Effects of Free Water Protocol on Inpatients in a Neurological Rehabilitation Setting
|ClinicalTrials.gov Identifier: NCT01209910|

Inpatients in the neurology rehabilitation units at Riverview Health Center― people who are brain-injured and or who have had a stroke ― often have dysphagia as a result of their condition. They are considered at high risk of aspiration, which can result in pneumonia. To limit that risk, these patients are only allowed to consume thickened liquids at the beginning of their rehabilitation. They are restricted from consuming thin liquids, which means they can't even drink water. Depending on the rate of their rehabilitation, these restrictions can last from six months to a year.
Patients on a diet of thickened liquids sometimes have difficulty consuming the required daily intake of fluids and they become dehydrated, which in turn can lead to other health complications. As well, thickened liquids do not always satisfy a patient's thirst, says Pooyania.
While Riverview does not allow inpatients with dyspagia to have water at the beginning of their rehabilitation, many rehab facilities in Canada and the U.S. follow the "Frazier Free Water Protocol," which does allow patients unrestricted water intake prior to and 30 minutes after meals. The belief that this protocol is safe is based on research done at the Frazier Rehabilitation Institute, where a study demonstrated no difference in rates of aspiration pneumonia between an experimental group on a free water protocol and a control group.
The Frazer study was only one randomized controlled trial with a very limited number of patients. There have been a few case reports as well, but at Riverview centre, the protocol is not accepted because the investigators don't believe there is enough evidence behind it. The investigators intend to provide more clinical evidence so that both the risks and benefits of a free water protocol can be assessed.
The investigators will be screening patients admitted to the neurology rehabilitation units at RCH, including both the stroke and acquired brain injury programs. The investigators expect to find at least 30 suitable candidates.
Participants will be educated about dysphagia and the free water protocol, and the treatment group will be allowed unrestricted water intake prior to and 30 minutes after meals. Individualized intervention to minimize aspiration will be provided. Daily and weekly monitoring and testing of all patients will take place. The pilot study will continue for 11 months. A secondary objective of the research is to determine the feasibility of expanding into a multi-centre clinical trial
