I wonder if the fact that so many were still be written in longhand had any influence here?  So much of healthcare is still a low tech business and it takes a lot more time to scan, transcript, etc. paper records versus entering information on the computer or doing a data transfer.  BD 

Most studies that are submitted to the FDA never make it into the medical journals that doctors consult to evaluate drugs’ overall safety and effectiveness, a study found.

Researchers looked at medicines approved between 1998 and 2000, and found that 394 out of a total of 909 studies submitted to FDA were published (they cut off their search at five years after approval).
