Intimate partner violence
Another change from a previous “I” statement pertains to intimate partner violence (IPV). The TF now recommends screening women of childbearing age for IPV and either providing intervention services for those who screen positive for IPV or referring for services. Reproductive age is defined as 14 to 46 years, although the TF admits that most studies have looked at women ≥18 years.11 Most of the benefits from screening and counseling have been demonstrated in pregnant women.
IPV can include physical, sexual, or psychological harm by a current or former partner or spouse, and it is not limited to opposite sex couples.11 Screening tools with the highest sensitivity and specificity include the Hurt, Insult, Threaten, and Scream (HITS) scale. Potential interventions include counseling, home visits, information cards, referrals to community services, and mentoring support.
While the TF acknowledges that both child abuse and elder abuse are prominent problems, there is not enough evidence to assess and recommend interventions.11,12
D recommendations
There were 4 “D” recommendations (recommend against) in 2013: testing for BRCA or using tamoxifen or raloxifene in women at low risk of breast cancer; using β-carotene or vitamin E to prevent CVD and cancer; and using low doses of vitamin D and calcium to prevent fractures in noninstitutionalized postmenopausal women (TABLE 2). In each instance the harms of the intervention were deemed to exceed potential benefits.
I statements
The TF still finds little evidence to support some common practices (TABLE 3). Physicians who use these interventions should realize that the TF, after thorough systematic reviews of the available evidence, does not find enough evidence to assess their relative benefits and harms. A description of the evidence on each condition can be found in the recommendations section of the USPSTF Web site (http://www.uspreventiveservicestaskforce.org/uspstopics.htm).
