Objective To investigate the improvement by QCC on sending rate of stool /urine from cancer patients. Methods We carried out a process named "the neat ring" quality circles. In the process we tried to enhance the pa-tients’ specimen sending rate of stool/urine by quality control. We internalized inpatients who were hospitalized in our department in a certain month before and after QCC had been implemented, analyzed their stool /urine sending rate on the third day after their admission and the day when they left the hospital. Results The stool sending rate on corre-sponding dates increased from 33.33% and 62.86% to 74.04% and 96.15%,as to urine, the sending rate augmented from 38.89%and 64.81%to 95.45%and 100%respectively. All differences were statically significant(P<0.01). Con-clusion The specimen sending rate of stool /urine from cancer inpatients were substantially enhanced through the im-plement of QCC.
