ObjectiveTo investigate the efficacy of Quality Control Circles (QCC) in reducing the emergency application times of maintenance hemodialysis. MethodsIn December, 2012, the quality circle was formed by eight nurses and a physician, through brainstorming. The group finally selected "Reducing emergency maintenance dialysis times" as the theme. With the help of questionnaire, interview, and comparative study, we analyzed the emergency situation of maintenance hemodialysis patients, and regulate and implement related policies. ResultsBy QCC practices, the times of hemodialysis declined from 11.7 to 5.3 cases per month, which exceeded our expectations largely. As to the circle members, their problem-solving skills, responsibility, communication skills, self-confidence, motivation and QCC techniques were also improved. ConclusionQCC can not only reduce the times of maintenance dialysis, but also improve the team cohesion, harmony and quality management capabilities.
