To explore the effects of project-achieving quality control circle (QCC) in day surgery nursing optimization model so as to provide a theoretical support for hospital day surgery nursing management and process improvement.

A total of 119 patients with day surgery in April 2018 and 170 in November 2018 at Ningbo First Hospital of Zhejiang Province were selected as subjects. This study developed activities based on the QCC activity theme of "Construction of Day Surgery Nursing Management Model by Various Measures", plan-do-check-action (PDCA) cycle and 10 steps of project-achieving QCC. Before and after optimizing process, the field follow-up for patients was carried out by telephone follow-up and questionnaire investigation, and tangible results (satisfaction of pre-hospital service, completion rate of follow-up, score of patients' continuous nursing needs, satisfaction with day surgery) as well as intangible results (skill application, teamwork, communication and coordination, computer application, activity confidence and activity participation) were evaluated.

Patient's satisfaction of pre-hospital service raised from 52.1% to 82.4% before and after optimizing process; the rate of follow-up increased from 35.3% to 97.0%; patient's satisfaction with day surgery raised from 40.3% to 82.9%; the score of continuous nursing needs decreased from (20.90±12.91) to (17.59±11.78) ; the differences were all statistically significant (P<0.05) . The intangible results also improved, such as skill application of members in QCC.

The project-achieving QCC based day surgery nursing optimization model improves the completion rate of follow-up in nurses and patient satisfaction, and lowers patients' needs for continuous nursing and increases nursing team cohesion.
