Annual cost of stable coronary artery disease in France: A modeling study.

BACKGROUND: Few studies have analyzed the cost of treatment of chronic angina pectoris, especially in European countries. AIM: To determine, using a modeling approach, the cost of care in 2012 for 1year of treatment of patients with stable angina, according to four therapeutic options: optimal medical therapy (OMT); percutaneous coronary intervention with bare-metal stent (PCI-BMS); PCI with drug-eluting stent (PCI-DES); and coronary artery bypass graft (CABG). METHODS: Six different clinical scenarios that could occur over 1year were defined: clinical success; recurrence of symptoms without hospitalization; myocardial infarction (MI); subsequent revascularization; death from non-cardiac cause; and cardiac death. The probability of a patient being in one of the six clinical scenarios, according to the therapeutic options used, was determined from a literature search. A direct medical cost for each of the therapeutic options was calculated from the perspective of French statutory health insurance. RESULTS: The annual costs per patient for each strategy, according to their efficacy results, were, in our models, €1567 with OMT, €5908 with PCI-BMS, €6623 with PCI-DES and €16,612 with CABG. These costs were significantly different (P<0.05). A part of these costs was related to management of complications (recurrence of symptoms, MI and death) during the year (between 3% and 38% depending on the therapeutic options studied); this part of the expenditure was lowest with the CABG therapeutic option. CONCLUSION: OMT appears to be the least costly option, and, if reasonable from a clinical point of view, might achieve appreciable savings in health expenditure.

Cost effectiveness of full coverage of the medical management of smoking cessation in France.

OBJECTIVE: To estimate the incremental cost effectiveness of full coverage of the medical management of smoking cessation from the perspective of statutory health insurance (SHI) in France. DESIGN AND POPULATION: Cost-effectiveness analysis based on a Markov state-transition decision analytic model was used to compare full SHI coverage of smoking cessation and actual coverage based on an annual €50 lump sum per insured person among current French smokers aged 15-75 years. We used a scenario approach to take into account the many different behaviours of smokers and the likely variability of SHI policy choices in terms of participation rate and number and frequency of attempts covered. INTERVENTIONS: Drug treatments for smoking cessation combined with six medical consultations including individual counselling. MAIN OUTCOMES MEASURES: The cost effectiveness of full coverage was expressed by the incremental cost-effectiveness ratio (ICER) in 2009 euros per life-year gained (LYG) at the lifetime horizon. RESULTS: The cost effectiveness per LYG for smokers ranged from €1786 to €2012, with an average value of €1911. The minimum value was very close to the maximum value with a difference of only €226. The cost-effectiveness ratio was only minimally sensitive to the participation rate, the number of attempts covered and the cessation rate. CONCLUSIONS: Compared to other health measures in primary and secondary prevention of cardiovascular disease already covered by SHI, full coverage of smoking cessation is the most cost-effective approach.
