Screening for abdominal aortic aneurysm by general practitioners and practice-based ultrasonographers

Area of Science:

• Vascular Surgery
• Primary Care Medicine
• Public Health Screening

Background:

• Abdominal aortic aneurysm (AAA) is a significant vascular condition.
• Early detection through screening can improve patient outcomes.
• Organizing screening services within primary care settings presents unique challenges and opportunities.

Purpose of the Study:

• To evaluate the feasibility of organizing AAA screening within a general practice setting.
• To assess the potential for a primary care trust (PHCT) to offer a screening service to surrounding general practices.
• To determine the effectiveness and cost-efficiency of a community-based AAA screening program.

Main Methods:

• The study involved screening men aged 65–80 years for abdominal aortic aneurysm (AAA).
• Screening was conducted entirely within primary care general practices equipped with ultrasound facilities.
• The project was funded by a local PHCT, with all costs managed within the allocated budget.

Main Results:

• An attendance rate of 71.7% was achieved among the eligible male population.
• The prevalence of abdominal aortic aneurysm (AAA) was found to be 4.1% in the screened cohort.
• The approximate cost per scan was £17.39, indicating a cost-effective screening approach.

Conclusions:

• Primary care-based AAA screening is feasible and can be organized effectively.
• While attendance rates can be improved, the prevalence of AAA detected is comparable to hospital-led trials.
• The low cost of this community-based screening program suggests a viable model for broader implementation.
