Assume that an ambulance brought Cindy Roe to the emergency department of Grace Medical Center. She makes the decision to leave the hospital without receiving treatment. The attending physician and the hospital staff offer Cindy medical examination and treatment within the hospital before she leaves. Cindy refuses treatment, refuses to sign an informed consent, and they let her go. The physician/hospital most likely has violated EMTALA
If the ambulance brought Cindy to the hospital she must need attention immediately. So, then the hospital has to treat her.
