There is inconclusive evidence that prostate cancer screening with prostate-specific antigen (PSA) reduces mortality. Although PSA testing is widespread, it is unknown how many physicians have taken the PSA test themselves.
To determine the prevalence of PSA testing among physicians.
Cross-sectional survey.
A nationwide stratified random sample of urologists (response rate 61%, n=247), Internists (response rate 51%, n=273), and family physicians (response rate 64%, n=249) were surveyed by mail in 2000. After excluding female respondents and men who either reported a positive history of prostate cancer or did not respond to that query, there were 146 urologists, 96 Internists, and 118 family physicians.
Whether physicians had undergone prostate cancer screening with PSA.
Eighty-seven percent (155/178) of male physicians aged, 50 and older and 21% (31/150) of white male physicians under age 50 reported having had a PSA test. More urologists than nonurologists in both age groups reported having had a screening PSA test.
Most physicians aged 50 and older report undergoing PSA testing. This may reflect a belief in its efficacy and contribute to its widespread use.
关于前列腺特异性抗原（PSA）筛查前列腺癌能否降低死亡率，证据尚无定论。尽管PSA检测广泛应用，但不清楚有多少医生自己进行过PSA检测。
确定医生中PSA检测的普及率。
横断面调查。
2000年通过邮件对泌尿科医生（回复率61%，n = 247）、内科医生（回复率51%，n = 273）和家庭医生（回复率64%，n = 249）进行了全国分层随机抽样调查。排除女性受访者以及报告有前列腺癌阳性病史或未回复该问题的男性后，有146名泌尿科医生、96名内科医生和118名家庭医生。
医生是否接受过PSA前列腺癌筛查。
50岁及以上男性医生中有87%（155/178），50岁以下白人男性医生中有21%（31/150）报告进行过PSA检测。两个年龄组中，报告进行过PSA筛查检测的泌尿科医生都多于非泌尿科医生。
大多数50岁及以上的医生报告进行过PSA检测。这可能反映出他们相信其有效性，并促使其广泛应用。
