Quantitative and Qualitative Comparison of Text-Based and Graphical User Interfaces for Computerized Provider Order Entry.

Limited prospective data exist that define advantages and disadvantages of text-based versus graphical user interfaces in Computerized Provider Order Entry (CPOE). We created a single set of admission orders in both formats and, using a randomized crossover design, assessed the usage and perceptions of the two interfaces by 51 physicians during the first six weeks (2 week blocks of one format, then the alternative, then free choice) following implementation in a postsurgical unit.
