Anti-smoking programme for diabetic patients: the agony and the ecstasy.

It is generally accepted that people with diabetes should be encouraged to abstain from smoking but there are few data on the best strategy to implement this. In a preliminary survey of our diabetic patients, knowledge of the general and specific health effects of smoking was poor. In a prospective study of 70 diabetic smokers, only 50% agreed to participate in an anti-smoking programme, and the drop-out rate was high irrespective of whether the content of the programme was general or specific for diabetes. The enrollment rate was best 2 months after the diagnosis of diabetes and the drop-out rate was highest in patients recruited immediately following diagnosis. According to self-reported data, cigarette consumption fell after the first session of the anti-smoking programme but this could not be verified by the measurement of plasma cotinine. It is concluded that an anti-smoking counselling programme based on provision of information, within the context of a specialized diabetes centre, is not cost-effective.
