品管圈活动在降低结肠镜检查患者肠道准备不合格率中的应用

Application of quality control circle in colonoscopy inspectors in disqualification rate of reducing the bowel preparation

目的：探讨品管圈活动在降低门诊结肠镜检查患者肠道准备不合格率中的应用效果。方法成立品管圈小组，选定“降低门诊结肠镜检查患者肠道准备不合格率”为活动主题，按照品管圈活动步骤开展活动，分析导致肠道准备不合格的原因，针对原因拟定改进对策并予以实施。比较品管圈活动前后肠道准备不合格率。结果开展品管圈活动后门诊结肠镜检者肠道准备不合格率从39．09％降到14．03％，差异有统计学意义（χ2＝53．65，P ＜0．01）；目标达标率为104．42％，进步率为64．11％。结论品管圈活动能有效降低门诊结肠镜检查患者肠道准备不合格率，从而提高诊疗质量、并减轻患者经济负担。

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（ x2 = 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.
