About
Primary: To test whether the delivery of A3-5 smoking cessation counseling (Assess, Assist, Arrange) in primary care offices is enhanced by a system that couples (1) an expanded vital sign intervention with (2) fax referral of preparation-stage patients for telephone counseling and (3) feedback to the provider. The question will be examined in a randomized trial, with practices as the unit of analysis and with a control intervention consisting of a conventional vital sign intervention. The experiment will therefore compare what intervention and control practices accomplish beyond simply identifying patients who use tobacco.
Secondary: To assess contextual factors that might affect implementation of the intervention and account for its ultimate success or failure. In particular, to assess: (1) environmental and practice-level factors that affect practices' ability to successfully implement and use the intervention and; (2) patient characteristics beyond readiness to change (i.e., age, gender, race/ethnicity) that affect willingness to use the quit line and complete counseling.
Full description
Among the most important evidence-based interventions in primary care is to offer counseling and pharmacotherapy to patients who use tobacco, but studies suggest that only a fraction of tobacco users receive this assistance. Office systems and other strategies can improve counseling rates but are not widely adoptable in primary care. We propose a novel solution that couples a simple office system, which is widely adoptable, with a form of third-party counseling (telephone quit lines) that most practices can access in the United States. Specifically, the three-part intervention includes (1) an in-office expanded "vital signs" intervention that prompts nurses (or medical assistants) to determine tobacco use status, offer brief advice, and assess readiness to quit as vital signs are obtained; (2) inviting preparation-stage tobacco users to obtain proactive telephone counseling (provided by the American Cancer Society) comprising three 30-minute sessions scheduled at the patient's convenience; and (3) feedback from the Society to the practice, including fax requisitions for prescription aids for quit attempts, progress reports on the results of counseling, and quarterly aggregate analyses of practice and clinician team referral outcomes. The Virginia Ambulatory Care Outcomes Research Network will partner with the American Cancer Society to test this strategy in a randomized controlled trial conducted at 16 primary care practices in Virginia. Because existing dissemination strategies serve mainly to increase identification of tobacco users and sometimes to increase brief advice, our primary outcome measure will be the proportion of tobacco users who receive substantive assistance: Assess, Assist, and Arrange of the 5As. Given the widening availability of state and national quit line programs, our model for referrals and bidirectional communication with primary care could markedly augment the effectiveness of both primary care and quit lines in promoting tobacco cessation and provide an attractive alternative for clinicians who lack the time and resources to provide effective counseling.
