A Longitudinal Study of Medical Practices' Treatment of Patients Who Use Tobacco.

INTRODUCTION: Many patients who use tobacco have never been encouraged by their healthcare providers to quit. In recent years, incentives have been provided for medical practices to incorporate tobacco-cessation processes into routine care. This study examined growth in use of these processes as well as organizational and policy factors associated with their implementation.

METHODS: Data from three National Study of Physician Organizations surveys fielded in 2006-2013 were analyzed in 2014. The analyses estimated multivariate longitudinal and cross-sectional linear regression models to assess the relationship between implementation of cessation processes and change in practices' characteristics and external incentives, including state mandates for tobacco-cessation coverage.

RESULTS: Systematic identification of patients who use tobacco increased in large (26% to 91%, p<0.0001) and small-medium practices (69% to 83%, p<0.0001). Neither routine advice to quit nor referral to counseling and guideline-based point-of-care reminders increased. Practice feedback to physicians on their use of cessation interventions increased (18% to 29%, p<0.0001) for small-medium practices. State-mandated coverage was associated with the use of cessation processes in small-medium practices (p<0.0001), as was pay for performance participation (p<0.0001); public reporting (p<0.0001); Medicaid revenue (p=0.02); and practice size (p<0.0001). Among large practices, predictors were practice size (p<0.0001); hospital ownership (p=0.004); public reporting (p=0.03); and primary care practice (p=0.04).

CONCLUSIONS: The findings suggest that state-mandated coverage for tobacco-cessation treatment and increased use of external incentives such as pay for performance and public reporting programs may improve care for patients who use tobacco.
