Knowledge of oral cancer, distress and screening intentions: longer term effects of a patient information leaflet.

Study aim was to determine the influence of a patient information leaflet (PIL) on mouth cancer to improve knowledge, reduce distress and increase intention to accept a mouth screen over a 2-month period. The design was a randomised controlled trial. Two dental practices in the northwest of England participated. Standardised multi-item scales of the three outcome measures were employed. The PIL was given to a randomised intervention group of patients in waiting room. Single sheet questionnaire was completed by both groups of patients at baseline in waiting room (immediately following leaflet administration in intervention arm of study). Repeat questionnaire completion at 8 weeks by all patients through postal system. Mann-Whitney U-tests comparing outcome variables between patients with and without access to the leaflet at baseline and 8 weeks were performed. Multiple logistic regression was used to predict re-reading of the leaflet at home. Useable replies were received from 317 patients (60% response rate). All measures showed some benefit of immediate exposure to the leaflet at follow up. Older patients, less initial knowledge, and self-reported smoking positively predicted the re-reading of the leaflet. The introduction of a mouth cancer PIL into dental practice may help to inform patients about oral cancer, moderate distress and encourage acceptance of an oral health screen.
