Comparing the effects of problem- and task-based learning on knowledge and clinical decision-making of nursing students concerning the use of transfusion medicine in pediatric nursing: An educational quasi-experimental study in Iran

Background: In the pediatric care field, ensuring safe and effective blood transfusions, promptly identifying adverse reactions, and implementing appropriate interventions are crucial. Therefore, undergraduate nursing curricula need to be structured to meet these professional standards and prepare nursing students, as future team members, to respond to relevant clinical situations. The objective of this study was to investigate how problem- and task-based learning affects knowledge and clinical decision-making of undergraduate nursing students concerning the use of transfusion medicine in pediatric nursing. Material and methods: This quasi-experimental study involved 82 nursing students recruited from two nursing schools in Iran using convenience sampling. Participants received educational content through either problem- (n = 40) or task-based learning (n = 42) methods. A researcher-made tool, comprising three parts and proven to be valid and reliable, was utilized for data collection. The tool was administered both before and immediately after the intervention. Data were analyzed using Wilcoxon rank-sum, Mann-Whitney U, Spearman's correlation and multivariate analysis of covariance tests via SPSS v16.0. A p-value of <0.05 was considered significant for all tests. Results: The median post-test knowledge and clinical decision-making scores within problem- and task-based learning groups were 62.68 vs. 74.65 and 53.33 vs. 76.67, respectively. Significant differences were observed between the mean pre- and post-test scores of both variables within both intervention groups (p < 0.05). Multivariate analysis of covariance revealed that task-based learning resulted in significant differences between the two groups in terms of knowledge (F = 87.9 %, p = 0.002, Eta2 = 0.114) and clinical decision-making (F = 99.9 %, p < 0.001, Eta2 = 0.271). Conclusions: Given the greater effectiveness of task-based learning, nursing schools are advised to utilize this method in undergraduate nursing curricula to ensure the adequacy of the clinical skills acquired by nursing students prior to graduation.
