RESUMO
OBJECTIVE: Respiratory failure caused by acute lung injury or acute respiratory distress syndrome is associated with significant morbidity in children. Enteral nutrition enriched with eicosapentaenoic acid, γ-linolenic acid and antioxidants (eicosapentaenoic acid + γ-linolenic acid) can safely modulate plasma phospholipid fatty acid profiles, reduce inflammation, and improve clinical outcomes in adults. There is little information regarding the use of enteral eicosapentaenoic acid + γ-linolenic acid to modulate plasma phospholipid fatty acid profiles in children. We sought to determine if continuous feeding of enteral nutrition containing eicosapentaenoic acid, γ-linolenic acid, and antioxidants was feasible in critically ill children with acute lung injury or acute respiratory distress syndrome. We further evaluated the impact of such an approach on the alteration of plasma phospholipid fatty acid concentrations. DESIGN: Prospective, blinded, randomized, controlled, multicenter trial. SETTING: PICU. PATIENTS: Twenty-six critically ill children (age 6.2 ± 0.9 yr, PaO2/FIO2 185 ± 15) with the diagnosis of acute lung injury or acute respiratory distress syndrome. INTERVENTIONS: Mechanically ventilated children received either eicosapentaenoic acid + γ-linolenic acid or a standard pediatric enteral formula. Clinical, biochemical, plasma fatty acid, and safety data were assessed at baseline, study days 4 and 7. MEASUREMENTS AND MAIN RESULTS: At baseline, there were no significant differences in the two study groups. Both groups met enteral feeding goals within 30 hrs and had similar caloric delivery. There were no differences in formula tolerance as measured by serum chemistries, liver and renal function, and hematology studies after 7 days of feeding either eicosapentaenoic acid + γ-linolenic acid or pediatric enteral formula. On study day 4 and 7, plasma phospholipid fatty acid profiles in the eicosapentaenoic acid + γ-linolenic acid group showed a significant increase in anti-inflammatory circulating markers. CONCLUSIONS: Providing enteral nutrition with eicosapentaenoic acid + γ-linolenic acid to critically ill children with lung injury was feasible and caloric goals were met within 30 hrs. This feeding protocol effectively modulated plasma phospholipid fatty acid concentrations to reflect an anti-inflammatory profile. This study provides data to inform future outcome studies using enteral eicosapentaenoic acid + γ-linolenic acid in children with lung injury.

OBJECTIVES: To describe the use of an adverse event detection system to identify, characterize, and categorize preventable versus nonpreventable hypoglycemia AEs in PICUs and cardiac ICUs. DESIGN: Retrospective observational study. SETTING: PICU and cardiac ICU of a tertiary pediatric hospital. SUBJECTS: All hypoglycemia triggers generated over a 3-year period. INTERVENTIONS: All hypoglycemia triggers generated via an electronic health record-driven surveillance system were investigated to determine if they represented a true adverse event and if that event was preventable or nonpreventable. Clinical and demographic variables were analyzed to identify characteristics of patients who developed a preventable or nonpreventable hypoglycemia adverse event. MEASUREMENTS AND MAIN RESULTS: There were 197 hypoglycemia adverse events in 90 patients. Thirty percent of the adverse events in the PICU and 36% of the adverse events in the cardiac ICU were characterized as preventable. Of the adverse events, 118 (59.9%) necessitated an intravenous dextrose bolus. No adverse events were associated with reporting of symptoms of hypoglycemia including apnea, altered mental status, or seizures. Events were more likely to be preventable (p < 0.001) if the patient was receiving only parenteral sources of nutrition (intravenous fluids or total parenteral nutrition). Controlling for weekends and holidays, adverse events associated with sole parenteral nutrition source had an increased odds ratio of 9.5 (95% confidence interval: 2.8-31.9) of being preventable. Stratifying by ICU, cardiac ICU events occurring on a weekend or holiday were more likely to be preventable (p = 0.001). Stratifying by unit and controlling for parenteral nutrition source, adverse events in the cardiac ICU occurring on weekends or holidays had an increased odds ratio of 11.6 (95% confidence interval: 2.7-50.2) of being preventable. CONCLUSIONS: Preventable hypoglycemia adverse events are associated with patients receiving sole parenteral sources of nutrition in both the PICU and cardiac ICU. In the cardiac ICU, there is an association between weekend and holiday time periods and the development of preventable hypoglycemia adverse events.

PURPOSE: To evaluate, in a phase III, single-arm study, the safety and efficacy of the thrombolytic agent tenecteplase in restoring function to dysfunctional central venous catheters (CVCs). MATERIALS AND METHODS: Pediatric and adult patients with dysfunctional CVCs were eligible to receive as much as 2 mL (2 mg) of intraluminal tenecteplase, which was left to dwell in the CVC lumen for a maximum of 120 minutes. If CVC function was not restored at 120 minutes, a second dose was instilled for an additional 120 minutes. RESULTS: Tenecteplase was administered to 246 patients. Mean patient age was 44 years (range, 0-92 y); 72 patients (29%) were younger than 17 years of age. Chemotherapy was the most common reason for catheter insertion. Restoration of CVC function was achieved in 177 patients (72%) within 120 minutes after the first dose. After instillation of a maximum of two doses of tenecteplase, CVC function was restored in 200 patients (81%), with similar frequencies in pediatric (83%) and adult (80%) patients. Adverse events (AEs) were reported in 31 patients (13%); fever (2%), neutropenia (1%), and nausea (0.8%) were most common. One serious AE, an allergic hypersensitivity reaction, was judged to be related to tenecteplase and/or a chemotherapeutic agent that the patient was receiving concurrently. CONCLUSIONS: Consecutive administration of one or two doses of tenecteplase into CVCs showed efficacy in the restoration of catheter function in patients with dysfunctional CVCs.

OBJECTIVES: We investigated the effect of heliox-powered albuterol therapy on hospital length of stay and clinical status in children with moderate to severe status asthmaticus. DESIGN: Prospective, randomized, placebo-controlled trial. SETTING: Twenty-five-bed pediatric intensive care unit at an academic children's medical center. PATIENTS: Forty-two children (2-21 yrs of age) with moderate to severe status asthmaticus. INTERVENTIONS: Patients were randomized to receive either heliox-powered nebulized albuterol or air/oxygen-powered nebulized albuterol (placebo) until they were transitioned to albuterol delivered by a metered dose inhaler. MEASUREMENTS AND MAIN RESULTS: Clinical asthma scores were recorded on enrollment and every 4 hrs thereafter. Patients in the heliox group (n = 22) and the control group (n = 20) had similar ages (mean +/- sem: 88 +/- 9.9 vs. 98 +/- 11.1 months, respectively; p = .51), time to study enrollment (618 +/- 70.4 vs. 597 +/- 84.1 mins, respectively; p = .72), and clinical asthma scores at study entry (5.9 +/- 0.2 vs. 5.7 +/- 0.3, respectively; p = .72). There were no significant differences between groups in time to eligibility to hospital discharge (66.2 +/- 8.7 vs. 63.4 +/- 8.6 hrs, respectively; p = .61), time to clinical asthma score <3 (22 +/- 2.8 vs. 21.2 +/- 5.3 hrs, respectively; p = .27), or time to eligibility for intensive care unit discharge (34.4 +/- 6.8 vs. 33.3 +/- 8.2 hrs, respectively; p = .64). There were no significant differences in adverse events between groups. CONCLUSIONS: Despite the previously demonstrated effects of heliox on improved aerosol particle delivery into the distal airways, heliox-powered nebulized albuterol therapy for children admitted to the hospital with moderate to severe status asthmaticus does not shorten hospital length of stay or hasten rates of clinical improvement when compared with air/oxygen-powered nebulized albuterol.

OBJECTIVE: To describe a young child with complex fibropurulent pericarditis who was successfully treated with intrapericardial recombinant tissue plasminogen activator. DESIGN: Individual case report. SETTING: Pediatric intensive care unit of a tertiary children's hospital. PATIENT: A 4-month-old Asian girl with Staphylococcus aureus septic shock who later developed a loculated fibropurulent pericardial effusion that was refractory to management with a subxiphoid percutaneous pericardial drainage catheter. INTERVENTIONS: Three doses of intrapericardial tissue plasminogen activator were administered at 12-hr intervals, allowed to dwell for 2 hrs, and subsequently drained via low continuous suction. MEASUREMENTS AND MAIN RESULTS: Immediately after intrapericardial tissue plasminogen activator was administered via a percutaneous pericardial drainage catheter, the patient had an increase in pericardial fluid drainage and resolution of a complex fibropurulent pericardial effusion. Pericardial fluid drainage ceased and then increased to 122 mL, 270 mL, and 80 mL of fluid, respectively, after each of the three doses of intrapericardial tissue plasminogen activator. Serial echocardiography confirmed the initial presence of the effusion, the subsequent loculated nature of the effusion, and ultimate resolution of the effusion after tissue plasminogen activator. The patient survived to hospital discharge without cardiac dysfunction. CONCLUSIONS: The fibrinolytic effect of tissue plasminogen activator therapy promotes the resolution of complex fibropurulent pericardial effusions refractory to traditional pericardial drainage via percutaneous catheter and suction. Use of intrapericardial tissue plasminogen activator may preclude the need for surgical intervention in fibropurulent pericarditis.

OBJECTIVE: To assess the impact of calfactant (a modified natural bovine lung surfactant) in immunocompromised children with acute lung injury and to determine the number of patients required for a definitive clinical trial of calfactant in this population. DESIGN: Post hoc analysis of data from a previous randomized, control trial. SETTING: Tertiary care pediatric intensive care units. PATIENTS: All children, defined as immunocompromised, enrolled in a multicenter, masked, randomized, control trial of calfactant for acute lung injury conducted between July 2000 and July 2003. INTERVENTIONS: Patients received either an intratracheal instillation of calfactant or an equal volume of air placebo in a protocolized manner. MEASUREMENTS AND MAIN RESULTS: Eleven of 22 (50%) calfactant-treated patients died when compared with 18 of 30 (60%) placebo patients (absolute risk reduction 10.0%, 95% confidence interval [CI] -17.3, 37.3). Among the 23 patients with an initial oxygen index (OI) >/=13 and =37, 44% (4 of 9) of calfactant-treated patients died in comparison with 71% (10 of 14) of placebo (absolute risk reduction 27.0%, 95% CI -13.2, 67.2). Only 33% (3 of 9) of calfactant patients died before intensive care discharge in comparison with 71% (10 of 14) of placebo (absolute risk reduction 38.1%, 95% CI -0.7, 76.9). Calfactant therapy was associated with improved oxygenation in these 23 patients. Using an OI entry criterion of (13 = OI = 37), stratifying on the presence of hematopoietic stem cell transplantation, and accepting the 27% difference in mortality observed in this analysis, 63 patients would be required in each arm of a randomized, control trial to demonstrate a significant effect of calfactant on mortality in this patient population assuming a two-sided alpha of 0.05 and a power of 0.85. CONCLUSIONS: These preliminary data suggest a potential benefit of calfactant in this high-risk population. A clinical trial powered to appropriately assess these findings seems warranted and feasible.

BACKGROUND: For the 1.4 million emergency department (ED) visits for traumatic brain injury (TBI) annually in the United States, computed tomography (CT) may be over utilized. The Pediatric Emergency Care Applied Research Network developed 2 prediction rules to identify children at very low risk of clinically important TBI. We implemented these prediction rules as decision support within our electronic health record (EHR) to reduce CT. OBJECTIVE: To test EHR decision support implementation in reducing CT rates for head trauma at 2 pediatric EDs. METHODS: We compared monthly CT rates 1 year before [preimplementation (PRE)] and 1 year after [postimplementation (POST)] decision support implementation. The primary outcome was change in CT use rate over time, measured using statistical process control charts. Secondary analyses included multivariate comparisons of PRE to POST. Balancing measures included ED length of stay and returns within 7 days after ED release. RESULTS: There were 2,878 patients with head trauma (1,329 PRE and 1,549 POST) included. Statistical process control charts confirmed decreased CT rates over time POST that was not present PRE. Secondary statistical analyses confirmed that CT scan utilization rates decreased from 26.8% to 18.9% (unadjusted Odds Ratio [OR], 0.64; 95% Confidence Interval [CI], 0.53 -0.76; adjusted OR, 0.71; 95% CI, 0.58 -0.86). Length of stay was unchanged. There was no increase in returns within 7 days and no significant missed diagnoses. CONCLUSIONS: Implementation of EHR-integrated decision support for children with head trauma presenting to the ED is associated with a decrease in CT utilization and no increase in significant safety events.
RESUMO
BACKGROUND: Intraluminal occlusion is common in children with central venous catheters (CVCs). Although multiple factors predispose CVCs to occlusion, reflux of blood is frequently implicated. We hypothesized that use of either a single-valve or positive-pressure-valve needleless connector device would reduce CVC occlusion rates in comparison to a standard device. We further hypothesized that saline would be as effective as heparinized saline flush in preventing occlusion and infection. METHODS: CVC lumens were prospectively capped with 1 of 3 needleless connector devices in a 4-group design. Group 1 lumens were capped with a standard device, group 2 with a single-valve device, group 3 with a positive-pressure-valve device flushed with heparinized saline, and group 4 with a positive-pressure-valve device flushed with saline. Data were obtained regarding occlusion and infection rates and user satisfaction. RESULTS: Three hundred sixty children with 599 CVC lumens completed the study. Complete occlusion occurred in 19/150 (12.7%) lumens in group 1 in comparison to 2/150 (1.3%) in group 2, 5/149 (3.4%) in group 3, and 6/150 (4%) in group 4 (p < .05). There was a trend toward a 2-fold greater infection rate in group 4. User satisfaction was higher in groups 2, 3, and 4 than group 1 (p < .05). CONCLUSIONS: CVCs capped with a single-valve or positive-pressure-valve needleless connector device have lower complete catheter occlusion rates than those capped with a standard device. Heparinized saline flush affords no advantages over saline in reducing occlusion rate; however, there was a trend toward lower infection rate with the use of heparinized saline.

OBJECTIVE: : To determine whether infrared tympanic thermometry (ITT) measurements more accurately reflect core body temperatures than axillary, forehead, or rectal measurements during fever cycles in children. DESIGN: : Prospective cohort study. SETTING: : Pediatric and cardiac intensive care units at a tertiary care children's hospital. PATIENTS: : Critically ill children <7 yrs of age with indwelling bladder catheters. INTERVENTIONS: : Simultaneous temperatures were recorded during both febrile and nonfebrile periods using ITT, indwelling bladder (core), axillary, forehead, and indwelling rectal measurements in 36 children. MEASUREMENTS AND MAIN RESULTS: : Overall ITT measurements were 0.03 +/- 1.43 degrees F less than core temperature measurements. In comparison, rectal, forehead, and axillary measurements averaged 0.62 +/- 1.44, 0.56 +/- 1.81, and 1.25 +/- 1.73 degrees F less than core temperature measurements. ITT measurements had better agreement with core measurements during increasing and decreasing temperature cycles. Receiver operating characteristic analysis performed on increasing and decreasing temperature cycle data revealed that ITT measurements performed well, with an area under the curve of 0.855 (95% confidence interval, 0.797-0.913) in comparison with rectal measurement area under the curve of 0.777 (95% confidence interval, 0.701-0.853), forehead measurement area under the curve of 0.710 (95% confidence interval, 0.715-0.888), and axillary measurement area under the curve of 0.664 (95% confidence interval, 0.579-0.750). CONCLUSIONS: : ITT measurements more accurately reflect core temperatures than any other measurement site during febrile and nonfebrile periods in children. ITT measurements are a reproducible and relatively noninvasive substitute for bladder or rectal measurements in febrile children.

There is little published information describing standards of practice in the placement, use, and maintenance of peripherally inserted central catheter (PICC) devices in children. A Web-based survey tool was designed to query these issues, and 72 intravenous therapy nurses from 72 hospitals provided complete responses to the survey. The respondents were predominantly (81%) from healthcare organizations inserting 40 or fewer PICC devices per month. These hospitals were equally divided in using 0.9% sodium chloride (USP) (saline) or heparinized saline flush to maintain patency, whereas 76% used catheters for blood sampling. Flushing and blood sampling practices were not related to catheter occlusion rates. From their survey, the authors conclude that the standards of practice for 3-Fr PICC devices, the most commonly used for children, are quite variable and in need of standardization for this specific population.

Computerized provider order entry (CPOE) and clinical decision support improve medication prescribing safety in adults. However, effective therapy for children requires dosing based on circulating medication levels. We examined the introduction of a computerized corollary order for aminoglycoside blood level monitoring. The study was divided into baseline (BP) and corollary order (CP) periods. In the CP, we implemented a workflow-integrated reminder to order blood levels and presented this to the clinician during each aminoglycoside ordering session. Appropriate laboratory monitoring was 128/159 (80.5%) courses in the BP and 146/177 (82.5%) courses in the CP. Thus introduction of the order did not significantly improve laboratory monitoring rates, nor did it result in a reduction in the rate of either toxic or subtherapeutic levels. However, aminoglycoside corollary orders may have an important role in institutions where pharmacists are not actively involved in monitoring therapy.

OBJECTIVE: To compare the efficacy of theophylline, terbutaline, or theophylline combined with terbutaline treatment in critically ill children with status asthmaticus who are already receiving continuous nebulized albuterol and intravenous corticosteroids. DESIGN: Randomized, prospective, controlled, double-blind trial. SETTING: Pediatric intensive care unit of a tertiary-care children's medical center. PATIENTS: Forty critically ill children between the ages of 3 and 15 yrs with impending respiratory failure secondary to status asthmaticus. INTERVENTIONS: All patients received intravenous methylprednisolone and continuous nebulized albuterol. The three study groups received theophylline plus placebo (group 1), terbutaline plus placebo (group 2), or theophylline and terbutaline together (group 3). MEASUREMENTS AND MAIN RESULTS: Differences in baseline characteristics, change in clinical asthma score over time, length of pediatric intensive care unit stay, and incidence of adverse events were determined. The three study groups were similar in age, gender, race, asthma severity, and treatment. There were no differences in clinical asthma score over time, length of pediatric intensive care unit stay, or incidence of adverse events between the three groups, with the exception of a higher incidence of nausea in children in group 3. The median hospital cost of medication and theophylline blood levels was significantly lower in group 1 compared with groups 2 and 3 (280 US dollars vs. 3,908 US dollars vs. 4,045 US dollars, respectively, p < .0001). CONCLUSIONS: Theophylline, when added to continuous nebulized albuterol therapy and intravenous corticosteroids, is as effective as terbutaline in treating critically ill children with status asthmaticus. The addition of theophylline to baseline therapy is more cost-effective when compared with terbutaline alone or terbutaline and theophylline together. Theophylline should be considered for use early in the management of critically ill asthmatic children.

OBJECTIVE: To determine whether hsp70 is elevated in the plasma of children with septic shock. DESIGN: Cohort study. SETTING: Two academic, tertiary pediatric intensive care units. PATIENTS: Ninety-four children admitted to the pediatric intensive care unit with septic shock and 24 control children undergoing elective surgical procedures. INTERVENTIONS: Venous or arterial blood sampling. MEASUREMENTS AND MAIN RESULTS: Children admitted to the pediatric intensive care unit with a diagnosis of septic shock were enrolled in the study following written informed consent. The control group consisted of healthy children undergoing elective surgical procedures. Blood samples from children in the septic shock or control groups were obtained within 24 hrs of admission to the pediatric intensive care unit or during the preoperative visit. Samples were collected, centrifuged, and stored at -70 degrees C. The hsp70 levels were measured using a commercially available enzyme-linked immunosorbent assay. Results were analyzed by Wilcoxon's rank sum test. Extracellular hsp70 levels in children with septic shock were significantly elevated compared with control patients (51.6 ng/mL vs. 8.1 ng/mL, respectively, p = .0004). CONCLUSIONS: Extracellular hsp70 levels are significantly elevated in children with septic shock compared with controls. Given the newly described cell signaling properties of hsp70, these data suggest that extracellular hsp70 may play a role in the host response during septic shock.

BACKGROUND: The peripherally inserted central catheter (PICC) is commonly used in children for medication and fluid administration. In addition, PICCs are used occasionally for blood sampling as an alternative to venipuncture. Blood sampling from these catheters carries the hypothetical risk of catheter occlusion caused by blood remaining in the catheter, and this practice is not supported by PICC manufacturers. Children often undergo multiple needle punctures, which are associated with pain, anxiety, and dissatisfaction with care. The authors hypothesized that blood sampling through 3-Fr PICC devices is effective and safe for children. METHODS: After placement of a 3-Fr PICC, all the children were sequentially enrolled in one of two groups. The control group included patients that had 3-Fr PICC devices without blood sampling. The blood sampling group included patients with 3-Fr PICC devices through which blood samples were obtained. Demographic data, PICC placement and sampling data, infusate composition, catheter occlusion, mechanical complications, and blood stream infections were recorded. The primary outcome variable was the difference in occlusion rates between the two groups. RESULTS: The analysis included 204 children with 3-Fr PICCs (120 in the blood sampling group and 84 in the control group) who had a mean age, 117.7 +/- 4.9 months. The mean PICC duration was 15.6 +/- 1.0 days. Blood sampling was successful more than 98% of the time from all blood sampling group catheters, with a mean of 4.4 +/- 0.5 samples removed from each catheter. There was a higher occlusion rate in the blood sampling group. However, this result did not reach statistical significance. There were no significant differences between the groups in terms of infection or mechanical complication rates. CONCLUSIONS: Blood sampling is feasible and effective through 3-Fr PICC devices in children. This practice is not associated with a significant increase in occlusion, infection, or mechanical complication rates.

CONTEXT: Despite evidence that patients with acute lung injury (ALI) have pulmonary surfactant dysfunction, trials of several surfactant preparations to treat adults with ALI have not been successful. Preliminary studies in children with ALI have shown that instillation of a natural lung surfactant (calfactant) containing high levels of surfactant-specific protein B may be beneficial. OBJECTIVE: To determine if endotracheal instillation of calfactant in infants, children, and adolescents with ALI would shorten the course of respiratory failure. DESIGN, SETTING, AND PATIENTS: A multicenter, randomized, blinded trial of calfactant compared with placebo in 153 infants, children, and adolescents with respiratory failure from ALI conducted from July 2000 to July 2003. Twenty-one tertiary care pediatric intensive care units participated. Entry criteria included age 1 week to 21 years, enrollment within 48 hours of endotracheal intubation, radiological evidence of bilateral lung disease, and an oxygenation index higher than 7. Premature infants and children with preexisting lung, cardiac, or central nervous system disease were excluded. INTERVENTION: Treatment with intratracheal instillation of 2 doses of 80 mL/m2 calfactant or an equal volume of air placebo administered 12 hours apart. MAIN OUTCOME MEASURES: Ventilator-free days and mortality; secondary outcome measures were hospital course, adverse events, and failure of conventional mechanical ventilation. RESULTS: The calfactant group experienced an acute mean (SD) decrease in oxygenation index from 20 (12.9) to 13.9 (9.6) after 12 hours compared with the placebo group's decrease from 20.5 (14.7) to 15.1 (9.0) (P = .01). Mortality was significantly greater in the placebo group compared with the calfactant group (27/75 vs 15/77; odds ratio, 2.32; 95% confidence interval, 1.15-4.85), although ventilator-free days were not different. More patients in the placebo group did not respond to conventional mechanical ventilation. There were no differences in long-term complications. CONCLUSIONS: Calfactant acutely improved oxygenation and significantly decreased mortality in infants, children, and adolescents with ALI although no significant decrease in the course of respiratory failure measured by duration of ventilator therapy, intensive care unit, or hospital stay was observed.

BACKGROUND AND OBJECTIVES: Sickle cell disease (SCD) is a blood disorder affecting many US children that is often associated with hospital readmission. Although previous studies have reported on the clinical factors that influence readmission risk, potential geographic factors have not been fully investigated. The goal of this study was to investigate the importance of geographic risk factors and to confirm previously derived clinical risk factors that influence readmissions for SCD pain crises. METHODS: Retrospective analyses were performed on pediatric inpatients with sickle cell crises at a single center. Readmission rates and risk factors were assessed. Geospatial analysis was conducted on point variables that represented health service access, and multivariable logistic regression models were constructed. RESULTS: The study identified 373 patients experiencing sickle cell crises, with 125 (33.5%) having at least one 30-day readmission. Age (mean difference: 2.2 years; P<0.001), length of stay (median difference: 1 day; P<.001), admission pain score>7 of 10 (odds ratio [OR]: 2.21; P<0.01), discharge pain score>4 of 10 (OR: 2.098; P<.01), living within 5 miles of the center's main hospital (OR: 0.573; P=.04), and >3 hospital utilizations in the previous 12 months (OR: 5.103; P<.001) were identified as potential indicators of 30-day readmission risk. Logistic regression models for 30-day readmissions yielded similar results. CONCLUSIONS: Increased age, high admission and discharge pain scores, decreased length of stay, and increased hospital utilizations were found to be associated with an increased risk of readmission for sickle cell crisis. Patient's residence was also found to be a significant risk indicator, supporting the utility of geospatial analysis in assessing readmission risk.

Medication shortages pose serious problems in health care. This study examines the impact of a computer-based reminder in addressing a national methylprednisolone shortage. An alert was designed and implemented in a computerized order entry platform at a children's hospital. The alert informed physicians of the shortage and provided an alternative prescribing pathway. Data regarding the number and type of parenteral corticosteroid prescriptions were collected for a one-month period before and after the alert was implemented. The alert resulted in a 55% relative reduction in methylprednisolone use and an average reduction of more than three orders each day. Dexamethasone and hydrocortisone, the recommended alternative medications, increased in use by 12% and 49%, respectively. The alert resulted in a $36,552 annualized cost reduction to the institution. Similar alert applications have great potential for effectively altering physician prescribing behavior.

Accidental poisoning with household cleaning products can pose significant risks to children. Exposure to granular laundry detergents accounts for a number of calls each year to poison control centers, though few of these exposures result in hospitalization. While caustic gastrointestinal injury resulting from ingestion of these highly alkaline cleaning agents is well-recognized, few reports address the potential damage to the respiratory tract that can occur following ingestion or inhalation of granular laundry detergent. We present a previously healthy 1-year-old who presented to the emergency department with Late-onset stridor and increased work of breathing following presumed inhalation of granular laundry detergent. Parents, primary care providers, and emergency department physicians need to be aware of the potential toxicity of these widely used household products.
