Table 2: Authorship in electronic health record notes for office visits based on automated text analysis of 84,271 notes from 41 ophthalmology providers.
Character counts are displayed for new and return patient progress notes, based on author and text source (manually-entered vs imported). Only notes with both provider and technician text were analyzed, and only providers with more than thirty notes with provider and technician text were included in the analysis. Comparisons were made between amount of text generated by providers and staff for each encounter type using a paired t-test after data had been log-transformed to convert log-normal distributions to normal distributions.
