Prehospital GCS as a Predictor of Outcome after Acute Ischemic Stroke (P06.238)

Design/Methods: Adult patients presenting to the emergency department who had an ultimate discharge diagnosis of ischemic stroke were included in this cohort. The prehospital GCS was obtained from ambulance records in real time, performed by EMS crew. The outcomes of interest were stroke severity as measured by NIHSS, occurrence of endovascular intervention, functional outcome measured by modified Rankin score, and death within 90 days. Logistic regression analyses using JMP 8.0 for the mac performed to assess for correlation. Results: There were upto 4 pre-hospital GCS collected in the cohort (n=145), depending on transportation times. For this study, the first pre-hospital GCS, obtained at the time of first patient contact, was used. GCS Distribution followed a non parametric pattern; the median GCS was 15, range 3-15, IQR 12.5-15. The median and IQRs were: pulse 78 (70-90), sBP 151 (133-176), dBP 83 (72-97), MAP 106 (95-121). Table 1 depicts the number of patients with each GCS, and their median time of arrival to the ED after symptom onset. On univariate analysis, prehospital GCS was significantly correlated with each of the outcome measures of interest. Patients with lower GCS were significantly more likely to have more severe strokes (P Conclusions: The prehospital GCS appears to be a good predictor of stroke severity, and thus correlates for higher likelihood of endovascular intervention. Similarly, the prehospital GCS also correlates well with functional outcome at hospital discharge and death within 90 days. Disclosure: Dr. Weaver has nothing to disclose.
