Intervention Trial of Culturally-Appropriate Decision Aids for Smoking Cessation
Despite the establishment of various smoking cessation methods, including pharmacological intervention, only a small proportion of smokers who visit doctors choose to receive such assistance. Such under-utilization is especially apparent in some cultures, as in the case of Korea, where a government survey showed that only 0.5% of current or formal smoker reported they had been prescribed smoking cessation medication. Shame in asking for help for an addictive disorder has been recognized as one of the most recognized cultural barrier in Asian-American population. It is clear that culturally focused studies on smoking cessation is warranted.
Patient decision aids are tools that help people become involved in decision making by providing information about the options and outcomes and by clarifying personal values. Patient decision aids have been developed to help patients decide whether to quit smoking or not, or whether to use smoking medication or not. However, such previous studies have only been focused on western populations.
The main purpose of this study is to develop a culturally appropriate decision aid for smoking cessation for the Korean population, as well as evaluate its effect on their decision to use smoking cessation medication. The investigators expect that culturally tailored smoking cessation decision aids would increase knowledge about efficacy of smoking cessation, make people have more positive attitudes toward smoking cessation medication, encourage people to discuss about smoking cessation medication with their physicians. Ultimately the investigators expect it would increase usage of smoking cessation medication and enhance the quitting rate of smoking, which is a very important clinical issue.

|Official Title:||Development and Application of Culturally-Appropriate Decision Aids for Smoking Cessation in Korea: a Single Arm Intervention Trial With Historical Control|
- Proportion of Smokers Who Are Prescribed Smoking Cessation Medication [ Time Frame: 1 month after viewing decision aids ]Patients who visited primary care clinic and health screening center were to be targeted for recruitment of the study. Current smokers seen by physician allocated into intervention group were provided with Smoking Cessation Decision Aids. The proportion of smokers who are prescribed smoking cessation medication within 1 month after reading Decision Aids will be compared with that of control group. The information will be recruited from medical chart.
- Abstinence Rate (Point Prevalence) [ Time Frame: 6 months after viewing decision aids ]Participants are assessed for their abstinence rate according to their choices via telephone interview, as the final outcome of the study. The abstinence rate of patients in intervention arm will be compared with that of control arm
- Proportion of Smokers Who Are Prescribed Smoking Cessation Medication [ Time Frame: 6 month after viewing decision aids ]Participants are expected to choose from various treatment choices after initially viewing the decision aids, from no treatment to smoking cessation medication. Proportion of smokers who are prescribed smoking cessation medication within 6 months after reading Decision Aids will be compared with that of control group. The information are assessed via telephone interview.

Experimental: Intervention group
This study is cluster randomized trial, and the randomization level is physician. Current smokers seen by physician allocated into intervention group were provided with Smoking Cessation Decision Aids along with study questionnaires. The intervention was Smoking Cessation Decision Aids provided to current smokers.
Device: Smoking Cessation Decision Aids
The decision aids were developed through: 1) literature review; 2) qualitative interviews with Korean smokers from various backgrounds; 3) expert opinions. They were in the form of short educational videos (flash), displayed by Apple's iPad.
The decision aids contained the followings, in proper Korean social and cultural context:
The choices given in the decisions aid were:
No Intervention: Control group
Current smokers seen by physician allocated into control group were provided with only study questionnaires and usual care.
