Immediate knowledge increase from an oral cancer information leaflet in patients attending a primary health care facility: a randomised controlled trial.

The aim was to determine the immediate influence of a validated patient information leaflet (PIL) on oral cancer and knowledge in primary care attenders. Participants were patients (n=800) attending their primary health care provider from 14 general practices (eight dental and six medical) in the north west of England. Measures were a previously validated knowledge questionnaire (36 dichotomous items), self-reported dental service attendance history and demographic variables. The results showed that patients who had read the oral cancer PIL demonstrated a significant increase in knowledge regardless of clinical setting (F[1,739]=246.24, P<0.0001). Patients showed improvements in selecting the correct signs and risk factors associated with disease. Immediate knowledge gain from a simple PIL about oral cancer was found and independent of the primary care facility, where the PIL was distributed.
