Dr. Allan Goldman:

Once you know there is a problem with that, then you need to start investigating it. In regard to these children with spina bifida, where we saw an increase in these complications, as I said earlier, when we started to increase our activity and we had discussions with the surgeons, they certainly made it very clear that, based on their past experience, as we increased our activity, particularly with complex patients, we would see an increase in infection rates and an increase in returns to theatre.
