ABSTRACT

Background:

Sixty-nine million people suffer from traumatic brain injury (TBI) each year and TBI is the most common cause of subarachnoid hemorrhage (SAH). Traumatic SAH has been described as an adverse prognostic factor leading to progressive neurological deterioration and an increase in morbidity and mortality, but there are a limited number of studies which evaluate recent trends in the diagnostic and management of SAH in the context of trauma.

Objective:

The objective of this scoping review is to understand the extent and type of evidence in relation to the diagnostic criteria and management of traumatic subarachnoid hemorrhage.

Methods:

This scoping review will be conducted in accordance with the JBI methodology for scoping reviews. A three-step search strategy (initial limited search in PubMed and Scopus databases, a main search of EMBASE, Web of Science, EBSCO, MEDLINE, and manual searches of reference lists of included articles) will be utilized. The search will be limited to studies with human participants and published in English, Spanish, and French between 2005-2020. This review will consider studies of adolescent and adult patients who have suffered from SAH secondary to trauma. Study selection will be performed by two authors in a two-phase process; if any disagreement arises, a third author will be consulted. Data to be extracted from each study will include population, intervention, comparator and outcome measures and a summary of findings. Citation screening, full-text review, risk of bias assessment, and extraction of study characteristics and outcomes will be carried out using a web-based software platform that streamlines the production of scoping reviews.

Results:

Ethics approval is not required for this systematic review, as there will be no patient involvement. The search for this systematic review commenced in December 2020, and we expect to publish the findings in early 2021. The plan for dissemination is to publish review findings in a peer-reviewed journal and present findings at conferences that engage the most pertinent stakeholders.

Conclusions:

This scoping review will serve as an initial step in providing more evidence for healthcare professionals, economists and policymakers in order that they might devote more resources towards this significant problem affecting both health and economic outcomes worldwide.
