Late in 2009, a change in the recommendations of the US Preventive Services Task Force (USPSTF) brought more public attention to this panel than it had ever experienced before. This publicity centered on revised recommendations on breast cancer screening that pointed out that mammograms benefit a few women under 50, but are also associated with some harms. The Task Force recommended that patients and physicians discuss these potential benefits and harms and make an individual decision about whether to have a mammogram.1
Even though the criticism was loud—and harsh—from some sectors, many professional organizations, including the American Academy of Family Physicians, the American College of Physicians, and the American College of Preventive Medicine, came to the defense of the Task Force and its rigorous, evidence-based methodology.2-4 Both the Journal of the American Medical Association and the Annals of Internal Medicine have since published a series of articles and opinions on the controversy, most of them favorable to the Task Force and its methods.2-9
Lost in all the brouhaha were a number of other, less controversial recommendations that the Task Force made in 2009 (and early 2010). You can find them at www.ahrq.gov/clinic/uspstfix.htm. They are categorized by strength of recommendation (TABLE 1) and listed in TABLES 2 and 3. Family physicians should review the A and B recommendations and try to incorporate those into practice. At the same time, we should avoid services in the D category, as the evidence is strong that they are not effective or cause more harm than benefit. The C and I recommendations leave more discretion for physicians and patients to decide on these interventions based on personal values and risks. A C recommendation means the service can benefit some individuals, but the totality of benefit is small. An I recommendation means that evidence is insufficient to evaluate benefits vs harms.
TABLE 1
US Preventive Services Task Force recommendation categories
Grade | Definition |
---|---|
A | The USPSTF recommends the service. There is high certainty that the net benefit is substantial. |
B | The USPSTF recommends the service. There is high certainty that the net benefit is moderate or there is moderate certainty that the net benefit is moderate to substantial. |
C | The USPSTF recommends against routinely providing the service. There may be considerations that support providing the service in an individual patient. There is at least moderate certainty that the net benefit is small. |
D | The USPSTF recommends against the service. There is moderate or high certainty that the service has no net benefit or that the harms outweigh the benefits. |
I | The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of the service. Evidence is lacking, of poor quality, or conflicting, and the balance of benefits and harms cannot be determined. |
