Item response theory: applications of modern test theory in medical education

CONTEXT: Item response theory (IRT) measurement models are discussed in the context of their potential usefulness in various medical education settings such as assessment of achievement and evaluation of clinical performance. PURPOSE: The purpose of this article is to compare and contrast IRT measurement with the more familiar classical measurement theory (CMT) and to explore the benefits of IRT applications in typical medical education settings. SUMMARY: CMT, the more common measurement model used in medical education, is straightforward and intuitive. Its limitation is that it is sample-dependent, in that all statistics are confounded with the particular sample of examinees who completed the assessment. Examinee scores from IRT are independent of the particular sample of test questions or assessment stimuli. Also, item characteristics, such as item difficulty, are independent of the particular sample of examinees. The IRT characteristic of invariance permits easy equating of examination scores, which places scores on a constant measurement scale and permits the legitimate comparison of student ability change over time. Three common IRT models and their statistical assumptions are discussed. IRT applications in computer-adaptive testing and as a method useful for adjusting rater error in clinical performance assessments are overviewed. CONCLUSIONS: IRT measurement is a powerful tool used to solve a major problem of CMT, that is, the confounding of examinee ability with item characteristics. IRT measurement addresses important issues in medical education, such as eliminating rater error from performance assessments.

建立以医疗为中心的现代医院信息管理系统

医院信息系统（HospitalInformationSystem，简称HIS）是以计算机技术为基础，以医疗信息为内涵的现代医院管理系统。以医疗为中心的HIS，前提是以病人为中心的医院管理核心，基本理论是“以病人、医嘱作为医院信息系统的中心”，从而导向和驱动医院管理中所有其他系统。医院内部信息高速公路，让病人在预检、挂号处开始，信息资料就随信息高速公路而运动至任何一个有关部门，医嘱、处方信息高速公路先于病人直达收费处，再至药房。始终让病人感到服务措施领先一步。以医疗为中心的HIS特征是：一种医疗信息输入，多处可提取，而一处输入又受到多项监控，因此其准确程度相对较高。

Dual computer monitors to increase efficiency of conducting systematic reviews

ObjectiveSystematic reviews (SRs) are the cornerstone of evidence-based medicine. In this study, we evaluated the effectiveness of using two computer screens on the efficiency of conducting SRs.Study Design and SettingA cohort of reviewers before and after using dual monitors were compared with a control group that did not use dual monitors. The outcomes were time spent for abstract screening, full-text screening and data extraction, and inter-rater agreement. We adopted multivariate difference-in-differences linear regression models.ResultsA total of 60 SRs conducted by 54 reviewers were included in this analysis. We found a significant reduction of 23.81 minutes per article in data extraction in the intervention group relative to the control group (95% confidence interval: −46.03, −1.58, P = 0.04), which was a 36.85% reduction in time. There was no significant difference in time spent on abstract screening, full-text screening, or inter-rater agreement between the two groups.ConclusionUsing dual monitors when conducting SRs is associated with significant reduction of time spent on data extraction. No significant difference was observed on time spent on abstract screening or full-text screening. Using dual monitors is one strategy that may improve the efficiency of conducting SRs.
