Critical procedure performance in pediatric patients: Results from a national emergency medicine group.

STUDY OBJECTIVE: We sought to examine the frequency of pediatric critical procedures performed in a national group of emergency physicians. METHODS: We performed a retrospective analysis of an administrative billing and coding dataset for procedural performance documentation verification from 2014 to 2018. We describe and compare incident rates of pediatric (age <18 years) patient critical procedure performance by emergency physicians in general emergency departments (EDs), pediatric EDs, and freestanding ED/urgent care centers. Critical procedures were endotracheal intubation, electrical cardioversion, central venous placement, intraosseous access, and chest tube insertion. RESULTS: Among 2290 emergency physicians working in 186 EDs (1844 working in 129 general EDs, 125 in 8 pediatric EDs, and 321 in 49 freestanding EDs/urgent cares), a total of 2233 pediatric critical procedures were performed during the study period. Many physicians at general EDs and freestanding EDs/urgent cares performed zero pediatric procedures per year (53.9% and 89% respectively). Per 1000 ED visits seen (All patient ages), physicians working in general EDs performed fewer pediatric critical procedures than physicians in pediatric EDs (0.12/1000 visits vs 0.68/1000 visits; rate difference = 0.56, 95% confidence interval [CI] 0.51-0.61). Per 1000 clinical hours worked, physicians working in general EDs performed 0.26 procedures compared to 1.66 for physicians in pediatric EDs (rate difference = 1.39; 95% CI 1.27-1.52). CONCLUSION: Pediatric critical procedures are rarely performed by emergency physicians and are exceedingly rare in general EDs and freestanding EDs/urgent cares. The rarity of performance of these skills has implications for ED pediatric readiness.

Healthcare students interprofessional critical event/disaster response course.

OBJECTIVE: Numerous disasters confirm the need for critical event training in healthcare professions. However, no single discipline works in isolation and interprofessional learning is recognized as a necessary component. An interprofessional faculty group designed a learning curriculum crossing professional schools. DESIGN: Faculty members from four healthcare schools within the university (nursing, pharmacy, allied health, and medicine) developed an interdisciplinary course merging both published cross-cutting competencies for critical event response and interprofessional education competencies. SETTING: Students completed a discipline-specific online didactic course. Interdisciplinary groups then participated in a 4-hour synchronous experience. This live course featured high-fidelity medical simulations focused on resuscitation, as well as hands-on modules on decontamination and a mass casualty triage incorporating moulaged standardized patients in an active shooter scenario. PARTICIPANTS: Participants were senior students from allied health, medicine, nursing, and pharmacy. MAIN OUTCOME MEASURES: Precourse and postcourse assessments were conducted online to assess course impact on learning performance, leadership and team development, and course satisfaction. RESULTS: Students participated were 402. Precourse and postcourse evaluations showed improvement in team participation values, critical event knowledge, and 94 percent of participants reported learning useful skills. Qualitative responses evidenced positive response; most frequent recurring comments concerned value of interprofessional experiences in team communication and desire to incorporate this kind of education earlier in their curriculum. Students demonstrated improvement in both knowledge and attitudes in a critical event response course that includes interprofessional instruction and collaboration. Further study is required to demonstrate sustained improvement as well as benefit to clinical outcomes.

Stimulating reflective practice using collaborative reflective training in breaking bad news simulations.

Medical simulation has long been used as a way to immerse trainees in realistic practice scenarios to help them consolidate their formal medical knowledge and develop teamwork, communication, and technical skills. Debriefing is regarded as a critical aspect of simulation training. With a skilled debriefing facilitator, trainees are able to go beyond a rote review of the skills and steps taken to explore their internal process and self-reflect on how their experience during the simulation shaped their decision making and behavior. However, the sense of vulnerability is an aspect of experiential training that can raise a trainee's defensiveness. Anxiety increases when trainees anticipate being evaluated for their performance, or when the simulation scenario pertains to complex interpersonal activities such as learning how to break bad news (BBN), a commonly encountered aspect of medical practice with inadequate training. Thus, collaborative reflective training (CRT), developed out of ideas based in family therapy, was designed as an approach for facilitating open dialogue and greater self-reflection while receiving training in BBN. This article will discuss the conceptual framework of CRT, explain how it was developed, and describe the nature of how it was used with a team of neonatology and pediatric fellows and medical family therapy interns.

Characterizing novice-expert differences in macrocognition: an exploratory study of cognitive work in the emergency department.

STUDY OBJECTIVE: The objectives of this study are to elicit and document descriptions of emergency physician expertise, to characterize cognitive differences between novice and expert physicians, and to identify areas in which novices' skill and knowledge gaps are most pronounced. The nature of the differences between novices and experts needs to be explored to develop effective instructional modalities that accelerate the learning curve of inexperienced physicians who work in high-complexity environments. METHODS: We interviewed novice emergency physicians (first-year residents) and attending physicians with significant expertise, working in an academic Level I trauma center in Southern California. With cognitive task analysis, we used task diagrams to capture nonroutine critical incidents that required the use of complex cognitive skills. Timelines were constructed to develop a detailed understanding of challenging incidents and the decisions involved as the incident unfolded, followed by progressive deepening to tease out situation-specific cues, knowledge, and information that experts and novices used. A thematic analysis of the interview transcripts was conducted to identify key categories. Using classification techniques for data reduction, we identified a smaller set of key themes, which composed the core findings of the study. RESULTS: Five interns and 6 attending physicians participated in the interviews. Novice physicians reported having difficulties representing the patient's story to attending physicians and other health care providers. Overrelying on objective data, novice physicians use linear thinking to move to diagnosis quickly and are likely to discount and explain away data that do not "fit" the frame. Experienced physicians draw on expertise to recognize cues and patterns while leaving room for altering or even changing their initial diagnosis. Whereas experts maintain high levels of spatial, temporal, and organizational systems awareness when overseeing treatment modalities of multiple patients, novices have difficulty seeing and maintaining the "big picture." CONCLUSION: Novice physicians use sense-making styles that differ from those of experts. Training novices to respond to the high cognitive demand of complex environments early in their careers requires instructional modalities that not only increase their knowledge base but also accelerate the integration of knowledge and practice. Simulation and custom-designed avatar-mediated virtual worlds are a promising new technology that may facilitate such training. Future research should expand on the results of this study through the use of larger sample sizes and interviews conducted at multiple sites to increase generalizability.

Pediatric emergency department census during major sporting events.

OBJECTIVES: Our study attempted to evaluate the effects of major sporting events on the census of a pediatric emergency department (ED) in the United States specifically related to the National Football League Super Bowl, National Basketball Association (NBA) Finals, and Major League Baseball World Series. METHODS: We performed a retrospective data analysis of our pediatric ED census on the number of visits during major sporting events over a 5-year period. Data during the same period 1 week after the major sporting event were collected for comparison as the control. We evaluated the medians of 2-hour increments around the event start time. Subgroup analysis was performed for games involving the local sporting teams. RESULTS: Our results showed no significant difference in ED census during the sporting events, except in the post 6 to 8 hours of the NBA finals. Subgroup analysis of the Los Angeles Lakers showed the same significant findings in the post 6 to 8 hours of the NBA finals. CONCLUSIONS: No major difference in pediatric ED census is observed during the most major sporting events in the United States.

The role of morphine in a rat model of hypoxic-ischemic injury.

We investigated whether morphine plays a neuroprotective role in a neonatal rat pup model of bilateral carotid artery occlusion with hypoxia. At postnatal day 10, rats received either morphine (n = 7), naloxone (n = 7), or saline placebo (n = 15) after hypoxic-ischemic injury. Survival (days), weight gain and animal testing (negative geotaxis, surface righting, and rotarod) were compared between treatment groups. Lesion volume was delineated with magnetic resonance imaging at days 7 and 28-57 after injury. Survival in rats treated with morphine, naloxone, or saline was, respectively, 14, 29, and 73%. Median number of days of survival after bilateral carotid artery occlusion with hypoxia treated with morphine was 4 (95% confidence interval 4 to 22), with naloxone was 3 (95% confidence interval -1.4 to 21), and with placebo was 28 (95% confidence interval 18 to 28). There were no statistically significant differences in magnetic resonance imaging-derived ischemic lesion volumes, weight gain, or behavioral testing measures between the groups. Morphine was ineffective as a neuroprotectant in rat pups with severe hypoxic-ischemic injury and may have contributed to their decreased survival.

Simulation in medical school education: review for emergency medicine.

Medical education is rapidly evolving. With the paradigm shift to small-group didactic sessions and focus on clinically oriented case-based scenarios, simulation training has provided educators a novel way to deliver medical education in the 21st century. The field continues to expand in scope and practice and is being incorporated into medical school clerkship education, and specifically in emergency medicine (EM). The use of medical simulation in graduate medical education is well documented. Our aim in this article is to perform a retrospective review of the current literature, studying simulation use in EM medical student clerkships. Studies have demonstrated the effectiveness of simulation in teaching basic science, clinical knowledge, procedural skills, teamwork, and communication skills. As simulation becomes increasingly prevalent in medical school curricula, more studies are needed to assess whether simulation training improves patient-related outcomes.

Incidence of Serious Bacterial Infections in Ex-premature Infants with a Postconceptional Age Less Than 48 Weeks Presenting to a Pediatric Emergency Department.

OBJECTIVES: Premature infants are at higher risk of developing serious bacterial infections (SBI). However, the incidence of SBI in ex-premature infants presenting to the emergency department (ED) remains undetermined. The objective of this study is to examine the incidence of SBI in ex-premature infants with a postconceptional age of less than 48 weeks presenting to a pediatric ED. METHODS: A retrospective medical record review was conducted on 141 ex-premature infants with a postconceptional age of less than 48 weeks who had a full or partial septic work up completed in a pediatric ED between January 1, 1998 and March 31, 2005. RESULTS: The overall median gestational age at birth was 35 weeks (IQR 33-36 week) and the overall median postconceptional age at ED presentation was 40 weeks (IQR 37-42 weeks). Thirteen (9.2%) infants were found to have a SBI. Five subjects had pneumonia, four with bacteremia, two with pyelonephritis, and two with a concomitant infection of meningitis/pneumonia and bacteremia/pyelonephritis. CONCLUSION: The results of this study reveal that the incidence of SBI in ex-premature infants with a postconceptional age of less than 48 weeks is similar to in-term infants (9.2%) and is consistent with previously published incidence rates in-term infants (10%).

An educational course including medical simulation for early goal-directed therapy and the severe sepsis resuscitation bundle: an evaluation for medical student training.

OBJECTIVE: Widespread application of early goal-directed therapy (EGDT) and the severe sepsis resuscitation bundle is limited by clinician knowledge, skills and experience. This study evaluated use of simulation-based teaching during medical training to increase future clinician knowledge in the above therapies for severe sepsis and septic shock. METHODS: A prospective cohort study was performed with medical students at all levels of training. A 5-h course including didactic lectures, skill workshops, and a simulated case scenario of septic shock were administered to the participants. A checklist including 21 tasks was completed during the patient simulation. An 18-question pre-test, post-test and 2-week post-test were given. The participants completed a survey at the end of the course. RESULTS: Sixty-three students were enrolled. There was statistical difference between the pre-test and each of the post-test scores: 57.5+/-13.0, 85.6+/-8.8, and 80.9+/-10.9%, respectively. 20.6% of participants thought the pre-test was too difficult, whereas all participants thought the post-test was either appropriate or too easy. The task performance during the simulated septic shock patient was 94.1+/-6.0%. The participants noted improvements in their confidence levels at managing severe sepsis and septic shock, and agreed that the course should be a requirement during medical school training. CONCLUSIONS: Medical simulation is an effective method of educating EGDT and the severe sepsis resuscitation bundle to medical students with limited experience in patient care. The results suggest that our course may be of further benefit at increasing clinical experience with this intensive protocol for the management of severe sepsis and septic shock.

Adjunctive atropine is unnecessary during ketamine sedation in children.

BACKGROUND: The prophylactic coadministration of atropine or other anticholinergics during dissociative sedation has historically been considered mandatory to mitigate ketamine-associated hypersalivation. Emergency physicians (EPs) are known to omit this adjunct, so a prospective study to describe the safety profile of this practice was initiated. OBJECTIVES: To quantify the magnitude of excessive salivation, describe interventions for hypersalivation, and describe any associated airway complications. METHODS: In this prospective observational study of emergency department (ED) pediatric patients receiving dissociative sedation, treating physicians rated excessive salivation on a 100-mm visual analog scale and recorded the frequency and nature of airway complications and interventions for hypersalivation. RESULTS: Of 1,090 ketamine sedations during the 3-year study period, 947 (86.9%) were performed without adjunctive atropine. Treating physicians assigned the majority (92%) of these subjects salivation visual analog scale ratings of 0 mm, i.e., "none," and only 1.3% of ratings were >or= 50 mm. Transient airway complications occurred in 3.2%, with just one (brief desaturation) felt related to hypersalivation (incidence 0.11%, 95% confidence interval = 0.003% to 0.59%). Interventions for hypersalivation (most commonly suctioning) occurred in 4.2%, with no occurrences of assisted ventilation or intubation. CONCLUSIONS: When adjunctive atropine is omitted during ketamine sedation in children, excessive salivation is uncommon, and associated airway complications are rare. Anticholinergic prophylaxis is not routinely necessary in this setting.

Cutaneous community-associated methicillin-resistant staphylococcus aureus among all skin and soft-tissue infections in two geographically distant pediatric emergency departments.

OBJECTIVES: To describe the culture results of cutaneous infections affecting otherwise healthy children presenting to two pediatric emergency departments (EDs) in the southeastern United States and southern California. METHODS: Medical records of 920 children who presented to the pediatric EDs with skin infections and abscesses (International Classification of Diseases, Ninth Revision codes 680.0-686.9) during 2003 were reviewed. Chronically ill children with previously described risk factors for community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) were excluded. Data abstracted included the type of infection; the site of infection; and, if a culture was obtained, the organism grown, along with their corresponding sensitivities. RESULTS: Of the 270 children who had bacterial cultures obtained, 60 (22%) were CA-MRSA-positive cultures, most cultured from abscesses (80%). Of all abscesses cultured, CA-MRSA grew in more than half (53%). All CA-MRSA isolates tested were sensitive to vancomycin, trimethoprim-sulfamethoxazole, rifampin, and gentamicin. One isolate at each center was resistant to clindamycin. The sensitivities at both institutions were similar. CONCLUSIONS: The authors conclude that CA-MRSA is responsible for most abscesses and that the pattern of CA-MRSA infections in these geographically distant pediatric EDs is similar. These data suggest that optimal diagnostic and management strategies for CA-MRSA will likely be widely applicable if results from a larger, more collaborative study yield similar findings.

Ketamine to avoid mechanical ventilation in severe pediatric asthma.

Children experiencing severe asthma exacerbations may deteriorate to respiratory failure requiring endotracheal intubation and mechanical ventilation. Mechanical ventilation is often life saving in this setting, but also exposes the asthmatic child to substantial iatrogenic risk. We present two cases of severe asthma exacerbations in prepubertal children for whom the administration of a bolus of intravenous ketamine followed by a continuous infusion of a relatively large dose of ketamine led to prompt improvement, obviating the need for mechanical ventilation. These cases suggest that for children experiencing severe asthma exacerbations, intravenous ketamine may be an effective temporizing measure to avoid exposing these children to the risks associated with mechanical ventilation.

Procedural sedation use in the ED: management of pediatric ear and nose foreign bodies.

This is the first report of which we are aware that describes the use of procedural sedation for the emergency department management of ear and nose foreign bodies in children < 18 years of age. During a 5.5-year period, we identified 312 cases of children with a foreign body in a single orifice (174 ear, 138 nose). Procedural sedation was performed in 23% of cases (43 ear, 28 nose) and ketamine was used most commonly (92%). Emergency physicians had a high rate of success in removing foreign bodies (84% ear, 95% nose) and a low complication rate. Procedural sedation had a positive effect on the success rate as more than half of the sedation cases had undergone failed attempts without sedation by the same physician. Emergency physicians should have familiarity with this indication for procedural sedation.

The removal of coins from the upper esophageal tract of children by emergency physicians: a pilot study.

OBJECTIVE: There are few reports in the medical literature describing removal of a coin from the upper esophageal tract of a child by an emergency physician. However, given the nature of their training and practice, emergency physicians are well suited to perform this common procedure. We describe our experience with this procedure. METHODS: This was a retrospective review of a continuous quality improvement data set from a university-based tertiary care pediatric emergency department between Nov. 1, 2003, and Mar. 31, 2004. RESULTS: Thirteen children, with a median age of 20 months, underwent rapid sequence intubation and had coins successfully removed from their upper esophageal tract by emergency physicians. In 10 cases, the coin was visible at laryngoscopy and removed with Magill forceps. In 3 cases this approach failed and a Foley catheter was used to remove the coin. One child suffered a tonsillar abrasion and two sustained minor lip trauma, but all were extubated and discharged home from the emergency department with no significant complications. Eleven of the 13 patients were successfully followed up, and the parents reported no problems. CONCLUSIONS: This pilot study suggests that the removal of a coin from the upper esophageal tract by an emergency physician can be both safe and effective. A larger study is needed before this procedure can be generally recommended.

Investigation of afebrile neonates with a history of fever.

OBJECTIVE: Our objective was to describe clinically significant infections in a cohort of afebrile neonates who underwent an emergency department (ED) septic workup because of the history of a measured fever at home. METHODS: Retrospective medical record review of all infants (3/4)28 days of age who presented to our tertiary care pediatric ED between Jan. 1, 1999, and Aug. 22, 2002, underwent lumbar puncture in the ED, had a reported temperature at home of >or=38 degrees C, and an ED triage temperature of <38 degrees C. Laboratory and radiographic results were tabulated. RESULTS: During the study period, 206 neonates underwent lumbar puncture in our ED. Of these, 108 were excluded because their home temperature was not documented, and 71 were excluded because they were still febrile on presentation to the ED. The study group consisted of the remaining 27 subjects, 4 of whom had received acetaminophen prior to ED arrival. Infections were confirmed in 10 (37%) subjects (3 urinary tract infections, 2 aseptic meningitis, 1 enterovirus meningitis, 1 respiratory syncytial virus bronchiolitis, 1 rotavirus enteritis and 2 pneumonias). CONCLUSIONS: Clinically important infections are not uncommon among afebrile neonates undergoing ED septic workup because of a measured fever at home. Some diagnostic testing is warranted in this group, although the clinical utility and indications for specific test modalities remain unclear.

Intramuscular ketamine to facilitate pediatric central vascular access.

OBJECTIVES: Obtaining prompt vascular access in young children presenting to the emergency department (ED) is frequently both necessary and technically challenging. The objective of our study was to describe our experience using intramuscular (IM) ketamine to facilitate the placement of central venous catheters in children presenting to our ED needing vascular access in a timely fashion. METHODS: We performed a retrospective medical record review of all pediatric patients <18 years of age who presented to our tertiary care pediatric ED between May 1, 1998, and August 7, 2003, and underwent the placement of a central venous catheter facilitated by the use of IM ketamine. RESULTS: Eleven children met our inclusion criteria. Most of the children were young and medically complicated. The children ranged in age from 6 months to 8 years. The only complication identified was vomiting experienced by an 8-year-old boy. Emergency physicians successfully obtained central venous access in all subjects in the case series. CONCLUSIONS: The use of IM ketamine to facilitate the placement of central venous catheters in children who do not have peripheral venous access appears to be helpful. Emergency physicians may find it useful to be familiar with this use of IM ketamine.

Blunt pediatric head trauma requiring neurosurgical intervention: how subtle can it be?

Recent literature on pediatric head injuries has suggested that important intracranial injuries might present to the ED without typical signs or symptoms. The objective of our study was to review our institutional experience with head-injured infants and young children to assess the subtlety of the ED presentation. We performed a retrospective medical record review of head-injured children

Ventilatory response during dissociative sedation in children-a pilot study.

OBJECTIVES: It is unclear whether ketamine induces subclinical respiratory depression when administered in dissociative doses intravenously (IV). The authors report a pilot study of capnography in emergency department (ED) pediatric patients receiving ketamine alone for procedural sedation, and describe serial measures of ventilatory response [end-tidal carbon dioxide (EtCO(2)), respiratory rate, pulse oximetry]. METHODS: The authors performed continuous capnography on a convenience sample of 20 ED pediatric patients who received ketamine 1.5 mg/kg IV for procedural sedation. RESULTS: Continuous EtCO(2) and pulse oximetry remained essentially unchanged following ketamine injection, and no EtCO(2) levels > 47 mm Hg were noted at any point throughout sedation. CONCLUSIONS: No hypoventilation was observed in 20 ED pediatric patients receiving ketamine 1.5 mg/kg administered IV over 1 minute. The authors found no evidence of respiratory depressant properties for this dissociative agent.
