ABSTRACT
INTRODUCTION When considered from the patient’s perspective, the ambulatory electronic health record (AEHR) is probably the closest approximation of the patient’s archetype of MyChart, a cradle-to-grave record of a patient’s healthy growth, sickness, recovery, and aging. Over the past several decades various specialty systems, acute care systems, ancillary systems, and ambulatory systems have advanced individually and have converged as well. Increasingly a representation of this vernacular chart is emerging either through large multi-functioned EHRs or the aggregation of data from disparate systems through sophisticated interfaces and information exchange. is reects technological advancement, organizational changes within healthcare, and evolving reimbursement methods. It also creates new problems of how to sort and organize so much information to prevent data overload, alert fatigue, and a very dierent kind of provider ineciency than was the challenge of AEHR pioneers decades ago.
