Impact of a Structured Training Program on Medical Student Confidence and Behavior During Their First Radial Arterial...

Area of Science:

• Medical Education
• Clinical Skills Training
• Patient Safety

Background:

• Radial artery puncture is crucial for gas exchange assessment but often stressful for inexperienced operators.
• Formal training for this procedure is inconsistently integrated into medical curricula.
• Student anxiety and patient pain are significant concerns during arterial punctures.

Purpose of the Study:

• To evaluate the impact of structured simulation-based training on medical students' anxiety, confidence, and technical performance during their first arterial puncture.
• To assess the influence of training on patient experience, including pain and apprehension.
• To determine if structured training affects decision-making regarding local anesthesia use.

Main Methods:

• Third-year medical students with no prior arterial puncture experience were randomized into a structured training group or a control group.
• Participants completed questionnaires on apprehension, satisfaction, and confidence post-procedure.
• Data collected included local anesthesia use, first-attempt success rates, and patient-reported pain and apprehension.

Main Results:

• Self-reported apprehension and confidence levels were similar between groups.
• Trained students were significantly less likely to use local anesthesia (35% vs. 77.8%), suggesting increased procedural confidence.
• First-attempt success rates were comparable (23.1% vs. 48.3%); patient-reported pain was not statistically different.

Conclusions:

• Structured training positively influenced student behavior, reducing reliance on anesthesia despite similar self-reported confidence.
• Behavioral indicators suggest improved self-efficacy and readiness for clinical performance following structured procedural education.
• Findings support the value of structured procedural training and highlight the need for validated assessment tools and long-term follow-up.
