Background: Subarachnoid Hemorrhage (SAH) is associated with a high mortality rate and functional consequences. Several scales have been created in order to assess prognosis after SAH, and even though they have been widely studied, neither has achieved universal acceptance.
Objective: Validate different scales assessing the prognosis of patients with spontaneous SAH in a local hospital population.
Methods: A retrospective, cross-sectional study was conducted on patients admitted to the “Dr. Teodoro Maldonado Carbo” Hospital, diagnosed with spontaneous SAH, between 18 and 75 years. Descriptive statistics and Spearman correlation coefficient were calculated in order to evaluate the association of the Hunt and Hess, WFNS and Fisher Scales with functional outcome.
Results: Hunt and Hess Scale had a higher correlation (60,3%; p=0,000) with the functional outcome at discharge or death, compared to 55,3% (p=0,000) obtained by the World Federation of Neurological Surgeons Scale and 50% (p=0,000) by Fisher Scale. In addition, the Glasgow Coma Scale score (-58,4%; p=0,000), altered pupillary response (54,7%; p=0,000) and the need for invasive mechanical ventilation (73,8%; p=0,000) were factors associated with functional score.
Conclusion: Hunt and Hess Scale revealed a good correlation with the Rankin functional scale at discharge or death, and is superior to the other scales in evaluating the prognosis of patients with spontaneous subarachnoid hemorrhage.
