Abstract

Objective To explore the effects of virtual cases in clinical diagnosis and treatment combined with PBL in diagnostic experiments teaching. Methods From March to July in 2018, totally 97 students from grade 2016, five years undergraduate clinical medicine in Jining Medical University were randomly selected and divided into the experimental group (48 students) and control group (49 students). The experimental group adopted virtual cases in clinical diagnosis and treatment combined with PBL teaching method , while the control group received traditional teaching methods.At the end of experimental class, the learning outcomes of students in the two groups was valued by questionnaire survey and examinations. Results The results of basic knowledge of diagnostics, case analysis and theoretical assessment in the experimental group were (66.7 ± 6.45), (14.3 ± 1.75) and (80.9 ± 7.36) respectively, which were better than those in the control group (62.3 ± 8.42), (13.2 ± 2.28) and (75.5 ± 9.31). The differences were statistically significant The results of questionnaire showed that compared with the control group, the students in the experimental group increased their interest in learning [39(81.2) vs 26(53.1)], their ability to collect medical history [44 (91.7) vs 32(65.3)], their communication and expression ability [40(83.3) vs 29(59.2)], their diagnostic analysis ability [38 (79.2) vs 24 (49.0)], their diagnostic thinking ability [41(85.4) vs 28(57.1)] and their satisfaction with the teaching mode [44(91.7) vs 28(57.1)], the difference was statistically significant (all P<0.05). Conclusions The application of virtual cases in clinical diagnosis and treatment combined with PBL was effective and feasible in diagnostic experiments teaching. It can improve the learning outcomes, so is better than the traditional teaching mode. Key words: Virtual clinical case; Diagnostic experiment; Teaching method; Problem-based learning

虚拟病例在临床诊疗中的应用，结合PBL在诊断实验教学中的应用

目的探讨虚拟病例在临床诊疗中的应用，结合PBL在诊断实验教学中的应用效果。方法2018年3月至7月，随机抽取济宁医科大学临床医学5年制本科2016级学生97名，分为实验组(48名)和对照组(49名)。实验组采用虚拟病例临床诊疗结合PBL教学方法，对照组采用传统教学方法。在实验课结束时，通过问卷调查和考试对两组学生的学习成果进行评价。结果实验组在诊断基础知识、病例分析和理论评价方面分别为(66.7±6.45)、(14.3±1.75)和(80.9±7.36)，优于对照组(62.3±8.42)、(13.2±2.28)和(75.5±9.31)。问卷调查结果显示，与对照组相比，实验组学生的学习兴趣[39(81.2)比26(53.1)]、病史收集能力[44(91.7)比32(65.3)]、沟通表达能力[40(83.3)比29(59.2)]、诊断分析能力[38(79.2)比24(49.0)]有所提高。诊断思维能力[41(85.4)比28(57.1)]、教学模式满意度[44(91.7)比28(57.1)]，差异均有统计学意义(P<0.05)。结论将虚拟病例应用于临床诊疗结合PBL在诊断实验教学中是有效可行的。它可以提高学习效果，因此优于传统的教学模式。关键词:虚拟临床病例;诊断试验;教学方法;问题式学习
