I would start simple:
What kind of fence caused a rotational fall at each event where one occurred?
What was the speed set for that course where it happened?
As I see it, all the other variables of horse and rider training, fitness, ability, weather, footing, etc. are subordinate to the two issues above. They are also pretty much the only two factors under the control of Event organizers–speed and course design. The other variables are up to the riders and trainers and are so subjective they could never be measured, mandated or enforced. No equestrian sport or any other depending on personal judgment can EVER be 100% safe.[/QUOTE]
No, the other data is stuff I think it’d be potentially wise to collect going forward, since like I said, it would be hard to get past data accurately. There are people who are experts on such things who could probably determine which things it’s worth taking the time to log, and how to design a survey to properly capture the desired information with an acceptable chance of accuracy, so TPTB should be talking to them about what information should be collected. There is likely a ‘sweet spot’ in terms of effort to collect versus usefulness of information collected, and probably there are people who figure that kind of thing out on a regular basis also. 
Whatever, though, even if they’re just keeping much more basic information, they really do need to start tracking TODAY and do so PROPERLY with it all going into a central database that people know about and can gain access to, so people can, you know, ACTUALLY DO RESEARCH with it. If TPTB are gathering information but not making it accessible anywhere and have no plans to do so, then they might as well just not bother gathering it. (And when I say accessible I do not mean everyone needs to be able to find it with google. But someone who wants to do a statistical analysis with reasonable credentials for doing so should be able to apply and get access to the data they need. I’m moderately sure this is a thing that happens in other areas already - you have to have certain qualifications and/or jump through certain hoops to access collected data.)
I would like to see also a good internationally applied (HAH) incident report form so that when things do happen, we make sure we learn as much as possible. And some of what we learn may easily be things that are difficult to mandate or enforce, but if it is a big enough issue then you get the equestrian media talking about it, and add it to trainer education classes, and so on, so that at least SOME people will make use of it. (And depending on what it is, you may even see it changing the behavior of people like pros - if we found out risk of accident goes up significantly with each additional horse you ride on the day even once you account for simply being in the saddle more, then even if the pro doesn’t change behavior, horse owners might start pulling horses from pros that have larger strings, so it doesn’t end up that THEIR horse is the one who runs fifth on the day and ends up having to be euthanized due to a bad fall, etc.)
