Childhood opportunity and appropriate use of child safety restraints in motor vehicle collisions

ObjectivesSafety restraints reduce injuries from motor vehicle collisions (MVCs) but are often improperly applied or not used. The Childhood Opportunity Index (COI) reflects social determinants of health and its study...

Child safety restraint patterns in Moldova

Objective The Republic of Moldova has one of the European region’s highest road traffic injury rates and also has an increase in motorization and exposure of children as vehicle passengers. This study describes child restraint use, and parents’ knowledge and attitudes toward child restraint based on observations in Chisinau, the country’s capital and largest city. The study aims to describe the use of child restraints and to compare data with existing standards of good practice. Methods An observational study on child safety restraint use was conducted in 2018. Observational sites included 22 early education institutions, where drivers (n = 611) and child passengers (n = 710) were observed. Observations were conducted as motor vehicles parked or pulled to a stop near the early education institutions and included a driver survey on knowledge and attitudes toward restraint legislation and child safety behavior. Results Of the 710 child passengers observed, 462 (65.1%) were appropriately restrained, 145 (20.4%) were seated in restraints inappropriate for the child and 103 (14.5%) of children were unrestrained. Younger children (0-3 year-old) were 7 times more likely to be properly restrained compared with children with ages between 4 and 6 (OR 1.92, 95% CI 1.15 to 3.22). Two-thirds out of 609 observed drivers with full study data, N = 431 (70,8%), knew about the mandatory legislation on using child safety restraints in the Republic of Moldova. The drivers using child safety restraints responded that they used them because of their safety features, and the major reason for nonuse was high price/affordability. Conclusion This study, the first to document child safety restraint use among children, indicates that much progress has been made, in that the majority of children are restrained and most drivers of children are aware of safety policies. However, progress can be made to increase knowledge and motivation to safely transport children, and to ensure safety seats are affordable and available. These data will be an important foundation on which to advocate for increased safety activities, child restraint policies, educational approaches in Moldova and to monitor progress over time.

COVID-19 severity and age increase the odds of delirium in hospitalized adults with confirmed SARS-CoV-2 infection: a cohort study

BackgroundDespite recognition of the neurologic and psychiatric complications associated with SARS-CoV-2 infection, the relationship between coronavirus disease 19 (COVID-19) severity on hospital admission and delirium in hospitalized patients is poorly understood. This study sought to measure the association between COVID-19 severity and presence of delirium in both intensive care unit (ICU) and acute care patients by leveraging an existing hospital-wide systematic delirium screening protocol. The secondary analyses included measuring the association between age and presence of delirium, as well as the association between delirium and safety attendant use, restraint use, discharge home, and length of stay.MethodsIn this single center retrospective cohort study, we obtained electronic medical record (EMR) data using the institutional Epic Clarity database to identify all adults diagnosed with COVID-19 and hospitalized for at least 48-h from February 1-July 15, 2020. COVID-19 severity was classified into four groups. These EMR data include twice-daily delirium screenings of all patients using the Nursing Delirium Screening Scale (non-ICU) or CAM-ICU (ICU) per existing hospital-wide protocols.ResultsA total of 99 patients were diagnosed with COVID-19, of whom 44 patients required ICU care and 17 met criteria for severe disease within 24-h of admission. Forty-three patients (43%) met criteria for delirium at any point in their hospitalization. Of patients with delirium, 24 (56%) were 65 years old or younger. After adjustment, patients meeting criteria for the two highest COVID-19 severity groups within 24-h of admission had 7.2 times the odds of having delirium compared to those in the lowest category [adjusted odds ratio (aOR) 7.2; 95% confidence interval (CI) 1.9, 27.4; P = 0.003]. Patients > 65 years old had increased odds of delirium compared to those < 45 years old (aOR 8.7; 95% CI 2.2, 33.5; P = 0.003). Delirium was associated with increased odds of safety attendant use (aOR 4.5; 95% CI 1.0, 20.7; P = 0.050), decreased odds of discharge home (aOR 0.2; 95% CI 0.06, 0.6; P = 0.005), and increased length of stay (aOR 7.5; 95% CI 2.0, 13; P = 0.008).ConclusionsWhile delirium is common in hospitalized patients of all ages with COVID-19, it is especially common in those with severe disease on hospital admission and those who are older. Patients with COVID-19 and delirium, compared to COVID-19 without delirium, are more likely to require safety attendants during hospitalization, less likely to be discharged home, and have a longer length of stay. Individuals with COVID-19, including younger patients, represent an important population to target for delirium screening and management as delirium is associated with important differences in both clinical care and disposition.

Trends in pediatric passenger restraint use by rurality and age in Iowa, 2006–2019

Objective Pediatric restraint use has increased over time in the United States, but motor vehicle crashes remain a leading cause of death for children under age 18. Age-appropriate use of safety restraints (safety seats, booster seats, seat belt) and statewide child restraint laws can greatly reduce injury or death in the event of a crash. Surveillance of pediatric restraint use and compliance with policy can inform prevention efforts. This study aims to examine time trends in pediatric restraint use and compliance with pediatric passenger laws in Iowa by rurality and age. Methods Fourteen years of Iowa observational pediatric restraint use data (2006–2019) are included in this cross-sectional study. Proportions of restrained youth by year, age, and rurality (rural, urban) were calculated. Log-linear models were used to compute the Annual Percent Change (APC) by year to explore trends in restraint use over time by rurality and by age group. Results A total of 42,007 observed pediatric passengers with complete data from 2006 to 2019 were included in this study. Restraint use increased across all years and all age groups observed, with the largest increases among the older pediatric age groups. However, restraint use was consistently highest among the youngest child passengers. With all study years combined, the odds of being compliantly restrained were 13% lower in rural areas (OR = 0.87, 95% CI = 0.80, 0.95) compared to urban areas. Conclusions Restraint use was lower in rural areas and among older pediatric passengers, suggesting targeted efforts to increase restraint use among these groups may have the greatest impact on overall occupant protection.

Outcomes Following Implementation of a Hospital-Wide, Multicomponent Delirium Care Pathway.

Delirium is associated with poor clinical outcomes that could be improved with targeted interventions. To determine whether a multicomponent delirium care pathway implemented across seven specialty nonintensive care units is associated with reduced hospital length of stay (LOS). Secondary objectives were reductions in total direct cost, odds of 30-day hospital readmission, and rates of safety attendant and restraint use. This retrospective cohort study included 22,708 hospitalized patients (11,018 preintervention) aged ≥50 years encompassing seven nonintensive care units: neurosciences, medicine, cardiology, general and specialty surgery, hematology-oncology, and transplant. The multicomponent delirium care pathway included a nurse-administered delirium risk assessment at admission, nurse-administered delirium screening scale every shift, and a multicomponent delirium intervention. The primary study outcome was LOS for all units combined and the medicine unit separately. Secondary outcomes included total direct cost, odds of 30-day hospital readmission, and rates of safety attendant and restraint use. Adjusted mean LOS for all units combined decreased by 2% post intervention (proportional change, 0.98; 95% CI, 0.96-0.99; P = .0087). Medicine unit adjusted LOS decreased by 9% (proportional change, 0.91; 95% CI, 0.83-0.99; P = .028). For all units combined, adjusted odds of 30-day readmission decreased by 14% (odds ratio [OR], 0.86; 95% CI, 0.80-0.93; P = .0002). Medicine unit adjusted cost decreased by 7% (proportional change, 0.93; 95% CI, 0.89-0.96; P = .0002). This multicomponent hospital-wide delirium care pathway intervention is associated with reduced hospital LOS, especially for patients on the medicine unit. Odds of 30-day readmission decreased throughout the entire cohort.

Pediatric Safety Restraint Use in Motor Vehicle Crashes at a Level I Safety-Net Trauma Center

BackgroundAdherence to child passenger safety recommendations is essential to prevent death and injury in children involved in motor vehicle crashes. Parents may not undertake the proper safety measures, which can lead to increase injury. MethodsA safety net, level I trauma center's database was used to identify admitted children (age<15 y/o) involved in motor vehicle crashes over a 2-y period to investigate safety restraint device use and compliance with state recommendations. Variables evaluated were crash characteristics, presence and method of passenger restraint, demographics, Glasgow Coma Scale, and Injury Severity Score. Excluded were patients where restraint characteristics could not be identified and those discharged from the trauma center. ResultsEighty patients met inclusion criteria. Thirty-two (40%) children were unrestrained. Safety restraint device was noted in 48 (60%) children with 13 (27.1%) patients improperly restrained. The most common method of improper restraint (6, 46.2%) was traveling in the front seat before the age state law recommends. With respect to proper, improper, and no restraint, age (7.31 ± 14.26, 5.76 ± 3.24, P = 0.36), female sex (17, 8, 13, P = 0.32), low-income status (14, 5, 24, P = 0.28), and race (P = 0.08) did not differ between the groups. The unrestrained children had statistically lower initial Glasgow Coma Scale and higher Injury Severity Score and were more often involved in high-risk mechanism of Injury motor vehicle crashes. ConclusionsDespite recommendations and regulations regarding child passenger safety measures, there are a significant number of children that remain suboptimally restrained who are admitted to a safety-net trauma center. Further research is needed to understand the barriers to increase the compliance with recommendations along with targeted educational campaigns in low-compliance populations.

Teaching installation and use of child passenger safety restraints.

Correctly installed child passenger safety restraints may reduce the risk of child injury and death during accidents. The present study evaluated behavioral skills training and self-monitoring to teach correct installation and use of a child passenger safety restraint in the rear-facing position. Extension probes were conducted with untrained installations and harnessing positions. Training was successful in teaching participants all installation methods and harnessing positions.

The Impact of Child Safety Restraint Status and Age in Motor Vehicle Collisions in Predicting Type and Severity of Bone Fractures and Traumatic Injuries.

Although morbidity and mortality in children increases in motor vehicle collisions (MVC) if child restraints are not used, no data exist correlating specific injuries with proper or improper use of safety restraints or age. The purpose of this study was to evaluate correlations between childhood MVC injuries, age, and restraint status. A medical record search for pediatric patients involved in a MVC was conducted at a pediatric hospital (level 1 trauma). Charts were reviewed for demographics and injury-specific information. Patients were grouped by age, restraint use, and injuries. Nine hundred sixty-seven patients ≤12 years (average age 6.39 y) were identified. Being properly restrained was most common in all age groups except the 4- to 8-year age group in which being improperly restrained was most common. Unrestrained patients were most commonly found in the 9- to 12-year age group. A statistically significant difference was not observed for orthopaedic injuries among the restraint groups, but internal thoracic injuries, open head wound, and open upper extremity wounds were significantly more common in improperly or unrestrained patients. Improperly restrained infants had a significantly higher rate of intracranial bleeds and abrasions than those properly restrained. Unrestrained and improperly restrained 9- to 12-year olds had significantly more open head, open upper extremity, and vascular injuries. When comparing injury types with age groups, upper extremity fractures, femoral fractures, dislocations, and spinal fractures were found to be significantly higher in older children. Preventing orthopaedic injuries in older children may be accomplished by changes in regulations or automotive safety equipment. Rear-facing child safety seats could possibly be improved to prevent head trauma in the youngest patients. There is a continued need to reinforce the importance of proper use of child safety devices to parents. Knowledge of the patient's age, along with restraint status, might aid in diagnosis of less obvious MCV injuries. Level III.

A comparative analysis of child passenger restraint use in China and the United States.

Few published studies have examined child passenger safety practices across countries. This study compared the prevalence and associated factors of child passenger restraint use among children, aged 0 to 17 in the state of Iowa in the United States, and the city of Shantou in China. Child restraint use observations were conducted in Iowa and in Shantou in 2012, respectively, among child passengers. Observations in Iowa were conducted at randomly selected gas stations, while in Shantou observations were completed at randomly selected schools or medical clinics. Research observers approached the driver, observed restraint use, and collected brief survey data. A total of 3049 children from Iowa and 3333 children aged 0 to 17 years from Shantou were observed. For children aged 0 to 3 years, only 0.1% were compliantly restrained in Shantou as compared to 95.9% in Iowa. The proportion of children who were compliantly restrained in Shantou increased with age, but generally decreased with age in Iowa. In Shantou, 36.0% of children aged 0 to 3 were sitting in the front seat as compared to only 1.7% of children of the same age in Iowa. Driver seat belt use was significantly associated with child restraint in both Iowa and Shantou; the association was stronger in Iowa than Shantou for all age groups. A significantly higher prevalence of children who were not appropriately restrained was observed in Shantou than in Iowa. Our findings support the need of mandatory child safety restraint use legislation in China.

Evaluation of a participative education process for increasing tween restraint use in Virginia: The Make it Click initiative

IntroductionNearly half of 8–12year-old tweens killed in car crashes every year in the US are completely unrestrained, and the majority sit in the front seat. The purpose of this study was to develop and evaluate a school-based program targeting increased safety restraint and back-seat use among tweens. Design and settingThe multi-component school-wide program was evaluated via a pre-post control-group design in four public elementary schools in an economically disadvantaged, multi-ethnic urban community in southeastern Virginia. Study schools had 1184 students enrolled in third through sixth grades. InterventionThe Make it Click Initiative was developed with input from student focus groups, surveys, and school personnel. Grounded in social cognitive theory and principles of behavioral psychology, the participative education program included: (a) competition to achieve a high rate of students buckled in the back; (b) a creativity contest with entries illustrating a car safety theme; (c) a series of parent education flyers; (d) car safety assignments that support state learning objectives; (e) a safety-themed play; (f) teacher newsletters; and (g) educational presentations. Main outcome measuresBehavioral observations (N=762) of children’s restraint and back seat use. ResultsMake it Click intervention schools’ observed safety belt use increased from 31.9% to 67.9%, and students in intervention schools were 3.3 times more likely to wear their belts at follow-up than students in control schools, X2(1)=19.72, p<0.001. Further, increases in belt use were maintained in study observations longer than those resulting from the highly publicized national Click it or Ticket enforcement program. Significant differences were not observed in back seat use. ConclusionsThe program resulted in significant improvements in observed safety belt use that outlasted results observed locally from the national high visibility enforcement program alone. Theory-driven participative education programs can improve the safety practices of school-age children.

Restraint Usage Characteristics and Other Factors Associated with Safety of Children Involved in Motor Vehicle Crashes

Involvement in road traffic crashes as vehicle occupants is a leading cause of death and serious injury among children. The objective of this study was to investigate crash severity factors and child safety restraint use characteristics in order to identify effective countermeasures to increase children's highway safety. Characteristics and percentages of restraint use among child passengers aged 4~13 years were examined using highway crash data from Kansas. The association between restraint use, injury severity and characteristics of children involved in crashes were investigated using OR (odds ratios) and a logistic regression model, which was used to identify risk factors. RESULTS showed that children, who were unrestrained, were seated in the front seat, traveling with drunk drivers and on rural roads, and traveling during nighttime was more vulnerable to severe injury in the case of motor vehicle crashes. The most frequent contributing causes related to crashes involving children included driver's inattention while driving, failure to yield right-of-way, driving too fast, wet roads and animals in the road. Based on identified critical factors, general countermeasure ideas to improve children's traffic safety were suggested, including age-appropriate and size-appropriate seat belt restraints and having children seated in the rear seat. Parents and children must gain better education regarding these safety measures in order to increase child safety on the road. Language: en

Child safety restraint usage in Romania - an observational study design

Background Romania presently has limited policies and capacity to prevent child and adolescent injuries but also little data to document the consequences of not using appropriate child passenger restraint. Our aim was to document child safety restraint use and identify factors associated with proper child restraint in a motor vehicle. Methods An observational study on child safety restraint was conducted in Cluj-Napoca, Romania, between 2013 and 2014. Observational sites included 38 schools and kindergartens …

Hospital-based program to increase child safety restraint use among birthing mothers in China.

ObjectiveTo evaluate a hospital-based educational program to increase child safety restraint knowledge and use among birthing mothers.MethodsA prospective experimental and control study was performed in the Obstetrics department of hospitals. A total of 216 new birthing mothers from two hospitals (114 from intervention hospital and 102 from comparison hospital) were recruited and enrolled in the study. Intervention mothers received a height chart, an 8-minute video and a folded pamphlet regarding child safety restraint use during their hospital stay after giving birth. Evaluation data on the child safety seat (CSS) awareness, attitudes, and use were collected among both groups before and after the intervention. An additional phone interview was conducted among the intervention mothers two months after discharge.ResultsNo significant differences existed between groups when comparing demographics. Over 90% of the intervention mothers found the educational intervention to be helpful to some extent. A significantly higher percentage of mothers in the intervention than the comparison group reported that CSS are necessary and are the safest seating practice. Nearly 20% of the intervention mothers actually purchased CSS for their babies after the intervention. While in both the intervention and comparison group, over 80% of mothers identified the ages of two through five as needing CSS, fewer than 50% of both groups identified infants as needing CSS, even after the intervention.ConclusionThe results indicated that child safety restraint education implemented in hospitals helps increase birthing mothers' overall knowledge and use of CSS. Further efforts are needed to address specific age-related needs to promote car seats use among infants.

Behavioral skills training to improve installation and use of child passenger safety restraints.

The risk for serious injury and death to children during motor vehicle accidents can be greatly reduced through the correct use of child passenger safety restraints (CPSRs). Unfortunately, most CPSRs are installed or used incorrectly. This study examined the effectiveness of behavioral skills training (BST) to teach 10 participants to install rear-facing CPSRs correctly using a multiple baseline design. Results show that installation errors were common for all participants during baseline. After BST, all 10 participants were able to install the rear-facing CPSR without error. An extension probe to assess whether the skills taught during BST extended to forward-facing installation showed that each participant made at least 1 critical error.

Parents’ experience with child safety restraint in China

BackgroundChild safety restraints are effective measures in protecting children from an injury while traveling in a car. However, the rate of child restraint use is extremely low in Chinese cities. Parent drivers could play an important role in promoting child safety restraint use, but not all of them take active responsibility.MethodsThis study used a qualitative approach and included 14 in-depth interviews among parents with a child, under the age of 6, living in Shantou City (7 child safety restraint users and 7 non-users). Purposive sampling was used to recruit eligible parent drivers who participated in a previous observation study. Interview data were collected from March to April 2013. The audio taped and transcribed data were coded and analyzed to identify key themes.ResultsFour key themes on child safety restraint emerged from the in-depth interviews with parents. These included 1) Having a child safety restraint installed in the rear seat with an adult sitting next to the restrained child is ideal, and child safety restraint is seen as an alternative when adult accompaniment is not available; 2) Having effective parental education strategies could help make a difference in child safety restraint use; 3) Inadequate promotion and parents’ poor safety awareness contribute to the low rate of child safety restraint in China; 4) Mandatory legislation on child safety restraint use could be an effective approach.ConclusionInadequate promotion and low awareness of safe traveling by parents were closely linked to low child safety seat usage under the circumstance of no mandatory legislation. Future intervention efforts need to focus on increasing parents’ safe travel awareness combined with CSS product promotion before the laws are enacted.

Pediatric and Youth Traffic-Collision Injuries in Al Ain, United Arab Emirates: A Prospective Study

AimTo study the mechanism of road traffic collisions (RTC), use of safety devices, and outcome of hospitalized pediatric and youth RTC injured patients so as to give recommendations regarding prevention of pediatric RTC injuries.MethodsAll RTC injured children and youth (0–19-year-olds) who were admitted to Al Ain City’s two major trauma centers or who died after arrival to these centers were prospectively studied from April 2006 to October 2007. Demography of patients, road-user and vehicle types, crash mechanism, usage of safety devices, injured body regions, injury severity, Revised Trauma Score, Glasgow Coma Scale, intensive care unit admissions, hospital stay and mortality were analyzed.Results245 patients were studied, 69% were vehicle occupants, 15% pedestrians, 9% motorcyclists and 5% bicyclists. 79% were males and 67% UAE citizens. The most common mechanism of RTC was rollover of vehicle (37%) followed by front impact collision (32%). 32 (13%) of vehicle occupants were ejected from car. 63% of ejected occupants and 70% of motorcyclists sustained head injuries. Only 2% (3/170) vehicle passengers used seatbelts and 13% (3/23) motorcyclists a helmet.ConclusionsMale drivers and UAE nationals were at high risk of RTC as drivers and as motorcyclists. Ejection rate was high because safety restraint use was extremely low in our community. More education and law enforcement focusing especially on car/booster seat use is needed.

Child and Youth Traffic-Related Injuries: Use of a Trauma Registry to Identify Priorities for Prevention in the United Arab Emirates

Objective: Traffic-related injuries are the main cause of death during childhood and youth in the United Arab Emirates (UAE), use of safety restraints by citizens is uncommon, rollovers are frequent, and current legislation does not protect rear-seat occupants. Because little was known about the circumstances of hospitalizations for traffic injuries to guide prevention, a trauma registry was used to assess causes and determinants for traffic-related injuries during childhood and youth (<19 years) and its value for prevention. Methods: One hundred ninety-three children and youth with traffic injuries were admitted for more than 24 h at surgical wards of the main trauma hospital in the Al-Ain region during a 36-month period (2003–2006). Injuries were analyzed by age, nationality, road user and vehicle types, severity, anatomical region, and the presence of head injury using Injury Severity Scores (ISS) and the Abbreviated Injury Scale (AIS). Results: Traffic injuries represented 40 percent (n = 193) of injuries to 0- to 19-year-olds, followed by falls (39 percent). Among 15- to 19-year-olds, who accounted for 46 percent of child and youth victims, the incidence was 150/100,000 person years, compared to an incidence of 15 to 51 for younger age groups. Overall, 53 percent were vehicle occupants, 23 percent were pedestrians, 14 percent were bicyclists, 6 percent were motorcyclists, with 4 percent other. The ratio of male-to-female victims was 6.7:1; for drivers it was 33:0; and for pedestrians, bicyclists, and motorcyclists it was between 10:1 and 12:1; injured females were mainly rear-seat passengers and the male: female ratio was 1.4:1. Seventy-one percent of pedestrians were ≤9 years old. Although the ratio of UAE children to foreign children was estimated at 0.7:1 in the community, 58 percent of the injured were UAE citizens. The ratio of injured UAE: non-UAE citizens was 1.4:1 overall but 5.6:1 for drivers and 4.5:1 for motorcyclists. Forty-one percent of citizens were injured in 4-wheel drive sport utility vehicles compared to 13 percent of non-citizens. Head injuries occurred in 68 percent of vehicle occupants and 51 percent of nonoccupants, with AIS ≥ 3 injuries in 23 percent of occupants and 26 percent of nonoccupants. Sixty-seven percent of rear occupants had head injuries. Conclusions: Male drivers and vulnerable road users were at an unusually high risk relative to females. A relatively high frequency of traffic-related head injuries among UAE children and youth, including rear-seat passengers and other vehicle occupants, suggests that considerable preventable morbidity is associated with nonuse of safety restraints and/or other factors such as excess speed and rollovers of 4-wheel drive vehicles. Trauma registries can be useful for prevention; inclusion of data on safety restraints and helmet use by road user type is essential.

I love my baby even unto death: child safety restraint use among drivers in Gaborone, Botswana

This study examined the use of child safety restraints by drivers transporting children in Gaborone, Botswana. We observed 518 vehicles (329 male drivers, 189 female drivers) carrying children at four different locations in Gaborone over four days. A team of 2-4 trained observers recorded whether the child was restrained or not, where they were seated in the car, the type of vehicle (private or commercial) and model of vehicle. Children were restrained in 111 (21.4%) of the observed vehicles and unrestrained in 407 (78.6%) of the observed vehicles. Additionally, male drivers were more likely than female drivers to have an unrestrained child (chi-square = 4.465, P=.04); commercial vehicles were more likely than private vehicles to have an unrestrained child (chi-square= 7.387, P=.01); SUVs were more likely to have a restrained child (chi-square = 17.499, P=.00); and children in the back seat of the vehicle were less likely to be restrained than children located in the front seat (chi-square = 49.036, P=.00). There was also a noted difference based on location (chi-square= 19.405, P=.00), indicating socioeconomic factors at play. Most drivers in Gaborone are not restraining children in vehicles. There seems to be a general lack of knowledge among drivers about the importance of child safety restraints. It is recommended that stakeholders work to raise awareness, enforce legislation and offer incentives and subsidies for car seat use in order to improve the safety of child passengers on Botswana’s expanding and developing roads.

Motor vehicle injuries among semi truck drivers and sleeper berth passengers

IntroductionInjuries and fatalities due to large truck and other vehicle crashes have decreased over the last decade, but motor vehicle injuries remain a leading cause of death for both the working and general populations. The present study was undertaken to determine semi truck driver and sleeper berth passenger injury risk in a moving semi truck collision using a matched-pair cohort study. MethodStudy data were obtained from the Kentucky Collision Report Analysis for Safer Highways (CRASH) electronic files for 2000–2010. A matched-pair cohort study was used to compare the odds of injury of both drivers and sleeper berth passengers within the same semi truck controlling for variables specific to the crash or the semi truck. The crude odds ratio of injury was estimated and a statistical model for a correlated outcome using generalized estimating equations was utilized. ResultsIn a moving semi truck collision, the odds for an injury were increased by 2.25 times for both semi truck drivers and sleeper berth passengers who did not use occupant safety restraints compared to semi truck drivers and sleeper berth passengers who used occupant safety restraints at the time of the collision. The driver seat or sleeper berth position in the vehicle was not a significant factor (p-value=0.31) associated with a moving semi truck collision injury. ConclusionNonuse of occupant safety restraints by either drivers or sleeper berth passengers significantly increased the odds of an injury in a moving semi truck collision; semi truck seating position (driver's seat or sleeper berth) did not increase the odds for an injury in moving collisions. Impact on IndustryTrucking companies should include the mandatory use of occupant safety restraints by both semi truck drivers and sleeper berth passengers in their company safety policies.
