    Drop in PSA screening greatest among urologists

    The U.S. Preventive Services Task Force (USPSTF) recommendation against routine prostate cancer screening has resulted in a decrease in the number of PSA-based screenings ordered by physicians, with the greatest decline seen among urologists, according to findings of recently published study that one leading prostate cancer expert says raises more questions than it answers.

    The findings will be published in the June issue of The Journal of Urology; an uncorrected proof appears online ahead of print (Dec. 16, 2013).

    Researchers at Case Western Reserve University and University Hospitals Case Medical Center in Cleveland examined data for PSA tests performed at the medical center and its affiliated facilities from January 2008 to December 2012. During that period, 43,498 PSA screenings were performed, with the majority of the tests ordered by internal medicine (64.9%), followed by family medicine (23.7%), urology (6.1%), and hematology/oncology (1.3%). Screening numbers started to decline in 2009 with the release of the initial PSA screening trial results, and then continued to decline after the USPSTF recommendations were issued in 2012.

    To explore the specifics of the decline, investigators evaluated data reported for type of medical provider ordering the tests, as well as geographic location of the facility.

    “The recently published prostate screening trials and the USPSTF recommendations appear to have negatively impacted PSA screening,” said lead investigator Robert Abouassaly, MD, MSc. “These effects were more immediate and pronounced in the urban/academic setting, and more gradual in suburban and rural settings. Decreased prostate cancer screening was observed across all specialties over time, with, interestingly, the greatest impact seen among urologists.”

    Also somewhat surprising was the finding that, in terms of screening declines by patient age, the greatest decrease in screening was observed in the intermediate age group (50-59 years). Patients 60 years old or older also showed a decrease in PSA screening after the recommendation was released in May 2012, but this was nonsignificant.
