BACKGROUND: Systemic inequities may place people with disabilities at higher risk of severe COVID-19 illness or lower likelihood to be discharged home after hospitalization. We examined whether severity of COVID-19 hospitalization outcomes and disposition differ by disability status and disability type. METHODS: In a retrospective analysis of April 2020-November 2021 hospital-based administrative data among 745,375 people hospitalized with COVID-19 from 866 US hospitals, people with disabilities (n = 120,360) were identified via ICD-10-CM codes. Outcomes compared by disability status included intensive care admission, invasive mechanical ventilation (IMV), in-hospital mortality, 30-day readmission, length of stay, and disposition (discharge to home, long-term care facility (LTCF), or skilled nursing facility (SNF). RESULTS: People with disabilities had increased risks of IMV (aRR: 1.05; 95%CI: 1.03-1.08) and in-hospital mortality (1.04; 1.02-1.06) compared to those with no disability; risks were higher among people with intellectual and developmental disabilities (IDD) (IMV [1.34; 1.28-1.40], mortality [1.31; 1.26-1.37]) or mobility disabilities (IMV [1.13; 1.09-1.16], mortality [1.04; 1.01-1.07]). Risk of readmission was increased among people with any disability (1.23; 1.20-1.27) and each disability type. Risks of discharge to a LTCF (1.45, 1.39-1.49) or SNF (1.78, 1.74-1.81) were increased among community-dwelling people with each disability type. CONCLUSIONS: Severity of COVID-19 hospitalization outcomes vary by disability status and type; IDD and mobility disabilities were associated with higher risks of severe outcomes. Disparities such as differences in discharge disposition by disability status require further study which would be facilitated by standardized data on disability. Increased readmission across disability types indicates a need to improve discharge planning and support services.

Mild traumatic brain injury (mTBI) or concussion, once thought to be a fairly benign injury with little or no long-term consequences, has been recognized as an important public health concern among children and adolescents. From 2005 to 2009, an estimated 3 million children were seen in emergency departments, and an additional 2 million were seen as outpatients for treatment of mTBI.1 Children with mTBI may experience symptoms that affect cognitive, physical, and psychological function.2 For most children with mTBI, symptoms resolve within 2 to 4 weeks; however, a subset of children will continue to experience symptoms for 3 or more months.3

Chronic pain is recognized by the National Academy of Medicine (formerly Institute of Medicine) as a highly prevalent disease occurring much more frequently than other chronic diseases that are widely accepted as public health priorities.1 In fact, the overall prevalence of chronic pain is estimated to be higher than that of diabetes, cardiovascular disease, and cancer combined.1 As the largest subset of chronic pain conditions, musculoskeletal pain is a common reason to seek health care1 and is a leading cause of disability globally due to back, neck, and/or joint pain.2

Objectives: To assess the distribution of injury mechanisms and activities among children with concussions in a large pediatric healthcare system. Study design: All patients, age 0-17 years, who had at least 1 clinical encounter with an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis of concussion in the Children's Hospital of Philadelphia's electronic health record system from July 1, 2012 to June 30, 2014, were selected (N = 8233) and their initial concussion-related visit identified. Approximately, 20% of the patients (n = 1625) were randomly selected for manual record review to examine injury mechanisms and activities. Results: Overall, 70% of concussions were sports related; however, this proportion varied by age. Only 18% of concussions sustained by children aged 0-4 were sports related, compared with greater proportions for older children (67% for age 5-11, 77% for age 12-14, and 73% for age 15-17). When the concussion was not sports related, the primary mechanisms of injury were struck by an object (30%) and falls (30%). Conclusions: Sports-related injuries in children older than 6 years of age contributed to the majority of concussions in this cohort; however, it is important to note that approximately one-third of concussions were from non–sports-related activities. Although there is increased participation in community and organized sports activities among children, a focus on prevention efforts in other activities where concussions occur is needed.

OBJECTIVE: To describe similarities and differences in the number of civilian traumatic brain injury (TBI)-related hospitalizations and emergency department visits between national databases that capture US hospital data. PARTICIPANTS: TBI-related hospitalizations included in the National Hospital Discharge Survey (NHDS) and Healthcare Cost and Utilization Project Nationwide Inpatient Sample (HCUP-NIS) and emergency department visits in the National Hospital Ambulatory Medical Care Survey (NHAMCS) and HCUP Nationwide Emergency Department Sample (HCUP-NEDS) for 2006-2010. DESIGN: Cross-sectional design. MAIN MEASURES: Nationwide counts of TBI-related medical encounters. RESULTS: Overall, the frequency of TBI is comparable when comparing NHDS with HCUP-NIS and NHAMCS with HCUP-NEDS. However, annual counts in both NHDS and NHAMCS are consistently unstable when examined in smaller subgroups, such as by age group and injury mechanism. Injury mechanism is consistently missing from many more records in NHDS compared with HCUP-NIS. CONCLUSION: Given the large sample size of HCUP-NIS and HCUP-NEDS, these data can offer a valuable resource for examining TBI-related hospitalization and emergency department visits, especially by subgroup. These data hold promise for future examinations of annual TBI counts, but ongoing comparisons with national probability samples will be necessary to ensure that HCUP continues to track with estimates from these data.

In the first three decades of life, more individuals in the USA die from injuries and violence than from any other cause. Millions more people survive and are left with physical, emotional, and financial problems. Injuries and violence are not accidents; they are preventable. Prevention has a strong scientific foundation, yet efforts are not fully implemented or integrated into clinical and community settings. In this Series paper, we review the burden of injuries and violence in the USA, note effective interventions, and discuss methods to bring interventions into practice. Alliances between the public health community and medical care organisations, health-care providers, states, and communities can reduce injuries and violence. We encourage partnerships between medical and public health communities to consistently frame injuries and violence as preventable, identify evidence-based interventions, provide scientific information to decision makers, and strengthen the capacity of an integrated health system to prevent injuries and violence.

BACKGROUND: The Checkpoints program (Checkpoints) uses a Parent-Teen Driving Agreement (PTDA) to help parents monitor teens' driving, and has shown efficacy in increasing parental restrictions on teens' driving and decreasing teens' risky driving. In previous trials, research staff administered Checkpoints. This study examined the effectiveness of Checkpoints when delivered by driver educators. It was hypothesized that Checkpoints would result in more PTDA use, greater PTDA limits on higher risk driving situations, and less high-risk driving. METHODS: Eight trained driving instructors were randomly assigned to intervention or control groups in a group randomized trial. Instructors enrolled 148 parent-teen dyads (intervention = 99, control = 49); 35% of those eligible. Intervention parents joined teens for a 30-minute Checkpoints session during driver education. The session included a video, persuasive messages, discussion, and PTDA initiation. Teens completed four surveys: baseline, licensure, and 3- and 6-months post-licensure. RESULTS: Intervention teens were more likely to report that they used a PTDA (OR= 15.92, p = .004) and had restrictions on driving with teen passengers (OR = 8.52, p = .009), on weekend nights (OR = 8.71, p = .021), on high-speed roads (OR = 3.56, p = .02), and in bad weather (b = .51, p = .05) during the first six months of licensure. There were no differences in offenses or crashes at six months, but intervention teens reported less high-risk driving (p = .04). CONCLUSIONS: Although challenges remain to encourage greater parent participation, Checkpoints conducted by driver education instructors resulted in more use of PTDAs, greater restrictions on high-risk driving, and less high-risk driving. Including Checkpoints in driver education parent meetings/classes has potential to enhance teen driver safety.

The establishment of the National Center for Injury Prevention and Control (NCIPC or Injury Center) in 1992 as part of the Centers for Disease Control and Prevention (CDC) firmly established the Injury Center as the lead federal agency for non-occupational injury prevention and control (Sleet et al., 2012). Since then, it has provided leadership and a strong scientific base for intramural and extramural-investigator funded injury research. The Injury Center's scientific mission encompasses efforts from primary prevention to treatment and rehabilitation. Early CDC efforts were primarily focused on describing the extent of the problem, identifying risk and protective factors that affect the extent of violence and injury in our society, and gaining visibility for violence and injury as a major public health problem. Efforts such as the development of injury-based surveillance systems provided population-based surveillance data regarding the extent and distribution of fatal and non-fatal injuries, helped to identify demographic characteristics for those who were most at risk, and identified risk and protective factors that influence that risk. Celebrating the Injury Center's 20th anniversary presents an opportunity not only to reflect on past accomplishments but also to look ahead at what still needs to be done.

INTRODUCTION: The purpose of this study was to calculate national estimates and examine the extent to which children prematurely use adult seat belts and ride in the front seat of a vehicle during a 30 day period. METHODS: Data were obtained from a nationally representative cross-sectional random-digit-dial telephone survey that included child-specific questions on motor vehicle restraint use and seating position. RESULTS: Among children less than 13 years, parents reported an estimated 618,337 who rode unrestrained and more than one million who rode in the front seat of a vehicle at least some of the time in the past 30 days. During the same time period, close to 11 million children 8 years and younger reportedly used only adult seat belts. DISCUSSION: Our results highlight the need for continued outreach to parents regarding optimal restraint use and rear seating position for children every trip, every time.

OBJECTIVES: To characterize nonfatal, unintentional, fall-related injuries associated with walkers and canes in older adults. DESIGN: Surveillance data of injuries treated in hospital emergency departments (EDs), January 1, 2001, to December 31, 2006. SETTING: The National Electronic Injury Surveillance System All Injury Program, which collects data from a nationally representative stratified probability sample of 66 U.S. hospital EDs. PARTICIPANTS: People aged 65 and older treated in EDs for 3,932 nonfatal unintentional fall injuries and whose records indicated that a cane or a walker was involved in the fall. MEASUREMENTS: Sex, age, whether the fall involved a cane or walker, primary diagnosis, part of the body injured, disposition, and location and circumstances of the fall. RESULTS: An estimated 47,312 older adult fall injuries associated with walking aids were treated annually in U.S. EDs: 87.3% with walkers, 12.3% with canes, and 0.4% with both. Walkers were associated with seven times as many injuries as canes. Women's injury rates exceeded those for men (rate ratios=2.6 for walkers, 1.4 for canes.) The most prevalent injuries were fractures and contusions or abrasions. Approximately one-third of subjects were hospitalized for their injuries. CONCLUSION: Injuries and hospital admissions for falls associated with walking aids were frequent in this highly vulnerable population. The results suggest that more research is needed to improve the design of walking aids. More information also is needed about the circumstances preceding falls, both to better understand the contributing fall risk factors and to develop specific and effective fall prevention strategies.

OBJECTIVE: To demonstrate the effect of including both principal and secondary injuries in the calculation of national estimates of non-fatal motor vehicle-related injury, using the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP). METHODS: The setting was a stratified sample of 15 US hospital emergency departments selected among 50 NEISS-AIP hospitals which agreed to participate in the study. Non-fatal injury data from a special study of the 2004 NEISS-AIP were analysed which allowed up to five injuries to be coded per case. National estimates of number and rate of injuries for 2004 were calculated, first using principal injuries alone, then by including principal and secondary injuries. RESULTS: An estimated 4,833,626 principal and secondary injuries were sustained by the estimated 2,893,782 motor vehicle occupants involved in a crash and treated in US hospital emergency departments (EDs) in 2004. This represents a 67% increase in the total number of injuries compared with an estimate of principal injury alone. Incidence of contusions/abrasions and lower trunk injuries rose most steeply among broad injury types, and whiplash injury rose 18% in number and rate. A significantly lower percentage of cases with a single listed injury were hospitalised (5%) compared with those who sustained multiple injuries (8%). CONCLUSIONS: Based on an analysis of NEISS-AIP special study data, the inclusion of both principal and secondary injuries in national estimates of motor vehicle-related occupant injury would provide a more comprehensive report of non-fatal injuries treated in US hospital EDs. Other countries with ED-based surveillance systems could consider reporting multiple injuries when assessing injury count associated with motor vehicle trauma requiring ED care.
