Vital signs among emergency department trauma patients in the setting of alcohol or drug use.

INTRODUCTION: The incidence of alcohol use among trauma patients has been estimated at 19-55%. This study was undertaken to identify any relationship between vital signs and alcohol and drug use among Emergency Department (ED) patients with trauma. METHODS: In this retrospective case control study, eligible subjects included trauma patients ages 18 and over, with trauma and drug or alcohol use, between 2018 and 2022. The control group was comprised of trauma patients ages 18 and over, with trauma and no drug or alcohol use, who were matched by Injury Severity Score (ISS). Vital signs on ED arrival were compared among patients with and without alcohol use, and with and without recreational drug use. RESULTS: Among 16,159 eligible trauma subjects, 5,323 had tests available for drugs and alcohol of whom 2,750 had complete ISS and vital signs data. 684 subjects were identified with alcohol intoxication, 707 subjects were identified with recreational drug use. Patients with alcohol use had lower mean systolic blood pressure (Mean=133, SD=26.7), compared to patients without alcohol use (Mean=143, SD=29.4) (p < 0.001). Patients with alcohol use had higher mean heart rate (Mean=93, SD=19.9) compared to patients without alcohol use (Mean=91, SD=19.7) (p = 0.01). Patients with recreational drug use had lower mean systolic blood pressure (Mean=137, SD=28.5) compared to patients without drug use (Mean=143, SD=29.6) (p < 0.001). Patients with drug use had higher mean heart rate (Mean=94, SD=22.8), compared to patients without drug use (Mean=91, SD=20.0) (p = 0.002). Cannabinoids were associated with lower SBP (Case Mean=136 (25.4) vs. Control Mean=141 (31.0), p = 0.009). Opioids were associated with lower SBP (Case Mean=138 (28.0) vs. Control Mean=145 (29.4), p = 0.01). Benzodiazepines were associated with increased HR and decreased SBP and RR. CONCLUSIONS: There appear to be no clinically relevant differences in vital signs among trauma patients with drug use and/or alcohol use, compared to patients without drug or alcohol use. Abnormal vital signs should not be prematurely attributed solely to acute substance intoxication before fully evaluating for associated traumatic injuries.

Demographics and Reported Symptoms Associated With Marijuana Use Among Adolescents and Young Adults.

Purpose Marijuana use has been increasing in the adolescent population. Our objective was to examine the prevalence of marijuana use among a sample of adolescents and young adults, determine an association with risk-taking behaviors, identify reported medical symptoms, and delineate common beliefs about marijuana use. Methods A questionnaire was administered to a sample of patients aged between 12 and 23 years old presenting to the emergency department of Penn State Hershey Medical Center, Hershey, Pennsylvania. Data were stratified by marijuana users and non-users, and further stratified by traditional (vape, pipe, edibles) and non-traditional (oils/concentrates, topical creams) use. Results The analysis was based on 200 questionnaires. Thirty-nine percent (n=78) reported marijuana use. Marijuana users were more likely to report previous sexual intercourse (79.5% vs. 32.8%; p=<0.0001), as well as the use of alcohol (50.0% vs. 10.7%; p=<0.0001), cigarettes (41% vs. 8.2%; p=<0.0001), prescription pain medications (20.5% vs. 4.1%; p=0.002), and cocaine (14.1% vs. 0.8%; p=0.0017). Users more likely reported texting while driving (41.0% vs. 13.1%; p=0.005) and experienced physical or electronic victimization due to bullying (43.6% vs. 19.7%; p=0.002). Users were more likely to report gastroesophageal reflux disease (GERD), attention deficit disorder (ADD), anxiety, and depression. The most common symptoms associated with marijuana use were anxiety (65.4%), headache (61.6%), nausea/vomiting (53.8%), cough (51.3%), and abdominal pain (47.4%). Sixty-nine percent of respondents believed marijuana was "safer than other drugs". Conclusion Based on our sample, we identified risk-taking behaviors, medical symptoms, and beliefs associated with marijuana use. Healthcare professionals may use these data to provide screening and anticipatory guidance to adolescents who use marijuana and consider marijuana use in their differential diagnosis.

Using a Bougie With C-MAC Video Laryngoscopy Did Not Improve First-Attempt Intubation Success Rates in Critical Care Air Transport.

OBJECTIVE: Studies have shown a bougie improves first-attempt success rates when used in combination with direct laryngoscopy during the initial attempt. The purpose of this study was to determine whether the use of a bougie in combination with C-MAC (Karl Storz, Tuttlingen, Germany) improves first-attempt success rates of endotracheal intubation (ETI) compared with C-MAC with a traditional stylet. METHODS: This study is a retrospective chart review using data collected on 371 intubations completed by a single air medical service using the C-MAC laryngoscope and either a bougie or a stylet. RESULTS: The overall success rate using C-MAC for ETI with either a bougie or a stylet was 83%. There was no statistically significant difference between first-attempt successful intubations using C-MAC and a bougie (82%) or a stylet (86%) (χ1 = 0.871, P = .351). There was no statistically significant difference between laryngoscopy grade and the number of attempts that resulted in a successful intubation (χ1 = 0.743, P = .7). CONCLUSION: There was no difference between first-attempt success rates using video laryngoscopy with a bougie, overall intubation success rates, or difficult intubation success rates compared with video laryngoscopy with a stylet, indicating that the purpose of a bougie as a rescue device did not hold true in the prehospital setting of our critical care air medical service.

Zone I Revision Finger Amputations Performed in the Emergency Department Compared With Those Performed in the Operating Room.

Finger amputations are commonly encountered. These may be revised in the emergency department (ED) or the operating room (OR). Previous studies have demonstrated the cost-effectiveness associated with procedures performed in the ED. Patient outcomes have not been described. We retrospectively reviewed patients who presented to our level 1 trauma center with a traumatic partial or complete finger amputation through flexor tendon zone I. All were treated with revision amputation performed in either the ED or the OR between January 2012 and December 2017. A total of 172 patient charts were included. Ninety-three of the revision amputations were performed in the ED, while 79 were performed in the OR. There was no difference in age, race, sex, having a manual labor job, medical comorbidities, or mechanism of injury between the groups. Compared with procedures performed in the ED, procedures performed in the OR had a higher rate of delayed healing, a longer stay in the hospital, and a higher referral to therapy postoperatively. Length of follow-up and number of follow-up visits were not statistically different based on location of procedure. There was no difference in post-procedural infection rate or need for revision procedure between the groups. Our data support the efficacy of performing revision amputation procedures in the ED. Recorded patient complications and subsequent treatment after revision amputations performed in the ED vs the OR were comparable. Those performed in the ED potentially decrease the burden placed on the patient and the health care system. [Orthopedics. 202x;4x(x):xx-xx.].

Referrals for Pediatric Appendicitis to a Tertiary Care Children's Hospital.

OBJECTIVES: This study aimed to analyze pediatric referrals for definite or possible appendicitis, to compare clinical predictors and laboratory values between patients with and without a final diagnosis of appendicitis, and to determine the accuracy of prereferral diagnostic interpretations of computed tomography scans, ultrasound, and magnetic resonance imaging modalities. METHODS: We conducted a retrospective analysis of pediatric patients referred from 2015 to 2019 to a tertiary care children's emergency department with definitive or possible appendicitis. Data abstracted included patient demographics, clinical symptoms, physical examination findings, laboratory results, and diagnostic imaging findings (by the referring center and the pediatric radiologist at the accepting center). An Alvarado and Appendicitis Inflammatory Response (AIR) score was calculated for each patient. RESULTS: Analysis was performed on 381 patients; 226 (59%) had a final diagnosis of appendicitis. Patients with appendicitis were more likely to have symptoms of nausea ( P < 0.0001) and vomiting ( P < 0.0001), have a higher mean temperature ( P = 0.025), right lower quadrant abdominal pain to palpation ( P = <0.0001), rebound tenderness ( P < 0.0001), a higher mean Alvarado score [5.35 vs 3.45 ( P < 0.0001)], and a higher mean AIR score [4.02 vs 2.17 ( P < 0.0001)]. Of the 97 diagnostic images initially interpreted as appendicitis by the referring center, 10 (10.3%) were read as no evidence of appendicitis. Of the 62 diagnostic images initially interpreted as "possible appendicitis" by the referring center, 34 (54.8%) were read as no evidence of appendicitis. Of those diagnostic images initially interpreted as "appendicitis" or "possible appendicitis" by the referring center, 24/89 (27.0%) of computed tomography scans, 17/62 (27.4%) of ultrasounds, and 3/8 (37.5%) of magnetic resonance imaging results were read as no evidence of appendicitis. CONCLUSIONS: Usage of established scoring algorithms, such as Alvarado and AIR, may decrease the unnecessary cost of diagnostic imaging and transfer to tertiary care. Virtual radiology consultations may be 1 potential solution to improve the referral process for pediatric appendicitis if initial interpretation is uncertain.

Returns After Discharge From the Emergency Department Observation Unit: Who, What, When, and Why?

INTRODUCTION: The number of emergency department observation units (EDOU) and observation stays has continued to increase. Despite this, there is limited data on the characteristics of patients who return unexpectedly to the ED after EDOU discharge. METHODS: We identified the charts of all patients who were admitted to the EDOU of an academic medical center between January 2018-June 2020 and had a return to the ED within 14 days of discharge from the EDOU. Patients were excluded if they were admitted to the hospital from the EDOU, left against medical advice, or died in the EDOU. We manually extracted selected demographic factors, comorbidities, and healthcare utilization data from the charts. Physician reviewers identified return visits thought to be related to the index visit or potentially avoidable. RESULTS: During the study period, there were 176,471 ED visits, 4,179 admissions to the EDOU, and 333 return visits to the ED within 14 days from discharge from the EDOU, representing 9.4% of all patients discharged from the EDOU. We identified a higher rate of return for patients treated for asthma and lower rates of return for patients treated for chest pain or syncope than the overall return rate. Physician reviewers determined that 64.6% of unplanned returns were related to the index visit, and 4.5% were potentially avoidable. Of potentially avoidable visits, 53.3% occurred within 48 hours of discharge, supporting the use of this period as a potential quality metric. While there was no significant difference in the percentage of related return visits between males and females, there was a higher rate of potentially avoidable visits for male patients. CONCLUSION: This study adds to the limited body of literature on EDOU returns, finding an overall return rate of under 10%, with about two-thirds of returns determined to be related to the index visit and <5% considered to be potentially avoidable.

Sex and race visual representation in emergency medicine textbooks and the hidden curriculum.

Introduction: In addition to formal training, informal training often occurs through a hidden curriculum. As the hidden curriculum shapes the knowledge and values held by learners, we must consider its role in implicit bias. One example is through the selection of images used in formal instruction. This study aimed to examine the representation of sex and race among images in two textbooks in emergency medicine (EM). Methods: We performed a cross-sectional study of the sex and race representation of figures in Rosen's Emergency Medicine: Concepts and Clinical Practice 9th Edition and Tintinalli's Emergency Medicine: A Comprehensive Study Guide 9th Edition. Two reviewers screened all images for inclusion, with disagreements resolved by a third reviewer. Images were excluded if they did not include visualized skin. Two reviewers independently reviewed each image and assessed the sex, race, and roles in the image. A third reviewer resolved any disagreements. Results: A total of 959 images (Rosen's n = 377; Tintinalli's n = 582) met inclusion criteria. Race was estimated in 877 cases (91.3%). Of those, White individuals comprised 77.6% (95% confidence interval [CI] 75.0%-80.2%). Sex was estimated in 362 cases (37.7%). Of those images, males comprised 70.2% (95% CI 65.4%-74.9%), and females comprised 29.8% (95% CI 25.1%-34.6%). Conclusion: There is a male sex and White race predominance in visual representation among two EM textbooks. We propose a call to action for the mindful selection of images in formal education to represent diversity, equity, and inclusion and close the gap between the formal and hidden curriculum.

Quintupling Inhaled Glucocorticoids to Prevent Childhood Asthma Exacerbations.

BACKGROUND: Asthma exacerbations occur frequently despite the regular use of asthma-controller therapies, such as inhaled glucocorticoids. Clinicians commonly increase the doses of inhaled glucocorticoids at early signs of loss of asthma control. However, data on the safety and efficacy of this strategy in children are limited. METHODS: We studied 254 children, 5 to 11 years of age, who had mild-to-moderate persistent asthma and had had at least one asthma exacerbation treated with systemic glucocorticoids in the previous year. Children were treated for 48 weeks with maintenance low-dose inhaled glucocorticoids (fluticasone propionate at a dose of 44 µg per inhalation, two inhalations twice daily) and were randomly assigned to either continue the same dose (low-dose group) or use a quintupled dose (high-dose group; fluticasone at a dose of 220 µg per inhalation, two inhalations twice daily) for 7 days at the early signs of loss of asthma control ("yellow zone"). Treatment was provided in a double-blind fashion. The primary outcome was the rate of severe asthma exacerbations treated with systemic glucocorticoids. RESULTS: The rate of severe asthma exacerbations treated with systemic glucocorticoids did not differ significantly between groups (0.48 exacerbations per year in the high-dose group and 0.37 exacerbations per year in the low-dose group; relative rate, 1.3; 95% confidence interval, 0.8 to 2.1; P=0.30). The time to the first exacerbation, the rate of treatment failure, symptom scores, and albuterol use during yellow-zone episodes did not differ significantly between groups. The total glucocorticoid exposure was 16% higher in the high-dose group than in the low-dose group. The difference in linear growth between the high-dose group and the low-dose group was -0.23 cm per year (P=0.06). CONCLUSIONS: In children with mild-to-moderate persistent asthma treated with daily inhaled glucocorticoids, quintupling the dose at the early signs of loss of asthma control did not reduce the rate of severe asthma exacerbations or improve other asthma outcomes and may be associated with diminished linear growth.

Individualized therapy for persistent asthma in young children.

BACKGROUND: Phenotypic presentations in young children with asthma are varied and might contribute to differential responses to asthma controller medications. METHODS: The Individualized Therapy for Asthma in Toddlers study was a multicenter, randomized, double-blind, double-dummy clinical trial in children aged 12 to 59 months (n = 300) with asthma necessitating treatment with daily controller (Step 2) therapy. Participants completed a 2- to 8-week run-in period followed by 3 crossover periods with daily inhaled corticosteroids (ICSs), daily leukotriene receptor antagonists, and as-needed ICS treatment coadministered with albuterol. The primary outcome was differential response to asthma medication based on a composite measure of asthma control. The primary analysis involved 2 stages: determination of differential response and assessment of whether 3 prespecified features (aeroallergen sensitization, previous exacerbations, and sex) predicted a differential response. RESULTS: Seventy-four percent (170/230) of children with analyzable data had a differential response to the 3 treatment strategies. Within differential responders, the probability of best response was highest for a daily ICS and was predicted by aeroallergen sensitization but not exacerbation history or sex. The probability of best response to daily ICS was further increased in children with both aeroallergen sensitization and blood eosinophil counts of 300/µL or greater. In these children daily ICS use was associated with more asthma control days and fewer exacerbations compared with the other treatments. CONCLUSIONS: In young children with asthma necessitating Step 2 treatment, phenotyping with aeroallergen sensitization and blood eosinophil counts is useful for guiding treatment selection and identifies children with a high exacerbation probability for whom treatment with a daily ICS is beneficial despite possible risks of growth suppression.

Acetaminophen versus Ibuprofen in Young Children with Mild Persistent Asthma.

BACKGROUND: Studies have suggested an association between frequent acetaminophen use and asthma-related complications among children, leading some physicians to recommend that acetaminophen be avoided in children with asthma; however, appropriately designed trials evaluating this association in children are lacking. METHODS: In a multicenter, prospective, randomized, double-blind, parallel-group trial, we enrolled 300 children (age range, 12 to 59 months) with mild persistent asthma and assigned them to receive either acetaminophen or ibuprofen when needed for the alleviation of fever or pain over the course of 48 weeks. The primary outcome was the number of asthma exacerbations that led to treatment with systemic glucocorticoids. Children in both groups received standardized asthma-controller therapies that were used in a simultaneous, factorially linked trial. RESULTS: Participants received a median of 5.5 doses (interquartile range, 1.0 to 15.0) of trial medication; there was no significant between-group difference in the median number of doses received (P=0.47). The number of asthma exacerbations did not differ significantly between the two groups, with a mean of 0.81 per participant with acetaminophen and 0.87 per participant with ibuprofen over 46 weeks of follow-up (relative rate of asthma exacerbations in the acetaminophen group vs. the ibuprofen group, 0.94; 95% confidence interval, 0.69 to 1.28; P=0.67). In the acetaminophen group, 49% of participants had at least one asthma exacerbation and 21% had at least two, as compared with 47% and 24%, respectively, in the ibuprofen group. Similarly, no significant differences were detected between acetaminophen and ibuprofen with respect to the percentage of asthma-control days (85.8% and 86.8%, respectively; P=0.50), use of an albuterol rescue inhaler (2.8 and 3.0 inhalations per week, respectively; P=0.69), unscheduled health care utilization for asthma (0.75 and 0.76 episodes per participant, respectively; P=0.94), or adverse events. CONCLUSIONS: Among young children with mild persistent asthma, as-needed use of acetaminophen was not shown to be associated with a higher incidence of asthma exacerbations or worse asthma control than was as-needed use of ibuprofen.

Defining 'reasonable medical certainty' in court: What does it mean to medical experts in child abuse cases?

Physicians and others who provide expert testimony in court cases involving alleged child abuse may be instructed to state their conclusions within a 'reasonable medical certainty' (RMC). However, neither judges nor jurors knows what degree of probability constitutes RMC for a given expert, nor whether different experts use different standards to formulate their opinions. We sought to better understand how experts define RMC in the context of court cases. An email survey was sent to members of six list-serves, representing four specialties, whose members testify in child abuse cases. Respondents were asked to define how RMC corresponded to (1) the numerical probability that abuse occurred, (2) the ordinal probability, and (3) how their determinations relate to common legal standards ('preponderance of the evidence', 'clear and convincing', and 'beyond a reasonable doubt'). Participants were also asked how comfortable they were in defining RMC; whether their definition changed according to the charges or type of proceeding; and how they would apply RMC to several hypothetical cases. The 294 list-serve participants who responded included child abuse pediatricians (46%), forensic pathologists (21%), pediatric neurosurgeons (15%), pediatric ophthalmologists (12%), and others (6%). Though 95% of respondents had testified in court, only 45% had received training in the definition of RMC. Only 37% were comfortable defining RMC. Although many responses were highly clustered and paired comparisons showed that 95% of participants' responses were internally consistent, there was variability in respondents' definitions of RMC. There is some variability in how child abuse expert witnesses define and use the term RMC; we provide suggestions about how to more accurately and transparently define RMC to ensure justice in these cases.

Early Administration of Azithromycin and Prevention of Severe Lower Respiratory Tract Illnesses in Preschool Children With a History of Such Illnesses: A Randomized Clinical Trial.

IMPORTANCE: Many preschool children develop recurrent, severe episodes of lower respiratory tract illness (LRTI). Although viral infections are often present, bacteria may also contribute to illness pathogenesis. Strategies that effectively attenuate such episodes are needed. OBJECTIVE: To evaluate if early administration of azithromycin, started prior to the onset of severe LRTI symptoms, in preschool children with recurrent severe LRTIs can prevent the progression of these episodes. DESIGN, SETTING, AND PARTICIPANTS: A randomized, double-blind, placebo-controlled, parallel-group trial conducted across 9 academic US medical centers in the National Heart, Lung, and Blood Institute's AsthmaNet network, with enrollment starting in April 2011 and follow-up complete by December 2014. Participants were 607 children aged 12 through 71 months with histories of recurrent, severe LRTIs and minimal day-to-day impairment. INTERVENTION: Participants were randomly assigned to receive azithromycin (12 mg/kg/d for 5 days; n = 307) or matching placebo (n = 300), started early during each predefined RTI (child's signs or symptoms prior to development of LRTI), based on individualized action plans, over a 12- through 18-month period. MAIN OUTCOMES AND MEASURES: The primary outcome measure was the number of RTIs not progressing to a severe LRTI, measured at the level of the RTI, that would in clinical practice trigger the prescription of oral corticosteroids. Presence of azithromycin-resistant organisms in oropharyngeal samples, along with adverse events, were among the secondary outcome measures. RESULTS: A total of 937 treated RTIs (azithromycin group, 473; placebo group, 464) were experienced by 443 children (azithromycin group, 223; placebo group, 220), including 92 severe LRTIs (azithromycin group, 35; placebo group, 57). Azithromycin significantly reduced the risk of progressing to severe LRTI relative to placebo (hazard ratio, 0.64 [95% CI, 0.41-0.98], P = .04; absolute risk for first RTI: 0.05 for azithromycin, 0.08 for placebo; risk difference, 0.03 [95% CI, 0.00-0.06]). Induction of azithromycin-resistant organisms and adverse events were infrequently observed. CONCLUSIONS AND RELEVANCE: Among young children with histories of recurrent severe LRTIs, the use of azithromycin early during an apparent RTI compared with placebo reduced the likelihood of severe LRTI. More information is needed on the development of antibiotic-resistant pathogens with this strategy. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01272635.

An assessment of variables affecting transition readiness in pediatric rheumatology patients.

BACKGROUND: We sought to identify which adolescent patient characteristics might lead to subjective reported independence in accessing medical care when patients transition from pediatric to adult medicine. METHODS: Pediatric and adult rheumatologists were asked which pediatric patient characteristics they believed would improve transition to adult medical care. Based on these responses, a questionnaire was created and administered to 76 teenage/young adult patients in a pediatric rheumatology clinic. The first set of questions included demographic, disease features, and life skills questions. The second set of questions pertained to self-reported independence in managing medical care. Data was analyzed to see if there were any significant associations between an individual's response to demographic, disease feature, or life skills questions and the independence outcome questions. RESULTS: In our study, older age correlated with self-reported independence in almost all questions asked regarding accessing medical care. Other patient characteristics that were associated with increased self-perceived autonomy included having a younger parent, having a family member with a similar disease, longer disease duration, having a comorbid non-rheumatic diagnosis, and having had a summer job. CONCLUSIONS: The patient characteristics that we found associated with self-reported independence in obtaining medical care should be considered when determining which patients might be more likely to make a successful transition.

Markers of Differential Response to Inhaled Corticosteroid Treatment Among Children with Mild Persistent Asthma.

BACKGROUND: Inhaled corticosteroids are recommended as first-line therapy for children with mild persistent asthma; however, specific patient characteristics may modify the treatment response. OBJECTIVE: Identify demographic, clinical, and atopic characteristics that may modify the inhaled corticosteroid treatment response among children enrolled in the Treating Children to Prevent Exacerbations of Asthma trial. METHODS: Children aged 6 to 18 years with mild persistent asthma were randomized to 44 weeks of combined, daily, rescue, or placebo treatment. Daily treatment consisted of 40 µg of beclomethasone twice daily. Rescue treatment consisted of 40 µg of beclomethasone accompanying each symptom-driven albuterol actuation. Combined treatment consisted of both. Outcomes included time to first exacerbation and proportion of asthma control days. Fourteen baseline characteristics were selected for interaction testing on the basis of their clinical relevance. RESULTS: Two hundred eighty-eight children were randomized. Seventy-five percent were white, and 55% were male. As measured by time to first exacerbation, 4 characteristics identified children who received greater benefit from treatment: non-Hispanic ethnicity, positive aeroallergen skin test result, serum immunoglobulin E level of 350 K/µL or more, and history of oral corticosteroid use in the year before enrollment. As measured by asthma control days, 4 characteristics identified children who received greater benefit from treatment: male sex, positive aeroallergen skin test result, serum immunoglobulin E level of 350 K/µL or more, and incomplete run-in asthma control. CONCLUSIONS: Children with mild persistent asthma who have markers of atopic asthma or who have greater asthma burden may obtain greater benefit from beclomethasone therapy. Additional study is needed to confirm whether these markers can guide individualized therapy.

Daily or intermittent budesonide in preschool children with recurrent wheezing.

BACKGROUND: Daily inhaled glucocorticoids are recommended for young children at risk for asthma exacerbations, as indicated by a positive value on the modified asthma predictive index (API) and an exacerbation in the preceding year, but concern remains about daily adherence and effects on growth. We compared daily therapy with intermittent therapy. METHODS: We studied 278 children between the ages of 12 and 53 months who had positive values on the modified API, recurrent wheezing episodes, and at least one exacerbation in the previous year but a low degree of impairment. Children were randomly assigned to receive a budesonide inhalation suspension for 1 year as either an intermittent high-dose regimen (1 mg twice daily for 7 days, starting early during a predefined respiratory tract illness) or a daily low-dose regimen (0.5 mg nightly) with corresponding placebos. The primary outcome was the frequency of exacerbations requiring oral glucocorticoid therapy. RESULTS: The daily regimen of budesonide did not differ significantly from the intermittent regimen with respect to the frequency of exacerbations, with a rate per patient-year for the daily regimen of 0.97 (95% confidence interval [CI], 0.76 to 1.22) versus a rate of 0.95 (95% CI, 0.75 to 1.20) for the intermittent regimen (relative rate in the intermittent-regimen group, 0.99; 95% CI, 0.71 to 1.35; P=0.60). There were also no significant between-group differences in several other measures of asthma severity, including the time to the first exacerbation, or adverse events. The mean exposure to budesonide was 104 mg less with the intermittent regimen than with the daily regimen. CONCLUSIONS: A daily low-dose regimen of budesonide was not superior to an intermittent high-dose regimen in reducing asthma exacerbations. Daily administration led to greater exposure to the drug at 1 year. (Funded by the National Heart, Lung, and Blood Institute and others; MIST ClinicalTrials.gov number, NCT00675584.).

Use of beclomethasone dipropionate as rescue treatment for children with mild persistent asthma (TREXA): a randomised, double-blind, placebo-controlled trial.

BACKGROUND: Daily inhaled corticosteroids are an effective treatment for mild persistent asthma, but some children have exacerbations even with good day-to-day control, and many discontinue treatment after becoming asymptomatic. We assessed the effectiveness of an inhaled corticosteroid (beclomethasone dipropionate) used as rescue treatment. METHODS: In this 44-week, randomised, double-blind, placebo-controlled trial we enrolled children and adolescents with mild persistent asthma aged 5-18 years from five clinical centres in the USA. A computer-generated randomisation sequence, stratified by clinical centre and age group, was used to randomly assign participants to one of four treatment groups: twice daily beclomethasone with beclomethasone plus albuterol as rescue (combined group); twice daily beclomethasone with placebo plus albuterol as rescue (daily beclomethasone group); twice daily placebo with beclomethasone plus albuterol as rescue (rescue beclomethasone group); and twice daily placebo with placebo plus albuterol as rescue (placebo group). Twice daily beclomethasone treatment was one puff of beclomethasone (40 µg per puff) or placebo given in the morning and evening. Rescue beclomethasone treatment was two puffs of beclomethasone or placebo for each two puffs of albuterol (180 µg) needed for symptom relief. The primary outcome was time to first exacerbation that required oral corticosteroids. A secondary outcome measured linear growth. Analysis was by intention to treat. This study is registered with clinicaltrials.gov, number NCT00394329. RESULTS: 843 children and adolescents were enrolled into this trial, of whom 288 were assigned to one of four treatment groups; combined (n=71), daily beclomethasone (n=72), rescue beclomethasone (n=71), and placebo (n=74)-555 individuals were excluded during the run-in, according to predefined criteria. Compared with the placebo group (49%, 95% CI 37-61), the frequency of exacerbations was lower in the daily (28%, 18-40, p=0·03), combined (31%, 21-43, p=0·07), and rescue (35%, 24-47, p=0·07) groups. Frequency of treatment failure was 23% (95% CI 14-43) in the placebo group, compared with 5·6% (1·6-14) in the combined (p=0·012), 2·8% (0-10) in the daily (p=0·009), and 8·5% (2-15) in the rescue (p=0·024) groups. Compared with the placebo group, linear growth was 1·1 cm (SD 0·3) less in the combined and daily arms (p<0·0001), but not the rescue group (p=0·26). Only two individuals had severe adverse events; one in the daily beclomethasone group had viral meningitis and one in the combined group had bronchitis. INTERPRETATION: Children with mild persistent asthma should not be treated with rescue albuterol alone and the most effective treatment to prevent exacerbations is daily inhaled corticosteroids. Inhaled corticosteroids as rescue medication with albuterol might be an effective step-down strategy for children with well controlled, mild asthma because it is more effective at reducing exacerbations than is use of rescue albuterol alone. Use of daily inhaled corticosteroid treatment and related side-effects such as growth impairment can therefore be avoided. FUNDING: National Heart, Lung and Blood Institute.

Outcome assessment of blunt trauma patients who are undertriaged.

BACKGROUND: We investigated the outcomes of injured patients who were undertriaged and compared them with those meeting full trauma team activation (TTA) criteria. METHODS: Blunt trauma patients (July 2002-January 2008) meeting full TTA criteria and had a partial TTA were in the undertriage group (UTG). Data was collected on demographics, injury severity, OR delays, resource utilization, and outcomes. Excluded: penetrating trauma, transfers, burns, age <18 years. STATISTICS: Chi square, P < .05, mean +/- SD. RESULTS: One thousand four hundred and twenty-four patients with 318 (22.3%) in the UTG and 1,106 in the correctly triaged group (CTG). The CTG was 70.4% male (vs 67.1%; P = .26), 41.5 +/- 19.8 years old (vs 45.8 +/- 20.5; P < .01), and had an injury severity score (ISS) of 24.7 (vs 17.0; P < .0001). The CTG was more likely to require ED intubation (34.9% vs 8.2%; P < .0001), ICU admission (49.0% vs 37.1%; P < .0001), longer ICU/hospital LOS, and more ventilator days (P < .0001) with no differences in OR delays. The UTG had a lower mortality (6.0% vs 16.7%; P < .0001) and were discharged home more often (65.3% vs 52.2%; P = .02). CONCLUSION: The UTG had a lower ISS and improved outcomes compared to the CTG with no differences in OR delays. Despite inherent challenges in TTA protocols, patients who were undertriaged at our institution appear to have satisfactory outcomes.

Step-up therapy for children with uncontrolled asthma receiving inhaled corticosteroids.

BACKGROUND: For children who have uncontrolled asthma despite the use of low-dose inhaled corticosteroids (ICS), evidence to guide step-up therapy is lacking. METHODS: We randomly assigned 182 children (6 to 17 years of age), who had uncontrolled asthma while receiving 100 microg of fluticasone twice daily, to receive each of three blinded step-up therapies in random order for 16 weeks: 250 microg of fluticasone twice daily (ICS step-up), 100 microg of fluticasone plus 50 microg of a long-acting beta-agonist twice daily (LABA step-up), or 100 microg of fluticasone twice daily plus 5 or 10 mg of a leukotriene-receptor antagonist daily (LTRA step-up). We used a triple-crossover design and a composite of three outcomes (exacerbations, asthma-control days, and the forced expiratory volume in 1 second) to determine whether the frequency of a differential response to the step-up regimens was more than 25%. RESULTS: A differential response occurred in 161 of 165 patients who were evaluated (P<0.001). The response to LABA step-up therapy was most likely to be the best response, as compared with responses to LTRA step-up (relative probability, 1.6; 95% confidence interval [CI], 1.1 to 2.3; P=0.004) and ICS step-up (relative probability, 1.7; 95% CI, 1.2 to 2.4; P=0.002). Higher scores on the Asthma Control Test before randomization (indicating better control at baseline) predicted a better response to LABA step-up (P=0.009). White race predicted a better response to LABA step-up, whereas black patients were least likely to have a best response to LTRA step-up (P=0.005). CONCLUSIONS: Nearly all the children had a differential response to each step-up therapy. LABA step-up was significantly more likely to provide the best response than either ICS or LTRA step-up. However, many children had a best response to ICS or LTRA step-up therapy, highlighting the need to regularly monitor and appropriately adjust each child's asthma therapy.

Librarian instruction-delivery modality preferences for professional continuing education.

OBJECTIVES: Attending professional continuing education (CE) is an important component of librarianship. This research study identified librarians' preferences in delivery modalities of instruction for professional CE. The study also identified influential factors associated with attending CE classes. METHODS: Five instruction-delivery modalities and six influential factors were identified for inclusion in an online survey. The survey completed by members of the American Library Association (ALA), Special Libraries Association (SLA), and Medical Library Association (MLA) provided the data for analysis of librarian preferences and influential factors. RESULTS: The majority of respondents were MLA members, followed by ALA and SLA members. Librarians from all three library associations preferred the face-to-face instructional modality. The most influential factor associated with the decision to attend a professional CE class was cost. CONCLUSIONS: All five instruction-delivery modalities present useful structures for imparting professional CE. As librarians' experience with different modalities increases and as technology improves, preferences in instruction delivery may shift. But at present, face-to-face remains the most preferred modality. Based on the results of this study, cost was the most influential factor associated with attending a CE class. This may change as additional influential factors are identified and analyzed in future studies.
