Interrater Reliability, Accuracy, and Triage Time Pre- and Post-implementation of a Real-Time Electronic Triage Decision-Support Tool.

STUDY OBJECTIVE: The electronic Canadian Triage and Acuity Scale (eCTAS) is a real-time electronic triage decision-support tool designed to improve patient safety and quality of care by standardizing the application of the Canadian Triage and Acuity Scale (CTAS). The objective of this study is to determine interrater agreement of triage scores pre- and post-implementation of eCTAS. METHODS: This was a prospective, observational study conducted in 7 emergency departments (EDs), selected to represent a mix of triage documentation practices, hospital types, and patient volumes. A provincial CTAS auditor observed triage nurses in the ED pre- and post-implementation of eCTAS and assigned an independent CTAS score in real time. Research assistants independently recorded triage time. Interrater agreement was estimated with κ statistics with 95% confidence intervals (CIs). RESULTS: A total of 1,491 individual triage assessments (752 pre-eCTAS, 739 post-implementation) were audited during 42 7-hour triage shifts (21 pre-eCTAS, 21 post-implementation). Exact modal agreement was achieved for 567 patients (75.4%) pre-eCTAS compared with 685 patients (92.7%) triaged with eCTAS. With the auditor's CTAS score as the reference, eCTAS significantly reduced the number of patients over-triaged (12.0% versus 5.1%; Δ 6.9; 95% CI 4.0 to 9.7) and under-triaged (12.6% versus 2.2%; Δ 10.4; 95% CI 7.9 to 13.2). Interrater agreement was higher with eCTAS (unweighted κ 0.89 versus 0.63; quadratic-weighted κ 0.93 versus 0.79). Median triage time was 312 seconds (n=3,808 patients) pre-eCTAS and 347 seconds (n=3,489 patients) with eCTAS (Δ 35 seconds; 95% CI 29 to 40 seconds). CONCLUSION: A standardized, electronic approach to performing triage assessments improves both interrater agreement and data accuracy without substantially increasing triage time.

Nursing duties and accreditation standards and their impacts: The nursing perspective.

BACKGROUND: Medical advances and increasingly complex patients presenting to the Emergency Department (ED) make nursing challenging. Gaining new knowledge and skills is a perpetual requirement. New quality initiatives to improve patient safety and care are being constantly introduced and create significant work and time pressures for healthcare providers involved. STUDY QUESTION: Do ED nurses support the introduction of new quality standards, in addition to their current heavy workload? STUDY DESIGN: A cross-sectional survey. METHODS: All ED nurses in the Edmonton zone were invited to complete a survey on nursing beliefs regarding various accreditation standards and their impacts. The survey was developed iteratively, involving study investigators, the Health Authority Management Team, and Nursing Managers. Response options included a 7-point Likert scale of agreement. Median ratings and interquartile ranges were determined for each survey statement. RESULTS: A total of 433/1241 (34.9%) surveys were completed. Respondents were RNs (91.4%), female (88.9%), with 0-5years ED experience (43.7%). Overall, respondents 'agreed' or 'strongly agreed' with the statements, indicating favourable attitudes towards Accreditation Canada standards and other quality initiatives. They were neutral towards universal domestic violence screening, and the differentiation between a Best Possible Medication History and medication reconciliation. CONCLUSIONS: Despite their heavy workload, nurses strongly agreed on the importance of medication reconciliation, falls risk, and skin care, but felt that improved documentation forms could support efficiency. This nursing perspective is valuable in informing attempts to standardize and simplify documentation, including the design and implementation of a provincial clinical information system.

Factors influencing time to computed tomography in emergency department patients with suspected subarachnoid haemorrhage.

BACKGROUND: CT has excellent sensitivity for subarachnoid haemorrhage (SAH) when performed within 6 hours of headache onset, but it is unknown to what extent patients with more severe disease are likely to undergo earlier CT, potentially inflating estimates of sensitivity. Our objective was to evaluate which patient and hospital factors were associated with earlier neuroimaging in alert, neurologically intact ED patients with suspected SAH. METHODS: We analysed data from two large sequential prospective cohorts of ED patients with acute headache undergoing CT for suspected SAH. We examined the time interval from headache onset to CT, both overall and subdivided from headache onset to hospital registration and from registration to CT. RESULTS: Among 2412 patients with headache, 194 had SAH, with 178 identified on unenhanced CT. Of these, 91 (51.1%) were identified by CT within 6 hours of headache onset and 87 after 6 hours. Patients with SAH had a shorter time from headache onset to hospital presentation (median 4.5 hours, IQR 1.7-22.7 vs 9.6 hours, IQR 2.8-46.0, p<0.001) and were imaged sooner after headache onset (6.4 hours, IQR 3.5-27.1 vs 12.6 hours, IQR 5.5-48.0, p<0.001) compared with those without SAH. The median time from in-hospital registration to CT scan was significantly shorter in those patients with SAH although this difference was less than 1 hour (1.9 hours, IQR 1.2-2.8 vs 2.5 hours, IQR 1.5-3.9, p<0.001). Arrival by ambulance (OR 3.1, 95% CI 1.94 to 4.98, p<0.001) and higher acuity at triage (OR 1.39, 95% CI 1.02 to 1.88, p=0.032) were among the factors associated with having CT imaging within 6 hours of headache onset. CONCLUSIONS: Time from headache onset to imaging is moderately associated with positive imaging for SAH. Delay to hospital presentation accounts for the largest fraction of time to imaging, especially those without SAH. These findings suggest limited opportunity to reduce lumbar puncture rates simply by accelerating in-hospital processes when imaging delays are under 2 hours, as diagnostic yield of imaging decreases beyond the 6-hour imaging window from headache onset.

Pilot study comparing sepsis management with and without electronic clinical practice guidelines in an academic emergency department.

BACKGROUND: Sepsis is a potentially life-threatening condition that requires urgent management in an Emergency Department (ED). Evidence-based guidelines for managing sepsis have been developed; however, their integration into routine practice is often incomplete. Care maps may help clinicians meet guideline targets more often. OBJECTIVES: To determine if electronic clinical practice guidelines (eCPGs) improve management of patients with severe sepsis and septic shock (SS/SS). METHODS: The impact of an eCPG on the management of patients presenting with SS/SS over a 3-year period at a tertiary care ED was evaluated using retrospective case-control design and chart review methods. Cases and controls, matched by age and sex, were chosen from an electronic database using physician sepsis diagnoses. Data were compared using McNemar tests or paired t-tests, as appropriate. RESULTS: Overall, 51 cases and controls were evaluated; the average age was 62 years, and 60% were male. eCPG patients were more likely to have a central venous pressure and central venous oxygen saturation measured; however, lactate measurement, blood cultures, and other investigations were similarly ordered (all p > 0.05). The administration of antibiotics within 3 h (63% vs. 41%; p = 0.03) and vasopressors (45% vs. 20%; p = 0.02) was more common in the eCPG group; however, use of corticosteroids and other interventions did not differ between the groups. Overall, survival was high and similar between groups. CONCLUSION: A sepsis eCPG experienced variable use; however, physicians using the eCPG achieved more quality-of-care targets for SS/SS. Strategies to increase the utilization of eCPGs in Emergency Medicine seem warranted.

Clinical decision rules to rule out subarachnoid hemorrhage for acute headache.

IMPORTANCE: Three clinical decision rules were previously derived to identify patients with headache requiring investigations to rule out subarachnoid hemorrhage. OBJECTIVE: To assess the accuracy, reliability, acceptability, and potential refinement (ie, to improve sensitivity or specificity) of these rules in a new cohort of patients with headache. DESIGN, SETTING, AND PATIENTS: Multicenter cohort study conducted at 10 university-affiliated Canadian tertiary care emergency departments from April 2006 to July 2010. Enrolled patients were 2131 adults with a headache peaking within 1 hour and no neurologic deficits. Physicians completed data forms after assessing eligible patients prior to investigations. MAIN OUTCOMES AND MEASURES: Subarachnoid hemorrhage, defined as (1) subarachnoid blood on computed tomography scan; (2) xanthochromia in cerebrospinal fluid; or (3) red blood cells in the final tube of cerebrospinal fluid, with positive angiography findings. RESULTS: Of the 2131 enrolled patients, 132 (6.2%) had subarachnoid hemorrhage. The decision rule including any of age 40 years or older, neck pain or stiffness, witnessed loss of consciousness, or onset during exertion had 98.5% (95% CI, 94.6%-99.6%) sensitivity and 27.5% (95% CI, 25.6%-29.5%) specificity for subarachnoid hemorrhage. Adding "thunderclap headache" (ie, instantly peaking pain) and "limited neck flexion on examination" resulted in the Ottawa SAH Rule, with 100% (95% CI, 97.2%-100.0%) sensitivity and 15.3% (95% CI, 13.8%-16.9%) specificity. CONCLUSIONS AND RELEVANCE: Among patients presenting to the emergency department with acute nontraumatic headache that reached maximal intensity within 1 hour and who had normal neurologic examination findings, the Ottawa SAH Rule was highly sensitive for identifying subarachnoid hemorrhage. These findings apply only to patients with these specific clinical characteristics and require additional evaluation in implementation studies before the rule is applied in routine clinical care.

Febrile neutropenia in EDs: the role of an electronic clinical practice guideline.

PURPOSE: Evidence-based clinical practice guidelines (CPGs) for managing febrile neutropenia (FN) are widely available; however, the integration of guidelines into routine practice is often incomplete. This study evaluated the uptake and clinical impact of implementing an electronic CPG on the management and outcomes of patients presenting with FN at 4 urban emergency departments (ED). METHODS: A retrospective chart review over a 3-year period at 4 hospitals in Edmonton, Alberta, was performed. Potentially eligible patient visits were identified by searching the Ambulatory Care Classification System database using International Classification of Diseases, 10th Edition, codes and ED physician diagnoses of FN. ED patients with fever (>38°C at home or in ED) and neutropenia (white blood cell count of <1000 cells/mm(3) or a neutrophil count of <500 cells/mm(3)) who received an ED diagnosis of FN were included. RESULTS: From 371 potential cases, 201 unique cases of FN were included. Overall, the electronic CPG was used in 76 (37.8%) of 201 patient visits; however, there were significant differences in CPG utilization between hospitals. Clinical practice guideline usage was greatest at the University of Alberta Hospital (57%). This finding correlated with a decrease in time from triage to first antibiotic by 1 hour compared to the 3 control hospitals (3.9 vs 4.9 hours, P = .022). CONCLUSIONS: The electronic CPG is a useful clinical tool that can improve patient management in the ED, and strategies to increase its utilization in this and other regions should be pursued.

The role of full capacity protocols on mitigating overcrowding in EDs.

OBJECTIVE: Overcrowding is an important issue facing many emergency departments (EDs). Access block (admitted patients occupying ED stretchers) is a leading contributor, and expeditious placement of admitted patients is an area of research interest. This review examined the effectiveness of full capacity protocols (FCPs) on mitigating ED overcrowding. METHODS: A comprehensive literature search was undertaken to identify potentially relevant studies between 1966 and 2009. Intervention studies in which an FCP was used to influence ED/hospital length of stay and ED/hospital access block were included as a single program or part of a systemwide intervention. Two reviewers independently assessed citation relevance, inclusion, study quality, and extracted data; because of limited data, pooling was not undertaken. RESULTS: From 14 446 potentially relevant studies, 2 abstracts from the same comparative study were included. From 29 studies on systemwide intervention, 4 contained an FCP component. The included study was a single-center ED study using a before-after design; its methodological quality was rated as weak. One of the abstracts reported that an FCP was associated with less ED length of stay (5-hour reduction) when compared with the comparison period; the other reported that an FCP decreased ED and hospital access block (28% and 37% reduction, respectively). The ED triggers, format, and implementation of FCP protocols varied widely. CONCLUSION: Although FCPs may be a promising alternative for overcrowded EDs, the available evidence upon which to support implementation of an FCP is limited. Additional efforts are required to improve the outcome reporting of FCP research using high-quality research methods.

The role of a rapid assessment zone/pod on reducing overcrowding in emergency departments: a systematic review.

OBJECTIVE: To evaluate the effectiveness of a rapid assessment zone (RAZ) to mitigate emergency department (ED) overcrowding. METHODS: Electronic databases, controlled trial registries, conference proceedings, study references, experts in the field and correspondence with authors were used to identify potentially relevant studies. Intervention studies, in which a RAZ was used to influence length of stay, physician initial assessment and patients left without being seen, were included. Mean differences were calculated and reported with corresponding 95% CIs; individual statistics are presented as RR with associated 95% CI. RESULTS: From 14 446 potentially relevant studies, four studies were included in the review. The quality of one study was appraised as moderately high; others were rated as weak. Two studies showed that a RAZ was associated with a reduction of 20 min (95% CI: -47.2 to 7.2) in the ED length of stay; in one non-randomised clinical trial (RCT), a 192 min reduction was reported (95% CI: -211.6 to -172.4). Physician initial assessment showed a reduction of 8.0 min; 95% CI: -13.8 to -2.2 in the RCT and a reduction of 33 min (95% CI: -42.3 to -23.6) and 18 min (95% CI: -22.2 to -13.8) respectively were found in two non-RCTs. There was a reduction in the risk of patient leaving without being seen (RCT: RR=0.93, 95% CI: 0.77 to 1.12; non-RCT: RR =0.68, 95% CI: 0.63 to 0.73). CONCLUSIONS: Although the results are consistent, and low acuity patients seem to benefit the most from a RAZ, the available evidence to support its implementation is limited.

Delphi consensus on the feasibility of translating the ACEP clinical policies into computerized clinical decision support.

Clinical practice guidelines are developed to reduce variations in clinical practice, with the goal of improving health care quality and cost. However, evidence-based practice guidelines face barriers to dissemination, implementation, usability, integration into practice, and use. The American College of Emergency Physicians (ACEP) clinical policies have been shown to be safe and effective and are even cited by other specialties. In spite of the benefits of the ACEP clinical policies, implementation of these clinical practice guidelines into physician practice continues to be a challenge. Translation of the ACEP clinical policies into real-time computerized clinical decision support systems could help address these barriers and improve clinician decision making at the point of care. The investigators convened an emergency medicine informatics expert panel and used a Delphi consensus process to assess the feasibility of translating the current ACEP clinical policies into clinical decision support content. This resulting consensus document will serve to identify limitations to implementation of the existing ACEP Clinical Policies so that future clinical practice guideline development will consider implementation into clinical decision support at all stages of guideline development.

Comparison between Canadian Triage and Acuity Scale and Taiwan Triage System in emergency departments.

BACKGROUND/PURPOSE: Since the implementation of National Health Insurance in Taiwan, Emergency Department (ED) volume has progressively increased, and the current triage system is insufficient and needs modification. This study compared the prioritization and resource utilization differences between the four-level Taiwan Triage System (TTS) and the standardized five-level Canadian Triage and Acuity Scale (CTAS) among ED patients. METHODS: This was a prospective observational study. All adult ED patients who presented to three different medical centers during the study period were included. Patients were independently triaged by the duty triage nurse using TTS, and a single trained research nurse using CTAS with a computer support software system. Hospitalization, length of stay (LOS), and medical resource consumption were analyzed by comparing TTS and CTAS by acuity levels. RESULTS: There was significant disparity in patient prioritization between TTS and CTAS among the 1851 enrolled patients. With TTS, 7.8%, 46.1%, 45.9% and 0.2% were assigned to levels 1, 2, 3, and 4, respectively. With CTAS, 3.5%, 24.4%, 44.3%, 22.4% and 5.5% were assigned to levels 1, 2, 3, 4, and 5, respectively. The hospitalization rate, LOS, and medical resource consumption differed significantly between the two triage systems and correlated better with CTAS. CONCLUSION: CTAS provided better discrimination for ED patient triage, and also showed greater validity when predicting hospitalization, LOS, and medical resource consumption. An accurate five-level triage scale appeared superior in predicting patient acuity and resource utilization.

Consistency of triage scores by presenting complaint pre- and post-implementation of a real-time electronic triage decision support tool.

OBJECTIVE: eCTAS is a real-time electronic decision-support tool designed to standardize the application of the Canadian Triage and Acuity Scale (CTAS). This study addresses the variability of CTAS score distributions across institutions pre- and post-eCTAS implementation. METHODS: We used population-based administrative data from 2016-2018 from all emergency departments (EDs) that had implemented eCTAS for 9 months. Following a 3-month stabilization period, we compared 6 months post-eCTAS data to the same 6 months the previous year (pre-eCTAS). We included triage encounters of adult (≥17 years) patients who presented with 1 of 16 pre-specified, high-volume complaints. For each ED, consistency was calculated as the absolute difference in CTAS distribution compared to the average of all included EDs for each presenting complaint. Pre-eCTAS and post-eCTAS change scores were compared using a paired-samples t-test. We also assessed if eCTAS modifiers were associated with triage consistency. RESULTS: There were 363,214 (183,231 pre-eCTAS, 179,983 post-eCTAS) triage encounters included from 35 EDs. Triage scores were more consistent (P < 0.05) post-eCTAS for 6 (37.5%) presenting complaints: chest pain (cardiac features), extremity weakness/symptoms of cerebrovascular accident, fever, shortness of breath, syncope, and hyperglycemia. Triage consistency was similar pre- and post-eCTAS for altered level of consciousness, anxiety/situational crisis, confusion, depression/suicidal/deliberate self-harm, general weakness, head injury, palpitations, seizure, substance misuse/intoxication, and vertigo. Use of eCTAS modifiers was associated with increased triage consistency. CONCLUSIONS: eCTAS increased triage consistency across many, but not all, high-volume presenting complaints. Modifier use was associated with increased triage consistency, particularly for non-specific complaints such as fever and general weakness.

Tracking emergency department overcrowding in a tertiary care academic institution.

Despite the release of a national report describing key markers of emergency department (ED) overcrowding, limited linear data using these markers have been published. We sought to report the degree and trends of ED overcrowding in a typical academic hospital and to highlight some of the key markers of ED patient flow and care. We conducted a prospective study in a large Canadian urban tertiary care teaching hospital that receives approximately 55,000 annual adult ED visits. A database captured demographic and real-time process of care data for each patient from 2000 to 2007. Descriptive data are reported using Canadian Triage and Acuity Scale (CTAS) scores. Over the study period, the ED patient visit volume and presentation times remained predictable. Emergent cases (CTAS levels 1-2) doubled from 8 to 16.6%, and urgent cases (CTAS level 3) increased from 40.2 to 50.3%. Moreover, semi-urgent presentations (CTAS level 4) decreased from 42.4 to 28.8%, and non-urgent cases (CTAS level 5) dropped from 9.4 to 4.3%. The median wait time from triage to bed location increased from two minutes (inter-quartile range [IQR] 1, 46) in 2000 to 27 minutes (IQR 2, 110) in 2007, while the median time from bed location to physician remained constant (29 minutes in 2001 versus 28 minutes in 2007). Overall, admissions increased from 20.4 to 23%. Semi-urgent and non-urgent admissions dropped from 11.5 to 7.4% and 3.2 to 1.8%, respectively. Admitted patients "boarding" in the ED increased from 70,955 hours in 2002 to 118,741 hours in 2007, while the number of emergent and urgent patients leaving without being seen increased by more than 400%. ED overcrowding in a tertiary care hospital is primarily a result of access block due to boarding admitted patients, a situation that poses serious risks to the majority of patients who have emergent or urgent conditions that cannot be managed appropriately in the waiting room.

Consultations in the emergency department: a systematic review of the literature.

OBJECTIVES: Consultation is a common and important aspect of emergency department (ED) practice which can lead to delays in patient flow. Little is known about ED consultations and this review systematically evaluated the literature on ED consultations. METHODS: Comprehensive searches of MEDLINE, PUBMED, SCIRUS, Cochrane Library, Web of Science, Health Star and other databases from 1966 to 2007 were performed. The grey literature and reference lists were searched and authors were contacted to identify other eligible studies. Published and unpublished studies reporting the proportion of consultations in the ED using any type of design were considered for this review. Eligible studies were required to involve patients presenting to the ED. Studies reporting on the proportion of consultation in a specific subpopulation of patients and interventions to improve consultations were also considered for inclusion. Two reviewers independently selected studies and extracted data from included studies regarding the proportion of consultations in the ED or the patient subgroup. Individual study proportions were calculated together with 95% confidence intervals (CI). RESULTS: From more than 15,000 pre-screened citations, 12 studies were finally included in the review. All but three of the included studies were published. Overall, four studies examined ED consultation proportions, six identified the rate of consultation for special populations of ED presentations and two examined interventions to improve consultations. Consultation varied from 20% to 40% for all patients, with lower proportions in the selected populations studied and a high rate of hospitalisation for consulted patients. Limited research on interventions to improve the ED consultation process has also been completed. CONCLUSIONS: Consultation research in the emergency setting is limited and variable; however, high consultation rates exist in some centres. This systematic review outlines the current state of the literature and suggests that further research is urgently needed.

Simulation of a hospital disaster plan: a virtual, live exercise.

INTRODUCTION: Currently, there is no widely available method to evaluate an emergency department disaster plan. Creation of a standardized patient database and the use of a virtual, live exercise may lead to a standardized and reproducible method that can be used to evaluate a disaster plan. PURPOSE: A virtual, live exercise was designed with the primary objective of evaluating a hospital's emergency department disaster plan. Education and training of participants was a secondary goal. METHODS: A database (disastermed.ca) of histories, physical examination findings, and laboratory results for 136 simulated patients was created using information derived from actual patient encounters. The patient database was used to perform a virtual, live exercise using a training version of the emergency department's information system software. RESULTS: Several solutions to increase patient flow were demonstrated during the exercise. Conducting the exercise helped identify several faults in the hospital disaster plan, including outlining the important rate-limiting step. In addition, a significant degree of under-triage was demonstrated. Estimates of multiple markers of patient flow were identified and compared to Canadian guidelines. Most participants reported that the exercise was a valuable learning experience. CONCLUSIONS: A virtual, live exercise using the disastermed.ca patient database was an inexpensive method to evaluate the emergency department disaster plan. This included discovery of new approaches to managing patients, delineating the rate-limiting steps, and evaluating triage accuracy. Use of the patient timestamps has potential as a standardized international benchmark of hospital disaster plan efficacy. Participant satisfaction was high.

Consultation outcomes in the emergency department: exploring rates and complexity.

OBJECTIVE: Consultation is a common and important aspect of emergency department (ED) care. We prospectively examined the consultation rates, the admission rates of consulted patients, the emergency physician (EP) disposition prediction of consulted patients and the difficult consultations rates in 2 tertiary care hospitals. METHODS: Attending EPs recorded consultations during 5 randomly selected shifts over an 8-week period using standardized forms. Subsequent computer outcome data were extracted for each patient encounter, as well as demographic data from the ED during days in which there was a study shift. RESULTS: During 105 clinical shifts, 1930 patients were managed by 21 EPs (median 17 patients per shift; interquartile range 14-23). Overall, at least 1 consultation was requested in 38% of patients. More than one-half of the patients (54.3%) who received a consultation were admitted to the hospital. Consultation proportions were similar between males and females (51% v. 49%, p=0.03). Consultations occurred more frequently for patients who were older, had higher acuity presentations, arrived during daytime hours or arrived by ambulance. The proportion of agreement between the EP's and consultant's opinion on the need for admission was 89% (kappa=0.77, 95% confidence interval 0.72-0.83). Overall, 92% of patents received 1 consultation. Six percent of the consultations were perceived as "difficult" by the EPs (defined as the EP's subjective impression of difficulties with consultation times, accessibility and availability of consultants, and the interaction with consultants or disposition issues). CONCLUSION: Consultation is a common process in the ED. It often results in admission and is predictable based on simple patient factors. Because of perceived difficulty with consultations, strategies to improve the EP consultation process in the ED seem warranted.

Emergency Physician Use of the Alberta Netcare Portal, a Province-Wide Interoperable Electronic Health Record: Multi-Method Observational Study.

BACKGROUND: The adoption and use of an electronic health record (EHR) can facilitate real-time access to key health information and support improved outcomes. Many Canadian provinces use interoperable EHRs (iEHRs) to facilitate health information exchange, but the clinical use and utility of iEHRs has not been well described. OBJECTIVE: The aim of this study was to describe the use of a provincial iEHR known as the Alberta Netcare Portal (ANP) in 4 urban Alberta emergency departments. The secondary objectives were to characterize the time spent using the respective electronic tools and identify the aspects that were perceived as most useful by emergency department physicians. METHODS: In this study, we have included 4 emergency departments, 2 using paper-based ordering (University of Alberta Hospital [UAH] and Grey Nuns Community Hospital [GNCH]) and 2 using a commercial vendor clinical information system (Peter Lougheed Centre [PLC] and Foothills Medical Centre [FMC]). Structured clinical observations of ANP use and system audit logs analysis were compared at the 4 sites from October 2014 to March 2016. RESULTS: Observers followed 142 physicians for a total of 566 hours over 376 occasions. The median percentage of observed time spent using ANP was 8.5% at UAH (interquartile range, IQR, 3.7%-13.3%), 4.4% at GNCH (IQR 2.4%-4.4%), 4.6% at FMC (IQR 2.4%-7.6%), and 5.1% at PLC (IQR 3.0%-7.7%). By combining administrative and access audit data, the median number of ANP screens (ie, results and reports displayed on a screen) accessed per patient visit were 20 at UAH (IQR 6-67), 9 at GNCH (IQR 4-29), 7 at FMC (IQR 2-18), and 5 at PLC (IQR 2-14). When compared with the structured clinical observations, the statistical analysis of screen access data showed that ANP was used more at UAH than the other sites. CONCLUSIONS: This study shows that the iEHR is well utilized at the 4 sites studied, and the usage patterns implied clinical value. Use of the ANP was highest in a paper-based academic center and lower in the centers using a commercial emergency department clinical information system. More study about the clinical impacts of using iEHRs in the Canadian context including longer term impacts on quality of practice and safety are required.

The effect of training on nurse agreement using an electronic triage system.

OBJECTIVES: Emergency department (ED) triage prioritizes patients based on urgency of care, and the Canadian Triage and Acuity Scale (CTAS) is the national standard. We describe the inter-rater agreement and manual overrides of nurses using a CTAS-compliant web-based triage tool (eTRIAGE) for 2 different intensities of staff training. METHODS: This prospective study was conducted in an urban tertiary care ED. In phase 1, eTRIAGE was deployed after a 3-hour training course for 24 triage nurses who were asked to share this knowledge during regular triage shifts with colleagues who had not received training (n = 77). In phase 2, a targeted group of 8 triage nurses underwent further training with eTRIAGE. In each phase, patients were assessed first by the duty triage nurse and then by a blinded independent study nurse, both using eTRIAGE. Inter-rater agreement was calculated using kappa (weighted kappa) statistics. RESULTS: In phase 1, 569 patients were enrolled with 513 (90.2%) complete records; 577 patients were enrolled in phase 2 with 555 (96.2%) complete records. Inter-rater agreement during phase 1 was moderate (weighted kappa = 0.55; 95% confidence interval [CI] 0.49-0.62); agreement improved in phase 2 (weighted kappa = 0.65; 95% CI 0.60-0.70). Manual overrides of eTRIAGE scores were infrequent (approximately 10%) during both periods. CONCLUSIONS: Agreement between study nurses and duty triage nurses, both using eTRIAGE, was moderate to good, with a trend toward improvement with additional training. Triage overrides were infrequent. Continued attempts to refine the triage process and training appear warranted.

Frequency, determinants and impact of overcrowding in emergency departments in Canada: a national survey.

Several reports have documented the prevalence and severity of emergency department (ED) overcrowding at specific hospitals or cities in Canada; however, no study has examined the issue at a national level. A 54-item, self-administered, postal and web-based questionnaire was distributed to 243 ED directors in Canada to collect data on the frequency, impact and factors associated with ED overcrowding. The survey was completed by 158 (65% response rate) ED directors, 62% of whom reported overcrowding as a major or severe problem during the past year. Directors attributed overcrowding to a variety of issues including a lack of admitting beds (85%), lack of acute care beds (74%) and the increased length of stay of admitted patients in the ED (63%). They perceived ED overcrowding to have a major impact on increasing stress among nurses (82%), ED wait times (79%) and the boarding of admitted patients in the ED while waiting for beds (67%). Overcrowding is not limited to large urban centres; nor is it limited to academic and teaching hospitals. The perspective of ED directors reinforces the need for further examination of effective policies and interventions to reduce ED overcrowding.

Prehospital Application of the Canadian Triage and Acuity Scale by Emergency Medical Services.

OBJECTIVES: Triage is fundamental to emergency patient assessment. Effective triage systems accurately prioritize patients and help predict resource utilization. CTAS is a validated five-level triage score utilized in Emergency Departments (EDs) across Canada and internationally. Historically CTAS has been applied by triage nurses in EDs. Observational evidence suggests that the CTAS might be implemented reliably by paramedics in the prehospital setting. This is the first system-wide assessment of CTAS interrater reliability between paramedics and triage nurses during clinical practice. METHODS: Variables were extracted from hospital and EMS databases. EMS providers determined CTAS on-scene, CTAS pre-transport, and CTAS on-arrival at hospital for each patient (N=14,378). The hospital arrival EMS CTAS (CTAS arrival ) score was compared to the initial nursing CTAS score (CTAS initial ) and the final nursing CTAS score (CTAS final ) incuding nursing overrides. Interrater reliability between ED CTAS initial and EMS CTAS arrival scores was assessed. Interrater reliability between ED CTAS final and EMS CTAS arrival scores, as well as proportion of patient encounters with perfect or near-perfect agreement, were evaluated. RESULTS: Our primary outcome, interrater reliability [kappa=0.437 (p<0.001, 95% CI 0.421-0.452)], indicated moderate agreement. EMS CTAS arrival and ED CTAS initial scores had an exact or within one point match 84.3% of the time. The secondary interrater reliability outcome between hospital arrival EMS CTAS (CTAS arrival ) score and the final ED triage CTAS score (CTAS final ) showed moderate agreement with kappa =0.452 (p<0.001, 95% CI 0.437-0.466). CONCLUSIONS: Interrater reliability of CTAS scoring between triage nurses and paramedics was moderate in this system-wide implementation study.

Data collection on patients in emergency departments in Canada.

OBJECTIVE: Relatively little is known about the ability of Canadian emergency departments (EDs) and the federal, provincial and territorial governments to quantify ED activity. The objectives of this study were to determine the use of electronic patient data in Canadian EDs, the accessibility of provincial data on ED visits, and to identify the data elements and current methods of ED information system (EDIS) data collection nationally. METHODS: Surveys were conducted of the following 3 groups: 1) all ED directors of Canadian hospitals located in communities of >10,000 people, 2) all electronic EDIS vendors, and 3) representatives from the ministries of health from 13 provincial and territorial jurisdictions who had knowledge of ED data collection. RESULTS: Of the 243 ED directors contacted, 158 completed the survey (65% response rate) and 39% of those reported using an electronic EDIS. All 11 EDIS vendor representatives responded. Most of the vendors provide a similar package of basic EDIS options, with add-on features. All 13 provincial or territorial government representatives completed the survey. Nine (69%) provinces and territories collect ED data, however the source of this information varies. Five provinces and territories collect triage data, and 3 have a comprehensive, jurisdiction-wide, population-based ED database. Thirty-nine percent of EDs in larger Canadian communities track patients using electronic methods. A variety of EDIS vendor options are available and used in Canada. CONCLUSION: The wide variation in methods and in data collected presents serious barriers to meaningful comparison of ED services across the country. It is little wonder that the majority of information regarding ED overcrowding in Canada is anecdotal, when the collection of this critical health information is so variable. There is an urgent need to place the collection of ED information on the provincial and national agenda and to ensure that the collection of this information consistent, comprehensive and mandatory.
