Admit Versus Discharge-A Cost Analysis of Infants 29 to 60 Days Old With Febrile Urinary Tract Infection at Low Risk for Bacteremia.

BACKGROUND: Ninety percent of infants 29 to 60 days old presenting to the emergency department with fever and urinary tract infection are admitted due to fear of concomitant bacteremia. Many of these infants are at low risk for bacteremia and can be safely discharged with no heightened risk of adverse events. This study sought to estimate the potential savings from outpatient management of low-risk infants. METHODS: A comparative cost analysis was performed using bacteremia probability estimates from a previously published prediction model. We estimated costs using a national pediatric database coupled with retrospective chart review of infants who presented to our emergency department between 2011 and 2015. RESULTS: The relative cost savings for the discharge strategy were $80,333 ($19,127 vs $99,460; 80% savings) for each patient with bacteremia and $257,073 per 100 patients overall. Similar savings were found for charges-$304,949 ($71,421 vs $376,371; 80%) for each patient with bacteremia and $975,838 per 100 patients. Our institutional reimbursements provided an estimated savings of $148,924 ($73,280 vs. $222,204; 67%) and $476,533 per 100 patients overall. CONCLUSIONS: The relative cost savings from discharging rather than admitting low-risk infants with febrile urinary tract infection were significant, even accounting for expenditures associated with the return emergency room visit of initially discharged bacteremic patients. These savings are achievable without an increase in adverse events. Similar outcomes were demonstrated for hospital charges and reimbursements, further strengthening these results. This study emphasizes how risk stratification in clinical decision-making can lead to substantial cost savings without compromising patient outcomes.

Secondary imaging for suspected appendicitis after equivocal ultrasound: time to disposition of MRI compared to CT.

PURPOSE: The purpose of this study was to compare MRI to CT as a secondary imaging modality for children age 5 years and older with suspected appendicitis after an equivocal abdominal ultrasound in terms of (1) the time to ED disposition decision, (2) surgery consultation rate, and (3) imaging test accuracy. METHODS: We retrospectively studied children with suspected appendicitis and equivocal ultrasound results who underwent MR or CT as secondary imaging in a pediatric emergency department over two-consecutive 9-month periods. No oral or intravenous contrast was utilized for MRI. No sedation was utilized for any modality. Time of disposition is the time to admission or discharge order. RESULTS: Twenty-five patients underwent CT and 30 underwent MRI, with no significant difference in the median time from ultrasound to disposition between the CT (5.9 h, IQR 4.5, 8.4) and the MRI (5.9 h, IQR 4.6, 6.9) groups (p = 0.65). Fifteen patients had appendicitis. Of the 40 negative or equivocal studies, surgery was consulted for 79% in the CT and 48% in the MRI group (odds ratio 4.12, 95% CI 1.02-16.67). Diagnostic accuracy was as follows: MRI: sensitivity of 90%, specificity of 97.1%, positive predictive value of 90%, and negative predictive value of 97.1%. Abdominal CT: sensitivity of 88%, specificity of 98.6%, positive predictive value of 95.7%, and negative predictive value of 95.8%. CONCLUSION: MRI is a feasible alternative to CT for secondary imaging in acute appendicitis for showing comparable ED throughput metrics and diagnostic accuracy, with added benefits of reduced radiation and avoidance of intravenous contrast.

Geographic Variation in the Use of Low-Acuity Pediatric Emergency Medical Services.

OBJECTIVE: The aim of this study was to examine geographic variation in pediatric low-acuity emergency medical services (EMS) use in Washington, DC. METHODS: This cross-sectional analysis of low-acuity EMS transports evaluated arrivals at 2 emergency departments and included 93% of pediatric transports in Washington, DC, during the study period. Low-acuity classification was defined as a triage emergency severity index of 4 or 5 not resulting in transfer, admission, or death. Logistic regression compared low-acuity visits arriving via EMS with all other low-acuity visits. Home zip code represented geographic location. Covariates included patient age, sex, race/ethnicity, hour of emergency department arrival, and insurance status. RESULTS: There were 45,454 low-acuity visits among children aged 0 to 17 years. Of these, 3304 (7.3%) arrived via EMS. The mean age was 5.6 (±5.0) years. Most were African American (84.3%) and had Medicaid insurance (87.3%). Geographic variation predicted EMS use. Adjusted odds ratios (ORs) of using EMS varied from 1.11 to 2.54 when compared with the lowest EMS use zip code. Odds of EMS use were higher among those with public insurance (adjusted OR [adj OR], 1.71; 95% confidence interval [CI], 1.46-2.00) and those with evening and overnight arrivals (evening arrival, adj OR of 1.65 and 95% CI of 1.47-1.86; overnight arrival, adj OR of 2.98 and 95% CI of 2.43-3.65). CONCLUSIONS: After adjusting for known covariates, residential zip code was associated with low-acuity EMS activation, stressing the importance of geographic variation in EMS use. Providing alternate means of transportation, or targeted education to certain residential areas, may decrease unnecessary EMS activation.

Pediatric emergency medicine asynchronous e-learning: a multicenter randomized controlled Solomon four-group study.

OBJECTIVES: Asynchronous e-learning allows for targeted teaching, particularly advantageous when bedside and didactic education is insufficient. An asynchronous e-learning curriculum has not been studied across multiple centers in the context of a clinical rotation. We hypothesize that an asynchronous e-learning curriculum during the pediatric emergency medicine (EM) rotation improves medical knowledge among residents and students across multiple participating centers. METHODS: Trainees on pediatric EM rotations at four large pediatric centers from 2012 to 2013 were randomized in a Solomon four-group design. The experimental arms received an asynchronous e-learning curriculum consisting of nine Web-based, interactive, peer-reviewed Flash/HTML5 modules. Postrotation testing and in-training examination (ITE) scores quantified improvements in knowledge. A 2 × 2 analysis of covariance (ANCOVA) tested interaction and main effects, and Pearson's correlation tested associations between module usage, scores, and ITE scores. RESULTS: A total of 256 of 458 participants completed all study elements; 104 had access to asynchronous e-learning modules, and 152 were controls who used the current education standards. No pretest sensitization was found (p = 0.75). Use of asynchronous e-learning modules was associated with an improvement in posttest scores (p < 0.001), from a mean score of 18.45 (95% confidence interval [CI] = 17.92 to 18.98) to 21.30 (95% CI = 20.69 to 21.91), a large effect (partial η(2) = 0.19). Posttest scores correlated with ITE scores (r(2) = 0.14, p < 0.001) among pediatric residents. CONCLUSIONS: Asynchronous e-learning is an effective educational tool to improve knowledge in a clinical rotation. Web-based asynchronous e-learning is a promising modality to standardize education among multiple institutions with common curricula, particularly in clinical rotations where scheduling difficulties, seasonality, and variable experiences limit in-hospital learning.

Primary care spatial density and nonurgent emergency department utilization: a new methodology for evaluating access to care.

OBJECTIVE: To determine the spatial and demographic characteristics of pediatric patients who make nonurgent visits (NUVs) to an urban pediatric emergency department (ED). We hypothesized that the rate of NUVs would be inversely associated with the spatial density of primary care providers (PCPs). METHODS: A retrospective, cross-sectional analysis was conducted for all visits to Washington, DC's principal pediatric ED between 2003 and 2006. NUVs were defined by a unique algorithm combining resource allocation, ambulatory-sensitive diagnoses, and billing data. Multivariate linear regression analysis was used to determine the association of PCP density and demographic variables on the spatial rate of NUVs. RESULTS: Over the 4-year period, 35.1% (52,110) of the 148,314 ED visits by Washington, DC, residents were nonurgent. NUVs were most associated with neighborhood median household income <$40,000 and low spatial density of PCPs. For every 1-unit increase in PCP density, the spatial rate of NUVs decreased by 9%. The odds of a visit being nonurgent were significantly higher for African Americans and Hispanics than for whites (odds ratio [OR] 2.4, 95% confidence interval [CI] 2.19-2.64; and OR 2.6, 95% CI 2.36-2.86, respectively), for patients using public insurance versus private (OR 1.46, 95% CI 1.42-1.50), and for patients age <5 years (OR 2.66, 95% CI 2.60-2.72). CONCLUSIONS: Low spatial density of primary care is strongly associated with nonurgent ED utilization. Improving spatial distribution of primary care may decrease ED misuse and improve access to the medical home.

Fever and limp: thinking outside the box.

Fever and limp is a common presentation in the pediatric emergency department. We describe a case of a 21-month-old female patient with prolonged fever and difficulty bearing weight, ultimately diagnosed with a large intracranial abscess. Intracranial abscesses are a rare cause of limp and an uncommon diagnosis in pediatric patients without underlying congenital heart disease. This case highlights the importance of differentiating the features of limp secondary to pain from limp secondary to weakness, which is particularly difficult in the preschool-aged group. It is imperative for practitioners to consider disease of the central nervous system when evaluating acutely nonambulatory children with fevers.

A rapid medical screening process improves emergency department patient flow during surge associated with novel H1N1 influenza virus.

STUDY OBJECTIVE: We compare emergency department (ED) patient flow during the fall 2009 novel H1N1-associated surge in patient volumes at an urban, tertiary care, pediatric medical center to that in the previous winter virus season. METHODS: A rapid medical screening process was instituted to manage the surge in patient census. The process included the use of a new, separate clinical area converted from office space adjacent to the ED, the introduction of a new preprinted checklist for rapid documentation of medical history and physical examination of patients with influenza-like illness, the use of classroom-style parent discharge education, and the use of preprinted discharge prescription and instructions. We compared patient flow parameters, including waiting time, length of stay, and elopement rates, and returns within 48 hours and 7 days for a comparable period in winter 2008 to 2009. RESULTS: During the first 30 days of the novel H1N1-associated surge in patient volumes (October 12 to November 10, 2009), overall ED daily volumes increased by a mean of 113 (51.8%) compared with baseline (daily increase range 49 to 118 patients). Of the 10,013 patients treated during this period, 4,287 (42.8%) had complaints consistent with influenza-like illness and 1,767 (17.6%) were treated with the rapid screening process. The mean wait time decreased from 92.9 to 81.2 minutes (difference 11.7 minutes; 95% confidence interval [CI] 10.2 to 13.2 minutes). Overall mean ED length of stay decreased from 241 to 212.3 minutes (difference 28.7 minutes; 95% CI 25.8 to 31.6 minutes). Rates of elopement were unchanged, and elopement rates as a function of daily patient volumes showed improved responsiveness to high volumes. Rates of return were unchanged within 48 hours (3.0% in 2009 versus 2.9% in 2008; odds ratio 1.03 [0.91 to 1.18]) and within 7 days (6.2% in 2009 versus 5.7% in 2008; odds ratio 1.09 [0.99 to 1.20]). The use of the rapid screening process required a mean of 23.5 (95% CI 16.4 to 30.6) additional hours per day of physician staffing and a mean of 26.3 (95% CI 18.5 to 34.1) additional hours of nursing staffing. CONCLUSION: The implementation of a rapid screening process during the fall 2009 H1N1-associated surge in patient volumes was associated with improved patient flow without affecting rates of return to the ED within 48 hours or 7 days. This was accomplished with only a modest increase in staffing.

An update on the epidemiology of pediatric fractures.

Despite public health measures to prevent childhood injuries, the incidence of pediatric fractures is increasing. This fracture incidence is dependent on many demographic factors, the various contributors to bone health, and an individual's risk-taking behavior. Although traditional play activities continue to be the prevalent causes for fractures, there is an evolving array of new sport and recreation activities that carry significant fracture risk. The following review article outlines the developing epidemiology of pediatric fractures by analyzing some of the individual risk factors that influence fracture incidence as well as the variety of activities that are associated with these fractures.

Approach to knee effusions.

The presence of an intra-articular knee effusion requires an extensive differential diagnosis and a systematic diagnostic approach. Pediatric knee effusions occur most commonly as acute hemarthroses after traumatic injury. However, the knee joint is susceptible to effusions secondary to a wide variety of atraumatic causes. Special attention is required in the atraumatic effusion to distinguish features of infectious, postinfectious, rheumatologic, hematologic, vasculitic, and malignant disease. This review discusses the various etiologies of both traumatic and atraumatic pediatric knee effusions highlighting the historical, physical examination, and laboratory characteristics to aid the emergency provider in diagnosis and initial management.

Toward early identification of acute lung injury in the emergency department.

BACKGROUND: There are no studies evaluating the epidemiology of pediatric acute lung injury (ALI) in the emergency department (ED), where early identification and interventions are most likely to be helpful. The purpose of this study was to describe the epidemiology of the ALI precursor acute hypoxemic respiratory failure (AHRF) in the ED. METHODS: We analyzed 11,664 pediatric patient records from 16 EDs. Records were selected if oxygen saturation (SpO(2)) was recorded during the visit. Virtual partial pressure of oxygen (pO(2)) was calculated from SpO(2), thus allowing calculation of ratios of pO(2) to fraction of inspired oxygen (FiO(2)) (PFRs). Patients with a PFR < 300 were classified as having AHRF. Univariate analyses and logistic regression were used to test the association of clinical factors with the presence of AHRF and intubation. RESULTS: AHRF criteria (ie, PFR < 300) were met in 121 (2.9%) of the 4,184 patients with an oxygenation measurement. The following variables were independently associated with ALI: higher Pediatric Risk of Admission II score (adjusted odds ratio [95% confidence interval (CI)] = 1.12 [1.08-1.16]; p < .001), higher heart rate (1.02 [1.01-1.03]; p = .009), a positive chest radiograph (2.35 [1.02-5.43]; p = .045), and lower temperature (0.49 [0.36-0.68]; p < .001).The final model had an R(2) = .20. CONCLUSION: We found nonintubated AHRF to be prevalent in the ED. The low R(2) for the regression model for AHRF underscores the lack of criteria for early identification of patients with respiratory compromise. Our findings represent an important first step toward establishing the true incidence of ALI in the pediatric ED.
