Symptomatic catheter-associated thrombosis in pediatric trauma patients: Choose your access wisely.

BACKGROUND: Traumatic injury and the presence of a central venous catheter are 2 of the strongest risk factors for venous thromboembolism in children. The purpose of this study was to determine the incidence of symptomatic, catheter-associated thrombosis in critically injured children. We hypothesized that femoral venous catheters are associated with a greater rate of thrombotic complications when compared with all other central venous access points. METHODS: We reviewed a retrospective cohort (2006-2016) of injured children (≤18 years) admitted to a pediatric intensive care unit with central access placed ≤7 days from admission. Symptomatic, catheter-associated thrombosis was determined by radiographic evidence. Poisson regression was used to compare the incidence of catheter-associated thrombosis per 1,000 catheter days between femoral and nonfemoral catheters. All comparisons were 2-tailed with α = 0.05. RESULTS: We examined 209 pediatric trauma patients with central access (65% femoral, 19% subclavian, 11% arm vein, and 5% internal jugular). Femoral catheters were removed earlier (median [interquartile range] 4 [2-7] vs 8 [3-12] days, P < .001) and were larger in diameter (5 Fr [4-7] vs 4 Fr [4-4], P < .001) when compared with all other catheters. Catheter-associated thrombosis was more frequent in femoral versus nonfemoral catheters (18.4 vs 3.5 per 1,000 catheter days, P = .01). CONCLUSION: Femoral venous catheters are associated with a greater incidence of symptomatic, catheter-associated thrombosis in pediatric trauma patients. When central venous access is indicated for injured children, the femoral site should be avoided. If a femoral venous catheter is necessary, use of a smaller catheter should be considered.

Interactive Education is Associated With Lower Incidence of Pedestrian-Related Injury in Children.

BACKGROUND: Pedestrian-related injuries are a significant contributor to preventable mortality and disability in children. We hypothesized that interactive pedestrian safety education is associated with increased knowledge, safe crosswalk behaviors, and lower incidence of pedestrian-related injuries in elementary school-aged children. METHODS: An interactive street-crossing simulation was implemented at target elementary schools in Los Angeles County beginning in 2009. Mixed-methods were used to evaluate the impact of this intervention. Multiple-choice examinations were used to test pedestrian safety knowledge, anonymous observations were used to assess street-crossing behaviors, and statewide traffic records were used to report pedestrian injuries in elementary school-aged (4-11 y) children in participating school districts. Pedestrian injury incidence was compared 1 y before and after the intervention, standardized to the incidence in the entire City of Los Angeles. RESULTS: A total of 1424 and 1522 children completed the pretest and post-test, respectively. Correct answers increased for nine of ten questions (all P < 0.01). Children more frequently looked both ways before crossing the street after the intervention (10% versus 41%, P < 0.001). There were 6 reported pedestrian-related injuries in intervention school districts in the year before the intervention and 2 injuries in the year after the intervention, resulting in a significantly lower injury incidence (standardized rate ratio 0.28; 95% CI, 0.11-0.73). CONCLUSION: Pedestrian safety education at Los Angeles elementary schools was associated with increased knowledge, safe street-crossing behavior, and lower incidence of pediatric pedestrian-related injury. Formal pedestrian safety education should be considered with injury prevention efforts in similar urban communities.

Multidisciplinary Simulation-Based Team Training for Trauma Resuscitation: A Scoping Review.

OBJECTIVE: Simulation-based training as an educational intervention for healthcare providers has increased in use over the past 2 decades. The simulation community has called for standardized reporting of methodologies and outcomes. The purpose of this review was to (1) summarize existing data on the use of simulation-based team training for acute trauma resuscitation, and (2) describe differences in training methodologies, outcomes reporting, and gaps in the literature to inform research priorities. DESIGN: We performed a scoping review of Ovid Medline, Embase, Cochrane Library, CINAHL, Web of Science, ERIC, and Google Scholar for studies evaluating simulation-based team training for acute trauma resuscitation. Full-text review was performed by 2 reviewers and variables related to study design, training methodology, outcomes reported, and impact of training were abstracted. RESULTS: Forty-seven out of 3,911 screened studies met criteria for inclusion. Only 2 studies were randomized. The most frequent design was a pre-post study (64%). Eleven studies did not report their simulated scenario design. Interventions occurred most frequently in a laboratory-based setting (45%). Simulation-based training was associated with greater knowledge (n = 5/6), higher nontechnical skills (n = 12/13), greater number of resuscitation tasks completed (n = 10/13), and faster time to resuscitation task completion (n = 11/11). No differences in patient outcomes were found (n = 3/3). CONCLUSIONS: Simulation-based training for trauma resuscitation is associated with improved measures of teamwork, task performance and speed, knowledge, and provider satisfaction. Type of reported outcomes and training methodologies are variable. Standardized reporting of training methodology and outcomes is needed to address the impact of this intervention.

Formative research experiences in pediatric surgeons: a mixed methods study of Pediatric Trauma Society members.

PURPOSE: A career in pediatric surgery has historically required extensive research experience, but the optimal research training is not well defined. The purpose of this study was to explore the formative research experiences among pediatric surgeons. METHODS: A 1-h focus group was held with 14 pediatric surgeons at the 2017 Pediatric Trauma Society annual meeting. A 17-item survey was also administered. Questions were intended to elicit discussion of prior research experiences. A qualitative analysis of the dialogue was performed. RESULTS: Seventy-seven percent of respondents completed a research fellowship. Most (77%) currently conduct clinical research. Participants most frequently desired additional training in study design (50%), NIH funding (43%), and grant preparation (43%). Seven themes were identified from the focus group: (1) Early research exposure is rudimentary; (2) Resume-building was a motivation; (3) Mentorship is important; (4) Institutional resources are vital; (5) Independent learning is necessary; (6) Protected time is limited; and (7) Basic science research is not always practical. CONCLUSIONS: Many pediatric surgeons feel that their research training can be improved upon. Formal mentorship, dedicated research time, and institutional resources were perceived to be important factors. Education in research study design, grant writing, and NIH funding may be beneficial. LEVEL OF EVIDENCE: V, expert opinion.

Simulation-based training for trauma resuscitation among ACS TQIP-Pediatric centers: Understanding prevalence of use, associated center characteristics, training factors, and implementation barriers.

BACKGROUND: Simulation-based training (SBT) for pediatric trauma resuscitation can improve team performance. The purpose of this study was to describe the nationwide trend in SBT use and barriers to SBT implementation. METHODS: Trauma centers that participated in ACS TQIP Pediatric in 2016 (N = 125) were surveyed about SBT use. Center characteristics and reported implementation barriers were compared between centers using and not using SBT. RESULTS: Survey response rate was 75% (94/125) with 78% (73/94) reporting SBT use. The frequency of pediatric SBT use increased from 2014 to 2016 (median 5.5 vs 6.5 annual sessions, p < 0.01). Funding barriers were negatively associated with number of annual SBT sessions (r ≤ -0.34, p < 0.05). Centers not using SBT reported lack of technical expertise (p = 0.01) and lack of data supporting SBT (p = 0.03) as significant barriers. CONCLUSIONS: Simulation use increased from 2014 to 2016, but significant barriers to implementation exist. Strategies to share resources and decrease costs may improve usage. LEVEL OF EVIDENCE: Level 3, epidemiological.

Pediatric firearm injuries in Los Angeles County: Younger children are more likely to be the victims of unintentional firearm injury.

BACKGROUND: Firearm injuries are now the third leading cause of death in children. Understanding the circumstances surrounding pediatric firearm injuries will allow for targeted injury prevention efforts. We hypothesized that younger children are more likely to be victims of unintentional firearm injury. METHODS: A multicenter, retrospective review of patients <18 years old who sustained firearm injuries in Los Angeles County from 2006 to 2015 was performed. Unintentional injuries were defined as accidental firearm discharge without violent intent. Intentional injuries were defined as firearm discharge with intent to injure (including suicide). RESULTS: After review of 304 pediatric firearm injuries, 206 had sufficient narrative to determine intent with 10% of injuries classified as unintentional. Unintentional injuries were more common in younger children, more frequently caused by a firearm from within the home, and more likely to involve friend/family (all p < 0.05). Intentional injuries were associated with more injuries and accounted for all deaths in our study cohort. CONCLUSIONS: In pediatric firearm injury, younger children are more susceptible to unintentional injuries, but intentional injuries are more common overall. Future interventions need to target both intentional violence in older children and unintentional firearm injury in young children if the frequency is to be reduced. TYPE OF STUDY: Epidemiologic study. LEVEL OF EVIDENCE: Level III.

Impact of simulation-based training on perceived provider confidence in acute multidisciplinary pediatric trauma resuscitation.

PURPOSE: Simulation-based training has the potential to improve team-based care. We hypothesized that implementation of an in situ multidisciplinary simulation-based training program would improve provider confidence in team-based management of severely injured pediatric trauma patients. METHODS: An in situ multidisciplinary pediatric trauma simulation-based training program with structured debriefing was implemented at a free-standing children's hospital. Trauma providers were anonymously surveyed 1 month before (pre-), 1 month after (post-), and 2 years after implementation. RESULTS: Survey response rate was 49% (n = 93/190) pre-simulation, 22% (n = 42/190) post-simulation, and 79% (n = 150/190) at 2-year follow-up. These providers reported more anxiety (p = 0.01) and less confidence (p = 0.02) 1-month post-simulation. At 2-year follow-up, trained providers reported less anxiety (p = 0.02) and greater confidence (p = 0.01), compared to untrained providers. CONCLUSIONS: Implementation of an in situ multidisciplinary pediatric trauma simulation-based training program may initially lead to increased anxiety, but long-term exposure may lead to greater confidence. LEVEL OF EVIDENCE: II, Prospective cohort.

Heads Up, Phones Down: A Pedestrian Safety Intervention on Distracted Crosswalk Behavior.

Cell phone use has been implicated in driver distraction and motor vehicle crashes, and more recently has been associated with distracted pedestrians. There are limited data on interventions aimed at this important public health issue. We hypothesized that the use of a visual intervention near street crossings would decrease the frequency of distracted behaviors of pedestrians. We performed a prospective observational cohort study examining painted sidewalk stencils reading, "Heads Up, Phones Down" as an intervention to decrease cell phone distractions amongst pedestrians. These stenciled messages were placed at a children's hospital, middle school, and high school in Los Angeles County. Anonymous observations of pedestrian distractions (texting, talking on a phone, headphone use, and other) were conducted before, 1 week after, and 4 months after the intervention. Distractions were compared before and after intervention using Chi square tests. A total of 11,533 pedestrians were observed, with 71% children and 29% adults. Total distractions decreased from 23% pre-intervention to 17% 1 week after stencil placement (p < 0.01), but this was not sustained at 4 months (23%, p = 0.4). A sustained decrease was observed only for texting at 4 months post-intervention (8.5% vs. 6.8%, p < 0.01). A simple visual intervention reduced distracted cell phone usage in pedestrians crossing the street, but this was most effective early after the intervention. Future studies are warranted to determine how to sustain this effect over time and how to minimize other types of distractions.

Preoperative Educational Intervention Decreases Unplanned Gastrostomy-Related Health Care Utilization.

Apprehension in taking independent care of children with medical devices may lead to unnecessary visits to the ED and/or acute clinic (AC). To address these concerns, our institution implemented a gastrostomy tube (GT) class in 2011 for caretakers. We hypothesized that inappropriate GT-related ED/AC visits would be lower in preoperatively educated caregivers. We performed a retrospective cohort study of all patients aged 0 to 18 who received GT (surgical or percutaneous) at our institution between 2006 and 2015 (n = 1340). Class attendance (trained vs untrained) and unscheduled GT-related ED/AC visits one year after GT placement were reviewed. Gastrostomy-related ED/AC visits were classified as appropriate (hospital-based intervention) or inappropriate (site care and education/reassurance). Occurrence of ED/AC visits was compared between trained and untrained cohorts. We found that 59 per cent of patients had an unscheduled GT-related ED/AC visit within one year of placement. The trained cohort had 27 per cent less unplanned ED/AC visits within one year (mean 1.21 (SD 1.82) vs untrained 1.65 (2.24), P < 0.001). On multivariate analysis, GT education independently decreased one-year GT-related health care utilization (Odds Ratio 0.75, 95% Confidence Interval 0.59-0.95). Formal education seems to decrease GT-related health care utilization within one year of placement and should be integrated into a comprehensive care plan to improve caregiver self-efficacy.
