The Department of Veterans Affairs Medical Centers implemented the Bar Code Medication Administration (BCMA) into their practices between 1999 and 2000. The BCMA has significantly influenced physicians' daily workflows, with electronic systems helping to reduce medication errors. However, cognitive overload and related issues are common, highlighting the need for more intensive research on the Electronic Medication Administration Record (eMARs) to find solutions that alleviate these challenges for physicians. This research aims to identify the current usability problems in the Veteran's Affairs (VA's) hospital's eMAR/BCMA system and investigate how these systems contribute to physician overload, leading to medical errors and suboptimal patient outcomes.
