Smoking cessation
Intervention
Intervention: duration is 1 month with an initial face-to-face stage-matched smoking cessation counselling at the outpatient clinic (usually last for 2 - 30 minutes), and 10-minute telephone reminders at 1-week and 1-month, totalling in 40 - 50 minutes. The mean counselling times in the intervention group were 21.07 minutes at baseline, 12.70 minutes at 1-week follow up and 13.31 minutes at 1-month follow up.
Control: receive a healthy diet education manual from our study at the outpatient clinic after randomisation. The mean counselling time in the control group was 17.58 minutes.
Subjects in both groups received standard care after hospitalisation from the individual hospital which may be different from hospital to hospital. All the patients were followed up at 3-month, 6-month, and 12-month after initial contact and self-reported quitters were invited to participate in a urine cotinine test.
