A systematic review of the risk of motor vehicle collision after stroke or transient ischemic attack

The development and validation of a Japanese hazard perception task

OBJECTIVES

This study aimed to validate the hazard perception task developed for Japanese drivers with brain damage.

METHODS

A total of 36 professional driving instructors, 67 older adult drivers, 39 young drivers, and 72 patients with brain damage participated in the study. A video-based hazard perception task measured the hazard perception skills of each group. Participants were instructed to touch the screen as soon as they identified a hazard. Outcome measures included the number of hazards identified and response latency. Comparisons were made between groups for each hazard type: environmental prediction hazard (EPH) and behavioral prediction hazard (BPH).

RESULTS

Patients with brain damage demonstrated fewer hazard detections and longer response latencies than driving instructors and older adult drivers, regardless of the hazard type. The hazard perception skills of patients with brain damage were comparable to those of young drivers across both hazard types. Driving instructors exhibited the highest number of hazard detections and the fastest response latencies among all groups, with differences being more pronounced for EPH than for BPH.

CONCLUSIONS

Thus, the validity of the hazard perception task developed for Japanese drivers with brain damage was confirmed. Future research should examine the predictive validity of the developed task, particularly its relationship with crash rates in individuals with brain damage.

Ascertainment and description of pedestrian and bicycling injuries and fatalities in Ontario from administrative health records 2003-2017: contributions of non-collision falls and crashes

INTRODUCTION

Pedestrian and bicycling injuries may be less likely to be captured by traffic injury surveillance relying on police reports. Non-collision injuries, including pedestrian falls and single bicycle crashes, may be more likely than motor vehicle collisions to be missed. This study uses healthcare records to expand the ascertainment of active transportation injuries and evaluate their demographic and clinical features.

METHODS

We identified pedestrian and bicyclist injuries in records of deaths, hospitalisations and emergency department visits in Ontario, Canada, between 2002 and 2017. We described the most common types of clinical injury codes among these records and assessed overall counts and proportions of injury types captured by each ascertainment definition. We also ascertained relevant fall injuries where the location was indicated as 'street or highway'.

RESULTS

Pedestrian falls represented over 50% of all pedestrian injuries and affected all age groups, particularly non-fatal falls. Emergency department records indicating in-traffic bicycle injuries not involving a collision with motor vehicles increased from 14% of all bicycling injury records in 2003 to 34% in 2017. The overall number of injuries indicated by these ascertainment methods was substantially higher than official counts derived from police reports.

CONCLUSION

The use of healthcare system records to ascertain bicyclist and pedestrian injuries, particularly to include non-collision falls, can more fully capture the burden of injury associated with these transportation modes.

Stroke Recurrence among Stroke Patients Referred for Driving Assessment and Rehabilitation: A Cohort Study

Returning to driving is one of the priorities for stroke survivors. However, the fear of the risk of recurrent stroke has led to concern about allowing driving post-stroke. This study was performed to study the impact of various vascular risk factors on stroke recurrence among drivers referred to our national referral center for Driving Assessment and Rehabilitation Program (DARP). Medical records of subjects who were diagnosed to have a stroke and were referred to DARP were retrospectively reviewed. Data on demographics (age and gender) and vascular risk factors (hypertension-HT, diabetes mellitus-DM, hyperlipidemia-HL, cigarette smoking-SM, previous stroke-PS, and heart disease-HD) were collected. Subjects were contacted and records scrutinized for a report of recurrent stroke. A total of 133 subjects were recruited, median 54 years (range 20-77 years), 95.5% male, 59.4% had HT, 32.3% DM, 65.4% HL, 43.6% SM, 3.8% PS, and 8.3% HD. Over a median follow-up of 30 months (range 1-78 months), the recurrence rate of stroke was 11.3%, 3.69/100 patient-years. On uni-variable analysis, the risk of stroke recurrence rose with age (HR 1.08, 95%CI 1.02-1.15, p = 0.01) and heart disease (HR 5.77, 95%CI 1.46-22.83, p = 0.01). On multivariable analysis, only age remained significant (HR 1.07, 95%CI 1.00-1.13, p = 0.045). Among those aged > 60 years, the HR was 3.88 (95%CI 1.35-11.20, p = 0.012). The risk of stroke recurrence is higher among older drivers and is not influenced by other vascular factors.

Rethinking Driving Against Medical Advice: The Situated Nature of Driving After Stroke

Background: As stroke can result in functional impairments that impact driving ability, many jurisdictions mandate a 30-day period of driving restriction post-stroke. However, between 26% and 38% of clients drive against medical advice during this period. Purpose: Informed by critical reflexivity of the literature and the first author's practice, this critical analysis paper (1) explicates and critiques how adherence to guidelines regarding driving after stroke in the first 30 days is conceptualized in individualistic, biomedically centred research and (2) argues for expanded understandings of driving based on a transactional occupational perspective. Key Issues: Individualistic, biomedical perspectives view driving against medical advice as an individually located phenomenon, generating partial understandings and individually focused solutions. Re-conceptualizing driving after stroke as a transactional occupational choice provides a productive basis for understanding and addressing driving within practice and research. Implications: Concepts from occupational science can generate new insights for research and client-centred practice regarding driving following stroke.

Association Between Young-Onset Dementia and Risk of Hospitalization for Motor Vehicle Crash Injury in Taiwan

IMPORTANCE

Several studies have suggested that older-onset dementia is associated with an increased risk of motor vehicle crash injury (MVCI). However, evidence of an association between young-onset dementia and the risk of MVCI is insufficient, particularly in Asia.

OBJECTIVE

To investigate the association between young-onset dementia and MVCI-related hospitalization in Taiwan.

DESIGN, SETTING, AND PARTICIPANTS

In this nationwide, population-based cohort study in Taiwan, a cohort of 39 344 patients aged 40 to 64 years with incident dementia diagnosed between 2006 and 2012 was matched 1:1 with a cohort of participants without dementia by age, sex, and index year (initial diagnosis of dementia). Participants were identified from Taiwan's National Health Insurance Research Database (NHIRD). Data were analyzed between March 25 and October 22, 2021.

EXPOSURES

Dementia, defined by International Classification of Diseases, Ninth Revision, Clinical Modification codes.

MAIN OUTCOMES AND MEASURES

Hospitalization for MVCI, determined using linked data from Taiwan's Police-Reported Traffic Accident Registry and the NHIRD from January 1, 2003, to December 31, 2015. Hazard ratios (HRs) for MVCI-related hospitalization were estimated using Cox proportional hazards regression models adjusted for sex, age, salary-based insurance premium, urbanization level, and comorbidities.

RESULTS

Of the 78 688 participants, 47 034 (59.8%) were male; the mean (SD) age was 54.5 (7.4) years. During the 10-year follow-up period, the incidence density of MVCI-related hospitalization was 45.58 per 10 000 person-years (95% CI, 42.77-48.39 per 10 000 person-years) among participants with dementia and 24.10 per 10 000 person-years (95% CI, 22.22-25.99 per 10 000 person-years) among participants without dementia. Compared with participants without dementia, patients with young-onset dementia were at higher risk of MVCI-related hospitalization (adjusted HR [aHR], 1.83; 95% CI, 1.63-2.06), especially those in younger age groups (aged 40-44 years: aHR, 3.54; 95% CI, 2.48-5.07) and within a shorter period (within 1 year of follow-up: aHR, 3.53; 95% CI, 2.50-4.98) after dementia was diagnosed. Patients with young-onset dementia also had a higher risk of being a pedestrian when the crash occurred (aHR, 2.89; 95% CI, 2.04-4.11), having an intracranial or internal injury (aHR, 2.44; 95% CI, 2.02-2.94), and having a severe injury (aHR, 2.90; 95% CI, 2.16-3.89).

CONCLUSIONS AND RELEVANCE

In this retrospective cohort study, patients in Taiwan with a diagnosis of young-onset dementia had a higher risk of MVCI-related hospitalization than did individuals without dementia and the risk varied by age, disease duration, transport mode, injury type, and injury severity. These findings suggest a need for the planning of strategies to prevent transportation crashes among patients with young-onset dementia.

Age-Related Diseases and Driving Safety

Due to demographic changes, the number of older drivers is steadily increasing. Mobility is highly relevant for leading an independent life in the elderly. It largely depends on car driving, which is a complex task requiring a multitude of cognitive and motor skills vulnerable to age- related functional deterioration. The almost inevitable effects of senescence may be potentiated by age-related diseases, such as stroke or diabetes mellitus. Respective pharmacological treatment may cause side effects, additionally affecting driving safety. The present article reviews the impact of age-related diseases and drug treatment of these conditions on driving fitness in elderly drivers. In essence, we focus on diseases of the visual and auditory systems, diseases of the central nervous system (i.e., stroke, depression, dementia and mild cognitive disorder, and Parkinson's disease), sleep disorders, as well as cardiovascular diseases, diabetes mellitus, musculoskeletal disorders, and frailty. We will outline the role of functional tests and the assessment of driving behavior (by a driving simulator or in real traffic), as well as the clinical interview including questions about frequency of (near) accidents, etc. in the evaluation of driving fitness of the elderly. We also address the impact of polypharmacy on driving fitness and end up with recommendations for physicians caring for older patients.

"Chance Takers Are Accident Makers": Are Patients With Epilepsy Really Taking a Chance When They Drive?

This review compiles scientific data about the real dangers faced by people with epilepsy (PWE) who drive. Those include risks of motor vehicle accidents (MVA) in PWE as compared with controls (individuals without epilepsy) and as compared with persons with other medical conditions that impact fitness to drive. Data regarding Accident rates as related to seizure free intervals (SFI), single vs. multiple seizure events, and/or antiseizure drug (ASD) taper and reintroduction are discussed. Variation in state, national, and international laws and guidance for non-commercial and commercial drivers is highlighted, along with some related reasons for driving restrictions. The review concludes by emphasizing the importance of physicians educating patients about local driving laws and about risks of ASD non-adherence. The need for a broader, multi-stakeholder re-examination of driving regulations for PWE is noted.
