Outcomes
Primary outcome [1] 306470 0
To Assess feasibility for a multicentered randomised control trial of two interventions for treatment of dry mouth in perioperative elective surgical patients as defined by the following:
Recruitment rate
Data completeness for pre-intervention and 30 min post intervention
Intervention acceptability
Protocol adherence- time from intervention to post-intervention assessment of 30 minutes
Timepoint [1] 306470 0
Study completion
Secondary outcome [1] 349061 0
To assess difference in mouth dryness before and after intervention; using a 100mm Visual Analogue Scale (VAS).
Absolute risk reduction in mouth dryness represented by rating of mouth dryness on a 5 point Likert scale post intervention (better or much better).
Timepoint [1] 349061 0
30 minutes after intervention

Efficacy
Statistical methods / analysis
Feasibility outcomes will be described with simple descriptive statistics.
Primary analysis will be by intention to treat rather than per protocol.
A sample size of 100 has been chosen as this should be sufficient to test feasibility outcomes.
Scientific aims will be tested using inferential statistics.
Continuous data will be analysed using a t-test with p values and confidence interval reported, A p value <0.05 will be taken as statistically significant. Patient self-rating of dry mouth as reported by VAS will be treated as continuous data. .
Ordinal data will be collected using a tick box scale. Statistical significance measures will be calculated using Chi-squared test. A p value <0.05 will be taken as significant.
