Key Points Question How much duplicate content is present in electronic medical records, where does it come from, and why is it there? Findings In this cross-sectional analysis of 104 456 653 routinely generated clinical notes, 16 523 851 210 words (50.1% of the total count of 32 991 489 889 words) were duplicated from prior documentation. Duplicate content was prevalent in notes written by physicians at all levels of training, nurses, and therapists and was evenly divided between intra-author and inter-author duplication. Meaning The prevalence of information duplication in electronic medical records suggests that it is an adaptive behavior requiring further investigation so that improved documentation systems can be developed.
