title: [Economic evaluation of a new selective COX-2 NSAID, rofecoxib, in a real practice context].
abstract: OBJECTIVE
  To evaluate the economic and health consequences of the use of a new COX-2 anti-inflammatory drug.
  
  
  METHODS
  Cost-effectiveness analysis by modelling three options for prescribing non-steroidal anti-inflammatories (NSAIDs) in patients diagnosed with arthrosis and undergoing long-term NSAID treatment. Option 1: NSAID prescription without gastric protection for low-risk patients, and with gastric protection for patients running a medium or high risk of developing complications (current procedure). Option 2: exclusive prescription of rofecoxib (25 mg/day) for all patients (high and low risk). Option 3: single-therapy rofecoxib (25 mg/day) prescription for patients sensitive to combined treatment (NSAIDs and gastric protection) due to the risk of complications. In each case, resources and expected clinical benefits were accounted for by the calculation of the cost of avoidance of each moderate or high gastro-intestinal side-effect (GISE) (symptomatic ulcer or complication) avoided. The direct economic impact on the centre of passing from option 1 to any of the other two options was calculated.
  
  
  METHODS
  The study, conducted in the Barceloneta Primary Care Centre, included in its modelling the 124 patients diagnosed with arthrosis who received NSAIDs continuously during the year 2000.
  
  
  RESULTS
  Option 2 supposed avoiding 1.5 cases of GISE (0.5 symptomatic ulcers and 0.9 serious complications), to an additional cost of 336 566.78 euros. Each case avoided would cost 24,641.50 euros; and each serious case avoided 38,464.79 euros. Option 3 avoided 0.25 cases of serious complication, at an additional cost of 9,015.18 euros. Avoiding one case would cost 37,262.75 euros.
  
  
  CONCLUSIONS
  The overall health benefits arising from the universal or partial introduction of a selective COX-2 inhibitor NSAID involve a unit cost of 24,040.48 or 36,060.73 euros, depending on the option. The impact on the Centre s pharmaceutical budget would increase by 1.3% under option 2, and by 0.35% under option 3.
