QALY, quality adjusted life year. aFrom the Spanish Health System, the cost-utility ratio threshold was set at € 23,153/QALY for 8 months in 2005; bpool rental + participation 20 persons per group + QALY differential at higher limit of 95% confidence interval; csalary 30% higher (monitor and nurse) + participation 10 persons per group + QALY differential at lower limit of 95% confidence interval. |
