Study Summary
The purpose of this study is to test whether the integration of a smoke-free homes intervention into the clinical guidelines for tobacco cessation can encourage sustained smoking cessation in low-income primary care patients. The intervention consists of five components, three interactive mailings and two coaching calls, focused on creating home and vehicle(s) smoking bans among smokers.
Primary Outcome
Smoking cessation/abstinence is assessed as cotinine-validated 7-day point-prevalence abstinence at 12 months. Saliva samples were collected via mail from participants who report 7-day (and/or 30-day) point-prevalence abstinence at 12-month follow-up in order to examine cotinine levels to verify self-reported abstinence. A standard cut point for cotinine of 15 ng/ml is used to determine abstinence.
