ObjectiveTo investigate the application effects of problem-based learning(PBL) mode assisted by picture archiving and communication system(PACS) in the teaching of rare cardiovascular diseases by cardiovascular specialists.
MethodsA total of 16 students who underwent standardized training for cardiovascular specialists were selected as the study objects, and divided into the observation group and control group(8 trainees in each group).The observation group was taught using PBL based on the PACS system, while the control group was taught only using PBL teaching.The rare disease theory in all trainees was tested before and after the course to assess their knowledge of rare diseases.After the course, the course performance(including regular grades and theory tests) in all students were assessed, and the course satisfaction was investigated by questionnaire.
ResultsThere was no statistical significance in the results of the theoretical test on rare diseases before the lecture between two groups(P>0.05).However, the total scores in the observation group were significantly higher than those in control group after the lecture(P < 0.01).The scores of individual speaking enthusiasm and group cooperation in the observation group were significantly higher than those in control group(P < 0.01).In theory examination, the scores of objective questions, image analysis and case analysis in the observation group were significantly higher than those in control group(P < 0.01).The results of questionnaire survey showed that the satisfaction in the improvement of cardiovascular image reading ability in the observation group was better than that in control group(P < 0.05).
ConclusionsThe PACS-assisted PBL teaching mode is helpful to improve the cognition of special training students to rare cardiovascular diseases, and improve the teaching quality.
