Purpose
Inadequate bowel preparation compromises the efficacy of colonoscopy. This study aimed to develop and evaluate a patient-tailored bowel preparation program designed to improve bowel preparation quality, medication adherence, and dietary adherence among patients undergoing colonoscopy.
Methods
The program consisted of four phases: (1) patient-specific assessment using a checklist; (2) personalized instructional videos; (3) short message service reminders; and (4) nurse-led counseling. A quasi-experimental, nonconcurrent nonequivalent control group, posttest-only design was used, with the control group recruited first. The study was conducted from April to July 2024 at a tertiary hospital in South Korea and included 80 adult outpatients scheduled for colonoscopy (40 control and 40 experimental participants). Outcomes included bowel preparation quality assessed using the Aronchick Bowel Preparation Scale, medication knowledge and adherence, and dietary knowledge and adherence.
Results
The experimental group demonstrated significantly higher bowel preparation quality than the control group (Z=8.13, p<.001, r=0.91). Medication knowledge and adherence were also significantly higher in the experimental group than in the control group (Z=3.54, p<.001, r=0.40; Z=6.50, p<.001, r=0.73; respectively). Similarly, dietary knowledge and adherence improved significantly in the experimental group compared with the control group (Z=5.28, p<.001, r=0.59; Z=5.32, p<.001, r=0.60; respectively).
Conclusion
The patient-tailored bowel preparation program effectively improved bowel preparation outcomes for colonoscopy. Future research should focus on integrating the program into electronic health records to enable automated delivery and improve efficiency and scalability in clinical practice.

Purpose
This study aimed to explore the roles, facilitators, barriers, and future directions of rapid response teams (RRTs) in Korean hospitals from the perspectives of both RRT and ward nurses.
Methods
Focus group interviews were conducted with 10 RRT nurses and 10 ward nurses across three hospitals that employed RRTs in Korea from August 2021 to February 2022. The interviews were recorded, transcribed, and analyzed using qualitative content analysis to identify themes relevant to RRT operations.
Results
The analysis yielded 10 subtopics and 4 main themes: the exploration of RRT's essential roles, the facilitators and barriers impacting RRT operations, and the construction of a blueprint for future systems. Notable barriers included unclear job assignments without legal safeguards, conflict arising from hierarchical structures, and insufficient organizational support. The following facilitators were identified: transformed perceptions through collaborative efforts, organizational recognition and support, and self-reinforcement by demonstrating expertise.
Conclusion
This study highlights the challenges and opportunities associated with implementing RRTs in Korean hospitals, including the need for clear role definitions, effective interprofessional collaboration, and organizational support. Based on these findings, future efforts should focus on establishing legal frameworks that define the scope of practice for RRT nurses.
