Swiss Study on Subarachnoid Hemorrhage

This registry was created to assess management parameters of patients treated for aneurysmal subarachnoid hemorrhage in Switzerland. All Swiss hospitals with a neurosurgery department, an intensive care unit and an interventional neuroradiology team that treat neurovascular emergencies participate in the registry. Clinical parameters are entered into a common database. This database will provide (1) a nationwide assessment of the current standard of care and (2) the outcomes for patients in Switzerland including neuropsychological assessments.

About this study

Overview:

The management of aneurysmal subarachnoid hemorrhage (aSAH) in Switzerland has not been assessed on a national level to date. The investigators united all comprehensive neurovascular care centres in Switzerland to create a registry for aSAH. This registry helps collect clinical and management data from different centres and pools it in one common database. It may provide referring caregivers and healthcare providers with a critical tool to assess the quality of care in a disease which has a high socio-economic burden. Moreover, it may serve as a tool to foster scientific collaboration and address a number of remaining questions about the management of aSAH in the future. Regarding SAH, data from the federal statistics bureau of Switzerland are based strictly on ICD-10 codes provided by hospitals and show an estimate of 13 per 100,000 in a population of roughly 8 million (http://bfs.admin.ch). These numbers, however, are not referring to aneurismal SAH exclusively and thus exceed the numbers which the investigators expect to obtain. The goal is to obtain complete recruitment of SAH patients throughout Switzerland, and the goal is therefore that assessment of incidence will be performed later on.

Data management:

Data is entered into a central online database created by the Secutrial platform. This platform is provided by the University Hospital of Geneva's Clinical Research Unit. The database disposes of an audit-trail capacity. Local principal investigators are responsible for data-cross check and quality management. Source data verification is performed by investigators on site who address missing data. Regular meetings are held to discuss data patency.

The platform automatically provides a report on recruitment progress.

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients admitted with a proven diagnosis of aneurysmal subarachnoid hemorrhage.

Exclusion criteria

  • Patients in whom the source of haemorrhage could not be identified (angiogram-negative SAH) or SAH with other causes than cerebral aneurysms.

Treatment and study plan

Observational/ no intervention

Other

Primary outcomes

  1. Functional outcome as assessed by the modified Rankin scale

    Time frame: 5 years after hemorrhage

    The modified Rankin scale is used to represent the level of disability and is divided into 7 categories (0-6). The scale runs from 0-6, running from perfect health without symptoms to death.

    0 - No symptoms.

    • - No significant disability. Able to carry out all usual activities, despite some symptoms.
    • - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.
    • - Moderate disability. Requires some help, but able to walk unassisted.
    • - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.
    • - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.
    • - Dead.
