Dissemination of a tobacco cessation program for unionized workers.

Many multilevel, contextually relevant, evidenced-based health promotion programs are not disseminated widely. The purpose of this study is to describe the adaptation of a published effective tobacco-use cessation intervention, which was implemented and evaluated in a broader population of unionized workers partnering with a health and welfare fund health benefits carrier. 68 tobacco users enrolled. Implementation and effectiveness outcomes indicated that most participants (69%) completed all counseling calls and at 16 weeks' follow-up, 30.9% reported not using tobacco. The intervention had relatively high levels of implementation, effectiveness, and acceptability, but low reach, highlighting issues arising during dissemination.
