There has been some discussion on CanadianEMR about the best method to enter scanned data into an EMR. I have been using a Hewlett Packard 7450 with automatic document feeder. See image below - click on the image to enlarge.
I have scanned directly into .pdf file using software that comes standard with the HP scanner.
I tested the scanning speed and file size today by scanning two identical documents, first as a .pdf file and then as a .tif file. The scanning time for two pages was quite similar - 18 seconds for the .pdf and 21 seconds for the .tif, however the size of the files was markedly different.
The two page .pdf file was 100KB - see Test_Cytology_File_Feb_26_2003.pdf (application/pdf Object)
The .tif file saved as two individual pages. Each was 1MB (10 times larger) - see Test_Cytology_File_Feb_26_2003.tif (image/tiff Object)
You may view and print the files by clicking on the links above. The .pdf file is automatically created as an image file and I believe it to be quite adequate. If the scanner is capable, scanning directly into .pdf is simple and creates multi-page documents.
