We randomly allocated all participating sites within VISNs 21 and 22 to either self-help or intensive counseling treatment arms. We randomly allocated each week of program referrals to either proactive or reactive care coordination. All patients received brief smoking cessation counseling from their primary care physician, smoking cessation medications (after study enrollment by the VA care coordinator), and a follow-up call at 6 months. Care coordination was provided by VA clinical staff (donated as in-kind support from the participating facilities). Intensive counseling was provided by the California Smokers' Helpline.
