Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Following consent, subjects will be randomised to three timing regimes of 6% hypertonic saline (HS) inhalation over three days. Each day subjects will perform baseline spirometry, inhalation of bronchodilator, and inhalation of HS: either immediatly pre (not greater than 30 minutes pre), during (blocks of 10-15 breaths intersperced with airway clearance physiotherapy) or post (not greater than 30 minutes post) airway clearance physiotherapy in random order.
The three inhalation regimes will be carried out over three consecutive days (no washout) at the end of a hospital admission when clinical signs have stabilised. The timing regime for that day will be performed for each airway clearance physiotherapy session. Participants will perform their usual daily number of airway clearance sessions (1-3), the same number will be performed on each of the study days. Each HS inhalation will be 4mLs (usually 15-20 minutes to deliver). Each airway clearance physiotherapy session will be 20-40 minutes with the duration for that participant similar for the three days.

A post treatment spirometry will be performed two hours post baseline spirometry each day and a VAS completed regarding ease of expectoration, tolerability and overall satisfaction for this order of inhalation and aiway clearance. The spirometry readings will be recorded with the afternoon physiotherapy treatment. Thus the pre and post spirometry readings are two hours apart at a similar time of the day on each of the study days.

Outcomes

Lung function (FEV1, FVC) as measured by Spirometry
Timepoint [1] 266660 0
A post treatment spirometry will be performed two hours post baseline spirometry each day The spirometry readings will be recorded with the afternoon physiotherapy treatment. Thus the pre and post spirometry readings are two hours apart at a similar time of the day on each of the study days.
Primary outcome [2] 266661 0
Subjective efficacy, tolerability and overall satisfaction as measures on a VAS scale
Timepoint [2] 266661 0
Post treatment VAS scores will be performed two hours post baseline spirometry immediately prior to the post treatment spirometry each day The VAS readings will be recorded with the afternoon physiotherapy treatment. Thus the VAS readings are at a similar time of the day on each of the study days.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following consent, subjects will be randomised to three timing regimes of HS inhalation over three days (sequence of three interventions in sealed opaque envelopes). Each day subjects will perform baseline spirometry, inhalation of bronchodilator, and inhalation of HS (either pre, during or post airway clearance physiotherapy in random order).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An independent blinded researcher generated sequences of inhalation for before, during and after airway clearance for the anticipated 50 participants (power calculation) using a dice roll. The order of inhalations was then sealed in an opaque envelope prior to the studies commencement.
Masking / blinding
