BACKGROUND: Rapid uptake of prostate-specific antigen (PSA) testing has occurred 
in the United States despite inconclusive evidence regarding mortality benefit.
METHODS: We examined data (n=927) from the 2003 Health Information National 
Trends Survey to assess prevalence of self-reported PSA use and its association 
with patients' decision making.
RESULTS: Over half (55.2%) the sample reported ever having had a PSA test. Men 
aged 65-74 (OR=2.53, 1.49-4.31), with some college (OR=2.41, 1.22-4.77) or 
college degrees (OR=5.01, 2.53-9.90) were more likely to have had PSA tests, 
while men without health insurance (OR=0.32, 0.12-0.88) or a usual source of 
care (OR=0.35, 0.22-0.54) were less likely. In a model including healthcare 
provider communication and information seeking, men who reported that providers 
involved them in decisions (OR=1.76, 1.02-3.03) and recommended PSA (OR=236.3, 
70.5-791.4) were more likely to have had the tests. Men aged 65-74 (OR=2.30, 
1.33-4.00), with college degrees (OR=2.91, 1.45-5.82), and greater information 
attention/seeking (OR=1.23, 1.07-1.40) were more likely to report PSA 
recommendations, while those without usual care were less likely (OR=0.37, 
0.22-0.64). Men without usual care (OR=0.38, 0.20-0.71) and Hispanic men 
(OR=0.40, 0.19-0.85) were less likely to report that healthcare providers 
involved them in healthcare decisions.
CONCLUSIONS: Results emphasize the relevance of patient decision making and the 
importance of healthcare providers in PSA testing.
