Smoking cessation in patients with diabetes mellitus: results from a controlled study of an intervention programme in primary healthcare in Sweden.

OBJECTIVE: To evaluate an intervention programme on smoking cessation in patients with diabetes mellitus in primary healthcare.
DESIGN: Regional controlled intervention study.
SETTING: Seventeen primary healthcare centres in Sweden. INTERVENTION: In the intervention centres, nurses with education in diabetes were given one half-day of training in motivational interviewing and smoking cessation. An invitation to participate in a smoking cessation group was mailed to patients from the intervention centres followed by a telephone call from the patient's diabetes nurse. The nurses who intervened were specially educated in smoking cessation. The control group received a letter containing advice to stop smoking and information about a one-year follow-up. PATIENTS: Daily smokers with diabetes mellitus, 30-75 years of age. In the intervention centres 241 patients fulfilled the criteria and in the control centres 171 patients. MAIN OUTCOME MEASURES: Self-reported smoking habits after one year.
RESULTS: In total, 21% of the smokers accepted group treatment. After 12 months, 20% (42/211) in the intervention centres reported that they had stopped smoking and 7% (10/140) in the control centres; 40% (19/47) of the smokers who had participated in group treatment reported that they had stopped smoking.
CONCLUSION: A computerized record system for patients in primary healthcare was used to identify diabetic patients who were smokers. The selected group was invited to a stop smoking programme. At a one-year follow-up significantly more patients in the intervention centres had stopped smoking compared with patients in the control centres.
