Pilot Evaluation of the Family Bridge Program: A Communication- and Culture-Focused Inpatient Patient Navigation Program.

OBJECTIVE: Children with low income and minority race and ethnicity have worse hospital outcomes due partly to systemic and interpersonal racism causing communication and system barriers. We tested the feasibility and acceptability of a novel inpatient communication-focused navigation program. METHODS: Multilingual design workshops with parents, providers, and staff created the Family Bridge Program. Delivered by a trained navigator, it included 1) hospital orientation; 2) social needs screening and response; 3) communication preference assessment; 4) communication coaching; 5) emotional support; and 6) a post-discharge phone call. We enrolled families of hospitalized children with public or no insurance, minority race or ethnicity, and preferred language of English, Spanish, or Somali in a single-arm trial. We surveyed parents at enrollment and 2 to 4 weeks post-discharge, and providers 2 to 3 days post-discharge. Survey measures were analyzed with paired t tests. RESULTS: Of 60 families enrolled, 57 (95%) completed the follow-up survey. Most parents were born outside the United States (60%) with a high school degree or less (60%). Also, 63% preferred English, 33% Spanish, and 3% Somali. The program was feasible: families received an average of 5.3 of 6 components; all received >2. Most caregivers (92%) and providers (81% [30/37]) were "very satisfied." Parent-reported system navigation improved from enrollment to follow-up (+8.2 [95% confidence interval 2.9, 13.6], P = .003; scale 0-100). Spanish-speaking parents reported decreased skills-related barriers (-18.4 [95% confidence interval -1.8, -34.9], P = .03; scale 0-100). CONCLUSIONS: The Family Bridge Program was feasible, acceptable, and may have potential for overcoming barriers for hospitalized children at risk for disparities.

Driving characteristics of young adults prior to and following concussion.

OBJECTIVES: This study sought to examine whether young adults who sustain concussions have different driving histories and pre-injury driving styles than uninjured peers. In addition, we assessed whether modifications were made to driving behavior in the acute period following concussion. METHODS: Self-reported driving and demographic information was collected from 102 16- to 25-year-old drivers. Half of the sample had recently sustained concussions and the other half comprised a matched comparison group. RESULTS: The groups reported similar pre-injury driving behaviors and styles. However, the recently injured group had more driving citations, higher rates of psychiatric disorders, and greater likelihood of having sustained a prior concussion. Self-reported driving habits postconcussion suggested that most drivers did not modify their driving behavior following concussion, though they were less likely to drive at night or with others in the car. CONCLUSION: Results highlight the need for postconcussion driving guidelines and support for returning to driving safely.

Cognitive Impairment and Driving Skills in Youth After Concussion.

Abstract Concussions can impact cognitive processes necessary for driving. Young adults, a group who are more likely to engage in risky behaviors, have limited driving experience and a higher rate of motor vehicle collisions; they may be at higher risk for driving impairment after concussion. There are no clear guidelines for return-to-driving following a concussion. We sought to examine the simulated driving performance of young drivers after receiving medical care following a concussion, compared with a similar control population, to examine the association of driving performance with performance on neuropsychological tests. We evaluated 47 drivers, 16- to 25-year-old, within 3 weeks of sustaining a concussion and 50 drivers with similar characteristics who had not sustained concussions. Participants completed demographic questionnaires, the Sport Concussion Assessment Tool-5 (SCAT-5), and a brief set of neurocognitive tests, including the National Institutes of Health (NIH) Toolbox Cognition Battery and the Trail Making Test, and a simulated driving assessment. At various times during simulated driving, participants were asked to respond to tactile stimuli using the tactile detection response task (TDRT), a validated method of testing cognitive load during simulated driving. The concussion group reported significantly higher symptoms on the SCAT-5 than the comparison group. Performance on crystallized neurocognitive skills was similar between groups. Performance on fluid neurocognitive skills was significantly lower in the concussion than comparison group, although scores were in the normal range for both groups. Simulated driving was similar between groups, although there was a small but significant difference in variation in speed as well as TDRT miss rate, with worse performance by the concussion group. Symptom report on the SCAT-5 was significantly associated with TDRT miss rate. In addition, neurocognitive test scores significantly predicted TDRT reaction time and miss count with medium to large effect sizes. Results suggest that neurocognitive screening may be a useful tool for predicting capacity to return to drive. However, further research is needed to determine guidelines for how neuropsychological tests can be used to make return to driving recommendations and to evaluate effects of concussion on real world driving.

Variability in opioid pain medication prescribing for adolescent trauma patients in a sample of US pediatric trauma centers.

Objectives: The primary objective of this study was to examine opioid prescription frequency and identify differences across a national cohort of pediatric trauma centers in rates of prescribing opioids to injured adolescents at discharge. Methods: This was a retrospective observational study using electronic health records of injured adolescents (12-17 years) admitted to one of 10 pediatric trauma centers. Results: Of the 1345 electronic health records abstracted, 720 (53.5%, 95% CI 50.8 to 56.2) patients received opioid prescriptions at discharge with variability across sites (28.6%-72%). There was no association between patient factors and frequency of prescribing opioids. Center's trauma volume was significantly positively correlated with a higher rate of opioid prescribing at discharge (r=0.92, p=0.001). There was no significant difference between the frequency of opioid prescriptions at discharge among alcohol and other drugs (AOD)-positive patients (53.8%) compared with AOD-negative patients (53.5%). Conclusions: Across a sample of 10 pediatric trauma centers, just over half of adolescent trauma patients received an opioid prescription at discharge. Prescribing rates were similar for adolescent patients screening positive for AOD use and those screening negative. The only factor associated with a higher frequency of prescribing was trauma center volume. Consensus and dissemination of outpatient pain management best practices for adolescent trauma patients is warranted. Level of evidence: III-prognostic. Trial registration number: NCT03297060.

Patterns and Predictors of Professional Interpreter Use in the Pediatric Emergency Department.

BACKGROUND AND OBJECTIVES: Professional interpretation for patients with limited English proficiency remains underused. Understanding predictors of use is crucial for intervention. We sought to identify factors associated with professional interpreter use during pediatric emergency department (ED) visits. METHODS: We video recorded ED visits for a subset of participants (n = 50; 20% of the total sample) in a randomized trial of telephone versus video interpretation for Spanish-speaking limited English proficiency families. Medical communication events were coded for duration, health professional type, interpreter (none, ad hoc, or professional), and content. With communication event as the unit of analysis, associations between professional interpreter use and assigned interpreter modality, health professional type, and communication content were assessed with multivariate random-effects logistic regression, clustered on the patient. RESULTS: We analyzed 312 communication events from 50 ED visits (28 telephone arm, 22 video arm). Professional interpretation was used for 36% of communications overall, most often for detailed histories (89%) and least often for procedures (11%) and medication administrations (8%). Speaker type, communication content, and duration were all significantly associated with professional interpreter use. Assignment to video interpretation was associated with significantly increased use of professional interpretation for communication with providers (adjusted odds ratio 2.7; 95% confidence interval: 1.1-7.0). CONCLUSIONS: Professional interpreter use was inconsistent over the course of an ED visit, even for patients enrolled in an interpretation study. Assignment to video rather than telephone interpretation led to greater use of professional interpretation among physicians and nurse practitioners but not nurses and other staff.

Screening Adolescent Trauma Patients for Substance Use at 10 Pediatric Trauma Centers.

BACKGROUND: The American College of Surgeons Committee on Trauma recommends universal alcohol screening be part of the evaluation of admitted trauma patients. Yet, suboptimal screening rates have been reported for admitted adult and adolescent trauma patients. This lack of screening, in turn, has limited the ability of trauma services to provide patients with brief interventions during their hospital admission and subsequent referrals to treatment after discharge. The primary aim of this study was to examine current rates of alcohol and other drug screening with admitted injured adolescents across a national cohort of 10 pediatric trauma centers. METHODS: This retrospective observational study was nested within a larger adolescent screening, brief intervention, and referral to treatment implementation study (Clinicaltrials.gov NCT03297060). Ten pediatric trauma centers participated in a retrospective chart review of a random sample of adolescent trauma patients presenting for care between March 1, 2018, and November 30, 2018. RESULTS: Three hundred charts were abstracted across the 10 participating trauma centers (n = 30 per site). Screening rates varied substantially across centers from five (16.7%) to 28 (93.3%) of the 30 extracted charts. The most frequent screening type documented was blood alcohol concentration (BAC) (N = 80, 35.2% of all screens), followed by the CRAFFT (N = 79, 26.3%), and then the urine drug screen (UDS) (N = 77, 25.6%). The BAC test identified 11 patients as positive for recent alcohol use. The CRAFFT identified 11 positive patients. CONCLUSIONS: Alcohol and drug screening is underutilized for adolescents admitted to pediatric trauma centers. More research is warranted on how best to utilize the teachable moment of the pediatric trauma visit to ensure comprehensive screening of adolescent alcohol or other drug (AOD) use.

Deficiencies in Provider-Reported Interpreter Use in a Clinical Trial Comparing Telephonic and Video Interpretation in a Pediatric Emergency Department.

BACKGROUND: Professional interpretation improves health care quality and outcomes for limited English proficient (LEP) patients, yet interpreter use remains low even when interpretation is available remotely. The researchers analyzed the effect of remote interpretation (telephone or video) on pediatric emergency provider attitudes and behaviors around professional interpretation. METHODS: A cross-sectional questionnaire of pediatric emergency providers was conducted as part of a randomized trial of telephone vs. video interpretation with Spanish speaking LEP families. Providers recalled lapses of professional interpretation for medical communication (use of an ad hoc or no interpreter), if they had delayed or deferred communication due to the need for professional interpretation, and were asked about their satisfaction with the interpretation modality. Bivariate and multivariate analysis of professional interpreter use and communication behaviors were analyzed by self-report of study group assignment. RESULTS: One third of providers reported lapses of professional interpretation and many reported less frequent (45.6%) and deferred (34.6%) communication due to the need for interpretation. There was no significant difference in these outcomes between telephone and video assignment. Interpreter skill and technical difficulties were similar between groups. Providers assigned to telephone, compared to video, were more likely to be dissatisfied (p < 0.001) and to report that interpretation was ineffective (p = 0.002). CONCLUSION: Despite access to interpretation, providers caring for patients enrolled in a study of professional interpreter modalities reported frequent lapses in professional interpretation and deferring or delaying communication because an interpreter was needed. Addressing barriers to remote interpreter use will improve quality of care and health equity for LEP patients.

Identifying Modifiable Health Care Barriers to Improve Health Equity for Hospitalized Children.

BACKGROUND: Children from socially disadvantaged families experience worse hospital outcomes compared with other children. We sought to identify modifiable barriers to care to target for intervention. METHODS: We conducted a prospective cohort study of hospitalized children over 15 months. Caregivers completed a survey within 3 days of admission and 2 to 8 weeks after discharge to assess 10 reported barriers to care related to their interactions within the health care system (eg, not feeling like they have sufficient skills to navigate the system and experiencing marginalization). Associations between barriers and outcomes (30-day readmissions and length of stay) were assessed by using multivariable regression. Barriers associated with worse outcomes were then tested for associations with a cumulative social disadvantage score based on 5 family sociodemographic characteristics (eg, low income). RESULTS: Of eligible families, 61% (n = 3651) completed the admission survey; of those, 48% (n = 1734) completed follow-up. Nine of 10 barriers were associated with at least 1 worse hospital outcome. Of those, 4 were also positively associated with cumulative social disadvantage: perceiving the system as a barrier (adjusted ß = 1.66; 95% confidence interval [CI] 1.02 to 2.30), skill barriers (ß = 3.82; 95% CI 3.22 to 4.43), cultural distance (ß = 1.75; 95% CI 1.36 to 2.15), and marginalization (ß = .71; 95% CI 0.30 to 1.11). Low income had the most consistently strong association with reported barriers. CONCLUSIONS: System barriers, skill barriers, cultural distance, and marginalization were significantly associated with both worse hospital outcomes and social disadvantage, suggesting these are promising targets for intervention to decrease disparities for hospitalized children.

Evaluation of the effectiveness of traffic calming measures on vehicle speeds and pedestrian injury severity in Ghana.

Objectives: Each year, pedestrian injuries constitute over 40% of all road casualty deaths and up to 60% of all urban road casualty deaths in Ghana. This is as a result of the overwhelming dependence on walking as a mode of transport in an environment where there are high vehicular speeds and inadequate pedestrian facilities. The objectives of this research were to establish the (1) impact of traffic calming measures on vehicle speeds and (2) association between traffic calming measures and pedestrian injury severity in built-up areas in Ghana. Method: Vehicle speeds were unobtrusively measured in 38 selected settlements, including 19 with traffic calming schemes and 19 without. The study design used in this research was a matched case-control. A regression analysis compared case and control casualties using a conditional logistic regression. Results: Generally, the mean vehicle speeds and the proportion of vehicles exceeding the 50 km/h speed limit were significantly lower in settlements that have traffic calming measures compared to towns without any traffic calming measures. Additionally, the proportion of motorists who exceeded the speed limit was 30% or less in settlements that have traffic calming devices and the proportion who exceeded the speed limit was 60% or more in towns without any traffic calming measures. The odds of pedestrian fatality was significantly higher in settlements that have no traffic calming devices compared to those that have (odds ratio [OR] = 1.98; 95% confidence interval, 1.09-4.43). The protective effects of a traffic calming scheme that has a speed table was notably higher than those where there were no speed tables. Conclusion: It was clearly evident that traffic calming devices reduce vehicular speeds and, thus, the incidence and severity of pedestrian injuries in built-up areas in Ghana. However, the fact that they are deployed on arterial roads is increasingly becoming a road safety concern. Given the emerging safety challenges associated with speed calming measures, we recommend that their use be restricted to residential streets but not on arterial roads. Long-term solutions for improving pedestrian safety proposed herein include bypassing settlements along the highways to reduce pedestrians' exposure to traffic collisions and adopting a modern way of enforcement such as evidence-based laser monitoring in conjunction with a punishment regime that utilizes the demerit points system.

Head Impact Exposure in Youth Soccer and Variation by Age and Sex.

OBJECTIVE: To examine variation in head impact exposure (HIE) by age and sex in youth soccer. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: Youth soccer athletes (11-14 years old) in local clubs. EXPOSURES: Age and sex. OUTCOME MEASURES: Head impact exposure measured using adhesive-mounted accelerometers during 1 month of soccer. RESULTS: Forty-six youth athletes (54% female) participated. No athlete reported a concussion during the study. More males than females had at least 1 head impact ≥15 g (P = 0.02). Of those who sustained a head impact above the 15-g threshold (57%), females sustained HIE of greater magnitude than males (median 47.4 g vs 33.3 g, P = 0.04). Eighty-five percent of athletes on U14 teams had at least 1 head impact ≥15 g compared with 15% of athletes on U12 teams (P < 0.001). Poisson regression stratified by sex and controlling for team-suggested age effects were significant only for females (P = 0.02). There was significant variation in HIE by team. There were no decrements in concussion symptoms, health-related quality of life, or neuropsychological testing after 1 month of soccer play. CONCLUSIONS: There is significant variation in HIE in youth soccer, which seems to be influenced by age and sex. Further studies are needed to better understand potential significance for injury prevention.

Medical Home-Head Start Partnership to Promote Early Learning for Low-Income Children.

OBJECTIVE: To improve Early Head Start/Head Start (EHS/HS) screening, referral, and enrollment for children from diverse, low-income communities. METHOD: Using existing resources, we built a pediatric clinic-Head Start partnership. Key steps included (1) screening protocol and tracking system, (2) a community partner as a single point of referral contact, (3) provider education, and (4) monthly outcome reporting. A pre- and post-cross-sectional study design was used to evaluate outcomes, with medical chart review conducted for all wellness visits among children aged 0 to 4 years pre- and postintervention. RESULTS: The preintervention group included 223 patients. The postintervention group included 235 patients. EHS/HS screening improved significantly after the intervention, rising from 8% in the preintervention period to 46% in the postintervention period (odds ratio [OR] 10.5, 95% confidence interval [CI] [5.9, 19.4]). EHS/HS documented referral rates increased from 1% in the preintervention period to 20% in the postintervention period (OR 18.3, 95% CI [5.7, 93.6]). Thirty-two of the 42 patients in the postintervention group referred to EHS/HS were reached to determine enrollment status. Six children (14%) had enrolled in EHS/HS. CONCLUSION: With use of existing resources, a medical home-Head Start partnership can build an integrated system that significantly improves screening and referral rates to early learning programs.

Impact of automated photo enforcement of vehicle speed in school zones: interrupted time series analysis.

OBJECTIVE: Measure the impact of automated photo speed enforcement in school zones on motorist speed and speeding violation rates during school travel. METHODS: Automated enforcement cameras, active during school commuting hours, were installed around four elementary schools in Seattle, Washington, USA in 2012. We examined the effect of automated enforcement on motorist speeds and speed violation rates during the citation period (10 December 2012 to 15 January 2015) compared with the 'warning' period (1 November to 9 December 2012). We evaluated outcomes with an interrupted time series approach using multilevel mixed linear regression. RESULTS: Motorist speed violation rates decreased by nearly half in the citation period compared with the warning period (standardised incident rate ratio 0.53, 95% CI 0.42 to 0.66). The hourly maximum violation speed and mean hourly speeds decreased 2.1 MPH (95% CI -2.88 to -1.39) and 1.1 MPH (95% CI -1.64 to - 0.60), respectively. The impact of automated enforcement was sustained during the second year of implementation. CONCLUSION: Automated photo enforcement of speed limit in school zones was effective at reducing motorist speed violations and also achieved a significant reduction in mean motorist speed.

Audio-Recorded Discharge Instructions for Limited English Proficient Parents: A Pilot Study.

BACKGROUND: Parents with limited English proficiency (LEP) demonstrate lower comprehension of discharge instructions. A study was conducted to (1) determine the feasibility of providing a greeting card with language-specific, audio-recorded discharge instructions to LEP parents; (2) describe use of and satisfaction with the cards; and (3) evaluate card effect on instruction comfort with home care and comprehension. METHODS: LEP parents of children undergoing day surgery from April to September 2016 were eligible. Participants were randomized to usual discharge instructions, or usual instructions plus a three-minute card with language-specific audio instructions that could be replayed repeatedly. Parents were surveyed by telephone two to seven days postdischarge to assess card use and satisfaction, comfort with home care, and discharge instruction recall (medications, home care, follow-up, and return precautions). Parent-reported instructions were compared to instructions in the medical record; concordance was determined by two blinded reviewers. Due to difficulty achieving recruitment goals, analysis focused on feasibility and acceptability. RESULTS: Of 83 parents enrolled, 66 (79.5%) completed the follow-up survey. Most had not completed high school (61.0%) and spoke Spanish (89.2%). Parents reported high satisfaction with the card (4.5/5 for ease of use, helpfulness, and understandability). Ninety-four percent shared the card with others, and 45.2% reported listening > 5 times. Besides reviewing the care instructions generally, parents reported using the card to review medications and engage others in the child's care. CONCLUSION: Providing language-concordant, audio-recorded discharge instructions was feasible, and parents reported high satisfaction with and frequent use of the cards with multiple caregivers.

"Complete Streets" and Adult Bicyclist Fatalities: Applying G-Computation to Evaluate an Intervention That Affects the Size of a Population at Risk.

"Complete streets" policies require transportation engineers to make provisions for pedestrians, bicyclists, and mass transit users. These policies may make bicycling safer for individual cyclists while increasing the overall number of bicycle fatalities if more people cycle due to improved infrastructure. We merged county-level records of complete streets policies with Fatality Analysis Reporting System counts of cyclist fatalities occurring between January 2000 and December 2015. Because comprehensive county-level estimates of numbers of cyclists were not available, we used bicycle commuter estimates from the American Community Survey and the US Census as a proxy for the cycling population and limited analysis to 183 counties (accounting for over half of the US population) for which cycle commuting estimates were consistently nonzero. We used G-computation to estimate the effect of complete streets policies on overall numbers of cyclist fatalities while also accounting for potential policy effects on the size of the cycling population. Over a period of 16 years, 5,254 cyclists died in these counties, representing 34 fatalities per 100,000 cyclist-years. We estimated that complete streets policies made cycling safer, averting 0.6 fatalities per 100,000 cyclist-years (95% confidence interval: -1.0, -0.3) by encouraging a 2.4% increase in cycling but producing only a 0.7% increase in cyclist fatalities. G-computation is a useful tool for understanding the impact of policy on risk and exposure.

Provider Language Proficiency and Decision-Making When Caring for Limited English Proficiency Children and Families.

OBJECTIVE: To examine associations between self-assessed language ability and provision of clinical care without professional interpretation. METHODS: We conducted an anonymous web-based survey of pediatric residents at a large pediatric training program. Respondents self-rated their language ability, and then reported on their willingness to deliver clinical care without professional interpretation in standardized clinical scenarios. RESULTS: All pediatric residents completed the survey (n=81; 100%). Many residents (58 of the total sample) indicated at least rudimentary skills in a second language, and seven (9%) indicated they were proficient in Spanish. Eight-five percent had sometimes relied upon friends or family to communicate with parents. Most (69%) reported occasional use of Spanish-language skills to take a history or provide medical advice without the use of a professional interpreter. In contrast, in clinical scenarios where a child was believed to have a complex medical history, few residents (2.5%) felt comfortable using their language skills in the clinical encounter. Residents were willing to have their language ability assessed. CONCLUSIONS: Residents still face circumstances in which care proceeds without an interpreter. Discomfort with providing care in a second language grows with the perceived complexity of care, and yet a complex condition may not be apparent when communication barriers exist. Overcoming barriers to the use of professional interpretation may improve care for LEP children.

Cognitive Decline and Older Driver Crash Risk.

OBJECTIVES: To examine automobile crash risk associated with cognition in older drivers without dementia. DESIGN: Retrospective secondary analysis of longitudinal cohort study. SETTING: Our study used data from the Adult Changes in Thought (ACT) Study merged with Washington State crash reports and licensure records. Data were available from 2002 to 2015. PARTICIPANTS: Group Health enrollees from Washington State aged 65 and older with active driver's licenses (N=2,615). MEASUREMENTS: Cognitive function was assessed using the Cognitive Abilities Screening Instrument scored using item response theory (CASI-IRT). The study outcome was police-reported motor vehicle crash. We used a negative binomial mixed-effects model with robust standard errors clustered on the individual and considered associations between crash risk, level of cognition, and amount of decline since the previous study visit. Covariates included age, sex, education, alcohol, depression, medical comorbidities, eyesight, hearing, and physical function. Individuals were censored at dementia diagnosis, death, or failure to renew their license. RESULTS: Over an average of 7 years of follow-up, 350 (13%) people had at least one crash. A 1-unit lower CASI-IRT score was associated with a higher adjusted incidence rate ratio of crash of 1.26 (95% confidence interval=1.08-1.51). Beyond level of cognition, amount of cognitive decline between study visits was not associated with crash risk. CONCLUSION: This study suggests that, in older drivers, poorer performance on the CASI-IRT may be a risk factor for motor vehicle crashes, even in individuals without diagnosed dementia. Further research is needed to understand driving behavior and inform driving decisions for older adults with poor cognitive function.

Diagnosed dementia and the risk of motor vehicle crash among older drivers.

Older adults are an active and growing segment of drivers in the United States. We compared the risk of motor vehicle crash among older licensed drivers diagnosed with dementia to crash risk among older licensed drivers without diagnosis of dementia. This retrospective cohort study used data from Group Health (GH), a Washington State health maintenance organization. Research participants were members of GH, aged 65-79 during the study who lived in Washington State from 1999-2009. Participant health records were linked with police-reported crash and licensure records. We estimated the risk of crash for older drivers diagnosed with dementia compared to older drivers without diagnosis of dementia using a Cox proportional hazards model with robust standard errors, accounting for recurrent events (crashes). Multivariable models were adjusted for age, sex, history of alcohol abuse or depression, comorbidities, and medications. There were 29,730 eligible individuals with an active driving license. Approximately 6% were diagnosed with dementia before or during the study. The police-reported crash rate was 14.7 per 1000 driver-years. The adjusted hazard ratio of crash among older drivers with diagnosed dementia was 0.56 (95% CI 0.33, 0.95) compared to those without diagnosed dementia. On-road and simulator-based research showed older adults with dementia demonstrated impaired driving skill and capabilities. The observed lower crash risk in our study may result from protective steps to limit driving among older adults diagnosed with dementia. Future research should examine driving risk reduction strategies at the time of dementia diagnosis and their impact on reducing crash risk.

Mobile phone use among commercial drivers in Ghana: An important threat to road safety.

BACKGROUND: Ghana passed a law in 2012 banning the use of mobile phones while driving. However, data on compliance to the law has been lacking. OBJECTIVE: To examine factors associated with mobile phone use while driving among Ghanaian commercial drivers. METHODS: A survey was conducted among 627 commercial drivers (98.0% response rate). Bivariate and multivariate logistic regressions were performed to determine how a priori covariates influenced commercial drivers' use of phones while driving. The covariates included driver age, education, driving route distance, driving under the influence (DUI), and knowledge that phone use during driving causes distraction. RESULTS: Respondents were aware of the law (94.7%) but compliance was low (38%). Drivers who did not believe that cell phone use contributed to crash risk were more likely to report distracted driving (AOR 2.02,95%CI 1.05-3.9). Drivers who had completed primary (AOR 4.49,95%CI 1.14-17.78) or at least senior high school (AOR 6.89,95%CI 1.5-31.59) had increased odds of using the phone while driving, compared to those having no formal education. Drivers with 6-10 years (AOR 2.00,95%CI 1.00-3.98) or >10 years driving experience (AOR 2.87,95%CI 1.24-6.62) were more likely to report distracted driving compared to those with ≤5 years' experience. Drivers who travelled longer distances were more likely to report distracted driving (AOR 2.41,95%CI 1.23-4.71). Those who had never engaged in DUI were less likely to use the phone while driving (AOR 0.06,95%CI 0.01-0.43). CONCLUSION: Future prevention efforts for distracted driving in Ghana will require targeted distracted driving enforcement and education for commercial drivers and their passengers.

The Relationship Between Objectively Measured Walking and Risk of Pedestrian-Motor Vehicle Collision.

Safe urban walking environments may improve health by encouraging physical activity, but the relationship between an individual's location and walking pattern and the risk of pedestrian-motor vehicle collision is unknown. We examined associations between individuals' walking bouts and walking risk, measured as mean exposure to the risk of pedestrian-vehicle collision. Walking bouts were ascertained through integrated accelerometry and global positioning system data and from individual travel-diary data obtained from adults in the Travel Assessment and Community Study (King County, Washington) in 2008-2009. Walking patterns were superimposed onto maps of the historical probabilities of pedestrian-vehicle collisions for intersections and midblock segments within Seattle, Washington. Mean risk of pedestrian-vehicle collision in specific walking locations was assessed according to walking exposure (duration, distance, and intensity) and participant demographic characteristics in linear mixed models. Participants typically walked in areas with low pedestrian collision risk when walking for recreation, walking at a faster pace, or taking longer-duration walks. Mean daily walking duration and distance were not associated with collision risk. Males walked in areas with higher collision risk compared with females, while vehicle owners, residents of single-family homes, and parents of young children walked in areas with lower collision risk. These findings may suggest that pedestrians moderate collision risk by using lower-risk routes.

Relating Older Workers' Injuries to the Mismatch Between Physical Ability and Job Demands.

OBJECTIVE: We examined the association between job demand and occupational injury among older workers. METHODS: Participants were workers aged 50+ enrolled in the Health and Retirement Study, 2010 to 2014. Participants reported physical ability within three domains: physical effort, stooping/kneeling/crouching, and lifting. To measure subjective job demand, participants rated their job's demands within domains. We generated objective job demand measures through the Occupational Information Network (ONET). Using Poisson regression, we modeled the association between physical ability, job demand, and self-reported occupational injury. A second model explored interaction between job demand and physical ability. RESULTS: The injury rate was 22/1000 worker-years. Higher job demand was associated with increased injury risk. Within high job demands, lower physical ability was associated with increased injury risk. CONCLUSIONS: Older workers whose physical abilities do not meet job demands face increased injury risk.
