A Visual Analytics Design for Connecting Healthcare Team Communication
  to Patient Outcomes

Communication among healthcare professionals (HCPs) is crucial for the
quality of patient treatment. Surrounding each patient's treatment,
communication among HCPs can be examined as temporal networks, constructed from
Electronic Health Record (EHR) access logs. This paper introduces a visual
analytics system designed to study the effectiveness and efficiency of temporal
communication networks mediated by the EHR system. We present a method that
associates network measures with patient survival outcomes and devises
effectiveness metrics based on these associations. To analyze communication
efficiency, we extract the latencies and frequencies of EHR accesses. Our
visual analytics system is designed to assist in inspecting and understanding
the composed communication effectiveness metrics and to enable the exploration
of communication efficiency by encoding latencies and frequencies in an
information flow diagram. We demonstrate and evaluate our system through
multiple case studies and an expert review.
