Survey: Patient harm tops hospital’s concern, but most lack proper data to fix it

You could easily prove patient harm to every single stroke patient  by doing MRI scans on a daily basis post-stroke and seeing the progression of the dead area. But your hospital doesn't even know about this problem unless YOU tell them about it. And some typeA personality will eventually sue a stroke hospital for that reason. Standard of care will be unlikely to be a valid defense.
