Denominator: Adult males age 75 and over with no history of prostate cancer.

Note: Data for 2004, 2006, and part of 2008 precede the U.S. Preventive Services Task Force recommendation against screening men age 75 and over. It should be noted that PSA tests and DREs are provided to this population for purposes unrelated to prostate cancer screening. Data to determine the purpose of these services were unavailable and all reported PSA tests and DREs are reflected in the data shown.
2008 achievable benchmark: 62%.
