Use of the prostate-specific antigen test in the U.S. for men age 30 to 64 in 2011 to 2017 using a large commercial claims database: Implications for practice interventions.

Based on these data, PSA testing rate has modestly decreased from 2011 to 2017. These results, however, should be considered in view of the limitation that MarketScan claims data may not be equated to actual PSA testing practices in the entire U.S. population age 30 to 64. Future research should be directed to understand why clinicians continue ordering PSA test for men younger than 50.
