Study Shows 70% of Patients Lack Advance Directives before Elective Surgery (image) Regenstrief Institute Share Print E-Mail Caption Only 30% of pre-op patients reported having some form of Advance Directive documenting their wishes regarding emergency medical care. Only 16% had one on file in their electronic medical record (EMR) where a clinician could access it at the time of surgery. When there is no record of care preferences, families must decide what kind of emergency care their loved one receives.
