Dr. Allan Goldman:

I will take that. I sort of began that earlier. Once the teams raised these concerns, we had a key meeting on 14 November and at that meeting we decided two things - first, that we would pause the kyphectomy operations, and rightly so, and, second, that we would do an internal review. Within a few days of regrouping with the executive team, we realised this went well beyond an internal review and to really get to the bottom of things, to understand, and to have independence and expertise, we needed to go outside CHI. We contacted Boston Children's Hospital, BCH,which I see as arguably the leading children's hospital in the world, and asked three questions. One, do we have a safety issue and what do we need to do about that? Two, are our outcomes in keeping with what should be expected internationally? Three, very importantly, what can we do to improve our systems to make them better? We engaged with BCH and we are very grateful to them for what they have done. It is a really important bit of information.
