title: Modeling the cost-effectiveness of galantamine for mild to moderately severe Alzheimer's disease in Korea.
abstract: OBJECTIVE
  The aim of the study was to determine the cost-effectiveness, from the third-party payer viewpoint, of galantamine compared with usual care in the treatment of mild to moderately severe Alzheimer's disease (AD).
  
  
  METHODS
  An existing Markov model was adapted to Korea to predict long-term outcomes over a 5-year time horizon and to estimate the cost-effectiveness of galantamine for the treatment of AD. The model structure is informed by a review of national and international literature on the clinical and cost-effectiveness of galantamine and on the costs and outcomes associated with treatment for AD. The main outcome measure used was the cost per quality-adjusted life year (QALY) gained. All costs were indexed to US$ (2007 value). Multivariate probabilistic sensitivity analysis and scenario analysis were undertaken to assess uncertainty in the results.
  
  
  RESULTS
  The study findings indicate that the clinical benefits on AD progression from galantamine treatment resulted in an incremental cost per QALY gained of US$4939 over 5 years (vs. usual care). Probabilistic sensitivity analysis and cost-effectiveness acceptability curve suggest that the probability of galantamine treatment having an incremental cost per QALY over US$6740 is zero. Incremental cost per QALY gained according to scenario analyses ranged from US$2271 to US$8335.
  
  
  CONCLUSIONS
  These findings suggest that the use of galantamine may be a cost-effective use of Korean national health-care resources, considering the gross domestic product per capita of US$21,695 in 2007.
