TI  - Barriers to retrieving patient information from electronic health record data: 
      failure analysis from the TREC Medical Records Track.
PG  - 180-8
AB  - OBJECTIVE: Secondary use of electronic health record (EHR) data relies on the 
      ability to retrieve accurate and complete information about desired patient 
      populations. The Text Retrieval Conference (TREC) 2011 Medical Records Track was 
      a challenge evaluation allowing comparison of systems and algorithms to retrieve 
      patients eligible for clinical studies from a corpus of de-identified medical 
      records, grouped by patient visit. Participants retrieved cohorts of patients 
      relevant to 35 different clinical topics, and visits were judged for relevance to 
      each topic. This study identified the most common barriers to identifying 
      specific clinic populations in the test collection. METHODS: Using the runs from 
      track participants and judged visits, we analyzed the five non-relevant visits 
      most often retrieved and the five relevant visits most often overlooked. 
      Categories were developed iteratively to group the reasons for incorrect 
      retrieval for each of the 35 topics. RESULTS: Reasons fell into nine categories 
      for non-relevant visits and five categories for relevant visits. Non-relevant 
      visits were most often retrieved because they contained a non-relevant reference 
      to the topic terms. Relevant visits were most often infrequently retrieved 
      because they used a synonym for a topic term. CONCLUSIONS: This failure analysis 
      provides insight into areas for future improvement in EHR-based retrieval with 
      techniques such as more widespread and complete use of standardized terminology 
      in retrieval and data entry systems.
