摘要:
目的 探讨微视频结合关键点指导对老年患者肠道准备的应用效果。 方法 选取2018年8—12月于蚌埠医学院第二附属医院行结肠镜检查的住院老年患者30例为对照组,2019年3—12月行结肠镜检查的住院老年患者30例为干预组,分别采用常规肠道准备健康指导、微视频结合关键点指导。运用渥太华肠道准备评分量表(Ottawa bowel preparation scale, OBPS)、肠道准备依从性量表进行调查,记录肠道准备期间不良反应的发生情况及检查过程中进镜时间。采用t检验分析比较2组患者OBPS得分和进镜时间;χ2检验分析比较2组患者肠道准备合格率、不良反应发生率、肠道准备依从性。 结果 干预组OBPS得分为(4.03±2.09)分,进镜时间为(7.20±1.48)min,均低于对照组OBPS得分(6.53±2.56)分和进镜时间(8.33±1.75)min(均P<0.05)。干预组不良反应发生率[13.3%(4/30)]低于对照组[46.7%(14/30),P<0.05],干预组肠道准备合格率[73.3%(22/30)]、饮食依从性[83.3%(25/30)]、服药依从性[80.0%(24/30)]、运动依从性[76.7%(23/30)]均高于对照组[36.7%(11/30)、26.7%(8/30)、36.7%(11/30)、30.0%(9/30)],差异有统计学意义(均P<0.05)。 结论 微视频结合关键点指导能有效提高肠道准备质量,值得临床推广实施。 Abstract:Objective To explore the application effect of micro-video combined with key point guidance on bowel preparation in elderly patients. Methods Thirty elderly patients who underwent colonoscopy from August to December 2018 in the Second Affiliated Hospital of Bengbu Medical College were selected as the control group, and 30 elderly patients who underwent colonoscopy from March to December 2019 were selected as the intervention group. Routine bowel preparation health guidance and micro-video combined with key point guidance were used, respectively. The Ottawa bowel preparation scale (OBPS) and bowel preparation compliance scale were used for investigation, and the occurrence of adverse reactions during bowel preparation and the time of entering the lens during the examination were recorded. T-test was used to analyse the differences in the OBPS score and the time of entering the lens between the two groups. Chi-square test was used to analyse the differences in the bowel preparation qualification rate, the incidence of adverse reactions and the bowel preparation compliance between the two groups. Results In the intervention group, the OBPS score was (4.03±2.09) points, and the time of entering the lens was (7.20±1.48) min, which were lower than the OBPS score (6.53±2.56) points and the time of entering the lens (8.33±1.75) min in the control group (all P < 0.05). The incidence of adverse reactions in the intervention group was 13.3% (4/30), which was lower than that in the control group [46.7% (14/30), P < 0.05]. In the intervention group, the qualified rate of bowel preparation [73.3% (22/30)], dietary compliance [83.3% (25/30)], medication compliance [80.0% (24/30)] and exercise compliance [76.7% (23/30)] were higher than those in the control group [36.7% (11/30), 26.7% (8/30), 36.7% (11/30) and 30.0% (9/30), respectively], and the differences were statistically significant (all P < 0.05). Conclusion Micro-video combined with key point guidance can improve the quality of bowel preparation, which is worthy of clinical promotion and implementation. -
