As electronic medical records (EMRs) capture increasing amounts of data per patient, compiling a clinical narrative becomes cognitively more demanding. This information overload is particularly challenging in settings such as the intensive care unit (ICU) where a new data point may be added to a patient’s record almost every minute. Moreover, the display of patient data in current EMRs is not specific to the clinical context and burdens the physician.

An EMR that focuses the physician’s attention on relevant patient data could help reduce the time needed to assess the patient’s condition and improve the quality of the resulting judgments, enabling improved decision making, reduced medical errors, and greater efficiency. We built a prototype LEMR system that records how physicians view EMR data, which we used to train models that predict which EMR data will be relevant in a given patient. We call this approach a Learning EMR (LEMR).
