Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1: oral nutritional supplement in a liquid form (i.e. a drink) providing 19g protein and 1.1 kJ of energy.
Arm 2: oral nutritional supplement in a solid form (i.e. a snack bar) providing 19g protein and 1.1 kJ of energy.

Each supplement will be consumed once per day (i.e one drink or one bar) for 8 weeks.
Intervention code [1] 284077 0
Treatment: Other
Comparator / control treatment
There is no control group. This is a within subject cross-over trial and results will be compared to the pre-supplementation period (i.e looking at a change from baseline). Each participant will move from arm 1 to arm 2, and vice versa, thus having both forms of the supplement. There will be no washout between the cross over. This is because the aims of the project are to assess nutritional supplementation for 16 weeks (independent of supplement type) and to also assess participant preference for each supplement type, which does not require a washout period.

Baseline, week 8 and week 16
Primary outcome [2] 286330 0
Nutritional status will be measured using the Patient Generated Subjective Global Assessment (PG-SGA) tool. This tool widely used in standard dietetic practice and has been shown to have favorable clinometric properties when used in the renal population.
Timepoint [2] 286330 0
Baseline, week 16
Primary outcome [3] 286331 0
Nutritional biochemical indices: serum albumin, transthyretin, urea and CRP will be recorded.
Timepoint [3] 286331 0
Baseline, week 8 and week 16
Secondary outcome [1] 295614 0
Participant preference of supplement type.

Acceptance of the supplement will be measured using an unstructured line scale. The unstructured line scale is 100 mm in length, and is anchored with 'dislike extremely' and 'like extremely' on opposing ends of the scale.

At the completion of the study participants will be asked to choose their preferred supplement (drink or snack bar) using a questionnaire that includes an option to select a tied category.

Health-related quality of life. Two quality of life indices will be used, a disease specific (KDHRQOL) and a generic instrument (EQ-5D)

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All eligible peritoneal patients will be invited to participate in the trial. Those consenting will be randomized to receive the liquid supplement followed by the solid supplement or the solid supplement followed by the liquid supplement. Allocation concealment will occur by using opaque, consecutively numbered, sealed envelopes with the group allocation written on a piece of paper inside.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation sequence will be constructed using simple randomization determined using a computer program.
Masking / blinding
Open (masking not used)
