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.

Availability of Emergency Department Wait Times Information: A Patient-Centered Needs Assessment.

INTRODUCTION: Many Emergency Departments (ED) publish wait times; however, the patient perspective in what information is requested and the quantity of information to post is limited. METHODS: We conducted a mixed-methods study at a tertiary care academic center. First, we conducted focus groups of 7 patients. We then generated themes following content analysis to create a patient survey. We administered in-person surveys to patients in ED waiting rooms at sites randomized for survey administration. We used preassigned shifts utilized for even patient perspective representation of the 24 hours-a-day/7 days-a-week service. We included waiting room patients over 18 years of age and excluded patients directly referred to a specialty service or who did not speak French or English. We analyzed survey data using descriptive statistics. RESULTS: We identified nine dominant focus group themes: wait time definition, wait time notification, communication, education, patient expectations, utilization of the ED, patient behaviour, physical comfort, and patient empowerment. Of the 240 patient questionnaires administered, 81.3% of respondents wanted to know ED wait times before hospital arrival hospital and 90.8% wanted ED wait times posted in the waiting room. Website (46.7%) was the most popular choice for publishing wait times outside the ED. Within the ED, patients had no preference regarding display modality, if times were displayed (39.6%). Overall, 76.7% stated that their satisfaction with the ED would be improved if wait times were posted. CONCLUSION: ED patients strongly supported having access to wait time information. Patients believed having wait time information will have a positive impact on their overall ED satisfaction.

Preadmission Antiplatelet Use and Associated Outcomes and Costs Among ICU Patients With Intracranial Hemorrhage.

INTRODUCTION: Patients with intracranial hemorrhage (including intracerebral hemorrhage, subarachnoid hemorrhage, and traumatic hemorrhage) are commonly admitted to the intensive care unit (ICU). Although indications for oral antiplatelet agents are increasing, the impact of preadmission use on outcomes in patients with intracranial hemorrhage admitted to the ICU is unknown. We sought to evaluate the association between preadmission oral antiplatelet use, in-hospital mortality, resource utilization, and costs among ICU patients with intracranial hemorrhage. METHODS: We retrospectively analyzed a prospectively collected registry (2011-2016) and included consecutive adult patients from 2 hospitals admitted to ICU with intracranial hemorrhage. Patients were categorized on the basis of preadmission oral antiplatelet use. We excluded patients with preadmission anticoagulant use. The primary outcome was in-hospital mortality and was analyzed using a multivariable logistic regression model. Contributors to total hospital cost were analyzed using a generalized linear model with log link and gamma distribution. RESULTS: Of 720 included patients with intracranial hemorrhage, 107 (14.9%) had been using an oral antiplatelet agent at the time of ICU admission. Oral antiplatelet use was not associated with in-hospital mortality (adjusted odds ratio: 1.31 [95% confidence interval [CI]: 0.93-2.22]). Evaluation of total costs also revealed no association with oral antiplatelet use (adjusted ratio of means [aROM]: 0.92 [95% CI: 0.82-1.02, P = .10]). Total cost among patients with intracranial hemorrhage was driven by illness severity (aROM: 1.96 [95% CI: 1.94-1.98], P < .001), increasing ICU length of stay (aROM: 1.05 [95% CI: 1.05-1.06], P < .001), and use of invasive mechanical ventilation (aROM: 1.76 [95% CI: 1.68-1.86], P < .001). CONCLUSIONS: Among ICU patients admitted with intracranial hemorrhage, preadmission oral antiplatelet use was not associated with increased in-hospital mortality or hospital costs. These findings have important prognostic implications for clinicians who care for patients with intracranial hemorrhage.

Lung-Protective Ventilation and Associated Outcomes and Costs Among Patients Receiving Invasive Mechanical Ventilation in the ED.

BACKGROUND: Invasive mechanical ventilation is often initiated in the ED, and mechanically ventilated patients may be kept in the ED for hours before ICU transfer. Although lung-protective ventilation is beneficial, particularly in ARDS, it remains uncertain how often lung-protective tidal volumes are used in the ED, and whether lung-protective ventilation in this setting impacts patient outcomes. RESEARCH QUESTION: What is the association between the use of lung-protective ventilation in the ED and outcomes among invasively ventilated patients? STUDY DESIGN AND METHODS: A retrospective analysis (2011-2017) of a prospective registry from eight EDs enrolling consecutive adult patients (≥ 18 years) who received invasive mechanical ventilation in the ED was performed. Lung-protective ventilation was defined by use of tidal volumes ≤ 8 mL/kg predicted body weight. The primary outcome was hospital mortality. Secondary outcomes included development of ARDS, hospital length of stay, and total hospital costs. RESULTS: The study included 4,174 patients, of whom 2,437 (58.4%) received lung-protective ventilation in the ED. Use of lung-protective ventilation was associated with decreased odds of hospital death (adjusted OR [aOR], 0.91; 95% CI, 0.84-0.96) and development of ARDS (aOR, 0.87; 95% CI, 0.81-0.92). Patients who received lung-protective ventilation in the ED had shorter median duration of mechanical ventilation (4 vs 5 days; P < 0.01), shorter median hospital length of stay (11 vs 14 days; P < .001), and reduced total hospital costs (Can$44,348 vs Can$52,484 [US$34,153 vs US$40,418]; P = .03) compared with patients who received higher tidal volumes. INTERPRETATION: Use of lung-protective ventilation in the ED was associated with important patient- and system-centered outcomes, including lower hospital mortality, decreased incidence of ARDS, lower hospital length of stay, and decreased total costs. Protocol development promoting the regular use of lung-protective ventilation in the ED may be of value.

An environmental scan of emergency medicine research support, training, and infrastructure across Canada.

OBJECTIVE: Our study objective was to describe the Canadian emergency medicine (EM) research community landscape prior to the initiation of a nationwide network. METHODS: A two-phase electronic survey was sent to 17 Canadian medical schools. The Phase 1 Environmental Scan was administered to department chairs/hospital EM chiefs, to identify EM physicians conducting clinical or educational research. The Phase 2 Survey was sent to the identified EM researchers to assess four themes: 1) geographic distribution, 2) training/career satisfaction, 3) time/financial compensation, and 4) research facilitators/barriers. Descriptive analyses were conducted, and results were stratified by Canadian regions. RESULTS: A total of 92 EM researchers were identified in Phase 1; 67 (73%) responded to the Phase 2 Survey. Of those, 42 (63%) reported being clinical researchers, and 19 (45%) had a graduate degree. Three provinces encompassed most of the researchers (n = 35). Of the respondents, 61% had a research degree, 66% felt adequately trained for their research career, 73% had financial support, 83% had access to office spaces, 52% had no mentor during their first years of their career, 69% felt satisfied with their research career, and 82% suggested that they will still be conducting research in 5 years. CONCLUSION: EM researchers reported being adequately trained, even though only a little over half had a graduate degree. Only two-thirds had financial support, and mentorship was lacking in one-third of the participants. Not all respondents had a form of infrastructure, but most felt optimistic about their careers. The Canadian EM research environment could be improved to ensure better research capacity.

Frailty and associated outcomes and resource utilization following in-hospital cardiac arrest.

BACKGROUND: In-hospital cardiac arrest (IHCA) is common and associated with high mortality. Frailty is increasingly recognized as a predictor of worse prognosis among critically ill patients, but its association with outcomes and resource utilization following IHCA is unknown. METHODS: We performed a retrospective analysis (2013-2016) of a prospectively collected registry from two hospitals of consecutive hospitalized adult patients with IHCA occurring on the hospital wards. We defined frailty using the Clinical Frailty Scale (CFS) score ≥5. CFS scores were based on validated medical review criteria. The primary outcome is hospital mortality. Secondary outcomes include return of spontaneous circulation (ROSC), discharge to long-term care, and hospital costs. We used multivariable logistic regression to adjust for known confounders. RESULTS: We included 477 patients, and 124 (26.0%) had frailty. Frailty was associated with increased odds of hospital death (adjusted odds ratio [aOR]: 2.91 [95% confidence interval [CI]: 2.37-3.48) and discharge to long-term care (aOR 1.94 [95% CI: 1.57-2.32]). Compared with patients without frailty, patients with frailty had decreased odds of ROSC following IHCA (aOR 0.63 [95% CI: 0.41-0.93]). No difference in mean total costs was demonstrated between patients with and without frailty ($50,799 vs. $45,849). Frail patients did have higher cost-per-survivor ($947,546 vs. $161,550). CONCLUSIONS: Frail individuals who experience an IHCA are more likely to die in hospital or be discharged to long-term care, and less likely to achieve ROSC in comparison with individuals who are not frail. The hospital costs per-survivor of IHCA are increased when frailty is present.

Emergency Department disposition decisions and associated mortality and costs in ICU patients with suspected infection.

BACKGROUND: Following emergency department (ED) assessment, patients with infection may be directly admitted to the intensive care unit (ICU) or alternatively admitted to hospital wards or sent home. Those admitted to the hospital wards or sent home may experience future deterioration necessitating ICU admission. METHODS: We used a prospectively collected registry from two hospitals within a single tertiary care hospital network between 2011 and 2014. Patient information, outcomes, and costs were stored in the hospital data warehouse. Patients were categorized into three groups: (1) admitted directly from the ED to the ICU; (2) initially admitted to the hospital wards, with ICU admission within 72 hours of initial presentation; or (3) sent home from the ED, with ICU admission within 72 hours of initial presentation. Using multivariable logistic regression, we sought to compare outcomes and total costs between groups. Total costs were evaluated using a generalized linear model. RESULTS: A total of 657 patients were included; of these, 338 (51.4%) were admitted directly from the ED to the ICU, 246 (37.4%) were initially admitted to the wards and then to the ICU, and 73 (11.1%) were initially sent home and then admitted to the ICU. In-hospital mortality was lowest among patients admitted directly to the ICU (29.5%), as compared with patients admitted to the ICU from wards (42.7%) or home (61.6%) (P < 0.001). As compared with direct ICU admission, disposition to the ward was associated with an adjusted OR of 1.75 (95% CI, 1.22-2.50; P < 0.01) for mortality, and disposition home was associated with an adjusted OR of 4.02 (95% CI, 2.32-6.98). Mean total costs were lowest among patients directly admitted to the ICU ($26,748), as compared with those admitted from the wards ($107,315) and those initially sent home ($71,492) (P < 0.001). Cost per survivor was lower among patients directly admitted to the ICU ($37,986) than either those initially admitted to the wards ($187,230) or those sent home ($186,390) (P < 0.001). CONCLUSIONS: In comparison with direct admission to the ICU, patients with suspected infection admitted to the ICU who have previously been discharged home or admitted to the ward are associated with higher in-hospital mortality and costs.

Outcomes and Costs of Patients Admitted to the ICU Due to Spontaneous Intracranial Hemorrhage.

OBJECTIVES: Spontaneous intracranial hemorrhage, including subarachnoid hemorrhage and intracerebral hemorrhage, is associated with significant morbidity and mortality. Although many of these patients will require ICU admission, little is known regarding their outcomes and the costs incurred. We evaluated this population in order to identify outcomes and cost patterns. DESIGN: Retrospective cohort analysis of a health administrative database. SETTING: Two ICUs within a single hospital system. PATIENTS: Eight-thousand four-hundred forty-seven patients admitted to ICU from 2011 to 2014, of whom 332 had a diagnosis of spontaneous intracranial hemorrhage. Control patients were defined as randomly selected age, sex, and comorbidity index-matched nonintracranial hemorrhage ICU patients (1:4 matching ratio). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Mean age of ICU intracranial hemorrhage patients was 60.1 years, and 120 (36.1%) died prior to discharge. Intracranial hemorrhage was associated with a mean total cost of $75,869, compared with $52,471 in control patients (p < 0.01). Mean cost per survivor of intracranial hemorrhage patients was $118,813. Subarachnoid hemorrhage was associated with significantly higher mean total costs than intracerebral hemorrhage ($92,794 vs $53,491; p < 0.01) and higher mean cost per day ($4,377 vs $3,604; p < 0.01). Patients with intracranial hemorrhage who survived to hospital discharge were significantly costlier than decedents ($100,979 vs $30,872; p < 0.01). Intracranial hemorrhage associated with oral anticoagulant use had a mean total cost of $152,373, compared with $66,548 in nonoral anticoagulant intracranial hemorrhage (p < 0.01). CONCLUSIONS: Patients admitted to ICU with intracranial hemorrhage have high costs and high mortality, leading to elevated cost per survivor. Subarachnoid hemorrhage patients incur greater costs than intracerebral hemorrhage patients, and oral anticoagulant-associated intracerebral hemorrhage is particularly costly. Our findings provide novel information regarding financial impact of this common ICU population.

Prognostic Accuracy of the Quick Sequential Organ Failure Assessment for Mortality in Patients With Suspected Infection: A Systematic Review and Meta-analysis.

Background: The quick Sequential Organ Failure Assessment (qSOFA) has been proposed for prediction of mortality in patients with suspected infection. Purpose: To summarize and compare the prognostic accuracy of qSOFA and the systemic inflammatory response syndrome (SIRS) criteria for prediction of mortality in adult patients with suspected infection. Data Sources: Four databases from inception through November 2017. Study Selection: English-language studies using qSOFA for prediction of mortality (in-hospital, 28-day, or 30-day) in adult patients with suspected infection in the intensive care unit (ICU), emergency department (ED), or hospital wards. Data Extraction: Two investigators independently extracted data and assessed study quality using standard criteria. Data Synthesis: Thirty-eight studies were included (n = 385 333). qSOFA was associated with a pooled sensitivity of 60.8% (95% CI, 51.4% to 69.4%) and a pooled specificity of 72.0% (CI, 63.4% to 79.2%) for mortality. The SIRS criteria were associated with a pooled sensitivity of 88.1% (CI, 82.3% to 92.1%) and a pooled specificity of 25.8% (CI, 17.1% to 36.9%). The pooled sensitivity of qSOFA was higher in the ICU population (87.2% [CI, 75.8% to 93.7%]) than the non-ICU population (51.2% [CI, 43.6% to 58.7%]). The pooled specificity of qSOFA was higher in the non-ICU population (79.6% [CI, 73.3% to 84.7%]) than the ICU population (33.3% [CI, 23.8% to 44.4%]). Limitation: Potential risk of bias in included studies due to qSOFA interpretation and patient selection. Conclusion: qSOFA had poor sensitivity and moderate specificity for short-term mortality. The SIRS criteria had sensitivity superior to that of qSOFA, supporting their use for screening of patients and as a prompt for treatment initiation.

The immigrant effect: factors impacting use of primary and emergency department care - a Canadian population cross-sectional study.

OBJECTIVE: In 2011, Canada had a foreign-born population of approximately 6,775,800. They represented 20.6% of the total population. Immigrants possess characteristics that reduce the use of primary care. This is thought to be, in part, due to a lower education level, employment, and better health status. Our objective was to assess whether, in an immigrant population without a primary care physician, similar socioeconomic factors would also reduce the likelihood of using the emergency department compared to a non-immigrant population without primary care. METHODS: Data regarding individuals ≥ 12 years of age from the Canadian Community Health Survey from 2007 to 2008 were analysed (n=134,073; response rate 93%). Our study population comprised 15,554 individuals identified without a primary care physician who had a regular place for medical care. The primary outcome was emergency department as a regular care access point. Socioeconomic variables included employment, health status, and education. Covariates included chronic health conditions, mobility, gender, age, and mental health. Weighted logistic regression models were constructed to evaluate the importance of individual risk factors. RESULTS: The sample of 15,554 (immigrants n=1,767) consisted of 57.3% male and 42.7% female respondents from across Canada. Immigrants were less likely than Canadian-born respondents to use the emergency department as a regular access point for health care (odds ratio=0.48 [95% CI 0.40 - 0.57]). Adjusting for health, education, or employment had no effect on this reduced tendency (odds ratio=0.47 [95% CI 0.38 - 0.58]). CONCLUSION: In a Canadian population without a primary care physician, immigrants are less likely to use the emergency department as a primary access point for care than Canadian-born respondents. However, this effect is independent of previously reported social and economic factors that impact use of primary care. Immigration status is an important but complex component of racial and ethnic disparity in the use of health care in Canada.

Factors associated with choosing the emergency department as the primary access point to health care: a Canadian population cross-sectional study.

OBJECTIVE: Approximately 4.3 million Canadians are without a primary care physician, of which 13% choose the emergency department (ED) as their regular access point to health care. We sought to identify factors associated with preferential ED use over other health services. We hypothesized that socioeconomic barriers (i.e., employment, health status, education) to primary care would also prevent access to ED alternatives. METHODS: Data from the Canadian Community Health Survey, 2007 to 2008, were analysed (N=134,073; response rate 93.5%). Our study population comprised 14,091 individuals identified without a primary care physician. Socioeconomic variables included employment, health, and education. Covariates included chronic health conditions, immigrant status, gender, age, and mental health. Prevalence estimates and 95% confidence intervals (CIs) for each variable were calculated. Weighted logistic regression models were constructed to evaluate the importance of individual risk factors and their interactions after adjustment for relevant covariates. RESULTS: The sample comprised 57.2% males from across Canada. Employment (OR 0.73 [95% CI: 0.59-0.90]), good health (OR 0.73 [95% CI 0.57-0.88]), and post-secondary education (OR 0.68 [95% CI 0.53-0.88]) reduced respondents use of the ED. The reduced odds of ED use were independent of chronic conditions, mental health, gender, poor mobility, province, and age. CONCLUSIONS: Low socioeconomic status dictates preferential ED use in those without a primary care physician. Specific policy and system development targeting this at-risk population are indicated to alter ED use patterns in this population.

Development of the Canadian Syncope Risk Score to predict serious adverse events after emergency department assessment of syncope.

BACKGROUND: Syncope can be caused by serious conditions not evident during initial evaluation, which can lead to serious adverse events, including death, after disposition from the emergency department. We sought to develop a clinical decision tool to identify adult patients with syncope who are at risk of a serious adverse event within 30 days after disposition from the emergency department. METHODS: We prospectively enrolled adults (age ≥ 16 yr) with syncope who presented within 24 hours after the event to 1 of 6 large emergency departments from Sept. 29, 2010, to Feb. 27, 2014. We collected standardized variables at index presentation from clinical evaluation and investigations. Adjudicated serious adverse events included death, myocardial infarction, arrhythmia, structural heart disease, pulmonary embolism, serious hemorrhage and procedural interventions within 30 days. RESULTS: We enrolled 4030 patients with syncope; the mean age was 53.6 years, 55.5% were women, and 9.5% were admitted to hospital. Serious adverse events occurred in 147 (3.6%) of the patients within 30 days after disposition from the emergency department. Of 43 candidate predictors examined, we included 9 in the final model: predisposition to vasovagal syncope, heart disease, any systolic pressure reading in the emergency department < 90 or > 180 mm Hg, troponin level above 99th percentile for the normal population, abnormal QRS axis (< -30° or > 100°), QRS duration longer than 130 ms, QTc interval longer than 480 ms, emergency department diagnosis of cardiac syncope and emergency department diagnosis of vasovagal syncope (C statistic 0.88, 95% confidence interval [CI] 0.85-0.90; optimism 0.015; goodness-of-fit p = 0.11). The risk of a serious adverse event within 30 days ranged from 0.4% for a score of -3 to 83.6% for a score of 11. The sensitivity was 99.2% (95% CI 95.9%-100%) for a threshold score of -2 or higher and 97.7% (95% CI 93.5%-99.5%) for a threshold score of -1 or higher. INTERPRETATION: The Canadian Syncope Risk Score showed good discrimination and calibration for 30-day risk of serious adverse events after disposition from the emergency department. Once validated, the tool will be able to accurately stratify the risk of serious adverse events among patients presenting with syncope, including those at low risk who can be discharged home quickly.

CAEP 2014 Academic symposium: "How to make research succeed in your department: How to fund your research program".

OBJECTIVE: We sought to gather a comprehensive list of funding strategies and opportunities for emergency medicine (EM) centres across Canada, and make recommendations on how to successfully fund all levels of research activity, including research projects, staff salaries, infrastructure, and researcher stipends. METHODS: We formed an expert panel consisting of volunteers recognized nationally for their scholarly work in EM. First, we conducted interviews with academic leaders and researchers to obtain a description of their local funding strategies using a standardized open-ended questionnaire. Panelists then identified emerging funding models. Second, we listed funding opportunities and initiatives at the provincial, national, and international levels. Finally, we used an iterative consensus-based approach to derive pragmatic recommendations after incorporating comments and suggestions from participants at an academic symposium. RESULTS: Our review of funding strategies identified four funding models: 1) investigator dependent model, 2) practice plan, 3) generous benefactor, and 4) mixed funding. Recommendations in this document include approaches for research contributors and producers (seven recommendations), for local academic leaders (five recommendations), and for national organizations, such as the Canadian Association of Emergency Physicians (CAEP) (three recommendations). CONCLUSIONS: Funding for research in EM varies across Canada and is largely insecure. We offer recommendations to help facilitate funding for large and small projects, for salary support, and for local and national leaders to advance EM research. We believe that these recommendations will increase funding for all levels of EM research activity, including research projects, staff salaries, infrastructure, and researcher stipends.

A prospective cohort study of patients with transient ischemic attack to identify high-risk clinical characteristics.

BACKGROUND AND PURPOSE: The occurrence of a transient ischemic attack (TIA) increases an individual's risk for subsequent stroke. The objectives of this study were to determine clinical features of patients with TIA associated with impending (≤7 days) stroke and to develop a clinical prediction score for impending stroke. METHODS: We conducted a prospective cohort study at 8 Canadian emergency departments for 5 years. We enrolled patients with a new TIA. Our outcome was subsequent stroke within 7 days of TIA diagnosis. RESULTS: We prospectively enrolled 3906 patients, of which 86 (2.2%) experienced a stroke within 7 days. Clinical features strongly correlated with having an impending stroke included first-ever TIA, language disturbance, longer duration, weakness, gait disturbance, elevated blood pressure, atrial fibrillation on ECG, infarction on computed tomography, and elevated blood glucose. Variables less associated with having an impending stroke included vertigo, lightheadedness, and visual loss. From this cohort, we derived the Canadian TIA Score which identifies the risk of subsequent stroke≤7 days and consists of 13 variables. This model has good discrimination with a c-statistic of 0.77 (95% confidence interval, 0.73-0.82). CONCLUSIONS: Patients with TIA with their first TIA, language disturbance, duration of symptoms≥10 minutes, gait disturbance, atrial fibrillation, infarction on computed tomography, elevated platelets or glucose, unilateral weakness, history of carotid stenosis, and elevated diastolic blood pressure are at higher risk for an impending stroke. Patients with vertigo and no high-risk features are at low risk. The Canadian TIA Score quantifies the impending stroke risk following TIA.

Assessment of the impact on time to complete medical record using an electronic medical record versus a paper record on emergency department patients: a study.

BACKGROUND: Electronic medical records are becoming an integral part of healthcare delivery. OBJECTIVE: The goal of this study was to compare paper documentation versus electronic medical record for non-traumatic chest pain to determine differences in time for physicians to complete medical records using paper versus electronic mediums. We also assessed physician satisfaction with the electronic format. METHODS: We conducted this before-after study in a single large tertiary care academic emergency department. In the 'Before Period', stopwatches determined the time for paper medical recording. In the 'After Period', a template-based electronic medical record was introduced and the time for electronic recording was measured. The time to record in the before and after periods were compared using a two-sided t test. We surveyed physicians to assess satisfaction. RESULTS: We enrolled 100 non-traumatic patients with chest pain in the before period and 73 in the after period. The documentation time was longer using electronic charting, (9.6±5.9 min vs 6.1±2.5 min; p<0.001). 18 of 20 physicians participating in the after period completed surveys. Physicians were not satisfied with the electronic patient recording for non-traumatic chest pain. CONCLUSIONS: This is the first study that we are aware of which compared paper versus electronic medical records in the emergency department. Electronic recording took longer than paper records. Physicians were not satisfied using this electronic record. Given the time pressures on emergency physicians, a solution to minimise the charting time using electronic medical records must be found before widespread uptake of electronic charting will be possible.

Survey of emergency physicians' requirements for a clinical decision rule for acute respiratory illnesses in three countries.

UNLABELLED: ABSTRACTObjective:There are currently no widely used guidelines to determine which older patients with acute respiratory conditions require hospital admission. This study assessed the need for clinical decision rules to help determine whether hospital admission is required for patients over 50 years for three common respiratory conditions: chronic obstructive pulmonary disease (COPD), heart failure (HF), and community-acquired pneumonia (CAP). DESIGN: Postal survey. SETTING: Emergency physicians (EPs) from the United States, Canada, and Australasia. PARTICIPANTS: A random sample of EPs from the United States, Canada, and Australasia. INTERVENTIONS: A modified Dillman technique with a prenotification letter and up to three postal surveys. MAIN OUTCOMES: EP opinions regarding the need for and willingness to use clinical decision rules for emergency department (ED) patients over 50 years with COPD, HF, or CAP to predict hospital admission. We assessed the required sensitivity of each rule for return ED visit or death within 14 days. RESULTS: A total of 801 responses from 1,493 surveys were received, with response rates of 55%, 60%, and 46% for Australasia, Canada, and the United States, respectively. Over 90% of EPs reported that they would consider using clinical decision rules for HF, CAP, and COPD. The median required sensitivity for death within 14 days was 97 to 98% for all conditions. CONCLUSIONS: EPs are likely to adopt highly sensitive clinical decision rules to predict the need for hospital admission for patients over 50 years with COPD, HF, or CAP.

Derivation of a clinical decision rule for chest radiography in emergency department patients with chest pain and possible acute coronary syndrome.

OBJECTIVE: We derived a clinical decision rule to determine which emergency department (ED) patients with chest pain and possible acute coronary syndrome (ACS) require chest radiography. METHODS: We prospectively enrolled patients over 24 years of age with a primary complaint of chest pain and possible ACS over a 6 month period. Emergency physicians completed standardized clinical assessments and ordered chest radiographs as appropriate. Two blinded investigators independently classified chest radiographs as "normal," "abnormal not requiring intervention" and "abnormal requiring intervention," based on review of the radiology report and the medical record. The primary outcome was abnormality of chest radiographs requiring acute intervention. Analyses included interrater reliability assessment (with kappa statistics), univariate analyses and recursive partitioning. RESULTS: We enrolled 529 patients during the study period between Jul. 1, 2007, and Dec. 31, 2007. Patients had a mean age of 59.9 years, 60.3% were male, 4.0% had a history of congestive heart failure and 21.9% had a history of acute myocardial infarction. Only 2.1% (95% confidence interval [CI] 1.1%-3.8%) of patients had radiographic abnormality of the chest requiring acute intervention. The kappa statistic for chest radiograph classification was 0.81 (95% CI 0.66-0.95). We derived the following rule: patients can forgo chest radiography if they have no history of congestive heart failure, no history of smoking and no abnormalities on lung auscultation. The rule was 100% sensitive (95% CI 32.0%-40.4%) and 36.1% specific (95% CI 32.0%-40.4%). CONCLUSION: This rule has potential to reduce health care costs and enhance ED patient flow. It requires validation in an independent patient population before introduction into clinical practice.

International survey of emergency physicians' priorities for clinical decision rules.

OBJECTIVES: One of the first stages in the development of new clinical decision rules (CDRs) is determination of need. This study examined the clinical priorities of emergency physicians (EPs) working in Australasia, Canada, the United Kingdom, and the United States for the development of future CDRs. METHODS: The authors administered an e-mail and postal survey to members of the national emergency medicine (EM) associations in Australasia, Canada, the United Kingdom, and the United States. Results were analyzed via frequency distributions. RESULTS: The total response rate was 54.8% (1,150/2,100). The respondents were primarily male (74%), with a mean age of 42.5 years (SD +/- 8), and a mean of 12 years of experience (SD +/- 7). The top 10 clinical priorities (% selected) were: 1) investigation of febrile child < 36 months (62%); 2) identification of central or serious vertigo (42%); 3) lumbar puncture or admission of febrile child < 3 months (41%); 4) imaging for suspected transient ischemic attack (39%); 5) admission for anterior chest pain (37%); 6) computed tomography (CT) angiography for pulmonary embolus (30%); 7) admission for suicide risk (29%); 8) ultrasound for pain or bleeding in the first trimester of pregnancy (28%); 9) nonspecific weakness in elders (26%); and 10) CT for abdominal pain (25%). Between study countries, there was consistency in identification of clinical problems, but variation in prioritization. CONCLUSIONS: This international survey identified the sampled EPs' priorities for the future development of CDRs. The top priority overall was investigation of the febrile child < 36 months. These results will be valuable to researchers for future development of CDRs in EM that are relevant internationally.
