Brief Interventions - Smoking C. Tyreman and K. Durkan
Objectives • Background • NICE recommendations • Consultation tips • Pharmacotherapy • Evidence base
Background • Smoking prevalence 20% (similar both sexes); highest in 20-24year olds; Yorkshire and Humber one of worse areas • Leading cause of morbidity / mortality; 460,000 hospital admissions related to smoking (5%); 80,000 deaths related to smoking (20%) • 67% want to give up; 75% have tried; £88 million spent on NHS stop smoking services
NICE recommendations • Brief interventions – opportunistic advice, discussion, negotiation and encouragement. • 5-10 min; patient centred; multi-disciplinary May include: • Simple advice to stop • Assessment of patients commitment to quit • Referral to more intensive support e.g. NHS Stop Smoking Services • Offer of pharmacotherapy / behavioural support
1) Advice to stop: • To all smokers • Have they considered stopping?/ do they know the risks? • QOF – identify smokers / give advice 2) Assess commitment • Advice should be sensitive to this – are they ready to stop?
3) Referral to intensive support • All who want to stop • NHS Stop Smoking Service, nurse specialist • QOF – offer support / Rx 4) Offer pharmacotherapy / behavioural support • In line with guidance – NRT, varenicline, bupropion; counselling; group support; self help literature • QOF – offer support / Rx
The Initial Consultation Why stop? How long smoked? Why smoke? Why stop now? Tried stopping before and how? When 1st cigarette / when last of the day?
Nicotine Replacement Therapy Prescribe two weeks initially NRT and medication no longer than 12 weeks Options Patches Inhalers Lozengers Gum Mouth / nose spray Microtabs
Varenicline Binds with nicotinic receptors and acts as an agonist. Alleviates symptoms of craving and withdrawal as well as reducing rewarding effect. SEs = GI disturbance, dry mouth, appetitie changes. AGITATION / DEPRESSION / SUICIDAL THOUGHTS. Cost = £163.80 for 12 weeks course
Bupropion Anti-depressant Alleviates crave and withdrawal symptoms but mode of action unclear. SEs = taste disturbance, GI upset, anxiety, CAUTION in previous seizures. Initially 150mg OD 6 days then BD 7-9 weeks. Cost = £71.73
The Evidence NRT v placebo All forms of NRT significantly more effective No significant difference between types Varenicline v placebo At 52 weeks varenicline 3x more effective Average quit 21% v 8% Buproprion v placebo 19% v 10% Varenicline v Bupropion Varenicline significantly more chance of quitting (21% v 14%)
Guidance on Therapies Initial prescription enough for 2 weeks after target stop date. Then re-asses. No repeat for 6 months if unsuccessful, unless special circumstances Can combine NRT therapies No combination of NRT / pharmacological.
So which Rx do I suggest? • NICE recommendations: • Discuss options with patient and decide • CIs and potential SEs • Patient preference • Availability of support and follow up • Likelihood of patient following treatment • Previous experience of smoking cessation
