Predicting Adverse Outcomes for Shiga Toxin-Producing Escherichia coli Infections in Emergency Departments.

OBJECTIVE: To assess the performance of a hemolytic uremic syndrome (HUS) severity score among children with Shiga toxin-producing Escherichia coli (STEC) infections and HUS by stratifying them according to their risk of adverse events. The score has not been previously evaluated in a North American acute care setting. STUDY DESIGN: We reviewed medical records of children <18 years old infected with STEC and treated in 1 of 38 participating emergency departments in North America between 2011 and 2015. The HUS severity score (hemoglobin [g/dL] plus 2-times serum creatinine [mg/dL]) was calculated using first available laboratory results. Children with scores >13 were designated as high-risk. We assessed score performance to predict severe adverse events (ie, dialysis, neurologic complication, respiratory failure, and death) using discrimination and net benefit (ie, threshold probability), with subgroup analyses by age and day-of-illness. RESULTS: A total of 167 children had HUS, of whom 92.8% (155/167) had relevant data to calculate the score; 60.6% (94/155) experienced a severe adverse event. Discrimination was acceptable overall (area under the curve 0.71, 95% CI 0.63-0.79) and better among children <5 years old (area under the curve 0.77, 95% CI 0.68-0.87). For children <5 years, greatest net benefit was achieved for a threshold probability >26%. CONCLUSIONS: The HUS severity score was able to discriminate between high- and low-risk children <5 years old with STEC-associated HUS at a statistically acceptable level; however, it did not appear to provide clinical benefit at a meaningful risk threshold.

Predicting Hemolytic Uremic Syndrome and Renal Replacement Therapy in Shiga Toxin-producing Escherichia coli-infected Children.

BACKGROUND: Shiga toxin-producing Escherichia coli (STEC) infections are leading causes of pediatric acute renal failure. Identifying hemolytic uremic syndrome (HUS) risk factors is needed to guide care. METHODS: We conducted a multicenter, historical cohort study to identify features associated with development of HUS (primary outcome) and need for renal replacement therapy (RRT) (secondary outcome) in STEC-infected children without HUS at initial presentation. Children aged <18 years who submitted STEC-positive specimens between January 2011 and December 2015 at a participating study institution were eligible. RESULTS: Of 927 STEC-infected children, 41 (4.4%) had HUS at presentation; of the remaining 886, 126 (14.2%) developed HUS. Predictors (all shown as odds ratio [OR] with 95% confidence interval [CI]) of HUS included younger age (0.77 [.69-.85] per year), leukocyte count ≥13.0 × 103/µL (2.54 [1.42-4.54]), higher hematocrit (1.83 [1.21-2.77] per 5% increase) and serum creatinine (10.82 [1.49-78.69] per 1 mg/dL increase), platelet count <250 × 103/µL (1.92 [1.02-3.60]), lower serum sodium (1.12 [1.02-1.23 per 1 mmol/L decrease), and intravenous fluid administration initiated ≥4 days following diarrhea onset (2.50 [1.14-5.46]). A longer interval from diarrhea onset to index visit was associated with reduced HUS risk (OR, 0.70 [95% CI, .54-.90]). RRT predictors (all shown as OR [95% CI]) included female sex (2.27 [1.14-4.50]), younger age (0.83 [.74-.92] per year), lower serum sodium (1.15 [1.04-1.27] per mmol/L decrease), higher leukocyte count ≥13.0 × 103/µL (2.35 [1.17-4.72]) and creatinine (7.75 [1.20-50.16] per 1 mg/dL increase) concentrations, and initial intravenous fluid administration ≥4 days following diarrhea onset (2.71 [1.18-6.21]). CONCLUSIONS: The complex nature of STEC infection renders predicting its course a challenge. Risk factors we identified highlight the importance of avoiding dehydration and performing close clinical and laboratory monitoring.

Association Between Initial Emergency Department Lactate and Use of Vasoactive Medication in Children With Septic Shock.

OBJECTIVES: Current guidelines emphasize early recognition of pediatric septic shock using clinical examination findings. Elevated serum lactate has been associated with increased mortality in adult patients with septic shock. Our objective was to determine the association between the initial serum lactate obtained in the pediatric emergency department (PED) from patients treated for septic shock and the use of vasoactive medication within 24 hours. METHODS: This was a retrospective study from 2008 through 2012 of PED patients at a tertiary care children's hospital. Patients younger than 18 years treated for septic shock were included if they had a serum lactate obtained in the PED. RESULTS: Eight hundred sixty-four PED encounters met inclusion criteria. Median initial PED lactate was 2.1 mmol/L (interquartile range, 1.4-3.2 mmol/L). Overall, 121 patients (14%) received vasoactive medication within 24 hours of the initial PED lactate. A multivariable logistic regression analysis demonstrated associations between initial lactate levels of 3.1 to 5 mmol/L (odds ratio, 1.82; 95% confidence interval, 1.02-3.26) and 5.1 mmol/L or greater (odds ratio, 5.00; 95% confidence interval, 2.56-9.76) and the use of vasoactive medication within 24 hours. Other factors associated with use of vasoactive medication within 24 hours included hypotension, abnormal pulses, and mental status changes. CONCLUSIONS: Increased initial lactate is associated with use of vasoactive medication within 24 hours in PED patients with septic shock.

Pediatric emergency department triage-based pain guideline utilizing intranasal fentanyl: Effect of implementation.

BACKGROUND: Pain management guidelines in the emergency department (ED) may reduce time to analgesia administration (TTA). Intranasal fentanyl (INF) is a safe and effective alternative to intravenous opiates. The effect of an ED pain management guideline providing standing orders for nurse-initiated administration of intranasal fentanyl (INF) is not known. The objective of this study was to determine the impact of a pediatric ED triage-based pain protocol utilizing intranasal fentanyl (INF) on time to analgesia administration (TTA) and patient and parent satisfaction. METHODS: This was a prospective study of patients 3-17 years with an isolated orthopedic injury presenting to a pediatric ED before and after instituting a triage-based pain guideline allowing for administration of INF by triage nurses. Our primary outcome was median TTA and secondary outcomes included the proportion of patients who received INF for pain, had unnecessary IV placement, and patient and parent satisfaction. RESULTS: We enrolled 132 patients; 72 pre-guideline, 60 post-guideline. Demographics were similar between groups. Median TTA was not different between groups (34.5 min vs. 33 min, p = .7). Utilization of INF increased from 41% pre-guideline to 60% post-guideline (p = .01) and unnecessary IV placement decreased from 24% to 0% (p = .002). Patients and parents preferred the IN route for analgesia administration. CONCLUSION: A triage-based pain protocol utilizing INF did not reduce TTA, but did result in increased INF use, decreased unnecessary IV placement, and was preferred by patients and parents to IV medication. INF is a viable analgesia alternative for children with isolated extremity injuries.

Delays to Antibiotics in the Emergency Department and Risk of Mortality in Children With Sepsis.

Importance: Pediatric consensus guidelines recommend antibiotic administration within 1 hour for septic shock and within 3 hours for sepsis without shock. Limited studies exist identifying a specific time past which delays in antibiotic administration are associated with worse outcomes. Objective: To determine a time point for antibiotic administration that is associated with increased risk of mortality among pediatric patients with sepsis. Design, Setting, and Participants: This retrospective cohort study used data from 51 US children's hospitals in the Improving Pediatric Sepsis Outcomes collaborative. Participants included patients aged 29 days to less than 18 years with sepsis recognized within 1 hour of emergency department arrival, from January 1, 2017, through December 31, 2021. Piecewise regression was used to identify the inflection point for sepsis-attributable 3-day mortality, and logistic regression was used to evaluate odds of sepsis-attributable mortality after adjustment for potential confounders. Data analysis was performed from March 2022 to February 2024. Exposure: The number of minutes from emergency department arrival to antibiotic administration. Main Outcomes and Measures: The primary outcome was sepsis-attributable 3-day mortality. Sepsis-attributable 30-day mortality was a secondary outcome. Results: A total of 19 515 cases (median [IQR] age, 6 [2-12] years) were included. The median (IQR) time to antibiotic administration was 69 (47-116) minutes. The estimated time to antibiotic administration at which 3-day sepsis-attributable mortality increased was 330 minutes. Patients who received an antibiotic in less than 330 minutes (19 164 patients) had sepsis-attributable 3-day mortality of 0.5% (93 patients) and 30-day mortality of 0.9% (163 patients). Patients who received antibiotics at 330 minutes or later (351 patients) had 3-day sepsis-attributable mortality of 1.2% (4 patients), 30-day mortality of 2.0% (7 patients), and increased adjusted odds of mortality at both 3 days (odds ratio, 3.44; 95% CI, 1.20-9.93; P = .02) and 30 days (odds ratio, 3.63; 95% CI, 1.59-8.30; P = .002) compared with those who received antibiotics within 330 minutes. Conclusions and Relevance: In this cohort of pediatric patients with sepsis, 3-day and 30-day sepsis-attributable mortality increased with delays in antibiotic administration 330 minutes or longer from emergency department arrival. These findings are consistent with the literature demonstrating increased pediatric sepsis mortality associated with antibiotic administration delay. To guide the balance of appropriate resource allocation with time for adequate diagnostic evaluation, further research is needed into whether there are subpopulations, such as those with shock or bacteremia, that may benefit from earlier antibiotics.

Reducing Admission for Anaphylaxis in a Pediatric Emergency Department Using a Clinical Decision Support Tool.

Introduction: Anaphylaxis is a life-threatening condition necessitating emergent management. However, the benefits of prolonged observation and indications for hospitalization are not well established. Through the implementation of a disposition-focused clinical decision support tool (CDST), this quality improvement initiative aimed to reduce hospitalization for low-risk patients presenting to the pediatric emergency department (PED) with anaphylaxis from 49% to ≤12% within 12 months of implementation. Methods: The intervention included patients 18 years and younger of age presenting with anaphylaxis to the PED. A multidisciplinary team identified a 2006 evidence-based guideline as a significant contributor to hospitalization. The updated guideline incorporated a disposition-focused CDST that stratified patients as low-risk or high-risk and recommended discharge of low-risk patients after a 4-hour observation period. The primary outcome measure was the percentage of low-risk patients hospitalized. Balancing measures included low-risk patient 72-hour return rate and PED length of stay for all comers. Secondary outcomes included a focused cost analysis. Results: Fifty-three children preintervention and 43 children postintervention presenting with anaphylaxis met low-risk criteria. Postimplementation, hospitalization of low-risk patients decreased from 49% to 7% (P < 0.0001). No low-risk patients returned in 72 hours for an anaphylaxis-related concern (P = 0.83). The median PED length of stay increased from 189 to 193 minutes (P < 0.0001). The median cost per low-risk encounter decreased by $377 (P = 0.013). Conclusions: After implementing an evidence-based disposition-focused CDST, hospitalization of low-risk patients presenting to the PED with anaphylaxis significantly decreased without an increase in 72-hour returns. In addition, patient encounters demonstrated cost savings.

Medication and Fluid Management of Pediatric Sepsis and Septic Shock.

Sepsis is a life-threatening response to infection that contributes significantly to neonatal and pediatric morbidity and mortality worldwide. The key tenets of care include early recognition of potential sepsis, rapid intervention with appropriate fluids to restore adequate tissue perfusion, and empiric antibiotics to cover likely pathogens. Vasoactive/inotropic agents are recommended if tissue perfusion and hemodynamics are inadequate following initial fluid resuscitation. Several adjunctive therapies have been suggested with theoretical benefit, though definitive recommendations are not yet supported by research reports. This review focuses on the recommendations for medication and fluid management of pediatric sepsis and septic shock, highlighting issues related to antibiotic choices and antimicrobial stewardship, selection of intravenous fluids for resuscitation, and selection and use of vasoactive/inotropic medications. Controversy remains regarding resuscitation fluid volume and type, antibiotic choices depending upon infectious risks in the patient's community, and adjunctive therapies such as vitamin C, corticosteroids, intravenous immunoglobulin, and methylene blue. We include best practice recommendations based on international guidelines, a review of primary literature, and a discussion of ongoing clinical trials and the nuances of therapeutic choices.

Pediatric Septic Shock Collaborative Improves Emergency Department Sepsis Care in Children.

OBJECTIVES: The pediatric emergency department (ED)-based Pediatric Septic Shock Collaborative (PSSC) aimed to improve mortality and key care processes among children with presumed septic shock. METHODS: This was a multicenter learning and improvement collaborative of 19 pediatric EDs from November 2013 to May 2016 with shared screening and patient identification recommendations, bundles of care, and educational materials. Process metrics included minutes to initial vital sign assessment and to first and third fluid bolus and antibiotic administration. Outcomes included 3- and 30-day all-cause in-hospital mortality, hospital and ICU lengths of stay, hours on increased ventilation (including new and increases from chronic baseline in invasive and noninvasive ventilation), and hours on vasoactive agent support. Analysis used statistical process control charts and included both the overall sample and an ICU subgroup. RESULTS: Process improvements were noted in timely vital sign assessment and receipt of antibiotics in the overall group. Timely first bolus and antibiotics improved in the ICU subgroup. There was a decrease in 30-day all-cause in-hospital mortality in the overall sample. CONCLUSIONS: A multicenter pediatric ED improvement collaborative showed improvement in key processes for early sepsis management and demonstrated that a bundled quality improvement-focused approach to sepsis management can be effective in improving care.

Omphalitis and Concurrent Serious Bacterial Infection.

OBJECTIVE: Describe the clinical presentation, prevalence of concurrent serious bacterial infection (SBI), and outcomes among infants with omphalitis. METHODS: Within the Pediatric Emergency Medicine Collaborative Research Committee, 28 sites reviewed records of infants ≤90 days of age with omphalitis seen in the emergency department from January 1, 2008, to December 31, 2017. Demographic, clinical, laboratory, treatment, and outcome data were summarized. RESULTS: Among 566 infants (median age 16 days), 537 (95%) were well-appearing, 64 (11%) had fever at home or in the emergency department, and 143 (25%) had reported fussiness or poor feeding. Blood, urine, and cerebrospinal fluid cultures were collected in 472 (83%), 326 (58%), and 222 (39%) infants, respectively. Pathogens grew in 1.1% (95% confidence interval [CI], 0.3%-2.5%) of blood, 0.9% (95% CI, 0.2%-2.7%) of urine, and 0.9% (95% CI, 0.1%-3.2%) of cerebrospinal fluid cultures. Cultures from the site of infection were obtained in 320 (57%) infants, with 85% (95% CI, 80%-88%) growing a pathogen, most commonly methicillin-sensitive Staphylococcus aureus (62%), followed by methicillin-resistant Staphylococcus aureus (11%) and Escherichia coli (10%). Four hundred ninety-eight (88%) were hospitalized, 81 (16%) to an ICU. Twelve (2.1% [95% CI, 1.1%-3.7%]) had sepsis or shock, and 2 (0.4% [95% CI, 0.0%-1.3%]) had severe cellulitis or necrotizing soft tissue infection. There was 1 death. Serious complications occurred only in infants aged <28 days. CONCLUSIONS: In this multicenter cohort, mild, localized disease was typical of omphalitis. SBI and adverse outcomes were uncommon. Depending on age, routine testing for SBI is likely unnecessary in most afebrile, well-appearing infants with omphalitis.

Best practices in pediatric sepsis: building and sustaining an evidence-based pediatric sepsis quality improvement program.

Pediatric sepsis is a common problem worldwide and is associated with significant morbidity and mortality. Best practice recommendations have been published by both the American College of Critical Care Medicine and the Surviving Sepsis Campaign to guide the recognition and treatment of pediatric sepsis. However, implementation of these recommendations can be challenging due to the complexity of the care required and intensity of resources needed to successfully implement programs. This paper outlines the experience with implementation of a pediatric sepsis quality improvement program at Primary Children's Hospital, a free-standing, quaternary care children's hospital in Salt Lake City. The hospital has implemented sepsis projects across multiple care settings. Challenges, lessons learned, and suggestions for implementation are described.PLAIN LANGUAGE SUMMARYSepsis is a life-threatening condition that results from an inappropriate response to an infection by the body's immune system. All children are potentially susceptible to sepsis, with nearly 8,000 children dying from the disease in the US each year. Sepsis is a complicated disease, and several international groups have published guidelines to help hospital teams treat children with sepsis appropriately. However, because recognizing and treating sepsis in children is challenging and takes a coordinated effort from many different types of healthcare team members, following the international sepsis guidelines effectively can be difficult and resource intensive. This paper describes how one children's hospital (Primary Children's Hospital in Salt Lake City, Utah) approached the challenge of implementing pediatric sepsis guidelines, some lessons learned from their experience, and suggestions for others interested in implementing sepsis guidelines for children.

Neonatal Mastitis and Concurrent Serious Bacterial Infection.

OBJECTIVES: Describe the clinical presentation, prevalence, and outcomes of concurrent serious bacterial infection (SBI) among infants with mastitis. METHODS: Within the Pediatric Emergency Medicine Collaborative Research Committee, 28 sites reviewed records of infants aged ≤90 days with mastitis who were seen in the emergency department between January 1, 2008, and December 31, 2017. Demographic, clinical, laboratory, treatment, and outcome data were summarized. RESULTS: Among 657 infants (median age 21 days), 641 (98%) were well appearing, 138 (21%) had history of fever at home or in the emergency department, and 63 (10%) had reported fussiness or poor feeding. Blood, urine, and cerebrospinal fluid cultures were collected in 581 (88%), 274 (42%), and 216 (33%) infants, respectively. Pathogens grew in 0.3% (95% confidence interval [CI] 0.04-1.2) of blood, 1.1% (95% CI 0.2-3.2) of urine, and 0.4% (95% CI 0.01-2.5) of cerebrospinal fluid cultures. Cultures from the site of infection were obtained in 335 (51%) infants, with 77% (95% CI 72-81) growing a pathogen, most commonly methicillin-resistant Staphylococcus aureus (54%), followed by methicillin-susceptible S aureus (29%), and unspecified S aureus (8%). A total of 591 (90%) infants were admitted to the hospital, with 22 (3.7%) admitted to an ICU. Overall, 10 (1.5% [95% CI 0.7-2.8]) had sepsis or shock, and 2 (0.3% [95% CI 0.04-1.1]) had severe cellulitis or necrotizing soft tissue infection. None received vasopressors or endotracheal intubation. There were no deaths. CONCLUSIONS: In this multicenter cohort, mild localized disease was typical of neonatal mastitis. SBI and adverse outcomes were rare. Evaluation for SBI is likely unnecessary in most afebrile, well-appearing infants with mastitis.

Sunflower rectal bezoar presenting with an acute abdomen in a 3-year-old child.

This is a case of a 3-year-old boy with a sunflower-seed rectal bezoar who presented to our emergency department with fever, abdominal pain, leukocytosis, vomiting, and an examination concerning for appendicitis. A failed diagnostic imaging attempt ultimately led to the diagnosis. Children with rectal bezoars typically present with diarrhea, rectal pain, and tenesmus. Our patient presented atypically and developed significant colitis secondary to the bezoar. We discuss bezoars and the uncommon rectal seed bezoar. This case illustrates an atypical complication (colitis) of an unusual condition (rectal bezoar) mimicking a relatively common illness (appendicitis).

Amiodarone for the emergency care of children.

Amiodarone is a class 3 antiarrhythmic agent used for a broad range of arrhythmias including adenosine-resistant supraventricular tachycardia, junctional ectopic tachycardia, and ventricular tachycardia. Compared with adults, there are few data on its use in children with arrhythmias resistant to conventional therapy. National and international guidelines for cardiopulmonary resuscitation and emergency cardiovascular care recommend its use for a variety of arrhythmias based on case reports, cohort studies, and extrapolation from adult data. This article will review the historical development, chemical properties, metabolism, indications and contraindications, and adverse effects of amiodarone in infants and children. After completing this CME activity, the reader should be able to utilize amiodarone in the pediatric population for arrhythmias and identify complications associated with its use.

Antibiotic Timing in Pediatric Septic Shock.

BACKGROUND AND OBJECTIVES: National guidelines advocate for the administration of antibiotics within 1 hour to children with septic shock, although there is variance in the pediatric evidence-based literature supporting this benchmark. Our objective for this study was to describe the association of target time to antibiotic administration (TTAA) with outcomes of children treated for suspected septic shock in a pediatric emergency department. Septic shock is suspected when signs of perfusion and/or hypotension are present. The primary outcome was mortality. Secondary outcomes included PICU admission, hospital and PICU length of stay, and organ dysfunction resolution by hospital day 2. METHODS: We conducted a retrospective study of children <18 years of age admitted from the pediatric emergency department and treated for suspected septic shock between February 1, 2007, and December 31, 2015. Associations between TTAA and outcomes were evaluated by using multivariable linear and logistic regression models obtained from stepwise selection. RESULTS: Of 1377 patients, 47% were boys with a median age of 4.0 (interquartile range 1.4-11.6) years, 1.5% (20) died, 90% were compliant with TTAA goals, 40% required PICU admission, 38% had ≥2 unique complex chronic conditions, 71% received antibiotics in ≤2 hours, and 30% had a culture-positive bacterial etiology. There were no significant associations between TTAA and outcomes. CONCLUSIONS: We found no association with TTAA and any clinical outcomes, adding to the growing body of literature questioning the timing benchmark of antibiotic administration. Although the importance of antibiotics is not in question, elucidating the target TTAA may improve resource use and decrease inappropriate or unnecessary antibiotic exposure.

Updates on pediatric sepsis.

Sepsis, defined as an infection with dysregulated host response leading to life-threatening organ dysfunction, continues to carry a high potential for morbidity and mortality in children. The recognition of sepsis in children in the emergency department (ED) can be challenging, related to the high prevalence of common febrile infections, poor specificity of discriminating features, and the capacity of children to compensate until advanced stages of shock. Sepsis outcomes are strongly dependent on the timeliness of recognition and treatment, which has led to the successful implementation of quality improvement programs, increasing the reliability of sepsis treatment in many US institutions. We review clinical, laboratory, and technical modalities that can be incorporated into ED practice to facilitate the recognition, treatment, and reassessment of children with suspected sepsis. The 2020 updated pediatric sepsis guidelines are reviewed and framed in the context of ED interventions, including guidelines for antibiotic administration, fluid resuscitation, and the use of vasoactive agents. Despite a large body of literature on pediatric sepsis epidemiology in recent years, the evidence base for treatment and management components remains limited, implying an urgent need for large trials in this field. In conclusion, although the burden and impact of pediatric sepsis remains substantial, progress in our understanding of the disease and its management have led to revised guidelines and the available data emphasizes the importance of local quality improvement programs.

Atomized intranasal midazolam use for minor procedures in the pediatric emergency department.

BACKGROUND: Procedural sedation is increasingly more common in pediatric emergency departments. We report our experience with intranasal midazolam (INM) using a unique atomization delivery device, specifically the efficacy and safety of this method of sedation. METHODS: We performed a retrospective chart review of children who received INM sedation in the emergency department from April 1, 2005, through June 30, 2005. All children aged 1 to 60 months who received INM as the initial means of sedation were eligible for the study. Patients were excluded if they were older than 60 months. RESULTS: There were 205 patients who received INM for sedation and who met the study criteria. The mean age was 31.3 +/- 13.2 months (range, 1.5-60 months). The mean and median initial INM dose was 0.4 mg/kg (range, 0.3-0.8 mg/kg). Laceration repair was the most common procedure necessitating sedation (89%). The median degree-of-sedation score achieved was 2.0 (anxiolysis). Eleven patients (5.4%; 95% CI, 3%-9%) required an additional sedative to complete the procedure. Ten of the 11 patients received ketamine as the adjunctive sedative, and 1 patient required additional INM. The average time of last oral intake to start of sedation was 3.5 hours (range, 0.5-10.0 hours). Thirty six patients (18%) were NPO for 2 hours or less. There was 1 adverse event (0.5%; 95% CI, 0%-3%). This was a minor desaturation episode following ketamine administration requiring brief blow by oxygen. There were no adverse events (0%; 95% CI, 0%-2%) in patients who received INM alone. CONCLUSION: We conclude that atomized INM is effective in providing anxiolysis to children undergoing minor procedures in the pediatric emergency department. We are encouraged that no adverse events occurred with the use of INM alone despite relatively short fasting times.

High Reliability Pediatric Septic Shock Quality Improvement Initiative and Decreasing Mortality.

BACKGROUND AND OBJECTIVE: Septic shock impacts mortality, morbidity, and health care costs. A quality improvement (QI) initiative was launched to improve early recognition and timely treatment of patients with septic shock in a pediatric emergency department (PED). Our primary aim was to describe the longitudinal effectiveness of the program, iterative changes in clinical practice, and associated outcomes. METHODS: We implemented multiple interventions during our QI initiative (February 2007 to December 2014). Analysis of compliance and outcomes focused on a bundle consisting of: (1) timely antibiotics, (2) intravenous fluids (IVF) for rapid reversal of perfusion abnormalities and/or hypotension. Logistic regression was used to obtain adjusted odds ratios (ORs) for death and pediatric ICU (PICU) admission. RESULTS: A total of 1380 patients were treated for septic shock; 93% met screening criteria at triage. Implementation of the various processes improved timely interventions. One example included implementation of a sepsis order set, after which the mean proportion of patients receiving timely antibiotics increased to its highest rate. The odds of death were 5 times as high for children who did not receive bundle-compliant care (OR, 5.0 [95% Confidence Interval 1.9, 14.3]) compared with those who did (OR, 0.20 [95% Confidence Interval 0.07, 0.53]). Among PICU admitted patients, the odds of mortality were greater for children who presented with abnormal mental status and a higher pediatric index of mortality 2 score. CONCLUSIONS: QI methodology improved septic shock program goal adherence and decreased mortality without increasing PICU admissions or PED length of stay over the 8-year period, supporting continued emphasis on early recognition, timely IVF resuscitation, and antibiotic administration.

Treatment of skin and soft tissue infections in a pediatric observation unit.

OBJECTIVES: To report the success rate of observation unit (OU) treatment of pediatric skin and soft tissue infections (SSTIs) and to see if we could identify variables at the time of initial evaluation that predicted successful OU treatment. METHODS: A retrospective review of children less than 18 years of age admitted for SSTI treatment to our OU from the emergency department between January 2003 and June 2009. RESULTS: On records review, 853 patients matched eligibility criteria; median age was 5.2 years (interquartile range = 2.5-9 years). Of the 853 patients, 597 (70.0%) met the primary outcome criteria of successful OU discharge within 26 hours. Secondary analysis revealed that 82% of the patients achieved successful discharge from the OU within 48 hours. Although some laboratory variables demonstrated statistical association with success, none achieved a combination of high sensitivity and specificity to predict OU failure. OU success rates varied by location. Dental and face infections and those of the extremities or multiple sites demonstrated OU success rates higher than 65%, while infection of the groin, buttocks, trunk, or neck had success rates between 24% (neck) and 60% (groin). In multivariate analysis, only 3 variables remained significant. Unfavorable location was most strongly associated with OU failure, followed by C-reactive protein > 4 and then by erythrocyte sedimentation rate > 20. CONCLUSIONS: Our findings suggest that successful OU treatment is possible in a large group of patients needing hospitalization for SSTIs. Consideration of infection location may assist the emergency department clinician in determining the most appropriate unit for admission.
