BackgroundElectronic medical records (EMRs) provide multiple efficiencies in communication to clinicians. The ability to copy and paste text in an EMR can be useful; however, it also conveys a risk of inaccurate documentation. Studies in international settings have described such overuse of copying to result in 'note bloat', with the dilution of relevant clinical information and potential clinical detriment.AimTo determine the frequency of erroneous copying, characterise the component of notes in which this occurs and determine the performance of similarity metrics in the prediction of notes likely to have erroneous copying.MethodsA cross-sectional evaluation of all ward round notes over a 48-h period for all long-stay (>48 h) medical services, except the Acute Medical Unit, at the Lyell McEwin Hospital, a 257-bed tertiary hospital in South Australia. Four similarity metrics were evaluated: longest-sequential series of unchanged characters, similarity score (Difflib SequenceMatcher), Levenshtein distance and the Jaccard index.ResultsOne hundred twenty-eight patients were included. The number of patients who had a ward round note on two consecutive days was 97 out of 128 (75.8%). Erroneous copying was found in 8.3% of ward round notes. All (eight out of eight, 100%) of these instances of erroneous copying were in the 'issues list'. A threshold of >850 unchanged sequential characters, when compared with the ward round note the preceding day, demonstrated reasonable performance in the prediction of erroneous copying.ConclusionsErroneous copying may occur in up to 8.3% of ward round notes in a variety of medical services. Automated strategies to help address this issue should be explored.© 2024 Royal Australasian College of Physicians.
