Experience from other domains suggests that videotaping and analyzing actual clinical care can provide valuable insights for enhancing patient safety through improvements in the process of care. Methods are described for the videotaping and analysis of clinical care using a high quality portable multi-angle digital video system that enables simultaneous capture of vital signs and time code synchronization of all data streams. An observer can conduct clinician performance assessment (such as workload measurements or behavioral task analysis) either in real time (during videotaping) or while viewing previously recorded videotapes. Supplemental data are synchronized with the video record and stored electronically in a hierarchical database. The video records are transferred to DVD, resulting in a small, cheap, and accessible archive. A number of technical and logistical issues are discussed, including consent of patients and clinicians, maintaining subject privacy and confidentiality, and data security. Using anesthesiology as a test environment, over 270 clinical cases (872 hours) have been successfully videotaped and processed using the system.
其他领域的经验表明，录制并分析实际临床护理过程可为通过改善护理流程提高患者安全提供宝贵见解。本文介绍了使用高质量便携式多角度数字视频系统录制和分析临床护理的方法，该系统能够同步采集生命体征并实现所有数据流的时间码同步。观察者可以在实时（录制过程中）或观看先前录制的录像带时进行临床医生绩效评估（如工作量测量或行为任务分析）。补充数据与视频记录同步，并以电子方式存储在分层数据库中。视频记录被转移到DVD上，形成一个小巧、廉价且易于访问的存档。文中讨论了一些技术和后勤问题，包括患者和临床医生的同意、维护受试者隐私和保密性以及数据安全。以麻醉学作为测试环境，使用该系统已成功录制并处理了270多个临床病例（872小时）。
