Brief summary

Chronic heart failure is a progressive and burdensome syndrome with thirst as a major reason for non-compliance to self- care practices such as fluid restriction. Due to the life threatening effects of non- compliance to fluid restricted therapy, evidence based interventions are needed to manage thirst. Systematic evaluation of available strategies such as chewing gum is essential in ensuring that the best possible management is provided to CHF patients. The purpose of this study is to test the hypothesis that chewing gum can reduce thirst in people with chronic heart failure.

Interventions

The intervention involves the use of chewing gum (Xylitol, Epic Dental LLC peppermint flavour) to reduce thirst in patients with CHF. Consenting subjects will be randomised to each study arms. Study participants allocated to the chewing gum will be instructed to chew sugar free Xylitol, Epic Dental LLC peppermint flavour gum gently, for at least 10 minutes, six times a day and as desired throughout the day when the mouth feels dry or when they are thirsty.

The intervention involves the use of chewing gum (Xylitol, Epic Dental LLC peppermint flavour) to reduce thirst in patients with CHF. Consenting subjects will be randomised to each study arms. Study participants allocated to the chewing gum will be instructed to chew sugar free Xylitol, Epic Dental LLC peppermint flavour gum gently, for at least 10 minutes, six times a day and as desired throughout the day when the mouth feels dry or when they are thirsty. Participants in the no chewing gum group will instructed to continue with what they normally use to relieve their thirst. Participants will continue the use of chewing gum for 2 weeks as part of the study protocol. After the 2 week intervention if subjects perceive there has been benefit in the use of chewing gum and the patient wishes to continue using the gum, they are allowed to do so. Monitoring of adherence to the intervention is performed through self- reporting. At the end of the trial participants will be asked to report their adherence to the intervention and if they are continuing to use the chewing gum.
