Screening for Abdominal Aortic Aneurysms in the General Practice by Ultraportable Ultrasound (DACEP)
Screening for Abdominal Aortic Aneurysms in the General Practice by Ultraportable Ultrasound: Cluster Randomized Controlled Prospective Multicenter Study in Two Parallel Groups 1:1 in Open-label
Abdominal aortic aneurysm (AAA) is a localized dilatation of a segment of the aorta artery in its abdominal portion. It affects 1.7% of men aged 65 years and older. In the high-risk population (male smokers aged 65-75 years), its prevalence is estimated to be between 2.8 and 9%. Mortality of ruptured AAAs is high (80% of deaths before hospitalization or perioperatively), whereas mortality of scheduled procedures for unruptured AAAs is less than 5%. AAA screening has been shown to significantly reduce the specific mortality rate in the medium and long term. The French National Authority for Health (HAS) recommends targeted screening for AAA by ultrasound at the radiologist. The target population is male smokers or former smokers aged 65 to 75 years, as well as all persons aged 50 to 75 years with a family history of AAA. Despite recommendations, the rate of access to targeted screening appears low. Ultrasound screening for AAA is a rapid, noninvasive, and reproducible test. It relies primarily on the measurement of the maximum diameter of the abdominal aorta in cross-section. It has been demonstrated that the learning of the ultrasound screening procedure for AAA is very fast and that the performance of non-radiologists trained in this procedure alone is similar to that of radiologists.
In addition, new ultra-portable ultrasound devices, inexpensive and with validated performances have appeared on the market in the last few years, making it possible to equip general practitioners (GPs). We propose a simplified care pathway for AAA screening, by equipping GPs with an ultra-portable ultrasound scanner and by training them to perform the screening procedure, which will be performed in the office or at the patient's home, during a usual consultation of general medicine. Our hypothesis is that this new organization will allow better access to screening for the target population, at a lower cost, compared to the current screening method recommended by the HAS (referral of the patient to the radiologist).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: screening by a GP
Each patient in this group will have a screening for AAA performed by a trained general practitioner
|
The GPs included in the experimental group will be trained in AAA screening with an ultra-portable ultrasound machine and will keep an ultrasound machine available (Butterfly iQ+ model).
Their patients will be able to be screened by the GP in the office or at home.
In case of positive screening, the GP will be able to refer the patients to the radiologist for diagnostic confirmation..
|
Other: screening by a radiologist (conventional)
Each patient in this group will have AAA screening performed by a radiologist
|
General practitioners in the control group will refer their patients to the radiologist for AAA screening.
