Background and challenges to implementation:
Thailand National Quitline (TNQ) has been established in order to provide smoking cessation service for Thai smokers. Almost a decade, the TNQ has been promoted based on television advertising which were very costly. Consequently, this study aims to develop the consolidation between the TNQ service and primary care service in order to Increasing reach for smoking cessation service in primary care setting in accordance with the policy of The WHO Framework Convention on Tobacco Control (WHO FCTC). Furthermore, this will be a new approach for effective and sustainable quitline promotion strategy.

Intervention or response:
The study design was a quasi- experimental design which divided the subjects into experimental (n = 123) and control (n = 108) groups from primary health care community centers. For the experimental group, the subjects received brief intervention aimed at increasing intention to quit by village health volunteers who were trained and equipped with smoking cessations toolkits for providing smoking cessation service in primary care settings, whereas the control group the subjects received usual care. Relative risk was used to analyze the ratio of the probability of the outcomes between experimental and control group.

Results and lessons learnt:
The findings revealed that participants in the experimental group, 62.60% in the control group, 5.56% [RR 28.46 (95%CI = 11.56, 70.04)] could access to smoking cessation service by the TNQ. It is considered that the new intervention can successfully Increasing reach for Thai smokers in the community, thus, Increasing smoking service accessibility. .

Conclusions and key recommendations:
Promoting the TNQ service in the primary care setting significantly increased the proportion among Thai smokers to access the smoking cessation service. Consequently, the expanded reach to smoking cessation service in primary care setting are advantageous for smokers in community.
