Subarachnoid hemorrhage (SAH) is a critical and often life-threatening condition that necessitates prompt diagnosis and treatment. This study aims to evaluate the clinical outcomes of SAH patients utilizing data from the Philippine Neurological Association (PNA) One Database (PNA1DB) - Stroke, the largest stroke registry in the Philippines. A retrospective analysis was conducted on SAH cases recorded from 2021 to 2024. The primary outcomes measured included mortality rates, functional recovery, and complications. Secondary outcomes assessed the impact of demographic variables, such as age and sex, and clinical parameters, including initial Glasgow Coma Scale (GCS) scores and comorbid conditions, on patient prognosis. Out of 560 identified cases of subarachnoid hemorrhage (SAH), only 153 patients (27.3%) received treatment. Among these, 110 patients (19.6%) underwent aneurysm clipping, while 43 patients (7.7%) underwent coiling. Functional recovery, assessed using the modified Rankin Scale (mRS), revealed that 244 survivors (43.5%) achieved favorable outcomes (mRS 0-2) at discharge. Unfortunately, 181 patients (32.3%) died during their hospital stay. Key factors associated with poor outcomes included advanced age, low initial Glasgow Coma Scale (GCS) scores, and the presence of comorbidities such as hypertension and diabetes, as well as other determinants like smoking. This study underscores the critical need for early intervention and tailored management strategies in SAH patients to improve survival and functional outcomes in the Philippine context.
