Clinical assessment and short-term mortality prediction of older adults with altered mental status using RASS and 4AT tools. Am J Emerg Med 2024; 75:14-21. [PMID: 37897915 DOI: 10.1016/j.ajem.2023.10.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 10/07/2023] [Accepted: 10/08/2023] [Indexed: 10/30/2023] Open
Abstract
BACKGROUND Altered mental status (AMS) in older adults is a common reason for admission to emergency departments (EDs) and usually results from delirium, stupor, or coma. It is important to proficiently identify underlying factors and anticipate clinical outcomes for those patients. AIM The primary objective of this study was to reveal and compare the clinical outcomes and etiologic factors of older patients with delirium, stupor, and coma. The secondary objective was to identify the 30-day mortality risk for those patients. METHOD The study was conducted as prospective and observational research. We included patients aged 65 years and older who presented with new-onset neurological and cognitive symptoms or worsening in baseline mental status. Patients who presented no change in their baseline mental status within 48 h and those who needed urgent interventions were excluded. Selected patients were assessed using RASS and 4AT tools and classified into three groups: stupor/coma, delirium, and no stupor/coma or delirium (no-SCD). Appropriate statistical tests were applied to compare these 3 groups. The 30-day mortality risks were identified by Cox survival analysis and Kaplan-Meier curve. RESULTS A total of 236 patients were eligible for the study. Based on their RASS and 4AT test scores: 56 (23.7%), 94 (40.6%), and 86 (36.4%) patients formed the stupor/coma, delirium and no-SCD groups, respectively. There was no statistical difference in the three groups for gender, mean age, and medical comorbidities. Neurological (34.7%), infectious (19.4%), and respiratory (19.0%) diseases were the leading factors for AMS. Post-hoc tests showed that CCI scores of the delirium (6, IQR = 3) and stupor/coma (7, IQR = 3) groups were not significantly different. The 30-day mortality rates of stupor/coma, delirium, and no-SCD groups were 42.%, 15.9%, and 12.8%, respectively (p < 0.005). The hazard ratio of the stupor/coma group was 2.79 (CI: 95%, 1.36-5.47, p = 0.005). CONCLUSION AMS remains a significant clinical challenge in EDs. Using the RASS and 4AT tests provides benefits and advantages for emergency medicine physicians. Neurological, infectious, and respiratory diseases can lead to life-threatening mental deterioration. Our study revealed that long-term mortality predictor CCI scores were quite similar among patients with delirium, stupor, or coma. However, the short-term mortality was significantly increased in the stupor/coma patients and they had 2.8 times higher 30-day mortality risk than others.

Abstract
BACKGROUND Disorders of consciousness including coma in non-trauma patients can be caused by a wide variety of pathologies affecting the central nervous system. They represent a frequent challenge in emergency medicine and are combined with a very high in-hospital mortality. Hence, early treatment of these patients is vital and increases the likelihood of a good outcome.
AIM To identify the causes of altered consciousness presentation to the Emergency Department at Suez Canal University Hospital.
METHODS This was a descriptive cross-sectional study conducted on 87 patients with acute non-traumatic disturbed level of consciousness (DLOC) at the Emergency Department.
RESULTS The mean age of the studied patients was 60.5 ± 13.6 years. Among them, 60% were males and 40% were females. The most common cause of acute non-traumatic DLOC was systemic infection, such as sepsis and septic shock (25.3%), followed by respiratory causes (24.1%) and neurological causes (18.4%).
CONCLUSION The most common cause of acute non-traumatic DLOC was systemic infections followed by respiratory and neurological causes.

Abstract
Background This study aimed at evaluating the clinico-etiological profile of altered mental status (AMS) among elderly patients and making recommendations regarding management based on etiologies, thereby improving both morbidity and mortality outcomes. Materials and Methods This retrospective observational study was conducted in a teaching cum tertiary care hospital. Two years data (from July 2017 to June 2019) were extracted from the medical records section, and 172 eligible participants were analyzed using descriptive statistics for clinical outcomes, demographic profiles, and various etiological factors. Results A total of 1784 elderly inpatients (age >60 years) were screened from the records, and 172 eligible elderly AMS patients were found eligible for the study. The male elderly population consisted of 110 (63.95%), and the female elderly was 62 (36.04%). The mean age of the study population was 67.82 years. The etiological factors of AMS in the study population were neurological - 47.09% (n = 81), infection - 30.23% (n = 52), metabolic/endocrine - 16.27% (n = 28), pulmonary - 2.32% (n = 4), fall - 1.74% (n = 3), toxic cause - 1.16% (n = 2), and psychiatric illness - 1.16% (n = 2). The total mortality rate was 9.30% (n = 16). Conclusion The main etiological factors of AMS in the elderly population were predominantly of neurological, septic, and metabolic causes. These factors were preventable and treatable by training physicians, staff (as most of the physicians in the developing countries are not trained in managing this fragile group of population with multiple comorbidities), and by decentralizing geriatrics health-care setups.

Abstract
New-onset altered level of consciousness (ALC) is a challenge in real-world clinical practice. Although its presentation is nonspecific and its etiology is intricate, the term ALC is frequently used in the emergency room (ER). This study aimed to clarify and classify the etiologies and outcomes of the ALC in the ER. We retrospectively investigated ALC patients in the ER of four tertiary referral centers from February 2018 to January 2020. The etiology of ALC was comprehensively analyzed by a consortium of university professors, board-certified clinicians in neurology, emergency medicine, or internal medicine. The time point to determine the etiology of ALC was at the time of discharge from the ER. A total of 315,526 patients who visited ER due to ALC were reviewed and found 7988 eligible patients, of which 4298 (53.8%) were male and 5282 (66.1%) were older than 60. The overall mortality was 13.5%. Except undetermined, the 9 etiologies (n = 7552) were categorized into extra- (n = 4768, 63.1%) or intracranial etiology (n = 2784, 36.9%). The most common etiology of ALC in the ER was metabolic cause (n = 1972, 24.7%), followed by systemic infection (n = 1378, 17.3%). The majority of ALC in the ER was derived from extracranial etiology. ALC in the ER is a neurological manifestation of diverse etiologies; not all can be confirmed in the ER. Not only neurological but also critical systemic illnesses should be considered to assess the protean manifestations of ALC in the ER.

Abstract
Altered levels of consciousness (ALCs) is a challenging issue; however, data describing its etiology and frequency are lacking. This study aimed to clarify and classify the etiologies of ALCs in the emergency room (ER) and to evaluate their destinations and the form of discharge. This retrospective study included patients with an ALC who visited the ER of a university hospital between January 2018 and December 2020. The cause and classification of the ALCs were carefully determined by a consortium of board-certified faculty members in emergency medicine, internal medicine, and neurology. The reference point for determining the etiology of ALC was discharge from the ER. In total, 2028 patients with ALCs were investigated. More than half (1037, 51.1%) visited the ER between 9:00 and 18:00. The most common etiology was systemic infection (581, 28.6%), followed by metabolic causes (455, 22.4%), and stroke (271, 13.4%). The two leading etiologies were extracranial and had a majority of the cases (1036, 51.5%). The overall mortality rate was 17.2%. This study provides fundamental information on ALC in the ER. Although intracranial etiologies have been foregrounded, this study demonstrated that extracranial etiologies are the main cause of ALC in the ER.

Abstract
Background: Although altered mental status is a term commonly used for older patients, the limits of the definition are unclear. Objectives: We aimed to determine the predictive factors of altered mental status and to standardize this broad-spectrum definition. Methods: The level and content of consciousness were assessed both in the basal status and in the emergency department presentation status of patients who were aged 65 years and above. The Richmond Agitation–Sedation Scale (RASS) for level and five features for content of consciousness were used to determine the actual change in consciousness. Results: Among 1250 patients, the rate of true altered mental status was 7.7% ( n = 96), transient altered mental status was 3.5% ( n = 44), and non-altered mental status was 88.8% ( n = 1110). The 1- and 3-month mortality rates were higher for patients with true altered mental status (32.3% and 40.6%, respectively) than for other patients (3.3% and 8.4%, respectively; p < .001). The following criteria predicted true altered mental status with a high specificity: a change in RASS score ⩾2 points, newly disorganized thoughts, a perception disorder, inattention and disorientation, and an inability to communicate. Conclusion: True altered mental status criteria can be used to determine alterations in consciousness that lead to high mortality, and they can also be used as a common language for current and further investigations.

Abstract
OBJECTIVES Altered mental status (AMS) is a challenging diagnosis in older patients and has a large range of etiologies. The aim of this study was to investigate the nature of such etiologies for physicians to be better aware of AMS backgrounds and hence improve outcomes and mortality rates. METHODS This prospective observational study was conducted at 4 emergency departments. Patients 65 years and older who presented to the emergency department with acute AMS (≤1 week), with symptoms ranging from comas and combativeness, were eligible for inclusion in this study. The outcomes, etiologies, Richmond Agitation and Sedation Scale scores, and the presence of delirium were recorded. RESULTS Among 822 older patients with AMS, infection (39.5%) and neurological diseases (36.5%) were the most common etiologies. The hospital admission and mortality rates were 73.7% (n = 606) and 24.7% (n = 203), respectively. The mortality rate rose if AMS persisted for more than 3 days. Delirium was observed in 55.7% of the patients; these individuals had higher durations of AMS than those without delirium (median, 24 hours; interquartile range, 3-48 hours; median 6 hours, interquartile range, 3-48 hours, respectively; P = .010). Notably, delirium was observed in more than two-thirds of neurological patients. CONCLUSIONS The most common causes of AMS were infection and neurological diseases. Delirium was associated with AMS in nearly half the patients. Moreover, the rates of hospitalization and mortality remained high.

Abstract
BACKGROUND Altered mental status (AMS) is a very common emergency case, but the exact etiology of many AMS patients is unknown. Patients often manifest vague symptoms, thus, AMS diagnosis and treatment are highly challenging for emergency physicians. The aim of this study is to provide a framework for the assessment of AMS patients. This assessment should allow providers to better understand the etiology of mental status changes and therefore improve diagnostic skills and management. METHODS This is a prospective cohort observational study. We recruited all adult patients with undifferentiated AMS at a single center tertiary care academic emergency department over 24 months (June 2009 to June 2011). Demographic characteristics, clinical manifestations, assessment approaches, causative factors, emergency treatments and outcomes were collected prospectively. RESULTS In 1934 patients with AMS recruited, accounting for 0.93% of all emergency department (ED) patients, 1 026 (53.1%) were male, and 908 (46.9%) female. Their average age was 51.95±15.71 years. Etiologic factors were neurological (n=641; 35.0%), pharmacological and toxicological (n=421; 23.0%), systemic and organic (n=266; 14.5%), infectious (n=167; 9.1%), endocrine/metabolic (n=145; 7.9%), psychiatric (n=71; 3.9%), traumatic (n=38; 2.1%), and gynecologic and obstetric (n=35; 1.9%). Total mortality rate was 8.1% (n=156). The death rate was higher in elderly patients (≥60) than in younger patients (10.8% vs. 6.9%, P=0.003). CONCLUSIONS Patients with AMS pose a challenge for ED physicians. The most frequently encountered diagnostic categories causing AMS were primary CNS disorders, intoxication, organ system dysfunction, and endocrine/metabolic diseases. AMS has a high fatality rate in the ED. AMS is an important warning signal for ED patients because of its potentially fatal and reversible effects. Prompt evaluation and treatment are essential to decreasing morbidity and mortality associated with AMS.

Abstract
Aims Patients with altered mental status (AMS) present commonly to the Emergency Department (ED). The aim of this prospective study is to identify the various clinical features of this diverse group of patients and trace their outcomes. This will allow clinicians to be aware of the natural history of the symptom complex and the difficulties in managing them. Methods In this prospective observational study, we recruited patients aged 18 and above diagnosed with AMS at Tan Tock Seng Hospital ED from December 2006 to October 2007. This is an urban ED. Demographic, clinical, radiology, laboratory data, final diagnosis and length of stay were collected from their entry into the ED till discharge or demise using the ED’s and inpatient electronic records. Results From December 2006 to October 2007, 967 patients with a mean age of 66.5 years diagnosed with AMS were recruited into our study. The total number of CT scans done during the study period was 674, of which 246 (37%) were abnormal and 428 (63%) were normal. The mean hospital length of stay was 11.6 days. Patients with abnormal CT results stayed longer than those whose results were normal (median of 9 days versus median of 6 days). The three most common causes of AMS in our study population were of neurological (34.4%), infectious (18.3%) and metabolic (12%) aetiologies. Overall, 106 (11%) patients died during hospitalisation; 36 (33.9%) and 39 (36.8%) deaths were attributed to ischaemic stroke and haemorrhagic stroke, respectively. Conclusions AMS remains a symptom complex that carries a significant length of hospital stay and mortality. The most common causes of AMS are those that require timely intervention and are highly treatable. This study will provide insight into proper allocation of resources to manage this group of patients, from triaging to investigations and treatment at the ED and inpatient levels.
