Teaching nursing students: As an umbrella review of the effectiveness of using high-fidelity simulation

To conduct an umbrella review of the effectiveness of using high-fidelity simulation in nursing student teaching, thereby supporting continuous improvement in teaching practitioners' implementation of high-fidelity simulation intervention strategies. Several systematic reviews have investigated the effectiveness of high-fidelity simulation in nursing student teaching in recent years. However, conclusions vary and a systematic assessment is lacking. This review encompasses an umbrella review. A search of PubMed, Embase, Cochrane Library, Web of Science and OVID databases was conducted to retrieve data on an umbrella review of high-fidelity simulation effectiveness in nursing student teaching from database inception to November 2023. The quality of the included systematic reviews was independently assessed by two reviewers using the AMSTAR 2 and PRISMA scales. Outcome indicators from the included systematic reviews were graded using the GRADE system. Twelve systematic reviews focusing on high-fidelity simulation effectiveness in nursing student teaching were included. Notably, all 12 systematic reviews exhibited very-low methodological quality, with 9 exhibiting some degree of reporting deficiencies, 2 exhibiting severe information deficiencies and 1 reporting relatively complete information. A total of 22 outcome indicators and 53 pieces of evidence were included. The results revealed 15 pieces of low-quality evidence and 38 pieces of very-low-quality evidence. Mounting evidence suggests that high-fidelity simulation teaching effectively enhances nursing students' theoretical performance, practical skills and various clinical comprehensive abilities, highlighting a positive teaching effect. However, further validation through high-quality, large-sample studies is warranted. The overall evidence quality of the current systematic reviews evaluating high-fidelity simulation effectiveness in nursing student teaching is low. Additionally, the methodological quality and the degree of reporting standardization require further improvement. Therefore, high-quality, large-sample randomized controlled trials are essential for further substantiating high-fidelity simulation effectiveness in nursing student teaching.
