can play a beneficial role in improving functional abilities by reducing chronic inflammation, improving lipid metabolism, and attenuating oxidative stress.

Factors influencing exercise rehabilitation behavior in older patients with esophageal cancer: A qualitative study

Exercise rehabilitation programs have been proven to beneficially affect several health-related outcomes for cancer patients. However, adherence is important to achieve optimal effects. This study aimed to investigate the influencing factors of exercise rehabilitation behavior in older esophageal cancer patients participating in pre- and postoperative exercise rehabilitation programs in a hospital setting. A qualitative study with semistructured interviews was conducted based on the capability, opportunity, and motivation as determinants of behavior (COM-B) theoretical framework. Purposeful sampling was used (n = 16), and the interview data were analyzed following thematic analysis. The results revealed ten key themes: capability factors (physical discomfort, limited knowledge, and psychological burden), opportunity factors (grassroots medical and health services support, family support, peer support, and healthcare professionals support), and motivation factors (high exercise self-efficacy, awareness of benefits, and desire for normal life). Understanding these factors can help design more effective exercise rehabilitation programs in clinical practice.

Patient Education on Exercise Prehabilitation Among Patients Receiving Neoadjuvant Therapy for Cancer Surgery in China: A Mixed-Methods Study

Background/Objectives: Patients undergoing neoadjuvant therapy have ample time to engage in exercise prehabilitation. This study aimed to describe the current status, facilitators, and barriers of exercise prehabilitation among this population. Methods: This sequential explanatory mixed-methods evaluation was conducted at a general tertiary hospital in Beijing. It included a quantitative survey of patients who received neoadjuvant therapy before cancer surgery and qualitative semi-structured interviews with both patients and physicians. Thematic analysis was conducted using the Capability, Opportunity, and Motivation Behavior model. Results: A total of 269 patients participated in the survey, with a completion rate of 99.6%. Only 52.6% and 1.1% of patients met the standards for aerobic and muscle-strengthening activities, respectively. Fewer than 40% of patients reported learning about exercise prehabilitation from physicians. Patients' knowledge was associated with meeting aerobic activity standards after adjusting for confounders (Level 1: odds ratio [OR] of 2.06, 95% confidence interval [CI] of 1.02-4.22; Level 2: OR of 2.56, 95% CI of 1.25-5.36). In total, 28 participants were interviewed. Facilitators of patient education on exercise prehabilitation included the surgeon's ability to gain trust and patients' prior commitment to exercise. Barriers included physicians' lack of awareness of exercise benefits, insufficient knowledge or time for patient education, concerns about patients' exercise ability, lack of referrals to rehabilitation clinics, challenges in follow-up, conflicts with cultural beliefs, and inadequate insurance coverage. Conclusions: This study revealed a lack of physician-led patient education on exercise prehabilitation. Efforts are needed to enhance physician education, implement collaborative clinics, and provide remote supervision.

Evaluating a digital prehabilitation tool in patients with colorectal surgery: protocol for a multisite randomised controlled trial

INTRODUCTION

Colorectal cancer is a leading cause of cancer mortality in the USA and occurs most frequently in older adults. These patients are at increased risk of adverse outcomes following major cancer surgery. While prehabilitation has been shown to mitigate this risk, multiple barriers to implementation remain. Our team created a digital tool co-designed with older adults that employs an algorithm to assess patient-specific geriatric vulnerabilities and generate personalised prehabilitation programmes before surgery.

METHODS AND ANALYSIS

We have designed a multisite, unblinded randomised trial to be completed at three high-volume academic cancer centres located in California or Texas. Our study population is individuals aged 65 and older with planned colorectal cancer resection who are proficient in English and have home internet access. We aim to enroll 132 patients who will be randomised in a 2:1 ratio to receive the intervention (assistance from a home health coach and access to the web application (web app)) or control (usual care with written prehabilitation materials). Our primary outcome is patient engagement with prehabilitation activities.

ETHICS AND DISSEMINATION

A properly executed, written, informed consent will be obtained from each subject prior to entering the subject into the trial. Information will be given in both oral and written form, and subjects may withdraw at any time from the study without effect on their medical care. The protocol and consent form have been approved by the Institutional Review Board (IRB) of each participating centre. We anticipate publication of results in a peer-reviewed journal.

Effectiveness of exercise interventions on functional outcomes in frail adults with a previous or current diagnosis of cancer: a systematic review and meta-analysis

PURPOSE

Exercise improves functional outcomes in individuals with frailty and individuals with cancer, but it is unknown how exercise impacts function in individuals with both cancer and frailty. This systematic review aimed to determine if adults with cancer who are frail and participate in an exercise program have better functional outcomes compared to those who do not.

METHODS

Five databases (OVID Medline, Embase, CINAHL, EMCARE, and Ageline) were searched from inception to March 2024 for RCTs that investigated the impact of exercise on functional outcomes in individuals with cancer who are frail and ≥ 18 years. Title/abstract, full text review, and data extraction were done in duplicate. Cochrane ROB2 was used to assess risk of bias and GRADE for certainty of results.

RESULTS

Eleven RCTs with 1419 participants were included in this review. Meta-analysis did not find a significant difference between intervention and control groups for submaximal walking tests (95% CI 0.24 (- 0.05-0.53), Short Physical Performance Battery (95% CI - 0.50 (- 1.15-0.15)), and grip strength (95% CI 1.83 (- 0.75 to 4.41). However, positive trends emerged for those participating in exercise programs related to submaximal walking test, grip strength, sit to stand, SPPB, and TUG scores.

CONCLUSION

There are few RCTs investigating exercise in this population, with high heterogeneity of existing interventions. This leads to low certainty in the results of the current study.

IMPLICATIONS FOR CANCER SURVIVORSHIP

Cancer survivors and patients need to be screened for frailty and be engaged in appropriate exercise. Further work should be done investigating appropriate parameters of exercise interventions for this population.

INDEPSO-ISPSM consensus on peritoneal malignancies - Enhanced recovery after surgery in cytoreductive surgery (CRS) with/without hyperthermic intraperitoneal chemotherapy (HIPEC)

Background

The role of enhanced recovery after surgery (ERAS) in cytoreductive surgery and/or Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is evolving, with promising results that improve patient outcomes. This consensus exercise was carried out to address and standardize components of the ERAS protocol pertinent to the Indian context.

Method

The modified Delphi method was employed with two rounds of voting. All fifty invited specialists agreed to vote. There were 30 questions addressing the key elements of ERAS protocols. They were broadly distributed across four sections: Prehabilitation, Preoperative, Intraoperative, and Postoperative elements. A consensus was achieved if any one option received > 70 % votes (strong consensus > 90 %). If consensus was not achieved in round 1, the question was moved to round 2.

Results

After rounds I and II, 48/50 (95.8%) of invited panelists voted for the questions. The highest rate of 'skipped question' was 6% in both rounds. A consensus was obtained for 28/30 (93.33%) questions, and strong consensus was obtained for 5/30 (16.6%) questions. No consensus was obtained for two questions. Some of the panelists' recommendations contradicted the standard ERAS guidelines, such as using intraperitoneal drains in all patients and mechanical bowel preparation for left-sided colonic or rectal resections.

Conclusion

Despite some limitations, this consensus exercise represents a significant step toward advancement and pioneering efforts to improve patient outcomes by implementing and standardizing ERAS protocols in CRS and/or HIPEC tailored for India.

Prehabilitation Outcomes in Surgical Oncology Patients Undergoing Major Abdominal Surgery: A Meta-analysis of Randomized Control Trials

BACKGROUND

Prehabilitation has been increasingly utilized to optimize perioperative outcomes. In this study, we aim to evaluate the impact of uni- and multimodal prehabilitation on functional capacity and postoperative outcomes among surgical oncology patients undergoing major abdominal surgery.

PATIENTS AND METHODS

Three electronic databases (PubMed, Embase, Cochrane) were systematically searched up until December 2023. We included randomized controlled trials comparing prehabilitation to standard of care in surgical oncology patients undergoing major abdominal surgery. Our primary outcome was functional capacity as measured by the 6-min walk distance (6MWD). Secondary outcomes include postoperative complications, emergency readmissions, and length of stay (LOS). We stratified our findings to determine the impact of uni- versus multimodal prehabilitation on outcomes.

RESULTS

We included 27 studies with 2532 surgical oncology patients. Overall, patients undergoing prehabilitation demonstrated a significant improvement in preoperative functional capacity compared to those without prehabilitation (mean difference in 6MWD 28.32 meters [m], 95% CI 15.26, 41.39, p < 0.01). Prehabilitation was also associated with significantly lower odds of postoperative complications (odds ratio [OR] 0.60, 95% CI 0.46, 0.78, p < 0.01). There was no difference in emergency readmission (OR 0.90, 95% CI 0.59, 1.38, p = 0.61) or LOS (mean difference -0.42 days, 95% CI -1.01, 0.16, p = 0.15). Comparing uni- versus multimodal prehabilitation, multimodal prehabilitation was associated with greater improvements in functional capacity (6MWD 37.35 m versus 13.38 m) and lower odds of postoperative complications (OR 0.61, 95% CI 0.45, 0.82, p < 0.01 versus OR 0.63, 95% CI 0.36, 1.11, p = 0.10) CONCLUSION: Prehabilitation improves functional capacity and reduces postoperative complications among surgical oncology patients undergoing major abdominal surgery.

High-intensity interval training to improve cardiorespiratory fitness in a patient with frailty and multimorbidity: A case report

BACKGROUND

Low cardiorespiratory fitness predicts worse postoperative outcomes, exacerbated by age and frailty. Preoperative High-Intensity Interval Training (HIIT) improves cardiorespiratory fitness and postoperative outcomes but is challenging to implement in frailty due to perceived risks.

PURPOSE

The aim of this case report was to demonstrate feasibility of HIIT in a patient with frailty and multimorbidity.

CASE PRESENTATION

An 83-year-old frail male with atrial fibrillation and limited mobility presenting with locally advanced rectal cancer was assessed as unfit for major surgery unless his cardiorespiratory fitness improved. Initial cardiopulmonary exercise testing demonstrated low cardiorespiratory fitness (peak oxygen consumption (V ˙ O2peak) of 11.45 mL·min-1·kg-1). He subsequently underwent 15 supervised HIIT sessions targeting a Rating of Perceived Exertion ≥ 15.

OUTCOMES

The patient demonstrated initial substantial improvements in his physical condition, increasing maximal work rate from 27.5 W to 55 W. However, there was no additional progress following session eight. At his post-exercise CPET he rapidly fatigued, resulting in a V ˙ O2peak of 7.4 mL·min-1kg-1. Clinical investigations revealed a worsening anemia with a hemoglobin of 92 g/L caused by an undiagnosed synchronous cecal tumor which was corrected preoperatively. Postoperatively, the patient recovered without complications and was successfully discharged home.

CONCLUSION

Personalized HIIT improved exercise duration and work rate and was associated with positive postoperative outcomes in this patient with frailty and multimorbidity. A unique feature of this case was the unexpected loss of training progress and V ˙ O2peak deterioration post-HIIT, which prompted further clinical investigations. These identified a worsening anemia and resulted in important changes in both the preoperative and intraoperative treatment.

Proactive physical activity programs in lung cancer surgical patients at short and mid-term: A systematic review and meta-analysis

OBJECTIVE

To assess the effects of proactive physical activity (PA) programs on lung cancer patients undergoing lung resection at short and mid-term.

METHODS

We conducted a literature search through MEDLINE, Science Direct, Web of Science, and the Cochrane Library (last search October 2023). The GRADE System and the Cochrane tool were applied to quality assessment. The included studies focused on the application of proactive PA interventions among lung cancer surgical patients compared to usual or standard care. We performed a meta-analysis addressing hospital stay, cancer-related symptoms, quality of life, and exercise capacity at short and mid-term.

RESULTS

We selected 9 studies, which included 798 lung cancer patients. Proactive interventions were applied in combination with respiratory training and exercise in most of the studies. The treatment status was heterogeneous. Significant results in favour of proactive interventions were observed for hospital stay, cancer-related symptoms, quality of life, and short and mid-term exercise capacity.

CONCLUSIONS

Proactive PA interventions showed positive effects for reducing length stay, enhancing exercise capacity at short and mid-term, alleviating cancer-related symptoms, and improving the quality of life for lung cancer surgical patients.

PRACTICE IMPLICATIONS

Proactive interventions can optimize the timing and setting of PA results around lung surgical treatment.

Preoperative assessment of adults undergoing elective noncardiac surgery: Updated guidelines from the European Society of Anaesthesiology and Intensive Care

BACKGROUND

When considering whether a patient is fit for surgery, a comprehensive patient assessment represents the first step for an anaesthetist to evaluate the risks associated with the procedure and the patient's underlying diseases, and to optimise (whenever possible) the perioperative surgical journey. These guidelines from the European Society of Anaesthesiology and Intensive Care Medicine (ESAIC) update previous guidelines to provide new evidence on existing and emerging topics that consider the different aspects of the patient's surgical path.

DESIGN

A comprehensive literature review focused on organisation, clinical facets, optimisation and planning. The methodological quality of the studies included was evaluated using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) methodology. A Delphi process agreed on the wording of recommendations, and clinical practice statements (CPS) supported by minimal evidence. A draft version of the guidelines was published on the ESAIC website for 4 weeks, and the link was distributed to all ESAIC members, both individual and national, encompassing most European national anaesthesia societies. Feedback was gathered and incorporated into the guidelines accordingly. Following the finalisation of the draft, the Guidelines Committee and ESAIC Board officially approved the guidelines.

RESULTS

In the first phase of the guidelines update, 17 668 titles were initially identified. After removing duplicates and restricting the search period from 1 January 2018 to 3 May 2023, the number of titles was reduced to 16 774, which were then screened, yielding 414 abstracts. Among these, 267 relevant abstracts were identified from which 204 appropriate titles were selected for a comprehensive GRADE analysis. Additionally, the study considered 4 reviews, 16 meta-analyses, 9 previously published guidelines, 58 prospective cohort studies and 83 retrospective studies. The guideline provides 55 evidence-based recommendations that were voted on by a Delphi process, reaching a solid consensus (>90% agreement).

DISCUSSION

This update of the previous guidelines has covered new organisational and clinical aspects of the preoperative anaesthesia assessment to provide a more objective evaluation of patients with a high risk of postoperative complications requiring intensive care. Telemedicine and more predictive preoperative scores and biomarkers should guide the anaesthetist in selecting the appropriate preoperative blood tests, x-rays, and so forth for each patient, allowing the anaesthetist to assess the risks and suggest the most appropriate anaesthetic plan.

CONCLUSION

Each patient should have a tailored assessment of their fitness to undergo procedures requiring the involvement of an anaesthetist. The anaesthetist's role is essential in this phase to obtain a broad vision of the patient's clinical conditions, to coordinate care and to help the patient reach an informed decision.

The Potential for Lifestyle Intervention Among Patients Undergoing Transurethral Resection of Bladder Tumour Based on Patient Needs Including Smoking and Other Risky Lifestyle Factors: A Cross-Sectional Study

Bladder cancer is the tenth most common cancer worldwide, with non-muscle invasive bladder cancer (NMIBC) accounting for 75% of cases. Transurethral resection of bladder tumours (TURBT) is the standard treatment, but it is associated with significant risks of complications and recurrence. Risky lifestyle factors, including smoking, malnutrition, obesity, risky alcohol use, and physical inactivity (collectively termed SNAP factors), may worsen surgical outcomes and increase cancer recurrence. Prehabilitation programmes targeting these modifiable risk factors could improve patient outcomes. This cross-sectional study assessed 100 TURBT patients at a Danish university hospital to determine the prevalence of SNAP factors and the potential for lifestyle interventions. Data were collected via structured interviews, and intervention scenarios were projected based on efficacy rates of 5-100%. In total, 58% of patients had at least one risky SNAP factor, with smoking (29%) being the most prevalent, followed by physical inactivity (19%) and risky alcohol use (18%). Obesity (7%) and malnutrition (8%) were less common. Seventeen percent had multiple SNAP factors. No significant demographic indicators were associated with the presence of SNAP factors. TURBT patients with NMIBC show a high prevalence of risky lifestyle factors, including smoking and obesity, with over half affected. Systematic screening and targeted interventions could significantly improve patient outcomes and long-term health.

STRIVE pilot trial: a protocol for a multicentre pragmatic internal pilot randomised controlled trial of Structured TRaining to Improve fitness in a Virtual Environment (STRIVE) before surgery

INTRODUCTION

Home-based, virtually-supported care models may represent the most efficient and scalable approach to delivering prehabilitation services. However, virtual approaches to prehabilitation are understudied. This manuscript describes the protocol for an internal pilot randomised controlled trial of a virtually-delivered, multimodal prehabilitation intervention.

METHODS AND ANALYSIS

We will conduct a pragmatic, individual patient, internal pilot randomised controlled trial of home-based, virtually supported, multimodal prehabilitation compared with standard perioperative care in adults undergoing elective, inpatient thoracic, abdominal, pelvic and vascular surgery at five Canadian hospitals. Participants will be partially blinded; clinicians and outcome assessors will be fully blinded. The intervention consists of 3-12 weeks of a home-based, multimodal (exercise, nutrition and psychosocial support) prehabilitation programme supported through an online platform. The primary feasibility outcomes and their progression targets are (1) monthly recruitment of>6 participants at each centre, (2) intervention adherence of>75%, (3) retention of>90% of participants at the patient-reported primary outcome point of 30-days after surgery and (4) elicitation of patient, clinician and researcher-identified barriers to our pragmatic trial. A sample size of 144 participants will be adequate to estimate recruitment, adherence and retention rates with acceptable precision. All participants will be followed to either death or up to 1 year. As an internal pilot, if no substantive changes to the trial or intervention design are required, pilot participant outcome data will migrate, unanalysed by allocation, to the future full-scale trial.

ETHICS AND DISSEMINATION

Ethical approval has been granted by Clinical Trials Ontario (Project ID: 4479) and our ethics review board (Protocol Approval #20230399-01T). Results will be disseminated through presentations at scientific conferences, peer-reviewed publications, partner organisations and engagement of social and traditional media.

A scoping review of diet and exercise interventions for older cancer survivors' physical function

Lifestyle (diet and exercise) interventions across the cancer care continuum among younger cancer survivors (<60 years of age) demonstrate utility in improving physical function, and other cancer relevant health outcomes. However, the impact of lifestyle interventions on physical function in older (≥60 years) cancer survivors is not entirely clear. This scoping review aims to map and characterize the existing literature on the effect of diet and exercise interventions on physical function in older cancer survivors. Conducted to the JBI Manual for Evidence Synthesis and reported to the PRISMA guidelines, the literature search was performed on multiple databases through March 2024. A total of 19,901 articles were identified for screening with 49 articles published between 2006 and 2024 selected for full-text review. Of these, 36 studies included an exercise intervention, two focused on diet intervention, while 11 studies included both diet and exercise intervention. These 49 studies included various cancer types, cancer stages, and timepoints across the cancer care continuum. Most studies described physical function as their primary outcome and demonstrated maintenance or improvement in physical function. We identified several gaps in the current evidence including lack of (adequately powered) trials focused only on older cancer survivors, and trials focused on dietary interventions alone or dietary interventions combined with exercise interventions within this population vulnerable for nutritional inadequacies and declining physical function. Considering the growing population of older cancer survivors, this represents an important area for further research.

Home-based exercise prehabilitation to improve disease-free survival and return to intended oncologic treatment after cancer surgery in older adults with frailty: a secondary analysis of a randomized trial

BACKGROUND

Improving survivorship for patients with cancer and frailty is a priority. We aimed to estimate whether exercise prehabilitation improves disease-free survival and return to intended oncologic treatment for older adults with frailty undergoing cancer surgery.

METHODS

We conducted a secondary analysis of the oncologic outcomes of a randomized trial of patients ≥ 60 yr of age with frailty undergoing elective cancer surgery. Participants were randomized either to a supported, home-based exercise program plus nutritional guidance or to usual care. Outcomes for this analysis were one-year disease-free survival and return to intended oncologic treatment. We estimated complier average causal effects to account for intervention adherence.

RESULTS

We randomized 204 participants (102 per arm); 182 were included in our modified intention-to-treat population and, of these participants, 171/182 (94%) had complete one-year follow up. In the prehabilitation group, 18/94 (11%) died or experienced cancer recurrence, compared with 19/88 (11%) in the control group (hazard ratio [HR], 1.25; 95% confidence interval [CI], 0.66 to 2.34; P = 0.49). Return to intended oncologic treatment occurred in 24/94 (29%) patients the prehabilitation group vs 20/88 (23%) in the usual care group (HR, 1.53; 95% CI, 0.84 to 2.77; P = 0.16). Complier average causal effects directionally diverged for disease-free survival (HR, 0.91; 95% CI, 0.20 to 4.08; P = 0.90) and increased the point estimate for return to treatment (HR, 2.04; 95% CI, 0.52 to 7.97; P = 0.30), but in both cases the CIs included 1.

CONCLUSIONS

Randomization to home-based exercise prehabilitation did not lead to significantly better disease-free survival or earlier return to intended oncologic treatment in older adults with frailty undergoing cancer surgery. Our results could inform future trials powered for more plausible effect sizes, especially for the return to intended oncologic treatment outcome.

A digital, decentralized trial of exercise therapy in patients with cancer

We developed and evaluated the Digital Platform for Exercise (DPEx): a decentralized, patient-centric approach designed to enhance all aspects of clinical investigation of exercise therapy. DPEx integrated provision of a treadmill with telemedicine and remote biospecimen collection permitting all study procedures to be conducted in patient's homes. Linked health biodevices enabled high-resolution monitoring of lifestyle and physiological response. Here we describe the rationale and development of DPEx as well as feasibility evaluation in three different cohorts of patients with cancer: a phase 0a development study among three women with post-treatment primary breast cancer; a phase 0b proof-of-concept trial of neoadjuvant exercise therapy in 13 patients with untreated solid tumors; and a phase 1a level-finding trial of neoadjuvant exercise therapy in 53 men with localized prostate cancer. Collectively, our study demonstrates the utility of a fully digital, decentralized approach to conduct clinical trials of exercise therapy in a clinical population.

Efficacy of Prehabilitation in cancer patients: an Rcts systematic review with meta-analysis

BACKGROUND

Patients with cancer (PwC) who undergo specific treatments reported greater fatigue and reduced functional capacity as predominant outcomes, compromising their QoL during and following the treatment. Prehabilitation intervention, provided after diagnosis and before treatments, is to optimize the physiological reserve and address modifiable risk factors before surgery or chemotherapy to improve post-treatment results. The primary aim of this study is to obtain a common line of efficacy compared with prehabilitation treatment; the secondary endpoint is to assess the methodological quality of the studies eligible in the review.

METHODS

The systematic review was conducted from September to February 2024, in accordance with PRISMA guidelines. Databases consulted were MEDLINE, Scopus, Web of science and CINAHL, RCTs related to Prehabilitation intervention on PwC were included. The methodological quality of the included studies was assessed through the RoB2 Cochrane tool and the PEDro scale. Meta-analysis was performed to estimate relative treatment effects among evaluated outcomes.

RESULTS

Forty-two studies were included in the systematic review, 13 were included in the quantitative analysis. The results of the studies reporting reduced postoperative hospital stay, improved endurance, muscle strength, respiratory function, quality of life, and urinary incontinence. Critical analysis of the articles using the PEDro scale revealed 28 RCTs with a good rating, 9 with a fair rating, and 5 with a poor rating; in contrast, the Cochrane RoB2 tool revealed that all articles were at high risk of bias. Meta-analysis showed statistically significant values for 6MWT (38.53, 95%CI 33.03 - 44.04); HADS-depression (-0.71, 95%CI -0.93 -0.49) and HADS-anxiety (-0.49, 95%CI -0.76 -0.23).

CONCLUSIONS

Prehabilitation represents a specific intervention that aims to improve postoperative outcomes in fragile patients undergoing surgery, increasing their preoperative physiological reserve in anticipation of the stress they will face and facilitating the postoperative recovery of functional capacity. Prehabilitation is a good intervention to use, especially in terms of functional capacity and mental health, the latter being very impactful in terms of reduced levels of anxiety and depression. These data make it possible to justify supportive intervention by physical therapists aimed at improving and restoring health-related QoL especially in the short term.

Impact of exercise on cancer: mechanistic perspectives and new insights

This review critically evaluates the substantial role of exercise in enhancing cancer prevention, treatment, and patient quality of life. It conclusively demonstrates that regular physical activity not only reduces cancer risk but also significantly mitigates side effects of cancer therapies. The key findings include notable improvements in fatigue management, reduction of cachexia symptoms, and enhancement of cognitive functions. Importantly, the review elucidates the profound impact of exercise on tumor behavior, modulation of immune responses, and optimization of metabolic pathways, advocating for the integration of exercise into standard oncological care protocols. This refined abstract encourages further exploration and application of exercise as a pivotal element of cancer management.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Hospitalization-associated disability prediction using Hospital Frailty Risk Score in older patients undergoing pancreatectomy

PURPOSE

Frailty and hospitalization-associated disabilities (HAD) are geriatric conditions that should be managed in older patients undergoing pancreatectomy. The Hospital Frailty Risk Score (HFRS) can evaluate frailty based on medical records and could predict postoperative activities of daily living (ADL) decline. This study aimed to investigate whether HFRS affects the postoperative incidence of HAD in older patients who underwent pancreatectomy.

METHODS

This retrospective, observational study used data from a nationwide hospital-based database. We included consecutive patients aged ≥ 65 years who were diagnosed with pancreatic cancer (International Statistical Classification of Diseases, 10th revision code C25) and underwent curative pancreatectomy between April 2014 and August 2020. We evaluated preoperative frailty using HFRS. The primary outcome was HAD following pancreatectomy. Logistic regression analysis was performed for analyzing the impact of frailty on HAD following pancreatectomy.

RESULTS

We included 671 patients for the analysis (mean age 74.3 ± 5.6, male 54.8%). The prevalence of intermediate and high risk of frailty with HFRS ≥ 5 was 2.7%. The incidence of HAD was significantly higher in the intermediate- and high-risk groups compared to that in the low-risk group (33.3% vs. 8.4%, p < 0.001). Logistic regression analysis demonstrated that intermediate and high risks of frailty increased the likelihood of HAD (odds ratio, 3.55; 95% confidence interval: 1.12-11.2).

CONCLUSIONS

The risk of frailty evaluated using the HFRS increased the likelihood of developing HAD in older patients undergoing pancreatectomy. Future research on effective perioperative interventions for preventing postoperative HAD and enhancing postoperative ADL recovery is warranted.

Multimodal prehabilitation and postoperative outcomes in upper abdominal surgery: systematic review and meta-analysis

The impact of multimodal prehabilitation on postoperative complications in upper abdominal surgeries is understudied. This review analyzes randomized trials on multimodal prehabilitation with patient and hospital outcomes. MEDLINE, Embase, CINAHL, and Cochrane CENTRAL were searched for trials on prehabilitation before elective (non-emergency) abdominal surgery. Two reviewers independently screened studies, extracted data, and assessed study quality. Primary outcomes of interest were postoperative pulmonary complications (PPCs) and all-cause complications; secondary outcomes included hospital and intensive care length of stay. A meta-analysis with random-effect models was performed, and heterogeneity was evaluated with I-square and Cochran's Q test. Dichotomous variables were reported in log-odds ratio and continuous variables were presented as mean difference. Ten studies (total 1503 patients) were included. Odds of developing complications after prehabilitation were significantly lower compared to various control groups (- 0.38 [- 0.75- - 0.004], P = 0.048). Five studies described PPCs, and participants with prehabilitation had decreased odds of PPC (- 0.96 [- 1.38- - 0.54], P < 0.001). Prehabilitation did not significantly reduce length of stay, unless exercise was implemented; with exercise, hospital stay decreased significantly (- 0.91 [- 1.67- - 0.14], P = 0.02). Multimodal prehabilitation may decrease complications in upper abdominal surgery, but not necessarily length of stay; research should address heterogeneity in the literature.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

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

PURPOSE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

La préhabilitation, un nouveau parcours préopératoire pour améliorer la condition des patients

The maintenance and optimization of functional capacities before, during, and after treatment are major challenges for frailty persons as cancer's patients. It is now known that physical activity in prehabilitation plays a crucial role in limiting, among other things, post-operative complications. The benefits have already been demonstrated in various studies, including a decrease in hospitalization duration, an increase in cardiorespiratory endurance, improvement in quality of life, and better fatigue management. It is observed that patients who undergo prehabilitation are those who recover their preoperative capacities the fastest. However, it is estimated that only one-third of patients with access to prehabilitation improve their physical capacities.

Frailty: Implications for Neuroanesthesia

Frailty is increasingly prevalent in the aging neurosurgical population and is an important component of perioperative risk stratification and optimization to reduce complications. Frailty is measured using the phenotypic or deficit accumulation models, with simplified tools most commonly used in studies of neurosurgical patients. There are a limited number of frailty measurement tools that have been validated for individuals with neurological disease, and those that exist are mainly focused on spine pathology. Increasing frailty consistently predicts worse outcomes for patients across a range of neurosurgical procedures, including early complications, disability, non-home discharge, and mortality. Evidence for interventions to improve outcomes for frail neurosurgical patients is limited, and the role of bundled care pathways, prehabilitation, and multidisciplinary involvement requires further investigation. Surgery itself may be an intervention to improve frailty in selected patients, and future research should focus on identifying effective interventions to improve both short-term complications and long-term outcomes.

How much does it cost to be fit for operation? The economics of prehabilitation

PURPOSE OF REVIEW

Prehabilitation before elective surgery can include physical, nutritional, and psychological interventions or a combination of these to allow patients to return postoperatively to baseline status as soon as possible. The purpose of this review is to analyse the current date related to the cost-effectiveness of such programs.

RECENT FINDINGS

The current literature regarding the economics of prehabilitation is limited. However, such programs have been mainly associated with either a reduction in total healthcare related costs or no increase.

SUMMARY

Prehabilitation before elective surgery has been shown to minimize the periprocedural complications and optimization of short term follow up after surgical procedures. Recent studies included cost analysis, either based on hospital accounting data or on estimates costs. The healthcare cost was mainly reduced by shortening the number of hospitalization day. Other factors included length of ICU stay, place of the prehabilitation program (in-hospital vs. home-based) and compliance to the program.

[Prehabilitation through physical activity in oncology]

It has now been established that preoperative physical activity plays an essential role in minimizing postoperative complications. Patients who have undergone physical preparation recover their preoperative abilities more quickly. However, only about a third of those with access to such preparation report an improvement in their physical abilities. The modalities of intervention and follow-up, such as the training load and the generic format of the proposed sessions, seem to hinder patient participation in these programs, thus explaining the mixed results. In this context, it seems necessary to individualize prehabilitation in order to improve the functional capacities of people in this phase or in the phase of accelerated recovery after treatment or surgery.

Beyond the Consulting Room and Telemedicine: Unveiling the Future of Anesthesiology with Virtual Preoperative Assessment

Telemedicine has rapidly evolved, offering expanded applications including virtual consultations, remote patient education, and therapeutic options. It provides advantages such as increased accessibility, reduced travel time, and convenience. Challenges include privacy concerns, the digital divide, and the need for regulatory frameworks. Virtual preoperative assessment shows promise in safely identifying patients who do not require in-person consultations. Legal considerations and liability issues need to be addressed. While the COVID-19 pandemic has accelerated the adoption of telemedicine, it has also highlighted the need for comprehensive policies and equitable access to maximize its potential in health care delivery.

Impact of Dementia on the Postoperative Outcomes in Patients Undergoing Surgery for Head and Neck Cancers: A National Study

BACKGROUND

Dementia, a growing concern among the elderly, has an increased poor postoperative outcome that goes unrecognized by many. Our study aims to establish if dementia plays a role in the outcomes of head and neck cancer patients that undergo resections.

METHODS

We queried the National Inpatient Sample (NIS) database from 2016 to 2019 with a primary diagnosis of head and neck cancer who underwent surgical resection. Outcomes analyzed include postoperative delirium, ICU stay, complications, length of stay, and non-routine discharge.

RESULTS

A total of 77095 patients were included, of which 1140 patients had dementia. The mean age of the patients with dementia was 77.5 years (±9.1) versus 63.2 years (±12.1) with no dementia. Dementia patients had a higher non-home discharge rate (77.2% vs 46.8%, p = <0.001), extended length of stay (10.9 days ±14.7 vs 7.9 days ±8.8), postoperative delirium (15.4% vs 1.5%, p = <0.001), and longer ICU stay (8.3% vs 5.8%) as compared with patients with no dementia. A higher number of patients with Dementia were placed in long-term facilities (53.5% vs 14.6%) postoperatively. More dementia patients (7.9% vs 0.9%) were transferred in from another health care facility for surgery. Dementia was associated with higher odds of delirium (OR, 6.36; 95% CI, 5.2-7.77), non-routine discharge (OR, 2.05; 95% CI, 1.76-2.3), ventilation (OR, 0.8; 95% CI, 0.6-1.05), and length of stay (estimate 3.01, 95% CI, 1.84-4.184).

CONCLUSION

Preoperative dementia significantly impacts postoperative delirium, non-home discharge, and extended length of stay in head and neck cancer patients undergoing surgery.

The impact of prehabilitation on outcomes in frail and high-risk patients undergoing major abdominal surgery: A systematic review and meta-analysis

BACKGROUND & AIMS

Prehabilitation comprises multidisciplinary preoperative interventions including exercise, nutritional optimisation and psychological preparation aimed at improving surgical outcomes. The aim of this systematic review and meta-analysis was to determine the impact of prehabilitation on postoperative outcomes in frail and high-risk patients undergoing major abdominal surgery.

METHODS

Embase, Medline, CINAHAL and Cochrane databases were searched from January 2010 to January 2023 for randomised clinical trials (RCTs) and observational studies evaluating unimodal (exercise) or multimodal prehabilitation programmes. Meta-analysis was limited to length of stay (primary end point), severe postoperative complications (Clavien-Dindo Classification ≥ Grade 3) and the 6-minute walk test (6MWT). The analysis was performed using RevMan v5.4 software.

RESULTS

Sixteen studies (6 RCTs, 10 observational) reporting on 3339 patients (1468 prehabilitation group, 1871 control group) were included. The median (interquartile range) age was 74.0 (71.0-78.4) years. Multimodal prehabilitation was applied in fifteen studies and unimodal in one. Meta-analysis of nine studies showed a reduction in hospital length of stay (weighted mean difference -1.07 days, 95 % CI -1.60 to -0.53 days, P < 0.0001, I2 = 19 %). Ten studies addressed severe complications and a meta-analysis suggested a decline in occurrence by up to 44 % (odds ratio 0.56, 95 % CI 0.37 to 0.82, P < 0.004, I2 = 51 %). Four studies provided data on preoperative 6MWT. The pooled weighted mean difference was 40.1 m (95 % CI 32.7 to 47.6 m, P < 0.00001, I2 = 24 %), favouring prehabilitation.

CONCLUSION

Given the significant impact on shortening length of stay and reducing severe complications, prehabilitation should be encouraged in frail, older and high-risk adult patients undergoing major abdominal surgery.

Facilitators and barriers to the implementation of prehabilitation for frail patients into routine health care: a realist review

BACKGROUND

Despite evidence supporting the effectiveness of prehabilitation as a new preoperative care pathway to optimise perioperative outcomes, its implementation into routine health care is widely pending. Frail patients might particularly benefit from prehabilitation interventions, but facilitating and hindering factors need to be considered in the implementation process. Thus, our aim was to derive a programme theory on what prehabilitation programmes work for frail patients in what circumstances and why.

METHODS

Following Pawson's realist review approach, preliminary programme theories on facilitators and barriers were established. General and topic-specific databases were searched systematically for facilitators and barriers to the implementation of prehabilitation for frail patients. Articles were included if they dealt with multimodal prehabilitation programmes prior to surgery in a frail population and if they contained information on facilitators and barriers during the implementation process in the full text. Based on these articles, refined programme theories were generated.

RESULTS

From 2,609 unique titles, 34 were retained for the realist synthesis. Facilitating factors included the individualisation of prehabilitation programmes to meet the patients' needs and abilities, multimodality, adaption to the local setting and health care system, endorsement by an ambassador and sharing of responsibilities among a multidisciplinary team. Central barriers for frail patients were transportation, lack of social support, and inadequate, overwhelming information provision.

CONCLUSIONS

Implementing prehabilitation as a new care pathway for frail patients requires organisational readiness and adaptability to the local setting. On an individual level, a clear understanding of responsibilities and of the intervention's goal among patients and providers are necessary. Added attention must be paid to the individualisation to fit the needs and restrictions of frail patients. This makes prehabilitation a resource-intense, but promising intervention for frail surgery patients.

[Pre-rehabilitation of oncological patients before extensive abdominal and thoracic surgery: a literature review]

Surgery is one of the leading treatment methods of patients with primary or recurrent malignant neoplasms in the thoracic or abdominal cavity. Extensive abdominal interventions are accompanied by such adverse outcomes as blood loss, hypoxia, inflammation, blood clotting abnormality, emotional and cognitive disorders, that increases the incidence of serious complications and worsens the treatment outcome and life quality in weakened oncological patients. Multimodal pre-rehabilitation before surgery can significantly decrease the incidence and severity of postoperative complications. The rehabilitation complex includes exercise therapy, nutritional and psychological support, smoking cessation and pharmacotherapy. Currently, there are a number of questions facing rehabilitation specialists and oncologists, that are related to the determination of pre-rehabilitation optimal timing and process duration, the choice of specific physical exercises, determining the load intensity. This review presents a current view on understanding of surgical stress in extensive abdominal interventions, its effect on the oncological process course, summarizes the experience of last years in choosing pre-rehabilitation program taking into account pathogenetic mechanisms of surgical stress and individual patient's characteristics. Special attention is paid to the comparison of physical exercises' various types, their action mechanisms at different stages of pathological process, the issues of load dosing during pre-rehabilitation activities.

Effect of prehabilitation on postoperative outcomes in the frail older people: A systematic review and meta-analysis

OBJECTIVE

The study investigates the impact of preoperative rehabilitation on the surgical prognosis of frail older patients.

METHOD

The effect sizes of all studies retrieved and included by the nine databases were analyzed and expressed as RR and WMD.

RESULTS

8 studies with 902 participants met the criteria for inclusion. A significant reduction in total complications (RR = 0.84, 95 % CI = 0.73 to 0.97, P = 0.021) and the 6MWT after surgery (WMD = 74.76, 95 % CI = 44.75 to 104.77, P = 0.000) was observed in the prehabilitation group. But it had no differences in mortality(RR = 1.89, 95 % CI = 0.75 to 4.72, P = 0.176), readmission rates(RR = 1.04, 95 % CI = 0.56 to 1.91, P = 0.906) and LOS(WMD = -0.24, 95 % CI = -1.00 to 0.52, P = 0.540).

CONCLUSIONS

Prehabilitation had positive effect on postoperative complications and functional recovery in frail older patients.

A model to predict level of adherence to prehabilitation in older adults with frailty having cancer surgery

PURPOSE

Preoperative exercise could improve postoperative outcomes for people with frailty; however, little is known about how to predict older people's adherence to exercise before surgery (i.e., prehabilitation) programs. Our objective was to derive and validate a model to predict prehabilitation adherence in older adults living with frailty before cancer surgery.

METHODS

This was a nested prospective cohort study of older adults with frailty having cancer surgery who participated in a randomized controlled trial of home-based prehabilitation compared with standard perioperative care. We constructed a multivariable ordinary least squares linear regression model to predict adherence. Covariates were selected a priori based on clinical expertise and systematic review. Optimism was estimated through internal validation using bootstrap resampling.

RESULTS

The derivation cohort consisted of 95 participants in the intervention arm of the trial. Percent adherence ranged from 0% to 100%, with a mean (standard deviation) of 61 (34)%. Previous physical activity and age were the only predictors significant at the 5% level.

CONCLUSION

A prespecified multivariable model may help to explain a modest degree of variation in prehabilitation adherence in older people with frailty. While this model is an important step toward personalizing prehabilitation support, this study was limited by a small sample size and future research is needed to better understand personalized prediction of prehabilitation adherence in older people with frailty.

Digital health in geriatric oncology: A Young International Society of Geriatric Oncology review

The integration of digital health technologies in geriatric oncology has the potential to enhance patient care and self-management. This review article discusses the applications of these technologies, including teleassessment, telemonitoring, and teleintervention, within geriatric oncology, and evaluates their potential to improve cancer care and patient outcomes. We also review challenges to the implementation of digital health technologies among populations of older patients with cancer. The article provides a perspective for clinicians, researchers, policymakers, and patients on the integration and utilisation of digital health technologies in current geriatric oncology practice.

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.

Consumer Perspectives on the Adoption of a Prehabilitation Multimodal Online Program for Patients Undergoing Cancer Surgery

This study aimed to explore patients' perspectives on the adoption of a prehabilitation multimodal online program. Patients recovering from gastrointestinal cancer surgery at a tertiary hospital between October 2021 and November 2022 were invited to participate. An e-Health program including intensity exercises, nutrition and psychological counselling was used. Patients were instructed to navigate the e-Health program over 24 h using an iPad and then complete the study survey. Patients' characteristics, use of technology, views and minimal expected outcomes from a preoperative online program were collected. Of the 30 patients included, most were female, most reported confidence in the use of technology, most considered the online program safe and most agreed it would be beneficial for their health. "Poor preoperative health" and "lack of motivation and encouragement" were identified as the main barriers to the uptake of a preoperative online program, while program 'simplicity' and perceived 'benefits' were the main facilitators. Significant improvement in postoperative outcomes is perceived to influence patients' willingness to participate in a preoperative multimodal e-Health program. Gastrointestinal cancer patients perceived the adoption of a preoperative multimodal e-Health application as safe to be performed at home and of potential benefit to their health. A range of patient's characteristics, barriers and facilitators to the uptake of an online program were identified. These should be considered in future preoperative multimodal online programs to enhance patient experience, adherence and efficacy. The safety and efficacy of the online prehabilitation program will need to be determined in a larger randomized controlled trial.

Prehabilitation for general surgery: a systematic review of randomized controlled trials

BACKGROUND

Prehabilitation seeks to optimize patient health before surgery to improve outcomes. Randomized controlled trials (RCTs) have been conducted on prehabilitation, however an updated synthesis of this evidence is required across General Surgery to inform potential Supplementary discipline-level protocols. Accordingly, this systematic review of RCTs aimed to evaluate the use of prehabilitation interventions across the discipline of General Surgery.

METHODS

This study was registered with PROSPERO (CRD42023403289), and adhered to PRISMA 2020 and SWiM guidelines. PubMed/MEDLINE and Ovid Embase were searched to 4 March 2023 for RCTs evaluating prehabilitation interventions within the discipline of General Surgery. After data extraction, risk of bias was assessed using the Cochrane RoB 2 tool. Quantitative and qualitative data were synthesized and analysed. However, meta-analysis was precluded due to heterogeneity across included studies.

RESULTS

From 929 records, 36 RCTs of mostly low risk of bias were included. 17 (47.2%) were from Europe, and 14 (38.9%) North America. 30 (83.3%) investigated cancer populations. 31 (86.1%) investigated physical interventions, finding no significant difference in 16 (51.6%) and significant improvement in 14 (45.2%). Nine (25%) investigated psychological interventions: six (66.7%) found significant improvement, three (33.3%) found no significant difference. Five (13.9%) investigated nutritional interventions, finding no significant difference in three (60%), and significant improvement in two (40%).

CONCLUSIONS

Prehabilitation interventions showed mixed levels of effectiveness, and there is insufficient RCT evidence to suggest system-level delivery across General Surgery within standardized protocols. However, given potential benefits and non-inferiority to standard care, they should be considered on a case-by-case basis.

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

BACKGROUND

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

METHODS

Eligibility criteria: RCTs of unimodal or multimodal prehabilitation interventions.

SOURCES OF EVIDENCE

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

CHARTING METHODS

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

RESULTS

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

CONCLUSION

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

Frailty: the perioperative and anesthesia challenges of an emerging pandemic

Frailty is a complex and multisystem biological process characterized by reductions in physiological reserve. It is an increasingly common phenomena in the surgical population, and significantly impacts postoperative recovery. In this review, we will discuss the pathophysiology of frailty, as well as preoperative, intraoperative, and postoperative considerations for frailty care. We will also discuss the different models of postoperative care, including enhanced recovery pathways, as well as elective critical care admission. With discoveries of new effective interventions, and advances in healthcare information technology, optimized pathways could be developed to provide the best care possible that meets the challenges of perioperative frailty.
