Revisions to the Canadian Emergency Department Triage and Acuity Scale Implementation Guidelines

Acuity Assessment in Obstetrical Triage

OBJECTIVE

A five-category Obstetrical Triage Acuity Scale (OTAS) was developed with a comprehensive set of obstetrical determinants. The purposes of this study were: (1) to compare the inter-rater reliability (IRR) in tertiary and community hospital settings and measure the intra-rater reliability (ITR) of OTAS; (2) to establish the validity of OTAS; and (3) to present the first revision of OTAS from the National Obstetrical Triage Working Group.

METHODS

To assess IRR, obstetrical triage nurses were randomly selected from London Health Sciences Centre (LHSC) (n = 8), Stratford General Hospital (n = 11), and Chatham General Hospital (n= 7) to assign acuity levels to clinical scenarios based on actual patient visits. At LHSC, a group of nurses were retested at nine months to measure ITR. To assess validity, OTAS acuity level was correlated with measures of resource utilization.

RESULTS

OTAS has significant and comparable IRR in a tertiary care hospital and in two community hospitals. Repeat assessment in a cohort of nurses demonstrated significant ITR. Acuity level correlated significantly with performance of routine and second order laboratory investigations, point of care ultrasound, nursing work load, and health care provider attendance. A National Obstetrical Triage Working Group was formed and guided the first revision. Four acuity modifiers were added based on hemodynamics, respiratory distress, cervical dilatation, and fetal well-being.

CONCLUSION

OTAS is the first obstetrical triage scale with established reliability and validity. OTAS enables standardized assessments of acuity within and across institutions. Further, it facilitates assessment of patient care and flow based on acuity.

Reliability of the Canadian Triage and Acuity Scale: interrater and intrarater agreement from a community and an academic emergency department

OBJECTIVES

The Canadian Triage and Acuity Scale (CTAS) is a five-level triage tool that is used to help prioritize the order in which emergency department (ED) patients should be seen. The objectives of this study were to determine the interrater and intrarater agreement of the 2008 CTAS guideline revisions by triage nurses and to compare agreement between triage nurses working in a small community ED and an academic ED.

METHODS

Seventy-eight triage nurses assigned CTAS scores and free-text presenting complaints for 10 paper-based case scenarios. For five scenarios, the CTAS score should have remained unchanged from previous guidelines, whereas the other five scenarios should have been triaged differently based on the 2008 CTAS first-order modifiers. Thirty-three participants repeated the questionnaire 90 days later, and intrarater agreement was measured.

RESULTS

There was a higher level of agreement (κ  =  0.73; 95% CI 0.68-0.79) for the five case scenarios, which relied on the older 2004 guidelines compared to the scenarios where the 2008 guidelines would have suggested a different triage level (κ  =  0.50; 95% CI 0.42-0.59). For the 10 case scenarios analyzed, the free-text presenting complaints matched the Canadian Emergency Department Information System (CEDIS) list 90.1% of the time (κ  =  0.80; 95% CI 0.76-0.84).

CONCLUSION

The reliability of CTAS scoring by academic and community ED nurses was relatively good; however, the application of the 2008 CTAS revisions appears less reliable than the 2004 CTAS guidelines. These results may be useful to develop educational materials to strengthen reliability and validity for triage scoring using the 2008 CTAS guideline revisions.

The Impact of Standardized Acuity Assessment and a Fast-Track on Length of Stay in Obstetric Triage: A Quality Improvement Study

To prospectively assess the impact of a standardized 5-category Obstetrical Triage Acuity Scale (OTAS) and a fast-track for lower-acuity patients on patient flow. Length of stay (LOS) data of women presenting to obstetric triage were abstracted from the electronic medical record prior to (July 1, 2011, to March 30, 2012) and following OTAS implementation (April 1 to December 31, 2012). Following computerized simulation modeling, a fast-track for lower acuity women was implemented (January 1, 2013, to February 28, 2014). Prior to OTAS implementation (8085 visits), the median LOS was 105 (interquartile range [IQR] = 52-178) minutes. Following OTAS implementation (8131 visits), the median LOS decreased to 101 (IQR = 49-175) minutes (P = .04). The LOS did not correlate well with acuity. Simulation modeling predicted that a fast-track for OTAS 4 and 5 patients would reduce the LOS. The LOS for lower-acuity patients in the fast-track decreased to 73 (IQR = 40-140) minutes (P = .005). In addition, the overall LOS (12 576 visits) decreased to 98 (IQR = 47-172) minutes (6.9% reduction; P < .001). Standardized assessment of acuity and a fast-track for lower acuity pregnant women decreased the overall LOS and the LOS of lower-acuity patients.

Reliability of Canadian Emergency Department Triage and Acuity Scale (CTAS) in Saudi Arabia

Background

The Canadian Emergency Department Triage and Acuity Scale (CTAS) is an integral part of the Canadian emergency medicine triaging system. There is growing interest and implementation of CTAS worldwide. However, little is known about its reliability outside Canada. The aim of this study was to determine the reliability agreement of CTAS in a tertiary care emergency center in Saudi Arabia.

Methods

Ten triage nurses (five senior and five junior nurses) utilized CTAS guidelines to independently assign a triage level for 160 real case-based scenarios. Quadratic weighted kappa statistics were used to measure raters’ agreements.

Results

Raters provided 1600 triage category assignments to case scenarios for analysis. Intra-rater agreement was similar for both senior and junior nurses; for senior nurses (SN1) kappa 0.871 95 % CI (0.840–0.897), and for junior nurses (SN2) kappa 0.871 95 % CI (0.839–0.898). Inter-rater agreement for the SN1 versus SN2 nurses had statistically meaningful agreement across different triage levels (weighted kappa = 0.770) 95 % CI (0.742–0.797).

Conclusions

CTAS has good reliability among emergency department (ED) triage nurses in King Abdulaziz Medical City (KAMC), Saudi Arabia. The findings suggest that CTAS might be a reliable instrument when applied in countries outside Canada.

Implementation of an automated, real-time public health surveillance system linking emergency departments and health units: rationale and methodology

In September 2004, Kingston, Frontenac, Lennox and Addington (KFL&amp;A) Public Health, in collaboration with the Public Health Division of the Ontario Ministry of Health and Long-Term Care, Queen's University, the Public Health Agency of Canada, Kingston General Hospital and Hotel Dieu Hospital, began a 2-year pilot project to implement and evaluate an emergency department (ED) chief complaint syndromic surveillance system. Our objective was to evaluate a comprehensive and readily deployable real-time regional syndromic surveillance program and to determine its ability to detect gastrointestinal or respiratory outbreaks well in advance of traditional reporting systems. In order to implement the system, modifications were made to the University of Pittsburgh's Real-time Outbreak and Disease Surveillance (RODS) system, which has been successfully integrated into public health systems, and has enhanced communication and collaboration between them and EDs. This paper provides an overview of a RODS-based syndromic surveillance system as adapted for use at a public health unit in Kingston, Ontario. We summarize the technical specifications, privacy and security considerations, data capture, classification and management of the data streams, alerting and public health response. We hope that the modifications described here, including the addition of unique data streams, will provide a benchmark for future Canadian syndromic surveillance systems.

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 κ) 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 κ = 0.55; 95% confidence interval [CI] 0.49–0.62); agreement improved in phase 2 (weighted κ = 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.

What are kids getting into these days? A retrospective chart review of substance use presentations to a Canadian pediatric emergency department

OBJECTIVES

Goals for this study were to characterize the substances being used by youth who presented to an emergency department (ED), their demographic descriptors, and to describe the associated acute morbidity and mortality.

METHODS

We conducted a retrospective review of all youth, ages 10-16 years, who presented to a pediatric ED with complaints related to recreational drug use (n=641) for 2 years ending on December 31, 2009.

RESULTS

The median age of patients was 15 years; 56% were female. Six percent of patients were homeless, and 21% were wards of the state. The most frequent ingestions included ethanol (74%), marijuana (20%), ecstasy (19%), and medications (15%). Over one third of patients had ingested two or more substances. Ninety percent of patients were brought to the ED by the emergency medical services; 63% of these activations were by non-acquaintances. Of the 47% of youth who presented with a decreased level of consciousness, half had a Glasgow Coma Scale less than 13. The Canadian Triage and Acuity Scale score was 1 or 2 for 44% of patients. Sixty-eight percent received IV fluids, 42% received medication, and 4% were intubated. The admission rate was 9%.

CONCLUSIONS

Youth who presented to the ED for substance use represented a socially vulnerable population whose use of recreational substances resulted in high medical acuity and significant morbidity. Improved clinical identification of such high-risk youth and subsequent design of interventions to address problematic substance use and social issues are urgently needed to complement the acute medical care that youth receive.

Emergency department use by CTAS Levels IV and V patients

Introduction:

Many emergency department (ED) visits are non-urgent. Postulated reasons for these visits include lack of access to family physicians, convenience and 24/7 access, perceived need for investigations or treatment not available elsewhere, and as a mechanism for expedited referral to other specialists. We conducted a patient survey to determine why non-urgent patients use our tertiary care ED. Our primary objective was to determine how often the lack of a family physician was associated with non-urgent ED use.

Methods:

The survey was administered to Canadian Emergency Department Triage and Acuity Scale (CTAS) Level IV and V patients who attended the ED of the Queen Elizabeth II Health Sciences Centre in Halifax, NS, from March 7 to March 13, 2005.

Results:

Of the 352 eligible patients, 235 completed the survey (response rate, 67%). Fifty-six percent (132/235) had an acute medical problem of less than 48 hours, including 48% (114/235) with a recent injury. Thirty-four percent (82/235) had been referred to the ED, 49% (114/235) believed they required a specific service that was unavailable elsewhere (e.g., radiology, suturing, casting) and 43% (100/235) presented because of self-perceived urgency of their condition. Eighty-four percent (198/235) had a family physician; 23% (55/235) used the ED because of limited access to theirfamily physician and 3% (6/235) used the ED because they did not have a family physician.

Conclusions:

In this setting, most non-urgent ED visits involved patients who required a specific service offered by the ED, patients who believed their condition was urgent, or patients who were referred from the community to the ED. From a patient perspective, relatively few visits would be considered inappropriate. Lack of a family physician was not associated with non-urgent ED use; however, inability to obtain timely access to the FP was a factor in one-quarter of cases.

Health promotion and disease prevention in the emergency department: a feasibility study

Background:

Health promotion and disease prevention have been increasingly recognized as activities that may be within the scope of emergency medicine. The purpose of this feasibility study was to identify health risks and offer immediate interventions to adult patients who have drug and/or alcohol problems, incomplete immunization, are overdue for a Pap (Papanicolaou) smear, and/or are smokers.

Methods:

The study took place in a busy tertiary Emergency Department (ED) serving an inner-city population with a significant proportion of patients who are homeless, substance abusers, working poor, and/or recent immigrants. A convenience sample of patients completed a computer-based health-risk survey. Trained health promotion nurses offered appropriate interventions to patients following review and discussion of their self-reported data. Interventions included counseling for problem drinking, substance abuse, and smoking cessation, screening for cervical cancer, and immunization.

Results:

From October 20, 2000 to June 30, 2003, we enrolled 2366 patients. One thousand and eleven subjects (43%) reported substance abuse and 1095 (46%) were smokers. Of the 158 smokers contacted in follow-up, 19 (12%) had quit, 63 (40%) had reduced the number of cigarettes/day and 76 (48%) reported no change. Of 1248 women surveyed, 307 (25%) were overdue for a Pap smear and 54 (18%) received this intervention. Forty-four percent of subjects were overdue for at least one immunization and of those, 414 (40%) were immunized in the ED.

Conclusion:

At-risk patients can be identified using a computer-based screening tool, and appropriate interventions can be given to a proportion of these patients in a busy inner city ED without increasing wait time.

Variations in monetary distribution among Ontario’s Alternative Funding Agreement workload model hospitals

Objectives:

Alternative Funding Agreements (AFAs) were in place in 41 hospital emergency departments (EDs) in Ontario at the time of this survey (May to August 2005). Each of these 41 hospitals works with its own internal administrative model. The primary objective of this paper was to document the administrative models used in these Ontario EDs. The secondary objective was to inform current and future AFA EDs of the potential models.

Methods:

Telephone surveys were conducted with a member of each of the 41 AFA workload model hospitals.

Results:

All hospitals provided at least 1 emergency physician to answer the questionnaire. Although most AFA hospitals divide the AFA fund pool on an hourly basis, there is impressive variation on premium values awarded for day, evening, weekend and night shifts. Other variations included holdback of funds for bonuses, distribution of non-OHIP (Ontario Health Insurance Plan) dollars, on-call allowances, and different pay scales for the general practitioners and locums working in some departments.

Conclusions:

Allowing flexibility in distribution of AFA dollars to physicians in each group has helped make this program more acceptable. Many issues unrelated to funding remain to be resolved in order to stabilize ED recruitment and retention as well as improve work satisfaction. Further research on these latter topics is required to develop a fair and equitable funding arrangement that supports and enhances physician coverage in EDs across Canada.

Influence of publicly available online wait time data on emergency department choice in patients with noncritical complaints

Objectives:

Increased emergency department (ED) wait times lead to more patients who leave without being seen and decreased patient satisfaction. Many EDs post estimated wait times either online or in the ED to guide patient expectations. The objectives of this study were to assess patients' awareness of online wait time data and to investigate patients' willingness to use this information when choosing between two academic EDs in London, Ontario.

Methods:

A prospective study was conducted over a 2-month period in a tertiary ED with online available wait times. Patients over 18 years of age assigned a Canadian Triage and Acuity Scale (CTAS) score of 3, 4, or 5 were approached by trained research assistants to complete a 15-item paper-based questionnaire. Multivariable logistic regression models were used to determine factors independently associated with the outcomes.

Results:

A total of 1,211 patients completed the survey. Of these, 109 (9%) were aware that ED wait time information was available on the Internet; 544 (45%) reported that they would use the available data to make a decision on which ED to visit, and 536 (44%) indicated that they were more likely to go to the ED with a shorter wait time. Age, gender, household income, education, and Internet access were not associated with awareness of online ED wait times. Participants less than 40 years of age were more likely to use online wait time information.

Conclusion:

There is low awareness of the availability of ED wait time data published online in the study locaton. Future research may include the delivery of a public awareness strategy for ED wait time data and a re-evaluation of ED use and patient satisfaction following this.

Repeated emergency department visits among children admitted with meningitis or septicemia: a population-based study

STUDY OBJECTIVE

Early diagnosis of children with meningitis or septicemia remains a significant challenge in emergency medicine. We seek to describe the frequency of repeated emergency department (ED) visits among children admitted with meningitis or septicemia in Ontario, Canada.

METHODS

In this retrospective cohort study, using health administrative data, we included all children aged 30 days to 5 years who were hospitalized with a final diagnosis of meningitis or septicemia in Ontario between 2005 and 2010. ED visits at any hospital in the preceding 5 days were identified as potential repeated ED visits. We used generalized estimating equations to model the association of sex, age, triage score, immunocompromised state, visit timing, type of ED, and annual patient volume on the risk of repeated ED visits.

RESULTS

Of 521 children, 114 (21.9%) had repeated ED visits before admission. Children admitted on initial visit and those with repeated visits had similar median lengths of stay (13 versus 12 days), critical care use (21.1% versus 16.7%), and mortality (mean 2.9%). One in 3 children repeating visits returned to a different hospital. Repeated visits were associated with older age, a less acute triage score, and initial visit to a community hospital without available pediatric consultation.

CONCLUSION

In this cohort, repeated ED visits among children with meningitis or septicemia were common, yet they had health outcomes similar to those of children admitted on initial visit. One in 3 returned to a different ED, making it unlikely that EDs and clinicians can learn from these critical events without a regionalized reporting system.

Effect of the influenza virus rapid antigen test on a physician's decision to prescribe antibiotics and on patient length of stay in the emergency department

Background

Influenza virus infection is a common reason for visits to the emergency department (ED) during the influenza season. A rapid and accurate diagnosis of influenza virus infection is important to reduce unnecessary antibiotic prescription and to improve patient care. The aim of this study was to examine whether using the Influenza Virus Rapid Antigen Test (IVRAT) in the ED affects the decision to prescribe antibiotics or the length of hospital stay (LOS).

Methods

Data from patients suffering from an influenza-like illness (ILI) and who were discharged after visiting the ED at Chungbuk National University Hospital were reviewed over two influenza seasons: 2010–2011, when IVRAT was not used in the ED, and 2011–2012, when it was. The numbers of antibiotic prescriptions issued and the ED LOS during these two seasons were then compared.

Results

The number of antibiotic prescriptions was significantly lower in 2011–2012 (54/216, 25.0%) than in 2010–2011 (97/221, 43.9%; P<0.01). However, the median ED LOS for patients in 2011–2012 was much longer than that of patients in 2010–2011 (213 minutes vs. 257 minutes; P<0.01). During the 2011–2012 influenza season, 73 ILI patients showed a positive IVRAT result whereas 123 showed a negative result. Upon discharge, antibiotics were given to 42/123 (34.1%) ILI patients with a negative IVRAT result, but to only 7/73 (9.6%) patients with a positive IVRAT result (P<0.01).

Conclusions

Performing IVRAT in the ED reduced the prescription of antibiotics to ILI patients discharged after ED care. However, the ED LOS for patients who underwent IVRAT was longer than that for patients who did not. Thus, performing IVRAT in the ED reduces the unnecessary prescription of antibiotics to ILI patients during the influenza season.

Beat the clock! Wait times and the production of 'quality' in emergency departments

Emergency care in large urban hospitals across the country is in the midst of major redesign intended to deliver quality care through improved access, decreased wait times, and maximum efficiency. The central argument in this paper is that the conceptualization of quality including the documentary facts and figures produced to substantiate quality emergency care is socially organized within a powerful ruling discourse that inserts the interests of politics and economics into nurses' work. The Canadian Triage and Acuity Scale figures prominently in the analysis as a high-level organizer of triage work and knowledge production that underpins the way those who administer the system define, measure and evaluate emergency care processes, and then use this information for restructuring. Managerial targets and thinking not only dominate the way emergency work is understood, determined, and controlled but also subsume the actual work of health-care providers in spaces called 'wait times', where it is systematically rendered 'unknowable'. The analysis is supported with evidence from an extensive institutional ethnography that shows what nurses actually do to manage the safe passage of patients through their emergency care process starting with the work of triage nurses.

Reasons for non-urgent presentations to the emergency department in Saudi Arabia

BACKGROUND

The majority of patients who attend emergency departments (EDs) in Saudi Arabia have non-urgent problems, resulting in overcrowding, excessive waiting times and delayed care for more acutely ill patients. The purpose of this research was to examine the reasons for non-urgent visits to a Saudi ED and factors associated with patient perceptions of urgency.

METHODS

We administered a survey to 350 consecutively presenting Canadian Triage and Acuity Scale (CTAS) IV or V adult patients at a large tertiary ED in Riyadh region, Saudi Arabia, during 25 days of data collection in March 2013.

RESULTS

Over half of the sample usually visited the ED to access healthcare. The most common reasons for attending the ED were not having a regular healthcare provider (63%), being able to receive care on the same day (62%), and the convenience of and access to medical care 24/7 (62%). Approximately two-thirds of CTAS V patients and one-third of CTAS IV patients believed their conditions were more urgent than their triage nurse rating.

CONCLUSION

Multiple factors influence non-urgent visits to the ED in the Saudi context including insufficient community awareness of the role of the ED and perceived lack of access to primary healthcare services.

The German Version of the Manchester Triage System and its quality criteria--first assessment of validity and reliability

Background

The German Version of the Manchester Triage System (MTS) has found widespread use in EDs across German-speaking Europe. Studies about the quality criteria validity and reliability of the MTS currently only exist for the English-language version. Most importantly, the content of the German version differs from the English version with respect to presentation diagrams and change indicators, which have a significant impact on the category assigned. This investigation offers a preliminary assessment in terms of validity and inter-rater reliability of the German MTS.

Methods

Construct validity of assigned MTS level was assessed based on comparisons to hospitalization (general / intensive care), mortality, ED and hospital length of stay, level of prehospital care and number of invasive diagnostics. A sample of 45,469 patients was used. Inter-rater agreement between an expert and triage nurses (reliability) was calculated separately for a subset group of 167 emergency patients.

Results

For general hospital admission the area under the curve (AUC) of the receiver operating characteristic was 0.749; for admission to ICU it was 0.871. An examination of MTS-level and number of deceased patients showed that the higher the priority derived from MTS, the higher the number of deaths (p<0.0001 / χ² Test). There was a substantial difference in the 30-day survival among the 5 MTS categories (p<0.0001 / log-rank test).The AUC for the predict 30-day mortality was 0.613. Categories orange and red had the highest numbers of heart catheter and endoscopy. Category red and orange were mostly accompanied by an emergency physician, whereas categories blue and green were walk-in patients. Inter-rater agreement between expert triage nurses was almost perfect (κ = 0.954).

Conclusion

The German version of the MTS is a reliable and valid instrument for a first assessment of emergency patients in the emergency department.

Implementing an obstetric triage acuity scale: interrater reliability and patient flow analysis

A 5-category Obstetric Triage Acuity Scale (OTAS) was developed with a comprehensive set of obstetrical determinants. The objectives of this study were as follows: (1) to test the interrater reliability of OTAS and (2) to determine the distribution of patient acuity and flow by OTAS level. To test the interrater reliability, 110 triage charts were used to generate vignettes and the consistency of the OTAS level assigned by 8 triage nurses was measured. OTAS performed with substantial (Kappa, 0.61 - 0.77, OTAS 1-4) and near perfect correlation (0.87, OTAS 5). To assess patient flow, the times to primary and secondary health care provider assessments and lengths of stay stratified by acuity were abstracted from the patient management system. Two-thirds of triage visits were low acuity (OTAS 4, 5). There was a decrease in length of stay (median [interquartile range], minutes) as acuity decreased from OTAS 1 (120.0 [156.0] minutes) to OTAS 3 (75.0 [120.8]). The major contributor to length of stay was time to secondary health care provider assessment and this did not change with acuity. The percentage of patients admitted to the antenatal or birthing unit decreased from 80% (OTAS 1) to 12% (OTAS 5). OTAS provides a reliable assessment of acuity and its implementation has allowed for triaging of obstetric patients based on acuity, and a more in-depth assessment of the patient flow. By standardizing assessment, OTAS allows for opportunities to improve performance and make comparisons of patient care and flow across organizations.

Estimating the waiting time of multi-priority emergency patients with downstream blocking

To characterize the coupling effect between patient flow to access the emergency department (ED) and that to access the inpatient unit (IU), we develop a model with two connected queues: one upstream queue for the patient flow to access the ED and one downstream queue for the patient flow to access the IU. Building on this patient flow model, we employ queueing theory to estimate the average waiting time across patients. Using priority specific wait time targets, we further estimate the necessary number of ED and IU resources. Finally, we investigate how an alternative way of accessing ED (Fast Track) impacts the average waiting time of patients as well as the necessary number of ED/IU resources. This model as well as the analysis on patient flow can help the designer or manager of a hospital make decisions on the allocation of ED/IU resources in a hospital.

The oncology acuity tool: a reliable, valid method for measuring patient acuity for nurse assignment decisions

BACKGROUND AND PURPOSE

Matching nurse assignments with patient acuity has critical implications for providing safe, effective, and efficient care. Despite this, we lack well-established methods for accurate assessment of acuity. This study aimed to evaluate the reliability and validity of the Oncology Acuity Tool (OAT), which is used for determining nurse assignments.

METHODS

Inter-rater reliability and concurrent validity were assessed via surveys of current users of the tool. Content validity data were collected from expert oncology nurses. Predictive validity was assessed by tracking patients who sustained either of two acute events.

RESULTS

Findings included high inter-rater reliability, moderately strong concurrent validity, and moderate content validity. Acuity significantly predicted rapid response team consults but not falls.

CONCLUSIONS

The OAT demonstrated sufficient reliability and validity for measuring acuity prospectively in this population.

Development and Validation of Models to Predict Hospital Admission for Emergency Department Patients

Background: Boarding, or patients waiting to be admitted to hospital, has been shown as a significant contributing factor at overcrowding in emergency departments (ED). Predicting hospital admission at triage has been proposed as having the potential to help alleviate ED overcrowding. The objective of this paper is to develop and validate a model to predict hospital admission at triage to help alleviate ED overcrowding. Methods: Administrative records between April 1, 2010 and November 31, 2010 in an adult ED were used to derive and validate two prediction models, one based on Coxian phase type distribution (the PH model), the other based on logistic regression. Separate data sets were used for model development (data between April 1, 2010 and July 31, 2010) and validation (data between August 1, 2010 and November 31, 2010). Results: There were a total of 14,542 ED visits and 2,602 (17.89%) hospital admissions in the derivation cohort. In both models, acuity levels, model of arrival, and main reason of the visit are strong predictors of hospital admission; number of patients at the ED, as well as gender, are also predictors, albeit with ORs closer to 1. Patient age and timing of visits are not strong predictors. The PH model has an AUC of 0.89 compared with AUC of 0.83 for logistic regression model; with a cut- off value of 0.50, the PH model correctly predicted 86.3% of visits, compared to 84.4% for the logistic regression model. Results of the validation cohort were similar: the PH model has an AUC of 0.88, compared to AUC of 0.83 for the logistic model. Conclusions: PH and logistic models can be used to provide reasonably accurate prediction of hospital admission for ED patients, with the PH model offering more accurate predictions

Child maltreatment and repeat presentations to the emergency department for suicide-related behaviors

OBJECTIVES

To identify factors associated with repeat emergency department (ED) presentations for suicide-related behaviors (SRB) - hereafter referred to as repetition - among children/youth to aid secondary prevention initiatives. To compare rates of repetition in children/youth with substantiated maltreatment requiring removal from their parental home with their peers in the general population.

METHODS

A population-based (retrospective) cohort study was established for children/youth with a first ED SRB presentation at risk for repetition in the Province of Ontario, Canada between 1 January 2004 and 31 December 2008. Children/youth legally removed from their parental home because of substantiated maltreatment (n=179) and their population-based peers (n=6,305) were individually linked to administrative health care records over time to ascertain social, demographic, and clinical information and subsequent ED presentations for SRB during follow-up. These children/youth were described and their repetition-free probabilities over time compared. To identify factors associated with repetition we fit multivariable, recurrent event survival analysis models stratified by repetition and present unadjusted and adjusted hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

Children/youth with substantiated maltreatment (as noted) were two times more likely to have repetition than their peers after adjustments for social, demographic, and clinical factors (conditional on prior ED SRB presentations). A number of these factors were independently associated with repetition. No one factor distinguished between having a first and second repetition nor was more strongly associated with repetition than another.

CONCLUSIONS

The risk of repetition is higher in children with substantiated maltreatment (as noted) than their peers. No one factor stood out as predictive of repetition. Implications for secondary prevention initiatives include a non-selective approach, sensitive to family difficulties and the need to better contextualize repetition and harness data linkages.

Facilitators and barriers to safe emergency department transitions for community dwelling older people with dementia and their caregivers: a social ecological study

BACKGROUND

Internationally, older adults visit the ED at a rate higher than other age groups. Little attention has been given to ED care for older people with dementia, although concern for such care is growing with the increasing number of individuals worldwide affected by this significant disabling problem. It is critical to understand ED transitional processes and consequences because the complexity of dementia care poses multiple challenges to optimizing safety, effectiveness and quality of care during admission, assessment, and treatment in this setting.

METHOD

Using an interpretive, descriptive exploratory design with three iterative, interrelated phases, we conducted interviews, created a photographic narrative journal (PNJ), and finally held photo elicitation focus groups to identify factors that facilitate or impede safe transitional care for community dwelling older adults with dementia in two Canadian emergency departments, and to identify practice solutions for nurses. We purposively sampled to recruit ten older adult-family caregiver dyads, ten ED RNs, and four Nurse Practitioners. Data were analyzed using constant comparative analysis.

RESULTS

Four interconnected reinforcing consequences emerged from our analysis: being under-triaged; waiting and worrying about what was wrong; time pressure with lack of attention to basic needs; and, relationships and interactions leading to feeling ignored, forgotten and unimportant. Together these consequences stem from a triage system that does not recognize atypical presentation of disease and illness. This potentiated a cascade of vulnerability in older people with dementia and their caregivers. Nurses experienced time pressure challenges that impeded their ability to be responsive to basic care needs.

CONCLUSIONS

In an aging population where dementia is becoming more prevalent, the unit of care in the ED must include both the older person and their family caregiver. Negative reinforcing consequences can be interrupted when nurses communicate and engage more regularly with the older adult-caregiver dyad to build trust. System changes are also needed to support the ability of nurses to carry out best practices.

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.

Mass-Gathering Medicine: Creation of an Online Event and Patient Registry

Introduction/Problem

A review of the mass-gathering medicine literature confirms that the research community currently lacks a standardized approach to data collection and reporting in relation to large-scale community events. This lack of consistency, particularly with regard to event characteristics, patient characteristics, acuity determination, and reporting of illness and injury rates makes comparisons between and across events difficult. In addition, a lack of access to good data across events makes planning medical support on-site, for transport, and at receiving hospitals, challenging. This report describes the development of an Internet-hosted, secure registry for event and patient data in relation to mass gatherings.

Methods

Descriptive; development and pilot testing of a Web-based event and patient registry.

Results

Several iterations of the registry have resulted in a cross-event platform for standardized data collection at a variety of events. Registry and reporting field descriptions, successes, and challenges are discussed based on pilot testing and early implementation over two years of event enrollment.

Conclusion

The Mass-Gathering Medicine Event and Patient Registry provides an effective tool for recording and reporting both event and patient-related variables in the context of mass-gathering events. Standardizing data collection will serve researchers and policy makers well. The structure of the database permits numerous queries to be written to generate standardized reports of similar and dissimilar events, which supports hypothesis generation and the development of theoretical foundations in mass-gathering medicine.

Triage During Mass Gatherings

Triage is a complex process and is one means for determining which patients most need access to limited resources. Triage has been studied extensively, particularly in relation to triage in overcrowded emergency departments, where individuals presenting for treatment often are competing for the available stretchers. Research also has been done in relation to the use of prehospital and field triage during mass-casualty incidents and disasters.

In contrast, scant research has been done to develop and test an effective triage approach for use in mass-gathering and mass-participation events, although there is a growing body of knowledge regarding the health needs of persons attending large events. Existing triage and acuity scoring systems are suboptimal for this unique population, as these events can involve high patient presentation rates (PPR) and, occasionally, critically ill patients. Mass-gathering events are dangerous; a higher incidence of injury occurs than would be expected from general population statistics.

The need for an effective triage and acuity scoring system for use during mass gatherings is clear, as these events not only create multiple patient encounters, but also have the potential to become mass-casualty incidents. Furthermore, triage during a large-scale disaster or mass-casualty incident requires that multiple, local agencies work together, necessitating a common language for triage and acuity scoring.

In reviewing existing literature with regard to triage systems that might be employed for this population, it is noted that existing systems are biased toward traumatic injuries, usually ignoring mitigating factors such as alcohol and drug use and environmental exposures. Moreover, there is a substantial amount of over-triage that occurs with existing prehospital triage systems, which may lead to misallocation of limited resources. This manuscript presents a review of the available literature and proposes a triage system for use during mass gatherings that also may be used in the setting of mass-casualty incidents or disaster responses.

A comparison of adherence to correctly documented triage level of critically ill patients between emergency department and the ambulance service nurses

Priority or triage has always occurred in emergency care. Today it is performed by both nurses in emergency departments (EDs) and ambulance services (ASs) to ensure patient safety. Recent studies have shown that nurses are unlikely to change their first impressions and patients suffering from blunt trauma are undertriaged. Our study aimed to compare and evaluate the adherence to correct triage level documentation, between nurses in the ED and the AS, according to current regulations. Of 592 analysed triage records from a university, a central and a district hospital, the adherence was 64% by ED nurses and 43% by AS nurses (p<0.001), but individual percentages ranged from 27% to 88%. Patient safety is jeopardised when nurses do not adhere to the triage system and do not correctly document the triage level. Internal feedback and control are two approaches to improve the patient outcome, indicating that organisational actions must be taken.

Evaluating the effect of clinical decision units on patient flow in seven Canadian emergency departments

OBJECTIVES

To evaluate the effect of emergency department (ED) clinical decision units (CDUs) on overall ED patient flow in a pilot project funded in 2008 by the Ontario Ministry of Health and Long-Term Care (MOHLTC).

METHODS

A retrospective analysis of unscheduled ED visits at seven CDU pilot and nine control sites was conducted using administrative data. The authors examined trends in CDU utilization and compared outcomes between pilot-CDU and control sites 1 year prior to implementation, with the first 18 months of CDU operation. Sites that were unsuccessful in their applications for CDU program funding served as controls. Outcomes included ED length of stay (LOS), admission rates, and ED revisit rates.

RESULTS

At CDU sites, roughly 4% of ED patients were admitted to CDUs. The presence of a pilot-CDU was independently associated with a small reduction in ED LOS for all low-acuity patients (-0.14 hour, 95% confidence interval [CI]=-0.22 to -0.07) and nonadmitted patients (-0.11 hour, 95% CI=-0.16 to -0.07). A small independent effect on absolute hospital admission rate for all high-acuity patients (-0.8%, 95% CI=-1.5% to -0.03%) and moderate-acuity patients (-0.6%, 95% CI=-1.1% to -0.2%) was also observed. Pilot-CDUs were not associated with changes in ED revisit rates.

CONCLUSIONS

With only 4% of ED patients admitted to CDUs, the potential for efficiency gains in these EDs was limited. Nonetheless, these findings suggest small improvements in the operation of the ED through CDU implementation. Although marginal, the observed effects of CDU operation were in the desired direction of reduced ED LOS, reduced admission rate, and no increase in ED revisit rate.

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 data- base 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.

Using a theory to understand triage decision making

The purpose of this discussion is to present triage decision making research within the context of the Revised Cognitive Continuum Theory. Triage is an essential clinical skill in emergency nursing. Understanding the best way to facilitate this skill is vital when educating new nurses or providing continuing education to practicing nurses. Delineating research evidence within a theory allows clinical educators to understand practices that foster successful triage skills and permits the grounding of educational strategies within a theoretical framework.

Development and validation of the excess mortality ratio-based Emergency Severity Index

PURPOSE

The purpose of this study is to develop and validate the excess mortality ratio-based Emergency Severity Index (EMR-ESI) that feasibly and objectively assesses the severity of emergency department (ED) patients based on their chief complaints.

METHODS

We used data from the National Emergency Department Information System of Korea from January 2006 to December 2009. We obtained information on mortality and the corresponding chief complaints exhibited by patients presenting to all EDs. The EMR-ESI was computed from the ratio of sex-age standardized hospital mortality for each chief complaint and the sex-age standardized mortality of the entire population of Korea. We tested the discriminatory power of the EMR-ESI on the prediction of hospital outcomes using the area under the receiver operating characteristic curve (AUC) from a multivariate logistic regression model. This model was adjusted for clinical parameters, and the goodness of fit was estimated using the Hosmer-Lemeshow logistic model.

RESULTS

Included in the study were 4 713 462 patients who presented 7557 chief complaint codes from 2006 to 2008. The EMR-ESI had a range of 0 to 6389.45 (mean ± SD, 1.11 ± 4.67; median, 0.70). The adjusted odds ratio of the EMR-ESI (unit, 1.0) for hospital mortality was 1.11 (95% confidence interval, 1.11-1.12). The AUCs for predicting hospital mortality, ED mortality, admission mortality, and admission were 0.95, 0.98, 0.90, and 0.74, respectively. There were 3 422 865 patients from 2009 who were included for external validation, and the AUCs for predicting mortality in the hospital, the ED, the inpatient ward, and for predicting admission were 0.95, 0.99, 0.90, and 0.75, respectively.

CONCLUSION

The EMR-ESI was notably useful in predicting hospital mortality and the admission of emergency patients.

Implantação do sistema acolhimento com Classificação e Avaliação de Risco e uso do Fluxograma Analisador

O presente estudo teve como objetivo relatar o processo de implantação do sistema Acolhimento com Classificação e Avaliação de Risco e o uso do Fluxograma Analisador, no Serviço Hospitalar de Emergência da Santa Casa de Misericórdia de Ourinhos, Estado de São Paulo. A implantação do sistema foi subdividida nas etapas: sensibilização dos profissionais, readequação de recursos, execução do planejamento e avaliação. À organização do fluxo de pacientes, foram utilizados Fluxogramas Funcionais que, depois de alguns ajustes, resultaram em um Fluxograma Analisador. O Fluxograma Analisador resultante proporcionou a visualização gráfica das etapas do atendimento e direcionou todos os portadores de agravos não emergenciais à consulta de enfermagem. Conclui-se que o Fluxograma Analisador foi uma ferramenta essencial ao processo de implantação do Acolhimento com Classificação e Avaliação de Risco porque, ao definir as etapas do fluxo para o atendimento, o serviço se tornou mais organizado, humano e seguro.

The development of an obstetric triage acuity tool

The purpose of this article is to describe the journey a multicampus hospital system took to improve the obstetric triage process. A review of literature revealed no current comprehensive obstetric acuity tool, and thus our team developed a tool with a patient flow process, revised and updated triage nurse competencies, and then educated the nurses about the new tool and process. Data were collected to assess the functionality of the new process in assigning acuity upon patient arrival, conveying appropriate acuities based on patient complaints, and initiating the medical screening examination, all within prescribed time intervals. Initially data indicated that processes were still not optimal, and re-education was provided for all triage nurses. This improved all data points. The result of this QI project is that our patients are now seen based on their acuity within designated time frames.

A method for reviewing the accuracy and reliability of a five-level triage process (canadian triage and acuity scale) in a community emergency department setting: building the crowding measurement infrastructure

Objectives. Triage data are widely used to evaluate patient flow, disease severity, and emergency department (ED) workload, factors used in ED crowding evaluation and management. We defined an indicator-based methodology that can be easily used to review the accuracy of Canadian Triage and Acuity Scale (CTAS) performance. Methods. A trained nurse reviewer (NR) retrospectively triaged two separate month's ED charts relative to a set of clinical indicators based on CTAS Chief Complaints. Interobserver reliability and accuracy were compared using Kappa and comparative statistics. Results. There were 2838 patients in Trial 1 and 3091 in Trial 2. The rate of inconsistent triage was 14% and 16% (Kappa 0.596 and 0.604). Clinical Indicators “pain scale, chest pain, musculoskeletal injury, respiratory illness, and headache” captured 68% and 62% of visits. Conclusions. We have demonstrated a system to measure the levels of process accuracy and reliability for triage over time. We identified five key clinical indicators which captured over 60% of visits. A simple method for quality review uses a small set of indicators, capturing a majority of cases. Performance consistency and data collection using indicators may be important areas to direct training efforts.

Impact of the ABCDE triage in primary care emergency department on the number of patient visits to different parts of the health care system in Espoo City

BACKGROUND

Many Finnish emergency departments (ED) serve both primary and secondary health care patients and are therefore referred to as combined emergency departments. Primary care doctors are responsible for the initial assessment and treatment. They, thereby, also regulate referral and access to secondary care. Primary health care EDs are easy for the public to access, leading to non-acute patient visits to the emergency department. This has caused increased queues and unnecessary difficulties in providing immediate treatment for urgent patients. The primary aim of this study was to assess whether the flow of patients was changed by implementing the ABCDE-triage system in the EDs of Espoo City, Finland.

METHODS

The numbers of monthly visits to doctors were recorded before and after intervention in Espoo primary care EDs. To study if the implementation of the triage system redirects patients to other health services, the numbers of monthly visits to doctors were also scored in the private health care, the public sector health services of Espoo primary care during office hours and local secondary health care ED (Jorvi hospital). A face-to-face triage system was applied in the primary care EDs as an attempt to provide immediate treatment for the most acute patients. It is based on the letters A (patient sent directly to secondary care), B (to be examined within 10 min), C (to be examined within 1 h), D (to be examined within 2 h) and E (no need for immediate treatment) for assessing the urgency of patients' treatment needs. The first step was an initial patient assessment by a health care professional (triage nurse). The introduction of this triage system was combined with information to the public on the "correct" use of emergency services.

RESULTS

After implementation of the ABCDE-triage system the number of patient visits to a primary care doctor decreased by up to 24% (962 visits/month) as compared to the three previous years in the EDs. The Number of visits to public sector GPs during office hours did not alter. Implementation of ABCDE-triage combined with public guidance was associated with decreased total number of doctor visits in public health care. During same period, the number of patient visits in the private health care increased. Simultaneously, the number of doctor visits in secondary health care ED did not alter.

CONCLUSIONS

The present ABCDE-triage system combined with public guidance may reduce patient visits to primary health care EDs but not to the secondary health care EDs. Limiting the access of less urgent patients to ED may redirect the demands of patients to private sector rather than office hours GP services.

A retrospective cohort study of stroke onset: implications for characterizing short term effects from ambient air pollution

BACKGROUND

Case-crossover studies used to investigate associations between an environmental exposure and an acute health response, such as stroke, will often use the day an individual presents to an emergency department (ED) or is admitted to hospital to infer when the stroke occurred. Similarly, they will use patient's place of residence to assign exposure. The validity of using these two data elements, typically extracted from administrative databases or patient charts, to define the time of stroke onset and to assign exposure are critical in this field of research as air pollutant concentrations are temporally and spatially variable. Our a priori hypotheses were that date of presentation differs from the date of stroke onset for a substantial number of patients, and that assigning exposure to ambient pollution using place of residence introduces an important source of exposure measurement error. The objective of this study was to improve our understanding on how these sources of errors influence risk estimates derived using a case-crossover study design.

METHODS

We sought to collect survey data from stroke patients presenting to hospital EDs in Edmonton, Canada on the date, time, location and nature of activities at onset of stroke symptoms. The daily mean ambient concentrations of NO₂ and PM(2.5) on the self-reported day of stroke onset was estimated from continuous fixed-site monitoring stations.

RESULTS

Of the 336 participating patients, 241 were able to recall when their stroke started and 72.6% (95% confidence interval [CI]: 66.9-78.3%) experienced stroke onset the same day they presented to the ED. For subjects whose day of stroke onset differed from the day of presentation to the ED, this difference ranged from 1 to 12 days (mean = 1.8; median = 1). In these subjects, there were no systematic differences in assigned pollution levels for either NO₂ or PM(2.5) when day of presentation rather than day of stroke onset was used. At the time of stroke onset, 89.9% (95% CI: 86.6-93.1%) reported that they were inside, while 84.5% (95% CI: 80.6 - 88.4%) reported that for most of the day they were within a 15 minute drive from home. We estimated that due to the mis-specification of the day of stroke onset, the risk of hospitalization for stroke would be understated by 15% and 20%, for NO₂ and PM(2.5), respectively.

CONCLUSIONS

Our data suggest that day of presentation and residential location data obtained from administrative records reasonably captures the time and location of stroke onset for most patients. Under these conditions, any associated errors are unlikely to be an important source of bias when estimating air pollution risks in this population.

Temporal changes in emergency department triage of patients with acute myocardial infarction and the effect on outcomes

BACKGROUND

All patients who present to an emergency department (ED) are triaged. The ED triage score may determine when patients are seen by a physician. Half of patients with acute myocardial infarction (AMI) were given a low priority score in Ontario in 2000/2001. We assessed the appropriateness of ED triage and its association with quality indicators and outcomes in a more recent AMI cohort and compared this with previous findings.

METHODS

We conducted a retrospective cohort study of a population-based cohort of patients with AMI admitted to 96 hospitals in Ontario, Canada, in 2004/2005. Outcome measures included rate of low-priority ED triage (score of 3, 4, or 5), compared with an earlier cohort (fiscal year 2000) at the same sites, and the adjusted effect of low-priority ED triage on door-to-electrocardiogram, door-to-needle, and door-to-balloon time; hospital length of stay (LOS); and mortality.

RESULTS

Among 6,605 patients with AMI, low-priority triage was less frequent than in the earlier cohort, at 33.3% versus 50.3%. In patients with ST-segment elevation myocardial infarction (STEMI), it was 25.9%, versus 43.8% previously. Between cohorts, the greatest improvement in triage occurred in patients with chest pain, in those seen at higher AMI volume EDs, and in ambulatory patients; patients seen at low AMI volume EDs, those with diabetes, and the elderly showed the least improvement. Being assigned a low-priority triage score was associated with an adjusted increase in median door-to-electrocardiogram and door-to-needle time of 12.2 (P < .001) and 20.7 minutes (P < .001), respectively, longer than in the earlier cohort (4.4 and 15.1 minutes). It was associated with hospital LOS >75th percentile (odds ratio [OR] 1.25, P < .001), and higher 90-day (OR 1.50, P = .02) and 1-year mortality (OR 1.37, P = .05) in patients with STEMI.

CONCLUSION

Emergency department triage of patients with AMI improved substantially over 5 years. For the third of patients with AMI who continue to receive a low priority score, including 25% of patients with STEMI, the associated delays in diagnosis and therapy were greater than previously and were associated with increased hospital LOS and mortality. Given the impact of this initial, cursory assessment, hospital systems should consider monitoring the quality of their ED triage.

Adherence to the guideline 'Triage in emergency departments': a survey of Dutch emergency departments

AIMS AND OBJECTIVES

The aim of this study was to evaluate the adherence to the 2004 guideline Triage in emergency departments three years after dissemination in Dutch emergency departments.

BACKGROUND

In 2004, a Dutch guideline Triage in emergency departments was developed. Triage is the first step performed by nurses when a patient arrives at an emergency department. It includes the prioritisation of patients to ensure that doctors see patients with the highest medical needs first. Although the national guideline was developed and disseminated in 2004, three years on there was no insight into the level of implementation of the guideline in practice.

DESIGN

A cross-sectional descriptive design.

METHODS

In February 2007, data were collected from ward managers and triage nurses at all emergency departments in the Netherlands (n = 108), using a questionnaire that was based on the recommendations and performance indicators of the guideline.

RESULTS

In total, 79% of all 108 Dutch emergency departments responded. The main findings showed that over 31% of the emergency departments did not use a triage system. Emergency departments using the Manchester Triage System had a mean adherence rate of 61% of the guideline's recommendations and emergency departments using the Emergency System Index adhered to a mean of 65%.

CONCLUSION

The guideline Triage in emergency departments was disseminated in 2004, but results from this study indicate that an improvement in adherence to this guideline is required.

RELEVANCE TO CLINICAL PRACTICE

Adherence to guidelines is important to standardise practice to ensure that patients receive the appropriate treatment and to improve quality of care.

Exploring differences in the clinical management of pediatric mental health in the emergency department

OBJECTIVE

: We examine psychiatric and pediatric clinical management of pediatric mental health in the emergency department (ED).

METHODS

: We conducted a retrospective review of health care delivery with a random sample of all pediatric mental health presentations (≤18 years) to 2 urban tertiary care EDs between 2004 and 2006 (N = 580).

RESULTS

: The EDs differed significantly in services offered. General emergency medicine-trained physicians provided care at 1 site (54.6%) with a number of visits also managed by a psychiatric crisis team (45.4%). Care at the other ED was delivered by pediatric emergency medicine-trained physicians (99.4%) with no regular on-site psychiatric services. The most common assessment provided across sites and all presentations was for suicidality (66.2%). After controlling for potential confounders, receipt of clinical assessment for homicidality, mood, or reality testing differed between EDs (P = 0.044, P = 0.006, and P = 0.002) with more assessments documented at the psychiatric-resourced ED. Brief counseling was lacking for visits (absence of documentation: 56.1% pediatric-resourced, 23.1% psychiatric-resourced ED); there was no evidence of site differences in provision. More psychiatric consultation was provided at the psychiatric-resourced ED (34.1% vs 27.4%, P = 0.030). Discharge recommendations were lacking in both EDs but were more incomplete for pediatric-resourced ED visits (P = 0.035).

CONCLUSIONS

: Consistent and comprehensive clinical management of pediatric mental health presentations was lacking in EDs that had pediatric and psychiatric resources. Prospective evaluations are needed to determine the effect of current clinical ED practices on patient and family outcomes, including symptom reduction and stress, as well as subsequent system use.
