Case reports are of minor importance in evidence-based medicine but can nonetheless make meaningful contributions to both knowledge and education. Although many traditional medical journals publish fewer case reports in this era of space constraints and preoccupation with Impact Factors, new Internet-based journals are appearing that focus exclusively on reports of individual cases. Given the variability of documentation, objectivity, and interpretation among the case reports now accessible by clinicians and trainees, it is important to be able to read them critically and to use the information they contain appropriately. This article discusses factors to consider in evaluating individual case reports, and provides a practical semi-quantitative scheme for assessing their potential validity and educational value.
病例报告在循证医学中重要性较低，但仍可为知识和教育做出有意义的贡献。尽管在这个受篇幅限制且专注于影响因子的时代，许多传统医学期刊发表的病例报告较少，但专门关注个别病例报告的新型网络期刊正在涌现。鉴于临床医生和实习生目前可获取的病例报告在记录、客观性和解读方面存在差异，能够批判性地阅读这些报告并恰当地利用其中包含的信息非常重要。本文讨论了评估个别病例报告时应考虑的因素，并提供了一个实用的半定量方案，以评估其潜在的有效性和教育价值。
