Some of those I addressed in my opening statement, things like personal protective equipment availability in the supply chain, rapidly planning for increased capacity, ramping down surgeries, trying to discharge patients, developing an assessment centre. There were a lot of medical unknowns. This was a novel virus; it had never been seen before. There was a lot of fear among our staff and in the communities, which we had to address, and we had no known treatments.
You test and try on the fly. We used an awful lot of international experience to guide us, and we certainly collaborated a great deal with colleagues.
I think those are the main challenges. Human resource-wise, I think we did quite well.
