The knowledge gaps and recommendations for advancing EHR interrogation

Aspects	Knowledge Gaps	Recommendations
User	Lack of measure of information need complexity Lack of knowledge of how the cognitive styles of medical researchers affect the information seeking process	Develop metrics for measuring EHR information need complexities Conduct qualitative studies of the information seeking processes of multidisciplinary medical researchers and their barriers to clinical data access
Query Formulation Channel	Lack of formalized structure for the medical researcher to express their information need Poor understanding of the data need- negotiation process performed by data intermediaries	Investigate other formal structures used for document retrieval, i.e. PICO framework Support reference interview for EHR data interrogation
