Feldman I, et al. - Via a study conducted in dental clinics in Sweden of 294 smokers aged 19–71 years, researchers carried out a cost-effectiveness analysis (CEA) of a high-intensity and a low-intensity smoking cessation treatment programme (HIT and LIT) using long-term follow-up efficiency data and confirmed the cost-efficiency outcomes based on short-term follow-up. The more costly HIT resulted in greater number of 6-month continuous abstinent participants following 1-year and greater number of sustained abstinent participants following 5–8 years, which translates into bigger societal costs avoided and health gains than LIT. The incremental cost/QALY of HIT in comparison with LIT using short-term and long-term effectiveness, amounted to €918 and €3786, respectively, which was acknowledged as very cost-efficient in Sweden. Thus, if decision makers are intended to spend at least €4000/QALY for tobacco cessation treatment, CEA favors the more expensive HIT.
