Long-term results of a smoking reduction program.

Area of Science:

• Health Services Research
• Behavioral Science
• Public Health

Background:

• Limited comprehensive evaluations exist for smoking reduction interventions within healthcare systems.
• Understanding the cost, maintenance, and subgroup robustness of smoking reduction is crucial.

Purpose of the Study:

• To evaluate a theory-based smoking reduction intervention combining telephone counseling and tailored newsletters.
• To assess the cost, maintenance, and robustness of the intervention across patient subgroups.

Main Methods:

• A randomized controlled trial involving 320 adult smokers from an HMO.
• Intervention group received enhanced usual care plus telephone counseling and newsletters.
• Control group received enhanced usual care; outcomes measured by self-report, carbon monoxide, and costs.

Main Results:

• Both groups showed improvement, but no significant between-group differences in smoking reduction at 12 months.
• 25% in the intervention group and 19% in the control group achieved ≥50% smoking reduction.
• The intervention was robust across various patient characteristics (education, ethnicity, health literacy, dependence).

Conclusions:

• The smoking reduction intervention showed modest, nonsignificant long-term effects without nicotine replacement therapy.
• Future research should focus on enhancing intervention efficacy and conducting detailed economic analyses.
• Further investigation into program variations and economic impacts is warranted.
