Abstract

Linking electronic health records (EHRs) to relevant education materials can provide patient-centered tailored education which can potentially improve patients’ medical knowledge, self-management and clinical outcome. It is shown that EHR query generation using key concept identification improves retrieval of education materials. In this study, we explored domain adaptation approaches to improve key concept identification. Our experiments show that a 20.7% improvement in the F1 measure can be achieved by leveraging data from Wikipedia. Queries generated from the best performing approach achieved a 20.6% and 27.8% improvement over the queries generated from the baseline approach.

Highlights

  • Providing patients with access to their own electronic health records (EHRs) has been shown to benefit patients in many ways, including enhanced medical understanding, and better medication adherence (Delbanco et al, 2012)

  • It is shown that identifying the key concepts is an effective strategy to generate queries to link EHR notes to education materials

  • We explored several domain adaptation approaches to improve key concept identification from EHR notes

Summary

Introduction

Providing patients with access to their own electronic health records (EHRs) has been shown to benefit patients in many ways, including enhanced medical understanding, and better medication adherence (Delbanco et al, 2012). EHR notes present unique challenges to the average patients. A national survey in US shows that 36% of the population have basic or below basic health literacy (National Center for Education Statistics, 2003). The language in the EHR notes is difficult for non-medical professionals to comprehend because of the prevalence of medical terms, abbreviations, and domain-specific language patterns. Coupled with limited average health literacy, the valuable and authoritative information contained in the EHR is less accessible to the patients, who stand to benefit the most from the information
