To explore the effect of quality control circle activities in improving the detection rate of prostate cancer by puncture biopsy.

The Department of Ultrasound, Yinzhou Second Hospital carried out quality control circle activities from April to September 2022, with the theme of "multidisciplinary joint improvement of prostate cancer detection rate by puncture biopsy". The data of 60 patients who underwent prostate puncture from April 11, 2022 to April 22, 2022 were collected to analyze the main reasons affecting the prostate cancer detection rate by puncture biopsy, discuss and formulate corresponding countermeasures, and implement the formulated countermeasures. The data of 60 patients who underwent prostate puncture from August 1, 2022 to August 14, 2022 were collected to confirm the effect, calculate the goal achievement rate and progress rate, and standardize and continue to implement the countermeasures. The data of patients who underwent prostate puncture before (March 1 to March 31, 2022) and within one month after the implementation of the quality control circle activities (October 1 to October 30, 2022) were collected to calculate the detection rate of prostate cancer, and the χ² test was used to compare the changes in the prostate cancer detection rate by puncture biopsy between before and after implementing the quality control circle activities.

After the implementation of the countermeasures, the goal achievement rate was 107.3%, and the progress rate was 65.3%. The total number of punctures in one month after the implementation of the quality control circle activities was 141, including 76 cases of prostate cancer diagnosed by puncture pathology, and the puncture detection rate of prostate cancer was 53.9%. The total number of punctures in the month before the implementation of the quality control circle activities was 154, including 42 cases of prostate cancer diagnosed by puncture pathology, and the detection rate of prostate cancer was 27.3%. The difference in the detection rate of prostate cancer was statistically significant between before and after implementing the quality control circle activities (χ²=21.746, P<0.001).

Quality control circle activities have been carried out to standardize the operation process of prostate puncture, and the detection rate of prostate cancer by puncture biopsy has been effectively improved.
