Effect of Family Presence on Advanced Trauma Life Support Task Performance During Pediatric Trauma Team Evaluation.

IMPORTANCE: In many hospitals, family members are separated from their children during the early phases of trauma care. Including family members during this phase of trauma care varies by institution and is limited by concerns for adverse effects on clinical care. OBJECTIVE: The aim of this study is to evaluate the effect of family presence (FP) on advanced trauma life support primary and secondary survey task performance by pediatric trauma teams. We hypothesized that trauma care with FP would be noninferior to care when families were absent. DESIGN: We performed a retrospective video review of consecutive pediatric trauma evaluations. Family presence status was determined by availability of the family. SETTING: The study was conducted at an American College of Surgeons-designated level I pediatric trauma center that serves the Washington, DC, metropolitan area. PARTICIPANTS: Participants included patients younger than 16 years of age who met trauma activation criteria and were evaluated by the trauma team in our emergency department. OUTCOME MEASURES: We compared task performance between patients with and without FP. RESULTS: Video recordings of 135 trauma evaluations were reviewed. Family was present for 88 (65%) evaluations. Patients with FP were younger (mean age, 6.4 years [SD = 4.1] vs 9.0 years [SD = 4.9]; P < 0.001) and more likely to have sustained blunt injuries (95% vs 85%, P = 0.03). Noninferiority of frequency and timeliness of completion of all primary survey tasks were confirmed for evaluations with FP. Noninferiority of frequencies of secondary survey task completion was confirmed for most tasks except for examination of the neck, pelvis, and upper extremities. Family members did not directly interfere with patient care in any case. CONCLUSIONS: Performance of most advanced trauma life support tasks during pediatric trauma evaluation was not worsened by FP. Our data provide additional evidence supporting FP during the acute management of injured children.

Assessment of the Need for Immediate Trauma Team Presence for Infants Presenting in Cardiac Arrest.

OBJECTIVES: Out-of-hospital cardiac arrest (OHCA) is rare in infants, with the cause of arrest often unknown upon presentation. Nonaccidental trauma is a potential etiology of OHCA among infants, but its occult presentation makes this etiology challenging to diagnose. In the absence of apparent injuries, identifying the need for trauma team activation is difficult during the initial resuscitation of infants with OHCA. METHODS: We performed a retrospective chart review of infants younger than 1 year old who presented to Children's National Health System from 2012 to 2016 with cardiopulmonary resuscitation in progress. Medical records and the trauma registry were reviewed for relevant resuscitation information. Autopsy records provided the cause and manner of death, contributing factors to death, and evidence of injury. RESULTS: Among 592 infants undergoing resuscitation during the study period, 34 infants (5.7%) presented in cardiac arrest. The average age on presentation was 101.2 days (standard deviation 78.7). Most of the patients (n = 32, 94.1%) died in the emergency department, with none surviving to discharge. Among the 32 infants for whom autopsy records were available, the cause of death was nonaccidental trauma in one patient (3.1%). CONCLUSIONS: Infant OHCA had poor outcomes, with trauma as a rare etiology. In the absence of external signs of injury or known injury mechanism, immediate trauma team presence was not beneficial for these infants during the initial resuscitation phase.

Use of Payer as a Proxy for Health Insurance Status on Admission Results in Misclassification of Insurance Status among Pediatric Trauma Patients.

The purpose of this study was to quantify health insurance misclassification among children treated at a pediatric trauma center and to determine factors associated with misclassification. Demographic, medical, and financial information were collected for patients at our institution between 2008 and 2010. Two health insurance variables were created: true (insurance on hospital admission) and payer (source of payment). Multivariable logistic regression was used to determine which factors were independently associated with health insurance misclassification. The two values of health insurance status were abstracted from the hospital financial database, the trauma registry, and the patient medical record. Among 3630 patients, 123 (3.4%) had incorrect health insurance designation. Misclassification was highest in patients who died: 13.9 per cent among all deaths and 30.8 per cent among emergency department deaths. The adjusted odds of misclassification were 6.7 (95% confidence interval: 1.7, 26.6) among patients who died and 16.1 (95% confidence interval: 3.2, 80.77) among patients who died in the emergency department. Using payer as a proxy for health insurance results in misclassification. Approaches are needed to accurately ascertain true health insurance status when studying the impact of insurance on treatment outcomes.

Effect of a checklist on advanced trauma life support task performance during pediatric trauma resuscitation.

OBJECTIVES: Advanced Trauma Life Support (ATLS) has been shown to improve outcomes related to trauma resuscitation; however, omissions from this protocol persist. The objective of this study was to evaluate the effect of a trauma resuscitation checklist on performance of ATLS tasks. METHODS: Video recordings of resuscitations of children sustaining blunt or penetrating injuries at a Level I pediatric trauma center were reviewed for completion and timeliness of ATLS primary and secondary survey tasks, with and without checklist use. Patient and resuscitation characteristics were obtained from the trauma registry. Data were collected during two 4-month periods before (n = 222) and after (n = 213) checklist implementation. The checklist contained 50 items and included four sections: prearrival, primary survey, secondary survey, and departure plan. RESULTS: Five primary survey ATLS tasks (cervical spine immobilization, oxygen administration, palpating pulses, assessing neurologic status, and exposing the patient) and nine secondary survey ATLS tasks were performed more frequently (p ≤ 0.01 for all) and vital sign measurements were obtained faster (p ≤ 0.01 for all) after the checklist was implemented. When controlling for patient and event-specific characteristics, primary and secondary survey tasks overall were more likely to be completed (odds ratio [OR] = 2.66, primary survey; OR = 2.47, secondary survey; p < 0.001 for both) and primary survey tasks were performed faster (p < 0.001) after the checklist was implemented. CONCLUSIONS: Implementation of a trauma checklist was associated with greater ATLS task performance and with increased frequency and speed of primary and secondary survey task completion.

Factors affecting team size and task performance in pediatric trauma resuscitation.

OBJECTIVES: Varying team size based on anticipated injury acuity is a common method for limiting personnel during trauma resuscitation. While missing personnel may delay treatment, large teams may worsen care through role confusion and interference. This study investigates factors associated with varying team size and task completion during trauma resuscitation. METHODS: Video-recorded resuscitations of pediatric trauma patients (n = 201) were reviewed for team size (bedside and total) and completion of 24 resuscitation tasks. Additional patient characteristics were abstracted from our trauma registry. Linear regression was used to assess which characteristics were associated with varying team size and task completion. Task completion was then analyzed in relation to team size using best-fit curves. RESULTS: The average bedside team ranged from 2.7 to 10.0 members (mean, 6.5 [SD, 1.7]), with 4.3 to 17.7 (mean, 11.0 [SD, 2.8]) people total. More people were present during high-acuity activations (+4.9, P < 0.001) and for patients with a penetrating injury (+2.3, P = 0.002). Fewer people were present during activations without prearrival notification (-4.77, P < 0.001) and at night (-1.25, P = 0.002). Task completion in the first 2 minutes ranged from 4 to 19 (mean, 11.7 [SD, 3.8]). The maximum number of tasks was performed at our hospital by teams with 7 people at the bedside (13 total). CONCLUSIONS: Resuscitation task completion varies by team size, with a nonlinear association between number of team members and completed tasks. Management of team size during high-acuity activations, those without prior notification, and those in which the patient has a penetrating injury may help optimize performance.

Effect of a checklist on advanced trauma life support workflow deviations during trauma resuscitations without pre-arrival notification.

BACKGROUND: Trauma resuscitations without pre-arrival notification are often initially chaotic, which can potentially compromise patient care. We hypothesized that trauma resuscitations without pre-arrival notification are performed with more variable adherence to ATLS protocol and that implementation of a checklist would improve performance. STUDY DESIGN: We analyzed event logs of trauma resuscitations from two 4-month periods before (n = 222) and after (n = 215) checklist implementation. Using process mining techniques, individual resuscitations were compared with an ideal workflow model of 6 ATLS primary survey tasks performed by the bedside evaluator and given model fitness scores (range 0 to 1). Mean fitness scores and frequency of conformance (fitness = 1) were compared (using Student's t-test or chi-square test, as appropriate) for activations with and without notification both before and after checklist implementation. Multivariable linear regression, controlling for patient and resuscitation characteristics, was also performed to assess the association between pre-arrival notification and model fitness before and after checklist implementation. RESULTS: Fifty-five (12.6%) resuscitations lacked pre-arrival notification (23 pre-implementation and 32 post-implementation; p = 0.15). Before checklist implementation, resuscitations without notification had lower fitness (0.80 vs 0.90; p < 0.001) and conformance (26.1% vs 50.8%; p = 0.03) than those with notification. After checklist implementation, the fitness (0.80 vs 0.91; p = 0.007) and conformance (26.1% vs 59.4%; p = 0.01) improved for resuscitations without notification, but still remained lower than activations with notification. In multivariable analysis, activations without notification had lower fitness both before (b = -0.11, p < 0.001) and after checklist implementation (b = -0.04, p = 0.02). CONCLUSIONS: Trauma resuscitations without pre-arrival notification are associated with a decreased adherence to key components of the ATLS primary survey protocol. The addition of a checklist improves protocol adherence and reduces the effect of notification on task performance.

Improving ATLS performance in simulated pediatric trauma resuscitation using a checklist.

OBJECTIVE: To develop a checklist for use during pediatric trauma resuscitation and test its effectiveness during simulated resuscitations. BACKGROUND: Checklists have been used to support a wide range of complex medical activities and have effectively reduced errors and improved outcomes in different medical settings. Checklists have not been evaluated in the domain of trauma resuscitation. METHODS: A focus group of trauma specialists was organized to develop a checklist for pediatric trauma resuscitation. This checklist was then tested in simulated trauma resuscitations to evaluate its impact on team performance. Resuscitations conducted with and without the checklist were compared using the Advanced Trauma Life Support (ATLS) performance score, designed to measure adherence to ATLS protocol, and surveys of team members' subjective workload. RESULTS: The focus group generated a checklist with 56 items divided into 5 sections corresponding to different phases of trauma resuscitation. In simulation testing, the total ATLS performance score was 4.9 points higher with a checklist than without (P < 0.001), with most of this difference related to improvement in performance of the secondary survey (+3.3 points, P < 0.001). Overall, workload scores were not affected by the addition of the checklist. CONCLUSIONS: Implementing a checklist during simulated pediatric trauma resuscitation improves adherence to the ATLS protocol without increasing the workload of trauma team members.

Factors associated with patient exposure and environmental control during pediatric trauma resuscitation.

BACKGROUND: Exposure and environmental control are essential components of the advanced trauma life support primary survey, especially during the resuscitation of pediatric patients. Proper exposure aids in early recognition of injuries in patients unable to communicate their injuries, while warming techniques, such as the use of blankets, assist in maintaining normothermia. The purpose of this study was to identify factors associated with exposure compliance and duration during pediatric trauma resuscitation. METHODS: All pediatric trauma resuscitations over a 4-month period were reviewed for compliance and time to completion of clothing removal and warm blanket placement. Video review data were then linked with clinical data obtained from the trauma registry. Univariate and multivariate analyses were used to determine the associations of patient characteristics, injury mechanism, and clinical factors on exposure compliance and duration. RESULTS: Of 145 patients, 65 (52%) were never exposed. Lower exposure compliance was associated with increasing age (odds ratio, [OR], 0.90; 95% confidence interval [CI], 0.83-0.98), Glasgow Coma Scale (GCS) score of 14 or greater (OR, 0.16; 95% CI, 0.03-0.76), Injury Severity Score (ISS) of 15 or less (OR, 0.27; 95% CI, 0.09-0.82), and the absence of head injury (OR, 0.26; 95% CI, 0.08-0.87). Among those exposed, the duration of exposure was longer among children with GCS score of less than 14 (4.3 [1.6], p = 0.009), head injuries (3.33 [1.6], p = 0.04), and the need for intubation (8.4 [2.2], p < 0.001). In multivariate analyses, older age and ISS of 15 or less were associated with a decreased odds of exposure (p = 0.009, p = 0.04, respectively), while intubation was associated with increased exposure duration (p = 0.007). CONCLUSION: Despite the importance of exposure and environmental control during pediatric trauma resuscitation, compliance with these tasks was low, even among severely injured patients. Interventions are needed to promote the proper exposure of patients during the initial evaluation, while also limiting the duration of exposure during examinations and procedures in the trauma bay. LEVEL OF EVIDENCE: Epidemiologic study, level III.

Adherence to ATLS primary and secondary surveys during pediatric trauma resuscitation.

STUDY AIM: Adherence to Advanced Trauma Life Support (ATLS) protocol has been associated with improved management of injured patients. The objective of this study is to determine factors associated with delayed and omitted ATLS primary and secondary survey tasks at a level 1 pediatric trauma center. METHODS: Video recorded resuscitations of 237 injured patients <18 years old obtained over a four month period at our hospital were evaluated to assess completeness and timeliness of essential tasks in the primary and secondary survey of ATLS. Multivariate analyses were performed to identify features associated with decreased ATLS performance. RESULTS: Primary survey findings were stated less often in patients with burn injuries compared to those with blunt injuries (RR=1.72; 95% CI: 1.26-2.35) and less often during the overnight shift [11 PM-7 AM] (RR=1.22; 95% CI: 1.02-1.46). Secondary survey findings were verbalized less often in patients with penetrating injures (RR=2.30; 95% CI: 1.06-5.00). Time to statement of primary surveys findings was delayed in patients with burn injuries (HR=0.69; 95% CI: 0.48-0.98) and among those transferred from another hospital. Completeness and timeliness of ATLS task performance were not associated with age or injury severity score. CONCLUSIONS: Mechanism of injury and hospital factors are associated with incomplete and delayed primary and secondary surveys. Interventions that address deficient ATLS adherence related to these factors may lead to a reduction in errors during this critical period of patient care.

Compliance with barrier precautions during paediatric trauma resuscitations.

PURPOSE: Barrier precautions protect patients and providers from blood-borne pathogens. Although barrier precaution compliance has been shown to be low among adult trauma teams, it has not been evaluated during paediatric resuscitations in which perceived risk of disease transmission may be low. The purpose of this study was to identify factors associated with compliance with barrier precautions during paediatric trauma resuscitations. METHODS: Video recordings of resuscitations performed on injured children (<18 years old) were reviewed to determine compliance with an established policy requiring gowns and gloves. Depending on activation level, trauma team members included up to six physicians, four nurses, and a respiratory therapist. Multivariate logistic regression was used to determine the effect of team role, resuscitation factors, and injury mechanism on barrier precaution compliance. RESULTS: Over twelve weeks, 1138 trauma team members participated in 128 resuscitations (4.7% penetrating injuries, 9.4% highest level activations). Compliance with barrier precautions was 81.3%, with higher compliance seen among roles primarily at the bedside compared to positions not primarily at the bedside (90.7% vs. 65.1%, p<0.001). Bedside residents (98.4%) and surgical fellows (97.6%) had the highest compliance, while surgical attendings (20.8%) had the lowest (p<0.001). Controlling for role, increased compliance was observed during resuscitations of patients with penetrating injuries (OR=3.97 [95% CI: 1.35-11.70], p=0.01), during resuscitations triaged to the highest activation level (OR=2.61 [95% CI: 1.34-5.10], p=0.005), and among team members present before patient arrival (OR=4.14 [95% CI: 2.29-7.39], p<0.001). CONCLUSIONS: Compliance with barrier precautions varies by trauma team role. Team members have higher compliance when treating children with penetrating and high acuity injuries and when arriving before the patient. Interventions integrating barrier precautions into the workflow of team members are needed to reduce this variability and improve compliance with universal precautions during paediatric trauma resuscitations.

Assessment of workload during pediatric trauma resuscitation.

BACKGROUND: Trauma resuscitations are high-pressure, time-critical events during which health care providers form ad hoc teams to rapidly assess and treat injured patients. Trauma team members experience varying levels of workload during resuscitations resulting from the objective demands of their role-specific tasks, the circumstances surrounding the event, and their individual previous experiences. The goal of this study was to determine factors influencing workload experienced by trauma team members during pediatric trauma resuscitations. METHODS: Workload was measured using the National Aeronautics and Space Administration Task Load Index (TLX). TLX surveys were administered to four trauma team roles: charge nurse, senior surgical resident (surgical coordinator), emergency medicine physician, and junior surgical resident or nurse practitioner (bedside clinician). A total of 217 surveys were completed. Univariate and multivariate statistical techniques were used to examine the relationship between workload and patient and clinical factors. RESULTS: Bedside clinicians reported the highest total workload score (208.7), followed by emergency medicine physicians (156.3), surgical coordinators (144.1), and charge nurses (129.1). Workload was higher during higher-level activations (235.3), for events involving intubated patients (249.0), and for patients with an Injury Severity Score greater than 15 (230.4) (p, 0.001 for all). When controlling for potential confounders using multiple linear regression, workload was increased during higher level activations (79.0 points higher, p = 0.01) and events without previous notification (38.9 points higher, p = 0.03). Workload also remained significantly higher for the bedside clinician compared with the other three roles (p ≤ 0.005 for all). CONCLUSION: Workload during pediatric trauma resuscitations differed by team role and was increased for higher-level activations and events without previous notification. This study demonstrates the validity of the TLX as a tool to measure workload in trauma resuscitation. LEVEL OF EVIDENCE: Prognostic study, level II.

Leadership structures in emergency care settings: a study of two trauma centers.

BACKGROUND: Trauma resuscitation involves multidisciplinary teams under surgical leadership in most US trauma centers. Because many trauma centers have also incorporated emergency department (ED) physicians, shared and cross-disciplinary leadership structures often occur. Our study identifies leadership structures and examines the effects of cross-disciplinary leadership on trauma teamwork. METHODS: We conducted an ethnographic study at two US Level-1 trauma centers, one of which is a dedicated pediatric trauma center. We used observation, videotaping and interviews to contextualize and classify leadership structures in trauma resuscitation. Leadership structures were evaluated based on three dimensions of team performance: defined leadership, likelihood of conflict in decision making, and appropriate care. FINDINGS: We identified five common leadership structures, grouped under two broad leadership categories: solo decision-making and intervening models within intra-disciplinary leadership; intervening, parallel, and collaborative models within cross-disciplinary leadership. CONCLUSION: Most important weaknesses of different leadership structures are manifested in inefficient teamwork or inappropriate patient care. These inefficiencies are particularly problematic when leadership is shared between physicians from different disciplines with different levels of experience, which often leads to conflict, reduces teamwork efficiency and lowers the quality of care. We discuss practical implications for technology design.
