Description:
Background and Objective Accurately recording vaccine lot number, expiration date, and product identifiers, in patient records is an important step in improving supply chain management and patient safety in the event of a recall. These data are being encoded on two-dimensional (2D) barcodes on most vaccine vials and syringes. Using electronic vaccine administration records, we evaluated the accuracy of lot number and expiration date entered using 2D barcode scanning compared to traditional manual or drop-down list entry methods. Methods We analyzed 128,573 electronic records of vaccines administered at 32 facilities. We compared the accuracy of records entered using 2D barcode scanning with those entered using traditional methods using chi-square tests and multilevel logistic regression. Results When 2D barcodes were scanned, lot number data accuracy was 1.8 percentage points higher (94.3% to 96.1%, P < .001) and expiration date data accuracy was 11 percentage points higher (84.8% to 95.8%, P < .001) compared with traditional methods. In multivariate analysis, lot number was more likely to be accurate (aOR = 1.75; 99% CI, 1.57–1.96) as was expiration date (aOR = 2.39; 99% CI, 2.12–2.68). When controlling for scanning and other factors, manufacturer, month vaccine was administered, and vaccine type were associated with variation in accuracy for both lot number and expiration date. Conclusion Two-dimensional barcode scanning shows promise for improving data accuracy of vaccine lot number and expiration date records. Adapting systems to further integrate with 2D barcoding could help increase adoption of 2D barcode scanning technology.
