Prehabilitation has been postulated as an effective preventive intervention to reduce postoperative complications, particularly for elderly patients with a relatively high risk of complications. To date, it remains to be determined whether prehabilitation increases physical capacity and reduces postoperative complications. The aim of this study was to assess the feasibility of a 4-week multimodal prehabilitation program consisting of a personalized, supervised training program and nutritional intervention with daily fresh protein-rich food for colorectal cancer patients aged over 64 years prior to surgery. The primary outcome was the feasibility of this prehabilitation program defined as ≥80% compliance with the exercise training program and nutritional intervention. The secondary outcomes were the organizational feasibility and acceptability of the prehabilitation program. A compliance rate of ≥80% to both the exercise and nutritional intervention was accomplished by 6 patients (66.7%). Attendance of ≥80% at all 12 training sessions was achieved by 7 patients (77.8%); all patients (100%) attended ≥80% of the available training sessions. Overall, compliance with the training was 91.7%. Six patients (66.7%) accomplished compliance of ≥80% with the nutritional program. The median protein intake was 1.2 (g/kg/d). No adverse events occurred. This multimodal prehabilitation program was feasible for the majority of patients.

Purpose: Interest in prehabilitation, the preoperative enhancement of patients’ condition, is rising in the surgical field. Challenging factors appear to be patients’ motivation to participate in and their compliance with prehabilitation programs. The aim of this qualitative study was to study the real-life experience of prehabilitation by assessing the lived experience and perceptions of participants in a multimodal prehabilitation program and to explore factors that influence participation and compliance during prehabilitation. Methods: Patients who underwent surgery for colorectal cancer and who had participated in the 4-week multimodal prehabilitation program “BEFORE” feasibility study were recruited. Their lived experiences were collected through semi-structured, individual, in-depth interviews. Interviews were transcribed verbatim and analyzed using a thematical approach. As no new information emerged after the interviews, data were considered saturated. Results: Six patients were interviewed. Seven main themes were discussed during the interviews, including information provision, motivation for participation, and content of the program. The results of this study emphasize the importance of adequate patient education, in-hospital exercise with the supervision of physiotherapists, and a patient-centered program. Logistical problems and the impact of cancer diagnosis were most frequently reported as barriers to participation. Conclusion: Participation could be improved by providing adequate information and solving logistical issues. Patient-centeredness of the program is an important feature in improving adherence.

Background: Recent studies have demonstrated that accelerated enhanced recovery after colorectal surgery is feasible for specific patient populations. The accelerated enhanced recovery protocols (ERP) tend to vary, and the majority of studies included a small study population. This hampers defining the optimal protocol and establishing the potential benefits. This systematic review aimed to determine the effect of accelerated ERPs with intended discharge within one day after surgery. Methods: PubMed (MEDLINE), Embase, Cochrane and Web of Science databases were searched using the following search terms: colon cancer, colon surgery, accelerated recovery, fast track recovery, enhanced recovery after surgery. Clinical trials published between January 2005 – February 2023, written in English or Dutch comparing accelerated ERPs to Enhanced Recovery After Surgery (ERAS) care for adult patients undergoing elective laparoscopic or robotic surgery for colon cancer were eligible for inclusion. Results: Thirteen studies, including one RCT were included. Accelerated ERPs after colorectal surgery was possible as LOS was shorter; 14 h to 3.4 days, and complication rate varied from 0–35.7% and readmission rate was 0–17% in the accelerated ERP groups. Risk of bias was serious or critical in most of the included studies. Conclusions: Accelerated ERPs may not yet be considered the new standard of care as the current data is heterogenous, and data on important outcome measures is scarce. Nonetheless, the decreased LOS suggests that accelerated recovery is possible for selected patients. In addition, the complication and readmission rates were comparable to ERAS care, suggesting that accelerated recovery could be safe.

Background/Objectives: The preoperative improvement of patients’ functional capacity (prehabilitation) has gained attention in the surgical field, especially for colorectal cancer (CRC) patients. Despite the recognized benefits of prehabilitation programs, patients’ motivation to participate in and adhere to them remains a significant challenge. Several studies reported difficulties in recruiting participants and low adherence rates. This systematic review explored patients’ motivation for participation and adherence to prehabilitation programs for colorectal cancer surgery. Methods: A systematic search was conducted in the PubMed (MEDLINE), Embase, Cochrane, CINAHL, and Web of Science databases. Eligible studies included clinical trials published from inception until December 2024, written in English or Dutch, describing barriers and/or motivators affecting patient participation and adherence in prehabilitation programs. Results: A total of 89 studies, including 34 randomized controlled trials, were included. In total, 13,383 patients were included, with 7162 in the prehabilitation cohort. Participation rates ranged from 0 to 99.4%, and adherence rates ranged from 15% to 100%. Factors limiting participation included logistical issues and a busy schedule. Professional guidance, peer support, and regaining a sense of control improved adherence. Medical reasons, conflicting obligations, and intensive exercise limited adherence. Conclusions: This systematic review analyzed the current literature on participation and adherence in prehabilitation programs for colorectal cancer surgery patients. Overcoming logistical barriers and patient concerns through flexible, patient-centered approaches may improve participation and adherence. Future research should focus on large-scale randomized controlled trials, diverse healthcare settings, and strategies to enhance engagement with prehabilitation programs.

Previous studies showed that accelerated enhanced recovery programs (ERPs) with discharge 1–3 days after colorectal surgery are feasible for specific patients without compromising patients’ safety. This study aimed to examine the incidence, severity, and treatment of complications after treatment according to an accelerated ERP (CHASE). This accelerated ERP consisted of adjustments in pre-, peri- and postoperative care. Patients treated according to the CHASE protocol were compared to a retrospective cohort of patients who received standard ERAS care. The primary outcome was the rate of severe complications. The overall complication rates were similar in both cohorts (CHASE 30.7% vs ERAS 31.4%, p = 0.958) as well as severe complications (CHASE 20.9% vs ERAS 21.4%, p = 0.950). Among the 113 patients with a complicated course, the readmission rate was significantly higher in the CHASE cohort (41.9% vs 21.4%, p = 0.020). LOS after readmission was longer in the CHASE cohort (p = 0.018), but the total LOS was shorter (4 versus 6 days, p = 0.001). This study demonstrates that accelerated recovery can be safe for ASA I-II patients and has the potential to become a standard of care. Moreover, the CHASE protocol proved to be beneficial in terms of total LOS for patients with complications.
