Application of problem based learning (PBL) and case based learning (CBL) in the teaching of international classification of diseases encoding

Abstract

AbstractTo study the application of PBL combined with CBL teaching mode in the teaching of international classification of diseases (ICD) encoding, so as to improve students' grasp of ICD encoding knowledge. From March 2020 to June 2020, 50 students majoring in health information management who were interns in a Grade A general hospital were selected as the research participants and randomly divided into experimental group and control group, 25 in each group. The experimental group and the control group adopted the PBL combined CBL teaching mode and the traditional teaching mode respectively to carry out the classification and coding teaching. The academic achievement of the two groups of students was evaluated by means of achievement assessment and questionnaire survey based on information processing theory. The scores of theoretical knowledge in the experimental group and the control group were 79.78 ± 8.55 and 70.92 ± 10.81, respectively, and the scores of skill operation in the two groups were 79.76 ± 8.28 and 70.00 ± 10.41, respectively. The test scores of the experimental group were higher than those of the control group, and the difference was statistically significant (P < 0.05). The scores of knowledge acquisition ability of experimental group and control group were 16.72 ± 1.79 and 16.60 ± 2.36, the scores of knowledge sharing ability were 24.20 ± 2.61 and 21.00 ± 2.65, the scores of knowledge storage ability were 20.80 ± 2.47 and 17.24 ± 4.90, respectively. The scores of knowledge application ability were 14.00 ± 1.80 and 11.00 ± 2.69, the scores of knowledge innovation ability were 20.16 ± 2.34 and 18.08 ± 3.70, and the total scores were 95.88 ± 6.08 and 83.92 ± 11.30, respectively. The scores of all questionnaires in the experimental group were higher than those in the control group. The scores of knowledge sharing ability, knowledge storage ability, knowledge application ability, knowledge innovation ability and total score between the two groups were higher than those of the control group, and the differences were statistically significant (P < 0.05). PBL combined with CBL teaching model has good academic achievement in ICD encoding teaching, which can significantly improve academic performance and learning ability, and is worthy of promotion.
