Since the last Practice Alert update on recommendations made by the US Preventive Services Task Force,1 the Task Force has completed work on 12 topics (TABLE 1).2-17 Five of these topics have been discussed in JFP audio recordings, and the links are provided in TABLE 1.
This latest Task Force endeavor resulted in 18 recommendations (TABLE 2), all of which reaffirm previous recommendations on these topics and expand the scope of 2. There were 2 “A” recommendations, 6 “B” recommendations, 2 “D” recommendations, and 8 “I” statements, indicating that there was insufficient evidence to assess effectiveness or harms. The willingness to make “I” statements when there is little or no evidence on the intervention being assessed distinguishes the USPSTF from other clinical guideline committees.
Screening for carotid artery stenosis
One of the “D” recommendations this past year reaffirms the prior recommendation against screening for carotid artery stenosis in asymptomatic adults—ie, those without a history of transient ischemic attack, stroke, or neurologic signs or symptoms that might be caused by carotid artery stenosis.2 The screening tests the Task Force researched included carotid duplex ultrasonography (DUS), magnetic resonance angiography, and computed tomography angiography. The Task Force did not look at the value of auscultation for carotid bruits because it has been proven to be inaccurate and they do not consider it to be a useful screening tool.
The Task Force based its “D” recommendation on a lack of evidence for any benefit in detecting asymptomatic carotid artery stenosis, and on evidence that screening can lead to harms through false-positive tests and potential complications from carotid endarterectomy and carotid artery angioplasty and stenting. In its clinical considerations, the Task Force emphasized the primary prevention of atherosclerotic disease by focusing on the following actions:
- screening for high blood pressure in adults
- encouraging tobacco smoking cessation in adults
- promoting a healthy diet and physical activity in adults with cardiovascular risk factors
- recommending aspirin use to prevent cardiovascular disease and colorectal cancer
- advising statin use for the primary prevention of cardiovascular disease in adults ages 45 to 75 years who have 1 or more risk factors (hyperlipidemia, diabetes, hypertension, smoking) and those with a 10-year risk of a cardiovascular event of 10% or greater.
This “D” recommendation differs from recommendations made by other professional organizations, some of which recommend testing with DUS for asymptomatic patients with a carotid bruit, and others that recommend DUS screening in patients with multiple risk factors for stroke and in those with known peripheral artery disease or other cardiovascular disease.18,19
Smoking cessation in adults
Smoking tobacco is the leading preventable cause of death in the United States, causing about 480,000 deaths annually.3 Smoking during pregnancy increases the risk of complications including miscarriage, congenital anomalies, stillbirth, fetal growth restriction, preterm birth, and placental abruption.
The Task Force published recommendations earlier this year advising all clinicians to ask all adult patients about tobacco use; and, for those who smoke, to provide (or refer them to) smoking cessation behavioral therapy. The Task Force also recommends prescribing pharmacotherapy approved by the Food and Drug Administration (FDA) for smoking cessation for nonpregnant adults. (There is a lack of information to assess the harms and benefits of smoking cessation pharmacotherapy during pregnancy.)
