A descriptive study of screening and navigation on health-related social needs in a safety-net hospital emergency department.

BACKGROUND: Health-related social needs (HRSN) have been associated with worse clinical outcomes, increased Emergency Department (ED) utilization and higher healthcare costs. The ED is uniquely positioned to bring HRSN screening to the bedside and develop effective interventions. We evaluated whether navigation services for high-risk patients led to the resolution of HRSN. METHODS: Navigators screened a convenience sample of patients for HRSN with the Accountable Health Communities Screening Tool from October 2019 to January 2022. Patients with HRSN were considered high-risk if they had at least two ED visits in the previous 12 months. Patients who were high-risk were eligible for navigation including community referrals and one-on-one close follow-up. The HRSN status (resolved, in-progress, unable to resolve) was queried from the Centers for Medicare and Medicaid database. The state hospital association provided data on ED visits and inpatient hospitalizations within 6 months of the screening visit. RESULTS: Of 185,470 ED visits, HRSN screening occurred in 4050 (2%). HRSN were self-reported in 48% (1944) of patient visits, with 71% of these (1379) considered high-risk. 15% of high-risk patients with HRSN opted out of navigation. Food insecurity was the most identified HRSN (35%) followed by housing instability (26%), transportation needs (24%) and utility assistance (15%). Food insecurity was the most resolved HRSN (39%, in-progress 32%) followed by utility assistance (37%, in-progress 26%), transportation needs (35%, in-progress 35%) and housing instability (28%, in-progress 36%). High-risk visits in which the patient or guardian accepted navigation were less likely to be associated with an ED visit within 6 months of the screening visit (51%) compared to high-risk patients in which the patient or guardian opted out of navigation (61%, p < 0.001), but there was no difference in inpatient hospitalizations (p = 0.427). CONCLUSIONS: During the study period, one-third of HRSN were successfully resolved with another one-third in-progress. Navigation in high-risk patients was associated with fewer subsequent ED visits.

Screening for health-related social needs in the emergency department: Adaptability and fidelity during the COVID-19 pandemic.

BACKGROUND AND OBJECTIVES: We sought to evaluate a screening and referral program for health-related social needs (HRSN) in our ED. Our goals were to (1) quantify successful screenings prior to and during the initial peak of the pandemic, and (2) describe the HRSNs identified. METHODS: We performed an observational analysis of ED-based screening for HRSN in Medicare and Medicaid patients at our large urban safety-net hospital. Screening was performed by patient navigators utilizing the ten question, validated Accountable Health Communities (AHC) Screening Tool, which screens for food insecurity, housing instability, transportation needs and utility assistance and interpersonal safety. Patients who screened positive for HRSN were provided with handouts listing community resources. For patients with two or more self-reported ED visits in the last 12 months and any identified HRSN, ongoing navigation after discharge was provided utilizing community resource referrals. During the pre-pandemic period from November 1, 2019 - January 31, 2020, screening occurred in-person. Screening during the pandemic from March 1, 2020 - May 31, 2020 occurred remotely via telephone. Descriptive statistics including frequency rates and percentages were calculated. Successful screening was defined as completing the screening survey with a navigator and being triaged to either no assistance, resource handouts, or navigation services. RESULTS: Among the adult and pediatric patients screened for HRSN, 158 (16%) qualified for community resource handouts and 440 (44.4%) qualified for patient navigator services. The proportion of patients receiving both resources and care navigation remained similar in the pre- and post-periods of the study, at 227 (45%) and 213 (43.9%) respectively. However, the proportion of ED patients with a HRSN need doubled from 56 (11.1%) in the pre-period to 102 (21%) in the post-period. Food insecurity was the most identified HRSN in both the pre-pandemic period (27.3%) and during the pandemic (35.8%). CONCLUSION: We found that remote HRSN screening for ED patients during the COVID-19 pandemic resulted in similar proportions of successfully completed screenings compared to pre-pandemic efforts. This demonstrates the feasibility of utilizing alternative methods of screening and referral to community resources from the ED, which could facilitate this type of intervention in other EDs. During the pandemic HRSN increased, likely reflecting the economic impact of the pandemic.

Evaluation of a Novel Point-of-Care Ultrasound Curriculum for First-Year Pediatric Residents.

OBJECTIVE: The aim of the study is to evaluate a novel point-of-care ultrasound (POCUS) educational curriculum for pediatric residents. METHODS: The cohort study in graduate medical education was completed from January 2017 to March 2019. Postgraduate year 1 (PGY1) pediatric residents attended the educational curriculum that consisted of 3 half-day sessions over a 3-month period. Each session consisted of a lecture (introduction, extended focused assessment with sonography for trauma, soft tissue/musculoskeletal, cardiac, and resuscitative applications) followed by supervised hands-on scanning sessions. Group ratio was 3 learners to 1 machine/expert instructor. Main outcome measures included pre- and post-written test scores, as well as objective structured clinical examination (OSCE) scores. RESULTS: Forty-nine PGY1 residents (78% women) completed the curriculum. The mean (SD) pretest score was 68% (8.5), and the mean posttest score was 83% (8.3) with a difference of 15 (95% confidence interval, 12.5-17.6; P < 0.001). Mean (SD) focused assessment with sonography for trauma OSCE score after the curriculum was 88.7% (11.9). The number of PGY1 pediatric residents that were comfortable performing POCUS examinations increased from pretraining to posttraining for soft tissue/musculoskeletal (14%-61%, P < 0.001), extended focused assessment with sonography for trauma (24%-90%, P < 0.001), and cardiac (18%-86%, P < 0.001). All participants found the curriculum useful, and 42 of 49 (86%) stated the curriculum increased their ability to acquire and interpret images. CONCLUSIONS: Postgraduate year 1 pediatric residents learned the basics of POCUS through 3 brief educational sessions. The increase in posttest scores demonstrated improved POCUS knowledge, and the high OSCE score demonstrated their ability to acquire ultrasound images. Point-of-care ultrasound guidelines are needed for pediatric residency programs.

Adverse Events During a Randomized Trial of Ketamine Versus Co-Administration of Ketamine and Propofol for Procedural Sedation in a Pediatric Emergency Department.

BACKGROUND: The co-administration of ketamine and propofol (CoKP) is thought to maximize the beneficial profile of each medication, while minimizing the respective adverse effects of each medication. OBJECTIVE: Our objective was to compare adverse events between ketamine monotherapy (KM) and CoKP for procedural sedation and analgesia (PSA) in a pediatric emergency department (ED). METHODS: This was a prospective, randomized, single-blinded, controlled trial of KM vs. CoKP in patients between 3 and 21 years of age. The attending physician administered either ketamine 1 mg/kg i.v. or ketamine 0.5 mg/kg and propofol 0.5 mg/kg i.v. The physician could administer up to three additional doses of ketamine (0.5 mg/kg/dose) or ketamine/propofol (0.25 mg/kg/dose of each). Adverse events (e.g., respiratory events, cardiovascular events, unpleasant emergence reactions) were recorded. Secondary outcomes included efficacy, recovery time, and satisfaction scores. RESULTS: Ninety-six patients were randomized to KM and 87 patients were randomized to CoKP. There was no difference in adverse events or type of adverse event, except nausea was more common in the KM group. Efficacy of PSA was higher in the KM group (99%) compared to the CoKP group (90%). Median recovery time was the same. Satisfaction scores by providers, including nurses, were higher for KM, although parents were equally satisfied with both sedation regimens. CONCLUSIONS: We found no significant differences in adverse events between the KM and CoKP groups. While CoKP is a reasonable choice for pediatric PSA, our study did not demonstrate an advantage of this combination over KM.

The 2012 PEMpix photograph competition award winner: making a case for pringles-flavored carrots.

This is a case report of a 14-year-old boy with autism who presented with photophobia. Physical examination was significant for bilateral corneal ulcers. Differential diagnosis of this chief complaint and the management of the suspected condition are discussed. This case was presented at the Section of Emergency Medicine Meeting at the National Conference and Exhibition of the American Academy of Pediatrics in 2012 and was awarded first place in the PEMpix photograph competition.

Improving Management of Suspected Chlamydia and Gonorrhea in Adolescents with a Rapid Diagnostic Test.

We aimed to determined the impact of an intervention using rapid chlamydia (CT)/gonorrhea (GC) testing on reducing unnecessary antibiotic use, undertreatment of CT and/or GC, and length of stay (LOS) in an urban safety-net pediatric emergency department. Methods: Before 2020, we tested for CT/GC using a batched nucleic acid amplification test, with results available the following day. Starting in January 2020, we implemented rapid nucleic acid amplification test. Our primary outcome variables were undertreatment and overtreatment. We defined undertreatment as GC and/or CT-positive patients who did not receive appropriate treatment. We defined overtreatment as GC or CT-negative patients who received antibiotics. The balancing measure was the LOS. Results: There were 758 patients evaluated in the preimplementation period (2019), 612 in the implementation period (2020), and 626 in the postimplementation period (2021). Postimplementation, overtreatment decreased from 18.4% to 8.1%. Undertreatment did not differ by period but was less common among those tested with rapid versus standard testing (12.7% versus 9.9%, P = 0.05). Median LOS increased from 166 minutes (preimplementation) to 187 minutes (implementation) and 202 minutes (postimplementation; P < 0.001). Conclusions: Rapid CT/GC testing reduced unnecessary antibiotic use but increased LOS due to patients waiting for the test results before being discharged. Given the rapid increases in CT/GC rates and antimicrobial resistance, health systems should consider implementing rapid testing to appropriately direct antimicrobials to patients most likely to benefit.

Point-of-Care Ultrasound Use by EMS Providers in Out-of-Hospital Cardiac Arrest.

AIM: Paramedics received training in point-of-care ultrasound (POCUS) to assess for cardiac contractility during management of medical out-of-hospital cardiac arrest (OHCA). The primary outcome was the percentage of adequate POCUS video acquisition and accurate video interpretation during OHCA resuscitations. Secondary outcomes included POCUS impact on patient management and resuscitation protocol adherence. METHODS: A prospective, observational cohort study of paramedics was performed following a four-hour training session, which included a didactic lecture and hands-on POCUS instruction. The Prehospital Echocardiogram in Cardiac Arrest (PECA) protocol was developed and integrated into the resuscitation algorithm for medical non-shockable OHCA. The ultrasound (US) images were reviewed by a single POCUS expert investigator to determine the adequacy of the POCUS video acquisition and accuracy of the video interpretation. Change in patient management and resuscitation protocol adherence data, including end-tidal carbon dioxide (EtCO2) monitoring following advanced airway placement, adrenaline administration, and compression pauses under ten seconds, were queried from the prehospital electronic health record (EHR). RESULTS: Captured images were deemed adequate in 42/49 (85.7%) scans and paramedic interpretation of sonography was accurate in 43/49 (87.7%) scans. The POCUS results altered patient management in 14/49 (28.6%) cases. Paramedics adhered to EtCO2 monitoring in 36/36 (100.0%) patients with an advanced airway, adrenaline administration for 38/38 (100.0%) patients, and compression pauses under ten seconds for 36/38 (94.7%) patients. CONCLUSION: Paramedics were able to accurately obtain and interpret cardiac POCUS videos during medical OHCA while adhering to a resuscitation protocol. These findings suggest that POCUS can be effectively integrated into paramedic protocols for medical OHCA.

Little boy black and blue.

Tooth decay is common in US children, especially for children in low-income families. More than half of second-grade children have cavities. Therefore, root canal procedures are becoming more common in children. We report a case of a 2-year-old boy with a rare complication of a root canal procedure secondary to sodium hypochlorite toxicity. Sodium hypochlorite, a commonly used root canal irrigant, and its toxicity are reviewed.

Educational Benefits of Allowing Pediatrician Supervision of Emergency Medicine Residents.

BACKGROUND: According to the Accreditation Council for Graduate Medical Education emergency medicine (EM) program requirements, EM residents on EM rotations must be supervised by board-certified/board-prepared EM or pediatric EM (PEM) faculty. OBJECTIVE: We sought to understand the effect of allowing EM residents to be supervised by attending pediatricians while caring for pediatric urgent care patients. METHODS: The EM residents were permitted to staff pediatric urgent care patients with either an EM/PEM attending or an attending pediatrician from August 2017 to July 2018. Outcomes were assessed through resident focus groups, a mixed-methods survey of EM residents and EM/PEM/pediatrician attendings, and clinical outcomes, including length of stay, best evidence/clinical care guideline adherence, and 48-hour return visits requiring admission. Qualitative data were inductively coded using a phenomenological framework, with themes emerging from consensus discussion. RESULTS: Ninety percent of residents participated in 1 of 7 focus groups. Four key themes emerged from qualitative analysis of focus group transcripts: (1) pediatricians have unique skills that complement those of EM physicians; (2) EM resident education improved; (3) patients may get better care with dual staffing; and (4) other PEM department and urgent care team members may have benefited from the change. The survey response rate was 72%, and it did not uncover additional themes. Length of stay was shorter for patients supervised by attending pediatricians (114 versus 128 minutes, P < .001); there was no difference in best evidence/clinical care guideline adherence or 48-hour return visits requiring admission. CONCLUSIONS: Physicians' perceived education was improved by adding complementary perspectives without significant negative consequences for learners or patients.

Comparison of clinical characteristics and frequency of adverse outcomes in patients with Marfan syndrome diagnosed in adulthood versus childhood.

Patients with Marfan syndrome (MFS) continue to elude diagnosis until well into adulthood. The purpose of this study was to compare the clinical characteristics and outcomes of adult survivors with MFS diagnosed during adulthood (age, >or=18 years) with those of adult survivors with MFS diagnosed in childhood (<18 years). We conducted a retrospective review of 66 adult (age, >18 years) MFS patients seen at a combined pediatric and adult multidisciplinary MFS clinic from 2004 to 2006. Demographic, clinical, and cardiac variables were collected and a comparative analysis was performed between the two groups: patients diagnosed with MFS during childhood and patients diagnosed in adulthood. The primary outcome measures were the presence of aortic dissection and the need for urgent cardiovascular surgery. Despite a similar incidence of clinical characteristics, 39 of the 66 MFS patients were not diagnosed until adulthood. The overall incidence of major cardiac involvement was comparable between the two groups, although the patients diagnosed at a younger age were found to have a reduced need for aortic surgery (33% vs. 59%; P < 0.04) and fewer adverse cardiac outcomes (0% vs. 46%; P < 0.001). Moreover, the patients diagnosed with MFS in adulthood were more likely to require repeated surgical intervention for distal aortic disease (13% vs. 0%; P = 0.07). In conclusion, patients with MFS who remain undiagnosed until adulthood have well-established cardiovascular pathology frequently requiring surgical intervention. Due to this delay in diagnosis and management, they often suffer from a suboptimal clinical outcome. Our research demonstrates the importance of educating pediatric clinicians in early MFS diagnosis in hopes of improving the long-term outcome of all MFS patients.

The impact of parental primary language on communication in the neonatal intensive care unit.

OBJECTIVE: Language barriers contribute to suboptimal healthcare delivery. We sought to explore disparities in communication between English and Spanish-speaking parents and their neonatal intensive care unit (NICU) providers. STUDY DESIGN: We compared English-speaking versus Spanish-speaking parents' understanding of their infant's diagnosis through a structured interview. RESULTS: Spanish-speaking parents were four times (RR 4.0, 95% CI: 1.5, 11.0; p = 0.004) more likely to incorrectly identify their child's diagnosis than English-speaking parents. Spanish speakers also self-reported lower understanding of NICU interventions. Physicians provided updates to Spanish-speaking parents in their native language only 39% of the time. CONCLUSIONS: Spanish-speaking NICU parents more commonly misunderstood aspects of their child's care than did English-speaking parents. Providers' failed to communicate with Spanish-speaking families in their native language the majority of the time. Additional research is needed to assess the barriers to effective communication between NICU providers and Spanish-speaking parents.

A comparison of oral dexamethasone with oral prednisone in pediatric asthma exacerbations treated in the emergency department.

The aim of this study was to determine if 2 doses of oral dexamethasone are as effective as a 5-day course of oral prednisone in preventing relapse for pediatric asthma exacerbations. Patients presenting to the emergency department with an asthma exacerbation were randomized to receive 0.6 mg/kg of dexamethasone or 2 mg/kg of prednisone in a prospective, double-blind study. The primary outcome was relapse within 10 days, and the secondary outcome was vomiting in the emergency department. Eighty-nine patients completed the study: 38 in the prednisone group and 51 in the dexamethasone group. In all, 3 patients in the prednisone group (8%) and 8 patients in the dexamethasone group (16%) required an unscheduled follow-up visit (P = .27). In all, 7 patients in the prednisone group (18%) and 5 patients in the dexamethasone group (10%) had vomiting ( P = .24). No difference was found in the relapse rate or incidence of vomiting between patients given prednisone and dexamethasone for pediatric asthma exacerbations.

A Randomized Double Blind Trial of Needle-free Injected Lidocaine Versus Topical Anesthesia for Infant Lumbar Puncture.

OBJECTIVES: Lumbar punctures (LPs) are commonly performed in febrile infants to evaluate for meningitis, and local anesthesia increases the likelihood of LP success. Traditional methods of local anesthesia require injection that may be painful or topical application that is not effective immediately. Recent advances in needle-free jet injection may offer a rapid alternative to these modalities. We compared a needle-free jet-injection system (J-Tip) with 1% buffered lidocaine to topical anesthetic (TA) cream for local anesthesia in infant LPs. METHODS: This was a single-center randomized double-blind trial of J-Tip versus TA for infant LPs in an urban tertiary care children's hospital emergency department. A computer randomization model was used to allocate patients to either intervention. Patients aged 0 to 4 months were randomized to J-Tip syringe containing 1% lidocaine and a placebo TA cream or J-Tip syringe containing saline and TA. The primary outcome was the difference between the Neonatal Faces Coding Scale (NFCS) before the procedure and during LP needle insertion. Secondary outcomes included changes in heart rate (HR) and NFCS throughout the procedure, difficulty with LP, number of LP attempts, provider impression of pain control, additional use of lidocaine, skin changes at LP site, and LP success. RESULTS: We enrolled 66 subjects; 32 were randomized to J-Tip with lidocaine and 34 to EMLA. Six participants were excluded from the final analysis due to age greater than 4 months, and the remaining 58 were analyzed in their respective groups (32 J-Tip, 34 TA). There was no difference detected in NFCS between the two treatment groups before the procedure and during needle insertion for the LP (p = 0.58, p = 0.37). Neither HR nor NCFS differed among the groups throughout the procedure. Median perception of pain control by the provider and the need for additional lidocaine were comparable across groups. LPs performed with a J-Tip were twice as likely to be successful compared to those performed using TA (relative risk = 2.0; 95% confidence interval = 1.01-3.93; p = 0.04) with no difference in level of training or number of prior LPs performed by providers. CONCLUSIONS: In a randomized controlled trial of two modalities for local anesthesia in infant LPs, J-Tip was not superior to TA cream as measured by pain control or physiologic changes. Infant LPs performed with J-Tip were twice as likely to be successful.

Pediatric appendicitis: Is referral to a regional pediatric center necessary?

BACKGROUND: Acute appendicitis is the most common emergent surgical procedure performed among children in the United States, with an incidence exceeding 80,000 cases per year. Appendectomies are often performed by both pediatric surgeons and adult general/trauma and acute care (TACS) surgeons. We hypothesized that children undergoing appendectomy for acute appendicitis have equivalent outcomes whether a pediatric surgeon or a TACS surgeon performs the operation. METHODS: A retrospective chart review was performed for patients 6 to 18 years of age, who underwent appendectomy at either a regional children's hospital (Children's Hospital of Colorado [CHCO], n = 241) or an urban safety-net hospital (n = 347) between July 2010 and June 2015. The population of patients operated on at the urban safety-net hospital was further subdivided into those operated on by pediatric surgeons (Denver Health Medical Center [DHMC] pediatric surgeons, n = 68) and those operated on by adult TACS surgeons (DHMC TACS, n = 279). Baseline characteristics and operative outcomes were compared between these patient populations utilizing one-way analysis of variance and χ test for independence. RESULTS: When comparing the CHCO and DHMC TACS groups, there were no differences in the proportion of patients with perforated appendicitis, operative time, rate of operative complications, rate of postoperative infectious complications, or rate of 30-day readmission. Length of stay was significantly shorter for the DHMC TACS group than that for the CHCO group. CONCLUSIONS: Our data demonstrate that among children older than 5 years undergoing appendectomy, length of stay, risk of infectious complications, and risk of readmission do not differ regardless of whether they are operated on by pediatric surgeons or adult TACS surgeons, suggesting resources currently consumed by transferring children to hospitals with access to pediatric surgeons could be allocated elsewhere. LEVEL OF EVIDENCE: Therapeutic/Care management, level III.

Rapid Response Team Activations in Pediatric Surgical Patients.

Introduction The rapid response team (RRT) is a multidisciplinary team who evaluates hospitalized patients for concerns of nonemergent clinical deterioration. RRT evaluations are mandatory for children whose Pediatric Early Warning System (PEWS) score (assessment of child's behavior, cardiovascular and respiratory status) is ≥4. We aimed to determine if there were differences in characteristics of RRT calls between children who were admitted primarily to either medical or surgical services. We hypothesized that RRT activations would be called for less severely ill children with lower PEWS score on surgical services compared with children admitted to a medical service. Materials and Methods We performed a retrospective review of all children with RRT activations between January 2008 and April 2015 at a tertiary care pediatric hospital. We evaluated the characteristics of RRT calls and made comparisons between RRT calls made for children admitted primarily to medical or surgical services. Results A total of 2,991 RRT activations were called, and 324 (11%) involved surgical patients. Surgical patients were older than medical patients (median: 7 vs. 4 years; p < 0.001). RRT evaluations were called for lower PEWS score in surgical patients compared with medical (median: 3 vs. 4, p < 0.001). Surgical patients were more likely to remain on the inpatient ward following the RRT (51 vs. 39%, p < 0.001) and were less likely to require an advanced airway than medical patients (0.9 vs. 2.1%; p = 0.412). RRT evaluations did not differ between day and night shifts (52% day vs. 48% night; p = 0.17). All surgical patients and all but one medical patient survived the event; surgical patients were more likely to survive to hospital discharge (97 vs. 91%, p < 0.001) Conclusions RRT activations are rare events among pediatric surgical patients. When compared with medical patients, RRT evaluation is requested for surgical patients with a lower PEWS score and these children are less likely to require transfer to a higher level of care, suggesting that pediatric surgery team, families, and nursing staff may not be as comfortable with clinical deterioration.

Deficits in EMTALA Knowledge Among Pediatric Physicians.

OBJECTIVE: All US hospitals that participate in Medicare and Medicaid are regulated by the Emergency Medical Treatment and Active Labor Act (EMTALA). The law was enacted to prevent hospitals from turning away patients with emergency medical conditions. The law imposes specific obligations on hospitals and their physicians, and provides severe penalties for violations. The objective of this study was to evaluate hospital-based pediatric physicians' knowledge of these obligations and potential liabilities. METHODS: A questionnaire was submitted to the active medical staff and pediatric subspecialty residents at a tertiary care pediatric hospital. The questionnaire collected demographic information and posed 12 questions, based on well-established EMTALA principles, which addressed specific EMTALA obligations and liabilities. RESULTS: The questionnaire was returned by 123 of 332 (37%) potential participants. Twenty-four percent (n = 30) had never heard of EMTALA, 24% (n = 30) had only "heard of" the law, and 51% (n = 63) considered themselves "generally familiar" with EMTALA. No respondent correctly answered all 12 questions, and 13% (n = 16) answered all 12 questions incorrectly. The median score was 42%, with a range of 0% to 83% correct. Only 20% (n = 25) reported that they had ever received any EMTALA education. Prior EMTALA education was associated with a higher score (P = 0.001). Eighty percent (n = 98) expressed interest in attending a formal EMTALA education program. CONCLUSIONS: Physicians at this pediatric hospital were strikingly unaware of their EMTALA obligations and potential liabilities. A specific educational program regarding EMTALA should be provided to hospital-based pediatric physicians to improve compliance with the law and reduce potential liabilities.

Lack of utility of repeat monitoring of hemoglobin and hematocrit following blunt solid organ injury in children.

BACKGROUND: Current management protocols for children with blunt solid organ injury to the liver and spleen call for serial monitoring of the child's hemoglobin and hematocrit every 6, 12, or 24 hours, depending on the injury grade. We hypothesized that children who require emergent intervention in the form of laparotomy, angioembolization, or packed red blood cell (PRBC) transfusion because of bleeding from a solid organ injury will have changes in their vital signs that alert the clinician to the need for intervention, making scheduled laboratory evaluation unnecessary. METHODS: We performed a retrospective review of all children admitted to either of two pediatric trauma centers following blunt trauma with any grade liver or spleen injury from January 2009 to December 2013. Data evaluated include a need for intervention, indication for intervention, and timing of intervention. RESULTS: A total of 245 children were admitted with blunt liver or spleen injury. Six patients (2.5%) underwent emergent exploratory laparotomy for hypotension a median of 4 hours after injury (range, 2-4 hours), four of who required splenectomy. No child required laparotomy for delayed bleeding from a solid organ injury. One child (0.4%) underwent angioembolization for blunt splenic injury. Forty-one children (16.7%) received a PRBC transfusion during hospitalization, 32 of whom did not undergo laparotomy or angioembolization. Children who underwent an intervention had a lower nadir hematocrit (median, 22.9 vs. 32.8; p < 0.0001), longer time from injury to nadir hematocrit (median, 35.5 vs. 16 hours; p < 0.0001), and more total blood draws for hemoglobin and hematocrit monitoring (median, 20 vs. 5; p < 0.0001). CONCLUSION: Among children with blunt liver or spleen injury, a need for emergent intervention in the form of laparotomy or PRBC transfusion for hemorrhagic shock occurs within the first 24 hours of injury. Ongoing, scheduled monitoring of serum hemoglobin and hematocrit values may not be necessary. LEVEL OF EVIDENCE: Retrospective study with no negative criteria, prognostic study, level III.

When is it safe to forgo abdominal CT in blunt-injured children?

INTRODUCTION: CT is the standard modality to diagnose solid organ injury after blunt trauma; however, the associated radiation carries a risk of cancer. We hypothesized that there are patient-specific factors that can identify those children who require abdominal CT. METHODS: We reviewed all children admitted to 2 pediatric trauma centers after blunt trauma with liver or spleen injury from January 2009 to December 2013. The low-risk group was defined as a Glasgow Coma Scale (GCS) of 15 with normal pediatric age-adjusted shock index (heart rate/systolic blood pressure; SIPA) on presentation, and injury attributable to a single, nonmotorized, blunt force to the abdomen. The at-risk group did not meet these criteria. RESULTS: We identified 206 children with blunt liver or spleen injury, 101 of whom met the low-risk criteria. Among these 101 children who met the low-risk criteria, there were no deaths, no children required laparotomy, only 1 child required a packed red cell transfusion, and no children required discharge to a rehabilitation facility. CONCLUSION: Children who present to the emergency department after blunt abdominal trauma by a nonmotorized force with a normal GCS and SIPA are unlikely to have a solid organ injury that will require intervention.

Utility of anaerobic blood cultures in a pediatric emergency department.

OBJECTIVES: To determine the frequency with which clinically significant bacterial pathogens are isolated only from the anaerobic blood culture medium in children evaluated for bacteremia and to describe the clinical features associated with these positive cultures. METHODS: Retrospective review of all blood cultures received from the emergency department in the microbiology laboratory. Clinically significant pathogens were defined as microorganisms that rarely are considered to be contaminants or microorganisms that are recovered from multiple blood cultures or sites from the same individual. Charts of all patients with positive anaerobic cultures for clinically significant pathogens in the presence of negative aerobic cultures were reviewed. The setting was an urban tertiary care pediatric emergency department. RESULTS: 2675 paired blood cultures were performed between January 1, 1998 and December 31, 2000. Growth of a bacterial organism occurred in 595 of the paired samples. Two hundred seventy-eight were clinically significant pathogens. One hundred sixty-two (58.3%) were present in both the aerobic and anaerobic mediums, 85 (30.6%) were only in the aerobic medium, and 31 (11.2%) were only in the anaerobic medium. Most patients with growth only in the anaerobic medium had underlying conditions (ie, central venous line, immunocompromised, congenital heart disease, liver disease, age < 3 months). No obligate anaerobic organisms were detected. CONCLUSIONS: In a pediatric emergency department setting, almost all pathogenic bacteria were isolated from aerobic culture mediums in otherwise healthy children. The yield of routinely performed anaerobic blood cultures is low. In previously healthy children, it may be optimal to inoculate the entire blood volume obtained into the aerobic medium.
