title: Model analysis of time duration in a medication order entry system with attention to do-medication orders.
abstract: To investigate the relative time length needed for a medication computer order entry in comparison with the handwritten prescription system, we made a model, focusing our attention on the "do-medication order entry function." In the model analysis, we conducted a statistical analysis using the Nagoya University Hospital Information System. From the results and our model, if the time needed to make one (drug) item medication order entry is less than 1.9-3.0 times the time needed for handwriting one item prescription, computer order entry is faster on average.
