Multimodal Prehabilitation for Surgery in the Elderly: a Randomised, Prospective, Multicenter, Multidisciplinary Trial
- Conditions
- Major SurgeryFrail Elderly Syndrome
- Interventions
- Procedure: Multimodal Prehabilitation
- Registration Number
- NCT04461301
- Lead Sponsor
- Insel Gruppe AG, University Hospital Bern
- Brief Summary
This multicentric, randomised controlled trial is to the investigators knowledge the first implementation of a multimodal, multidisciplinary prehabilitation approach using knowledge from different specialties to lower complications and to increase cost effectiveness after major surgery in elderly, frail patients.
- Detailed Description
Postoperative complications occur in up to 50% of patients and major surgery is associated with a 20 to 40% reduction in physiological and functional capacity. The elderly have surgery 4 times more often than the rest of the population, thus in the future a major proportion of patients presenting for surgery will be older than 65 years. Elderly patients have more postoperative complications, a longer convalescence and higher surgical morbidity and mortality. The number and severity of complications are closely related to preoperative functional capacity, nutritional state, psychological state, and smoking behavior. Another population most probably to benefit from such a program are cancer patients with decreased functional health after cancer treatment. Cancer prehabilitation affords an opportunity for the patient to improve functional status while waiting to begin treatment. This is a patient group expected to grow in the future.
This is a multicenter, multidisciplinary, 2 arms (standard, n=233 vs intervention i.e. prehabilitation, n=233), randomised controlled trial (RCT).
The prehabilitation program is composed of 4 elements: exercise training, nutritional intervention, correction of anaemia and smoking cessation.
This multicentric, randomised controlled trial is to the investigators knowledge the first implementation of a multimodal, multidisciplinary prehabilitation approach using knowledge from different specialties to lower complications and to increase cost effectiveness after major surgery in elderly, morbid patients.
The primary outcome is measured by the comprehensive complication index (CCI). Secondary outcomes are physical parameters measured by cardio-pulmonary exercise testing (CPET), grip strengh, Nutritional Risk Score (NRS). Further outcomes are amongst others smoking behavior, haemoglobin concentration, days at home at 30 days (DAH30) and quality of recovery 15 (QoR15).

Group Intervention Description Intervention Multimodal Prehabilitation Patients that meet the inclusion criteria will be randomised and scheduled for surgery at least 2 weeks after the diagnosis/decision to proceed to surgery. This timeframe allows the implementation of a minimal 2 weeks (up to 4 weeks) multidisciplinary prehabilitation program. Prehabilitation program is composed of 4 elements: exercise training, nutritional intervention, correction of anaemia and smoking cessation. An individual treatment strategy will be proposed to the patient by a multidisciplinary team consisting of surgeon, anesthesiologist, dietitian and physiotherapist.
- Primary Outcome Measures
Name Time Method Comprehensive Complication Index (CCI) 30 days after surgery The comprehensive complication index (value from 0 = no complication to 100 = death) is a valuable, validated index for the assessment of multiple postoperative complications. It has been developed based on Swiss hospital data and has been validated internationally.
- Secondary Outcome Measures
Name Time Method Cardiovascular & Pulmonary Before and after 2-4 weeks of prehabilitation, at 30 days Cardio-Pulmonary Exercise Test (CPET): Peak VO2, VO2 at VT1, peak VE, VE/VCO2 slope, O pulse, FEV1, FEV1/FVC, resting HR, HR reserve, resting systolic and diastolic BP, CPAx ICUD and CPAX HosD in case of ICU admission, Maximum inspiratory pressure , Grip strength, NTproBNP, serial hsTroponin in case of raised NTproBNP, change in preoperative P-POSSUM score
Nutrition & Bioimpendance At the beginning of study, before and after surgery, at 30 days. Nutritional Risk Score (NRS), Bio impedance: weight, muscle mass, fat mass, percent body fat, extracellular water/intracellular water, and phase angle, Fat Free Body Mass (FFM) and Lean body Mass (LBM), Days nil per mouth
Anaemia 30 days after surgery Presence of anaemia, Transfusion rates in the first 30 days after surgery.
Smoking At the beginning of study, before and after surgery, at 30 days. Successful smoking cessation rate, Exhaled CO measured.
Questionnaires for recovery, anxiety and cardiac risk At the beginning of study, before and after surgery, at 30 days. Quality of Recovery Score (QoR-15), State-Trait Anxiety Inventory Test (STAI-T), Duke Activity Status Index (DASI)
