A pilot study to implement and sustain the US PHS clinical practice guidelines for treating tobacco use and dependence in free clinics, a safety net care setting for the uninsured

Uninsured patients are more likely than the general population to use tobacco and less likely to quit.To determine if the mode of delivering the PHS Guidelines influenced the effectiveness of smoking cessation among patients in a safety net setting.Six free clinics were randomly assigned to a training program delivered by an academic physician or community partner plus video support. A repeated cross-sectional survey of patients was conducted at three waves to assess effectiveness to promote quitting.Tobacco use was triple the rate of the US population: 57.7% (Wave 1), 44.7% (Wave 2), and 48.9% (Wave 3). Patients were more likely to report receipt of at least one evidence-based strategy to promote quitting at Wave 2 (AOR = 2.33, 95% CI (1.18–4.58)). Patients treated in clinics trained by the community partner were significantly more likely to report receiving cessation assistance at Wave 2 (AOR 2.54, 95%CI 1.29–5.00) and the trend was similar, but not significant at Wave 3. Patients in the community partner-led arm were significantly less likely to report tobacco use at Wave 3 (AOR 0.59, 95% CI 0.35–0.99).Implementation of the PHS Guidelines in free clinics demonstrates preliminary efficacy, with delivery by community partners offering greater scalability.
