Home safe home: Evaluation of a childhood home safety program.

BACKGROUND: The London Health Sciences Centre Home Safety Program (HSP) provides safety devices, education, a safety video, and home safety checklist to all first-time parents for the reduction of childhood home injuries. The objective of this study was to evaluate the HSP for the prevention of home injuries in children up to 2 years of age. METHODS: A program evaluation was performed with follow-up survey, along with an interrupted time series analysis of emergency department (ED) visits for home injuries 5 years before (2007-2013) and 2 years after (2013-2015) implementation. Spatial analysis of ED visits was undertaken to assess differences in home injury rates by dissemination areas controlling differences in socioeconomic status (i.e., income, education, and lone-parent status) at the neighborhood level. RESULTS: A total of 3,458 first-time parents participated in the HSP (a 74% compliance rate). Of these, 20% (n = 696) of parents responded to our questionnaire, with 94% reporting the program to be useful (median, 6; interquartile range, 2 on a 7-point Likert scale) and 81% learning new strategies for preventing home injuries. The median age of the respondent's babies were 12 months (interquartile range, 1). The home safety check list was used by 87% of respondents to identify hazards in their home, with 95% taking action to minimize the risk. The time series analysis demonstrated a significant decline in ED visits for home injuries in toddlers younger than2 years of age after HSP implementation. The declines in ED visits for home injuries remained significant over and above each socioeconomic status covariate. CONCLUSION: Removing hazards, supervision, and installing safety devices are key facilitators in the reduction of home injuries. Parents found the HSP useful to identify hazards, learn new strategies, build confidence, and provide safety products. Initial finding suggests that the program is effective in reducing home injuries in children up to 2 years of age. LEVEL OF EVIDENCE: Therapeutic/care management study, level V.

An evidence-based method for targeting an abusive head trauma prevention media campaign and its evaluation.

BACKGROUND: A triple-dose abusive head trauma (AHT) prevention program (Period of PURPLE Crying) was implemented. The third dose consisted of an education media campaign. The study objectives were to describe the qualitative and spatial methods developed to target AHT prevention and to evaluate this campaign. METHODS: A questionnaire on the level of importance of factors, rated on a 7-point Likert scale, was distributed to a panel of experts to determine the best advertising locations. Ranked factors were used to create weights for statistical modeling and mapping within a Geographic Information Systems to determine optimal ad locations. The media campaign was evaluated via a telephone survey of randomly selected households. RESULTS: The survey found locations of new families, high population density, and high percentage of lone parents to be the most important factors for selecting billboard sites. Spatial analysis revealed six areas that ranked highest in our factors. Five billboards, four media posters, and six transit shelters were selected for our advertisements. A population-based telephone survey revealed that 23% of respondents knew the campaign. Nearly half (42%) heard the radio public service announcements, and 9% saw billboards. CONCLUSION: Extending primary prevention efforts to the public helps to create a cultural change in the way inconsolable crying, the trigger for AHT, is viewed. With the use of ranked factors and Geographic Information Systems, geographic locations with high visibility and specific risk factors for AHT were identified for targeting the campaign, facilitating the likelihood that our message was reaching the population in greatest need.

From focus groups to production of a distracted driving video: Using teen input to drive injury prevention programming.

BACKGROUND: The Impact program is an adolescent, injury prevention program with both school- and hospital-based components aimed at decreasing high-risk behaviors and preventing injury. The objective of this study was to obtain student input on the school-based component of Impact, as part of the program evaluation and redesign process, to ensure that the program content and format were optimal and relevant, addressing injury-related issues important for youth in our region. METHODS: Secondary schools were selected in various geographic regions with students varying in language, religion, and socioeconomic status. A mixed-methods questionnaire was developed and pretested on program content, format, relevance, quality, and effectiveness. Attitude and opinion questions on issues facing teens today were ranked on a 7-point Likert scale. Open-ended, qualitative questions were included in the focus groups, with responses themed. RESULTS: There were 167 respondents in the nine geographically, socioeconomically, and culturally diverse focus groups with a mean age of 16 years, 52% were male, and 69% were in Grade 11. Ninety-three percent of respondents rated the content of Impact as comprehensive (median, 6 of 7, with 7 being very comprehensive), and 29% rated the format a 5 of 7. Impact was rated relevant (89%), addressing issues for teens (median, 6 of 7). Issues suggested to highlight included texting and driving, drugs, partying, self-harm, and abusive relationships. Texting while driving was perceived as a significantly more common (81%) injury issue for adolescents compared with other driving risk factors (p < 0.001), with one student commenting, "If you don't (text and drive), you either don't have a phone or don't have a driver's license." CONCLUSION: Injury prevention programs must be continually evaluated to ensure they are relevant, addressing issues important for youth, and presented in a format that resonates with the audience. Student focus groups identified motor vehicle collisions and texting as important issues as well as a desire for teens to hear personal stories with a visual element. This provided the information needed to develop the next logical direction for our program, the production of a distracted driving video ("Distracted Driving: Josh's Story," http://youtu.be/BFPke9gBybc) to be incorporated into school presentations.

Basal skull fractures are associated with mortality in pediatric severe traumatic brain injury.

BACKGROUND: Basal skull fractures (BSFs) are caused by blunt force trauma, occurring in the temporal, occipital, sphenoid, and/or ethmoid bones. In pediatric severe traumatic brain injury (sTBI), there is a paucity of data on BSFs. Our goal was to investigate the BSF prevalence, anatomy, and association with short-term outcomes in pediatric sTBI. METHODS: We retrospectively reviewed all severely injured (Injury Severity Score ≥12) pediatric patients (aged <18 years) admitted to our hospital after experiencing an sTBI (Glasgow Coma Scale score ≤8 and head Abbreviated Injury Scale score ≥4). Neuroimaging for all sTBI patients was reviewed for skull fractures. Data were analyzed with both univariate and multivariate techniques. RESULTS: Of the 180 patients with sTBI, 47 had BSFs for a prevalence of 26% (69 BSFs in total; 16 sTBI patients had ≥2 BSFs). The squamous temporal bone was fractured most frequently (n=30/47 sTBI patients with BSFs). Patients with BSFs were heavier and had more facial injuries than those without (p < 0.05) but were similar in all other admission demographics, injury profiles, and clinical characteristics. Cerebrospinal fluid leak was found in 32% (n = 15 of 47) of BSF patients (otorrhea, n = 12; rhinorrhea, n = 1; otorrhea/rhinorrhea, n = 2; p < 0.001). Mortality, acute central diabetes insipidus, and fewer ventilator-free days were associated with BSFs (p < 0.005), whereas in sTBI survivors, BSFs were associated with longer lengths of stay (p < 0.05). Multiple logistic regression showed that BSFs were positively associated with the presence of subarachnoid hemorrhage (odds ratio [OR], 4.00; p = 0.001), contusion (OR, 2.48; p = 0.029), herniation (OR, 3.40; p = 0.037), and cerebral edema (OR, 2.30; p = 0.047) but negatively associated with diffuse axonal injury (OR, 0.20; p = 0.003). BSFs and mortality were strongly associated (OR, 6.87; p = 0.019). CONCLUSION: BSFs occurred in 26% of pediatric sTBI patients. The temporal bone was fractured in two thirds of sTBI patients with BSFs, and one third was associated with cerebrospinal fluid leaks. BSFs represent a significant linear blunt force and are independent predictors of mortality. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III.

An epidemiologic profile of pediatric concussions: identifying urban and rural differences.

BACKGROUND: The objective of this study was to describe the epidemiology of concussions presenting to the emergency department (ED). METHODS: A retrospective cohort of concussions for pediatric (age < 18 years) patients treated in the ED of a regional pediatric Level 1 trauma center from 2006 to 2011 was examined. Descriptive and geographic analyses were completed, with comparisons by age groups and residence (urban/rural). RESULTS: There were a total of 2,112 treated pediatric concussions. Two thirds of the concussions occurred in males (67%), with a median age of 13 years (interquartile range [IQR], 6). Nearly half of the pediatric concussions were sports related (48%); 36% of these concussions were from hockey. Significant differences were found in the distribution of the mechanism of injury across age groups (p < 0.001). Falls were most prevalent among young children, and sports concussions, for children 10 years and older. Two fifths of concussions occurred during winter months. Discharge disposition significantly differed by age (p < 0.001), with home discharge increasing with age up to 14 years. There were a total of 387 rural (19%) and 1,687 urban (81%) concussed patients, for a mean ED concussion visit rate of 2.2 per 1,000 and 3.5 per 1,000, respectively. Rural patients were older (14 [IQR, 6] vs. 13 [IQR, 6], p = 0.019] and sustained 2.5 times more concussions from a motor vehicle crash compared with urban youth patients (p < 0.001). CONCLUSION: Males in early adolescence are at highest risk for concussion, particularly from sport-related activities. Urban and rural children have differences in their etiology and severity of concussions. Concussions are predictable, and their prevention should be targeted based on epidemiologic and environmental data. LEVEL OF EVIDENCE: Epidemiologic, study, level III.

The role of serious concomitant injuries in the treatment and outcome of pediatric severe traumatic brain injury.

BACKGROUND: The study objective was to describe the epidemiology of serious concomitant injuries and their effects on outcome in pediatric severe traumatic brain injury (sTBI). METHODS: A retrospective cohort of all severely injured (Injury Severity Score [ISS] ≥ 12) pediatric patients (<18 years) admitted to our pediatric intensive care unit, between 2000 and 2011, after experiencing an sTBI (Glasgow Coma Scale [GCS] score ≤ 8 and head Abbreviated Injury Scale [AIS] ≥ 4) were included. Two groups were compared based on the presence of serious concomitant injuries (maximum AIS score ≥ 3). Multivariate logistic regression was undertaken to determine variable associations with mortality. RESULTS: Of the 180 patients with sTBI, 113 (63%) sustained serious concomitant injuries. Chest was the most commonly injured extracranial body region (84%), with lung being the most often injured. Patients with serious concomitant injuries had increased age, weight, and injury severity (p < 0.001) and were more likely injured in a motor vehicle collision (91% vs. 48%, p < 0.001). Those with serious concomitant injuries had worse sTBI, based on lower presedation GCS (p = 0.031), higher frequency of fixed pupils (p = 0.006), and increased imaging abnormalities (SAH and DAI, p ≤ 0.01). Non-neurosurgical operations and blood transfusions were more frequent in the serious concomitant injury group (p < 0.01). The differences in mortality for the two groups failed to reach statistical significant (p = 0.053), but patients with serious concomitant injuries had higher rates of infection and acute central diabetes insipidus, fewer ventilator-free days, and greater length of stays (p < 0.05). Multivariate analyses revealed fixed pupillary response (odd ratio [OR], 63.58; p < 0.001), presedation motor GCS (OR, 0.23; p = 0.001), blood transfusion (OR, 5.80; p = 0.008), and hypotension (OR, 4.82; p = 0.025) were associated with mortality, but serious concomitant injuries was not (p = 0.283). CONCLUSION: Head injury is the most important prognostic factor in mortality for sTBI pediatric patients, but the presence of serious concomitant injuries does contribute to greater morbidity, including longer stays, more infections, fewer ventilator-free days, and a higher level of care required on discharge from hospital.
