Observational Study on Mortality and Outcome of Patients Hospitalized for Subarachnoid Hemorrhage of Aneurysmal Origin in Martinique Between 2013 and 2021

Observational Study on Mortality and Outcome of Patients Hospitalized for Subarachnoid Hemorrhage of Aneurysmal Origin in Martinique Between 2013 and 2021

The aim of our study is to analyze mortality and sequelae of subarachnoid hemorrhage of aneurysmal origin in hospitalized patients in Martinique. Predictive factors of poor prognosis will also be analyzed.

Subarachnoid hemorrhage is an uncommon pathology in the general population, with a worldwide incidence of 9 per 100,000 people/year, but with a non-negligible risk of sequelae in terms of impairments, activity limitations and participation restrictions of around 30%. Mortality remains high at 40%, despite increasingly specialized care.

In addition, there are a number of objective, rapid assessment scores for autonomy and impairments, notably the modified Rankin score, which is not specific to subarachnoid hemorrhage, but which enables the study of patients' perceived quality of life. Certain factors predictive of bad patient outcome are known in the literature, but have been little studied in the population of Martinique.

Inclusion Criteria:

• Adult (≥18 years) patients,
• Admitted to University Hospital of Martinique with subarachnoid hemorrhage of aneurysmal origin between 01/01/2013 and 31/12/2021,
• Informed patient/next-of-kin/treating physician consent for research participation.

Exclusion Criteria:

• Other causes of subarachnoid hemorrhage of non-aneurysmal origin (traumatic, arteriovenous malformation, cerebral tumor, cerebral thrombophlebitis).
