Case-Based Learning for Bedside Lung Ultrasound Teaching in ICU

Condition(s) studied

Investigational drug(s) / intervention(s)

Case-Based Learning (CBL): Participants study authentic emergency cases, analyze lung ultrasound images, perform bedside scanning under instructor facilitation, and discuss diagnostic reasoning in small groups.

Traditional lecture-based teaching: Participants receive conventional didactic lectures and instructor demonstration of BLUE examination followed by limited practice.

Study summary

This single-center randomized controlled study aims to evaluate the effectiveness of Case-Based Learning (CBL) compared with traditional teaching in clinical training of bedside lung ultrasound (BLUE) for emergency medicine residents and medical students. The hypothesis is that CBL improves theoretical understanding, practical ultrasound skills, and clinical reasoning in emergency settings.

Eligibility

Primary outcome measure(s)

• Objective Structured Clinical Examination (OSCE) Total Score — Within one week after completion of the teaching sessions
  he Objective Structured Clinical Examination (OSCE) total score (0-100 points) evaluates overall bedside lung ultrasound proficiency. It includes five weighted stations: (1) image acquisition and scanning technique (20 points), (2) image interpretation (20 points), (3) clinical decision-making (20 points), (4) structured case reporting and teamwork (20 points), and (5) emergency communication with patients or families (20 points). Each station is rated by three blinded assessors using standardized checklists and global rating scales. Higher scores indicate better ultrasound performance and clinical reasoning ability. Scale Range: 0 (poor performance) to 100 (excellent performance); higher = better
