Detecting Cognitive Impairment and Dementia in the Emergency Department: A Scoping Review

      Abstract

      Objectives

      To identify research and practice gaps to establish future research priorities to advance the detection of cognitive impairment and dementia in the emergency department (ED).

      Design

      Literature review and consensus-based rankings by a transdisciplinary, stakeholder task force of experts, persons living with dementia, and care partners.

      Setting and Participants

      Scoping reviews focused on adult ED patients.

      Methods

      Two systematic scoping reviews of 7 medical research databases focusing on best tools and approaches for detecting cognitive impairment and dementia in the ED in terms of (1) most accurate and (2) most pragmatic to implement. The results were screened, reviewed, and abstracted for relevant information and presented at the stakeholder consensus conference for discussion and ranked prioritization.

      Results

      We identified a total of 1464 publications and included 45 to review for accurate tools and approaches for detecting cognitive impairment and dementia. Twenty-seven different assessments and instruments have been studied in the ED setting to evaluate cognitive impairment and dementia, with many focusing on sensitivity and specificity of instruments to screen for cognitive impairment. For pragmatic tools, we identified a total of 2166 publications and included 66 in the review. Most extensively studied tools included the Ottawa 3DY and Six-Item Screener (SIS). The SIS was the shortest to administer (1 minute). Instruments with the highest negative predictive value were the SIS (vs MMSE) and the 4 A's Test (vs expert diagnosis). The GEAR 2.0 Advancing Dementia Care Consensus conference ranked research priorities that included the need for more approaches to recognize more effectively and efficiently persons who may be at risk for cognitive impairment and dementia, while balancing the importance of equitable screening, purpose, and consequences of differentiating various forms of cognitive impairment.

      Conclusions and Implications

      The scoping review and consensus process identified gaps in clinical care that should be prioritized for research efforts to detect cognitive impairment and dementia in the ED setting. These gaps will be addressed as future GEAR 2.0 research funding priorities.

      The prevalence and documentation of impaired mental status in elderly emergency department patients.
      The Geriatric Emergency care Applied Research 2.0 Network–Advancing Dementia Care (GEAR 2.0 ADC), a National Institute of Aging (NIA)–funded effort, was created to support research to fill these gaps in emergency care for PLWD and their care partners. Detection of those in the ED with cognitive impairment or dementia was prioritized as one of the 4 critical domains for further investigation by stakeholders and task force members of the GEAR 2.0 Network. GEAR identifies research gaps and proposes research priorities for the detection of cognitive impairment and dementia in the ED with a scoping review process and a stakeholder consensus approach. The goal is to support research focused on these priorities, thus generating evidence to inform and advance better patient care. This article details the scoping review process, its results, and the research priorities of the subsequent GEAR 2.0 ADC Consensus Conference.

      Methods

      The GEAR 2.0 ADC task force was recruited from a pool of cognitive impairment, dementia, geriatrics, and emergency medicine experts identified through prior collaborations, geriatric emergency medicine focus groups, and partner organizations. The workgroup included ED-based and non-ED-based clinicians, individuals living with dementia, care partners, and advocacy organizations. GEAR 2.0 ADC members were selected based on membership in national geriatric emergency medicine interest groups and through relevant publications in the GEAR 2.0 ADC domains. The task force members were assigned to one of 4 workgroups representing research and practice priority domains: ED Care Practices, ED Care Transitions, Communication and Decision Making, and Detection and Identification (Detection). A list of task force members can be found in the Acknowledgments section.
      The GEAR 2.0 Detection workgroup consisted of 20 individuals: 6 emergency medicine physicians, 2 neuropsychologists, 2 geriatricians, 2 staff researchers, 1 geriatric psychiatrist, 1 preventive medicine physician, 1 librarian, 1 social worker, 1 nurse practitioner, 1 biostatistician, 1 PLWD, and 1 care partner. The workgroup, over the course of 6 months, convened videoconference meetings to discuss the scoping review aims, propose the research questions, review the search criteria, and examine the scoping review results, and abstraction of final papers.

      PICO Questions
      The GEAR 2.0 ADC Detection workgroup generated the following PICO questions:

      Detection PICO-1:

      How can the ED best identify cognitive impairment? (Best in terms of sensitivity, reliability, practicality, ease, and speed of completion, etc.) Are there differences by race or ethnicity?
      Population: All ED patients (no children, no studies that excluded patients older than 65).
      Intervention: ANY assessment available during the ED visit to identify cognitive impairment, cognitive frailty, or confusion.
      Comparison: Gold/Reference standard assessments.
      Outcomes: Measures of diagnostic accuracy including sensitivity, specificity, likelihood ratios, etc. against gold standards.

      Detection PICO-2:

      Are there pragmatic cognitive impairment screening tools that can identify patients at risk of dementia? (Pragmatic in terms of ease of use, training, quickness to complete, etc.)
      Population: All ED patients (no children, no studies that excluded patients older than 65).
      Intervention: ANY assessment available during the ED visit to identify cognitive impairment, cognitive frailty, or confusion.
      Comparison: Gold/Reference standard assessments.
      Outcomes: Time on task for assessment, clinician acceptability of assessment, training time for assessment, completion rates of assessment, patient harms from assessment.

      Search Strategy

      Published literature was searched using strategies developed by the 4 participating medical librarians. They established common search terms and key words across the workgroups. The medical librarian (AB) used the Detection workgroup PICO questions and their corresponding exemplar articles to guide, refine, and develop search strings specific to the domain of cognitive impairment. PICO 1 focused on measures of diagnostic accuracy including sensitivity and specificity, models, and reproducibility of results to detect and assess cognitive impairment and dementias. PICO 2 focused on the approach, practicality, and usability of the assessment as part of emergency clinical care. We searched Ovid Medline, Embase, CINAHL, CENTRAL, APA PsycINFO, Web of Science, and PubMed Central (see Supplementary Material 1) We deduplicated in 2 sequential automated steps: first, a deduplication system developed at the Cushing/Whitney Medical Library at Yale University was used. The remaining articles were then uploaded to Covidence (Covidence systematic review software, Veritas Health Innovation, Melbourne, Australia), a web-based article review screening and extraction tool for scoping reviews. One additional deduplication step was performed through Covidence. Full search strategies are provided in the supplement.

      Study Selection and Abstraction

      The scoping review literature search was completed in May 2021. Two independent reviewers (U.H., A.N.) screened titles and abstracts for inclusion and exclusion criteria. Inclusion criteria for PICO 1 and PICO 2 were studies of assessments or tools that assessed for cognitive function focusing on dementia and occurred in the ED setting. Exclusion criteria for both PICO questions were studies that took place in children, did not include patients greater than 65 years in age, exclusively focused on delirium, or exclusively focused on traumatic brain injury. Articles that did not explicitly mention patients with cognitive impairment were retained in the full-text review if they met all other inclusion criteria. Additionally, systematic reviews pertinent to our objectives were kept and their reference lists were examined for relevance to the PICOs. Studies were retained if they met inclusion criteria and were not already identified in the initial search. The full texts of the articles that met these criteria were then reviewed. In cases of disagreement between the reviewers adjudication occurred via consensus between the 2 reviewers, or by a third workgroup member (C.C.).
      Three authors (J.D., W.H., A.N.) abstracted the following data from the final articles based on a template that included standardized elements across the 4 workgroups such as study setting, participant demographics, race or ethnicity, and inclusion or exclusion criteria, among other information.
      The PICO 1 abstractions included the screening instrument or tool studied, the gold standard used for dementia or cognitive impairment, and measures of accuracy, reliability, sensitivity, specificity, likelihood ratios, correlation coefficients, etc. For PICO 2, objective measures of feasibility, pragmatic nature, timing, or efficiency of a tool were abstracted. If no objective measures were reported, then authors' remarks on a tool's feasibility were abstracted. These included ease of use, speed, setting, integration into routine care, the outcome effect and size, feasibility, acceptability, safety, and other measures of success or failure of the interventions.

      Research and Practice Gap Assessment

      The results of the scoping reviews, including the abstraction tables and publications, were discussed by the Detection workgroup. The group also discussed how to present the available research and practice gaps to the GEAR 2.0 ADC Consensus Conference.
      The scoping review results were presented at the GEAR 2.0 ADC Consensus Conference meeting from September 10 to 11, 2021. The goal of the meeting was to have stakeholders analyze the current evidence and identify the research and practice gaps for future research. Members discussed and voted on the research priorities in the detection of cognitive impairment in the ED. To effectively discuss the topic, participants were split into 4 groups. The groups then reconvened and discussed the perceived research and practice gaps needing attention. This discussion was then synthesized by the Detection workgroup to form the final research priorities. All Consensus Conference attendees voted to prioritize the research and practice gaps to provide guidance for future GEAR 2.0 pilot funding opportunities. Those absent from the conference were asked to vote asynchronously, for 100% participation by all 4 workgroups and Health Equity Advisory Board members.

      Results

      Abstraction Process

      We identified 1464 citations for PICO 1; we removed 1271 citations as they did not meet inclusion criteria. The interrater reliability between both screeners was modest (κ = 0.67). Ninety-three underwent full-text review, from which an additional 50 were excluded (19 had no measures of diagnostic accuracy, 15 were not in the ED, 5 did not detect dementia, 5 were duplicates, 3 were abstracts of existing full papers, 1 focused only on traumatic brain injury, 1 focused only on delirium, 1 was a letter to the editor), leaving a total of 43 manuscripts for PICO 1 abstractions. Two additional manuscripts were identified from references listed in the abstracted manuscripts bringing the total number of manuscripts to 45. See Supplementary Figure 1, PRISMA-ScR flow diagram PICO 1.
      We identified 2166 citations for PICO 2; we removed 2030 as they did not meet inclusion criteria. The interrater reliability between both screeners was low (κ = 0.37). One hundred thirty-six underwent full-text review, from which an additional 70 were excluded (33 had no measure or mention of feasibility or pragmatic nature, 25 were not in the ED, 5 did not detect dementia, 3 were abstracts of full-text papers, 3 were duplicates, 1 was not available in English), leaving 66 papers for PICO 2 abstractions. During the abstraction process, 1 manuscript was removed as it was a duplicate and 1 additional manuscript was identified by reference review. See Supplementary Figure 2, PRISMA-ScR flow diagram PICO 2.
      There were 21 articles that were included in both PICO 1 and PICO 2 literature abstractions. See supplement for full abstraction tables (Supplementary Tables 1 and 2).

      Abstraction Results

      PICO 1

      Of the 45 manuscripts, 9 only had abstracts with 3 from the same study, and 5 were review papers or editorials. Patient race or ethnicity or language spoken were reported 33% and 31% of the time in abstracted manuscripts, respectively. All those reported were English-speaking except for 2 studies that enrolled French-speaking patients. No manuscript captured sexual orientation or religious faith of the participants. Age for inclusion varied, ranging from >18 years to >75 years. The majority of manuscripts included people aged ≥65 years. The number of studies and age criteria were as follows: ≥18 years (1), ≥45 years (1), ≥55 years (1), ≥60 years (1), ≥65 years (24), ≥70 years (4), and ≥75 years (7).
      Twenty-seven different assessments or instruments were evaluated or mentioned in the 45 abstracted manuscripts for PICO 1 (Table 1). The Mini-Mental Status Exam (MMSE) was the most commonly used measure as the gold standard in 23 of these 45 studies. Other measures that were used were the modified Telephone Interview for Cognitive Status–modified (TICS-m); the Montreal Cognitive Assessment (MoCA); the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE); previously documented history; patient or kin report; the Orientation, Memory, Concentration Test (OMCT); the Eight-item Interview to Differentiate Aging and Dementia (AD8); the Short Blessed Test (SBT); Bergman-Paris Question; Brief Risk Identification for Geriatric Health Tool (BRIGHT); and the ED Mini-Cog in declining order of use.

      Of the 66 manuscripts abstracted, 5 were not in English but had English abstracts, 4 reported on race or ethnicity, and 5 reported on language. None reported sexual orientation or religious faith, and 20 reported measures of feasibility.
      Studies evaluating feasibility focused on (1) the length of time needed to administer the assessments and (2) barriers and acceptability of screens. Time was the most commonly studied measure of feasibility. The time needed to complete an assessment was a concern of clinicians, with an ideal time of <5 minutes reported in the survey by Zun et al

      Discussion

      Over the last 2 decades, there have been multiple studies evaluating ED detection of cognitive impairment specifically focused on dementia. Our scoping review identified more than 45 manuscripts addressing accuracy of detection of cognitive impairment or dementia, 66 addressing pragmatic and practical ways for this detection, and 21 manuscripts overlapping in both. Most commonly studied instruments found to have high sensitivity and negative predictive value included the SIS,

      Although these limited data support their use to screen for dementia in the ED, there was consensus that the findings were heterogeneous and more evidence was needed to inform best practices. The GEAR 2.0 task force determined that although it is widely accepted that detection of cognitive impairment in the ED is beneficial and critical to providing good care, to accomplish this efficiently and effectively remains an undermet need. Many of these tools have existed for decades, but continue not to be implemented into practice. Research is needed to address concerns about feasibility, demonstrate their applicability, and find ways to increase their integration into clinical care. Determining the best approach in the ED for screening cognitive impairment was the top research priority from this transdisciplinary group of stakeholders that also included PLWD and their care partners. The approaches should encompass pragmatic screening processes, interventions that include referral for subsequent evaluation, and even use of patient and population risk factors or electronic health record data to improve detection of cognitive impairment and dementia in the ED setting. Such evidence could change and improve practice.
      The need for more research to develop accurate and feasible tools to identify cognitive impairment in the absence of delirium or known dementia was the next priority focus ranked by the GEAR 2.0 Consensus Conference. In the ED setting, when patients often present with changes in cognition, it is important to determine if the impairment is new and originates from a treatable medical condition such as delirium, or from a slower decline in cognition in the setting of chronic cognitive impairment (dementia) not previously recognized. Delirium is a medical emergency and requires prompt assessment and treatment.

      Delirium in older persons: Advances in diagnosis and treatment.
      Dementia is a risk factor for delirium, and not recognizing it can impact clinical decision making, patient care transitions, and safety. Developing instruments to differentiate the two are critical for the ED setting. The importance of understanding what information is needed to differentiate delirium vs undiagnosed cognitive impairment vs known dementia and other mental health etiologies was thus another important research priority ranked by the GEAR 2.0 task force.
      The next Detection research priority ranked by the Consensus Conference focused on understanding the value and potential unintended consequences of screening for cognitive impairment in the ED. Priorities expressed by PLWD on the task force emphasized the importance of clear communication of purpose, potential risks, benefits, and value of cognitive screening. Efforts in the ED should be made to ensure the patient and care partners have an understanding of the screening results and potential follow-up steps.

      Attitudes and preferences towards screening for dementia: A systematic review of the literature.
      There may be misunderstandings around both the reasons for a screen and the implications of test results. Therefore, clear communication should be made that the screening does not constitute diagnosis, but rather may lead to additional evaluation and management after the ED visit by appropriate clinicians. Moreover, consideration to whether a care partner is to be informed and involved in the decision making is also important. The individual being screened may have preferences about whether they would want to know if cognitive impairment is present and if the results should be communicated to care partners and to whom.

      Another research priority ranked by the task force was how to account for culture, language, the ED environment, and communities of the population served when screening for cognitive impairment in the ED. Although the scoping review searches identified 101 articles, most of these articles focused on the detection of dementia or cognitive impairment in limited languages, most in English, some in French, and 1 in Spanish. Some studies even excluded patients if they were non-English speaking. The GEAR 2.0 Consensus Conference emphasized the importance of cognitive impairment detection to define the characteristics of patients that present to the ED, including aspects like language, ethnicity, and social determinants of health that may predispose patients to inequitable differences in health and medical care.
      Finally, the GEAR 2.0 Consensus Conference emphasized that the ED's role is not to assign a definitive diagnosis of dementia. It is important to acknowledge the US Preventative Services Task Force statement that there is no trial evidence to support screening older adults for cognitive impairment. They also state that early diagnosis of cognitive impairment does not improve patient, caregiver, family, clinician decision making, or other important outcomes, nor does it cause harm.

      For the GEAR 2.0 Consensus Conference, however, the presence of an older person in the ED with signs, symptoms, or complaints of cognitive change does, in fact, warrant evaluation to ensure appropriate care in the ED and referral at discharge. A review of practice guidelines for dementia detection indicates that cognitive evaluation should occur “when a caregiver” such as a family member, friend, or other informant describes cognitive decline.

      Systematic review of recent dementia practice guidelines.
      The 3 most common aspects of the evaluation that are the minimum requirement for diagnosis are (1) cognitive assessment with a standardized tool, (2) evaluation of comorbid conditions with medication review and laboratory tests, and (3) a history and physical examination. All steps are required, although they may be difficult to achieve in the ED setting.

      Conclusion and Implications

      We report the results of 2 systematic scoping reviews evaluating diagnostic accuracy and feasibility to detect cognitive impairment and dementia in the ED setting. The GEAR 2.0 Advancing Dementia Care task force, using these results, developed consensus research priorities practice gaps to advance the detection of cognitive impairment and dementia in the ED setting. They include the need for more effective and efficient approaches to recognize persons at risk for cognitive impairment and dementia. These approaches should balance the importance of equitable screening and the goal and the consequences identifying cognitive impairment. These research priorities will be the basis of future GEAR 2.0 research funding opportunities.

      Patients were more likely to screen positive for cognitive impairment using the SIS if they were 85 y or older (RR 1.63, P < .001), Black (RR 1.85, P < .001), and male (RR 1.42, P < .001). Interestingly, only age was significantly associated with screening positive for cognitive impairment in the ED using the CLOX1 (75-84 y: RR 1.35, P < .001; ≥85 y: RR 1.69, P < .001)
      Carpenter∗, 2008Clinicians should select one population-appropriate primary screening tool and consider others for specific situations. For example, if one has very little time available, the Clock Drawing Test may be the most useful screening tool, whereas the Hopkins Verbal Learning Test may be superior in mildly impaired or highly educated patients. The MMSE has been evaluated most extensively, but current copyright restrictions limit its use, and diagnostic inaccuracy is a problem in relationship to educational levels.

      Cohort study or case-control study

      Study population consisted of patients with a mean or median age ≥65 y, visiting an ED.

      The target condition was cognitive impairment irrespective of the etiology. The diagnosis was based on the DSM criteria (version III, IV, IV-R, V) made by a specialist in geriatric care. CAM and MMSE were accepted as a substitute gold standard because of their wide use in clinical practice.

      The index test was an instrument to assess cognition in the ED.

Other observations in the ED included suspicion or nervousness about the Cognigram. Adults were not comfortable with the idea of cognitive testing, even when assured anonymity.

      Koita 2010N/AN/AN/AArticle discusses the process for conducting a mental status examination on a patient in the ED. It mentions SIS, clock drawing, Mini-Cog, Memory Impairment Screen, Brief Alzheimer Screen, 7-min screen, and MMSE as tests for neurologic mental status examinationsNoN/AThe 7-10 min needed to perform the MMSE and the copyright laws pose further barriers for easy ED use. The 1996 US Preventative Services Task Force literature review found the MMSE, Short Test of Mental Status, the Blessed Orientation Memory Concentration Test, and Functional Activities Questionnaire were all equivalent as a screening tool for detecting dementia. These cognitive tests have not been studied in the ED setting, however, and do not have a defined role in the ED at this time. Wilber and colleagues performed a study in the ED setting comparing the MMSE, SIS, and Mini-Cog. The Mini-Cog consists of 3-item recall and clock drawing; SIS consists of 3-item recall and 3-item temporal orientation (ie, day of week, month, and year). When using a cutoff score of ≤4 in SIS, the SIS proved to be better than the Mini-Cog. In comparison to the MMSE, the SIS had a sensitivity and specificity of 94% and 86%, respectively, whereas the Mini-Cog had a sensitivity and specificity of 75% and 85%, respectively. Initially, Callahan and colleagues found SIS to perform as well as MMSE, but repeat studies have shown that SIS only had a sensitivity of 63% and specificity of 81%. Cognitive assessment in the ED continues to be an area in need of research.
      Krupp 2018, Germany; acute geriatric departmentN = 165Patients in an acute geriatric department performed the SIS (4 times), the MMSE (2 times), CDT according to Shulman (2 times), the Regensburg verbal fluency test (2 times), and the Montgomery-Åsberg depression rating scale within a period of 16 d. The overall judgment of a physician blinded to the test results served as the reference standard.SIS, MMSE, clock drawing, Regensburg verbal fluency, Montgomery-Asberg depression scaleNoThe SIS closely correlated with the medical judgment (−0.729). The SIS is a valid, reliable short cognitive test. Using a threshold of 5 points, the SIS detects cognitive deficits relevant to daily living with a higher sensitivity than the MMSE with a threshold of 25. The brevity and simple application of the SIS also enable its application outside geriatric wards.

Asked of patient's close relative “Would you be comfortable leaving your family member home alone for three months if you had to go on a trip to Paris and no other family member or close friend was available?” The purpose of the study was help assess if further geriatric assessments were needed of the patient.YesThe BPQ had good sensitivity but a low specificity for detecting the 3 geriatric syndromes, cognitive impairment, functional impairment, and frailty. The BPQ could be used to flag patients who would benefit from further screening.
      Laguna 1997, EDN = 536; age ≥ 60 yPatients aged ≥60 y seen in EDNo exclusion criteriaTo check the reliability of the usual medical assessment to detect the cognitive deterioration in older adults attended at HED, compared with that performed systematically by means of an evaluation test of cognitive functionsNoCognitive deterioration was not detected in 111 patients (31.5%); it was mild in 147 (41.8%), moderate in 71 (20.2%), and severe in 23 (6.5%). In patients with moderate-severe deterioration according to the OMCT, such a deterioration was detected by the usual medical evaluation in 7% of cases. The mean time in completing the test was 2.6 ± 0.9 min. An age ≥80 y was associated with an increased relative risk for detecting moderate-severe cognitive deterioration (1.98; 95% CI, 1.42-2.78; P < .001), whereas the discharge diagnosis of respiratory disease was associated with a decrease of the relative risk (0.41, 95% CI 0.19-0.89; P < .05)
      Lanata 2014, Rhode Island HospitalN = 23 resident physiciansFor chart review: admitted to medicine or neurology wardAuthors reviewed charts for 100 adult patients admitted to medicine and neurology wards; 23 resident physicians were questioned about their use of cognitive screening tools.NoAuthors found 67% and 63% of patients evaluated by attendings in the emergency and medicine departments, respectively, did not receive any form of cognitive testing. In addition, 62% of patients evaluated by neurology attendings received cognitive testing. No physician preformed hierarchical, systematic mental status examinations. The most common reason cited by resident physicians for not using standardized cognitive screening tools was lack of time.

      Maxwell 2013, 2 acute care community hospitalsN = 80; 78.7 y mean; 44%; 27Patients aged ≥65 y visiting ED with a primary injuryThe Mini-Cog or Informant Questionnaire on Cognitive Decline in the Elderly (IQCDE) and Vulnerable Elder Survey (VES-13) were administered to patients or surrogates.Cognitive impairment was present in 36 (44%) of patients (abnormal Mini-Cog: 22%; IQCDE > 3.44: 22%). Injured older adults had higher cognitive and preinjury functional impairment than has been reported in other older populations. A combination of brief screening instruments for use with hospitalized injured older adults or surrogates is useful for risk assessment and clinical management.

      Morley 2013, Ireland; hospitalN = 35 HIV clinic and ED cliniciansClinician in HIV clinic or EDSurveyed clinicians about cognitive screening tools used and factors limiting cognitive assessments in the clinical settingNoParticipants were asked if an assessment of Orientation in Person, Place and Time (OPPT) was an adequate screening tool for detecting HIV dementias. They were presented with the names of other cognitive screening tools and were asked which they had used previously with HIV-positive patients. MMSE, MoCA screen, the Abbreviated Mental Test (AMT) score, the International HIV Dementia Scale (HIVDS), and the Brief Neurocognitive Screen (BNCS). Thirty-four percent (n = 12) of respondents felt that OPPT was a sufficient screening tool for cognitive assessment. Respondents found lack of time, exposed environment, and lack of privacy the most limiting factors when performing cognitive assessment on patients who present acutely to the ED.
      Myrstad 2018, Norway; ED; October 2017–May 2018N = 111; age ≥65 y, 81 y meanPatient seen in ED with suspect infection and admittedED nurses screened patients with qSOFA and 4AT (rapid screening of alertness, cognition, attention and fluctuation of symptoms). Time spent on 4AT was recordedqSOFA and 4AT.YesMedian time spent on the assessment with 4AT was 2 min (mean 2.6 min). Among 39 patients with a qSOFA point given for altered mental state, 4AT revealed signs of cognitive impairment in 37 (95%). 4AT revealed signs of cognitive impairment in 26 of 72 patients (36%) where qSOFA did not reveal an altered mental state. 4AT is a rapid assessment of cognitive impairment feasible for use in the ER. 4AT improved the assessment of cognitive impairment in patients aged ≥65 y with suspected infection.
      Ngian 2008, Australia; teaching hospital; January 2004-April 2006N = 103; age ≥70 y; 83 y mean (±6.5)Patient meeting ASET referral criteria: age ≥70 y, and 2 of the following 5 criteria required to trigger referral: (1) multiple health problems or >3 regular medications, (2) history of falls or fall-related injury, (3) >3 presentations to ED in the last 6 mo, (4) problems with memory, or (5) patient or caregiver reports recent functional or behavioral change.N/RStudy objectives were to review discordant cases (using EMR)— older adult patients deemed for discharge by ED but subsequently admitted following ASET review. These cases were examined with regard to clinical outcomes. ASET contribution was also reviewed with respect to assessment of cognitive, functional, and mobility status.NoAssessment of older adult patients by ASET yielded additional information on functional, mobility and cognitive issues that were overlooked by ED.
      O'Sullivan 2016∗This is a review article citing the use of the 6-CIT screen in primary care, outpatient care, and EDsYesThe 6-CIT has been shown to be a fast, feasible method for screening for cognitive impairment in older adults in the ED, with a mean completion time of 1.9 min. In a US-based study involving 163 ED patients (mean age 78 y), the 6-CIT demonstrated excellent sensitivity at 95% and specificity at 65% (AUC = 0.930) for cognitive dysfunction based on MMSE scores of ≤23. However, this result was achieved using a lower 6-CIT cutoff of 4/5, and there was no randomization between criterion standard testing and screening. Another US research group used the 6-CIT to screen for cognitive impairment in 271 older patients in an urban teaching hospital ED. The psychometric properties of the instrument were not analyzed; however, the researchers claimed to have discovered 46 from a total of 55 cases of cognitive impairment, where no previous history of cognitive impairment existed.

      Salen 2009, US; ED; N/RN = 100; age ≥65 y; 9%Age ≥65 y, English-speaking community-dwelling people seen in a community hospital EDPresenting for altered mentation, evidence of critical illness as reflected by abnormal vital signs (systolic blood pressure 100 mm Hg, pulse 100 beats/min, temperature 37.8 °C (100 °F), pulse-oximetry 95% on room air), lived in a nursing home or in an assisted-living situation, history of dementia or delirium, or if they refused to participate.Primary objective of this study was to assess the prevalence of cognitive impairment as reflected by an inability to correctly perform a CDT in older adult patients presenting to the ED for reasons other than altered mental status. Also sought to assess whether an ED cognitive impairment screening program as reflected by an abnormal CDT prompted further evaluation of mental functioning by primary care physicians.CDTYesThe CDT seems to be a feasible means for identifying older adult ED patients at risk for cognitive disorders. Routine cognitive screening of older adults with the CDT seems to be well accepted by patients and families, but the sporadic follow-up by PCPs suggests a role for more aggressive ED interventions to delineate the causes of abnormal cognitive screening examinations.

ED physicians were trained in its use during the control period, June-October 2012. October 2012–June 2013 was the screening period.The tool met the following prerequisites: (1) EGS is multidimensional and covers relevant domains of geriatric problems; (2) EGS uses validated instruments; and (3) EGS must be feasible in an ED. The domains were relevant for older ED patients: cognition, falls, mobility, and ADLYesEGS took <5 min to perform in most (85.8%) cases. Of the 70 invited ED physicians, 41 (64.1%) returned the questionnaire that asked about their experience with the EGS. Most responders agreed or partially agreed that EGS domains are suited to detect geriatric problems: 73.0% agreed or partially agreed for cognition; 77.8%, for falls; 75.0%, for mobility; and 72.2%, for ADL

The 4AT had an AUC of 0.90. The 4AT had specificity of 95% (95% CI 92-97) and sensitivity of 76% (95% CI 61-87). The CAM had specificity of 100% (95% CI 98-100) and sensitivity of 40% (95% CI 26-57). Patients with positive 4AT had longer lengths of stay (median 5 d, IQR 2.0-14.0) than negative 4AT (median 2 d, IQR 1.0-6.0) and higher mortality. Cognitive test items of the 4AT were highly specific (AMT4 score 2:97% 94%-98%); attention score of 2: 98% (96%-99%); but showed lower sensitivity (AMT4 score 2: 47% 32%-62%); attention score of 2: 62% (36%-83%) in detecting existing dementia. Conclusions: The 4AT is a rapid delirium assessment instrument that is feasible in routine care, including with patients with dementia, which has good diagnostic accuracy for delirium for acutely unwell older patients
      Singh 2013The objective was to review published evidence on the Rapid Assessment Interface and Discharge (RAID) service model, examining the strengths and weaknesses of the service design, outcome, and effectiveness. The RAID service has shown quality improvement in the care of older people by reducing their length of stay, avoiding their admission to acute hospital beds, and discharging them in increased numbers back to their original place of residence, rather than an institution or care home. In addition, the RAID model has been shown to reduce the readmission rate after discharge by 65% in comparison with a pre-RAID group. The psychiatric liaison service can support the management of behavioral and psychological symptoms in patients with dementia; an audit of antipsychotic prescriptions for people with dementia has showed a 52% reduction in antipsychotic prescriptions for people with dementia between 2008 and 2011. The RAID service could have contributed to reduced antipsychotic prescriptions, but this was not actually studied as part of the evaluation.NoThe RAID service has shown quality improvement in the care of older people by reducing their length of stay, avoiding their admission to acute hospital beds, and discharging them in increased numbers back to their original place of residence, rather than an institution or care home.

Correlation of QCS and MMSE scores was fair, with Pearson r = 0.61 (95% CI 0.56-0.66). Conclusions: The QCS can be administered more quickly than the MMSE and is easier to administer in the ED
      Sunkara 2019, NY; ED; March 1–July 1, 2018N = 418, age ≥ 75 y, 41.15% screened positive, 80ED patients aged ≥75 y likely to be discharged home, English or Spanish speakingNot reportedMini-Cog (if participant could answer), IQCODE if participant could not respondNoCognitive impairment screening is feasible in the ED and many individuals screen positive. Use of a volunteer workforce may be a feasible interim step to implementing a sustainable program while increasing learners' exposure to positive geriatric care experiences.
      Taylor 2018Older adults aged ≥65 y presenting to the ED

      Administration of a functional and/or cognition assessment instrument whilst the patient is in any part of the ED setting

      •Clinical assessment tools addressing any aspect of functional ability, and/or cognition assessment

      •The study must include an intervention of any description resulting from the outcome of the instrument administration•There must be a measured outcome as a result of the ED-based intervention
      Evaluation of an assessment instrument as the primary outcome

      •Studies that target an intervention of 1 primary diagnostic criterion eg stroke

      •Assessments or interventions not performed in the ED environment

      •Studies only targeting residents of residential aged care facilities (RACFs)
      Scoping review identified 6 measures used for cognitive and delirium screening instruments: AMT, CAM, Blessed Orientation-memory Concentration (BOMC), MMSE, Mini-Cog, Short Portable Status Questionnaire (SPMSQ)Only 2 of the screens, Mini-Cog and MMSE, have been tested for use in ED. Mini-Cog has a drawing section that is a limitation for use in ED. There was no standard time to administer one of the screens. Authors note that doing them early in a patient's visit would help provide needed information that could impact patient disposition.

Previous study showed patients completed the SIS in <1 min (range, 0.5-3.5 min) and Mini-Cog took 1.5 min (0.5-5 min). MMSE takes a median of 5.5 min (range, 3.5-14 min) to complete.
      Wilber 2008∗, Summa Health System's Akron City Hospital, Washington University, Barnes-Jewish Hospital, The Cleveland Clinic; ED; January 2006–January 2007352 participants, age ≥65 y, mean age 77 ± 8; 32%; 0 care partnerAge 65 y; English speakingReceiving medications that may have affected their mental status (narcotics, antiemetics, or benzodiazepines), were critically ill, were unable to con-sent or cooperate with data acquisition, were previously enrolled, or refused to complete the questioningAt Sites 1 and 3, the SIS was administered first, and the MMSE was administered a minimum of 30 min later. At Site 2, the MMSE was administered first, and the SIS was administered a minimum of 30 min later.MMSE, SISNoCompared sensitivity and specificity of SIS to MMSE. Overall, the SIS was 63% sensitive and 81% specific; the NPV was 83% and the PPV was 60% (Table 1). The overall agreement between the 2 tests was 75%. However, we believe that the SIS, testing temporal orientation and recall, is quick and easy for





      EPs to incorporate into their physical examination. It provides an objective measure of cognition, as opposed to the unstructured evaluation of cognition by clinical gestalt (often expressed as A&Ox3).
      Wilding 2016∗, Ontario Canada; ED; January 1, 2010, to August 31, 2010N = 238; age ≥75 y; mean age 81.9 y; 13.4%; 0Patients aged ≥75 y with no history of cognitive impairmentMedically unstable; cognitively impaired; not living in Ottawa; reside in nursing home; non-English or French speaking; hearing/visual impairmentMMSE, O3DY, and AFT. MMSE and O3DY were administered followed by AFTMMSE, O3DY, and AFTNoThe O3DY Scale demonstrated a sensitivity of 93.8% (95% CI 77.8-98.9) and a specificity of 72.8% (95% CI 66.1-78.7). The MMSE and O3DY scale showed agreement in 75.6% of cases. An AFT score <15 demonstrated a sensitivity of 90.6% (95% CI 73.8-97.5) and specificity of 39.3% (95% CI 32.7-46.4). Using a cutoff of <10 for the AFT resulted in a lower sensitivity of 62.5% (95% CI 43.7-78.3) but greater specificity of 78.2% (95% CI 71.8-83.5). The MMSE and the AFT showed agreement in 46.2% and 76.1% of cases with cutoffs of <15 and <10, respectively. The O3DY scale is a feasible screening tool for cognitive impairment in older adult patients presenting to the ED. It is highly practical for use in the time-pressured ED environment, and it does not require paper, pen, or stopwatch. It showed high sensitivity and moderate specificity compared with the MMSE. The AFT did not perform as well, with a much diminished specificity.
      Wilkinson 2018, Canada; EDN = 147; age 70-94 yA “Whack-a-mole” style computer game was created to discern inhibition ability in a geriatric population in the ED. The results of the game were then compared to MMSE, MoCA, and CAM evaluations.The developed game had a correlation to MMSE, MOCA, or CAM, determined as, respectively, −0.558, −0.339, and 0.565 (all with P < .001)NoNoNo

      Zun 1986, mailed surveyN = 170 Board-certified ED physiciansED Board-certified physicianN/RRandom sample of 120 of 1174 American Board of Emergency Medicine–certified emergency physicians and a validation group of 50 Board-certified ED physicians were surveyed by questionnaire.Authors developed a questionnaire to determine the i n d i c a t i o ns, the amount of time necessary to evaluate mental status, the content of the mental status examination (MSE) used, and the ideal characteristics of a short, standardized MSE. The Strub and Black's Composite Mental Status Examination (CMSE) was used as the standard example for answering the questionnaireYes72% of respondents said they take <5 min on the MSENo
      Zun 1988NoNSome physicians view the mental status evaluation as a series of odd maneuvers and questions that appear time-consuming and of questionable clinical significance.

      “Emergency departments are places where physicians have limited time to examine patients. Texts in emergency medicine have advocated the need to perform formal mental status examinations. However, many physicians find the formal mental status examination time-consuming and cumbersome.”

      An extensive test is rarely necessary in the ED; rather a short test of cognitive function, such as the Cognitive Capacity Screening Examination or MMSE, may be more appropriate.

      Working Search Methods

      The review team collaborated with a research librarian (A.L.B.) to develop and execute a comprehensive search of the literature. The search was created in partnership with several librarians and project team members from the larger GEAR 2.0 effort to conduct several scoping reviews on various topics related to dementia care in the field of emergency medicine. This search combined controlled vocabulary and title/abstract terms related to the accuracy and feasibility of dementia screening tools in the emergency department. The search was adapted from a GEAR 2.0 baseline search to fit the needs of the specific project question and translated for the following databases: MEDLINE (Ovid), Cochrane Central Register of Controlled Trials (CENTRAL), Embase (Ovid), CINAHL (Ebsco), APA PsycINFO (Ovid), PubMed Central, and Web of Science (Clarivate). All searches were performed on March 25, 2021. An exclusion filter from McGill University was used to focus on adult patient populations. No other publication type, language, or date filters were applied. Results were downloaded to a citation management software (EndNote) and underwent automated deduplication using a system at the Cushing/Whitney Medical Library at Yale University. Unique records were uploaded to a screening platform (Covidence) for independent review by several project team members using predetermined inclusion and exclusion criteria.
