Cost-Utility Analysis of Virtual and Mannequin-Based Simulation

Introduction The purposes of this study were to (1) compare learning outcomes between students who participated in mannequin-based simulation activities and students who participated in virtual simulation activities and (2) describe a cost-utility analysis comparing the two types of simulation activities in terms of costs and multiple measures of effectiveness. Methods Nursing student participants were randomly assigned to one of two experimental groups to complete either a mannequin-based or virtual simulation activity. The simulation scenario was the same for both groups and involved the care of a hospitalized patient experiencing a chronic obstructive pulmonary disease exacerbation. Participants completed presimulation and postsimulation assessments reflecting qualitative and quantitative measures of learning. A random sample of participants from each group completed a postsimulation performance assessment during which they interacted one on one with a standardized patient. Results Eighty-four nursing students were enrolled in the study and completed the simulation activities. There were no significant differences in quantitative measures of learning or performance between participants in the mannequin-based and virtual simulation groups. Participants' qualitative responses to postintervention written reflections and questions yielded additional data for describing learning from the two interventions. In the cost-utility analysis, the virtual simulation activity had a more favorable cost-utility ratio of US $1.08 versus the mannequin-based simulation activity's US $3.62. Conclusions Healthcare educators striving to make evidence-based decisions about how to best employ simulation pedagogy may consider these findings about the cost utility of various simulation modalities. However, additional research is needed.
