Background: At NorthShore University HealthSystem, dermatopathology (DP) case requisitions are received in hand written form or via electronic medical record (EMR). There are multiple categories for requisition data entry including patient demographics, physician name, and procedure site/date. Data entry error propagates inaccurate patient information and potentially delays billing/revenue collection. The DP service maintains a high case volume and thus systematic data entry problems potentially cause considerable documentation error. We reviewed DP data entry errors on hand written requisition forms compared to data entry errors via EMR.
Design: 11,475 DP requisitions (8,545 hand written, 2,930 EMR) were included in the study (4/1/2011-9/30/2011). Data entry errors were documented and categorized as cases were accessioned and reviewed.
Results: Results are illustrated in table 1.

The majority of errors occurred with container labelling. More specifically, procedure site was either not on the container or there was a discrepancy between the site indicated on the container and on the requisition. Container labelling is currently a hand written process. The EMR does not generate labels and 109/113 EMR errors (96%) were related to container labelling.
Conclusions: 1.With both hand written and EMR requisitions, the most common source of error is specimen container labelling.
2.Currently, even with EMR, containers are hand labeled and 96% of EMR errors occurred during this process. Other EMR data entry errors are extremely uncommon (4/2930 cases). This suggests introduction of a labelling process linked to EMR data entry could nearly eliminate data entry errors.
3. Although this study focused on DP cases, the findings can be applied to all types of specimens.
