Abstract:
OBJECTIVE:To investigate the effect of immediate feedback from a point of care test for salivary nicotine metabolites in promoting smoking cessation and reduction in tobacco use. DESIGN:Prospective, operator blinded, randomised controlled trial. SETTING:General dental practice, London. PARTICIPANTS:100 adult smokers. INTERVENTIONS:Participants completed a questionnaire on smoking, undertook a clinical examination, and received counselling in smoking cessation. Saliva samples were analysed at presentation and at eight weeks for salivary nicotine metabolites using a 10 minute semiquantitative point of care test. MAIN OUTCOME MEASURES:Smoking cessation measured by salivary nicotine metabolite values (scale 0-6), patient feedback on the perceived value of the test (visual analogue scale) in quitting, and reduction in tobacco use. RESULTS:A higher smoking quit rate was achieved with the point of care test (23% cases v 7% controls; P < 0.039), and overall tobacco use also decreased (68% cases v 28% controls; P < 0.001). Baseline values for salivary nicotine metabolites did not differ between the groups (cases, mean 4.1, SD 1.3 and 4.3, 1.4; P = 0.51). 87 participants reattended at eight weeks (44 cases, 43 controls). Mean nicotine metabolite values at eight weeks were 2.58 (2.0) for cases and 4.29 (1.8) for controls (P < 0.001). CONCLUSION:Incorporation of individualised personal feedback using a point of care test for salivary nicotine metabolites into a general practice based smoking cessation programme increased quit rates by 17% at eight weeks and reduced tobacco use.
