Evaluation of students’ clinical performance post-simulation training

Abstract

Introduction Traditionally in Australia, sonographer skills are learnt on patients in clinical practice. A four-year undergraduate-postgraduate course introduced ultrasound simulation to prepare novice sonographer students for interaction with patients. Second-year students learnt psychomotor and patient-sonographer communication skills during simulation using commercial ultrasound machines and volunteer year-group peers as standardised patients. This paper reports on the transfer of the ultrasound skills learnt in simulation to clinical practice. Methods Clinical performance evaluations were completed by 94 supervisors involved in the initial clinical practice of 174 post-simulation second-year students over a two-year period (2015–2016). Student performance of each component skill, and skill category, was analysed by modelling binomial proportions with logistic regression. Results Students demonstrated substantial transfer of learnt ultrasound skills to achieve a mean of advanced beginner competence (mean score of equal to or >3/5) in complex psychomotor and patient-sonographer communication skills, as measured one month into clinical practice. Knowledge and skill components, or sub-tasks, varied significantly (P < 0.001) in transferability. Scanning tasks in general, particularly the skill of ‘extending the examination’, transferred with significantly (P < 0.001) less efficacy than pre-exam, instrumentation, post-exam, and additional tasks. Skill transfer improved significantly (P < 0.001) following increased deliberate practice with tutor feedback. Conclusion Preclinical simulation, using standardised patients, clearly stated objectives to manage cognitive load and immediate tutor feedback, facilitated substantial transfer of ultrasound skills to clinical practice. The efficacy of skill transfer varied but improved with increased deliberate practice and feedback quality. Implications for practice The incorporation of preclinical simulation into the core curriculum of sonographer courses is recommended to improve student performance, reduce the burden on clinical staff and increase patient safety during the early stages of ultrasound education.
