RESUMEN
Objective To investigate the application of quality control cycle activity in reducing thedisquali-fication rate of bowel preparation for colonoscopy outpatients.Methods Set up a group of quality control circle,and select the issues that reducing the disqualification rate of bowel preparation for colonoscopy outpatients as the activity theme.According to the activity steps of quality control circle,the activity was carried out.The causes of disqualifica-tion rate of bowel preparation were analyzed and the countermeasures to improve and implement were implemented. Also,the disqualification rates of bowel preparation before and after quality control circle were compared.Results The disqualification rate of bowel preparation was reduced from 39.09% to 14.03% after quality control circle activi-ty.The difference was statistically significant(χ2 =53.65,P <0.01).Target success rate was 104.42%,and the pro-gress rate was 64.11%.Conclusion The quality control circle activity can effectively reduce the disqualification rate of bowel preparation for colonoscopy outpatients,thereby improve the quality of diagnosis and treatment,and reduce the economic burden of patients.After clear improvement of focus,the leading causes of disqualification bowel prepa-ration are obtained through characteristic diagram (figure 2)analysis.Also,true causes are validated based on the three principles.The four true causes final defined include short contact time nurses and patients,large liquid dosage, none nursing intervention outside hospital,and chronic constipation without intervention.
