When is a hospital considered at fault for a patient’s injury?

A hospital is considered at fault for a patient’s injury when they violate the standard of care. So if any of the hospital’s employees providing medical care and treatment do something that they shouldn’t do, that’s a violation of the standard of care, or if they fail to so something that they should do. For example, when a nurse gives a transfusion of blood, the standard of care requires her to monitor that patient to get the vital signs before they give the transfusion, and then get them at various times following to be sure that they’re not having an adverse reaction. If a nurse doesn’t do that and there is an adverse reaction, you can sue the hospital.
