To evaluate the instructional efficacy of the national continuing medical education program, the "Cerebrovascular Ultrasound Training Course".

A cross-sectional questionnaire survey was conducted among trainees who attended the course from 2021 to 2025. The questionnaire covered demographic information, perceived teaching effectiveness, self-assessed competency before and after training, clinical application of acquired knowledge, and suggestions for improvement. A five-point Likert scale was used for scoring. Paired-samples t test was used to compare changes in self-assessed core competencies before and after training. Independent-samples t test and one-way analysis of variance (ANOVA) were used to analyze differences in training effectiveness among trainees according to hospital level, professional title, and occupational category, respectively.

Of the 127 questionnaires distributed 126 were valid, with an effective response rate of 99.2%. Among the 126 trainees, 99 were female (78.6%), 102 were aged 35–54 years (81.0%), 65 were clinicians (51.6%), and 98 had attended the course within the past three years (77.8%). Teaching effectiveness was evaluated across five domains: (1) improvement in the ultrasound diagnosis and clinical analysis of cerebrovascular diseases (4.54±0.57); (2) enhancement of standardized operation and result interpretation for transcranial Doppler (4.57±0.53); (3) increased confidence in technology promotion dissemination (4.49±0.59); (4) expanded understanding of clinical application scenarios (4.52±0.56); (5) broadened academic perspectives, with scores 4.49±0.58. Post-training self-assessed scores for all core competencies were significantly higher than pre-training scores (all P＜0.05). Furthermore, 95.2% of the trainees had applied the training content to clinical practice to varying degrees; 57.1% reported that existing programs in their institutions had become more standardized, and 19.8% had newly initiated related programs. No significant differences in training effectiveness were observed among trainees from different hospital levels, professional titles, or occupational categories (all P＞0.05).

The "Cerebrovascular Ultrasound Training Course" has demonstrated significant positive impact on improving trainees' cerebrovascular ultrasound-related competencies, promoting clinical application and technology dissemination, and broadening academic perspectives. This program represents a high-value continuing medical education initiative with broad applicability across diverse clinical settings.
