IntroductionThe 2012 national cervical cancer screening guidelines recommended cessation of screening after age 65 years in women with adequate prior screening. In this retrospective cohort study, adherence to these screening exit guidelines was examined.MethodsWomen who turned age 66 years in 2012-2013 at Kaiser Permanente Southern California were followed through age 68 years for cervical cancer screening uptake. Adequacy of prior screening was assessed between age 56 and 65 years using electronic medical records. Guideline adherence was determined based on screening pattern between age 66 and 68 years. Patient- and physician-level correlates for guideline adherence were examined using multivariable logistic regression. Data collection and analyses were conducted in 2018.ResultsA total of 14,778 women were included; 24% did not have adequate prior screening by age 65 years. Among those without adequate prior screening, the proportion screened after age 65 years ranged from 71% (177 of 249) in those whose most recent test was abnormal to 3% (34 of 1,330) in those who did not have any testing in 10 years. Prior screening pattern was the only factor associated with screening after age 65 years. Of those with adequate prior screening, 10% (1,135 of 11,295) continued to receive screening after age 65 years. Frequent office visits and having a male primary care physician were associated with continuing screening after age 65 years.ConclusionsA considerable proportion of women did not have adequate prior screening by age 65 years. Of these, a large proportion did not receive screening after age 65 years, except those who had a recent abnormal screening result. Further research is needed to understand barriers for guideline adherence and rationales for clinical decision making.Copyright © 2019 American Journal of Preventive Medicine.
