Impact of scenario validity and group size on learning outcomes in high-fidelity simulation: A systematics review and...

To determine the effects related to scenario validity and group size in high-fidelity simulation among undergraduate nursing students.

A systematic review and meta-analysis of randomized controlled trials and quasi-experiment.

Embase, PubMed, Web of Science, Wangfang database, and Cochrane Library, China National Knowledge Infrastructure were searched from the start of each database to February 22, 2022. The references and citations lists were manually screened to find additional references.

Screening and quality assessment of the retrieved studies were conducted independently by two authors. Discussions with a third author sorted out any discrepancies between the two authors. Using meta-analysis procedures based on a random-effect model, outcome data were synthesized and standard mean difference was computed with a 95 % confidence interval.

Thirty-three studies were included. A total 4077 undergraduate nursing students were recruited, of which 2068 participated in experimental groups. High-fidelity simulation with scenario validity was better than high-fidelity simulation without scenario validity in cultivating undergraduate nursing students' knowledge (p = 0.03), and they were equivalent in improving students' skills (p = 0.75). Groups of six or fewer students in each high-fidelity simulation tend to be more effective at promoting knowledge (standard mean difference = 0.98) and skill (standard mean difference = 1.00), but the differences were not statistically significant.

High-fidelity simulation with scenario validity and with less than six students in each group can be more effective in cultivating knowledge and skills among undergraduate nursing students. For high-fidelity simulation to be as effective as possible, nursing instructors should ensure scenario validity and limit the number of students in each group to under six.
