Blood component use and injury characteristics of acute trauma patients arriving from the scene of injury or as transfers to a large, mature US Level 1 trauma center serving a large, geographically diverse region.

BACKGROUND: Advanced trauma care demands the timely availability of hemostatic blood products, posing special challenges for regional systems in geographically diverse areas. We describe acute trauma blood use by transfer status and injury characteristics at a large regional Level 1 trauma center. STUDY DESIGN AND METHODS: We reviewed Harborview Medical Center (HMC) Trauma Registry, Transfusion Service, and electronic medical records on acute trauma patients for demographics, injury patterns, blood use, and in-hospital mortality, 2011-2019. RESULTS: Among 47,471 patients (mean age 45.2 ± 23.0 years; 68.3% male; Injury Severity Score 12.6 ± 11.1), 4.7% died and 8547 (18%) received at least one blood component through HMC. Firearms injuries were the most often transfused (690/2596, 26.6%) and the most urgently (39.9% ≥3 units in <1 h; 40.6% ≥5 units in <4 h), and had the highest mortality (case-fatality, 12.2%) (all p < .001). From-scene patients were younger than transfers (42.9 ± 21.0 vs. 47.2 ± 24.4), predominated among firearms injuries (68.2% from-scene vs. 31.8% transfers), were more likely to receive blood (18.5% vs. 17.6%) more urgently (≥3 units first hour, 24.4% vs. 7.7%; ≥5 units first 4 h: 25.6% vs. 8.2%), were more likely to die of hemorrhage (15.5% vs. 4.3%) and from firearms injuries (310/1360, 22.8%) (all p < .001). DISCUSSION: Early blood use, firearms injuries, and mortality were all greater among from-scene patients, and firearms injuries had worse outcomes despite greater and more urgent blood use, but the role of survivor bias for transfer patients must be clarified. Future research must identify strategies for providing local hemostatic transfusion support, particularly for firearms injuries.

Targeted areas for improving health literacy after traumatic brain injury.

OBJECTIVE: To develop a framework to identify targeted areas for improving health literacy for caregivers after traumatic brain injury (TBI). METHOD: Qualitative study using inductive and deductive qualitative content analysis was conducted in a large, urban, level I trauma centre. Interviews were conducted with 23 caregivers of persons with TBI. Participants' perspectives on communication and preparation for discharge were explored and understanding of commonly used words and discharge instructions were assessed. RESULTS: Four types of communication patterns were identified: formal, informal, indirect and caregiver-initiated. Informal and caregiver-initiated communication were the most common. All caregivers reported confusion about their family member's condition, care plan or discharge plan. Caregivers were not able to define commonly used terms in discharge instructions, and were confused by formatting and medical language. Caregivers were not aware of expected caregiving roles upon discharge. Conceptualizing findings within a family-centred care model, we offer specific strategies to improve health communication and caregiver capacity building to enhance health literacy. CONCLUSIONS: Health literacy and caregiver capacity to care for loved ones with TBI after hospital discharge is low. We offer specific target areas for improvement in verbal and written communication and capacity building that take into account provider, patient and family characteristics.

Impact of social and technological distraction on pedestrian crossing behaviour: an observational study.

OBJECTIVES: The objective of the present work was to study the impact of technological and social distraction on cautionary behaviours and crossing times in pedestrians. METHODS: Pedestrians were observed at 20 high-risk intersections during 1 of 3 randomly assigned time windows in 2012. Observers recorded demographic and behavioural information, including use of a mobile device (talking on the phone, text messaging, or listening to music). We examined the association between distraction and crossing behaviours, adjusting for age and gender. All multivariate analyses were conducted with random effect logistic regression (binary outcomes) and random effect linear regression (continuous outcomes), accounting for clustering by site. RESULTS: Observers recorded crossing behaviours for 1102 pedestrians. Nearly one-third (29.8%) of all pedestrians performed a distracting activity while crossing. Distractions included listening to music (11.2%), text messaging (7.3%) and using a handheld phone (6.2%). Text messaging, mobile phone use and talking with a companion increased crossing time. Texting pedestrians took 1.87 additional seconds (18.0%) to cross the average intersection (3.4 lanes), compared to undistracted pedestrians. Texting pedestrians were 3.9 times more likely than undistracted pedestrians to display at least 1 unsafe crossing behaviour (disobeying the lights, crossing mid-intersection, or failing to look both ways). Pedestrians listening to music walked more than half a second (0.54) faster across the average intersection than undistracted pedestrians. CONCLUSIONS: Distracting activity is common among pedestrians, even while crossing intersections. Technological and social distractions increase crossing times, with text messaging associated with the highest risk. Our findings suggest the need for intervention studies to reduce risk of pedestrian injury.

Concussion symptoms and temporary accommodations using a student-centered return to learn care plan.

BACKGROUND: Many students return to school after concussion with symptoms but without formal support. OBJECTIVE: To examine concussion symptoms and temporary academic accommodations during school use of a four-week student-centered return to learn (RTL) care plan. METHODS: Five public high schools used the RTL care plan and contributed student-level data after student report of concussion. Data on concussion symptoms, temporary academic accommodations corresponding to reported symptoms, and accommodations provided during RTL care plan use were examined. RESULTS: Of 115 students, 55%used the RTL care plan for three (34%) or four (21%) weeks. Compared to students whose symptoms resolve within the first two weeks, students who used the RTL care plan for three or four weeks reported more unique symptoms (P = 0.038), higher total severity score (P = 0.005), and higher average severity per symptom (P = 0.007) at week one. Overall, 1,127 weekly accommodations were provided. While least reported, emotional symptoms received corresponding accommodations most often (127/155 reports: 82%of occurrences). CONCLUSIONS: Use of an RTL care plan can facilitate the RTL of students with a concussion and may aid in the identification of students who are in need of longer-term support.

Murder-Suicides Perpetrated by Adolescents: Findings from the National Violent Death Reporting System.

OBJECTIVE: Murder-suicide is a rare and especially tragic form of violence. Nascent literature has characterized murder-suicide perpetrated by adults, but no study has focused on adolescents who perpetrated murder-suicide. METHOD: This study evaluated all cases of murder-suicide perpetrated by persons under age 21 who were included in the National Violent Death Reporting System, and categorized each incident using Joiner's perversion of virtue framework of murder-suicide. RESULTS: Forty-seven incidents of murder-suicide perpetrated by adolescents were identified, representing 56 victims. Most cases did not have sufficient information to be categorized within a particular perversion of virtue. Among the 20 cases who did have sufficient detail to be categorized, incidents were identified as perversions of self-control (n = 11), justice (n = 8), and mercy (n = 1). Most perpetrators were male, and the majority of victims were female. Additional victim, perpetrator, and incident characteristics are described. CONCLUSIONS: Our findings extend previous work by employing a coding system based on a theoretically derived framework for categorizing "genuine" murder-suicide and related behavior among adolescents. This study also characterized the nature of this complex and tragic sequence of behavior among adolescents, who are at elevated risk of suicide, and who may benefit from prevention efforts that effectively address means safety, suicidality, and intimate partner violence.

Strategies to Address Unmet Needs and Facilitate Return to Learn Guideline Adoption Following Concussion.

BACKGROUND: Many students do not receive return to learn (RTL) services upon return to academics following a concussion. METHODS: Using a mixed-methods approach, we conducted a survey of RTL practices and experiences in Washington State schools between January 2015 and June 2015. We then held a statewide summit of RTL stakeholders and used a modified Delphi process to develop a consensus-based RTL implementation model and process. RESULTS: Survey participants included 83 educators, 57 school nurses, 14 administrators, and 30 parents, representing 144 schools in rural and urban areas. Unmet need domains and recommendations identified were (1) a current lack of school policies; (2) barriers to providing or receiving accommodations; (3) wide variability in communication patterns; and (4) recommendations shared by all stakeholder groups (including desire for readily available best practices, development of a formal school RTL policy for easy adoption and more training). Using stakeholder input from RTL summit participants and survey responses, we developed an RTL implementation model and checklist for RTL guideline adoption. CONCLUSIONS: Washington State children have unmet needs upon returning to public schools after concussion. The student-centered RTL model and checklist for implementing RTL guidelines can help schools provide timely RTL services following concussion.
