Simulator-Based Training Sustainably Improves Confidence, Theoretical Knowledge, and Success Rates in Lumbar Puncture...

Area of Science:

• Medical Education
• Surgical Simulation
• Neuropsychiatric Practice

Background:

• Lumbar puncture (LP) is a critical clinical procedure in neuropsychiatry.
• Junior doctors experience significant stress and anxiety during LP, potentially impacting patient care.
• Current medical training often lacks innovative methods for LP, despite available simulators.

Purpose of the Study:

• To evaluate the effectiveness of simulator-based training for lumbar puncture (LP) compared to traditional methods.
• To assess the impact of simulation training on medical students' confidence, knowledge, and practical skills in performing LPs.
• To determine if enhanced training improves the success rate of initial LPs and patient safety.

Main Methods:

• A prospective case-control study involving undergraduate medical students.
• The "tutorial group" (n=20) received simulator-based LP training.
• The "control group" (n=21) received standard clinical instruction.
• Data collected included questionnaires on confidence and knowledge, and measurement of initial LP success rates.

Main Results:

• The tutorial group showed significantly higher success rates in their first 4 LPs (median 3 vs. 1, p < 0.001).
• Students in the tutorial group reported significantly higher confidence and safety in handling puncture needles.
• Enhanced knowledge of theoretical aspects was also noted in the tutorial group.
• Confidence and safety were strongly correlated with higher LP success rates.

Conclusions:

• Short, simulator-based tutorials are effective in improving medical students' LP skills.
• This training method enhances procedural competence and patient safety.
• Simulator-based training should be widely implemented in medical education curricula.
