Background and Aims. Inpatients’ bowel preparation before colonoscopy is frequently inadequate, and various interventions have been investigated to improve it, so far. We aimed to evaluate the efficacy of various interventions to improve inpatients’ colon preparation quality. Methods. We systematically reviewed the literature for publications on interventions aiming to improve the quality of inpatients’ colon preparation until June, 2018. Significant heterogeneity—measured with —was detected at the level of . Adequacy rates were measured using inverse variance, and the size effect of different interventions was calculated using random effects model and expressed as odds ratio (OR). Results. Seventeen studies enrolling 2733 inpatients were included. Overall, 67% (60-75%) of the participants achieved adequate colon cleansing (; ). In six studies assessing the impact of educational interventions to patient/physician/nurse vs. no intervention, adequate bowel preparation was achieved in 77% (62-91%) vs. 50% (32-68%) of the patients (OR (1.67-7.28), ; ; ). Ten studies examined variations (qualitative and/or quantitative) in bowel preparation regimens with adequate preparation detected in 71% (60-81%) of the participants, and a single study examined the administration of preparation through an esophagogastroduodenoscope, resulting in adequate prep in 71% of the patients. Conclusions. Despite several interventions, only two-thirds of inpatients achieve adequate colon preparation before colonoscopy. Educational interventions significantly improve inpatients’ bowel preparation quality.

提高住院患者结肠镜检查肠道准备质量的策略：系统评价和荟萃分析。

背景和目标。住院患者在结肠镜检查前的肠道准备通常不充分，到目前为止，已经研究了各种干预措施来改善它。我们旨在评估各种干预措施对提高住院患者结肠准备质量的效果。方法。我们系统地回顾了有关干预措施的文献，旨在提高住院患者结肠准备的质量，直至 2018 年 6 月。. 使用逆方差测量充分率，使用随机效应模型计算不同干预措施的大小效应并表示为优势比（OR）。结果。纳入了 17 项研究，招募了 2733 名住院患者。总体而言，67% (60-75%) 的参与者实现了充分的结肠清洁 (; ）。在评估教育干预对患者/医生/护士与不干预的影响的六项研究中，77% (62-91%) 与 50% (32-68%) 的患者（或(1.67-7.28),; ; ）。10 项研究检查了肠道准备方案的变化（定性和/或定量），在 71% (60-81%) 的参与者中检测到了充分的准备，一项研究通过食管胃十二指肠镜检查了准备的管理，导致在71%的患者。结论。尽管进行了几次干预，但只有三分之二的住院患者在结肠镜检查前完成了充分的结肠准备。教育干预显着提高了住院患者的肠道准备质量。
