Effectiveness of simulation-based interventions at improving empathy among healthcare students: A systematic review and meta-analysis

Abstract

Objective: To examine the effectiveness of simulation-based interventions in improving empathy among healthcare students.

Design: A systematic review and meta-analysis of randomized controlled trials and clinical controlled trials.

Data sources: Studies in English language were sourced from seven electronic databases (PubMed, Embase, CINAHL, PsycINFO, Web of Science, Scopus and ProQuest Dissertations & Theses Global) from their respective inception dates until October 2020.

Review methods: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Random-effect meta-analyses were conducted. Heterogeneity was assessed using the I² statistics and Cochran's Q chi-squared test. Quality appraisal was conducted using the Cochrane risk of bias tool and the Grades of Recommendation, Assessment, Development, and Evaluation approach. Publication bias was assessed using funnel plots.

Results: Sixteen studies were included in this review. Meta-analysis reported statistically significant small, medium and very large effect sizes for empathy reported by healthcare students (SMD = 0.46, 95% CI: 0.25 to 0.66), simulated patients (SMD = 0.65, 95% CI: 0.41 to 0.89) and other personnel (independent observers, faculty members and examiners) (SMD = 1.27, 95% CI: 0.64 to 1.90) respectively, showing the effectiveness of simulation-based interventions in improving empathy among healthcare students. Subgroup analyses found that role-play was more effective than simulated patient and disease-state simulations. Multi-sessional interventions conducted for up to seven months and group-based simulation delivery were found to be more effective.

Conclusion: Educational institutions should conduct regular simulation-based interventions to continuously develop healthcare students' empathy during their academic journey. Future trials should involve students from more diverse healthcare disciplines. Empathy should be measured in a standardized manner and rely less on self-reported measures. Role-play segments and group-based simulations could be added to increase interventions' effectiveness. Studies should conduct longer follow-up assessments to determine the sustainability of students' empathy following intervention. Future research is needed to corroborate the current findings.
