Electronic Medical Record (EMR) have the potential to improve quality of care but to date, there is little research to quantify the effect of EMR as barrier or facilitator of quality. Design and implementation of EMR’s, should not be viewed as an end in distracting them with burdensome documentation or Human-Computer Interaction (HCI) limitations. In an ideal patient-centered process, the provider would focus primarily on the patient. However in the time-constrained framework of office consultations, the EMR competes for the provider’s focus of attention. It is desirable to understand the degree to which EMR task complexity imposes a cognitive burden on providers.
