Objective To construct the key-point guidelines of bowel preparation for elderly patients with colonoscopy. Methods The guidelines were made based on literature review,theoretical analysis,qualitative interview.Then they were determined by 14 clinical nurse specialists, nursing education experts and medical experts from 6 provinces or cities through two rounds of expert consultations. Results The response rate of two rounds'questionnaire was 100.00%. The authority of experts coefficient in the two rounds were 0.89. The coefficients of variation of the first and second rounds were respectively 0.07~0.27 and 0.05~0.13. The coordination coefficients for the 2 rounds were 0.377 and 0.404 respectively (Χ2=105.473 and 124.307,P<0.001).In the first round,the average of the importance rating was 3.50~4.95, with a standard deviation of 0.35~0.95.In the second round,the average of the importance rating was 4.71~4.93,with a standard deviation of 0.27~0.61.The key-point guidelines of bowel preparation included 3 key points for bowel preparation, 4 key moments,7 key guidance contents, 4 criteria for the process of bowel preparation and the corresponding remedial measures. Conclusion This study established the key-point guidelines of bowel preparation for elderly patientsand the degree of enthusiasm,authority,coordination and concentration of the experts was high so as to provide a reference for the clinical implementation of standardized bowel preparation guidance.%目的 探讨构建老年结肠镜检查患者的肠道准备关键点指导方案.方法 以理论分析、文献回顾、质性访谈为基础,选择全国7个省市临床护理、护理教育、医疗专家3个领域的14名专家采用德尔菲法(Delphi)对该方案进行2轮专家咨询,最终确立老年结肠镜检查患者肠道准备关键点指导方案表.结果 两轮专家函询表有效回收率均为100.00%;两轮专家的权威程度系数均为0.89;第一轮与第二轮各条目的变异系数分别为0.07~0.27与0.05~0.13;Kendall's 协调系数分别为0.377和0.404(Χ2值分别为105.473和124.307,均 P<0.001);第一轮函询各条目的重要性均数为3.50~4.95,标准差为0.35~0.95,第二轮函询各条目的重要性均数为4.71~4.93,标准差为0.27~0.61.老年结肠镜检查患者肠道准备关键点指导方案包括3个肠道准备关键点,4个关键指导时机,7项关键指导内容,4项肠道准备判断标准及4项对应的补救措施.结论 本研究构建了老年结肠镜检查患者肠道准备关键点指导方案,经统计分析咨询结果可靠,专家的积极程度、权威程度、协调程度及集中程度均较高,能为临床开展规范化的肠道准备指导工作提供参考.
