title: Estimated cost of overactive bladder in Thailand.
abstract: OBJECTIVE
  To estimate the annual direct and indirect costs of overactive bladder (OAB) in indigenous Thai people aged 18 years and over in the year 2005.
  
  
  METHODS
  Economically based models using diagnostic and treatment algorithms from clinical practice guidelines and current disease prevalence data were used to estimate direct and indirect costs of OAB. Prevalence and event probability estimates were obtained from the literature, national data sets, and expert opinion. Costs were estimated from a small survey using a cost questionnaire and from unit costs of King Chulalongkorn Memorial Hospital.
  
  
  RESULTS
  The annual cost of OAB in Thailand is estimated as 1.9 billion USD. It is estimated to consume 1.14% of national GDP The cost includes 0.33 billion USD for direct medical costs, 1.3 billion USD for direct, nonmedical costs and 0.29 billion USD for indirect costs of lost productivity. The largest costs category was direct treatment costs of comorbidities associated with OAB. Costs of OAB medication accountedfor 14% of the total costs ofOAB.
