The Edmonton Labeled Visual Information System (ELVIS) is a novel method of documenting clinical information because it is a pictorial method of representing cancer burden and treatment. This randomized, crossover, multiperiod trial involved 16 physicians who each reviewed two ELVIS and two control (text) cancer patient cases (total 32 ELVIS and 32 text cases). Short-answer questionnaires were administered immediately and 18--24 hours following. Mean (+/- SD) recall of basic disease and treatment information was superior immediately following the ELVIS cases (83% +/- 14%) versus text cases (60% +/- 14%, P < 0.0001) and 18--24 hours later (ELVIS cases 65% +/- 21% versus text cases 43% +/- 21%, P < 0.0001). Mean (+/- SD) time required to memorize information was reduced in the ELVIS cases (4 +/- 2 min) versus text cases (13 +/- 6 min, P < 0.0001). Ratings of overall physician preference strongly favored the ELVIS over text. The data indicate that ELVIS aids the process of learning complex cancer patient histories.
埃德蒙顿标记视觉信息系统（ELVIS）是一种记录临床信息的新方法，因为它是一种用图片形式呈现癌症负担和治疗情况的方法。这项随机、交叉、多阶段试验涉及16名医生，每位医生审阅两个ELVIS病例和两个对照（文本）癌症患者病例（共32个ELVIS病例和32个文本病例）。在审阅后立即以及18 - 24小时后进行简短回答问卷调查。ELVIS病例后立即对基本疾病和治疗信息的平均（±标准差）回忆率高于文本病例（ELVIS病例为83%±14%，文本病例为60%±14%，P < 0.0001），18 - 24小时后也是如此（ELVIS病例为65%±21%，文本病例为43%±21%，P < 0.0001）。ELVIS病例中记忆信息所需的平均（±标准差）时间比文本病例减少（ELVIS病例为4±2分钟，文本病例为13±6分钟，P < 0.0001）。医生总体偏好评分强烈倾向于ELVIS而非文本。数据表明，ELVIS有助于学习复杂癌症患者病史的过程。
