Variations in the Diagnostic Process among Urologists in One Region Recorded Using an Interactive Computer Program

Abstract

To analyse how male cases suffering from lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) are handled within a well-defined health-care region in Scandinavia, an interactive computer program containing 20 cases suffering from LUTS due to BPH was used for recording the diagnostic process and the treatment decisions; 37 out of a total of 50 urologists practicing within a small health region participated. The diagnostic process varied considerably due to a varying choice of diagnostic tests and the large differences in interpreting the qualities described by the tests. The probability that a patient would be offered a treatment within the region was analysed. For many patients the probability that a treatment was chosen was in the vicinity of 50%. No treatment probability was correlated to the symptom score of the patients. While the probability that a transurethral prostatic resection would be offered to the patients within the region was correlated significantly to urodynamic variables, residual urine and to cystoscopy findings, the probability that transurethral microwave or finasteride therapy would be offered was not correlated to any of the described qualities. The costs of the diagnostic process in all the patients incurred by each of the urologists varied by up to 500%. It was estimated that approximately 40% of the costs involved diagnostic tests that did not influence the decision to offer or not to offer treatment. In conclusion, the enormous variations in the handling of the cases recorded in the study stress the need that a management formula should be used in the handling of patients with LUTS.
