The role of Clinical Observation Scales in Determining Mortality for Cerebrovascular Diseases

Abstract

INTRODUCTION: Our objective is to point out the value of the different clinical observation scales in determining the mortality rates. METHODS: The information of 2.386 patients who were admitted to the neurology clinics of our hospital with the diagnosis of ischemic cerebrovascular disease (CVD) within 4 years was scanned from stroke database. The age, gender, and deaths of the patients were recorded. CVD clinical picture; evaluated by OCSP, NIHSS, GCS, SAPS, and mRs. RESULTS: The mean age of 2.386 cases included in the study was 65.7 years, and the death rate increased significantly as the age increased. There was no significant relationship between the death rate and gender (women 51.7%). According to the OCSP classification, the highest number of patients was in the PACI group (30.6%), while the group with the highest number of deaths was the TACI group (48.1%). The highest mortality rate was found in the group with NIHSS ≥23 (84.8%). In the group with GCS: 3–6 (10.8%), the mortality rate was the highest with 87.9%. Death occurred 82.8% of patients with a SAPS ≥14. Mortality rate was 21.9% in patients with a mRs ≥3. In comparison with the Chi-square test, all parameters except gender had a significant effect on death. (p<0.0001) As a result of logistic regression analysis, all parameters except mRs had a significant effect on death. DISCUSSION AND CONCLUSION: This article reviews both functional outcome measures and detailed neurological deficit measures used in stroke therapeutic efficacy study. While neurological measures predict mortality by detecting minor changes in neurological function, functional outcome measures seem to be more relevant to the patient's ability to function independently.
