BackgroundLacerations account for a large number of ED visits. Is there a “golden period” beyond which lacerations should not be repaired primarily? What type of relationship exists between time of repair and wound infection rates? Is it linear or exponential? Currently, the influence of laceration age on the risk of infection in simple lacerations repaired is not clearly defined. We conducted this study to determine the influence of time of primary wound closure on the infection rate.MethodsThis is a prospective observational study of patients who presented to the Emergency Department (ED) with a laceration requiring closure from April 2009 to November 2010. The wound closure time was defined as the time interval from when the patient reported laceration occurred until the time of the start of the wound repair procedure. Univariate analysis was performed to determine the factors predictive of infection. A non-parametric Wilcoxon rank-sum test was performed to compare the median differences of time of laceration repair. Chi-square (Fisher's exact) tests were performed to test for infection differences with regard to gender, race, location of laceration, mechanism of injury, co-morbidities, type of anesthesia and type of suture material used.ResultsOver the study period, 297 participants met the inclusion criteria and were followed. Of the included participants, 224 (75.4%) were male and 73 (24.6%) were female. Ten patients (3.4%) developed a wound infection. Of these infections, five occurred on hands, four on extremities (not hands) and one on the face. One of these patients was African American, seven were Hispanic and two were Caucasian (p = 0.0005). Median wound closure time in the infection group was 867 min and in the non-infection group 330 min (p = 0.03).ConclusionsWithout controlling various confounding factors, the median wound closure time for the lacerations in the wound infection group was statistically significantly longer than in the non-infection group.

In our population, BT was inaccurate in predicting weight in 42% of children (underestimation in 158 children [29.4%] and overestimation weight in 68 children [12.6%]). However, the majority of discrepancies involved only 1 BT color zone. Emergency physicians should be aware of this discrepancy until more accurate methods become available.

IntroductionAccidents and assaults (homicides) are the leading causes of death among the youth of the United States, accounting for 53.3% of deaths among children aged 1 to19 years. Victim recidivism, defined as repeated visits to the emergency department (ED) as a victim of violent trauma, is a significantly growing public health problem. As 5-year mortality rates for recidivism are as high as 20%, it is important to determine whether victims with a history of violent trauma are at increased risk for fatal outcome with their next trauma. We hypothesized that victims of violent trauma who have had 1 prior ED visit for violent trauma will have increased odds of fatal outcome.MethodsA retrospective chart review was conducted for patients presenting with penetrating trauma to the ED from January 1, 1999 to December 31, 2009. All patients between the ages of 15 to 25 years who presented to the ED for any penetrating trauma were included. Patients with prior presentations for penetrating trauma were compared to those patients who were first-time presenters to determine the odds ratio of fatal outcome.ResultsOverall, 15,395 patients were treated for traumatic presentations. Of these, 1,044 met inclusion criteria. Demographically, 79.4% were Hispanic, 19.4% were African American, and 0.96% were Caucasian. The average age was 21 years, and 98% of the population was male. One hundred and forty-seven (14%) had prior presentations, and 897 (86%) did not. Forty of the 147 patients (27%) with prior presentations had a fatal outcome as compared to 29 patients of the 868 (3%) without prior presentations, with odds ratio of 10.8 (95% confidence interval, 6.4–18.1; Pearson χ2, P < 0.001). The 5-year mortality rate for those patients with fatal outcomes was calculated at 16.5%.ConclusionPatients who had prior ED visits for penetrating trauma were at greater risk for fatal outcomes compared to those with no prior visits. Therefore, trauma-related ED visits might offer an opportunity for education and intervention. This may help to prevent future fatalities.

Staging of a surge volume allows ED administrators to maintain a strong control of a multipatient event to ensure an effective response and appropriate use of limited resources. The implementation of the reorganized measures during the fall 2009 H1N1-related surge in patient's visits resulted in improved patient flow without significant increase in walkout and 7-day asthma revisit rates. Our strategies accommodated the surge of patients in the ED.

Background:It is believed to be the standard of care to obtain a blood culture in a child who is hospitalized for pneumonia. In recent years, many studies have questioned the utility of this practice in the presence of age appropriate immunization. We conducted this study to determine the current prevalence of bacteremia in children with uncomplicated pneumonia and the utility of obtaining blood cultures in these children.Objective:To evaluate the risk of bacteremia in hospitalized young children with pneumonia.Methods:This was a retrospective review from July 2003 until July 2008. The setting was the pediatric emergency department of an urban teaching hospital. The study population included children under 36 months of age who had been fully immunized and who had been hospitalized with radiographic evidence of uncomplicated pneumonia. Excluded were children who were currently using antibiotics or who had used antibiotics within the previous 48 hours, as well as children with immunodeficiency status such as sickle cell anemia, immunoglobulin deficiency, or children on steroid therapy.The radiologist’s interpretation of each chest radiograph was reviewed and recorded. The variables studied were age (in months), gender, race, birth history, pneumococcal vaccination status, appearance on arrival, temperature on arrival, respiratory rate, oxygen saturation, white blood cell (WBC) count, neutrophil count, band count, and urine culture. The chi-square test and logistic regression were used to analyze the data.Results:A blood culture was obtained in 535 children hospitalized with radiographic pneumonia. Bacteremia was present in 12 children (2.2%). All organisms isolated from the blood cultures were considered contaminants.Conclusion:Children hospitalized with uncomplicated pneumonia have a low rate of positive blood cultures. None of the variables studied predicted bacteremia. The absence of true-positive cultures among the organisms isolated suggests little value in obtaining blood cultures in children hospitalized due to uncomplicated pneumonia.

Objectives:The aims of this study were to determine and improve accuracy of the Broselow Tape (BT) in estimating children's weight by adding body habitus parameters.Methods: This cross-sectional study was conducted in an urban hospital pediatric clinic. Children up to 8 years old coming in for well-child visit were included. Children with acute illness or presence of any chronic condition potentially resulting in growth disturbance and out of BT height range were excluded. The following body habitus parameters were measured using the Centers for Disease Control and Prevention guidelines: actual weight, predicted weight using BT (BTW), mid-thigh circumference (MTC), body mass index, mid-arm circumference, and waist-to-hip ratio.Results: A total of 301 children were enrolled. Of these, 151 were male (50%). Hispanics constituted 160 (53.2%). There was a positive linear association between BTW and actual weight in the overall cohort (adjusted R 2 = 0.9164, P < 0.001). However, there was a difference in this association among children younger than 2 years and children older than 2 years (adjusted R 2 = 0.89 vs 0.4841). Incorporating MTC and/or waist circumference along with BTW in the model increased the accuracy, providing a better estimate of actual weight (adjusted R 2 = 0.94, P < 0.001). Conclusions:We conclude that there might be inaccuracies in the weight predicted by BT in our patient population, especially those weighing more than 15 kg and older than 2 years. Our study also demonstrates that MTC correlates closely with the actual weight and could be used in addition to BT for more accurate weight estimation.
