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

BACKGROUND: Given the public health relevance of PSA‐based screening, various professional organizations have issued recommendations on the use of the PSA test to screen for prostate cancer in different age groups. AIM: Using a large commercial claims database, we aimed to determine the most recent rates of PSA testing for privately insured men age 30 to 64 in the context of screening recommendations. METHODS AND RESULTS: Data from employer plans were from MarketScan commercial claims database. Annual PSA testing rate was the proportion of men with ≥1 paid test(s) per 12 months of continuous enrollment. Men with diagnosis of any prostate‐related condition were excluded. Annual percent change (APC) in PSA test use was estimated using joinpoint regression analysis. In 2011 to 2017, annual testing rate encompassing 5.02 to 5.53 million men was approximately 1.4%, age 30 to 34; 3.4% to 4.1%, age 35 to 39; 11% to 13%, age 40 to 44; 18% to 21%, age 45 to 49; 31% to 33%, age 50 to 54; 35% to 37%, age 55 to 59; and 38% to 41%, age 60 to 64. APC for 2011 to 2017 was −0.5% (P = .11), age 30 to 34; −3.0% (P = .001), age 35‐39; −3.1% (P < .001), age 40 to 44; −2.4% (P = .001), age 45 to 49; −0.2% (P = .66), age 50 to 54; 0.0% (P = .997), age 55 to 59; and −3.3% (P = .054) from 2011 to 2013 and 1.2% (P = .045) from 2013 to 2017, age 60 to 64. PSA testing rate decreased from 2011 to 2017 for age groups between 35 and 49 by 13.4% to 16.9%. CONCLUSIONS: 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.
