Effects of Quality Control Circle Activities for Intravenous Cannula Placement Using Deming Cycle Management: A Case-Controlled Study

The present study aimed to explore the effectiveness of quality control circle (QCC) activities under the guidance of the Deming cycle Management for improving intravenous (IV) cannula placement. A total of 1,035 patients who underwent IV cannula placement from March 2019 to June 2019 in the Department of Hepatobiliary Surgery and Department of Renal and Thoracic Surgery of our hospital were enrolled as the control group, and 1,437 patients who underwent IV cannula placement in the same places as above but from July 2019 to December 2019 were enrolled as the test group. A between-group comparison was performed on intangible and tangible outcomes (duration of IV cannula placement, complications, patient awareness rate of maintenance knowledge of IV cannula, patient satisfaction rate with nursing staff, nurse skills in IV cannula infusion, and maintenance). After QCC activities were implemented, the scores of 11 QCC members in the five aspects of QCC technique application, communication and coordination, sense of responsibility and honor, motivation, and problem-solving ability all improved compared with those before the activities (p < 0.05), and the duration of IV cannula placement in the test group was 70.22 ±48.33 h, which was longer (p < 0.05) than the 60.59±41.9 h of the control group. The test group had a significantly lower (p < 0.05) rate of complications (12.9%, 12.6%, and 1.3% for extravasation, phlebitis, and cannula obstruction, respectively) than the control group (30.0%, 11.4%, and 4.1% for blood oozing, phlebitis, and cannula obstruction respectively); the patient awareness rate of maintenance knowledge of IV cannula and patient satisfaction rate with nursing staff in the test group were 90% and 96.3%, respectively, which were significantly higher (p < 0.05) than the 82.4% and 81.5% in the control group. The scores of nurse skills in IV cannula infusion and maintenance in the test group were 90.5 ±1.3 and 93.6 ±2.0, respectively, which were significantly higher (p < 0.05) than the 85.5 ±2.7 and 81 ±1.0 in the control group. The implementation of QCC activities under the guidance of the Deming cycle Management in IV cannula placement improves the ability of the department’s nursing team to identify, analyze, and solve problems, which is favorable for continuous improvement of nursing quality, leading to an elongated duration of IV cannula placement, reduced rate of complications, and improved patient satisfaction rate with nursing services.
