Abstract

General Practitioners often encounter unanswered medical questions about patient symptoms or treatments at the point of care. Despite advances in information technology and the availability of the Internet, it is estimated that half of these questions remain unanswered. This proportion has remained stable over time. International Clinical Practice Guidelines (CPGs), which contain recently updated evidence, are an optimal source of information; more than 90% of relevant clinical questions can be answered using these guidelines. However, the large volume of these CPGs limits their accessibility at the point of care. We developed an Information Retrieval System using serialized Gensim TFIDF and LSI models to extract relevant answers to clinical questions. The true answer to clinical questions can be found in the first six answers of the algorithm in 98% of cases. This algorithm can be helpful for general practitioners to take greater advantage of CPGs at the point of care.

使用Gensim TFIDF和LSI模型从临床实践指南中检索临床问题的潜在答案。
全科医生经常在护理点遇到关于患者症状或治疗的未解之谜。尽管在信息技术和互联网的可用性方面取得了进步,但据估计,这些问题中有一半仍未得到解答。这一比例一直保持稳定。国际临床实践指南(CPGs)包含最近更新的证据,是最佳的信息来源;超过90%的相关临床问题可以通过这些指南得到解答。然而,这些cpg的大容量限制了它们在护理点的可及性。我们开发了一个信息检索系统,使用序列化Gensim TFIDF和LSI模型来提取临床问题的相关答案。临床问题的真实答案在98%的病例中可以在算法的前六个答案中找到。该算法可以帮助全科医生在护理点上更充分地利用CPGs。
