title: Project PROMIS: Peoria Regional Outpatient Medical Imaging Study.
abstract: BACKGROUND
  Abdominal aortic aneurysm (AAA) accounts for > 15,000 reported deaths annually. Early screening in high-risk populations is important to decrease morbidity and mortality from rupture.
  
  
  METHODS
  A prospective, population-based study of free ultrasound-based AAA screening was conducted from July 2004 to December 2006. Before examination, subjects completed surveys asking their medical history, including known AAA risk factors. Incidence rates and comparison analyses were performed.
  
  
  RESULTS
  The final analysis included 979 patients, of whom AAA was discovered in 27 (2.8%). AAA was found in only male patients > 60 years old (4% of the male population). AAA size ranged from 3 to 10 cm. Of patients diagnosed with AAA, 85% were current or past smokers, and 70% had hypercholesterolemia. There was a 6% incidence of AAA in male smokers > or = 60 years old who had hypercholesterolemia.
  
  
  CONCLUSIONS
  Four factors were predominant in our population of patients with AAA: patient age, male sex, smoking history, and hypercholesterolemia.
