So what we went and did is had a talk to the DHBs and said, "Look, what are you doing to improve information access for these children and young people so that you can actually meet their health needs?" And one of the DHBs said, "Well, we've actually created this nice little system for coding in outpatients and we've got a couple of different broad, high-level diagnoses that we use." Another DHB said, "We've got this amazing system we've developed over the last few years. We've got about 20 to 30 of the most common codes that we've looked at and we consistently can monitor that over a period of time." Another one said, "Well, we actually use ICD-10, and so we've got access to thousands of codes." And that was fine, they could get all their own information, but then when they went to actually talk to their neighbours and say, "Well, how do we do some joint planning here?", there was no common information, there was no common language. And I think the other problem is then you couldn't aggregate that up at the national level to actually figure out what was going on.
