Criteria for errors in prostate-specific antigen diagnostics.
Summary of "Criteria for errors in prostate-specific antigen diagnostics."
BACKGROUND:
The widespread use of prostate-specific antigen (PSA) determination in the diagnosis of prostate cancer has proved to be generally beneficial; however, as a result expert commissions, arbitration committees and the courts have had to deal with an increased number of suspected treatment errors. As a follow-up to the previous report on the decisions made by expert commissions, this paper deals with recent developments and their assessment.
METHODS:
The procedures followed for assessment have been extensively described in the previous paper. The criteria for assessment of disputed treatment were and are the accepted standards (i.e. the standards applicable to medical specialists) and the quality of care applied in accordance with the pertinent definitions.
RESULTS:
In the period from 2005 to 2011 (i.e. 7 years) errors in medical treatment were determined in connection with PSA determinations in 22 out of the 37 cases reviewed, i.e. 71%. These were subdivided into 3 cases from general practitioners, 5 cases from specialists in internal medicine and 15 cases from urologists (in 1 case 2 different doctors were involved). They were faulted for omitting a follow-up biopsy of the prostate. In 12 cases this involved PSA values above the recommended cut-off level without suspicious palpation results, in 7 cases raised PSA levels with suspicious palpation findings, in 2 cases suspicious palpation findings without raised PSA and in 1 case the omission of both palpation and PSA determination. An error in treatment was negated if the PSA value was below the recommended cut-off value or had fallen below it again subsequently (two cases each), if follow-up prostate biopsy was recommended and documented following the determination of raised PSA and/or suspicious palpation findings (three cases) or if follow-up treatment was rejected in spite of a documented recommendation (one case).
CONCLUSIONS:
Treatment errors in association with PSA determinations can therefore be uniformly and plausibly assessed using objective criteria and can thus be avoided.

Medical and Biotech [MESH] Definitions
Prostatic Secretory Proteins
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
Prostate-specific Antigen
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
Seminal Plasma Proteins
Proteins found in SEMEN. Major seminal plasma proteins are secretory proteins from the male sex accessory glands, such as the SEMINAL VESICLES and the PROSTATE. They include the seminal vesicle-specific antigen, an ejaculate clotting protein; and the PROSTATE-SPECIFIC ANTIGEN, a protease and an esterase.
Tissue Kallikreins
A family of trypsin-like SERINE ENDOPEPTIDASES that are expressed in a variety of cell types including human prostate epithelial cells. They are formed from tissue prokallikrein by action with TRYPSIN. They are highly similar to PROSTATE-SPECIFIC ANTIGEN. EC 3.4.21.35.
Medical Errors
Errors or mistakes committed by health professionals which result in harm to the patient. They include errors in diagnosis (DIAGNOSTIC ERRORS), errors in the administration of drugs and other medications (MEDICATION ERRORS), errors in the performance of surgical procedures, in the use of other types of therapy, in the use of equipment, and in the interpretation of laboratory findings. Medical errors are differentiated from MALPRACTICE in that the former are regarded as honest mistakes or accidents while the latter is the result of negligence, reprehensible ignorance, or criminal intent.
