Background:
Anxiety is a common and significant problem in patients who need to undergo colonoscopy. However, the question of which non-pharmacological intervention is the best strategy to reduce anxiety in patients undergoing colonoscopy remains unanswered.
Objectives:
To evaluate and rank the effectiveness of various non-pharmacological interventions for reducing anxiety in patients undergoing colonoscopy in order to identify the most effective strategies.
Methods:
We searched PubMed, Cochrane Library, Embase, Web of Science, and Medline for randomized controlled trials published from the database construction to March 2024. The primary outcome was the difference between pre- and post-intervention anxiety means. A network meta-analysis was conducted utilizing the "gemtc" package based on R4.3.0.
Results:
The analysis encompassed 24 randomized controlled trials, incorporating 2525 participants and evaluating 9 non-pharmacological interventions. All non-pharmacological interventions reduced anxiety in patients undergoing colonoscopy compared to standard care, with music intervention (SMD = -0.52, 95 %CI (-0.84,-0.20)), audiovisual distraction (SMD = -0.54, 95 %CI(-0.96,-0.12)), video information (SMD = -1.47, 95 %CI(-2.03,-0.90)), individual education (SMD = -1.72, 95 %CI(-2.76,-0.70)), and electroacupuncture (SMD = -1.12, 95 %CI(-2.10,-0.13)) having statistically significant effects. SUCRA ranking identified the priority of individual education (SUCRA: 92.5 %) and video information (SUCRA: 87.7 %). Meta-regression and sensitivity analysis further demonstrated the stability of the evidence. The certainty of the evidence was mostly rated as medium to low.
Conclusion:
This review highlights the superior effects of individual education and video information in reducing anxiety in patients undergoing colonoscopy. The findings of our review could provide clinical decision-makers and healthcare practitioners, such as doctors and nurses, with evidence-based practices for selecting interventions to reduce anxiety in patients undergoing colonoscopy.
