Actionable Factors Fostering Health Value Generation and Scalability of Prehabilitation: A Prospective Cohort Study.

IMPORTANCE: Prehabilitation has potential for improving surgical outcomes as shown in previous randomized controlled trials. However, a marked efficacy-effectiveness gap is limiting its scalability. Comprehensive analyses of deployment of the intervention in real-life scenarios are required. OBJECTIVE: To assess health outcomes and cost of prehabilitation. DESIGN: Prospective cohort study with a control group built using propensity score-matching techniques. SETTING: Prehabilitation Unit in a tertiary-care university hospital. PARTICIPANTS: Candidates for major digestive, cardiac, thoracic, gynecologic, or urologic surgeries. INTERVENTION: Prehabilitation program, including supervised exercise training, promotion of physical activity, nutritional optimization, and psychological support. MAIN OUTCOMES AND MEASURES: The comprehensive complication index, hospital and intensive care unit length of stay, and hospital costs per patient until 30 days after surgery. Patients were classified by the degree of program completion and level of surgical aggression for sensitivity analysis. RESULTS: The analysis of the entire study group did not show differences in study outcomes between prehabilitation and control groups (n=328 each). The per-protocol analysis, including only patients completing the program (n=112, 34%), showed a reduction in mean hospital stay [9.9 (7.2) vs 12.8 (12.4) days; P =0.035]. Completers undergoing highly aggressive surgeries (n=60) additionally showed reduction in mean intensive care unit stay [2.3 (2.7) vs 3.8 (4.2) days; P =0.021] and generated mean cost savings per patient of €3092 (32% cost reduction) ( P =0.007). Five priority areas for action to enhance service efficiencies were identified. CONCLUSIONS AND RELEVANCE: The study indicates a low rate of completion of the intervention and identifies priority areas for re-design of service delivery to enhance the effectiveness of prehabilitation.

Repeatability and learning effect in the 6MWT in preoperative cancer patients undergoing a prehabilitation program.

OBJECTIVE: The main objective was to assess repeatability and learning effect of the 6-min walk test (6MWT) in a cohort of preoperative cancer patients referred to a prehabilitation program. As a secondary objective, we aimed to identify determinants of improvement in the second test. MATERIALS AND METHODS: Secondary analysis from a large prospective study on the implementation of a multimodal prehabilitation program in a real-life scenario. Eligible patients were assessed at baseline before starting the prehabilitation program. The 6MWT was conducted according to the American Thoracic Society (ATS)/European Respiratory Society (ERS) guidelines with two tests being performed under identical conditions separated by 30 min. The distance covered (in meters) and the physiological responses (heart rate, oxygen saturation, fatigue, and dyspnea) to each test were recorded and compared. RESULTS: A total of 170 patients (60.9%) were analyzed. Repeatability of the distance covered with the 6MWT was excellent (ICC = 0.98; 95% CI: 0.92-0.99), but a mean increase of + 19.5 m (95% CI: 15.6-23.5 m; p = < .001) in the second test was found, showing a learning effect with limits of agreement between - 31.3 and 70.4 m. Coefficient of variation was 4%. No clinical factor was found to be associated with an improvement in the second test. CONCLUSIONS: The 6MWT showed excellent repeatability in preoperative cancer patients, but a significant learning effect is present. No associated factors with a clinically meaningful improvement in the second test were identified. In light of these findings, two attempts of the 6MWT should be encouraged in this population.

Association between the 6MWT and other measurements of physical functioning in patients with cancer awaiting major surgery.

BACKGROUND: The Six Minute Walk Test (6MWT) is a widely used measure of functional capacity in (p)rehabilitation of cancer patients, but it is time-consuming and requires specific space conditions. In this study we explore the association between the 6MWT with other measurements of physical functioning and their predictive value in classifying patients according to their estimated functional capacity. DESIGN: This prospective study included cancer patients referred to a prehabilitation programme prior to major surgery. For each patient, data on different measurements of physical functioning including the Duke Activity Status Index (DASI), the handgrip strength, the 30" Sit-to-Stand Test and self-reported physical activity levels were collected. Bivariate associations were performed to determine the association between the 6MWT and other variables. Multivariate analyses were performed to identify potential predictive factors of 6MWT in this population. A subsequent algorithm was developed to classify patients based on their functional capacity (good performance - 6MWT>400 m or poor performance 6MWT<400 m) RESULTS: Between mid-2018 to mid 2022, 692 patients were assessed of whom the 6MWT was performed in 524 (75.7 %) (mean age 72.5 ± 11.8 years; 57.1 % men). Moderate-to-strong correlations were found between 6MWT and 30" Sit-To-Stand Test (r = 0.54, p < 0.001), DASI (r = 0.68; p < 0.001) and handgrip strength (r = 0.5; p < 0.001). Multivariate analyses confirmed that a combination of six variables were able to classify 80 % of patients in good (>400 m) or poor (<400 m) performance in the 6MWT. CONCLUSION: The 6MWT was moderately associated with several variables of physical functioning, a combination of which can be used to predict performance in the 6MWT.

Perioperative Nursing as the Guiding Thread of a Prehabilitation Program.

Multimodal preoperative prehabilitation has been shown to be effective in improving the functional capacity of cancer patients, reducing postoperative complications and the length of hospital and ICU stay after surgery. The availability of prehabilitation units that gather all the professionals involved in patient care facilitates the development of integrated and patient-centered multimodal prehabilitation programs, as well as patient adherence. This article describes the process of creating a prehabilitation unit in our center and the role of perioperative nursing. Initially, the project was launched with the performance of a research study on prehabilitation for gastrointestinal cancer surgery. The results of this study encouraged us to continue the implementation of the unit. Progressively, multimodal prehabilitation programs focusing on each type of patient and surgery were developed. Currently, our prehabilitation unit is a care unit that has its own gym, which allows supervised training of cancer patients prior to surgery. Likewise, the evolution of perioperative nursing in the unit is described: from collaboration and assistance in the integral evaluation of the patient at the beginning to current work as a case manager; a task that has proven extremely important for the comprehensive and continuous care of the patient.

Role of Co-creation for Large-Scale Sustainable Adoption of Digitally Supported Integrated Care: Prehabilitation as Use Case.

Introduction: The efficacy-effectiveness gap constitutes a well-known limitation for adoption of digitally enabled integrated care services. The current report describes the co-creation process undertaken (2016-2021) to deploy a prehabilitation service at Hospital Clínic de Barcelona with the final aim of achieving sustainable adoption and facilitate site transferability. Methods: An implementation research approach with a population-based orientation, combining experience-based co-design and quality improvement methodologies, was applied. We undertook several design-thinking sessions (Oct-Nov 2017, June 2021 and December 2021) to generate and follow-up a work plan fostering service scalability. The implementation process was assessed using the Comprehensive Framework for Implementation Research, leading to the identification of key performance indicators. Discussion: Personalization and modularity of the intervention according to patients' surgical risk were identified as core traits to enhance patients' adherence and value generation. A digitally enabled service workflow, with an adaptive and collaborative case management approach, should combine face-to-face and remotely supervised sessions with intelligent systems for patients' and professionals' decision support. The business model envisages operational costs financed by savings generated by the service. Conclusions: Evidence-based co-creation, combining appropriate methodologies and a structured evaluation framework, was key to address challenges associated with sustainable prehabilitation service adoption, scalability and transferability.

Multimodal prehabilitation as strategy for reduction of postoperative complications after cardiac surgery: a randomised controlled trial protocol.

INTRODUCTION: Prehabilitation programmes that combine exercise training, nutritional support and emotional reinforcement (multimodal prehabilitation) have demonstrated efficacy reducing postoperative complications in the context of abdominal surgery. However, such programmes have seldom been studied in cardiac surgery, one of the surgeries associated with higher postoperative morbidity and mortality. This trial will assess the feasibility and efficacy in terms of reduction of postoperative complications and cost-effectiveness of a multimodal prehabilitation programme comparing to the standard of care in cardiac surgical patients. METHODS AND ANALYSIS: This is a single-centre, randomised, open-label, controlled trial with a 1:1 ratio. Consecutive 160 elective valve replacement and/or coronary revascularisation surgical patients will be randomised to either standard of care or 4-6 weeks of multimodal prehabilitation that will consist in (1) two times/week supervised endurance and strength exercise training sessions, (2) promotion of physical activity and healthy lifestyle, (3) respiratory physiotherapy, (4) nutrition counselling and supplementation if needed, and (5) weekly mindfulness sessions. Baseline, preoperative and 3-month postoperative data will be collected by an independent blinded evaluator. The primary outcome of this study will be the incidence of postoperative complications. ETHICS AND DISSEMINATION: This study has been approved by the Ethics Committee of Clinical investigation of Hospital Clinic de Barcelona (HCB/2017/0708). The results will be disseminated in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT03466606.
