 The long-term goal of the project is to develop a generalizable model for implementing evidence-based tobacco use treatment within existing health systems locally and globally. The objective of this proposal is to fill the current research-to-practice gap by conducting a randomized controlled trial that compares the effectiveness and cost of two practical and highly replicable strategies for implementing evidence-based guidelines for the treatment of tobacco use in public health clinics and community based settings in Vietnam. The proposed implementation strategies draw on evidence-based approaches and the WHOs recently released guidelines for implementing Article 14 of the Framework Convention on Tobacco Control FCTC. The FCTC is an evidence-based treaty that was developed by the WHO in response to the globalization of the tobacco epidemic Article 14specifies the need to integrate clinical best practices for treating tobacco use and dependence into routine preventive care. The proposed implementation strategies also build on the growing literature that supports the effectiveness of integrating community health workers as members of the health care team to improve access to preventive services.
