Emergency department overcrowding and children

Smartphone App PACOM to Provide Advice Regarding Self-Triage for the Acute Primary Care Needs of Children: Accuracy of Algorithms

BACKGROUND

We developed a phone app, PACOM (Parents Application Conseils et Orientation Médicale), to provide medical advice to caregivers based on several algorithms and a series of binary questions related to children's symptoms. We compared the recommendations of the PACOM algorithms and clinicians for children visiting the emergency department (ED).

METHODS

Between January and February 2022, we prospectively recruited French-speaking parents of children without any chronic disease who presented to the pediatric ED with any complaint except for mental health problems or trauma. Isolated head trauma was included. They completed questionnaires and the various PACOM algorithms. The first algorithm, called "Quick Look," was developed to identify children with life-threatening emergencies. The standard reference was the advice of the ED clinicians who were blinded to the parental responses to the PACOM algorithm questions. The recommendations included "call urgent medical support," "visit the ED," "visit your general practitioner within 24 hours," and "visit your general practitioner in the next days."

RESULTS

The study included 269 parents. The response rate was 75%. The median age of the children was 3 years with interquartile range: 1 to 7 years. In total, 268 children completed the "Quick Look," 141 "fever," 83 "abdominal pain," 72 "cough," 70 "vomiting," 130 questionnaires relative to other proposed symptoms, and 70 "other symptom" questionnaires. The PACOM recommendations were "call urgent medical assistant" for 98 children, "ED visit" for 131, "visit general practitioner within 24 hours" for 13, and "visit general practitioner during the next days" for 24. The sensitivity and specificity of the PACOM recommendation to "call urgent medical support or visit the ED" were 98.1% (95% confidence interval, 95.5-100.00) and 22.1% (95% confidence interval, 15.3-28.8), respectively.

CONCLUSIONS

The PACOM algorithms has high sensitivity but low specificity for reducing ED visits and calls for urgent medical support.

Web-Based Knowledge Translation Tool About Pediatric Acute Gastroenteritis for Parents: Pilot Randomized Controlled Trial

BACKGROUND

Acute gastroenteritis (AGE) in children is a leading cause of emergency department (ED) visits, resulting in substantial health care costs and stress for families and caregivers. The majority of pediatric AGE cases are caused by viral infections and can be managed at home using strategies to prevent dehydration. To increase knowledge of, and support health decision-making for, pediatric AGE, we developed a knowledge translation (KT) tool (fully automated web-based whiteboard animation video).

OBJECTIVE

The aim of this study was to assess the potential effectiveness of the web-based KT tool in terms of knowledge, health care decision-making, use of resources, and perceived benefit and value.

METHODS

A convenience sample of parents was recruited between December 18, 2020, and August 10, 2021. Parents were recruited in the ED of a pediatric tertiary care hospital and followed for up to 14 days after the ED visit. The eligibility criteria included parent or legal guardian of a child aged <16 years presenting to the ED with an acute episode of diarrhea or vomiting, ability to communicate in English, and agreeable to follow-up via email. Parents were randomized to receive the web-based KT tool (intervention) about AGE or a sham video (control) during their ED visit. The primary outcome was knowledge assessed before the intervention (baseline), immediately after the intervention, and at follow-up 4 to 14 days after ED discharge. Other outcomes included decision regret, health care use, and KT tool usability and satisfaction. The intervention group participants were invited to participate in a semistructured interview to gather additional feedback about the KT tool.

RESULTS

A total of 103 parents (intervention: n=51, 49.5%, and control: n=52, 50.5%) completed the baseline and postintervention assessments. Of these 103 parents, 78 (75.7%; intervention: n=36, 46%, and control: n=42, 54%) completed the follow-up questionnaire. Knowledge scores after the intervention (mean 8.5, SD 2.6 vs mean 6.3, SD 1.7; P<.001) and at follow-up (mean 9.1, SD 2.7 vs mean 6.8, SD 1.6; P<.001) were significantly higher in the intervention group. After the intervention, parents in the intervention group reported greater confidence in knowledge than those in the control group. No significant difference in decision regret was found at any time point. Parents rated the KT tool higher than the sham video across 5 items assessing usability and satisfaction.

CONCLUSIONS

The web-based KT tool improved parental knowledge about AGE and confidence in their knowledge, which are important precursors to behavior change. Further research is needed into understanding what information and delivery format as well as other factors influence parents' decision-making regarding their child's health.

Machine Learning-Based Prediction of Hospital Admission Among Children in an Emergency Care Center

OBJECTIVES

Machine learning-based prediction of hospital admissions may have the potential to optimize patient disposition and improve clinical outcomes by minimizing both undertriage and overtriage in crowded emergency care. We developed and validated the predictive abilities of machine learning-based predictions of hospital admissions in a pediatric emergency care center.

METHODS

A prognostic study was performed using retrospectively collected data of children younger than 16 years who visited a single pediatric emergency care center in Osaka, Japan, between August 1, 2016, and October 15, 2019. Generally, the center treated walk-in children and did not treat trauma injuries. The main outcome was hospital admission as determined by the physician. The 83 potential predictors available at presentation were selected from the following categories: demographic characteristics, triage level, physiological parameters, and symptoms. To identify predictive abilities for hospital admission, maximize the area under the precision-recall curve, and address imbalanced outcome classes, we developed the following models for the preperiod training cohort (67% of the samples) and also used them in the 1-year postperiod validation cohort (33% of the samples): (1) logistic regression, (2) support vector machine, (3) random forest, and (4) extreme gradient boosting.

RESULTS

Among 88,283 children who were enrolled, the median age was 3.9 years, with 47,931 (54.3%) boys and 1985 (2.2%) requiring hospital admission. Among the models, extreme gradient boosting achieved the highest predictive abilities (eg, area under the precision-recall curve, 0.26; 95% confidence interval, 0.25-0.27; area under the receiver operating characteristic curve, 0.86; 95% confidence interval, 0.84-0.88; sensitivity, 0.77; and specificity, 0.82). With an optimal threshold, the positive and negative likelihood ratios were 4.22, and 0.28, respectively.

CONCLUSIONS

Machine learning-based prediction of hospital admissions may support physicians' decision-making for hospital admissions. However, further improvements are required before implementing these models in real clinical settings.

Nonurgent Visits to the Pediatric Emergency Department before and during the First Peak of the COVID-19 Pandemic

Background

Nonurgent visits in pediatric Emergency Departments are a growing burden. In order to find predictors for those nonurgent visits, we performed a retrospective analysis of unscheduled visits at the Pediatric Emergency Department of the University Hospital of Bonn, Germany, in the year 2017. Additionally, we compared these findings to unscheduled visits during the first peak of the worldwide pandemic of the Coronavirus disease 2019, to see if there would be an effect on nonurgent pediatric Emergency Department attendances.

Methods

For our retrospective cohort study, we analyzed more than 5.000 visits at the pediatric Emergency Department of the University Hospital of Bonn, Germany, before and during the first peak of the ongoing worldwide pandemic of the Coronavirus disease 2019, particularly with regard to their urgency. Data included gender, age, zip code, urgency, and preexisting conditions.

Results

Our study shows that more than half of unscheduled pediatric Emergency Department visits (69%) at the University Hospital in Bonn are for nonurgent reasons, with short living distance being a factor to present children to a pediatric Emergency Department, even with minor complaints. During the first peak of the pandemic of the Coronavirus disease 2019, nonurgent visits decreased significantly, potentially due to hesitation to attend a pediatric Emergency Department with minor issues, fearing an infection with SARS-CoV-2 at the hospital.

Conclusion

Many people use pediatric Emergency Departments for nonemergency complaints. In order to address the reasons for nonurgent visits to pediatric Emergency Departments and to prevent parents from doing so, further studies and targeted education concepts for parents are needed.

Real-Time Measurement of Crowding in Pediatric Emergency Department: Derivation and Validation Using Consensual Perception of Crowding (SOTU-PED)

ABSTRACT

Our study aimed to develop and validate a real-time crowding composite scale for pediatric emergency department (PED). The study took place in one teaching PED for 2 months. The outcome was the perception of crowding evaluated by triage nurses and pediatricians on a 10-level Likert scale. Triage nurses evaluated crowding at each moment of a child's admission and pediatrician at each moment of a child's discharge. The outcome was the hourly mean of all evaluations of crowding (hourly crowding perception). For analysis, originally, we only selected hours during which more than 2 nurses and more than 2 pediatricians evaluated crowding and, moreover, during which evaluations were the most consensual. As predictors, we used hourly means of 10 objective crowding indicators previously selected as consensual in a published French national Delphi study and collected automatically in our software system. The model (SOTU-PED) was developed over a 1-month data set using a backward multivariable linear regression model. Then, we applied the SOTU-PED model on a 1-month validation data set. During the study period, 7341 children were admitted in the PED. The outcome was available for 1352/1392 hours, among which 639 were included in the analysis as "consensual hours." Five indicators were included in the final model, the SOTU-PED (R2 = 0.718). On the validation data set, the correlation between the outcome (perception of crowding) and the SOTU-PED was 0.824. To predict crowded hours (hourly crowding perception >5), the area under the curve was 0.957 (0.933-0.980). The positive and negative likelihood ratios were 8.16 (3.82-17.43) and 0.153 (0.111-0.223), respectively. Using a simple model, it is possible to estimate in real time how crowded a PED is.

Impact of Viral Seasonal Outbreaks on Crowding and Health Care Quality in Pediatric Emergency Departments

ABSTRACT

In pediatric emergency departments (PEDs), seasonal viral outbreaks are believed to be associated with an increase of workload, but no quantification of this impact has been published. A retrospective cross-sectional study aimed to measure this impact on crowding and health care quality in PED. The study was performed in 1 PED for 3 years. Visits related to bronchiolitis, influenza, and gastroenteritis were defined using discharge diagnoses. The daily epidemic load (DEL) was the proportion of visits related to one of these diagnoses. The daily mean of 8 crowding indicators (selected in a published Delphi study) was used. A total of 93,976 children were admitted (bronchiolitis, 2253; influenza, 1277; gastroenteritis, 7678). The mean DEL was 10.4% (maximum, 33.6%). The correlation between the DEL and each indicator was significant. The correlation was stronger for bronchiolitis (Pearson R from 0.171 for number of hospitalization to 0.358 for length of stay). Between the first and fourth quartiles of the DEL, a significant increase, between 50% (patients left without being seen) and 8% (patient physician ratio), of all the indicators was observed. In conclusion, seasonal viral outbreaks have a strong impact on crowding and quality of care. The evolution of "patients left without being seen" between the first and fourth quartiles of DEL could be used as an indicator reflecting the capacity of adaptation of an emergency department to outbreaks.

Deep Learning Algorithm to Predict Need for Critical Care in Pediatric Emergency Departments

BACKGROUND AND OBJECTIVES

Emergency department (ED) overcrowding is a national crisis in which pediatric patients are often prioritized at lower levels. Because the prediction of prognosis for pediatric patients is important but difficult, we developed and validated a deep learning algorithm to predict the need for critical care in pediatric EDs.

METHODS

We conducted a retrospective observation cohort study using data from the Korean National Emergency Department Information System, which collected data in real time from 151 EDs. The study subjects were pediatric patients who visited EDs from 2014 to 2016. The data were divided by date into derivation and test data. The primary end point was critical care, and the secondary endpoint was hospitalization. We used age, sex, chief complaint, symptom onset to arrival time, arrival mode, trauma, and vital signs as predicted variables.

RESULTS

The study subjects consisted of 2,937,078 pediatric patients of which 18,253 were critical care and 375,078 were hospitalizations. For critical care, the area under the receiver operating characteristics curve of the deep learning algorithm was 0.908 (95% confidence interval, 0.903-0.910). This result significantly outperformed that of the pediatric early warning score (0.812 [0.803-0.819]), conventional triage and acuity system (0.782 [0.773-0.790]), random forest (0.881 [0.874-0.890]), and logistic regression (0.851 [0.844-0.858]). For hospitalization, the deep-learning algorithm (0.782 [0.780-0.783]) significantly outperformed the other methods.

CONCLUSIONS

The deep learning algorithm predicted the critical care and hospitalization of pediatric ED patients more accurately than the conventional early warning score, triage tool, and machine learning methods.

Prolonged Emergency Department Length of Stay for US Pediatric Mental Health Visits (2005-2015)

BACKGROUND AND OBJECTIVES

Children seeking care in the emergency department (ED) for mental health conditions are at risk for prolonged length of stay (LOS). A more contemporary description of trends and visit characteristics associated with prolonged ED LOS at the national level is lacking in the literature. Our objectives were to (1) compare LOS trends for pediatric mental health versus non-mental health ED visits and (2) explore patient-level characteristics associated with prolonged LOS for mental health ED visits.

METHODS

We conducted an observational analysis of ED visits among children 6 to 17 years of age using the National Hospital Ambulatory Medical Care Survey (2005-2015). We assessed trends in rates of prolonged LOS and the association between prolonged LOS and demographic and clinical characteristics (race and ethnicity, payer type, and presence of a concurrent physical health diagnosis) using descriptive statistics and survey-weighted logistic regression.

RESULTS

From 2005 to 2015, rates of prolonged LOS for pediatric mental health ED visits increased over time from 16.3% to 24.6% (LOS >6 hours) and 5.3% to 12.7% (LOS >12 hours), in contrast to non-mental health visits for which LOS remained stable. For mental health visits, Hispanic ethnicity was associated with an almost threefold odds of LOS >12 hours (odds ratio 2.74; 95% confidence interval 1.69-4.44); there was no difference in LOS by payer type.

CONCLUSIONS

The substantial rise in prolonged LOS for mental health ED visits and disparity for Hispanic children suggest worsening and inequitable access to definitive pediatric mental health care. Policy makers and health systems should work to provide equitable and timely access to pediatric mental health care.

Development and validation of a Paediatric Early Warning Score for use in the emergency department: a multicentre study

BACKGROUND

Paediatric Early Warning Scores (PEWSs) are being used increasingly in hospital wards to identify children at risk of clinical deterioration, but few scores exist that were designed for use in emergency care settings. To improve the prioritisation of children in the emergency department (ED), we developed and validated an ED-PEWS.

METHODS

The TrIAGE project is a prospective European observational study based on electronic health record data collected between Jan 1, 2012, and Nov 1, 2015, from five diverse EDs in four European countries (Netherlands, the UK, Austria, and Portugal). This study included data from all consecutive ED visits of children under age 16 years. The main outcome measure was a three-category reference standard (high, intermediate, low urgency) that was developed as part of the TrIAGE project as a proxy for true patient urgency. The ED-PEWS was developed based on an ordinal logistic regression model, with cross-validation by setting. After completing the study, we fully externally validated the ED-PEWS in an independent cohort of febrile children from a different ED (Greece).

FINDINGS

Of 119 209 children, 2007 (1·7%) were of high urgency and 29 127 (24·4%) of intermediate urgency, according to our reference standard. We developed an ED-PEWS consisting of age and the predictors heart rate, respiratory rate, oxygen saturation, consciousness, capillary refill time, and work of breathing. The ED-PEWS showed a cross-validated c-statistic of 0·86 (95% prediction interval 0·82-0·90) for high-urgency patients and 0·67 (0·61-0·73) for high-urgency or intermediate-urgency patients. A cutoff of score of at least 15 was useful for identifying high-urgency patients with a specificity of 0·90 (95% CI 0·87-0·92) while a cutoff score of less than 6 was useful for identifying low-urgency patients with a sensitivity of 0·83 (0·81-0·85).

INTERPRETATION

The proposed ED-PEWS can assist in identifying high-urgency and low-urgency patients in the ED, and improves prioritisation compared with existing PEWSs.

A Front-end Redesign With Implementation of a Novel "Intake" System to Improve Patient Flow in a Pediatric Emergency Department

Introduction

Children's Hospital Colorado is an academic, tertiary-care Level 1 Trauma Center with an emergency department (ED) that treats >70,000 patients/year. Patient volumes continue to increase, leading to worsening wait times and left-without-being-seen (LWBS) rates. In 2015, the ED's median door-to-provider time was 49 minutes [interquartile range (IQR) = 26-90], with a 3.2% LWBS rate. ED leadership, staff, and providers aimed to improve patient flow with specific goals to (1) decrease door-to-provider times to a median of <30 minutes and (2) decrease annual LWBS rate to <1%.

Methods

An inter-professional team utilized quality improvement and Lean methodology to study, redesign, and implement significant changes to ED front-end processes. Key process elements included (1) new Flow Nurse/EMT roles, (2) elimination of traditional registration and triage processes, (3) immediate "quick registration" and nurse assessment upon walk-in, (4) direct-bedding of patients, and (5) a novel "Intake" system staffed by a pediatric emergency medicine physician.

Results

In the 12 months following full implementation of the new front-end system, the median door-to-provider time decreased 49% to 25 minutes (IQR = 13-50), and the LWBS rate decreased from 3.2% to 1.4% (a 56% relative decrease). Additionally, the percentage of patients seen within 30 minutes of arrival increased, overall ED length-of-stay decreased, patient satisfaction improved, and no worsening of the unexpected 72-hour return rate occurred.

Conclusions

Using quality improvement and Lean methodology, an inter-professional team decreased door-to-provider times and LWBS rates in a large pediatric ED by redesigning its front-end processes and implementing a novel pediatric emergency medicine-led Intake system.

Point-of-Care Ultrasound Could Streamline the Emergency Department Workflow of Clinically Nonspecific Intussusception

OBJECTIVES

The aim of this study was to evaluate whether point-of-care ultrasound (POCUS) for intussusception screening streamlines the workflow of clinically nonspecific intussusception (CNI), an intussusception presenting with only 1 manifestation of the classic triad, and/or vomiting.

METHODS

We reviewed 274 consecutive children with intussusception, aged 6 years or younger, who visited a tertiary care hospital emergency department between May 2012 and April 2016. This period was dichotomized by May 2014 (the "PRE" and "POST" groups), starting point of implementation of the POCUS protocol for intussusception screening. All children with CNI who had positive results on or forwent POCUS underwent radiologist-performed ultrasound (US). We measured and compared emergency department length of stay (EDLOS), the sum of door-to-reduction and observation times, and the frequency of POCUS and positive US results between the 2 groups.

RESULTS

Of 160 children with CNI, 93 visited the emergency department since May 2014. The POST group showed a shorter median EDLOS (856 vs 630 minutes, P < 0.001), door-to-reduction time (137 vs 111 minutes, P = 0.002), and observation time (700 vs 532 minutes, P < 0.001). The POST group had a higher frequency of POCUS (12% vs 60%, P < 0.001) with positive US results (33% vs 59%, P < 0.001). The PRE group had a higher frequency of severe bowel edema (16% vs 1%, P < 0.001). No significant differences were found in the severity, recurrence, admission, and surgery. One child had a false-negative result on POCUS.

CONCLUSIONS

Point-of-care ultrasound could streamline the workflow of CNI via decrease in EDLOS and unnecessary referrals for US.

Evaluation of using pediatric emergency rooms

OBJECTIVE:

The overload of pediatric emergency units around the world has become an increasing problem for patients and health care professionals alike. Researching the features of pediatric emergency services will provide the necessary information for creating an effective emergency medical system, increasing patient satisfaction, and reducing the treatment costs. In this study; we aimed to check the admissions in pediatric emergency rooms, evaluate the effectiveness of emergency service, and develop suitable strategies to increase the amount and quality of medical service given in pediatric emergency rooms.

METHODS:

In this retrospective study, the records of 296,858 (51.2% female, 48.8% male) patient admissions in the emergency rooms and 384,171 (46.3% female, 53.7% male) admissions in the outpatient clinics of eight hospitals between January 2015 and June 2015 were scanned. Out of these hospitals, two facilities were research and training hospitals.

RESULTS:

The average age of patients who were admitted to the emergency room was 89.1 (±21.3) months and the average age of patients admitted to the outpatient clinics was 87.2 (±18.7) months. Upper respiratory tract infection was the most frequent (44.23%) diagnosis in the emergency rooms and most of these infected patients (63.67%) had been admitted to the two training and research hospitals that provide an advanced level of health care. Also, the patient requests for diagnosis were determined to be significantly high in emergency rooms.

CONCLUSION:

Proper understanding of the scope of emergency services is very important in order to provide fast and effective healthcare to the patients who get admitted to emergency rooms and maintain appropriate and judicious use of the resources of emergency rooms.

How Long Does it Take to Diagnose Appendicitis? Time Point Process Mapping in the Emergency Department

OBJECTIVES

Appendicitis is the most common surgical emergency encountered in the pediatric emergency department (ED). We analyzed the time course of children evaluated for suspected appendicitis in relation to implementation of a risk-stratified ultrasound scoring system and structured reporting template (Appy-Score).

METHODS

In July 2013, a 6-level ultrasound (US)-based appendicitis scoring system was developed and implemented. The records of children (age ≤18 years) who underwent limited abdominal US exams for suspected appendicitis at a large academic pediatric ED were reviewed retrospectively. Time periods evaluated were from January 1 to April 1, 2013 (before implementation of the US scoring system, "PRE") and July 1 to October 1, 2013 (after implementation of the US scoring system, "POST"). Times are presented as medians with interquartile range.

RESULTS

A total of 926 children were included (median age, 9.5 years [range, 0.1-18 years]; 49% female). Four hundred eighty-one patients were evaluated PRE and 445 POST. When comparing the 2 groups, there were no differences in the PRE and POST periods with regard to time from US ordered to first read (102 vs 112 minutes, P = 0.30), US ordered to disposition (215 vs 208 minutes, P = 0.40) and operating room posting (121 vs 122 minutes, P = 0.59), and overall ED stay (329 vs 333 minutes, P = 0.39).

CONCLUSIONS

The development of a radiographic appendicitis score, although allowing for a standardized reporting method, did not significantly alter the ED process flow for evaluation of appendicitis. This reflects the complexities in ED throughput and reveals the need for additional factors to change to improve patient flow.

Severe neonatal hyperbilirubinaemia is frequently associated with long hospitalisation for emergency care in Nigeria

AIM

This study investigated the frequency and predictors of a long hospital stay (LHS) for severe neonatal hyperbilirubinaemia in Nigeria.

METHODS

Length of stay (LOS) for severe hyperbilirubinaemia was examined among neonates consecutively admitted to the emergency department of a children's hospital in Lagos from January 2013 to December 2014. The median LOS was used as the cut-off for LHS. Multivariate logistic regression determined the independent predictors of LHS based on demographic and clinical factors significantly associated with the log-transformed LOS in the bivariate analyses.

RESULTS

We enrolled 622 hyperbilirubinaemic infants with a median age of four days (interquartile range 2-6 days) and 276 (44.4%) had LHS based on the median LOS of five days. Regardless of their birth place, infants were significantly more likely to have LHS if they were admitted in the first two days of life (p = 0.008) - especially with birth asphyxia - or had acute bilirubin encephalopathy (p = 0.001) and required one (p = 0.020) or repeat (p = 0.022) exchange transfusions. Infants who required repeat exchange transfusions had the highest odds for LHS (odds ratio 4.98, 95% confidence interval 1.26-19.76).

CONCLUSION

Severe hyperbilirubinaemia was frequently associated with long hospitalisation in Nigeria, especially if neonates had birth asphyxia or required exchange transfusions.

Multiple performance measures are needed to evaluate triage systems in the emergency department

OBJECTIVES

Emergency department triage systems can be considered prediction rules with an ordinal outcome, where different directions of misclassification have different clinical consequences. We evaluated strategies to compare the performance of triage systems and aimed to propose a set of performance measures that should be used in future studies.

STUDY DESIGN AND SETTING

We identified performance measures based on literature review and expert knowledge. Their properties are illustrated in a case study evaluating two triage modifications in a cohort of 14,485 pediatric emergency department visits. Strengths and weaknesses of the performance measures were systematically appraised.

RESULTS

Commonly reported performance measures are measures of statistical association (34/60 studies) and diagnostic accuracy (17/60 studies). The case study illustrates that none of the performance measures fulfills all criteria for triage evaluation. Decision curves are the performance measures with the most attractive features but require dichotomization. In addition, paired diagnostic accuracy measures can be recommended for dichotomized analysis, and the triage-weighted kappa and Nagelkerke's R² for ordinal analyses. Other performance measures provide limited additional information.

CONCLUSION

When comparing modifications of triage systems, decision curves and diagnostic accuracy measures should be used in a dichotomized analysis, and the triage-weighted kappa and Nagelkerke's R² in an ordinal approach.

Emergency Department Flow Measures for Adult and Pediatric Patients in British Columbia and Ontario: A Retrospective, Repeated Cross-Sectional Study

BACKGROUND

Evidence suggests emergency department (ED) overcrowding is associated with poor health outcomes. Children comprise 20-25% of general ED visits, yet few studies have examined the differential impact of ED overcrowding on pediatric and adult populations.

OBJECTIVE

The primary objective of this study was to compare flow measures, such as wait time to see a physician, length of stay (LOS), and rate of patients leaving without being seen by a physician (LWBS) between adults and children in British Columbia and Ontario, clustered by province, and then stratified by acuity level during the study period.

METHODS

We conducted a retrospective, repeated cross-sectional study using administrative data from all community EDs in Ontario and 10 EDs in the Vancouver Lower Mainland, British Columbia. Visits from January 1, 2008 and December 31, 2012 were included.

RESULTS

Visit volumes increased 13.9% per year in British Columbia and 2.2% per year in Ontario, with a more pronounced rise in adult visits. Both groups displayed a shift toward higher-acuity presentations. Adults spent more time in the ED compared to children (36 to 53 min longer), and were more likely to be admitted. Children consistently spent a greater portion of their visit awaiting assessment compared to adults.

CONCLUSIONS

In the context of system incentives to reduce overcrowding, ED LOS and the LWBS rate did not significantly change for either children or adults, despite increased visit volume and acuity. Our findings suggest that measures to improve patient flow might have provided EDs with the means to meet increased demands on departmental resources.

Return visits to the pediatric emergency department: A multicentre retrospective cohort study

Objective

Return visits to the emergency department (RTED) for the same clinical complaint occur in 2.7% to 8.1% of children presenting to pediatric emergency departments (PEDs). Most studies examining RTEDs have focused solely on PEDs and do not capture children returning to other local emergency departments (EDs). Our objective was to measure the frequency and characterize the directional pattern of RTED to any of 18 EDs serving a large geographic area for children initially evaluated at a PED.

Methods

We conducted a retrospective cohort study of all visits to a referral centre PED between August 2012 and August 2013. We compared demographic variables between children with and without an RTED, measures of flow and disposition outcomes between the initial (index) visit and RTED, and between RTED to the original PED versus to other EDs in the community.

Results

Among all PED visits, 7.6% had an RTED within 7 days, of which 13% were to a facility other than the original PED. Children with an RTED had higher acuity and longer length of stay on their index visit. They were also more likely to be admitted on a subsequent visit than the overall PED population. RTED to the original PED had a longer waiting time (WT), length of stay, and more frequently resulted in hospitalization than RTED to a general ED.

Conclusions

A significant proportion of RTED occur at a site other than where the original ED visit occurred. Examining RTED to and from only PEDs underestimates its burden on emergency health services.

Predicting return visits to the emergency department for pediatric patients: Applying supervised learning techniques to the Taiwan National Health Insurance Research Database

BACKGROUND AND OBJECTIVE

Return visits (RVs) to the emergency department (ED) consume medical resources and may represent a patient safety issue. The occurrence of unexpected RVs is considered a performance indicator for ED care quality. Because children are susceptible to medical errors and utilize considerable ED resources, knowing the factors that affect RVs in pediatric patients helps improve the quality of pediatric emergency care.

METHODS

We collected data on visits made by patients aged ≤18years to EDs from the National Health Insurance Research Database. The outcome of interest was a RV within 3days of the initial visit. Potential factors were categorized into demographics, medical history, features of ED visits, physician characteristics, hospital characteristics, and treatment-seeking behavior. A multivariate logistic regression was used to identify independent predictors of RVs. We compared the performance of various data mining techniques, including Naïve Bayes, classification and regression tree (CART), random forest, and logistic regression, in predicting RVs. Finally, we developed a decision tree to stratify the risk of RVs.

RESULTS

Of 125,940 visits, 6,282 (5.0%) were followed by a RV within 3 days. Predictors of RVs included younger age, higher acuity, intravenous fluid, more examination types, complete blood count, consultation, lower hospital level, hospitalization within one week before the initial visit, frequent ED visits in the past one year, and visits made in Spring or on Saturdays. Patients with allergic diseases and those underwent ultrasound examination were less likely to return. Decision tree models performed better in predicting RVs in terms of area under curve. The decision tree constructed using the CART technique showed that the number of ED visits in the past one year, diagnosis category, testing of complete blood count, and age were important discriminators of risk of RVs.

CONCLUSIONS

We identified several factors which are associated with RVs to the ED in pediatric patients. The knowledge of these factors may help assess risk of RVs in the ED and guide physicians to reevaluate and provide interventions to children belonging to the high risk groups before ED discharge.

Parameters affecting length of stay in a pediatric emergency department: a retrospective observational study

Prolonged emergency department (ED) length of stay (LOS) is used as a proxy for ED overcrowding and is associated with adverse outcomes of patients requiring therapy and reduced patient satisfaction. Our aim was to identify and quantify variables which affect ED-LOS. Patients admitted to the pediatric ED of a large regional Swiss hospital during a 1-year period were analyzed for LOS (in minutes). Predictor variables included patient-associated parameters (time of admission and discharge, ED occupancy, triage score, diagnosis, and demographic data) and external factors (weekday, time, and season). A total of 4885 visits were included in a multivariable logistic regression analysis. Median LOS was 124 min. The most important factors associated with prolonged LOS were physician referral (adjusted odds ratio [OR], 1.97; 95% confidence interval [CI], 1.47-2.62); morning admissions, especially before noon (OR, 1.92; 95% CI, 1.23-3.07); and gastrointestinal infections (OR, 1.38; 95% CI, 1.08-1.76). Upper airway infections (OR, 0.37; 95% CI, 0.27-0.49) and triage level 5 (OR, 0.18; 95% CI, 0.06-0.61) were inversely associated with ED-LOS. Together with ED occupancy, these factors did significantly contribute to log LOS in a stepwise backward multiple regression model (p < 0.001).

CONCLUSION

Several parameters are associated with prolonged ED-LOS. Notably, morning arrivals represent possible targets for strategies to reduce LOS. What is Known: • Prolonged length of stay (LOS) may affect care delivered to admitted patients in the emergency department (ED) and is well studied in the setting of adult patients with high acuity conditions. • Little is known about parameters which impact LOS in European pediatric EDs. What is New: • Several predictors of prolonged LOS could be identified in a European pediatric setting. • Our results indicate that prolonged LOS is associated with modifiable factors like morning and summer admission, which have the potential to be addressed by modification in staffing, infrastructure, and higher attention to faster processing.

Inter-rater reliability between nurses for a new paediatric triage system based primarily on vital parameters: the Paediatric Triage Instrument (PETI)

INTRODUCTION

The major paediatric triage systems are primarily based on flow charts involving signs and symptoms for orientation and subjective estimates of the patient's condition. In contrast, the 4-level Paediatric Triage Instrument (PETI) is primarily based on vital parameters and was developed exclusively for paediatric triage in patients with medical symptoms. The aim of this study was to assess the inter-rater reliability of this triage system in children when used by nurses.

METHODS

A design was employed in which triage was performed simultaneously and independently by a research nurse and an emergency department (ED) nurse using the PETI. All patients aged ≤12 years who presented at the ED with a medical symptom were considered eligible for participation.

RESULTS

The 89 participants exhibited a median age of 2 years and were triaged by 28 different nurses. The inter-rater reliability between nurses calculated with the quadratic-weighted κ was 0.78 (95% CI 0.67 to 0.89); the linear-weighted κ was 0.67 (95% CI 0.56 to 0.80) and the unweighted κ was 0.59 (95% CI 0.44 to 0.73). For the patients aged <1, 1-3 and >3 years, the quadratic-weighted κ values were 0.67 (95% CI 0.39 to 0.94), 0.86 (95% CI 0.75 to 0.97) and 0.73 (95% CI 0.49 to 0.97), respectively. The median triage duration was 6 min.

CONCLUSIONS

The PETI exhibited substantial reliability when used in children aged ≤12 years and almost perfect reliability among children aged 1-3 years. Moreover, rapid application of the PETI was demonstrated. This study has some limitations, including sample size and generalisability, but the PETI exhibited promise regarding reliability, and the next step could be either a larger reliability study or a validation study.

Emergency Department Return Visits Within a Large Geographic Area

BACKGROUND

Return visits to the emergency department (RTED) contribute to overcrowding and may be a quality of care indicator. Previous studies focused on factors predicting returns to and from the same center. Little is known about RTEDs across a range of community and specialty hospitals within a large geographic area.

OBJECTIVE

We sought to measure the frequency of pediatric RTEDs and describe their directional pattern across centers in a large catchment area.

METHODS

We conducted a multicenter, retrospective cross-sectional study of pediatric emergency visits in the Vancouver lower mainland within 1 year. Visits were linked across study sites, including one pediatric quaternary care referral center and 17 sites ranging from large regional centers to smaller community emergency departments (EDs). Returns were defined as subsequent visits to any site with a compatible diagnosis within 7 days of an index visit.

RESULTS

Among a total of 139,278 index ED visits by children, 12,133 (8.7% [95% confidence interval 8.6-8.9%]) were associated with 14,645 return visits to an ED. Three quarters of all index visits occurred at a general ED center, of which 8.9% had at least one RTED and 22% of these returns occurred at the pediatric ED (PED). Among PED index visits, 8.2% had at least one RTED and 13.6% of these returned to a general center. Overall, 38.9% of all RTEDs occurred at the PED. Multivariate regression did not identify any statistically significant association between ED crowding measures and likelihood of RTEDs.

CONCLUSIONS

Compared to single-center studies, this study linking hospitals within a large geographic area identified a higher proportion of RTEDs with a disproportionate burden on the PED.

Does Abnormal Laboratory Results Notification with the Short Message Service Shorten Length of Stay in the Pediatric Emergency Department Observation Unit?

BACKGROUND

A new age in communications began with the entry into use of cell phones and their applications. Cell phones and their various applications must be actively used in patient monitoring in the healthcare system.

INTRODUCTION

The purpose of this study was to determine the length of stay in the pediatric emergency department observation unit (PEDOU) based upon the notification of abnormal laboratory results (ALRs) via the short message service (SMS).

MATERIALS AND METHODS

Patients with ALRs notified through the SMS (April-May-June 2015: study period) were evaluated retrospectively, and those admitted to hospital after such notification were enrolled as the study group (SG). Patients presenting to the pediatric emergency department (April-May-June 2014: control period), whose ALRs were not notified through the SMS, and who were hospitalized for treatment, were enrolled as the control group (CG). Age, sex, length of stay in the PEDOU (min), admission diagnosis, and receiving department were recorded for both groups.

RESULTS

Number of patients monitored in the PEDOU was 8584 during the study period and 8507 during the control period (p = 0.27). Length of stay of patients monitored in the PEDOU during the control period (n = 8507) and study period (n = 8584) was 136.4 and 133.5 min, respectively (p = 0.92). One hundred forty-seven patients were enrolled as the SG and 154 as the CG. Length of stay in the PEDOU was 221.1 ± 86.9 (65-542) min in the CG and 154.8 ± 76.6 (15-442) min in the SG (p < 0.001, 95% confidence interval: 47.5-84.8).

CONCLUSIONS

Notification of ALRs through the SMS does not affect length of stay in the PEDOU. Use of this method reduces length of stay of patients who require more rapid hospitalization.

Changing paediatric emergency department model of care is associated with improvements in the National Emergency Access Target and a decrease in inpatient admissions

OBJECTIVE

To assess the impact on patient flow as noted by the National Emergency Access Target (NEAT), with the introduction of a new Paediatric ED (PEM ED) model of care.

METHODS

This longitudinal observational study was conducted at the Logan Hospital, a 344 bed public hospital in metropolitan Brisbane, which opened a physically separate, dedicated PEM ED on 14 October 2014, incorporating approximately 30% more staff, limited changes in processes and no changes in governance. De-identified data of the entire clientele from the ED Information System were compared 365 days before and after the opening of the PEM ED.

RESULTS

Although the number of children presenting to ED increased by 23% (pre 18 142, post 22 391), the median length of stay decreased substantially from 152 min to 138 min, resulting in a 7.75% rise in presentations that met the NEAT target (pre 77.41%, post 85.16%; P < 0.0001). Admission to the ED Short Stay Unit rose by 16.48% (pre 5.38%, post 21.86%; P < 0.0001), whereas final disposition to the inpatient paediatric unit fell by 2.30% (pre 11.43, post 9.13%; P < 0.0001). The clinical presentations were similar pre and post across age, sex, ethnicity, referral and arrival mode, Australasian Triage Scale category, presenting problem and discharge diagnosis.

CONCLUSION

NEAT times improved after changing the PEM ED model of care. Further studies may assist identifying which of the specific features within the new model are most effective for improving patient flow.

Evaluating the Impact of Clinical Decision Tools in Pediatric Acute Gastroenteritis: A Population-based Cohort Study

OBJECTIVE

Acute gastroenteritis (AGE) is a leading cause of pediatric emergency department (ED) visits. Despite evidence-based guidelines, variation in adherence exists. Clinical decision tools can enhance evidence-based care, but little is known about their use and effectiveness in pediatric AGE. This study sought to determine if the following tools-1) pathways/order sets, 2) medical directives for oral rehydration therapy (ORT) or ondansetron, and 3) printed discharge instructions-are associated with AGE admission and ED revisits.

METHODS

This was a retrospective population-based cohort study of all children 3 months-18 years with an AGE ED visit in Ontario, Canada, from 2008 to 2010, using linked survey and health administrative databases. Logistic regression models associating clinical decision tools (CDTs) with hospitalizations and revisits controlling for hospital and patient characteristics were employed.

RESULTS

Of the 57,921 patient visits during the study period, there were 2,401 hospitalizations (4.2%). A total of 55,520 patients were discharged from the ED, with 2,378 (4.3%) experiencing a 72-hour return visit. In adjusted models, none of the tools were significantly associated with admission. Medical directive for ORT was associated with lower return visit rates (adjusted odds ratio [aOR] = 0.86, 95% confidence interval [CI] = 0.79-0.94] and printed discharge instructions with higher return visits (aOR = 1.33, 95% CI = 1.08-1.65); pathways/order sets and medical directives for ondansetron had no association.

CONCLUSIONS

Admissions in children with AGE are not associated with the presence of CDTs. While ORT medical directives are associated with lower ED revisits, printed discharge instructions have the opposite effect. The simple presence/absence of decision support tools does not guarantee improved clinical outcomes.

An Analysis of Intravenous Catheter Placement Among Patients in a Pediatric Emergency Department

OBJECTIVES

Pediatric emergency departments (PED) are overcrowded and at times inefficient with malaligned resources, especially regarding the use of intravenous (IV) catheters which are placed frequently, yet may be underused. This study seeks to determine which pediatric patients are more likely to need IV access in a PED.

METHODS

This retrospective study examined patients 3 days to 21 years seen in a tertiary PED from January 1, 2013, to February 28, 2013, who were triaged using the Emergency Severity Index, levels 1 to 3. Extracted data included age, chief complaints, chronic medical conditions, final diagnoses, evidence of venipuncture, and IV placement and usage. Patients were excluded if they entered the PED with an IV or central venous catheter, were older than 21 years, or had charts with missing data.

RESULTS

Four thousand three hundred twenty-two patients were initially evaluated, and 122 patients were excluded. Mean age of the patients was 6.2 years (SD = 5.65), most common triage was level 3 (urgent), and the majority of patients (n = 2898, 69.0%) did not have a chronic medical condition. Five hundred forty-five (13%) had IVs placed, and of those, 152 (27.9%) had IVs placed and not used. Patients triaged as critical or emergent, patients older than 10 years, and those with a gastrointestinal chief complaint and chronic medical conditions involving hematology, oncology/immunology, or endocrinology were most likely to have an IV placed and used.

CONCLUSIONS

Patients with higher acuities, specified systemic complaints, certain chronic medical conditions, and patients older than 10 years are more likely to need an IV.

Variation and Trends in Charges for Pediatric Care in Massachusetts Emergency Departments, 2000-2011

OBJECTIVES

Emergency department (ED) utilization by children is common and growing more expensive. Tracking trends and variability in ED charges is essential for policymakers who strive to improve the efficiency of the health care system and for payers who prepare health care budget forecasts. Our objective was to examine trends and variability in ED charges for pediatric patients across Massachusetts.

METHODS

This was a comprehensive analysis of the statewide database containing all the visits of children aged 0 to 18 years evaluated in any of the state's EDs from 2000 to 2011, excluding patients with chronic medical conditions and those whose visits resulted in hospital admission. A validated system designed to specifically classify pediatric emergency patients into major diagnostic groups was used. Mean charges as well as interhospital variability of charges over time were examined for the most common diagnostic groups.

RESULTS

Seventy-six hospitals provided emergency care in Massachusetts during the study period, with 6,249,923 pediatric patients treated and discharged. Statewide charges significantly increased from 2000 until 2007/2008, before plateauing or decreasing through 2011. There was no evidence that interhospital variability changed over time. With the exception of academic teaching status, no hospital-level factors emerged as consistent predictors of charges.

CONCLUSIONS

Charges for common pediatric emergency conditions varied widely across Massachusetts EDs, and hospital-level factors by and large could not consistently explain the variability. Although a plateau (and in some cases decrease) of statewide pediatric emergency health care charges was observed after 2007, no evidence was found that interhospital variability decreased. These data may be useful in the ongoing effort to reform the economics of health care delivery systems.

C-Reactive Protein Bedside Testing in Febrile Children Lowers Length of Stay at the Emergency Department

BACKGROUND

C-Reactive protein (CRP) is an important diagnostic marker for serious bacterial infections in febrile children. C-Reactive protein bedside testing could potentially accelerate the diagnostic evaluation and shorten length of stay (LOS).

OBJECTIVE

The aim of the study was to study the effect of introducing CRP bedside testing on the LOS of febrile children at the emergency department (ED).

DESIGN AND INTERVENTION

A prospective observational study with a preimplementation cohort (2008) with traditional CRP testing and a postimplementation cohort (2009-2011) in which CRP bedside testing was introduced.

PATIENTS AND SETTING

All previously healthy children with fever, aged 1 month to 16 years, attending the ED of a university hospital were included; non-ill-appearing children with an upper airway infection were not eligible for CRP bedside testing.

ANALYSIS AND MAIN OUTCOME MEASURE

Multivariable linear regression and propensity score analyses were used to determine the effect of CRP bedside testing on the logarithmic transformation length of stay [(log)LOS].

RESULTS

The preimplementation cohort included 609 children of whom 286 (47%) had traditional CRP. The postimplementation cohort included the following 1330 children: 728 (55%) children had bedside CRP and 156 (12%) children had traditional CRP. Bedside CRP significantly lowered the median LOS of children in whom an additional diagnostic CRP test was performed, from 178 minutes (interquartile range, 135-232 minutes) to 148 minutes (interquartile range, 108-200 minutes) (30 minutes, 19% of total LOS). A significant reduction of 15% of the (log)LOS remained after adjusting for other determinants of (log)LOS; propensity score analysis showed a 16% reduction.

CONCLUSIONS

C-Reactive protein bedside testing substantially lowered the LOS of children with fever at the ED in whom an additional diagnostic CRP test was performed.

The Australian public's preferences for emergency care alternatives and the influence of the presenting context: a discrete choice experiment

OBJECTIVES

The current study seeks to quantify the Australian public's preferences for emergency care alternatives and determine if preferences differ depending on presenting circumstances.

SETTING

Increasing presentations to emergency departments have led to overcrowding, long waiting times and suboptimal health system performance. Accordingly, new service models involving the provision of care in alternative settings and delivered by other practitioners continue to be developed.

PARTICIPANTS

A stratified sample of Australian adults (n=1838), 1382 from Queensland and 456 from South Australia, completed the survey. This included 951 females and 887 males from the 2045 people who met the screening criteria out of the 4354 people who accepted the survey invitation.

INTERVENTIONS

A discrete choice experiment was used to elicit preferences in the context of one of four hypothetical scenarios: a possible concussion, a rash/asthma-related problem involving oneself or one's child and an anxiety-related presentation. Mixed logit regression was used to analyse the dependent variable choice and identify the relative importance of care attributes and the propensity to access care in each context.

RESULTS

Results indicated a preference for treatment by an emergency physician in hospital for possible concussion and treatment by a doctor in ambulatory settings for rash/asthma-related and anxiety-related problems. Participants were consistently willing to wait longer before making trade-offs in the context of the rash/asthma-related scenario compared with when the same problem affected their child. Results suggest a clear preference for lower costs, shorter wait times and strong emphasis on quality care; however, significant preference heterogeneity was observed.

CONCLUSIONS

This study has increased awareness that the public's emergency care choices will differ depending on the presenting context. It has further demonstrated the importance of service quality as a determinant of healthcare choices. The findings have also provided insights into the Australian public's reactions to emergency care reforms.

Best practices for improving flow and care of pediatric patients in the emergency department

This report provides a summary of best practices for improving flow, reducing waiting times, and improving the quality of care of pediatric patients in the emergency department.

Hospital bed occupancy for rotavirus and all cause acute gastroenteritis in two Finnish hospitals before and after the implementation of the national rotavirus vaccination program with RotaTeq®

Background

Vaccination-impact studies of the live-attenuated pentavalent oral vaccine Rotateq® have demonstrated that the burden of rotavirus gastroenteritis has been reduced significantly after the introduction of RotaTeq® vaccination, but less is known about the benefit of this vaccination on hospital overcrowding.

Methods

As part of an observational surveillance conducted during the RV seasons 2000/2001 to 2011/2012, we analysed hospital discharge data collected retrospectively from two Finnish hospitals (Oulu and Tampere), concerning ICD 10 codes A00-09 (acute gastroenteritis, AGE) and A08.0 (rotaviral acute gastroenteritis RV AGE). We estimated the reduction in the number of beds occupied and analysed the bed occupancy rate, for RV AGE and all cause AGE, among 0–16 year-old children, before and after the implementation of the RV immunisation program.

Results

The rate of bed days occupied for RV AGE was reduced by 86% (95% CI 66%-94%) in Tampere and 79% (95% CI 47%-92%) in Oulu after RV vaccination implementation. For all cause AGE, reduction was 50% (95% CI 29% to 65%) in Tampere and 70% (95% CI 58% to 79%) in Oulu. Results were similar among 0–2 year-old children. This effect was also observed on overcrowding in both hospitals, with a bed occupancy rate for all cause AGE >25% in only 1% of the time in Tampere and 9% in Oulu after the implementation of the immunisation program, compared to 13% and 48% in the pre-vaccination period respectively. After extrapolation to the whole country, the annual number of prevented hospitalizations for all cause AGE in the post-vaccination period in Finland was estimated at 1,646 and 2,303 admissions for 0–2 and 0–16 year-old children respectively.

Conclusions

This study demonstrated that universal RV vaccination is associated with a clear decrease in the number of bed days and occupancy rates for RV AGE and all cause AGE. Positive consequences include increase in quality of care and a better healthcare management during winter epidemics.

C-reactive protein, procalcitonin and the lab-score for detecting serious bacterial infections in febrile children at the emergency department: a prospective observational study

BACKGROUND

C-reactive protein (CRP) and procalcitonin (PCT) are useful diagnostic tools to estimate the risk of serious bacterial infection (SBI) in febrile children at the emergency department (ED). The Lab-score combines these 2 biomarkers with urinalysis in an easy to use validated model. Kinetics of inflammatory markers suggests a differentiating role of duration of disease.

AIM

: Appraisal of the diagnostic role of CRP and PCT in febrile children at risk of SBI, determining the differentiating value of duration of fever, and validating and updating the Lab-score.

METHODS

In this prospective observational study previously healthy children with fever, 1 month to 16 years of age, attending the EDs of a university hospital and a teaching hospital (Rotterdam, the Netherlands) between 2009 and 2012 were included. Standardized information on clinical signs and symptoms, CRP, PCT and urinalysis were collected prospectively. Logistic multivariable regression analysis was used to assess diagnostic performance. The original Lab-score included CRP, PCT and urinalysis and the total score ranged 0-9 points.

RESULTS

One thousand eighty-four children were included, median age was 1.6 years (interquartile range: 0.8-3.5), 170 children (16%) had SBI. CRP [receiver operating characteristic (ROC)-area 0.77 (95% confidence interval [CI]: 0.69-0.85)] and PCT [ROC-area 0.75 (95% CI: 0.67-0.83)] were both strong predictors of SBI. Duration of fever had no added diagnostic value to CRP and PCT. The Lab-score performed well [ROC area 0.79 (95% CI: 0.72-0.87)], but threshold values performed similar to often used cutoffs of single biomarkers. An updated Lab-score improved only moderately [ROC area 0.83 (95% CI: 0.76-0.90)]. PCT did not alter post-test probabilities for SBI substantially in patients with low (<20 mg/L) or elevated CRP (≥ 100 mg/L) levels (67% of population).

CONCLUSION

CRP and PCT were both strong predictors of SBI. The original and updated Lab-score performed well, but thresholds values lacked diagnostic value for ruling out SBI. Depending on clinical risk thresholds, diagnostic testing can be limited to CRP or PCT, rather than both, in many febrile children.

Frequent pediatric emergency department use in infancy and early childhood

OBJECTIVE

To define the threshold and population factors associated with pediatric emergency department (PED) use above the norm during the first 36 months of life.

METHODS

We conducted a cross-sectional study of children born between 2003 and 2006, treated in a single PED within the first 36 months of life. Exclusion criteria included out-of-county residence or history of abuse or neglect. The primary outcome, frequent PED use, was defined by the 90th percentile for PED visits per patient. Multivariate analysis was used to identify factors associated with frequent PED use.

RESULTS

A total of 41,912 visits occurred for 16,664 patients during the study. Pediatric ED use skewed heavily toward less than 2 visits per patient (median, 2; range, 1-39; interquartile range, 2). The threshold for frequent PED use was 5 or more visits per patient and occurred for 14% (95% confidence interval [95% CI], 13%-15%) of patients. Most visits were coded with low acuity International Classifications of Diseases, 9th Revision, Clinical Modification codes. The following factors were strongly associated with frequent PED use: lack of primary care physician (odds ratio [OR], 6.03; 95% CI, 5.39%-6.80%; P < 0.0001), non private insurance (OR, 3.64; 95% CI, 2.99%-4.46%; P<0.0001), and history of inpatient admission (OR, 3.09; 95% CI, 1.66%-2.24%; P < 0.0001). Leaving without being seen, black race, Hispanic ethnicity, and residence in a poverty-associated zip code were also significantly associated, but less strongly predictive of, frequent PED use.

CONCLUSIONS

The threshold for frequent PED use was more than 5 visits per patient within the first 36 months of life. Further study is needed to better define this population and develop targeted interventions to ensure care provision occurs in the ideal setting.

A computerized child passenger safety screening program in the emergency department

OBJECTIVES

The emergency department (ED) can be an effective site for pediatric injury prevention initiatives, including child passenger safety. The objectives of this study were to evaluate the implementation of an ED child passenger safety program and to analyze the effectiveness of a computerized screening tool to identify car seat-related needs for children younger than 8 years.

METHODS

An ED-based group developed a child passenger safety program including (1) a computerized screening tool to assess the use of car seats in children younger than 8 years; (2) child passenger safety education, including state law; and (3) distribution of appropriate car seats for patients discharged from the ED. In July 2011, the screening tool was added to the initial nursing assessment. In January 2012, nursing education was performed to increase compliance with screening. In April 2012, the tool was made a mandatory field in the computerized initial nursing assessment.

RESULTS

From August 1 to December 31, 2011, 17 % (2270/13,637) of eligible children had computerized screenings performed; 18 car seats were distributed. From January 15 to March 15, 2012, 32% (2017/6270) of eligible children were screened; 9 car seats were distributed. From March 16 to May 19, 2012, 56% (3381/6063) were screened; 22 car seats were distributed. Screenings increased further from May 20 to July 25, 2012, with 87% (5077/5827) completed; 31 car seats were distributed.

CONCLUSIONS

A child passenger safety program can be successfully implemented in the ED. A computerized nursing screening tool increases compliance with screening and providing needed car seats.

The use of a kiosk-model bilingual self-triage system in the pediatric emergency department

BACKGROUND

Streamlining the triage process is the key in improving emergency department (ED) workflow. Our objective was to determine if parents of pediatric ED patients in, low-literacy, inner-city hospital, who used the audio-assisted bilingual (English/Spanish) self-triage kiosk, were able to enter their child's medical history data using a touch screen panel with greater speed and accuracy than routine nurse-initiated triage.

METHODS

Parent/child dyads visiting the pediatric ED for nonurgent conditions (February to April 2012) were randomized prospectively to self-triage kiosk group (n = 200) and standard nurse triage group (n = 200). Both groups underwent routine nurse-initiated triage that included verbal elicitation of basic medical history and manual entry into patients' electronic medical records.

RESULTS

The kiosk user was a parent in 88.5% of the cases, a patient (range, 11-17 years) in 9.5% of the cases, and a proxy user (sibling or friend) in 2% of the cases. Language choice for kiosk use was equally distributed (English vs Spanish, 50.5% vs 49.5%). The mean (SD) time to enter medical history data by the kiosk group was significantly shorter than the standard nurse triage group (94.38 [38.61] vs 126.72 [62.61] seconds; P < 0.001). Significant inverse relationship was observed between parent education level and kiosk usage time (r = -0.26; P < 0.001). The mean inaccuracies were significantly lower for kiosk group (P < 0.05) in areas of medical, medication and immunization histories, and total discrepancy score.

CONCLUSIONS

Kiosk triage enabled users to enter basic medical triage history data quickly and accurately in an ED setting with future potential for its wider use in improving ED workflow efficiency.

Emergency department crowding and time to antibiotic administration in febrile infants

Introduction:

Early antibiotic administration is recommended in newborns presenting with febrile illness to emergency departments (ED) to avert the sequelae of serious bacterial infection. Although ED crowding has been associated with delays in antibiotic administration in a dedicated pediatric ED, the majority of children that receive emergency medical care in the United States present to EDs that treat both adult and pediatric emergencies. The purpose of this study was to examine the relationship between time to antibiotic administration in febrile newborns and crowding in a general ED serving both an adult and pediatric population.

Methods:

We conducted a retrospective chart review of 159 newborns presenting to a general ED between 2005 and 2011 and analyzed the association between time to antibiotic administration and ED occupancy rate at the time of, prior to, and following infant presentation to the ED.

Results:

We observed delayed and variable time to antibiotic administration and found no association between time to antibiotic administration and occupancy rate prior to, at the time of, or following infant presentation (p>0.05). ED time to antibiotic administration was not associated with hospital length of stay, and there was no inpatient mortality.

Conclusion:

Delayed and highly variable time to antibiotic treatment in febrile newborns was common but unrelated to ED crowding in the general ED study site. Guidelines for time to antibiotic administration in this population may reduce variability in ED practice patterns.

Emergency department conditions associated with the number of patients who leave a pediatric emergency department before physician assessment

OBJECTIVES

As emergency department (ED) waiting times and volumes increase, substantial numbers of patients leave without being seen (LWBS) by a physician. The objective of this study was to identify ED conditions reflecting patient input, throughput, and output associated with the number of patients who LWBS in a pediatric setting.

METHODS

This study was a retrospective, descriptive study using data from 1 urban, tertiary care pediatric ED. The study population consisted of all patient visits to the ED from April 2005 to March 2007. Multivariate Poisson regression analyses were used to examine the impact of the timing of patient arrival and ED conditions including patient acuity, volume, and waiting times on the number of patients who LWBS.

RESULTS

During the study period, there were 138,361 patient visits corresponding to 2190 consecutive shifts; 11,055 patients (8%) left without being seen by a physician.In the multivariate analysis, the throughput variables, time from triage to physician assessment (rate ratio, 2.11; 95% confidence interval, 2.01-2.21), and time from registration to triage (rate ratio, 1.55; 95% confidence interval, 1.25-1.90) had the largest association with the number of patients who LWBS.

CONCLUSIONS

In the study ED, throughput variables played a more important role than input or output variables on the number of patients who LWBS. This finding, which contrasts with a work done previously in an ED serving primarily adults, highlights the importance of pediatric specific research on the impacts of increasing ED waiting times and volumes.

Effect of the duration of emergency department observation on computed tomography use in children with minor blunt head trauma

STUDY OBJECTIVE

We determine the effect of the duration of emergency department (ED) observation on computed tomography (CT) rate for children with minor blunt head trauma.

METHODS

We performed a prospective cohort study of children with blunt head trauma and a Glasgow Coma Scale score greater than 14. We defined time from injury as the time from head injury to initial physician (emergency attending physician or fellow) assessment. For children who were observed in the ED before CT decisionmaking, we defined ED observation time as time from initial physician assessment to the decision whether to obtain a CT. After adjusting for time from injury, patient age, sex, physician type, and study month, we measured the effect of ED observation time on CT rate in each of the 3 Pediatric Emergency Care Applied Research Network Traumatic Brain Injury risk groups.

RESULTS

Of the 1,605 eligible patients, we enrolled 1,381 (86%). Of the enrolled patients, 676 (49%) were observed in the ED and 272 (20%) had a CT performed. After adjustment, every hour of ED observation time was associated with a decrease in CT rate for children in all 3 traumatic brain injury risk groups: high risk (adjusted odds ratio [OR] 0.11; 95% confidence interval [CI] 0.05 to 0.24), intermediate risk (adjusted OR 0.28; 95% CI 0.21 to 0.36), and low risk (adjusted OR 0.47; 95% CI 0.31 to 0.73). All 8 children with a significant traumatic brain injury had an immediate CT.

CONCLUSION

For children with minor blunt head trauma, ED observation time was associated with a time-dependent reduction in cranial CT rate, with no delay in the diagnosis of a significant traumatic brain injury.

[Paediatric emergency triage in Spanish primary care using mobile phones. Analysis of a model in a health area]

OBJECTIVES

To conduct a pilot study of telephone consultation in the paediatric population of an urban health centre. To evaluate the telephone consultation as an effective tool when it comes to exercising prior triage of patients requiring urgent attention.

MATERIAL AND METHODS

The study was conducted in two phases. In the first, data were collected from all calls received for six months. In a second phase, we conducted a telephone intervention study to analyse what a random sample of users remembered of the care provided. All those who requested a telephone consultation were included in the study. Demographic, social-welfare, epidemiological, and clinical features, of each patient were recorded. Data were processed using a statistical package SPSS version 17.0 for Windows.

RESULTS

There were 439 telephone inquiries in our pilot project, of which 35.1% were attended by residents, 36% by paediatricians, and 28.9% by paediatric nurses. There were more telephone calls in the afternoons and on weekends. Patients less than or equal to 2 years accounted for 57.9% of cases handled, and there were no differences between sexes. The most frequent reasons for consultation were gastrointestinal symptoms, fever and respiratory problems. The health problem was resolved in 85.8% of cases, requiring only home care instructions, and only 13.3% of children were referred to emergency services. We obtained a mean score of satisfaction of 9.2.

CONCLUSIONS

The pilot project had a high level of satisfaction and resolution, demonstrating cost savings by reducing 55% of face to face visits, with a saving of 35.2 euros per telephone consultation. A teleconsultation model for dealing with emergencies in primary care by telephone would be comparable to a practice staffed by trained paediatric nurses.

Boarding admitted children in the emergency department impacts inpatient outcomes

OBJECTIVE

This study aimed to assess the relationship between boarding of admitted children in the emergency department (ED) and cost, inpatient length of stay (LOS), mortality, and readmission.

METHODS

This was a retrospective study of 1,792 pediatric inpatients admitted through the ED and discharged from the hospital between February 20, 2007 and June 30, 2008 at a major teaching hospital with an annual ED volume of 40,000 adult and pediatric patients.The main predictor variable was boarding time (time from admission decision to departure for an inpatient bed, in hours). Covariates were patient age, payer group, times of ED and inpatient bed arrival, ED triage acuity, type of inpatient service, intensive care unit admission, surgery, and severity of inpatient illness. The main outcome measures, cost (dollars) and inpatient LOS (hours), were log-transformed and analyzed using linear regressions. Secondary outcomes, mortality and readmission to the hospital within 72 hours of discharge, were analyzed using logistic regression.

RESULTS

Mean ED LOS for admitted patients was 9.0 hours. Mean boarding time was 5.1 hours. Mean cost and inpatient LOS were $9893 and 147 hours, respectively. In general, boarding time was associated with cost (P < 0.001) and inpatient LOS (P = 0.01) but not with mortality or readmission. Longer boarding times were associated with greater inpatient LOS especially among patients triaged as low acuity (P = 0.008). In addition, longer boarding times were associated with greater probability of being readmitted among patients on surgical services (P = 0.01).

CONCLUSIONS

Among low-acuity and surgical patients, longer boarding times were associated with longer inpatient LOS and more readmissions, respectively.

Effectiveness of multifunction paediatric short-stay units: a French multicentre study

AIM

To describe the characteristics of the activities of multifunction paediatric 'short-stay units' (SSU) including observation unit (OU), medical assessment and planning unit (MAPU) and holding unit (HU), to evaluate their effectiveness and to explore predictors of inappropriate admissions for OU patients.

METHODS

Admissions to nine French paediatric SSUs were analysed. The main outcome measures were SSU length of stay with associated outcome for all patients and appropriate admission rate for OU patients.

RESULTS

Of 1084 patients included in the study, 66% were OU patients (n = 718), 21% MAPU patients (n = 225) and 13% HU patients (n = 141). The OU patients constituted the majority of the SSU admissions. The appropriate OU admission rates ranged from 52% to 86%. Head trauma and seizure were the conditions with the highest appropriate OU admission rates (82%). Age <1 year, and need for IV fluids or medications, CT-Scan or MRI and cardiorespiratory monitoring were associated with an increased risk of inappropriate OU admission. Eighteen per cent of the MAPU patients and 5% of the HU patients were discharged home within 24 h.

CONCLUSION

By providing extended and easily available facilities for diagnostics and early treatment for a wide range of sick children, the French paediatric SSU is an effective model for 'observation medicine' in emergency department-managed units. The experience and principles may be applicable to similar units in other health care systems.

Emergency department crowding and analgesic delay in pediatric sickle cell pain crises

OBJECTIVES

The objectives of the study were to test the impact of emergency department (ED) crowding and to identify factors associated with delay in analgesic administration in pediatric sickle cell pain crises.

METHODS

This was a cross-sectional study at a children's hospital ED. Data included demographics, clinical features, triage acuity, 10-level triage pain score, and arrival-to-analgesic-administration time. Emergency department census was the crowding measure assigned to each patient at arrival. Severe pain was a triage pain score of more than 7. Delays of more than 60 minutes from arrival to analgesic administration represented poor care. Logistic regression tested the effect of ED census on time to analgesic administration after adjusting for patient demographic and clinical characteristics.

RESULTS

From 243 encounters (161 patients), we excluded 11 visits (missing charts [n = 7], no pain at triage [n = 3], analgesic refusal [n = 1]). Final analysis involved 232 encounters (150 patients). Most were black with hemoglobin SS. Median age was 12 years. Mean ED census was 57. Median time from arrival to analgesic administration was 90 minutes. Analgesics were administered in less than 60 minutes in 70 encounters (30%). Most delays occurred after triage. Univariate analysis revealed that analgesic administration within 60 minutes of arrival was associated with severe pain at triage. After controlling for other factors, analgesic administration was significantly delayed during higher ED census and significantly earlier for young children and those with severe pain at triage. The time to analgesic administration from arrival significantly increased per increasing quartile of ED census (P = 0.0009).

CONCLUSION

Emergency department crowding is associated with delay in analgesic administration in pediatric patients with sickle cell pain crisis.

Development of a screening tool for pediatric sexual assault may reduce emergency-department visits

OBJECTIVE

To define the characteristics of a novel screening tool used to identify which prepubertal children should potentially receive an initial evaluation for alleged sexual assault in a nonemergent setting.

METHODS

Electronic medical records were retrospectively reviewed from 2007 to 2008. Visits with a chief complaint or diagnosis of alleged sexual assault for patients aged 12 years or younger were identified. Complete records, those with no evaluation before pediatric emergency-department arrival, and those with child advocacy center follow-up were included. Records were reviewed to answer the following: (1) Did the incident occur in the past 72 hours, and was there oral or genital to genital/anal contact? (2) Was genital or rectal pain, bleeding, discharge, or injury present? (3) Was there concern for the child's safety? (4) Was an unrelated emergency medical condition present? An affirmative response to any of the questions was considered a positive screen (warranting immediate evaluation); all others were considered negative screens. Those who had positive physical examination findings of anogenital trauma or infection, a change in custody, or an emergency medical condition were defined as high risk (having a positive outcome).

RESULTS

A total of 163 cases met study criteria; 90 of 163 (55%) patients had positive screens and 73 of 163 (45%) had negative screens. No patients with negative screens were classified as high risk. The screening tool has sensitivity of 100% (95% confidence interval: 93.5-100.0).

CONCLUSIONS

This screening tool may be effective for determining which children do not require emergency-department evaluation for alleged sexual assault.

Evaluating the impact of the electronic health record on patient flow in a pediatric emergency department

BACKGROUND

There is little data on the effect of the EHR on emergency department (ED) efficiency.

OBJECTIVE

1) to quantify the effect of the EHR on patient flow in an academic pediatric ED. 2) to analyze the effects of patient census, boarding time, staffing hours, and acuity on the mean daily ED length-of-stay (LOS) and triage-to-provider time.

METHODS

ED performance was compared before and after the implementation of an EHR in May 2008. Six month intervals were used with a 5 month period of adjustment between the pre- and post-EHR intervals. 34791 patient visits met inclusion criteria. Multiple linear regression was used to evaluate the LOS and triage-to-provider time as influenced by internal and external variables affecting the ED.

RESULTS

Daily patient census increased by 5.8% (p<0.01) without a change in rate of ED admissions. Nursing and practitioner hours increased by 19.7% and 16.1%, respectively because of the increased census and a perceived slowing associated with the EHR. Following the implementation, LOS remained unchanged while triage-to-provider time increased by 5 minutes per patient (p<0.05). Factors that independently affected both LOS and triage-to-provider time included census, acuity, and practitioner hours (p<0.05). When controlling for these independent variables, the use of an EHR did not affect either outcome variable (p=0.251, 0.074 respectively). However, patient flow was worsened with the EHR during days of extremely high patient census.

CONCLUSION

An ED-EHR was associated with a modest increase in time to see a medical provider but was not associated with a change in overall LOS. When controlling for factors including patient volume, acuity, and staffing, the EHR did not independently affect ED patient flow. The EHR may have a more profound impact on ED performance during periods of extremely high census.

Factors associated with prolonged emergency department length of stay for admitted children

OBJECTIVE

To estimate the prevalence of and to identify factors associated with prolonged emergency department length-of-stay (ED-LOS) for admitted children.

METHODS

Data were from the 2001-2006 National Hospital Ambulatory Medical Care Survey. The primary outcome was prolonged ED-LOS (defined as total ED time >8 hours) among admitted children. Predictor variables included patient-level (eg, demographics including race/ethnicity, triage score, diagnosis, and admission to inpatient bed vs intensive care unit), physician-level (intern/resident vs attending physician), and system-level (eg, region, metropolitan area, ED and hospital type, time and season, and diagnostic and therapeutic procedures) factors. Multivariable logistic regression was performed to identify independent predictors of prolonged ED-LOS.

RESULTS

Median ED-LOS for admitted children was 3.7 hours. Thirteen percent of pediatric patients admitted from the ED experienced prolonged ED-LOS. Factors associated with prolonged ED-LOS for admitted children were Hispanic ethnicity (odds ratio [OR], 1.76; 95% confidence interval [95% CI], 1.10-2.81), ED arrival between midnight and 8 a.m. (OR, 2.80; 95% CI, 1.87-4.20), winter season (January-March: OR, 1.81; 95% CI, 1.20-2.74), computed tomography scan or magnetic resonance imaging (OR, 1.65; 95% CI, 1.05-2.58), and intravenous fluids or medications (OR, 1.81; 95% CI, 1.10-2.97). Children requiring ICU admissions (OR, 0.29; 95% CI, 0.11-0.77) or receiving pulse oximetry in the ED (OR, 0.52; 95% CI, 0.34-0.81) had a lower risk of experiencing prolonged ED-LOS.

CONCLUSIONS

We found that prolonged ED-LOS occurs frequently for admitted pediatric patients and is associated with Hispanic ethnicity, presentation during winter season, and early morning arrival. Potential strategies to reduce ED-LOS include improved availability of interpreter services and enhanced staffing and additional inpatient bed availability during winter season and overnight hours.

The treatment of pediatric gastroenteritis: a comparative analysis of pediatric emergency physicians' practice patterns

OBJECTIVES

Acute gastroenteritis is a very common emergency department (ED) diagnosis accounting for greater than 1.5 million outpatient visits and 200,000 hospitalizations annually among children in the United States. Although guidelines exist to assist clinicians, they do not clearly address topics for which evidence is new or limited, including the use of antiemetic agents, probiotics, and intravenous (IV) fluid rehydration regimens. This study sought to describe the ED treatments administered to children with acute gastroenteritis and to compare management between Canadian and U.S. physicians practicing pediatric emergency medicine (PEM).

METHODS

Members of PEM research networks located in Canada and the United States were invited to participate in a cross-sectional, Internet-based survey. Participants were included if they are attending physicians and provide care to patients <18 years of age in an ED.

RESULTS

In total, 235 of 339 (73%) eligible individuals responded. A total of 103 of 136 Canadian physicians (76%) report initiating oral rehydration therapy (ORT) in children with moderate dehydration, compared with 44 of 94 (47%) of their U.S. colleagues (p<0.001). The latter more often administer antiemetic agents to children with vomiting (67% vs. 45%; p=0.001). American physicians administer larger IV fluid bolus volumes (p<0.001) and over shorter time periods (p=0.001) and repeat the fluid boluses more frequently (p<0.001). Probiotics are routinely recommended by only 35 of 230 respondents (15%).

CONCLUSIONS

The treatment of pediatric gastroenteritis varies by geographic location and differs significantly between Canadian and American PEM physicians. Oral rehydration continues to be underused, particularly in the United States. Probiotic use remains uncommon, while ondansetron administration has become routine. Children frequently receive IV rehydration, with the rate and volume administered being greater in the United States.

Feasibility of screening patients with nonpsychiatric complaints for suicide risk in a pediatric emergency department: a good time to talk?

OBJECTIVE

Screening children for suicide risk when they present to the emergency department (ED) with nonpsychiatric complaints could lead to better identification and treatment of high-risk youth. Before suicide screening protocols can be implemented for nonpsychiatric patients in pediatric EDs, it is essential to determine whether such efforts are feasible.

METHODS

As part of an instrument validation study, ED patients (10-21 years old) with both psychiatric and nonpsychiatric presenting complaints were recruited to take part in suicide screening. Clinically significant suicidal thoughts, as measured by the Suicidal Ideation Questionnaire, and suicidal behaviors were assessed, as well as patient opinions about suicide screening. Recruitment rates for the study as well as impact on length of stay were assessed.

RESULTS

Of the 266 patients and parents approached for the study, 159 (60%) agreed to participate. For patients entering the ED for nonpsychiatric reasons (n = 106), 5.7% (n = 6) reported previous suicidal behavior, and 5.7% (n = 6) reported clinically significant suicidal ideation. There were no significant differences for mean length of stay in the ED for nonpsychiatric patients with positive triggers and those who screened negative (means, 382 [SD, 198] and 393 [SD, 166] minutes, respectively; P = 0.80). Ninety-six percent of participants agreed that suicide screening should occur in the ED.

CONCLUSIONS

Suicide screening of nonpsychiatric patients in the ED is feasible in terms of acceptability to parents, prevalence of suicidal thoughts and behaviors, practicality to ED flow, and patient opinion. Future endeavors should address brief screening tools validated on nonpsychiatric populations.
