Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Managing swallowing in stroke patients - free water versus thickened fluids
Scientific title
In stroke patients who aspirate thin liquids does a free water protocol increase fluid intake and improve hydration status without increasing the risk of pneumonia when compared to the provision of thickened fluids only ?

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Free Water Protocol.
Allowing aspirating patients access to water between meals but not with food or drink. They also have access to thickened fluids at their bedside and at mealtimes and can choose whether they drink thickened fluids or water. Patients will remain on this protocol until they are assessed as no longer aspirating. The protocol includes a strict oral hygiene regime of twice daily teeth brushing and rinsing mouth after all food..
Intervention code [1] 256971 0
Treatment: Other
Comparator / control treatment
Thickened fluids.
Providing fluids thickened to the consistency which prevents aspiration. Thickened fluids are provided at bedside and at all mealtimes. Patients will remain on thickened fluids until they are assessed as no longer aspirating. They will also undergo the same oral hygiene regime as the intervention group.
Control group
Active

Outcomes
Primary outcome [1] 258944 0
Average daily fluid intake measured in mls.
This will be recorded by nursing staff on a fluid balance chart which records fluid offered and fluid drunk.
Water and thickened fluids drunk will be totalled separately.
Timepoint [1] 258944 0
Measured daily until patient is assessed as no longer aspirating or is discharged from hospital, whichever comes first.
Primary outcome [2] 258945 0
Incidence of pneumonia as diagnosed by medical officer and confirmed by chest Xray
Timepoint [2] 258945 0
Chest monitored clinically on a daily basis until patient is assessed as longer aspirating and chest Xray ordered as required
Primary outcome [3] 258946 0
Hydration status measured by urea to creatinine ratio from biochemical analysis of a blood sample
Timepoint [3] 258946 0
Blood sample taken on a weekly basis until patient is assessed as no longer aspirating or until patient is discharged whichever comes first.
Secondary outcome [1] 265112 0
Patient satisfaction with treatment measured by a simple 5 point Likert scale rating factors such as taste, feel in the mouth, thirst, and coughing
Timepoint [1] 265112 0
Surveyed on a weekly basis until patient is assessed as no longer aspirating or until patient is discharged whichever comes first
Secondary outcome [2] 265113 0
Time to resolution of dysphagia measured in days
Timepoint [2] 265113 0
calculated when no longer aspirating

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Researchers at hospital site will log on to the website, enter the details of the consented patient and be allocated a treatment group for their patient.
The patient's identifying number and hospital and their group allocation will be automatically sent to the chief researcher for the centralised patient data base.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
simple computerised sequence generation
Masking / blinding
Blinded (masking used)
