OBJECTIVE: Measurement of prostate-specific antigen (PSA) is not only used as a screening instrument by urologists, but also by general practitioners and internal specialists (GP-IS).
Until now, there are neither data on the approach of German GP-IS in practicing this nor have data been classified in the context of available international literature on this topic.
MATERIALS AND METHODS: Between May and December 2012, a questionnaire containing 16 items was sent to 600 GP-IS in Brandenburg and Berlin. The response rate was 65 % (392/600). Six indicator questions (IQ1-6) were selected and results were set in the context of available international data. The quality of present studies was evaluated by the Harden criteria.
RESULTS: Of the 392 responding physicians, 317 (81 %) declared that they would use PSA testing for early detection of PCA (IQ1) and, thus, formed the study group. Of these GP-IS, 38 % consider an age between 41 and 50 years as suitable for testing begin (IQ2), while 53 % and 14 % of the GP-IS perform early detection until the age of 80 and 90 years, respectively (IQ3). A rigid PSA cut-off of 4 ng/ml is considered to be reasonable by 47 % of the involved GP-IS, whereas 16 % prefer an age-adjusted PSA cut-off (IQ4). Patients with pathological PSA levels were immediately referred to a board-certified urologist by 69 % of the GP-IS. On the other hand, 10 % first would independently control elevated PSA levels themselves after 3-12 months (IQ5). Furthermore, 14 % of the interviewed physicians consider a decrease of PCA-specific mortality by PSA screening as being proven (IQ6). Knowledge regarding PCA diagnostics is mainly based on continuous medical education for GP-IS (33 %), personal contact with urologists (6 %), and guideline studies (4 %). While 53 % indicated more than one education source, 4 % did not obtain any PCA-specific training. The results provided by this questionnaire evaluating response of German GP-IS to six selected indicator questions fit well into the international context; however, further studies with sufficient methodical quality are required.
CONCLUSIONS: Despite current findings and controversial recommendations of the two large PCA screening studies on this issue, German GP-IS still frequently use PCA screening by PSA measurement. Primary strategies of early detection as well as follow-up after assessment of pathologically elevated PSA levels poorly follow international recommendations. Thus, an intensification of specific education is justified.
