Plain English summary of protocol
Background and study aims
More than 35,000 patients undergo cardiac surgery in UK every year. Around 10 – 40% of these patients suffer from post-operative complications. It is well known that patients with more health problems and those who are less active are more likely to have complications during and after surgery and may take longer to recover from their surgery.
An exercise programme carried out in the weeks leading up to surgery is called prehabilitation and exercise carried out after surgery is called rehabilitation.
The purpose of this trial is to find out if a prehabilitation programme carried out in the weeks leading up to heart surgery can improve fitness before surgery and if this results in better outcomes for patients after surgery.
Who can participate?
Patients aged over 18 listed for elective cardiac surgery at the James Cook University Hospital
What does the study involve?
Eligible patients will be asked to complete a number of physical assessments and questionnaires and will be put into 1 of 2 groups, Group 1 will be given an exercise programme to complete in the weeks leading up to their surgery. Group 2 will continue to receive standard care only and document any activity that they usually perform
What are the possible benefits and risks of participating?
There may be no direct benefit to taking part in this study. There is the potential that prehabilitation can improve patient fitness and outcomes from cardiac surgery. The results of this study may benefit the future care of patients undergoing heart surgery.
Where is the study run from?
The James Cook University Hospital

| Scientific title | Prehabilitation in elective patients undergoing cardiac surgery: a randomised controlled trial |
| Study acronym | PrEPS |
| Study objectives | Prehabilitation will improve pre-operative physical, functional and clinical outcomes in elective patients awaiting cardiac surgery |
| Ethics approval(s) | Approved 25/10/2019, Yorkshire & The Humber - Sheffield Research Ethics Committee (NHS Blood and Transplant Blood Donor Centre, Holland Drive, Newcastle upon Tyne, Tyne and Wear, NE2 4NQ, UK; +44 (0)207 104 8086; nrescommittee.yorkandhumber-sheffield@nhs.net), ref: 19/YH/0317 |
| Health condition(s) or problem(s) studied | Cardiac surgery |
| Intervention | Potentially eligible patients will be sequentially assigned a screening identification number irrespective of their participation in the trial and will be sent the participant information sheet (PIS) and a letter of invitation prior to attending their routine surgical clinic appointment. Patients expressing an interest in the trial will have the opportunity to ask questions and discuss the trial at this appointment. Eligibility will be confirmed by the consultant surgeon at the time of listing for Surgery by completing an eligibility checklist before seeking written informed consent A series of baseline assessments will be performed including the 6-minute walk test (6MWT), Maximal Inspiratory Pressure (MIP), quality of life questionnaires, Rockwood frailty score, handgrip strength, medical history, height, weight and demographics. Randomisation: Eligible patients will be randomised (allocated) to one of two groups and stratified by their baseline frailty scores. Half of the patients will receive prehabilitation and half will receive standard care only. Randomisation will be performed using a web-based system, managed by Newcastle Clinical Trials Unit which will be secure and prevent allocations being revealed until needed. Intervention group: Participants randomised to the prehabilitation group will be asked to attend hospital-based prehabilitation classes twice weekly for 4 weeks. An initial assessment will be carried out by a cardiac rehab physiotherapist at the first class. This assessment combined with the outcomes of the 6MWT will be used to develop a treatment programme tailored to the individual’s abilities. Participants will also be advised on a tailored exercise programme to carry out at home over the 4 week period. Participants will be provided with a patient diary and asked to document any form of exercise and duration that they carry out independently as well as during the prehabilitation sessions. Control group: Participants randomised to the standard care group will be asked to continue with the advice provided by the clinical team. Participants will be provided with a 4-week patient diary and asked to document any form of exercise and duration that they carry out independently. Assessments following intervention: All participants attend a routine pre-assessment clinic 1-2 weeks prior to surgery to assess fitness for surgery. Preassessment staff will be notified of the patient’s inclusion in the study. At this clinical appointment the research team will see the participant and complete the post-intervention assessments including the 6MWT, IMP, handgrip strength and patient-reported quality of life, HADS and satisfaction questionnaires. Patients will be asked about any adverse events that they have experienced from the time of randomisation. In the event that a patient is not seen by the research team at the time of this clinic, efforts will be made to obtain the study information once the patient has been admitted for surgery or a separate study visit if necessary. Patients will attend follow up visits at the hospital 6 weeks (routine care) and 12 weeks (study-specific) after their cardiac surgery to perform the 6MWT, MIP, handgrip strength, HADS and EQ5D5L. Patients will complete the following assessments: • 6MWT, MIP, handgrip strength, HADS and EQ5D5L at baseline, pre-operative assessment, 6 and 12 weeks post-op • Patient exercise diary between randomisation and day of surgery • Patient satisfaction questionnaire at the pre-operative assessment visit • Adverse events from point of randomisation until day of surgery All other information, including Euroscore II, complications (such as stroke), surgical outcomes, and data for longer-term follow-up over the full duration of the study, will be taken from medical records and other routinely collected data sources. The trial will be overseen by a Trial Oversight Committee that will contain independent members and members of the TMG. The Trial Management Group may be made up of the CI, NCTU co-investigators, statistician, Senior Trial Manager and the Trial Manager as required. |
| Intervention type | Other |
| Primary outcome measure | Change in exercise capacity measured by the 6-minute walk test (6MWT) from baseline to post-prehabilitation intervention (at 4-weeks and prior to surgery) |
| Secondary outcome measures | 1. Exercise capacity is measured using the 6-minute walk test at 6 and 12 weeks following the index surgery exercise capacity following surgery 2. Respiratory function is assessed using Maximal Inspiratory Pressure (MIP)at baseline, at the pre-surgical assessment, and at 6 and 12 weeks following the index surgery 3. Patient-reported quality of life is assessed using the EQ-5D-5L at baseline, at the pre-surgical assessment and at 6 and 12 weeks following the index surgery 4. Handgrip strength is assessed as a measure of frailty using a dynamometer at baseline, at the pre-surgical assessment and at 6 and 12 weeks following the index surgery 5. Anxiety and depression is assessed using the Hospital Anxiety and Depression Scale (HADS) at baseline, at the pre-surgical assessment and at 6 and 12 weeks following the index surgery 6. Surgical and post-operative data (including duration of operation, cardiopulmonary bypass times, time on ICU and discharge information) will be collected from participants’ medical notes and recorded on Case Report Forms (CRF) during their stay in hospital 7. Post-operative cardiac and pulmonary complications and hospital stay data will be collected, during the inpatient stay and at the 6 and 12 week follow up following the index surgery 8. Case Report Forms (CRF’s) will capture data regarding the adherence and delivery of the intervention components from baseline to the day of surgery. Deviations from the proposed intervention components and timescales will be documented 9. Screening logs will be used to collect recruitment rate data including; the number of patients who meet the eligibility criteria, reasons for exclusion and for patients choosing not to participate in the study 10. CRF’s will be used to capture the completion of research activity and protocol adherence at each of the data collection time points (baseline, pre-surgical assessment, point of surgery, 6 weeks and 12 weeks following the index surgery). Reasons for lack of attendance and withdrawal from study activity will be collected (added 13/10/2022) 11. Patient reported activity from randomisation until surgery using an activity diary. |
