To develop a valid and reliable instrument for the assessment of pediatric basic life support (PBLS).
An assessment instrument for PBLS was developed, based on 3 existing scoring systems and the European Resuscitation Council PBLS guideline. We tested if experienced PBLS instructors performed better than medical students on a standard PBLS examination on a low-fidelity pediatric manikin (construct validity). To pass the examination, 15 penalty points or less were required. The examinations were videotaped. One researcher assessed all videos once, and approximately half of them twice (intrarater reliability). A second researcher independently assessed part of the videos (interrater reliability). The time needed to assess 1 examination was determined.
Face and content validity were established, because PBLS experts reached consensus on the instrument and because the instrument incorporated all items of the European Resuscitation Council algorithm. Of the 157 medical students that were scored, 98 (62.4%) passed the examination. Fourteen PBLS instructors were scored; all passed (100%). Pass rate (62.4% vs 100%) and median penalty points (15 [interquartile range, 10-22.5] vs 7.5 [interquartile range, 1.25-10]) were significantly different between students and instructors (P = 0.005 and <0.001, respectively). Reassessment demonstrated a κ for intrarater reliability of 0.62 (95% confidence interval, 0.45-0.81) (substantial agreement); κ for interrater reliability was 0.51 (95% confidence interval, 0.09-0.93) (moderate agreement). It took approximately 3 minutes to assess 1 videotaped examination.
Our instrument for the (video-based) assessment of PBLS is valid and sufficiently reliable. It is also designed to be practical, time-efficient, and applicable in various settings, including resource limited.
开发一种用于评估儿科基础生命支持（PBLS）的有效且可靠的工具。
根据现有的 3 种评分系统和欧洲复苏委员会 PBLS 指南，开发了一种用于 PBLS 的评估工具。我们测试了经验丰富的 PBLS 讲师在低保真儿科人体模型上的标准 PBLS 考试中是否比医学生表现更好（结构有效性）。为了通过考试，需要获得 15 分或更少的扣分。考试进行了录像。一名研究人员一次性评估了所有视频，大约一半的视频评估了两次（组内信度）。另一名研究人员独立评估了部分视频（组间信度）。确定了评估 1 次考试所需的时间。
确立了表面有效性和内容有效性，因为 PBLS 专家就该工具达成了共识，并且该工具纳入了欧洲复苏委员会算法的所有项目。在被评分的 157 名医学生中，有 98 人（62.4%）通过了考试。14 名 PBLS 讲师被评分，均通过（100%）。学生和讲师之间的通过率（62.4%比 100%）和中位数扣分（15 [四分位距，10-22.5]比 7.5 [四分位距，1.25-10]）差异有统计学意义（P=0.005 和 <0.001）。重新评估显示组内信度的 κ 值为 0.62（95%置信区间，0.45-0.81）（高度一致）；组间信度的 κ 值为 0.51（95%置信区间，0.09-0.93）（中度一致）。评估 1 个录像考试大约需要 3 分钟。
我们用于（基于视频的）PBLS 评估的工具具有有效性和足够的可靠性。它还旨在具有实用性、高效性和适用性，可用于各种环境，包括资源有限的环境。
