Overview of proposed system to collect outcome data electronically. A mobile computer (top left panel) accepting flash card adapters and running the Palm OS is connected to a barcode wand scanner to input outcome data. The survey questions and their answer fields are presented on paper (top right panel). Barcodes are associated with specific answer fields. The layout can be adjusted (type face, presentation of information etc.). Once collected electronically on the mobile computer, the information can be transferred to a PC database.
