Research summary
The aim of this study is to identify and understand the factors that might influence dietary behaviour and/or behaviour change in adult patients on long-term haemodialysis (HD).
To achieve this, participants will be interviewed to answer the central question of:
“What factors influence adherence and/or non-adherence to a low phosphate diet in adults on long-term HD?Dietitians working in the NHS educate HD patients on how to follow a low phosphate diet (LPD) in order to improve their blood phosphate level and thus manage the risk of bone disease.
However, patient adherence to a LPD is difficult to achieve and maintain. In order to change a patient’s behaviour, there needs to be an understanding of the factors that have most likely influenced the behaviour in question (Michie et al, 2008).
Current literature is deficient in understanding this problem as there are no studies which have explored the factors that might influence adherence and/or non-adherence to a LPD in HD patients. Therefore, this study will address a gap in knowledge.
The results of this study will also generate an evidence base to inform recommendations that will help Renal Dietitians develop appropriate and effective dietary interventions to help ensure greater adherence to a LPD, for the management of hyperphosphataemia.
Participants will be sampled from the relevant/identified haemodialysis units. Semi-structured interviews with 10-13 HD patients will be conducted, whilst they are on HD or in a separate room before/after their HD session. Each participant will have one, individual, face to face interview, which will last up to 60 minutes. A topic guide based on the Theoretical Domains Framework (Michie et al, 2012) will be used and interviews will be audio-recorded for transcription.
Participants will be under the care of the Renal Dietitians (except the PI) at Guys’ and St Thomas’ NHS Foundation Trust.REC name
