We developed a telephone-based smoking cessation program that was integrated as a routine clinical care option at five VISN 21 and VISN 22 facilities (38 clinic sites). Referrals to the program were generated by a provider during a visit through a brief consult in CPRS. Program staff then recruited patients and, after obtaining consent, enrolled the patients into treatment. Data were collected at the site level (quantity of referrals, service origins, etc.) and at the patient level (demographics, enrollment rates, abstinence rates at six months, etc.).
