摘要:

随着电子健康档案的广泛应用,临床医生在大量的患者健康档案中检索重要信息时,往往面临时间压力。虽然搜索功能可以是浏览患者记录的有用替代方案,但对于临床医生来说,重复搜索类似患者的相同或类似信息是很麻烦的。在这种情况下,迫切需要建立有效的推荐系统,可以为临床医生生成准确的搜索词推荐。在这篇手稿中,我们开发了一个混合协同过滤模型,使用患者的遭遇和搜索词信息,为临床医生推荐下一个搜索词,以快速检索重要信息。对于每例患者,模型将推荐与他/她最近的ICD代码具有高共现频率或与该患者最近的检索词高度相关的术语。我们已经进行了全面的实验来评估所提出的模型,实验结果表明,我们的模型可以优于所有最先进的基线方法的前N个搜索词推荐不同的数据集。

英文摘要:

With increasing and extensive use of electronic health records, clinicians are often under time pressure when they need to retrieve important information efficiently among large amounts of patients' health records in clinics. While a search function can be a useful alternative to browsing through a patient's record, it is cumbersome for clinicians to search repeatedly for the same or similar information on similar patients. Under such circumstances, there is a critical need to build effective recommender systems that can generate accurate search term recommendations for clinicians. In this manuscript, we developed a hybrid collaborative filtering model using patients' encounter and search term information to recommend the next search terms for clinicians to retrieve important information fast in clinics. For each patient, the model will recommend terms that either have high co-occurrence frequencies with his/her most recent ICD codes or are highly relevant to the most recent search terms on this patient. We have conducted comprehensive experiments to evaluate the proposed model, and the experimental results demonstrate that our model can outperform all the state-of-the-art baseline methods for top-N search term recommendation on different datasets.
