Incidence of supraventricular tachycardia after inhaled short-acting beta agonist treatment in children.

INTRODUCTION: Albuterol can trigger supraventricular tachycardia (SVT). The clinical characteristics, incidence, and risk factors of SVT after inhaled SABA treatment in children are currently unknown. Through review of regional care delivery, we will describe cases of SVT during asthma treatment in hospital-based settings, define the incidence of SVT in our population, and evaluate risk factors of SABA-induced SVT. METHODS: We identified hospital-based care episodes of children 0-18 years old between 2006 and 2015 recorded in the Intermountain Healthcare EDW with either 1) diagnosis codes for both asthma and SVT or 2) both SABA and adenosine listed as billed medications. Controls were matched with cases by age and sex to determine risk factors for SVT after SABA using conditional logistic regression. RESULTS: Of 93 care episodes meeting criteria, we found 7 cases of SVT after SABA treatment in 6 patients over 10 years. In our population, the incidence of SVT is 3.9 per 10,000 episodes of SABA treatment, and 5.1 per 10,000 children with asthma receiving hospital-based asthma care. Two episodes of SVT followed treatment with only levalbuterol, three after only albuterol, and two after both albuterol and levalbuterol treatment. Five cases of SVT were converted to sinus rhythm with adenosine, one converted with synchronized electrical cardioversion, and one resolved spontaneously. No cases of SVT led to death. No examined variables were associated with SABA-induced SVT. CONCLUSIONS: SVT is rare during hospital-based treatment for acute asthma using inhaled SABAs and has low morbidity and mortality.

Unintentional Pediatric Poisoning Exposures in an Emergency Department: A Comparison of Poison Control Center Referrals and Caregiver Self-Referred Visits.

OBJECTIVES: The purpose of this study is to describe the demographics and clinical characteristics of patients referred to a pediatric emergency department (ED) for unintentional poisoning exposures by a poison control center (PCC) compared with patients/caregivers who self-refer. METHODS: The electronic data warehouse at a pediatric hospital was queried from October 1, 2014, to September 30, 2015, for unintentional poisoning-related ED visits and subsequent inpatient admissions. Eligible patients aged 18 years and younger were identified by International Classification of Diseases, Ninth Revision, Clinical Modification codes for pharmaceuticals, non-pharmaceuticalchemicals, fumes/vapors, foreign bodies, adverse food reactions, food poisoning, and bites/stings. Referral classification (PCC referral vs self-refer) was determined by PCC and hospital medical records.Descriptive statistics were used to characterize the patient demographics and ED visits by referral classification and age group. Simple and multiple logistic regression models examined the individual and combined impact of demographic and clinical characteristics on self-referral. RESULTS: Of the 705 patients identified, 84.4% presented as caregiver/self-referred compared with PCC-referred. As compared with those who self-referred, a higher percentage of patients who contacted the PCC before ED presentation were white (93.9% [89.4-98.2%] vs 83.8% [80.7-86.7%]) and had commercial insurance (62.7% [51.5-69.5%] vs 53.0% [48.9-57.0%]). Pharmaceutical (71.9%) and chemical (14.0%) exposures were the most common exposure types for PCC-referred patients whereas foreign bodies (54.3%) were the most common for self-referred patients. The largest predictors of self-referral were age, insurance, and exposure type. CONCLUSIONS: Among patients presenting at 1 pediatric ED, disparities with PCC utilization exist among age groups, racial identification, and poison exposure type. Educational outreach interventions are needed to ensure optimal use of the PCC services by patients, caregivers, and health care professionals.

Clinical pharmacokinetics of magnesium sulfate in the treatment of children with severe acute asthma.

PURPOSE: Intravenous (IV) magnesium sulfate (MgSO4) is used as adjunct therapy to treat acute asthma exacerbations. Despite its clinical use, there is a limited understanding of the disposition of magnesium in children. METHODS: To explore the pharmacokinetics (PK) of IV MgSO4 in this population, we collected retrospective data from 54 children who received IV MgSO4 for treatment of an acute asthma exacerbation at Primary Children's Hospital in Salt Lake City, UT. These data were analyzed using population PK modeling techniques in NONMEM® to determine sources of variability affecting the disposition of magnesium, as well as to predict the dose of IV MgSO4 needed to achieve clinical benefit. RESULTS: The covariate analysis found that only weight was a significant predictor of magnesium concentrations in children. Estimated model parameters suggested that magnesium exhibits a short serum half-life (2.7 h) in children. The average endogenous magnesium concentration (prior to administration of IV MgSO4) was estimated to be 21 mg/L. Simulated data suggested that doses between 50 and 75 mg/kg are required to achieve concentration-time profiles within a hypothesized target therapeutic range between 25 and 40 mg/L. CONCLUSIONS: These results provide new insight into the disposition of IV MgSO4 in children and provide dosing guidelines for future prospective studies of IV MgSO4 in children with acute asthma.

Variation in Computed Tomography Use for Evaluation of Head Injury in a Pediatric Emergency Department.

OBJECTIVES: Recent research has shown significant variation in rates of computed tomography (CT) use among pediatric hospital emergency departments (ED) for evaluation of head injured children. We examined the rates of CT use by individual ED attending physicians for evaluation of head injured children in a pediatric hospital ED. METHODS: We used an administrative database to identify children younger than 18 years evaluated for head injury from January 2011 through March 2013 at our children's hospital ED, staffed by pediatric emergency medicine (PEM) fellowship trained physicians and pediatricians. We excluded encounters with trauma team activation or previous head CT performed elsewhere. We excluded physicians whose patient volume was less than 1 standard deviation below the group mean. RESULTS: After exclusions, we evaluated 5340 encounters for head injury by 27 ED attending physicians. For individual physicians, CT rates ranged from 12.4% to 37.3%, with a mean group rate of 28.4%. Individual PEM physician CT rates ranged from 18.9% to 37.3%, versus 12.4% to 31.8% for pediatricians. Of the 1518 encounters in which CT was done, 128 (8.4%) had a traumatic brain injury on CT, and 125 (8.2%) had a simple skull fracture without traumatic brain injury on CT. Patient factors associated with CT use included age younger than 2 years, higher triage acuity, arrival time of 10:00 PM to 6:00 AM, hospital admission, and evaluation by a PEM physician. CONCLUSIONS: Physicians at our pediatric hospital ED varied in the use of CT for the evaluation of head-injured children.

Implementing an ultrasound-based protocol for diagnosing appendicitis while maintaining diagnostic accuracy.

BACKGROUND: The use of ultrasound to diagnose appendicitis in children is well-documented but not universally employed outside of pediatric academic centers, especially in the United States. Various obstacles make it difficult for institutions and radiologists to abandon a successful and accurate CT-based imaging protocol in favor of a US-based protocol. OBJECTIVE: To describe how we overcame barriers to implementing a US-based appendicitis protocol among a large group of nonacademic private-practice pediatric radiologists while maintaining diagnostic accuracy and decreasing medical costs. MATERIALS AND METHODS: A multidisciplinary team of physicians (pediatric surgery, pediatric emergency medicine and pediatric radiology) approved an imaging protocol using US as the primary modality to evaluate suspected appendicitis with CT for equivocal cases. The protocol addressed potential bias against US and accommodated for institutional limitations of radiologist and sonographer experience and availability. Radiologists coded US reports according to the probability of appendicitis. Radiology reports were compared with clinical outcomes to assess diagnostic accuracy. During the study period, physicians from each group were apprised of the interim US protocol accuracy results. Problematic cases were discussed openly. RESULTS: A total of 512 children were enrolled and underwent US for evaluation of appendicitis over a 30-month period. Diagnostic accuracy was comparable to published results for combined US/CT protocols. Comparing the first 12 months to the last 12 months of the study period, the proportion of children achieving an unequivocal US result increased from 30% (51/169) to 53% (149/282) and the proportion of children undergoing surgery based solely on US findings increased from 55% (23/42) to 84% (92/109). Overall, 63% (325/512) of patients in the protocol did not require a CT. Total patient costs were reduced by $30,182 annually. CONCLUSION: We overcame several barriers to implementing a US protocol. During the study period our ability to visualize the appendix with US increased and utilization of CT decreased. Our overall diagnostic accuracy with the US-based protocol was comparable to other published results and remained unchanged throughout the study.

Effect of gastrojejunal feedings on visits and costs in children with neurologic impairment.

OBJECTIVE: The objective of the present study was to determine the effect of gastrojejunal tube (GJT) feedings in children with neurologic impairment (NI) on gastroesophageal reflux disease (GERD)- and/or dysfunctional swallowing-related visits and their associated costs. METHODS: The present study is a retrospective cohort study of children with NI and GERD who underwent GJT placement at the study hospital from December 1999 to October 2006. Visits (emergency department, radiology, and hospitalizations) were reviewed from the time of birth until 1 year following GJT placement and classified as either not GERD and/or dysfunctional swallowing related or GERD and/or dysfunctional swallowing related (eg, pneumonias). Incident rate ratios (IRRs) were calculated by dividing the post-GJT visit rate by the pre-GJT visit rate. Other outcomes included associated costs, fundoplications, and deaths. RESULTS: Thirty-three patients met inclusion criteria. The IRR for total visits was 1.78 (95% confidence interval [CI] 1.12-2.81) and for GERD- and/or dysfunctional swallowing-related visits 2.88 (95% CI 1.68-4.94). Feeding tube-related visits (IRR 5.36, 95% CI 2.73-10.51) accounted for the majority. GERD- and/or dysfunctional swallowing-related costs per child per year were low overall, with no difference from pre-GJT versus post-GJT placement ($1851 vs $4601, P = 0.89). Seven (21%) children underwent Nissen fundoplication and 4 (12%) died within 1 year of GJT placement. Two deaths involved jejunal perforation. CONCLUSIONS: Children with NI and GERD who are treated with GJT feedings have significantly more GERD- and/or dysfunctional swallowing-related visits in the following year. The majority of these visits are because of the procedural complications, which are inexpensive. There is, however, mortality associated with the GJT and some children proceed to a fundoplication.

Determinants of health care use in a population-based leukodystrophy cohort.

OBJECTIVES: To determine the costs for children with leukodystrophies and whether high costs are associated with characteristic clinical features or resources use. STUDY DESIGN: We determined health care costs in a population cohort of 122 patients with leukodystrophies, including inpatient, outpatient, and emergency department use, during a 9-year period. We analyzed differences in patients with high costs (>85th percentile) and their health care use. RESULTS: Patients with leukodystrophy had significant variability in resource use, with the top 15th percentile of patients accounting for 73% of costs ($9.6 million). The majority of costs, 81% ($10.8 million), arose from inpatient hospitalization. High-cost patients had more and longer hospitalizations, increased requirements for intensive unit care and mechanical ventilation, and significantly more infections. Importantly, bone marrow transplantation did not solely account for the difference between high-cost and low-cost groups. CONCLUSION: Inpatient hospitalization is the greatest source of health care resource use in patients with leukodystrophies. A minority of patients account for the majority of costs, primarily attributable to an increased volume of hospitalization. Strategies to improve care and reduce costs will need to reduce inpatient stays and target modifiable reasons for hospitalization.

Macrophage activation syndrome in children with systemic lupus erythematosus and children with juvenile idiopathic arthritis.

OBJECTIVE: To describe patient demographics, interventions, and outcomes in hospitalized children with macrophage activation syndrome (MAS) complicating systemic lupus erythematosus (SLE) or juvenile idiopathic arthritis (JIA). METHODS: We performed a retrospective cohort study using data recorded in the Pediatric Health Information System (PHIS) database from October 1, 2006 to September 30, 2010. Participants had International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes for MAS and either SLE or JIA. The primary outcome was hospital mortality (for the index admission). Secondary outcomes included intensive care unit (ICU) admission, critical care interventions, and medication use. RESULTS: A total of 121 children at 28 children's hospitals met the inclusion criteria, including 19 children with SLE and 102 children with JIA. The index admission mortality rate was 7% (8 of 121 patients). ICU admission (33%), mechanical ventilation (26%), and inotrope/vasopressor therapy (26%) were common. Compared to children with JIA, those with SLE had a similar mortality rate (6% versus 11%, respectively; exact P = 0.6). More patients with SLE than those with JIA received ICU care (63% versus 27%; P = 0.002), received mechanical ventilation (53% versus 21%; P = 0.003), and had cardiovascular dysfunction (47% versus 23% received inotrope/vasopressor therapy; P = 0.02). Children with SLE and those with JIA received cyclosporine at similar rates, but more children with SLE received cyclophosphamide and mycophenolate mofetil, and more children with JIA received interleukin-1 antagonists. CONCLUSION: Organ system dysfunction is common in children with rheumatic diseases complicated by MAS, and more organ system support is required in children with underlying SLE than in children with JIA. Current treatment of pediatric MAS varies based on the underlying rheumatic disease.

Spinal muscular atrophy type 1: are proactive respiratory interventions associated with longer survival?

CONTEXT: Spinal muscular atrophy type 1, an autosomal recessive motor neuron disease, is a leading genetic cause of death in infancy and early childhood. OBJECTIVE: To determine whether the early initiation of noninvasive respiratory interventions is associated with longer survival. DESIGN: Single-institution retrospective cohort study identified children with spinal muscular atrophy type 1 from January 1, 2002 to May 1, 2009 who were followed for 2.3 mean yrs. SETTING: Tertiary care children's hospital and outpatient clinics in a vertically integrated healthcare system. PATIENTS OR OTHER PARTICIPANTS: Forty-nine children with spinal muscular atrophy type 1 were grouped according to the level of respiratory support their caregivers chose within the first 3 months after diagnosis: proactive respiratory care (n = 26) and supportive care (n = 23). INTERVENTIONS: Proactive respiratory care included bilevel noninvasive ventilation during sleep and twice a day cough assist while supportive respiratory care included suctioning, with or without supplemental oxygen. MEASUREMENTS AND MAIN RESULTS: Kaplan-Meier survival curves were assessed based on intention to treat. Children treated with early proactive respiratory support had statistically longer survival compared to supportive care (log rank 0.047); however, the adjusted hazard ratio for survival was not statistically different (2.44 [95% confidence interval 0.84-7.1]). Children in the proactive group were more likely to be hospitalized for respiratory insufficiency (83% vs. 46%) and had shortened time after diagnosis until first hospital admission for respiratory insufficiency (median 118 vs. 979 days). CONCLUSION: Longer survival time with spinal muscular atrophy type 1 is associated with early, noninvasive respiratory care interventions after diagnosis.

Inpatient capacity at children's hospitals during pandemic (H1N1) 2009 outbreak, United States.

Quantifying how close hospitals came to exhausting capacity during the outbreak of pandemic influenza A (H1N1) 2009 can help the health care system plan for more virulent pandemics. This ecologic analysis used emergency department (ED) and inpatient data from 34 US children's hospitals. For the 11-week pandemic (H1N1) 2009 period during fall 2009, inpatient occupancy reached 95%, which was lower than the 101% occupancy during the 2008-09 seasonal influenza period. Fewer than 1 additional admission per 10 inpatient beds would have caused hospitals to reach 100% occupancy. Using parameters based on historical precedent, we built 5 models projecting inpatient occupancy, varying the ED visit numbers and admission rate for influenza-related ED visits. The 5 scenarios projected median occupancy as high as 132% of capacity. The pandemic did not exhaust inpatient bed capacity, but a more virulent pandemic has the potential to push children's hospitals past their maximum inpatient capacity.

Implementing a Standardized Constipation-Management Pathway to Reduce Resource Utilization.

OBJECTIVE: Constipation is commonly diagnosed in our pediatric emergency department (ED). Care has varied significantly, with a heavy reliance on abdominal radiography (AR) for the diagnosis of and inpatient management for bowel cleanout. We implemented a standardized approach to caring for patients presenting to a pediatric ED with symptoms consistent with constipation, emphasizing clinical history, physical examination, less reliance on AR, and standardized home management. METHODS: Using quality improvement (QI) methodology, a multidisciplinary group developed an ED constipation management pathway, encouraging less reliance on AR for diagnosis and promoting home management over inpatient bowel cleanout. The pathway included a home management "gift basket" containing over-the-counter medications and educational materials to promote successful bowel cleanout. Outcome measures included pathway utilization, AR rate, ED cost and length of stay, and ED admission rate for constipation. RESULTS: Within 3 months, >90% of patients discharged home with an ED disposition diagnosis of constipation left with standardized educational materials and home medications. Staff education and feedback, pathway and gift basket changes, and a higher threshold for inpatient management led to significant decreases in AR rate (73.3%-24.6%, P < .001), average per-patient cost ($637.42-$538.85), length of stay (223-196 minutes, P < .001), and ED admission rate (15.3%-5.4%, P < .001), with no concerning missed diagnoses or increases in ED revisit rate. CONCLUSIONS: An ED QI project standardizing the care of pediatric constipation was implemented successfully, leading to a sustainable decrease in resource utilization. The next phase of the project will focus on collaborating with community providers to reduce ED utilization.

Outcomes After Skin and Soft Tissue Infection in Infants 90 Days Old or Younger.

BACKGROUND AND OBJECTIVES: Skin and soft tissue infections (SSTIs) are an increasingly common cause of pediatric hospital visits among infants. The optimal evaluation strategy for younger infants with SSTI is unknown because there is little information about outcomes including risks of concomitant bacterial infections and treatment failure. This study was designed to determine rates of concomitant invasive bacterial infection and hospital revisits for treatment failure as well as factors associated with treatment failure in infants presenting with SSTI. METHODS: Retrospective study of patients≤90 days of age who received care from the 22 emergency departments and hospitals in the Intermountain Healthcare system from July 1, 2004 to December 31, 2011, with a primary discharge diagnosis of SSTI. Concomitant bacterial infections were defined as urinary tract infection (UTI; culture-confirmed) or invasive bacterial infection (IBI; culture-confirmed bacteremia and/or meningitis). Treatment failure was defined as any unplanned change in care at hospital revisit within 14 days of discharge. RESULTS: The study included 172 infants; 29 (17%) were febrile, and 91 (53%) had ≥1 sterile site culture performed. One case of bacteremia in a febrile infant was identified giving an overall proportion with UTI/IBI of 0.58% (95% confidence interval 0.01%-3.2%). Sixteen infants (9.3%; 95% confidence interval 5.4%-14.7%) returned for treatment failure. Perianal location (P=.03) and private insurance status (P=.01) were associated with more treatment failures compared with other locations or payer types. No patients returned for missed UTI/IBI. CONCLUSIONS: Concomitant bacterial infections were rare in infants with SSTI, with none identified in afebrile infants. Treatment failure of SSTI leading to hospital revisit was common.

The effect of a computerized reminder system on the prevention of postoperative venous thromboembolism.

STUDY OBJECTIVE: To measure the effect of an altered process of care, directed by a computerized reminder system, on rates of symptomatic postoperative venous thromboembolism. DESIGN: Comparisons of preintervention and postintervention measurements. SETTING: A university-affiliated community hospital in Utah. PATIENTS: Two-thousand seventy-seven consecutive patients who underwent major operations in four surgical divisions between January 1, 1997, and October 31, 1997 (preintervention), and 2,093 consecutive patients who underwent the same procedures between January 1, 1998, and October 31,1998 (postintervention). INTERVENTION: A program to prevent venous thromboembolism developed from American College of Chest Physicians guidelines, and an altered work process directed by a computerized reminder system. MEASUREMENTS: Rates of symptomatic, objectively confirmed deep vein thrombosis (DVT), pulmonary embolism (PE), and death attributable to venous thromboembolism occurring within 90 days of the date of surgery. RESULTS: The preintervention and postintervention cohorts did not differ with respect to age, severity of illness, number of risk factors for venous thromboembolism, or individual risk factors for venous thromboembolism. The overall prophylaxis rate increased from 89.9% before implementation of the computerized reminder system to 95.0% after implementation (p < 0.0001). The combined 90-day rate of symptomatic DVT, PE, and death attributable to PE remained the same (preintervention, 1.0%; postintervention, 1.2%; odds ratio, 1.21; 95% confidence interval, 0.67 to 2.20). Forty of 46 venous thromboembolic complications (87%) occurred despite the delivery of American College of Chest Physicians-recommended measures to prevent venous thromboembolism. CONCLUSIONS: Computerized reminder systems combined with altered care procedures increase the rate of prophylaxis against venous thromboembolism without decreasing the rate of symptomatic venous thromboembolism when the baseline rate of prophylaxis is high. A population of surgical patients exists who are resistant to American College of Chest Physicians-recommended prophylactic measures against venous thromboembolism. New strategies are needed to address prophylaxis-resistant venous thromboembolism.

The medical and economic impact of the Newborns' and Mothers' Health Protection Act.

OBJECTIVE: We evaluated the effect of the Newborns' and Mothers' Health Protection Act on clinical and cost outcomes. METHODS: We conducted an observational study of 18,023 healthy, mother-infant dyads before (n = 8670) and after (n = 9353) implementation of the Newborns' and Mothers' Health Protection Act legislation. Logistic regression was used to calculate adjusted odds ratios (ORs) for the following outcome measures: length of stay at least 48 hours, satisfaction with maternal length of stay, 7- and 30-day hospital readmission utilization, and 7- and 30-day emergency room utilization. Analysis of covariance was used to evaluate adjusted mean hospitalization costs per delivery. RESULTS: Mothers in the postlegislation period were more likely to have hospital stays at least 48 hours (OR 3.99; 95% confidence interval [CI] 3.57, 4.44) and rate their length of stay as "about right" (OR 5.54; 95% CI 4.76, 6.46) compared with mothers in the prelegislation period. Neonates in the postlegislation period were more likely to have hospital stays of at least 48 hours (OR 3.96; 95% CI 3.54, 4.43) and less likely to be rehospitalized within 7 days after hospitalization (OR 0.61; 95% CI 0.40, 0.95) compared with neonates in the prelegislation period. Adjusted mean hospitalization costs increased $116 per delivery in the postlegislation period. CONCLUSIONS: After implementation of the Newborns' and Mothers' Health Protection Act legislation, maternal and newborn length of stay and maternal satisfaction with length of stay increased substantially, and hospitalization costs increased significantly. The strongest clinical benefit was observed among neonates who were at a lower risk for hospitalization within 1 week of discharge. With the exception of 30-day emergency room utilization, there was insufficient statistical power to test for differences among other maternal clinical outcomes.

Hospital Readmissions Among Children With H1N1 Influenza Infection.

OBJECTIVES: To describe readmissions among children hospitalized with H1N1 (influenza subtype, hemagglutinin1, neuraminidase 1) pandemic influenza and secondarily to determine the association of oseltamivir during index hospitalization with readmission. METHODS: We reviewed data from 42 freestanding children's hospitals contributing to the Pediatric Health Information System from May through December 2009 when H1N1 was the predominant influenza strain. Children were divided into 2 groups by whether they experienced complications of influenza during index hospitalization. Primary outcome was readmission at 3, 7, and 30 days among both patient groups. Secondary outcome was the association of oseltamivir treatment with readmission. RESULTS: The study included 8899 children; 6162 patients had uncomplicated index hospitalization, of whom 3808 (61.8%) received oseltamivir during hospitalization, and 2737 children had complicated influenza, of whom 1055 (38.5%) received oseltamivir. Median 3-, 7-, and 30-day readmission rates were 1.6%, 2.5%, and 4.7% for patients with uncomplicated index hospitalizations and 4.3%, 5.8%, and 10.3% among patients with complicated influenza. The 30-day readmission rates did not differ by treatment group among patients with uncomplicated influenza; however, patients with complicated index hospitalizations who received oseltamivir had lower all-cause 30-day readmissions than untreated patients. The most common causes of readmission were pneumonia and asthma exacerbations. CONCLUSIONS: Oseltamivir use for hospitalized children did not decrease 30-day readmission rates in children after uncomplicated index hospitalization but was associated with a lower 30-day readmission rate among children with complicated infections during the 2009 H1N1 pandemic. Readmission rates for children who had complicated influenza infection during index hospitalizations are high.

Decreasing hospital length of stay for bronchiolitis by using an observation unit and home oxygen therapy.

IMPORTANCE: Pediatric observation units (OUs) offer the opportunity to safely and efficiently care for common illnesses previously cared for in an inpatient setting. Home oxygen therapy (HOT) has been used to facilitate hospital discharge in patients with hypoxic bronchiolitis. It is unknown how implementation of a hospitalwide bronchiolitis treatment protocol promoting OU-HOT would affect hospital length of stay (LOS). OBJECTIVE: To test the hypothesis that using OU-HOT for bronchiolitis would decrease LOS. DESIGN AND SETTING: Retrospective cohort study at Primary Children's Medical Center, Salt Lake City, Utah. PARTICIPANTS: Uncomplicated bronchiolitis patients younger than 2 years admitted during the winter seasons of 2005 through 2011. INTERVENTIONS: Implementation of a new bronchiolitis care process encouraging use of an OU-HOT protocol. MAIN OUTCOME MEASURES: Mean hospital LOS, discharge within 24 hours, emergency department (ED) bronchiolitis admission rates and ED revisit/readmission rates, and inflation-adjusted cost. RESULTS: A total of 692 patients with bronchiolitis from the 2010-2011 bronchiolitis season were compared with 725 patients from the 2009-2010 season. Implementation of an OU-HOT protocol was associated with a 22.1% decrease in mean LOS (63.3 hours vs 49.3 hours, P < .001). Although LOS decreased during all 6 winter seasons, linear regression and linear quantile regression analyses for the 2005-2011 LOS data demonstrated a significant acceleration in the LOS decrease for the 2010-2011 season after implementation of the OU-HOT protocol. Discharges within 24 hours increased from 20.0% to 38.4% (P < .001), with no difference in ED bronchiolitis admission or ED revisit/readmission rates. After implementation of the OU-HOT protocol, the total cost per admitted case decreased by 25.4% ($4800 vs $3582, P < .001). CONCLUSIONS AND RELEVANCE: Implementation of an OU-HOT protocol for patients with bronchiolitis safely reduces hospital LOS with significant cost savings. Although widespread implementation has the potential for dramatic cost savings nationally, further studies assessing overall health care use and cost, including the impact on families and outpatient practices, are needed.

Neurologically intact children with an isolated skull fracture may be safely discharged after brief observation.

PURPOSE: The management of children presenting with an isolated skull fracture (ISF) posttrauma is highly variable. We sought to estimate the risk of neurologic deterioration in children with a Glasgow coma score (GCS) 15 and ISF to reduce unnecessary hospital admissions. METHODS: A retrospective review at a level I pediatric trauma referral center was conducted for patients with ISF on head computed tomography from 2003 to 2008. Patients were excluded for injury greater than 24 hours prior, GCS less than 15, intracranial pathology, significant fracture depression, or complex fractures involving facial bones or skull base. RESULTS: A total of 235 patients were identified with an ISF. The median age was 11 months, with falls accounting for 87% of the injuries. One hundred seventy-seven patients were admitted, and 58 patients were discharged from the emergency department after a period of observation (median, 3.3 hours). Median length of stay for those admitted to the hospital was 18.2 hours. One patient developed vomiting following overnight observation and a repeat computed tomography scan demonstrated a small extra-axial hematoma that required no intervention. The mean total costs for patients discharged from the emergency department were $291 vs $1447 for those admitted for observation (P < .001). CONCLUSION: Patients with a presenting GCS of 15 and an ISF can be safely discharged from the emergency department after a short period of observation if they are asymptomatic and have a reliable social environment. This could result in significant savings by eliminating inpatient costs.

Resource burden at children's hospitals experiencing surge volumes during the spring 2009 H1N1 influenza pandemic.

OBJECTIVES: The objective was to describe the emergency department (ED) resource burden of the spring 2009 H1N1 influenza pandemic at U.S. children's hospitals by quantifying observed-to-expected utilization. METHODS: The authors performed an ecologic analysis for April through July 2009 using data from 23 EDs in the Pediatric Health Information System (PHIS), an administrative database of widely distributed U.S. children's hospitals. All ED visits during the study period were included, and data from the 5 prior years were used for establishing expected values. Primary outcome measures included observed-to-expected ratios for ED visits for all reasons and for influenza-related illness (IRI). RESULTS: Overall, 390,983 visits, and 88,885 visits for IRI, were included for Calendar Weeks 16 through 29, when 2009 H1N1 influenza was circulating. The subset of 106,330 visits and 31,703 IRI visits made to the 14 hospitals experiencing the authors' definition of ED surge during Weeks 16 to 29 was also studied. During surge weeks, the 14 EDs experienced 29% more total visits and 51% more IRI visits than expected (p < 0.01 for both comparisons). Of ED IRI visits during surge weeks, only 4.8% were admitted to non-intensive care beds (70% of expected, p < 0.01), 0.19% were admitted to intensive care units (44% of expected, p < 0.01), and 0.01% received mechanical ventilation (5.0% of expected, p < 0.01). Factors associated with more-than-expected visits included ages 2-17 years, payer type, and asthma. No factors were associated with more-than-expected hospitalizations from the ED. CONCLUSIONS: During the spring 2009 H1N1 influenza pandemic, pediatric EDs nationwide experienced a marked increase in visits, with far fewer than expected requiring nonintensive or intensive care hospitalization. The data in this study can be used for future pandemic planning.

Hospital admission medication reconciliation in medically complex children: an observational study.

OBJECTIVE: To evaluate admission medication reconciliation in children with medically complex conditions (MCC) by determining the availability and accuracy of five information sources and characterising admitting order errors. DESIGN: Prospective quality improvement cohort study. SETTING: Tertiary care free-standing children's hospital in the Intermountain west, USA. PARTICIPANTS: 23 children with MCC identified from 219 admissions between 16 December 2004 and 7 January 2005. INTERVENTION: Medication reconciliation at hospital admission using information from five sources. MAIN OUTCOMES: The accuracy of information sources was determined by sensitivity and specificity compared with verified outpatient medication lists. Errors were determined by comparing admitting orders with reconciled inpatient medication lists and categorised by frequency, type and clinical risk. RESULTS: Children with MCC averaged 5.3 chronic medications. The reconciliation process took an average of 90 min. Availability/sensitivity/specificity respectively were parents 52%/0.75/0.96, pharmacy 61%/0.64/0.74, primary provider 43%/0.25/0.86, last admission electronic health record 87%/0.74/0.33 and admitting history 65%/0.31/0.94. Thirty-nine errors were identified in 182 admission medications (21%) including 17 omissions, affecting 13 patients (57%). The estimated clinical risk, if an adverse drug event had occurred, was serious or life-threatening in five instances. CONCLUSIONS: In children with MCC admitted at our institution during the study period, no medication information source was optimally available, sensitive and specific. Admitting order medication errors affected more than half of patients, the most common being omissions. Efforts to improve medication reconciliation at hospital admission in this population must account for availability and accuracy of information sources and medication omissions at the time of hospital admission.

Improving transitions of care at hospital discharge--implications for pediatric hospitalists and primary care providers.

Delays, omissions, and inaccuracy of discharge information are common at hospital discharge and put patients at risk for adverse outcomes. We assembled an interdisciplinary team of stakeholders to evaluate our current discharge process between hospitalists and primary care providers (PCPs). We used a fishbone diagram to identify potential causes of suboptimal discharge communication to PCPs. Opportunities for improvement (leverage points) to achieve optimal transfer of discharge information were identified using tally sheets and Pareto charts. Quality improvement strategies consisted of training and implementation of a new discharge process including: (1) enhanced PCP identification at discharge, (2) use of an electronic discharge order and instruction system, and (3) autofaxing discharge information to PCPs. The new discharge process's impact was evaluated on 2,530 hospitalist patient discharges over a 34-week period by measuring: (1) successful transfer of discharge information (proportion of discharge information sheets successfully faxed to PCPs), (2) timeliness (proportion of sheets faxed within 2 days of discharge), and (3) content (presence of key clinical elements in discharge sheets). Postintervention, success, and timeliness of discharge information transfer between pediatric hospitalists and PCPs significantly improved while content remained high.
