Economic evaluation of an educational campaign for early diagnosis of cutaneous melanoma.
Public educational campaigns for the early diagnosis of cutaneous melanoma are considered an effective approach in the prevention of this disease, since they increase the number of cases detected early and consequently lengthen patients' life expectancy. We performed an economic evaluation of such a campaign in Bergamo, Italy, in order to quantify its costs and consequences. We used cost-effectiveness analysis to compare the costs and effects of the campaign with those of the 'do nothing' option. The analysis was performed from the perspective of the Italian National Health Service [the Servizio Sanitario Nazionale (SSN)]. Accordingly, only direct costs related to publicly financed healthcare services were considered. No indirect costs or benefits were considered because they are not relevant to the SSN. Incremental analysis was used to obtain results in terms of additional costs per life-year saved (LYS). Overall LYS were quantified by comparing the survival curves for 4 subgroups of patients with different lesional thicknesses at diagnosis ( < 0.76mm, 0.76 to 1.50mm, 1.51 to 3.00mm and > 3.00mm). All costs were estimated in 1993 Italian lire (L). Overall effectiveness amounted to 233.49 LYS. Using a 5% discount rate, the value of effectiveness was 171.3 LYS. The total cost of the educational campaign (i.e. the sum of the organisational and 'induced' costs minus the costs saved) was estimated at L817 million (approximate 1993 exchange rate $US1 = L1573), and L905 million after discounting at a rate of 5%. Thus, using discounted cost and effectiveness data, the cost of the educational campaign was L5.28 million per LYS.
