Exploring the experiences of sonography students with simulation-based learning: A perspective from South Africa

INTRODUCTION

Simulation-based learning (SBL) is widely used in healthcare education to provide a safe environment for students to practice clinical scenarios without causing patient harm. While established in developed countries, SBL's implementation is new in South Africa; there is a lack of research addressing sonography students' experiences. This study aimed to explore and describe the experiences of Bachelor of Science (BSc) second-year sonography students using SBL for clinical training at a local University of Technology (UoT).

METHOD

An exploratory, qualitative and descriptive research study was conducted in 2020, with virtual one-on-one interviews due to COVID-19 restrictions. Eight BSc second-year sonography students, who had undergone SBL in their first year, participated. Data saturation was achieved, and interviews were audio recorded and transcribed verbatim.

RESULTS

Thematic analysis revealed three themes: (1) Enhancing preparedness for the clinical environment, (2) Limitations of the tissue-equivalent phantom and (3) Suggestions for improving simulation. While students expressed positive feedback and enjoyment of the simulation tool, they also highlighted limitations, such as unrealistic representations of real patient scanning conditions.

CONCLUSION

This study provides valuable insights into sonography students' experiences with SBL. Positive influence of SBL on clinical training was observed. To enhance SBL for future sonography students, consideration for high-fidelity simulators with advanced software is recommended. Funding options to invest in such simulators should be explored by radiography educators to promote more realistic training experiences.

Evaluation of students' clinical performance post-simulation training

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.
