Computerized patient records have long offered the promise of facilitated access to patient data for clinical decision-making. Nonetheless, the decision process benefits of improved patient data access have been poorly quantified by prior informatics research. We conducted a pilot study to test the feasibility of study methods and gather data for the planning of a future clinical trial designed to assess the impact of patient data summary displays on serum lipid test interpretation time, on targeted data retrieval time for related data, and on decision quality. The pilot demonstrated feasibility and high face validity of the decision-making simulation methods used. Problem-focused patient data summaries appear to reduce time-based decision performance measures by 40-50%, and may improve decision quality even without the inclusion of knowledge-based recommendations or guideline representations.
长期以来，计算机化的患者记录有望为临床决策提供便利，使人们能够更方便地获取患者数据。尽管如此，先前的信息学研究对改善患者数据获取所带来的决策过程益处的量化程度很低。我们进行了一项试点研究，以测试研究方法的可行性，并收集数据，为未来的一项临床试验做规划，该试验旨在评估患者数据摘要显示对血脂测试解读时间、相关数据的目标数据检索时间以及决策质量的影响。该试点证明了所使用的决策模拟方法的可行性和较高的表面效度。以问题为重点的患者数据摘要似乎能将基于时间的决策绩效指标降低40%-50%，并且即使不纳入基于知识的建议或指南表述，也可能提高决策质量。
