“Encephalopathy Only Stroke Codes” (EoSC) Rarely Result in Stroke as Final Diagnosis

Figure 1

Study Definitions. Schematic showing study definitions. Stroke codes are first defined as encephalopathy only (EoSC) or other stroke codes (non-EoSC). EoSC were put into two different definitions based on NIHSS: one with only mental status changes (Definition 1) and another allowing for symmetric motor findings (Definition 2). Under each definition there is a final diagnosis of stroke (EoSC CVA+) which is compared to non-EoSC stroke positive diagnoses (non-EoSC CVA+).
