Abstract:
Objective
To evaluate the effect of evidence-based continuous quality improvement in enhancing the quality of bowel preparation for colonoscopy in hospitalized elderly patients.
Methods
Guided by the Continuous Quality Improvement (CQI) model developed by Fudan University, we conducted evidence acquisition through systematic retrieval and synthesis of evidence-based resources including evidence summaries, clinical practice guidelines, and systematic reviews related to colonoscopy and bowel preparation. Following a four-stage process comprising on-site audit, barrier analysis, strategy development, and outcome evaluation, we formulated best-practice evidence and implemented it among hospitalized elderly patients undergoing colonoscopy or related treatments. T test was used to compare the measurement data, χ2 test was used to compare the counting data.
Results
Ten evidence-based recommendations and 20 audit criteria were ultimately included. After implementing evidence-based practice, the Boston Bowel Preparation Scale (BBPS) scores improved from 5.83 ± 1.60 to 6.02 ± 0.82(t=1.430, P > 0.05), while the qualified rate of intestinal preparation significantly increased from 71.11%to 87.50% (χ2=7.675, P < 0.01). The risk assessment and education of intestinal preparation have both improved significantly: awareness of risk factors for adverse effects of bowel preparation rose from 16.67% to 100% (P < 0.01), proper assessment of these risk factors increased from 0 to 88.89% (P < 0.01),and utilization of diverse patient education methods improved from 0 to 100% (P < 0.01).
Conclusion
The evidence-based bowel preparation practice for hospitalized elderly patients significantly enhanced preparation adequacy rates and nursing adherence to best-practice guidelines.
