The primary aim of the proposed study is to conduct a randomized controlled trial (RCT) to evaluate the efficacy of the Interactive Mobile Doctor (iMD) intervention targeting 150 Chinese-, Korean- or Vietnamese-speaking male patients who smoke daily and have a scheduled clinic visit at Asian Health Services primary care.


The Asian American population is the fast-growing racial group during 2000 and 2010. Smoking prevalence among that Vietnamese (43%), Chinese (32%), and Korean (27%) men who spoke limited English are disproportionately higher than that of men of all races combined (17%). Thus, some Asian groups, including Chinese, Korean and Vietnamese, have an unequal burden of tobacco-related diseases. Asian Health Services (AHS) is a federally-qualified health center in Alameda County, California, providing services in English and 12 different Asian languages. The vast majority of the patients are Chinese, Vietnamese, and Korean with low income. Because of high smoking rates and associated health impacts on patients and their families, promoting smoking cessation is a health priority for AHS. The Vietnamese Community Health Promotion Project (VCHPP) at UCSF has conducted numerous intervention studies to promote smoking cessation among Asian Americans. Given the shared research interest, AHS and VCHPP have partnered to address smoking in Asian Americans. The partners received a TRDRP pilot Community-Academic Research Award grant to develop an interactive "Mobile Doctor" (iMD) intervention in Korean and Vietnamese languages that delivers video education tailored to patient's responses on a computer tablet during the clinic visit to enhance patient-provider discussion of tobacco use. The primary goal of the proposed study is to evaluate the iMD intervention with an expansion to the Chinese language in its efficacy to promote patient-provider discussion and quitting smoking in Chinese, Korean, and Vietnamese male smokers. The study will enroll 150 AHS Chinese-, Korean- or Vietnamese-speaking patients who smoke daily and have a scheduled clinic visit. Participants will then be assigned (by chance) into either receiving 1) iMD on tobacco or 2) video education on nutrition and physical activity recommendations. Participants will be assessed at: before the scheduled intervention visit, immediately after or within one week of the intervention visit, and 6 months following the intervention visit. Additional data will be obtained from EHR. The investigators anticipate that, when compared to participants receiving usual care alone, those who receive the iMD will be more likely to receive physician advice on their tobacco use both at their intervention visit and at one visit following the intervention visit within 6 months as documented in EHR; and at 6 months follow-up, those receiving the iMD will be more likely to report having been able to quit smoking for at least one day during the study period, and to have reported having quit smoking for at least 7 days with their abstinence status verified using a saliva sample. The long-term goal is to understand effective ways to enhance patient-provider communication in tobacco use and to leverage each clinic encounter in promoting smoking cessation among patients in community health settings.
