Summary

There is a well established link between physical inactivity and increased mortality in the general population and across many of the more common disease areas including chronic kidney disease (CKD). Patients with CKD have very high levels of morbidity and mortality and are known to have low fitness levels. Randomised controlled trials of exercise have demonstrated the benefits of physical activity for CKD patients. Despite this, physical activity levels remain low and translating these research findings into clinical practice is challenging. This feasibility study aims to assess the feasibility and acceptability of an instructor led structured exercise programme which includes an educational component to engage and increase physical activity levels in haemodialysis patients attending the Oxford University Hospitals Trust haemodialysis unit. Consented participants will fill in a self reported physical activity questionnaire (Human Activity Profile), partake in functional mobility assessments including (Timed-Up and Go) and a chair based exercise programme. At the end of the study, participants, and nursing staff will undertake a semi-structured interview aimed at understanding acceptability of the intervention. The results of this feasibility study will then be used to inform whether a larger trial in haemodialysis patients is feasible. All questionnaires, physical activity interventions and interviews will be undertaken during routine visits to the haemodialysis unit.

Detailed description

There is a well established link between physical inactivity and increased mortality in the general population and patients with chronic kidney disease (CKD) have low fitness levels when compared to their healthy counterparts (50% of expected norm when commencing dialysis therapy). Trials have shown that physical activity confers many physical and mental health benefits in this patient population, with improvements in fitness, walking capacity, health of the heart and quality of life; indeed, national guidelines now consider physical activity to be a cornerstone of disease management (Cochrane Collaboration 2006; Workgroup KD 2005). CKD patients have lower levels of physical activity than age-matched controls; this is particularly marked for older patients and those on dialysis. The Department of Health recommends ≥150 mins/ week of moderate intensity PA (accumulated in bouts of at least 10 minutes) for the general population (DoH UK Physical Activity Guidelines 2011). Many studies have sought to characterise the most effective forms of exercise for CKD patients. Recent attention has focussed on intradialytic cycling, with studies showing benefits not only for fitness and endurance but also muscle strength, power, and physical function. However, translating research guided physical activity programmes into routine clinical practice is challenging, requiring consideration of patients' physical and psychological barriers to exercise. Assessing the impact of any activity programme requires comparison of health and exercise behaviours pre and post intervention. Several self-report physical activity questionnaires are available but the Human Activity Profile has been validated in CKD patients (Johansen et al. 2001). However, information obtained from patient self-reporting is subjective and prone to bias. Objective measurement devices such as accelerometers are more accurate. Feasibility of an effective intervention to increase physical activity requires understanding of perceptions of exercise in the population of interest. In this way, the intervention can be specifically targeted to take account of perceived benefits and barriers towards physical activity and thereby increase compliance. This study will provide: 1)feasibility and acceptability of an instructor led chair based exercise programme and educational package (booklet); 2) both self-report and objective measurements of physical activity levels in a sample of haemodialysis patients. This key information will later be used to assess whether a informed large scale PA intervention study in haemodialysis patients is feasible.

Conditions

• End Stage Renal Failure on Dialysis

Interventions

Type	Name	Description
OTHER	Chair based exercises in the dialysis environment	Each participant will be given an educational / information booklet. It will include when the right time to engage in Physical Activity. The Chair-based Exercise Program will be the focus of the exercise intervention with written step- by-step instructions with demonstrative image of the exercises. Further details included in this booklet will include, information regarding the benefits of exercise including walking and safety measures in undertaking the exercises. Sports Exercise Instructor led Chair-based Exercise Programme Patients will be given Sports Exercise Instructor led training on how to perform the chair-based exercises, for 6 weeks. This will be delivered during one of the patients' dialysis sessions. The Instructor will deliver a short 10 minute session to patients and deliver safety instruction. Motivational interviewing Motivational interviewing will consist of discussion to encourage the participant without coercion and help them develop goals.
