Cost-effectiveness of population-level proactive tobacco cessation outreach among socio-economically disadvantaged smokers: evaluation of a randomized control trial.

Population-level proactive tobacco treatment with personal telephone outreach was effective in achieving higher population-level quit rates and was cost-effective at various willingness-to-pay thresholds, compared with usual care (i.e. reactive treatment). Taken together with prior research, population-level proactive tobacco cessation outreach programs are judged to be highly cost-effective over the long term.
