dc.description.abstractThe USPSTF recommends a 1-time screening for abdominal aortic aneurysm (AAA) with ultrasonography (US) in men above 65 who have ever smoked. AAA screening has substantially reduced rupture rates. It has been suggested, however, that rates of screening may be well lower in rural areas. The ROME department initiated a quality improvement measure to increase rates of AAA screenings by means of medical students equipped with hand-held US devices. Consenting men above 65 who have ever smoked received an outpatient, point of care ultrasound (POCUS) AAA screening via Butterfly iQ. Screenings of the proximal, middle, and distal portions of the abdominal aorta in both longitudinal and transverse views were conducted. Patients were then referred to the appropriate radiological services to receive a one-time ultrasound screening for AAA. The outcomes compared the variability between the students' and radiologists' measurements and radiology referral compliance. 17 patients were screened in the clinic using the handheld ultrasound device. 2 patients screened positive for AAA at the radiology department, while 1 screened positive in the clinic. The average difference between the measurements by the students and the radiologists was -0.2 cm (95% CI, -0.44 to 0.04; P=0.1). Results yielded no significant difference between measurements obtained by the medical students and the radiology department. The patient follow up compliance rate was only 59%. Based on these data, medical student-performed POCUS AAA screening may provide better compliance and similar accuracy compared to traditional AAA screening.
