The Application of Case-Based Learning (CBL) Combined with PDCA Cycle in the Clinical Teaching Practice of Breast Ultrasound in Standardized Residency Training

Background: The integration of case-based learning (CBL) with the plan-do-check-act (PDCA) cycle has potential benefits for clinical education, yet its efficacy in ultrasound residency training, particularly for breast ultrasound, requires evaluation. Aim: This study aimed to assess the impact of a combined CBL and PDCA cycle teaching model on the clinical thinking and skills of ultrasound residents compared to traditional teaching methods. Methods: A comparative study was conducted at Sichuan Provincial People’s Hospital’s ultrasound medicine base, from August 2020 to June 2023, focusing on residents in training. Sixty-one trainees were randomly divided into two groups: a joint group (n = 31) taught using a PDCA cycle-based model integrated with CBL and a traditional group (n = 30) taught with conventional methods. Both groups underwent a 20-hour course and were subsequently evaluated on theoretical knowledge, clinical thinking, and skills. Comparative statistical analysis was performed to evaluate the performance differences between the two groups. Results: The joint group demonstrated significantly better clinical thinking and skills operation than the traditional group ( P < 0.05). No significant difference was observed between the groups regarding theoretical knowledge ( P > 0.05). Conclusions: The combined CBL-PDCA cycle teaching mode significantly enhances the clinical thinking abilities and operational skills of residents in breast ultrasound training. This innovative approach shows promise as an effective educational strategy to foster intrinsic motivation and higher order learning capabilities among ultrasound residents.
