 The hospitals were very dangerous places. We found that in order to have a safe and just culture, we needed to ensure people that there would not be retribution or fear of reporting incidents that happen. So we developed a what's called a just culture algorithm. In order to various risks in the hospital, we partnered with the patient safety movement in order to look at and have actionable solutions for 16 recognized hospital-acquired errors. It's exhilarating to know that the hard work that our doctors and nurses have put into these safety initiatives is starting to pay off. So that's wonderful. But we recognize that we really must continue the work. There is no reason why we can't get to zero for many years at every single hospital around the country for most of these critical events. We call these preventable errors because they are. First, it starts with the doctors and nurses caring. And next, we recognize that we all make mistakes every single day. So we have to put systems in place that help ensure that it makes it easier for us to do the right thing.
