[摘要] 目的 探索教师标准化患者(TSP)+病例导引教学(CBL)模式解决短暂性脑缺血发作(TIA)课临床教学老大难问题的可行性。 方法 分别对八年制临床医学系2012级(38人)和2011级(38人)的TIA课采用TSP+CBL教学法和单纯TSP教学法。学习结束时,比较分析两组教学课堂考核成绩和教学效果调查问卷自评分。用t检验评价2种方法的教学效果。 结果 TSP+CBL组学生课堂考核平均分达(88.763.48)分,显著高于TSP 组的(85.273.01)分(P 0.05)。TSP+CBL组尤在临床思维、与人合作和解决问题能力方面成绩明显高于TSP组(P 0.01)。TSP+CBL组对教学效果调查问卷的平均自评分为(92.291.56)分,显著高于TSP组的(85.273.01)分(P 0.01)。TSP+CBL组在对教材内容理解掌握程度、对新教学法满意程度、有利理论与临床实践结合3个方面显著高于TSP组(均P 0.01)。 结论 以TSP+CBL的教学模式值得推广,对此类发作-间歇型疾病的临床教学具有普遍性意义。

[Abstract] Objective To evaluate the feasibility of teacher as standardized patient (TSP) combined with case based learning (CBL) teaching mode to solve clinical teaching persistent problem of the transient ischemic attack (TIA). Methods TSP combined with CBL was used in 38 eight-year medical students of grade 2012, while TSP was used in 38 eight-year medical students of grade 2011. At the end of the study, teaching effect was assessed by the final examination and questionnaires. The data were processed by t test. Results The average test score in the TSP combined with CBL group was (88.763.48) scores, which was significantly higher than that in the TSP group (85.273.01) scores (P 0.05). Scores of clinical thinking, cooperating with others and solving problems in TSP combined with CBL group were significantly higher than those in TSP group (P 0.01). The score of the questionnaire in the TSP combined with CBL group was (92.291.56) scores, which was significantly higher than (85.273.01) scores in TSP group (P 0.01). Scores of understanding of teaching materials, satisfaction with new teaching method, combination of favorable theory and clinical practice in the TSP combined with CBL group were better than those of TSP group. Conclusion The TSP combined with CBL can be a valuable strategy, which has universal significance in clinical teaching to such attacks-intermittent disease.

短暂性脑缺血发作(transient ischemic attack,TIA)是神经内科教学中的重要课程。TIA为发作性疾病,患者多于间歇期就诊,无临床体征,诊断主要靠问诊[1],故成为教学中的难点。单纯依赖老师填鸭式灌输、学生死记硬背的传统授课模式[2],已无法满足现代医学生的教学需求。 当今医学领域教学模式主要有教师标准化患者(teacher as standardized patient,TSP)教学法[3-4]、问题导引教学法[5]、病例导引教学(case based learning,CBL)法[6]、团队为基础教学法[7]等,实践证实各有千秋。为适应新医学教育模式转变,符合培养全面素质人才的高等教育理念,本教研组在教学中结合国情进行探索。从2014年4月起选择TSP+CBL模式TIA课教学法,经过2年多的与单纯TSP模式对照评估,发现此模式对TIA课教学效果有显著性提高,现报道如下:
1 对象与方法
1.1 研究对象
选取北京大学第三医院八年制临床医学系2011、2012级各38人为研究对象。前者采用单纯TSP教学法(TSP组),后者用TSP与CBL结合模式(TSP+CBL组)。两组TSP、带教老师相同,两组教学研究前平均学习成绩、年龄及性别构成比较差异无统计学意义(P 0.05),具有可比性。
1.2 方法
1.2.1 TSP 选择与培训 选择沟通和表演能力好的医护志愿者2名,培训4个半天。通过梳理内容,重点学习患者被问诊时的心理反应、常见表述方式和模拟技巧,包括服饰、情景设计及神态、动作模仿,按病案和教学大纲要求,经全面考核均为合格者。
TIA课病案题目定为头晕,内容:模拟场景设计、患者一般情况、主诉和现病史、其他(包括文化、经济、职业背景)、辅助检查、模拟要点和道具化妆。由临床和教学经验丰富的高年资主任医师根据数位病例原型撰写初稿,经全科充分讨论,由科主任定稿。
1.2.2 TSP+CBL组的教学内容 第1步:教学前 3 d,发放课时安排、教学大纲要求和特意设计不完整病案以及提供CBL计划,包括TIA发作特征、启发性问题、可利用资源(如图书馆、资料室、网络、专业参考书)等。学生自主检索资料学习,寻找答案。
第2步:授课开始35 min内,学生充当医生。将全班38人分成两组,每组推荐2名同学,通过问诊、查体,独立向TSP获取病史资料。其他学生一起思考、记录,随时给提问同学以提示和补充。注意问诊沟通技巧,如:启动问诊、核实所获信息、注意安抚患者情绪等。期间, 部分影像、化验等辅助检查结果, 通过幻灯提供(只有检查结果,没有诊断),TSP始终不参与学生讨论。而后,所有同学均完成1份病史
