Research summary
The dietary management of chronic kidney disease patients is considered complex due to the impact of socio-economic, cultural factors or presence of other co-morbidities on their nutritional intakes. Dietary manipulation is usually required to manage high serum levels of potassium or phosphate, however by default this may result in reducing dietary protein intake. Having an inadequate protein intake may lead to malnutrition resulting in poorer patient healthcare outcomes. To achieve successful patient outcomes the renal dietitian is required to design an effective intervention on the basis of an accurate assessment of protein intake.
Guidelines recommend dietary assessment methods be used in practice. However, in the USA surveys have shown that these recommendations are not followed due to time constraints and the additional responsibility placed on clinicians, bringing into question the accuracy of dietary assessment.The aim of this study is to compare the total protein intake of haemodialysis patients using different dietary assessment methods.
Key objectives:
1. To compare different dietary assessment methods used to assess the total protein intake of a haemodialysis patient.
2. Ascertain the intra-rater reliability of each dietitian when assessing the total protein intake of a haemodialysis patient.
3. To explore the impact of known confounding factors relating to under-reporting on dietary assessment.This cross- sectional study involves adult patients attending a hospital based haemodialysis unit during the daytime. The patients are required to be literate.
Data collection will occur over 6 weeks.
Each patient will be required to complete a 4 day food diary in their own home. They will also receive a dietary assessment from the dietitian during a routine dialysis treatment for 20 minutes.The outcome of the study will be used to inform renal dietetic practice.
