Competence is essential for health care professionals. Current methods to assess competency, however, do not efficiently capture medical students' experience. In this preliminary study, we used machine learning and natural language processing (NLP) to identify geriatric competency exposures from students' clinical notes. The system applied NLP to generate the concepts and related features from notes. We extracted a refined list of concepts associated with corresponding competencies. This system was evaluated through 10-fold cross validation for six geriatric competency domains: "medication management (MedMgmt)", "cognitive and behavioral disorders (CBD)", "falls, balance, gait disorders (Falls)", "self-care capacity (SCC)", "palliative care (PC)", "hospital care for elders (HCE)" - each an American Association of Medical Colleges competency for medical students. The systems could accurately assess MedMgmt, SCC, HCE, and Falls competencies with F-measures of 0.94, 0.86, 0.85, and 0.84, respectively, but did not attain good performance for PC and CBD (0.69 and 0.62 in F-measure, respectively).
能力对于医疗保健专业人员至关重要。然而,目前评估能力的方法并不能有效地反映医学生的经历。在这项初步研究中,我们使用机器学习和自然语言处理(NLP)从学生的临床记录中识别老年医学能力暴露情况。该系统应用NLP从记录中生成概念和相关特征。我们提取了与相应能力相关的精炼概念列表。该系统通过10折交叉验证对六个老年医学能力领域进行了评估:“药物管理(MedMgmt)”、“认知和行为障碍(CBD)”、“跌倒、平衡、步态障碍(Falls)”、“自我护理能力(SCC)”、“姑息治疗(PC)”、“老年人医院护理(HCE)”——每个都是美国医学院协会对医学生的能力要求。该系统可以分别以0.94、0.86、0.85和0.84的F值准确评估MedMgmt、SCC、HCE和Falls能力,但对于PC和CBD(F值分别为0.69和0.62)的表现不佳。
