The Glasgow Coma Scale and Full Outline of Unresponsiveness score evaluation to predict patient outcomes with neurological illnesses in intensive care units in West Bank: a prospective cross-sectional study. Acute Crit Care 2024; 39:408-419. [PMID: 39266276 PMCID: PMC11392694 DOI: 10.4266/acc.2024.00570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 07/21/2024] [Indexed: 09/14/2024] Open
Abstract
BACKGROUND Determining the clinical neurological state of the patient is essential for making decisions and forecasting results. The Glasgow Coma Scale and the Full Outline of Unresponsiveness (FOUR) Scale are commonly used tools for measuring behavioral consciousness. This study aims to compare scales among patients with neurological disorders in intensive care units (ICUs) in the West Bank. METHODS A prospective cross-sectional design was employed. All patients admitted to ICUs who met inclusion criteria were involved in this study. Data were collected from from An-Najah National University, Al-Watani, and Rafedia Hospital. Both tools were used to collect data. RESULTS A total of 84 patients were assessed, 69.0% of the patients were male, and the average length of stay was 6.4 days. The mean score on the Glasgow Coma scale was 11.2 on admission 11.6 after 48 hours, and 12.2 on discharge. The mean FOUR Scale score was 12.2 on admission, 12.4 after 48 hours, and 12.5 at discharge. CONCLUSIONS This study indicates that both the Glasgow Coma Scale and the FOUR scale are effective in predicting outcomes for neurologically deteriorated critically ill patients. However, the FOUR scale proved to be more reliable when assessing outcomes in ICU patients.

Abstract
OBJECTIVES We aimed to investigate the reliability and validity of the Glasgow Coma Scale (GCS) and the Full Outline of UnResponsiveness (FOUR) score used by nurses and physicians to assess the level of consciousness in patients admitted to intensive care units (ICUs) and emergency departments (EDs). REVIEW METHOD USED This systematic review was guided by the Cochrane Handbook for Systematic Reviews of Interventions and followed the reporting standards of the Preferred Reporting Items for Systematic Review and Meta-Analysis Statement. DATA SOURCES A systematic search was conducted using the following databases: CINAHL, MEDLINE, and EMBASE. REVIEW METHODS All authors performed the study selection process, data collection, and assessment of quality. The following psychometric properties were addressed: inter-rater reliability, internal consistency, and construct validity. RESULTS Six articles were included. The GCS and the FOUR scores demonstrated excellent reliability and very strong validity when used by nurses and physicians to assess the level of consciousness in patients admitted to the ICU and ED. The FOUR score demonstrated slightly higher overall reliability and validity than the GCS. CONCLUSION This systematic review indicates that the FOUR score is especially suitable for assessing the level of consciousness in patients admitted to the ICU and ED. The FOUR score demonstrated higher reliability and validity than the GCS, making it a promising alternative assessment scale, despite the GCS's longstanding use in clinical practice.

Abstract
Background Given the dearth of extensive research comparing the Glasgow Coma Scale with the Rotterdam scoring system for predicting mortality in trauma patients, this study was conducted to determine which scale provides a more realistic prediction of mortality in trauma patients after three months. Materials and Methods This observational study was performed at Kashani Hospital in Isfahan, Iran. Patients with TBI who were admitted between February 2022 and February 2023 were included in the study. Approval from the Ethical Committee of Isfahan University of Medical Sciences was obtained prior to conducting this study. Results We included 152 adult patients who completed the GOS-E and the QOLIBRI-OS three-month post-injury. The median age was 35 years (IQR = 17-70). Most patients 139 (91.4%) were classified as having a severe TBI. Conclusion The results of the present study showed that both the use of GCS and Rotterdam CT scores can be effective in predicting the three-month mortality and QOLIBRI-OS scores of patients, with the difference that the predictive power of the three-month Rotterdam CT score is greater than that of the GCS.

[PMID: 39070857 PMCID: PMC11279499 DOI: 10.4103/jets.jets_76_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 08/17/2023] [Accepted: 09/21/2023] [Indexed: 07/30/2024] Open
Abstract
Introduction Full outline of unresponsiveness (FOUR) score has advantages over Glasgow Coma Scale (GCS); as it can be used in intubated patients and provides greater neurological details. It has been studied mainly in the trauma and neuroscience setting. Our primary objective was to compare the FOUR versus GCS score as predictors of mortality at 30 days and poor functional outcome at 3 months among nontrauma patients in the emergency department (ED). Methods This prospective observational study was conducted on adult patients presenting with altered mental status (duration <7 days) in the ED (March 2019-November 2020). Data collection included demographic and clinical features, the GCS and FOUR scores, the feasibility of acquiring and interpreting FOUR on a Likert scale, duration of hospital stay, 30-day mortality, and functional outcome at 3 months on the modified Rankin Scale. Trained emergency medicine residents managing the patient collected the data. The area under receiver's operating characteristics curve (AUROC) was used to compare the accuracy of the GCS and FOUR scores in predicting outcomes. The FOUR score equivalent of GCS cutoffs for categorizing neurological impairment (mild, moderate, and severe) was also investigated. Results Two hundred and ninety-one patients were included, with a mean age of 50.3 years and 67.4% males. Most patients (40.2%) had altered mental status for 1-3 days and hepatic encephalopathy was the most common ED diagnosis. The mortality at 30 days was 66.7% (194 of 291), and 88% (256 of 291) of patients had poor functional outcomes at 3 months. The AUROCs for predicting 30-day mortality were similar for both the scores (GCS: 0.70, FOUR: 0.71, and the P value for difference: 0.9). Similarly, the AUROCs for predicting 3-month poor functional outcome were 0.683 and 0.669 using GCS and FOUR, respectively, with a nonsignificant difference (P = 0.82). The FOUR score strata of 14-16, 11-13, and 0-10 were found to be equivalent to the GCS scores of 13-15 (mild), 9-12 (moderate), and 3-8 (severe). The feasibility of acquiring and interpreting GCS and FOUR scores on the Likert scale was found to be "easy." Conclusion The FOUR score is similar to GCS in predicting mortality at 30 days and poor neurological outcomes at 3 months among nontrauma patients of ED. Moreover, it was found that the FOUR score is "easy" to assess and interpret by the emergency residents.

Abstract
BACKGROUND Delay in treatment of raised intracranial pressure (ICP) leads to poor clinical outcomes. Optic nerve sheath diameter (ONSD) by ultrasonography (US-ONSD) has shown good accuracy in traumatic brain injury and neurosurgical patients to diagnose raised ICP. However, there is a dearth of data in neuro-medical intensive care unit (ICU) where the spectrum of disease is different.
AIM To validate the diagnostic accuracy of ONSD in non-traumatic neuro-critically ill patients.
METHODS We prospectively enrolled 114 patients who had clinically suspected raised ICP due to non-traumatic causes admitted in neuro-medical ICU. US-ONSD was performed according to ALARA principles. A cut-off more than 5.7 mm was taken as significantly raised. Raised ONSD was corelated with raised ICP on radiological imaging. Clinical history, general and systemic examination findings, SOFA and APACHE 2 score and patient outcomes were recorded.
RESULTS There was significant association between raised ONSD and raised ICP on imaging (P < 0.001). The sensitivity, specificity, positive and negative predictive value at this cut-off was 77.55%, 89.06%, 84.44% and 83.82% respectively. The positive and negative likelihood ratio was 7.09 and 0.25. The area under the receiver operating characteristic curves was 0.844. Using Youden’s index the best cut off value for ONSD was 5.75 mm. Raised ONSD was associated with lower age (P = 0.007), poorer Glasgow Coma Scale (P = 0.009) and greater need for surgical intervention (P = 0.006) whereas no statistically significant association was found between raised ONSD and SOFA score, APACHE II score or ICU mortality. Our limitations were that it was a single centre study and we did not perform serial measurements or ONSD pre- and post-treatment or procedures for raised ICP.
CONCLUSION ONSD can be used as a screening a test to detect raised ICP in a medical ICU and as a trigger to initiate further management of raised ICP. ONSD can be beneficial in ruling out a diagnosis in a low-prevalence population and rule in a diagnosis in a high-prevalence population.

Abstract
AbstractRapid assessment of cerebral dysfunction is crucial for the management of patients in intensive care units. The Glasgow Coma Scale (GCS) evaluates eye, verbal, and motor responses, but is insufficient to effectively evaluate patients on mechanical ventilation, or who are unable to speak. The Full Outline of Unresponsiveness (FOUR) score includes additional information such as brainstem reflexes and respiratory status to provide a more complete clinical assessment. In this study, we aimed to compare the FOUR score with GCS in the assessment of patients with coma. This prospective study included patients between 1 month and under 18 years of age, who were hospitalized in the pediatric intensive care unit due to risk of coma or ongoing impairment of consciousness between May 2018 and June 2019. Information regarding FOUR scores, GCS values, patient demographics, duration of hospitalization, requirement for mechanical ventilation, and patient comorbidities were recorded and analyzed. Among the 80 patients included in the study, a statistically significant correlation was found between (low) GCS and FOUR scores during admission, and mortality and requirement for mechanical ventilation. Monitoring the level of consciousness is important in pediatric intensive care units and may be predictive of the course and disease outcome. Similar to the GCS, the FOUR score is a good indicator for predicting mortality and requirement for mechanical ventilation.

Abstract
Background Predicting the mortality and prognosis of patients with stroke is one of the commonly studied topics. Various scoring systems have been used in this regard. One of them is the Full Outline of UnResponsiveness (FOUR) score. In this study, we aimed to investigate the utility of the FOUR scores in terms of their ability to predict hospital stay duration and mortality in patients who were diagnosed with ischemic stroke upon their admission to the emergency department. Methods Our study is a prospective observational study. Patients who were admitted to the emergency department of a tertiary hospital and diagnosed with ischemic stroke between August 1, 2020, and August 1, 2021, were included in the study. The inclusion criteria were as follows: being over the age of 18, being diagnosed with ischemic stroke, having symptoms that started within the last 48 hours, and patient consent approved by the patients themselves or their relatives. The patients were divided into two groups according to the FOUR scores (FOUR score = 16 and FOUR score < 16). Patients’ demographic information, vital parameters, symptoms, time to admission, comorbidities, laboratory parameters, length of hospitalization, mortality, and Glasgow Coma Scale (GCS), FOUR, and National Institutes of Health Stroke Scale (NIHSS) scores were recorded. Results A total of 79 patients were included in the current study, of which 47 (59.5%) were male. The patients included in the present study had a mean age of 66 ± 13 years. When the two groups of patients with a FOUR score of 16 and a FOUR score of below 16 were compared, the mean platelet count was found to be 248 ± 70 × 103/L in the former group and 170 ± 84 × 103/L in the latter (p = 0.004). Sixty-five (91.5%) of the patients in the group with a FOUR score of 16 and three (37.5%) of the patients in the group with a FOUR score of less than 16 stayed for more than six hours in the hospital (p < 0.001). When the patients were evaluated for intensive care unit (ICU) admission rates, five (62.5%) patients with a FOUR score of <16 were admitted to the ICU. This rate was 2.8% (n = 2) in the group of patients with a FOUR score of 16 and was found to be significantly lower (p < 0.001). Conclusion The FOUR score was found to be useful in predicting the ICU admission rate of patients with ischemic stroke. It has also been shown that the admission time was shorter in patients with a lower FOUR score, and platelet counts were also lower in this group.

Abstract
Background Advanced age is one of the key risk factors for mortality and morbidity in intensive care units. The full outline of unresponsiveness (FOUR) score has been developed and introduced to address the limitations of the Glasgow Coma Scale (GCS). The current study aimed to evaluate the ability of the FOUR score in predicting the outcomes (survivors, nonsurvivors). Materials and methods This observational study of 168 consecutive elderly patients admitted to medical intensive care during the 14 months carried out prospectively. FOUR score in the 24, 48, and 72 hours of admission, and demographic characteristics of all elderly patients were calculated, then recorded. The receiver operating characteristic (ROC) curve, logistic regression, and Hosmer-Lemeshow test were used (95% confidence interval) for statistical analysis. Results FOUR scores in 24, 48, and 72 hours between survivors and nonsurvivors (p <0.0001, p <0.0001, and p <0.0001, respectively) were statistically different. The discrimination power of FOUR score 24 hours of admission was excellent [area under ROC (AUC): 85.7% [standard error (SE)]: 2.8%]; it was acceptable for 48 and 72 hours of admission [AUC: 76.3% (SE: 3.6%), AUC: 75/0% (SE: 3.8%), respectively]. The FOUR score of 24 and 48 hours (x2 = 10.06, p = 0.261, x2 = 6.82, p = 0.448, respectively) showed acceptable calibration. Conclusions The FOUR score is a suitable scoring system for prognostication of outcomes in critically ill elderly patients. The FOUR score 24 hours of admission was superior in terms of discrimination power than 48 and 72 hours, but better calibration power belonged to FOUR score 48 hours.

Abstract
BACKGROUND The Glasgow Coma Scale was developed in 1974 as an injury severity score to assess and predict outcome after traumatic brain injury. The tool is now used to score depth of impaired consciousness in patients with and without traumatic brain injury. However, evidence supporting the use of the Glasgow Coma Scale in the latter group is limited. OBJECTIVE To assess Glasgow Coma Scale score on hospital admission as a predictor of outcome in patients without traumatic brain injury. METHODS This was a secondary analysis of prospectively collected data from 3507 patients admitted to 4 hospitals between October 2015 and October 2019. Patients with a primary diagnosis of traumatic brain injury were excluded from this study. RESULTS The mean age of the 3507 participants in the study was 57 years. Participants were primarily female (52%), White (77%), and non-Hispanic (89%). On admission, 90% of patients had a modified Rankin Scale score of 0 to 3 and 72% had a Glasgow Coma Scale score of 13 to 15 (mild injury). Generalized estimating equation modeling indicated that admission Glasgow Coma Scale score did not predict modified Rankin Scale score at discharge in patients not diagnosed with traumatic brain injury (Glasgow Coma Scale score <8: z = -7.89, P < .001; Glasgow Coma Scale score 8-12: z = -4.17, P < .001). CONCLUSIONS The Glasgow Coma Scale is not recommended for use in patients without traumatic brain injury; clinicians should use a more appropriate and validated clinical assessment instrument for this patient population.

Abstract
BACKGROUND Metabolic encephalopathy (ME), central nervous system (CNS) infections, and stroke are common causes of reduced level of consciousness in Uganda. However, the prognostic utility of changes in the daily measurements of the Full Outline of Unresponsiveness (FOUR) score and Glasgow Coma Scale (GCS) score in these specific disorders is not known. METHODS We conducted secondary analyses of data from patients who presented with reduced level of consciousness due to CNS infections, stroke, or ME to a tertiary hospital in Uganda. Patients had FOUR/GCS scores at admission and at 24 and 48 h. We calculated a change in FOUR score (ΔFOUR) and change in GCS score (ΔGCS) at 24 and 48 h and used logistic regression models to determine whether these changes were predictive of 30-day mortality. In addition, we determined the prognostic utility of adding the admission score to the 24-h ΔFOUR and 24-h ΔGCS on mortality. RESULTS We analyzed data from 230 patients (86 with ME, 79 with CNS infections, and 65 with stroke). The mean (SD) age was 50.8 (21.3) years, 27% (61 of 230) had HIV infection, and 62% (134 of 230) were peasant farmers. ΔFOUR at 24 h was predictive of mortality among those with ME (odds ratio [OR] 0.64 [95% confidence interval {CI} 0.48-0.84]; p = 0.001) and those with CNS infections (OR 0.65 [95% CI 0.48-0.87]; p = 0.004) but not in those with stroke (OR 1.0 [95% CI 0.73-1.38]; p = 0.998). However, ΔGCS at 24 h was only predictive of mortality in the ME group (OR 0.69 [95% CI 0.56-0.86]; p = 0.001) and not in the CNS or stroke group. This 24-h ΔGCS and ΔFOUR pattern was similar at 48 h in all subgroups. The addition of an admission score to either 24-h ΔFOUR or 24-h ΔGCS significantly improved the predictive ability of the scores in those with stroke and CNS infection but not in those with ME. CONCLUSIONS Twenty-four-hour and 48-h ΔFOUR and ΔGCS are predictive of mortality in Ugandan patients with CNS infections and ME but not in those with stroke. For individuals with stroke, the admission score plays a more significant predictive role that the change in scores.

Abstract
We assessed the clinical significance of mismatch negativity (MMN) in predicting the awakening of comatose patients with severe brain injury. The clinical data of patients with severe brain injury, admitted to the neurosurgical intensive care unit of Xiangya Hospital of Central South University from July 2018 to March 2020, who underwent auditory MMN examinations within 28 days after coma onset, were reviewed. Correlations between clinical factors and prognosis [Glasgow Outcome Scale (GCS) for 3 mo] were analyzed. Fifty-three patients were included; 37 (69.8%) had favorable outcomes. A univariate analysis revealed the Glasgow Coma Scale (GCS) and absolute MMN amplitudes at electrodes Fz and Cz were significantly correlated with prognosis. Only GCS scores and MMN amplitude at Fz were independent predictors in multivariate logistic regression analysis (area under the curve 0.744 vs. 0.753, respectively); both combined, improved accuracy to 84.6%. MMN amplitudes at Fz were dichotomized at a value of 1.08 μV with a sensitivity and specificity of 81.1% and 68.7%, respectively, for predicting comatose patients' awakening. In conclusion, MMN amplitude at Fz is a reliable prognostic indicator for comatose patients with severe brain injury; the prediction value improved when combined with GCS. Thus, an event-related potential component with a clear site and cutoff value may support prognostication in severe brain injury.NEW & NOTEWORTHY Mismatch negativity (MMN) can assess the prognosis of comatose patients after severe brain injury, especially for MMN amplitude. In addition, MMN analysis at electrode Fz best predicts recovery of consciousness in patients with severe brain injury. Importantly, a quantitative approach (cutoff value of 1.08 μV) may improve the use of MMN for prognostication.

Abstract
BACKGROUND The Full Outline of Un-Responsiveness Score (FOURs) is a scale for clinical assessment of consciousness that was introduced to overcome disadvantages of the widely accepted Glasgow Coma Scale (GCS). OBJECTIVE To carry out a systematic review and critical analysis of the available literature on the clinical application of FOURs and perform a comparison to GCS, in terms of reliability and predictive value. METHODS Initial search retrieved a total of 147 papers. After applying strict inclusion criteria and further article selection to overcome data heterogeneity, a statistical comparison of inter-rater reliability, in-hospital mortality and long-term outcome prediction between the two scales in the adult and pediatric population was done. RESULTS Even though FOURs is more complicated than GCS, its application remains quite simple. Its reliability, validity and predictive value have been supported by an increasing number of studies, especially in critical care. A statistically significant difference (p = .034) in predicting in-hospital mortality in adults, in favor of FOURs when compared to GCS, was found. However, whether it poses a clinically significant advantage in detecting patients' deterioration and outcome prediction, compared to other scaling systems, remains unclear. CONCLUSIONS Further studies are needed to discern the FOURs' clinical usefulness, especially in patients in non-critical condition, with milder disorders of consciousness.
