Nearly 14 million women in the United States underwent unnecessary Pap tests for cervical cancer screening in 2010, according to results of a cross-sectional study.
The US Preventive Services Task Force recommends against Pap tests for women who underwent hysterectomies because the majority no longer have a cervix, the target of the cancer screening test. The USPSTF also recommends against Pap tests for women aged older than 65 who have no history of cervical cancer or pre-cancerous conditions because the risk of developing cervical cancer at such a late stage in life is low.
“We knew there would be overuse of Pap tests because the few studies of cervical cancer screening showed overuse 10 years ago,” researcher Deanna Kepka, PhD, MPH, an investigator at the University of Utah’s Huntsman Cancer Institute and assistant professor in the university’s College of Nursing, said in a press release. “But we were shocked to see so little change over the past 10 years.”
Kepka and colleagues reviewed data from 9,494 women who participated in the 2010 National Health Interview Survey.
Researchers identified 2,278 women who reported having undergone hysterectomy. Of them, 34.1% (95% CI, 31.7-36.6) reported receiving a Pap test within the past year and 64.8% (95% CI, 62.2-67.3) reported receiving a Pap test after their hysterectomy.
Also, 58.4% (95% CI, 55.3-61.4) of women aged 65 years and older who had not undergone hysterectomy reported receiving a Pap test in the past 3 years.
Based on those screening rates, researchers projected 14 million women nationwide underwent unnecessary cervical cancer screening in 2010.
“We’re hoping to see better use of the tests over the next decade as changes in the health care infrastructure take place,” Kepka said. “Electronic medical records, health care provider reminder systems, decision support and new strategies to improve the quality of care may promote guideline-consistent practices among clinicians.”
