ObjectiveTo evaluate application effectiveness of  quality control circle (QCC) in increasing the face mask wearing rate of hospitalized pulmonary tuberculosis (TB) patients.MethodsNine nurses in department of tuberculosis formed a ‘circle’,   the  theme of ‘improving the face mask wearing rate of hospitalized pulmonary TB patients’ was established, rectification measures were formulated and implemented, face mask wearing rates of patients before and after implementing QCC activities were analyzed statistically.ResultsThe face mask wearing rate of hospitalized pulmonary TB  patients after implementing  QCC activities  was higher than that before implementing  QCC activities (87.50% ［147/168］ vs 65.54%［116/177］, P<0.05). The abilities of every ‘circle member’ have been improved in the following aspects: problemsolving skills, sense of responsibility, communication skills, selfconfidence, team working, enthusiasm, qualitycontrol techniques, and cooperation abilities,the total average score increased from 23.78 before implementing QCC to 33.78 after implementing QCC.ConclusionQCC activities can not only improve the face mask wearing rate of hospitalized pulmonary TB patients, but also enhance circle members’ qualitycontrol skills and team spirit.
