This wasn't announced, but medical characters (First Aid or Physician) - if you scan someone's code now, if you read the description, it'll give you an estimate as to how bad the character's wounds are. The better your skill, the more accurate you are. If you have Diagnostic Medicine, you have the most accurate one.
Apparently, people didn't notice this. Since they are requesting the feature in their exit surveys. Well, wish granted - though we didn't really announce it.
