Despite the recent advances in its early detection, diagnosis, and proper treatment, the outcome of patients experiencing aneurysmal subarachnoid hemorrhage (aSAH) remains poor. It is well known that cerebral vasospasm is the most troublesome complication of aSAH, while delayed cerebral ischemia related to cerebral vasospasm constitutes the major cause of unfavorable outcomes in patients with aSAH. The need for evidence-based guidelines is of great importance for the prevention, early detection, and efficient management of aSAH-induced vasospasm. Moreover, guidelines provide young physicians with a valuable tool for practicing defensible medicine. However, the methodology, clinical applicability, reporting clarity, and biases of guidelines must be periodically assessed. In this study, the authors sought to assess the reporting clarity and methodological quality of published guidelines and recommendations.<\/jats:p>\n <\/jats:sec>\n \n METHODS<\/jats:title>\n A search was performed in the PubMed, Scopus, and Web of Science databases. The search terms used were \u201cclinical practice guidelines,\u201d \u201crecommendations,\u201d \u201cstroke,\u201d \u201csubarachnoid hemorrhage,\u201d and \u201cvasospasm\u201d in all possible combinations. The search period extended from 1964 to September 2021 and was limited to literature published in the English language. All published guidelines and recommendations reporting on the diagnosis and management of vasospasm were included. Studies other than those reporting guidelines and recommendations were excluded. The eligible studies were evaluated by three blinded raters, employing the Appraisal of Guidelines for Research & Evaluation II (AGREE-II) analysis tool.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n A total of 10 sets of guidelines were evaluated in this study. The American Heart Association\/American Stroke Association issued guidelines found to have the highest methodological quality and reporting clarity, followed by the European Stroke Organization guidelines and the English edition of the Japanese guidelines issued by the Japanese Society on Surgery for Cerebral Stroke. The interrater agreement was moderate in the current analysis.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n These findings support the idea that improvement of currently existing guidelines is feasible in the following domains: the rigor of guidelines and recommendations development, clinical applicability, editorial independence, and stakeholder involvement. Furthermore, periodic updating of published guidelines requires improvement in the future.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2021.12.focus21649","type":"journal-article","created":{"date-parts":[[2022,3,1]],"date-time":"2022-03-01T07:20:16Z","timestamp":1646119216000},"page":"E11","source":"Crossref","is-referenced-by-count":1,"title":["Methodological assessment of guidelines for the diagnosis and management of cerebral vasospasm using the AGREE-II tool"],"prefix":"10.3171","volume":"52","author":[{"given":"Anastasia","family":"Tasiou","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital of Larissa, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandros G.","family":"Brotis","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital of Larissa, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christos","family":"Tzerefos","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital of Larissa, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xanthoula","family":"Lambrianou","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital of Larissa, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kostas N.","family":"Fountas","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital of Larissa, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"2","key":"b1","series-title":"Radiology","doi-asserted-by":"publisher","first-page":"423","DOI":"10.1148\/radiology.208.2.9680571","article-title":"Subarachnoid hemorrhage: aneurysm detection and preoperative evaluation with CT angiography","volume":"208","author":"Velthuis BK","year":"1998","unstructured":"Velthuis BK, Rinkel GJ, Ramos LM, Subarachnoid hemorrhage: aneurysm detection and preoperative evaluation with CT angiography.
