We conducted a responsibility analysis to determine whether drivers injured in motor vehicle collisions who test positive for Δ-9-tetrahydrocannabinol (THC) or other drugs are more likely have contributed the crash than those negative.Prospective case-control study.Trauma centres British Columbia, Canada.Injured required blood tests clinical purposes following collision.Excess whole remaining after use was obtained and broad-spectrum toxicology testing performed. The quantified alcohol THC...
The effect of cannabis legalization in Canada (in October 2018) on the prevalence injured drivers testing positive for tetrahydrocannabinol (THC) is unclear.We studied treated after a motor vehicle collision four British Columbia trauma centers, with data from January 2013 through March 2020. We included moderately (those whose condition warranted blood tests as part clinical assessment) whom excess remained was complete. Blood analyzed at provincial toxicology center. primary outcomes were...
Background: Baseline health and driving data might allow clinicians to personalize medical restrictions after implantable cardioverter-defibrillator (ICD) implantation. Methods: Using 22 years of population-based administrative from British Columbia, Canada, we identified licensed drivers with a first ICD implantation between 1998 2018. After stratifying by indication (primary vs secondary prevention sudden cardiac death), applied regression techniques baseline estimate each driver's 1-year...
Limited empirical evidence informs fitness-to-drive recommendations after implantable cardioverter-defibrillator (ICD) implantation. Cohort designs can be deceptive because ICD recipients differ from control individuals and may temporarily cease driving This study sought to generate inform medical restrictions We used population-based data identify all drivers involved in a serious motor vehicle crash British Columbia, Canada, 1997 2019. Exposure was defined as implantation the 6 months...
We evaluated the public health benefits of traffic laws targeting speeding and drunk drivers (British Columbia, Canada, September 2010).We studied fatal crashes ambulance dispatches hospital admissions for road trauma, using interrupted time series with multiple nonequivalent comparison series. determined estimates effect linear regression models incorporating an autoregressive integrated moving average error term. used neighboring jurisdictions (Alberta, Saskatchewan, Washington State) as...
Many medications impair driving skills yet their influence on collision risk remains uncertain. We aimed to systematically investigate the of responsibility associated with common classes prescription medications.In this population-based case-control study we analysed linked and health records in British Columbia, Canada from Jan 1, 1997, Dec 31, 2016. The cohort included all drivers involved an incident (defined as first after 3 collision-free years) that resulted a police report. scored...

Medical driving restrictions are burdensome, yet syncope recurrence while can cause a motor vehicle crash (MVC). Few empirical data inform current after syncope.To examine MVC risk among patients visiting the emergency department (ED) first-episode syncope.A population-based, retrospective observational cohort study of was performed in British Columbia, Canada. Patients any 6 urban EDs for and collapse were age- sex-matched to 4 control same ED month condition other than syncope. Patients'...
Motor vehicle collisions (MVCs) remain a leading cause of death and serious injury in Canadian children. In July 2008, British Columbia introduced child safety seat legislation that aimed to reduce the number children killed or injured MVCs. This upgraded previous (introduced 1985) affected zero three those four eight years age. The objective present study was evaluate effectiveness this legislation.Deidentified police reports for all MVCs involving zero- 14-year-olds (2000 2012) were used...
Introduction When managing opioid overdose (OD) patients, the optimal naloxone regimen should rapidly reverse respiratory depression while avoiding withdrawal. Published administration guidelines have not been empirically validated and most were developed before fentanyl OD was common. In this study, rates of withdrawal symptoms (OW) reversal toxicity in patients treated with two dosing regimens evaluated.Methods retrospective matched cohort health records who experienced an urban emergency...
To examine the relationship between schizophrenia, antipsychotic medication adherence and driver responsibility for motor vehicle crash. Retrospective observational cohort study using 20 years of population-based administrative health driving data. British Columbia, Canada. Licensed drivers who were involved in a police-attended crash Columbia over 17-year interval (2000-16). Incident schizophrenia was identified hospitalisation physician services Antipsychotic estimated prescription fill...
Background British Columbia, Canada is a geographically large jurisdiction with varied environmental and socio-cultural contexts. This cross-sectional study examined variation in motor vehicle crash rates across 100 police patrols to investigate the association of crashes key explanatory factors. Methods Eleven outcomes (total crashes, injury fatal speed related total fatalities, single-vehicle night-time rear-end collisions, collisions involving heavy vehicles, pedestrians, cyclists, or...
Climate change has been deemed the biggest global health threat of 21st century. One consequence climate is increasing frequency and severity forest fires. Smoke from wildfires ability to negatively impact air quality over large distances. The aim this study was examine association that had on emergency department visits for cardiac, respiratory psychiatric/behavioral chief complaints during fire season in Vancouver, British Columbia. period January 1, 2009 – December 31, 2019. Forest...
Background Physicians are often asked to counsel patients about driving safety after syncope, yet little empirical data guides such advice. Methods We identified a population-based retrospective cohort of 9,507 individuals with driver license who were discharged from any six urban emergency departments (EDs) diagnosis ’syncope and collapse’. examined all police-reported crashes that involved member as occurred between 1 January 2010 31 December 2016. categorized crash-involved drivers...
Background: Evidence on the impact of pediatric palliative care programs (PPCP) resource utilization is scarce and requires broader measures to include beyond hospital setting. Objective: This research aims provide a Canadian comparative analysis between children in PPCP with those under usual care, including hospice use inpatient measurement. Methods: We conducted retrospective matched-pairs (disease age at death) cohort comparison who died versus (never enrolled PPCP), from 2008 2012....
Drug driving is an emerging global road safety problem. As the prevalence of alcohol-impaired decreases, and as more jurisdictions decriminalize or legalize cannabis, it increasingly important for policy makers to have accurate information on pattern drug driving. Unfortunately, this data not widely available World Health Organization identifies lack knowledge gap.In paper, we discuss limitations current methods monitoring use in drivers. We then present a novel methodology from multi-centre...
This was a prospective observational study.The characteristics of cannabis-involved motor vehicle collisions are poorly understood. study injured drivers identifies demographic and collision associated with high tetrahydrocannabinol (THC) concentrations.The conducted in 15 Canadian trauma centres between January 2018 December 2021.The cases (n = 6956) comprised who required blood testing as part routine care.We quantified whole THC alcohol concentration (BAC) recorded driver sex, age postal...
Control of vehicle speed is a central tenet the safe systems approach to road safety. Most research shows that raising limits results in more injuries. Advocates higher argue this conclusion based on older research, traffic fatalities are decreasing despite limits, and modern vehicles able safely travel at speeds. These arguments were used justify rural highways British Columbia, Canada (July 2014). We an interrupted time series evaluate impact these limit increases fatal crashes,...
