Assessing validity and reliability of glasgow coma scale and full outline of unresponsiveness score

Abstract

Background: Monitoring accurately the patient’s level of consciousness is vital to the management and prognosis. Glasgow coma scale (GCS) the gold standard tool is associated with the discrepancy in scoring eye component and the non-usability of verbal component. The full outline of unresponsiveness (FOUR) score a recently validated tool surpasses the deficits of the GCS tool, examined for its accuracy in assessment, and predicting the outcomes of patients with altered level of consciousness. Aim: To evaluate the predictive value of the GCS and FOUR score tool in relation to the outcomes among patients in altered level of consciousness. Design: A systematic review. Data sources: The MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Cochrane Central Register of Controlled Trials (Cochrane Library), EMBASE, PsycINFO and Web of Science were searched “between” 2011 – 2021 and presented using PRISMA. Review methods: Research studies, which compared the GCS and FOUR score in predicting the outcome of patients with altered level of consciousness, were included. Results: 23 studies, which compared the GCS and FOUR score, were included in this review based on the inclusion criteria.
