Frailty assessment in emergency medicine using the Clinical Frailty Scale: a scoping review

BACKGROUND

Frailty is a common condition present in older Emergency Department (ED) patients that is associated with poor health outcomes. The Clinical Frailty Scale (CFS) is a tool that measures frailty on a scale from 1 (very fit) to 9 (terminally ill). The goal of this scoping review was to describe current use of the CFS in emergency medicine and to identify gaps in research.

METHODS

We performed a systemic literature search to identify original research that used the CFS in emergency medicine. Several databases were searched from January 2005 to July 2021. Two independent reviewers completed screening, full text review and data abstraction, with a focus on study characteristics, CFS assessment (evaluators, timing and purpose), study outcomes and statistical methods.

RESULTS

A total of 4818 unique citations were identified; 34 studies were included in the final analysis. Among them, 76% were published after 2018, mainly in Europe or North America (79%). Only two assessed CFS in the pre-hospital setting. The nine-point scale was used in 74% of the studies, and patient consent was required in 69% of them. The main reason to use CFS was as a main exposure (44%), a potential predictor (15%) or an outcome (15%). The most frequently studied outcomes were mortality and hospital admission.

CONCLUSION

The use of CFS in emergency medicine research is drastically increasing. However, the reporting is not optimal and should be more standardized. Studies evaluating the impact of frailty assessment in the ED are needed.

Gender differences in emergency medicine resident assessment: A scoping review

Background

Growing literature within postgraduate medical education demonstrates that female resident physicians experience gender bias throughout their training and future careers. This scoping review aims to describe the current body of literature on gender differences in emergency medicine (EM) resident assessment.

Methods

We conducted a scoping review which adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. We included research involving resident physicians or fellows in EM (population and context), which focused on the impact of gender on assessments (concept). We searched seven databases from the databases' inception to April 4, 2022. Two reviewers independently screened citations, completed full-text review, and abstracted data. A third reviewer resolved any discrepancies.

Results

A total of 667 unique citations were identified; 10 studies were included, and all were conducted within the United States. Four studies reported differences in EM resident assessments attributable to gender within workplace-based assessments (qualitative comments and quantitative scores) by both attending physicians and nonphysicians. Six studies investigating clinical competency committee scores, procedural scores, and simulation-based assessments did not report any significant differences attributable to gender.

Conclusions

This scoping review found that gender bias exists within EM resident assessment most notably at the level of narrative comments typically received via workplace-based assessments. As female EM residents receive higher rates of negative or critical comments and discordant feedback documented on assessment, these findings raise concern about added barriers female EM residents may face while progressing through residency and the impact on their clinical and professional development.

The relationship between empathy and the quality of the educational environment in Canadian emergency medicine residents

Purpose

Empathy and quality of educational environment appear to be inversely correlated with burnout but the relationship between the two is largely unknown. Our primary objective was to examine the relationship between postgraduate educational environment and empathy. Secondary objectives included impact of gender, residency year and on- versus off-service context on levels of empathy and educational environment.

Methods

A modified Dillman approach was used to conduct an email survey of Canadian Royal College Emergency Medicine residents in June 2020. The survey instrument included: demographic data, Toronto Empathy Questionnaire (TEQ) and Scan of Postgraduate Educational Environment Domains (SPEED). Logistic and linear regressions evaluated the association between TEQ and SPEED, and mean SPEED scores and covariates, respectively.

Results

Response rate was 38% (138/363) with representation from all programs. Respondents were mean 30 years of age, 59% men and 25%, 20%, 18%, 24%, and 13% in postgraduate year (PGY) 1–5, respectively. There was no statistically significant association between high/low TEQ scores and mean SPEED score (p = 0.97). There were no statistically significant associations between any of the covariates and high/low TEQ scores (gender, p = 0.21; PGY, p = 0.58; on-versus off-service, p = 0.46) or mean SPEED score (gender, p = 0.95; PGY, p = 0.48; on- versus off-service, p = 0.07). Emergency medicine residents rated their educational environment on average 3.44 (+/- 0.43) out of four. 39 of 134 residents were found to have low empathy.

Conclusion

There was no association between empathy and educational environment. Further research is needed to elucidate modifiable factors contributing to the development of low empathy in emergency medicine residents.

An evaluation of emergency pain management practices in fragility fractures of the pelvis

BACKGROUND

Inadequately treated pain is associated with significant morbidity in older adults. We aimed to describe current pain management practices for patients with fragility pelvic fractures, a common emergency department (ED) presentation in older adults.

METHODS

We performed a health records' review of adults ≥ 65 years old who presented to two academic EDs with nonoperative fragility pelvic fractures between 01/2014 and 09/2018. The primary outcome measures were type and timing of analgesic medications. Secondary outcome measures included ancillary service consultation, ED length of stay, admission rate and rate of return to ED at 30 days. Data were reported using descriptive statistics.

RESULTS

We included 411 patients. The majority were female (339, 82.5%) with mean age 83.9 (SD 8.1) years. Nearly, one-third (130, 31.6%) did not receive any analgesia for their fracture. Analgesia was initiated in 123 (29.9%) patients through paramedic and nursing medical directives; 244 (59.4%) patients received physician-initiated opioids (hydromorphone 228 (55.5%); morphine 28 (6.8%)). Only 23.1% of patients received one or more ancillary services: physiotherapy (10.5%), social work (7.3%), geriatric nurse assessment (14.1%), and homecare (3.9%). Mean ED length of stay was 11.6 (SD 7.1) h; 210 (51.1%) patients were admitted; of those discharged, 45 (22.4%) returned to the ED within 30 days.

CONCLUSION

One in three older adults presenting to the ED with nonoperative fragility pelvic fractures receive no analgesia during the course of their prehospital and ED care. Barriers to quality care must be identified and processes implemented to ensure adequate pain management for this population.

Prevalence, management and outcomes of unrecognized delirium in a National Sample of 1,493 older emergency department patients: how many were sent home and what happened to them?

BACKGROUND

Retrospective studies estimate Emergency Department (ED) delirium recognition at <20%; few prospective studies have assessed delirium recognition and outcomes for patients with unrecognized delirium.

OBJECTIVES

To prospectively measure delirium recognition by ED nurses and physicians, document their confidence in diagnosis and disposition, actual dispositions, and patient outcomes.

METHODS

Prospective observational study of people ≥65 years. We assessed delirium using the Confusion Assessment Method, then asked ED staff if the patient had delirium, confidence in their assessment, if the patient could be discharged, and contacted patients 1 week postdischarge. We report proportions and 95% confidence intervals (Cls).

RESULTS

We enrolled 1,493 participants; mean age was 77.9 years; 49.2% were female, 79 (5.3%, 95% CI 4.2-6.5%) had delirium. ED nurses missed delirium in 43/78 cases (55.1%, 95% CI 43.4-66.4%). Nurses considered 12/43 (27.9%) patients with unrecognized delirium safe to discharge. Median confidence in their delirium diagnosis for patients with unrecognized delirium was 7.0/10. Physicians missed delirium in 10/20 (50.0%, 95% CI 27.2-72.8) cases and considered 2/10 (20.0%) safe to discharge. Median confidence in their delirium diagnosis for patients with unrecognized delirium was 8.0/10. Fifteen patients with unrecognized delirium were sent home: 6.7% died at 1 week follow-up vs. none in those with recognized delirium and 1.1% in the rest of the cohort.

CONCLUSION

Delirium recognition by nurses and physicians was sub-optimal at ~50% and may be associated with increased mortality. Research should explore root causes of unrecognized delirium, and novel strategies to systematically improve delirium recognition and patient outcomes.

Barriers and facilitators to nursing delirium screening in older emergency patients: a qualitative study using the theoretical domains framework

BACKGROUND

delirium is common in older emergency department (ED) patients, but vastly under-recognised, in part due to lack of standardised screening processes. Understanding local context and barriers to delirium screening are integral for successful implementation of a delirium screening protocol.

OBJECTIVES

we sought to identify barriers and facilitators to delirium screening by nurses in older ED patients.

METHODS

we conducted 15 semi-structured, face-to-face interviews based on the Theoretical Domains Framework with bedside nurses, nurse educators and managers at two academic EDs in 2017. Two research assistants independently coded transcripts. Relevant domains and themes were identified.

RESULTS

a total of 717 utterances were coded into 14 domains. Three dominant themes emerged: (i) lack of clinical prioritisation because of competing demands, lack of time and heavy workload; (ii) discordance between perceived capabilities and knowledge and (iii) hospital culture.

CONCLUSION

this qualitative study explored nursing barriers and facilitators to delirium screening in older ED patients. We found that delirium was recognised as an important clinical problem; however, it was not clinically prioritised; there was a false self-perception of knowledge and ability to recognise delirium and hospital culture was a strong influencer of behaviour. Successful adoption of a delirium screening protocol will only be realised if these issues are addressed.

Association between mood disorders and frequent emergency department use: a cross-sectional study

OBJECTIVES

Frequent emergency department (ED) use is a growing problem that is associated with poor patient outcomes and increased health care costs. Our objective was to analyze the association between mood disorders and the incidence of frequent ED use.

METHODS

We used the Canadian Community Health Survey conducted by Statistics Canada, 2015-2016. Mood disorder was defined as depression, bipolar disorder, mania, or dysthymia. Frequent ED use was defined as 4 or more visits in the year preceding the interview. Multivariable log-binomial regression models were used to determine the associations between mood disorders and frequent ED use.

RESULTS

Among the 99,009 participants, 8.4% had mood disorders, 80.3% were younger than 65, and 2.2% were frequent ED users. Mood disorders were significantly associated with the 1-year cumulative incidence of frequent ED use (RR = 2.5, 95% CI 2.2-2.7), after adjusting for several potential confounders.

CONCLUSIONS

This national survey showed that people with a mood disorder had a three-fold risk of frequent ED use, compared to people without mood disorder. These results can inform the development of policies and targeted interventions aimed at identifying and supporting ED patients with mood disorder.

The impact of an outpatient parenteral antibiotic therapy (OPAT) clinic for adults with cellulitis: an interrupted time series study

Emergency department (ED) patients with cellulitis requiring intravenous antibiotics may be eligible for outpatient parenteral antibiotic therapy (OPAT). The primary objective was to determine whether implementation of an OPAT clinic results in decreased hospitalizations and return ED visits for patients receiving OPAT. We conducted an interrupted time series study involving adults with cellulitis presenting to two EDs and treated with intravenous antibiotics. The intervention was the OPAT clinic, which involved follow up at 48-96 h with an infectious disease physician to determine the need for ongoing intravenous antibiotics (implemented January 1, 2014). The primary outcomes were hospital admission and return ED visits within 14 days. Secondary outcomes were treatment failure (admission after initiating OPAT) and adverse peripheral line or antibiotic events. We used an interrupted time series design with segmented regression analysis over one-year pre-intervention and one-year post-intervention. 1666 patients were included. At the end of the study period, there was a non-significant 12% absolute increase in hospital admissions (95% CI - 1.6 to 25.5%; p = 0.084) relative to what would have been expected in the absence of the intervention, but a significant 40.7% absolute reduction in return ED visits (95% CI 25.6-55.9%; p < 0.001). Treatment failure rates were < 2% and adverse events were < 6% in both groups. Implementation of an OPAT clinic significantly reduced return ED visits for cellulitis, but did not reduce hospital admission rates. An ED-to-OPAT clinic model is safe, and has a low rate of treatment failures.

Adverse Events Associated With Electrical Cardioversion in Patients With Acute Atrial Fibrillation and Atrial Flutter

BACKGROUND

We sought to evaluate safety of electrical cardioversion (ECV) for patients with acute atrial fibrillation (AF) or atrial flutter (AFL) in the emergency department (ED).

METHODS

This was an analysis of data from 4 multicentre AF/AFL studies conducted from 2008 to 2019 at 23 large EDs. We included adult patients who received attempts at ECV and who had presented acutely after symptom onset. Staff manually reviewed study and clinical records to abstract data.

RESULTS

We evaluated 1736 ECV cases with a mean age of 60.1 years and 67.1% male. The overall success of ECV was 90.2% (95% confidence interval 88.7%-91.6%), with 4.9% of patients admitted. ED physicians performed the ECV in 95.2% and provided sedation in 96.5%; 13.9% (12.3%-15.7%) of cases experienced important adverse events that required treatment, and 0.4% were classified as life threatening. Another 5.6% had adverse events that did not require treatment. Logistic regression found that the RAFF-3 study cohort (odds ratio [OR] 2.0), age ≥ 85 years (OR 2.1), coronary artery disease (OR 1.5), midazolam (OR 1.9), and fentanyl (OR 1.5) were associated with important adverse events.

CONCLUSIONS

This large evaluation of the safety of ECV for acute AF/AFL in the ED found that while serious adverse events were rare, there were a concerning number of events following sedation that required intervention. Physicians should be aware that older age, coronary artery disease, and fentanyl are associated with higher risks of important adverse events. This study provides more information for shared decision making discussions with patients when choosing between drug-shock and shock-only cardioversion strategies.

Surviving strangulation: evaluation of non-fatal strangulation in patients presenting to a tertiary care sexual assault and partner abuse care program

BACKGROUND

Non-fatal strangulation is a dangerous mechanism of injury among survivors of intimate partner violence and sexual assault, with inadequate evidence to guide investigation in the emergency department (ED). The primary objective is to identify the proportion of intimate partner violence and sexual assault where non-fatal strangulation occurs, and to describe the sequelae of injuries.

METHODS

Health records review of patients treated at the Sexual Assault and Partner Abuse Care Program (SAPACP) and/or Trauma Program at a tertiary level hospital between January 2015 and December 2018. Eligible patients were greater than 16 years old, seen by the SAPACP or trauma team for intimate partner violence and sexual assault, and had a non-fatal strangulation injury. Data were abstracted from the standardized assessment completed by the SAPACP nurse. Descriptive statistics were used.

RESULTS

We identified 209 eligible cases of non-fatal strangulation, among 1791 patient presentations to the SAPACP. Median patient age was 27 years, and 97.6% were female. Computed tomography (CT) of the head was obtained in 22.5%, and CT angiography (CTA) of the head and neck in 6.2% of cases. Eleven significant injuries were identified. Two cases of vascular abnormalities: internal carotid artery indentation with possible intramural hematoma and possible internal carotid artery dissection. Other injuries included delayed bilateral subdural hematomas, a depressed skull fracture, and six nasal fractures.

CONCLUSION

We found over 10% prevalence of non-fatal strangulation in survivors of intimate partner violence and sexual assault. There was a low rate of clinically important injury on the index ED visit secondary to non-fatal strangulation. Severe injury was primarily secondary to concomitant trauma, and utilization of CTA in this cohort was low. Increased awareness is needed among ED physicians regarding the need to consider CTA head and neck.

Point-of-care ultrasound-guided regional anaesthesia in older ED patients with hip fractures: a study to test the feasibility of a training programme and time needed to complete nerve blocks by ED physicians after training

OBJECTIVES

Point-of-care ultrasound-guided regional anaesthesia (POCUS-GRA) provides safe, rapid analgesia for older people with hip fractures but is rarely performed in the emergency department (ED). Self-perceived inadequate training and time to perform POCUS-GRA are the two most important barriers. Our objective is to assess the feasibility of a proposed multicentre, stepped-wedge cluster randomised clinical trial (RCT) to assess the impact of a knowledge-to-practice (KTP) intervention on delirium.

DESIGN

Open-label feasibility study.

SETTING

An academic tertiary care Canadian ED (annual visits 60 000).

PARTICIPANTS

Emergency physicians working at least one ED shift per week, excluding those already performing POCUS-GRA more than four times per year.

INTERVENTION

A KTP intervention, including 2-hour structured training sessions with procedure bundle and email reminders.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary feasibility outcome is the proportion of eligible physicians that completed training and subsequently performed POCUS-GRA. Secondary outcome is the time needed to complete POCUS-GRA. We also test the feasibility of the enrolment, consent and randomisation processes for the future stepped-wedge cluster RCT (NCT02892968).

RESULTS

Of 36 emergency physicians, 4 (12%) were excluded or declined participation. All remaining 32 emergency physicians completed training and 31 subsequently treated at least one eligible patient. Collectively, 27/31 (87.1%) performed 102 POCUS-GRA blocks (range 1-20 blocks per physician). The median (IQR) time to perform blocks was 15 (10-20) min, and reduction in pain was 6/10 (3-7) following POCUS-GRA. There were no reported complications.

CONCLUSION

Our KTP intervention, consent process and randomisation were feasible. The time to perform POCUS-GRA rarely exceeded 30 min, Our findings reinforce the existing data on the safety and effectiveness of POCUS-GRA, mitigate perceived barriers to more widespread adoption and demonstrate the feasibility of trialling this intervention for the proposed stepped-wedge cluster RCT.

Which older emergency patients are at risk of intracranial bleeding after a fall? A protocol to derive a clinical decision rule for the emergency department

INTRODUCTION

Falling on level ground is now the most common cause of traumatic intracranial bleeding worldwide. Older adults frequently present to the emergency department (ED) after falling. It can be challenging for clinicians to determine who requires brain imaging to rule out traumatic intracranial bleeding, and often head injury decision rules do not apply to older adults who fall. The goal of our study is to derive a clinical decision rule, which will identify older adults who present to the ED after a fall who do not have clinically important intracranial bleeding.

METHODS AND ANALYSIS

This is a prospective cohort study enrolling patients aged 65 years or older, who present to the ED of 11 hospitals in Canada and the USA within 48 hours of having a fall. Patients are included if they fall on level ground, off a chair, toilet seat or out of bed. The primary outcome is the diagnosis of clinically important intracranial bleeding within 42 days of the index ED visit. An independent adjudication committee will determine the primary outcome, blinded to all other data. We are collecting data on 17 potential predictor variables. The treating physician completes a study data form at the time of initial assessment, prior to brain imaging. Data extraction is supplemented by an independent, structured electronic medical record review. We will perform binary recursive partitioning using Classification and Regression Trees to derive a clinical decision rule.

ETHICS AND DISSEMINATION

The study was initially approved by the Hamilton Integrated Research Ethics Committee and subsequently approved by the research ethics boards governing all participating sites. We will disseminate our results by journal publication, presentation at international meetings and social media.

NCT03745755.

Impact of a geriatric consultation service on outcomes in older trauma patients: a before-after study

PURPOSE

Early geriatric involvement is recommended for older trauma patients. We wished to determine the impact of geriatric consultation on mortality, hospital length of stay and discharge disposition in older patients who were admitted to our Level 1 trauma unit.

METHODS

We completed a health records review of trauma unit patients, age ≥ 75 years old with Injury Severity Score (ISS) ≥ 12, before (11/2015-10/2017) and after (11/2017-10/2019) implementation of a geriatric trauma consultation initiative. Primary outcomes were mortality, hospital length of stay and discharge destination. Secondary objectives were adherence to the geriatric trauma consult process and identification of geriatric-specific issues. A multivariable analysis controlling for age, gender, multi-morbidity and ISS was undertaken.

RESULTS

157 patients pre-implementation and 172 post-implementation with mean age 83.8 years and 53.8% females were included. Geriatric consultation had no impact on in-hospital mortality [OR 0.70 (95% CI 0.31-1.58)] or length of stay [ß 0.68 (95%CI - 1.35-2.72)]. Patients who received a geriatric consultation were more likely to be discharged home (OR 2.01 (95% CI 1.24-3.24). The adherence to consultation process was 99.4%. Mobility, pain and cognitive impairment were the most common geriatric concerns, identified in 76.6, 61.1 and 50.0% of older trauma patients, respectively.

CONCLUSION

Older trauma patients that receive geriatric trauma consultation are more likely to be discharged home. Collaboration between trauma and geriatric specialists is beneficial and may lead to meaningful improvements in outcomes for older trauma patients.

Rapid Fire: Acute Brain Failure in Older Emergency Department Patients

Delirium is common in older emergency department (ED) patients. Although associated with significant morbidity and mortality, it often goes unrecognized. A consistent approach to evaluation of mental status, including use of validated tools, is key to diagnosing delirium. Identification of the precipitating event requires thorough evaluation, including detailed history, medication reconciliation, physical examination, and medical work-up, for causes of delirium. Management is aimed at identifying and treating the underlying cause. Meaningful improvements in delirium care can be achieved when prevention, identification, and management of older delirious ED patients is integrated by physicians and corresponding frameworks implemented at the health system level.

Adverse Events Among Emergency Department Patients With Cardiovascular Conditions: A Multicenter Study

STUDY OBJECTIVE

We aim to determine incidence and type of adverse events (adverse outcomes related to emergency care) among emergency department (ED) patients discharged with recent-onset atrial fibrillation, acute heart failure, and syncope.

METHODS

This 5-year prospective cohort study included high-acuity adult patients discharged with the 3 sentinel diagnoses from 6 tertiary care Canadian EDs. We screened all ED visits for eligibility and performed telephone interviews 14 days postdischarge to identify flagged outcomes: death, hospital admission, return ED visit, health care provider visit, and new or worsening symptoms. We created case summaries describing index ED visit and flagged outcomes, and trained emergency physicians reviewed case summaries to identify adverse events. We reported adverse event incidence and rates with 95% confidence intervals and contributing factor themes.

RESULTS

Among 4,741 subjects (mean age 70.2 years; 51.2% men), we observed 170 adverse events (3.6 per 100 patients; 95% confidence interval 3.1 to 4.2). Patients discharged with acute heart failure were most likely to experience adverse events (5.3%), followed by those with atrial fibrillation (2.0%) and syncope (0.8%). We noted variation in absolute adverse event rates across sites from 0.7 to 6.0 per 100 patients. The most common adverse event types were management issues, diagnostic issues, and unsafe disposition decisions. Frequent contributing factor themes included failure to recognize underlying causes and inappropriate management of dual diagnoses.

CONCLUSION

Among adverse events after ED discharge for patients with these 3 sentinel cardiovascular diagnoses, we identified quality improvement opportunities such as strengthening dual diagnosis detection and evidence-based clinical practice guideline adherence.

Physician choices in pulmonary embolism testing

BACKGROUND

Evidence-based guidelines advise excluding pulmonary embolism (PE) diagnosis using d-dimer in patients with a lower probability of PE. Emergency physicians frequently order computed tomography (CT) pulmonary angiography without d-dimer testing or when d-dimer is negative, which exposes patients to more risk than benefit. Our objective was to develop a conceptual framework explaining emergency physicians' test choices for PE.

METHODS

We conducted a qualitative study using in-depth interviews of emergency physicians in Canada. A nonmedical researcher conducted in-person interviews. Participants described how they would test simulated patients with symptoms of possible PE, answered a knowledge test and were interviewed on barriers to using evidence-based PE tests.

RESULTS

We interviewed 63 emergency physicians from 9 hospitals in 5 cities, across 3 provinces. We identified 8 domains: anxiety with PE, barriers to using the evidence (time, knowledge and patient), divergent views on evidence-based PE testing, inherent Wells score problems, the drive to obtain CT rather than to diagnose PE, gestalt estimation artificially inflating PE probability, subjective reasoning and cognitive biases supporting deviation from evidence-based tests and use of evidence-based testing to rule out PE in patients who are very unlikely to have PE. Choices for PE testing were influenced by the disease, environment, test qualities, physician and probability of PE.

INTERPRETATION

Analysis of structured interviews with emergency physicians provided a conceptual framework to explain how these physicians use tests for suspected PE. The data suggest 8 domains to address when implementing an evidence-based protocol to investigate PE.

The role of laboratories in animal-related disasters and emergencies

This paper outlines the role of laboratories in animal-health-related disasters and emergencies, with a particular focus on biological threats - intentional, accidental and natural. Whilst multisectoral coordination is increasingly recognised as necessary for effective preparedness and response to all kinds of disasters, the role of the laboratory is often overlooked. The laboratories' involvement, not just in the response, but across all phases of disaster management - mitigation, planning, response and recovery - is essential, not only for improved animal health but for preservation of livelihoods and for food security, social cohesion and economic stability.

Evaluation of the Ottawa 3DY as a screening tool for cognitive impairment in older emergency department patients

OBJECTIVE

This study sought to evaluate the implementation of the Ottawa 3DY Tool, a simple screening instrument for cognitive impairment, by front-line ED clinicians.

METHODS

We conducted a prospective cohort study in an academic ED. Patients ≥75 years underwent cognitive screening with the Ottawa 3DY by front-line nurses and physicians. Descriptive statistics were used to describe level of implementation and acceptability of the tool. Sensitivity and specificity was calculated using an Mini-Mental State Exam <25 as the cut-off for cognitive impairment. A weighted kappa was calculated to establish inter-rater agreement.

RESULTS

Cognitive screening was completed in 260/332 eligible patients (78.3%), who were 60% female and had a mean age of 83.7 years. Facilitators to screening: perceived importance and ownership of screening and feasibility of Ottawa 3DY. Barriers to screening were: over confidence in clinical judgement and perceived lack of patient benefit. Ottawa 3DY had a sensitivity of 84.6% (64.3-95.0) and specificity of 54.2% (39.3-68.4) when completed by nurses. When completed by emergency physicians, sensitivity was 78.9% (53.9-93.0) and specificity was 70.0% (45.7-87.2). Inter-rater agreement kappa score was 0.67.

DISCUSSION

This study demonstrated that incorporating the Ottawa 3DY tool into the routine evaluation of older ED patients by front-line ED clinicians is both feasible and effective. With its demonstrated good inter-rater reliability and moderate level of sensitivity and specificity when compared with the much longer MMSE, the routine adoption of this tool may help lead to improved recognition of cognitive impairment and ultimately patient and system outcomes.
