TI  - The influence of screening on the incidence of ruptured abdominal aortic 
      aneurysms.
PG  - 203-8
AB  - PURPOSE: The purpose of this study was to estimate the influence of a screening 
      program on the incidence and mortality of ruptured abdominal aortic aneurysms 
      (RAAAs). METHODS: The effects of screening on the incidence and death rate of 
      RAAAs were investigated with a stepped wedge study design. RAAAs that occurred in 
      the Huntingdon district were traced with an examination of all hospital records 
      and community postmortem records. RESULTS: During the 5-year period from 1991 to 
      1996, 78 RAAAs occurred in the Huntingdon district: 62 in men and 16 in women. 
      Eleven of the 62 men with RAAAs had been invited for screening. The incidence of 
      RAAA in the invited group was 3.7 per 10,000 person-years (py; 95% confidence 
      interval [CI], 1.5 - 7.3). In the noninvited group, the incidence was 7.3 per 
      10,000 py (95% CI, 5.3. - 9.2), a rate ratio of 0.51 (95% CI, 0.26 - 0.97). The 
      mortality of rAAAs in the invited group was 3.0 per 10, 000 py (95% CI, 1.4 - 
      5.4) as compared with 5.4 per 10,000 py in the noninvited group (95% CI, 3.9 - 
      7.3), resulting in a rate ratio of 0. 55 (95% CI, 0.26 - 1.15). CONCLUSION: 
      Screening for asymptomatic AAAs can reduce the incidence rate of RAAAs by 49% 
      (95% CI, 3% - 74%).
