Health professionals are increasingly expected to identify their own learning needs through a process of ongoing self-assessment. Self-assessment is integral to many appraisal systems and has been espoused as an important aspect of personal professional behaviour by several regulatory bodies and those developing learning outcomes for clinical students. In this review we considered the evidence base on self-assessment since Gordon's comprehensive review in 1991. The overall aim of the present review was to determine whether specific methods of self-assessment lead to change in learning behaviour or clinical practice. Specific objectives sought evidence for effectiveness of self-assessment interventions to: a. improve perception of learning needs; b. promote change in learning activity; c. improve clinical practice; d. improve patient outcomes.
The methods for this review were developed and refined in a series of workshops with input from an expert BEME systematic reviewer, and followed BEME guidance. Databases searched included Medline, CINAHL, BNI, Embase, EBM Collection, Psychlit, HMIC, ERIC, BEI, TIMElit and RDRB. Papers addressing self-assessment in all professions in clinical practice were included, covering under- and post-graduate education, with outcomes classified using an extended version of Kirkpatrick's hierarchy. In addition we included outcome measures of accuracy of self-assessment and factors influencing it. 5,798 papers were retrieved, 194 abstracts were identified as potentially relevant and 103 papers coded independently by pairs using an electronic coding sheet adapted from the standard BEME form. This total included 12 papers identified by hand-searches, grey literature, cited references and updating. The identification of a further 12 papers during the writing-up process resulted in a total of 77 papers for final analysis.
Although a large number of papers resulted from our original search only a small proportion of these were of sufficient academic rigour to be included in our review. The majority of these focused on judging the accuracy of self-assessment against some external standard, which raises questions about assumed reliability and validity of this 'gold standard'. No papers were found which satisfied Kirkpatrick's hierarchy above level 2, or which looked at the association between self-assessment and resulting changes in either clinical practice or patient outcomes. Thus our review was largely unable to answer the specific research questions and provide a solid evidence base for effective self-assessment. Despite this, there was some evidence that the accuracy of self-assessment can be enhanced by feedback, particularly video and verbal, and by providing explicit assessment criteria and benchmarking guidance. There was also some evidence that the least competent are also the least able to self-assess accurately. Our review recommends that these areas merit future systematic research to further our understanding of self-assessment.
As in other BEME reviews, the methodological issues emerging from this review indicate a need for more rigorous study designs. In addition, it highlights the need to consider the potential for combining qualitative and quantitative data to further our understanding of how self-assessment can improve learning and professional clinical practice.
人们越来越期望卫生专业人员通过持续的自我评估过程来确定自己的学习需求。自我评估是许多评估系统不可或缺的一部分,并且被多个监管机构以及为临床学生制定学习成果的机构视为个人职业行为的一个重要方面。在本次综述中,我们考察了自1991年戈登进行全面综述以来有关自我评估的证据基础。本综述的总体目标是确定自我评估的特定方法是否会导致学习行为或临床实践的改变。具体目标是寻找证据证明自我评估干预措施的有效性,以:a. 提高对学习需求的认知;b. 促进学习活动的改变;c. 改善临床实践;d. 改善患者结局。
本综述的方法是在一系列研讨会上开发和完善的,有一位BEME系统评价专家提供意见,并遵循BEME指南。检索的数据库包括Medline、CINAHL、BNI、Embase、EBM Collection、Psychlit、HMIC、ERIC、BEI、TIMElit和RDRB。纳入了涉及临床实践中所有专业自我评估的论文,涵盖本科和研究生教育,使用柯克帕特里克层次结构的扩展版本对结果进行分类。此外,我们纳入了自我评估准确性的结果指标及其影响因素。共检索到5798篇论文,确定194篇摘要可能相关,103篇论文由两人使用根据标准BEME表格改编的电子编码表独立编码。这一总数包括通过手工检索、灰色文献、引用文献和更新确定的12篇论文。在撰写过程中又确定了12篇论文,最终共有77篇论文进行分析。
尽管我们最初的搜索产生了大量论文,但其中只有一小部分具有足够的学术严谨性可纳入我们的综述。这些论文大多集中在根据某些外部标准判断自我评估的准确性,这引发了对这个“黄金标准”假定的可靠性和有效性的质疑。未找到符合柯克帕特里克层次结构2级以上的论文,也没有研究自我评估与临床实践或患者结局的相应变化之间的关联。因此,我们的综述在很大程度上无法回答具体的研究问题,也无法为有效的自我评估提供坚实的证据基础。尽管如此,有一些证据表明,反馈(特别是视频和口头反馈)以及提供明确的评估标准和基准指导可以提高自我评估的准确性。也有一些证据表明,能力最差的人自我评估准确的能力也最差。我们的综述建议这些领域值得未来进行系统研究,以加深我们对自我评估的理解。
与其他BEME综述一样,本次综述中出现的方法学问题表明需要更严谨的研究设计。此外,它突出了需要考虑结合定性和定量数据的可能性,以加深我们对自我评估如何改善学习和专业临床实践的理解。
