Patterns of Prostate-Specific Antigen Test Use in the U.S., 2005-2015.

<bold>Introduction: </bold>Recommendations for prostate-specific antigen-based screening for prostate cancer are placing increasing emphasis on men aged 55-69 years. The goal of the current study is to describe patterns of population-based prostate-specific antigen testing with details about that age group.<bold>Methods: </bold>National Health Interview Surveys from 2005 to 2015 were analyzed in 2017 to estimate routine prostate-specific antigen testing in the past year from self-reported data by age group (40-54, 55-69, ≥70 years), and also by risk group, defined as African American men or men with a family history of prostate cancer versus other men. Differences between successive survey years by age and risk groups were assessed by predicted margins and rate ratios with 99% CIs, using logistic regressions.<bold>Results: </bold>Prostate-specific antigen testing among men aged 55-69 years decreased from a high of 43.1% (95% CI=40.3, 46.1) in 2008 to a low of 32.8% (95% CI=30.8, 34.7) in 2013, with no significant change in 2015 at 33.8% (95% CI=31.3, 36.4). Men aged ≥70 years had consistently high prevalence in all survey years, ranging from 51.1% in 2008 to 36.4% in 2015. African American men, men with a family history of prostate cancer, and other men showed a 5% absolute decrease over time, but this reduction was significant only in other men.<bold>Conclusions: </bold>Despite decreases, the absolute change in prostate-specific antigen testing for men aged 55-69 years was small (9.3%) over the study period. Men aged ≥70 years, for whom the benefits are unlikely to exceed the harms, continue to have consistently high testing prevalence. [ABSTRACT FROM AUTHOR]
