Sounds like things are getting better, note the last sentence in article.

Parkin said that for every previous injury, a racehorse's risk of fatal injury increases 30% based only on information submitted to the EID. The challenge, he said, is to get more information on each horse such as vet records, medical history, and training records.

I wanted to post some of the key points from todays summit.  Will look them up.  One was how important it is to run 2 yo's.

Oh you caught that!  Yes!

  "It really is critical to start exercising horses as 2-year-olds," Parkin said.

Let's look at that statement again.  He said "exercising" two-year-olds.  That's different from racing them.  He needs to clarify what he meant - in the statement as it stands, it sounds like he's referring to training rather than flat out competitive racing.

Thanks to Teresa's coverage today we have the answer:

Dr. Tim Parkin on Equine Injury Database: the earlier you start racing horses, the better for their bone health. Dismisses notion, based on research, that 2yo shouldn't race

I'm so glad they are continuing on with these studies.  They now have six years of data and can predict which horses are at risk and will begin using this data initially at 8 specific tracks, I believe that is I what I've read here.  I know that Finger Lakes already has a vet that has developed similar data and has been using predictors for the horses there.
