While this is an interesting suggestion, the uses for this collection of data are.. questionable. I've tried in the past to intertwine my server-side roleplay with some sort of database, but it just ended up being a pointless complication. There weren't many uses for it, and for the few uses there were, it seemed like its existence only contributed a very small amount to the actual roleplay that took place.
So, I suggest you examine the uses for this medical information before it's implemented, and if it doesn't work, compile it yourself through the roleplay that takes place on the server. Assuming you have the endurance to run physicals on the entire crew, of course. G'luck.
