Purpose: Conventional methods to describe the severity of a patient’s hematuria following urological procedure often produce varying results amongst medical practitioners. We developed the six-color color card system to improve the consistency of interpretation of the severity of patient’s blood in urine following urological surgery.

Material and Methods: A total 10 physicians and 10 nurses were invited to participate in this study. In contrast to the conventional color scale (which uses the 5-color grading system of: clear, pink, watermelon juice, tomato juice and blood-like), we choose 6 different degrees of redness from the international color grading system (from clear to dark red color) for medical staffs to utilize as a descriptive reference. The primary observation recorded was the color description from the most participants. The secondary observation recorded was the number of times there was an inconsistent count. The inconsistent counts from the six-color color card and conventional methods were compared.

Results: The average inconsistent counts are 0.34 (SD 0.557) and 1.92 (SD 1.426) for color card method and conventional method, respectively. Using t-test to calculate the statistical significance and get p value < 0.0001 (two-tail).

Conclusions: Using the color card interpretation method may help improve the accuracy and consistency while communicating the severity of the patient’s post-procedure hematuria amongst physicians and nurses.
