 you know, harm has impacted almost all of us. And I ask all you to reflect on either you or a loved one has been harmed. And as Sue pointed out, that's the tip of the harm. The harm to families is largely invisible, but equally devastating, leading to divorce, to trauma, to new people dropping out of jobs and mental illness, to bankruptcy. And we need to be looking at the whole picture because right now, healthcare harms too often, it costs too much, and it learns and improves too slowly. Patients are suffering needlessly. And so our clinicians and clinicians who make mistakes suffer deeply, as well as health systems.
