title: Clinical trial: the incidence and early mortality after peptic ulcer perforation, and the use of low-dose aspirin and nonsteroidal anti-inflammatory drugs.
abstract: BACKGROUND
  It is not clear whether the incidence or early mortality related to peptic ulcer perforation has changed.
  
  
  OBJECTIVE
  To evaluate the incidence and mortality related to peptic ulcer perforation while considering the intake of low-dose aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs).
  
  
  METHODS
  We recorded the numbers and details of all patients presenting in our region of Scotland with perforation between 1997 and 2006 including demography, drug usage and 30-day mortality.
  
  
  RESULTS
  In subjects aged >65 years, the annual incidence of perforation was 32.7 per 10(5) of the age-specific population, of whom 10.7 per 10(5) were taking low-dose aspirin and 12.0 taking NSAIDs. These were all significantly higher (P < 0.001) than the corresponding incidence in subjects aged < or =65 years (6.6 per 10(5) overall, 1.1 taking aspirin and 2.5 taking NSAIDs). There was an increasing trend with time in the number of patients taking NSAIDs (chi(2) = 4.57, P = 0.03). Using univariate analysis, 30-day mortality was associated with aspirin [odds ratio, 2.32 (95% C.I., 1.20-4.47), P = 0.01] but not with NSAIDs. The strongest predictors of mortality were increasing age and comorbidity.
  
  
  CONCLUSIONS
  Perforation remains common in elderly patients including users of NSAIDs and aspirin. Early mortality is also noted in association with increasing age and comorbidity, but not independently with drug intake.
