What grade does USPSTF assign to abdominal aortic aneurysm screening for men 65 to 75 who have ever smoked?

• A. Grade A
• B. Grade B
• C. Grade C
• D. Grade D

Answer: (B)

The key point is how USPSTF grades preventive services. For abdominal aortic aneurysm screening in men aged 65 to 75 who have ever smoked, the Task Force recommends a one-time ultrasound because evidence shows a meaningful reduction in aneurysm-related deaths from detecting aneurysms before rupture and treating them electively. The grade given reflects moderate certainty that the net benefit is substantial, not high certainty. So while the benefit is clearly present, it isn’t judged with the highest level of certainty across all populations, which is why it’s not Grade A. The balance of benefits to harms in this group supports screening, whereas in women or men who never smoked the balance is less favorable or less certain.
