Prostate-specific antigen (PSA) testing has increased in several countries. There is incomplete knowledge of PSA testing patterns.
Determine the prevalence of PSA testing and explore patterns of PSA retesting in Stockholm County, Sweden.
A population-based study was performed. Through registry linkages, we collected population information, data on PSA tests, pathology reports, and clinical information. The study population comprised males living in Stockholm County in 2011 (n=1034129), of which 229 872 had a PSA test during the period 2003-2011.
We determined limited-duration-point prevalence of PSA testing and performed survival analysis on PSA retesting for men aged 40-89 yr.
The number of PSA tests increased from 54239 in 2003 to 124613 in 2011. During the 9-yr study period, 46%, 68%, and 77% of men without a prior prostate cancer (PCa) diagnosis and aged 50-59 yr, 60-69 yr, and 70-79 yr, respectively, had a PSA test. During 2010 and 2011, 25%, 40%, and 46% of men aged 50-59 yr, 60-69 yr, and 70-79 yr, respectively, had a PSA test. The prevalence of PSA testing increased from 2003 to 2011. The probability of retesting was PSA and age dependent, with a 26-mo cumulative incidence of 0.337 (95% confidence interval, 0.333-0.341) if the first PSA value was
