Despite the growing popularity of patient simulators as educational tools in the medical field, there is still scant empirical support delimiting their efficacy. A study by Radhakrishnan, Roche, & Cunningham (2007) set out to answer some of these questions by using the Clinical Simulation Evaluation Tool (CSET) to measuring specific nursing clinical practice parameters among a group of students who had been trained with the Human Patient Simulator (HPS). Five main areas of performance were measured: basic assessment skills, safety, prioritization, problem-focused assessment, ensuing interventions, delegation and communication in a complex two-patient, and simulated assignment. It was found that 'patient identification' and 'assessing vital signs' -belonging to the groups 'safety' and 'basic assessment skills', respectively- were both significantly better in the group which received additional HPS training with their clinical training.
