Abstract
INTRODUCTION Pedestrian and cyclist injuries represent a preventable burden to Canadians. Police-reported collision data include information on where such collisions occur but under-report the number of collisions. The primary objective of this study was to compare the number of police-reported collisions with emergency department (ED) visits and hospitalisations in Toronto, Canada. METHODS Police-reported collisions were provided by Toronto Police Services (TPS). Data included the location of the collision, approximate victim age and whether the pedestrian or cyclist was killed or seriously injured. Health services data included ED visits in the National Ambulatory Care Reporting System and hospitalisations from the Discharge Abstract Database using ICD-10 codes for pedestrian and cycling injuries. Data were compared from 2016 to 2021. RESULTS Injuries reported in the health service data were higher than those reported in the TPS for cyclists and pedestrians. The discrepancy was the largest for cyclists treated in the ED, with TPS capturing 7.9% of all cycling injuries. Cyclist injuries not involving a motor vehicle have increased since the start of the pandemic (from 3629 in 2019 to 5459 in 2020 for ED visits and from 251 in 2019 to 430 for hospital admissions). IMPLICATIONS While police-reported data are important, it under-reports the burden. There have been increases in cyclist collisions not involving motor vehicles and decreases in pedestrian injuries since the start of the pandemic. The results suggest that using police data alone when planning for road safety is inadequate, and that linkage with other health service data is essential.

Abstract
This systematic review examines studies of traffic injury that involved linkage of police crash data and hospital data and were published from 1994 to 2023 worldwide in English. Inclusion and exclusion criteria were the basis for selecting papers from PubMed, Web of Science, and Scopus, and for identifying additional relevant papers using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and supplementary snowballing (n = 60). The selected papers were reviewed in terms of research objectives, data items and sample size included, temporal and spatial coverage, linkage methods and software tools, as well as linkage rates and most significant findings. Many studies found that the number of clinically significant road injury cases was much higher according to hospital data than crash data. Under-estimation of cases in crash data differs by road user type, pedestrian cases commonly being highly under-counted. A limited number of the papers were from low- and middle-income countries. The papers reviewed lack consistency in what was reported and how, which limited comparability.

[PMID: 36399963 DOI: 10.1016/j.aap.2022.106895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 10/05/2022] [Accepted: 11/03/2022] [Indexed: 06/16/2023]
Abstract
Contraflow cycling on one-way streets is a low cost intervention that research shows can improve the cycling experience and increase participation. Evidence from several studies suggest that cyclists on contraflows have a lower crash risk. However, implementing contraflow cycling is often controversial, including in the United Kingdom (UK). In this paper we examine whether contraflow cycling on one-way streets alters crash or casualty rates for pedal cyclists. Focusing on inner London boroughs between 1998 and 2019, we identified 508 road segments where contraflow cycling was introduced on one-way streets. We identified road traffic crashes occurring within 10 m of these segments and labelled them as pre-contraflow, contraflow or contraflow removed crashes. We calculated rates using the number of crashes or casualties divided by the time exposed and generated 95 % confidence intervals using bootstrap resampling. We adjusted the rates for changes in cordon cycling volume and injury severity reporting. There were 1498 crashes involving pedal cyclists: 788 pre-contraflow, 703 contraflow and 7 following contraflow removal. There was no change in adjusted overall pedal cyclist crash or casualty rates when contraflow cycling was introduced. Proximity to a junction doubled the crash rate. The crash rate when pedal cyclists were travelling contraflow was the same as those travelling with flow. We have found no evidence that introducing contraflow cycling increases the crash or casualty rate for pedal cyclists. It is possible that such rates may indeed fall when contraflow cycling is introduced if more accurate spatio-temporal cycling volume data was available. We recommend all one-way streets are evaluated for contraflow cycling but encourage judicious junction design and recommend UK legislative change for mandatory-two-way cycling on one-way streets unless exceptional circumstances exist.

Abstract
Road traffic collisions are a major cause of traumatic brain injury. However, the
relationship between road traffic collision dynamics and traumatic brain injury
risk for different road users is unknown. We investigated 2065 collisions from
Great Britain’s Road Accident In-depth Studies collision database
involving 5374 subjects (2013–20). Five hundred and ninety-five subjects
sustained a traumatic brain injury (20.2% of 2940 casualties), including
315 moderate–severe and 133 mild–probable injuries. Key
pathologies included skull fracture (179, 31.9%), subarachnoid
haemorrhage (171, 30.5%), focal brain injury (168, 29.9%) and
subdural haematoma (96, 17.1%). These results were extended nationally
using >1 000 000 police-reported collision casualties.
Extrapolating from the in-depth data we estimate that there are
∼20 000 traumatic brain injury casualties (∼5000
moderate–severe) annually on Great Britain’s roads, accounting for
severity differences. Detailed collision investigation allows vehicle collision
dynamics to be understood and the change in velocity (known as
delta-V) to be estimated for a subset of in-depth collision
data. Higher delta-V increased the risk of
moderate–severe brain injury for all road users. The four key pathologies
were not observed below 8 km/h delta-V for
pedestrians/cyclists and 19 km/h delta-V for car
occupants (higher delta-V threshold for focal injury in both
groups). Traumatic brain injury risk depended on road user type,
delta-V and impact direction. Accounting for
delta-V, pedestrians/cyclists had a 6-times higher
likelihood of moderate–severe brain injury than car occupants. Wearing a
cycle helmet during a collision was protective against overall and
mild-to-moderate-to-severe brain injury, particularly skull fracture and
subdural haematoma. Cycle helmet protection was not due to travel or impact
speed differences between helmeted and non-helmeted cyclist groups. We
additionally examined the influence of the delta-V direction.
Car occupants exposed to a higher lateral delta-V component had
a greater prevalence of moderate–severe brain injury, particularly
subarachnoid haemorrhage. Multivariate logistic regression models created using
total delta-V value and whether lateral
delta-V was dominant had the best prediction capabilities
(area under the receiver operator curve as high as 0.95). Collision notification
systems are routinely fitted in new cars. These record delta-V
and automatically alert emergency services to a collision in real-time. These
risk relationships could, therefore, inform how routinely fitted automatic
collision notification systems alert the emergency services to collisions with a
high brain injury risk. Early notification of high-risk scenarios would enable
quicker activation of the highest level of emergency service response.
Identifying those that require neurosurgical care and ensuring they are
transported directly to a centre with neuro-specialist provisions could improve
patient outcomes.

Abstract
This paper examines infrastructural and route environment correlates of cycling injury risk in Britain. We used a case-crossover design, randomly selecting control sites from modelled cyclist routes, comparing these with sites where cyclists were injured. We then used conditional logistic regression for matched case-control groups modelling to compare characteristics of control and injury sites. Intersections were strongly associated with injury risk. High streets were associated with an elevated injury risk in final adjusted models, as was road type being primary, and a more downhill gradient. Lower speed limits and lower motor traffic connectivity were initially associated with lower injury risk, but these effects were no longer statistically significant in adjusted models. Increased road width was associated with increased injury risk in all models. Increased injury risk was associated in all models with presence of bus lane (somewhat mitigated at stops), guardrail, and fuel station or parking lot. Presence of parked cars in street view data raised injury risk in fully adjusted models, as did congestion (measured by low morning peak speeds), while higher volumes of people cycling along the street reduced it. In fully adjusted models, a statistically significant increase in risk was associated with presence of an on-road painted cycle lane. Most cycle lanes or tracks at control and injury sites were very poor, with narrow lanes, shared footways, and lack of protection at junctions. Given findings from other studies showing protective effects of cycle infrastructure, Britain must create higher quality cycle provision, avoiding narrow on-road painted lanes.

Abstract
Background & Objectives: The construction industry is a leading contributor to occupational injuries. First Information Reports (FIRs) of Indian Police are a potential data source for construction injuries. The aim of this study was to estimate the completeness of ascertainment of construction site injuries by FIRs. Methods: This was a two-sample capture-recapture study of construction site injuries sustained in the year 2017 in Delhi, India. The first capture sample was data extracted from FIRs. The second capture sample comprised data extracted from the Employee State Insurance Corporation (ESIC) and the Commissioners of Workmen Compensation. The Chapman estimator was used to estimate, with 95% confidence intervals, the total numbers of fatal and non-fatal injuries. Results: FIRs ascertained 374 injuries (110 fatal and 264 non-fatal) while the combined data of ESIC and workmen compensation claims ascertained 80 injuries (48 fatal and 32 non-fatal). The capture-recapture analysis estimated that 1,011 (95% CI: 873 to 1149) injuries: 258 (95% CI: 221 to 295) fatal injuries and 873 (95% CI: 765 to 1053) non-fatal injuries were sustained in Delhi in 2017. Interpretation & Conclusions: FIRs ascertain approximately one-third of all construction site injuries. In the absence of any other data source, FIRs may be used as the basis of a construction injury surveillance system, recognizing that any estimates made using these data must be adjusted to allow for the approximately two-thirds of injuries not reported to the police. Further research is needed to identify reasons for some injuries not being reported to the police, in order to help to develop a strategy to improve the completeness of ascertainment of construction site injuries for the future.

Lewsey J, Haghpanahan H, Mackay D, McIntosh E, Pell J, Jones A. Impact of legislation to reduce the drink-drive limit on road traffic accidents and alcohol consumption in Scotland: a natural experiment study. PUBLIC HEALTH RESEARCH 2019.

Abstract
Background
It is widely recognised that drink driving is a leading cause of road traffic accidents (RTAs). There is evidence that changing the drink-drive limit from a blood alcohol concentration of 0.08 to 0.05 g/dl is effective in reducing RTAs. Scotland changed the blood alcohol concentration limit to 0.05 g/dl on 5 December 2014.
Aims
To assess whether or not the numbers and rates of RTAs and per capita alcohol consumption in Scotland were reduced because of the 2014 drink-drive legislation. To assess whether or not the 2014 change in legislation provided good value for money.
Design
A natural experimental, quantitative study. The control group was England and Wales, that is, the other countries in Great Britain, where the drink-drive legislation remained unchanged.
Setting
Great Britain.
Participants
The entire population of Scotland, England and Wales for the period of January 2013–December 2016.
Intervention
The change to drink-drive legislation in Scotland.
Outcome measures
The counts and rates of RTAs; and per capita alcohol consumption.
Methods
For the numbers and rates of RTAs (both traffic flow and population denominators were used), and separately for the intervention and control trial groups, negative binomial regression models were fitted to panel data sets to test for a change in outcome level after the new 2014 legislation was in place. To obtain a ‘difference-in-differences’ (DiD)-type measure of effect, an interaction term between the intervention group indicator and the binary covariate for indicating pre and post change in legislation (‘pseudo’-change for the control group) was assessed. For off- and on-trade per capita alcohol sales, and separately for the intervention and control trial group, seasonal autoregressive integrated moving average error models were fitted to the relevant time series.
Results
The change to drink-drive legislation was associated with a 2% relative decrease in RTAs in Scotland [relative risk (RR) 0.98, 95% CI 0.91 to 1.04; p = 0.53]. However, the pseudo-change in legislation was associated with a 5% decrease in RTAs in England and Wales (RR 0.95, 95% CI 0.90 to 1.00; p = 0.05). For RTA rates, with traffic flow as the denominator, the DiD-type estimate indicated a 7% increase in rates for Scotland relative to England and Wales (unadjusted RR 1.07, 95% CI 0.98 to 1.17; p = 0.1). The change to drink-drive legislation was associated with a 0.3% relative decrease in per capita off-trade sales (–0.3%, 95% CI –1.7% to 1.1%; p = 0.71) and a 0.7% decrease in per capita on-trade sales (–0.7%, 95% CI –0.8% to –0.5%; p < 0.001).
Conclusion
The change to drink-drive legislation in Scotland in December 2014 did not have the expected effect of reducing RTAs in the country, and nor did it change alcohol drinking levels in Scotland. This main finding for RTAs was unexpected and the research has shown that a lack of enforcement is the most likely reason for legislation failure.
Future work
Investigations into how the public interpret and act on changes in drink-drive legislation would be welcome, as would research into whether or not previous change in drink-drive legislation effects on RTAs in other jurisdictions are associated with the level of enforcement that took place.

Abstract
OBJECTIVES Transport injuries (TI) are ranked as one of the leading causes of death, disability, and property loss worldwide. This paper provides an overview of the burden of TI in the Eastern Mediterranean Region (EMR) by age and sex from 1990 to 2015. METHODS Transport injuries mortality in the EMR was estimated using the Global Burden of Disease mortality database, with corrections for ill-defined causes of death, using the cause of death ensemble modeling tool. Morbidity estimation was based on inpatient and outpatient datasets, 26 cause-of-injury and 47 nature-of-injury categories. RESULTS In 2015, 152,855 (95% uncertainty interval: 137,900-168,100) people died from TI in the EMR countries. Between 1990 and 2015, the years of life lost (YLL) rate per 100,000 due to TI decreased by 15.5%, while the years lived with disability (YLD) rate decreased by 10%, and the age-standardized disability-adjusted life years (DALYs) rate decreased by 16%. CONCLUSIONS Although the burden of TI mortality and morbidity decreased over the last two decades, there is still a considerable burden that needs to be addressed by increasing awareness, enforcing laws, and improving road conditions.

Abstract
OBJECTIVE The impact of sociodemographic aspects and comorbidities on the inpatient hospital care costs of traffic victims are not clear. The main goal of this study is to provide insights into the sociodemographic characteristics and clinical conditions (including comorbidities) of the victims that result in higher hospital costs. PARTICIPANTS For the period 2009-2011, people admitted to a hospital as a result of a road traffic crash (N=64,304) were identified in the national Minimal Hospital Dataset, after which they were linked to their respective claims data from the sickness funds. METHODS A generalized linear model was used to analyse hospital costs controlling for roadway user categories, demographics (gender, age, individual socioeconomic status (SES)), and clinical factors (the nature, location, and severity of injury, and comorbidities). RESULTS The median hospital cost was € 2801 (IQR € 1510-€ 7175, 2015 Euros). There was no significant difference between gender. Low SES inpatients incurred 16% (95% CI: 14%-18%) higher hospital costs than inpatients of high SES. The presence of comorbidities was associated with an increased hospital cost, however with varying magnitude. For example traffic victims suffering from dementia incur significantly higher hospital costs than those who were not (49% higher, 95% CI: 44%-53%), whereas diabetes was associated with a smaller increase in costs compared to non-diabetics (13%, 95% CI: 10%-16%). CONCLUSION Comorbidities and low SES are associated with higher hospital costs for traffic victims, notwithstanding their age, and the nature and the severity of their injury. The broad variability of hospital costs among trauma inpatients should be accounted for when reconsidering financing models. Furthermore, the strong predictive value of some comorbidities and SES on hospital costs should be considered when projections of future health care utilisation in traffic safety scenarios are prepared.

[PMID: 27620929 DOI: 10.1016/j.jsr.2016.05.002] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/30/2015] [Revised: 04/20/2016] [Accepted: 05/17/2016] [Indexed: 06/06/2023]
Abstract
INTRODUCTION The study of non-fatal road traffic injuries is growing in importance. Since there are rarely comprehensive injury datasets, it is necessary to combine different sources to obtain better estimates on the extent and nature of the problem. Record linkage is one such technique. METHOD In this study, anonymized datasets from three separate sources of injury data in Ireland: hospitals, police, and injury claims are linked using probabilistic and deterministic linkage techniques. A method is proposed that creates a 'best' set of linked records for analysis, useful when clerical review of undecided cases is not feasible. RESULTS The linkage of police and hospital datasets shows results that are similar to those found in other countries, with significant police understatement especially of cyclist and motorcyclist injuries. The addition of the third dataset identifies a large number of additional injuries and demonstrates the error of using only the two main sources for injury data. PRACTICAL APPLICATION The study also underlines the risk in relying on the Lincoln-Petersen capture-recapture estimator to provide an estimate of the total population concerned. CONCLUSION The data show that road traffic injuries are significantly more numerous than either police or hospital sources indicate. It is also argued that no single measure can fully capture the range of impacts that a serious injury entails.

Xiong L, Zhu Y, Li L. Risk Factors for Motorcycle-related Severe Injuries in a Medium-sized City in China. AIMS Public Health 2016; 3:907-922. [PMID: 29546203 PMCID: PMC5690413 DOI: 10.3934/publichealth.2016.4.907] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2016] [Accepted: 11/04/2016] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Motorcycle vehicles are frequent in China, especially in the small and medium sized cities. Road traffic collisions involving motorcycles often result in severe injuries. We aimed to identify risk factors for severe injuries in inpatients sustaining motorcycle collisions. METHODS Patients with road traffic injuries involving motorcycles who presented to the neurosurgery and orthopedic departments of three major comprehensive hospitals in Shantou city were reviewed from October 2012 to June 2013. Data from 349 patients was investigated. Crash and injury characteristics were documented by interviewing patients, their family members, and their doctors. Binary logistic regression was used to determine risk factors for severe injuries. RESULTS There were 253 males (72.49%) and 96 females (27.51%), with a male to female ratio of 2.64:1. The mean age was 38.21±17.32 years. One-hundred and fifty patients were in the severe injury group with a mean injury severity score (ISS) of 15.34±9.13. The simple and multiple logistic model showed that males, lack of safeguards, morning and night hours, non-urban areas, collision of a motorcycle with a cycle, ambulance transportation to hospital, admission to a neurosurgery department, lack of traffic control, unobstructed traffic, and poor visibility were all the risk factors. CONCLUSIONS This research highlights some problems: less helmet wearing in motorcyclists and cyclists, rural injuries being more serious than urban ones, and head injuries being the main diagnosis in severe injuries. The result of this research is predictable. If the safety equipment is required to be used, such as helmets, and the traffic environment is improved, such as traffic flow, medical resources to injuries and deaths is seasonable, then traffic safety will be improved and accidents will be reduced.

Prevalence and factors associated with road traffic crash among taxi drivers in Mekelle town, northern Ethiopia, 2014: a cross sectional study. PLoS One 2015; 10:e0118675. [PMID: 25781940 PMCID: PMC4363695 DOI: 10.1371/journal.pone.0118675] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2014] [Accepted: 01/22/2015] [Indexed: 11/19/2022] Open
Abstract
Objectives The 2013 World Health Organization Status Report on Road Safety estimated that approximately 1.24 million deaths occur annually due to road traffic crashes with most of the burden falling on low- and middle-income countries. The objective of this research is to study the prevalence of road traffic crashes in Mekelle, Tigray, Northern Ethiopia and to identify risk factors with the ultimate goal of informing prevention activities and policies. Methods This study used a cross-sectional design to measure the prevalence and factors associated with road traffic crashes among 4-wheeled minibus (n = 130) and 3-wheeled Bajaj (n = 582) taxi drivers in Mekelle, Ethiopia. Bivariate and multivariate logistic regression were used to evaluate the association between risk factors and drivers’ involvement in a road traffic crash within the 3 years prior to the survey. Findings Among the 712 taxi drivers, 26.4% (n = 188) of them reported involvement in a road traffic crash within the past 3 years. Drivers who listened to mass media had decreased likelihood of road traffic crash involvement (AOR = 0.51, 0.33–0.78), while speedy driving (AOR = 4.57, 3.05–7.44), receipt of a prior traffic punishment (AOR = 4.57, 2.67–7.85), and driving a mechanically faulty taxi (AOR = 4.91, 2.81–8.61) were strongly associated with road traffic crash involvement. Receiving mobile phone calls while driving (AOR = 1.91, 1.24–2.92) and history of alcohol use (AOR = 1.51, 1.00–2.28) were also associated with higher odds of road traffic crash involvement. Conclusion The results of this study show that taxi drivers in Mekelle habitually place themselves at increased risk of road traffic crashes by violating traffic laws, especially related to speedy driving, mobile phone use, and taxi maintenance. This research can be used to support re-evaluation of the type, severity, and enforcement of traffic violation penalties.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2014; 11:10269-91. [PMID: 25279544 PMCID: PMC4210978 DOI: 10.3390/ijerph111010269] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/29/2014] [Revised: 09/19/2014] [Accepted: 09/23/2014] [Indexed: 11/20/2022]
Abstract
Decreasing traffic speeds increases the amount of time drivers have to react to road hazards, potentially averting collisions, and makes crashes that do happen less severe. Boston’s regional planning agency, the Metropolitan Area Planning Council (MAPC), in partnership with the Massachusetts Department of Public Health (MDPH), conducted a Health Impact Assessment (HIA) that examined the potential health impacts of a proposed bill in the state legislature to lower the default speed limits on local roads from 30 miles per hour (mph) to 25 mph. The aim was to reduce vehicle speeds on local roads to a limit that is safer for pedestrians, cyclists, and children. The passage of this proposed legislation could have had far-reaching and potentially important public health impacts. Lower default speed limits may prevent around 18 fatalities and 1200 serious injuries to motorists, cyclists and pedestrians each year, as well as promote active transportation by making local roads feel more hospitable to cyclists and pedestrians. While a lower speed limit would increase congestion and slightly worsen air quality, the benefits outweigh the costs from both a health and economic perspective and would save the state approximately $62 million annually from prevented fatalities and injuries.

Abstract
El objetivo fue identificar y cuantificar la asociación entre la intensidad de exposición (km/año recorridos), la accidentalidad y sus factores asociados en universitarios de Guatemala. Se realizó un estudio trasversal durante el curso 2010-2011, sobre una muestra de 1.016 conductores, quienes cumplimentaron un cuestionario autoadministrado que valoraba: patrones de movilidad, uso de dispositivos de seguridad, estilos de conducción y accidentalidad. Se obtuvieron asociaciones positivas entre la intensidad de exposición y la mayor implicación en circunstancias de riesgo al volante (coeficiente de regresión ajustado de 3,25, IC95%: 2,23-4,27, para las mayores exposiciones). Tanto una mayor implicación en tales circunstancias, como una mayor edad, fueron las variables más fuertemente asociadas con la mayor accidentalidad. Pese a que la intensidad de exposición se asocia positivamente con una mayor accidentalidad, se constató que la mayor parte de dicha asociación está mediada por una mayor implicación en circunstancias de riesgo al volante.

Abstract
OBJECTIVES To investigate the recent epidemiological patterns and costs of road traffic casualties (RTCs) in Strathclyde, Scotland. STUDY DESIGN Retrospective record-linkage epidemiological study using routine data sources. METHODS A linked police-hospital database was analysed to describe the epidemiology of RTCs from 2004 to 2009. Using UK government methodology, the costs of road casualties to the National Health Service (NHS) and society were assessed. RESULTS RTC rates declined over the study period. Males were at higher risk than females as were those residing in more socially deprived addresses. The estimated costs of RTCs in Strathclyde amounted to £400 million annually. Of this, around one twentieth (£20 million per year), was attributable to direct NHS costs. CONCLUSIONS Road casualties remain a major public health threat in Strathclyde, and contribute to health inequalities. RTC costs to society amount to almost a tenth of NHS revenue expenditure. Cost-effective road safety measures should be deployed more widely.

Abstract
PURPOSE To estimate and compare reliability of traffic mortality data of the police and the healthcare sector in Arkhangelsk, Russia. METHODS The study matched traffic mortality data of the police and the regional healthcare statistics centre for the period from 2005 to 2010. Individual investigations of unmatched cases were performed, and the underlying causes of the non-matches were established. The obtained distribution of non-matches by causes served as basis for estimating the true numbers of traffic fatalities in the two sources, in appliance with corresponding fatality definitions and registration rules. A data accuracy index (DAI) was calculated for each source by using an adapted version of the formula for calculating accuracy of a diagnostic test. This was used as a measure for data reliability. Time trends in annual DAIs were estimated for each source by χ(2)-test for linear trend. RESULTS During the 6-year period, the police and the healthcare statistics centre registered 217 and 237 traffic fatalities in Arkhangelsk, respectively. Matching of data from the two sources resulted in 162 matched cases, 55 unmatched cases in the police data, and 75 unmatched cases in the healthcare data. More than a half (56%) of the non-matches were attributed to incompatibility of the definitions in the two data registration systems; 39% were attributed to failures in the healthcare data. Other non-matches were due to scarce identifying information (2%) or were not classifiable (2%). None of the non-matches were clearly attributable to failures in the police data. The 6-year DAI was 98% for the police data and 80% for the healthcare data. The DAI for the police data was stable over 2005-2010 (ranging from 96% to 100%). The DAI for the healthcare data increased from 66% in 2005 to 98% in 2010 (Ptrend<0.001). CONCLUSION The findings suggest that traffic mortality data of the police were more reliable, compared to the healthcare data. However, reliability of the healthcare data was improving during the study period.

Abstract
AIMS AND OBJECTIVES This paper will focus on the key concepts behind record linkage and describe how probability matching of Scottish health records can be used for national health research. BACKGROUND Record linkage can bring together two or more records relating to the same individual. This allows information from multiple sources to be joined together to produce richer data sets for research purposes and has wide applicability in public health and epidemiological research. The probability matching techniques underpinning record linkage bring together records on a patient basis using key identifying information on each record. Scotland has a strong track record for performing linkage for research purposes owing to routinely collected and well-maintained national administrative health data sets, the emergence of the Scottish record linkage system and organisations like the Information Services Division of NHS National Services Scotland who centrally hold permanently linked patient-based databases. Design. A record linkage retrospective population cohort study is described within this paper. METHODS The paper will describe current linkage methodology before discussing typical applications in the setting of Information Services Division and focusing on a particular linkage study investigating rates and risk factors for gastroschisis. RESULTS Conclusions from the gastroschisis study are typical of the types of important findings drawn from analysing linked health data. CONCLUSIONS Scotland's good track record for linking records for health research is evidenced by the high volume of research projects, publications and findings resulting from probability matching of national health data. Relevance to clinical practice. Record linkage allows information relating to the same person held across different data sources to be brought together. Probabilistic record linkage can overcome data quality issues, producing accurate matches. This allows linked, analysable, patient-based databases, capable of answering complex research questions, to be produced from several data sources with wide applications in the field of health research.

Abstract
OBJECTIVES Road traffic injuries are a widespread problem and are very difficult to prevent. The purpose of this study was to verify whether intensive versus basic road safety education programs are associated with different incidence and severity of nonfatal road injuries. METHOD The study had an ecological design and involved Local Health Authority One (LHA1) in Salerno, Italy, which includes 20 municipalities. Data on nonfatal road injuries occurring in the periods June to August 2003 and June to August 2008 were obtained from trained operators through the information system of the emergency department. All 20 municipalities received a basic community road safety education program (publicity campaign using bill-posting, brochures, mass media communication with press conferences, articles in local papers, radio and television interviews, and a dedicated LHA1 web site), and 12 municipalities also received an intensive education campaign (in secondary schools, community conferences, and activities organized by police and firefighters). The incidence and severity of nonfatal road traffic injuries were compared between June to August 2003 (before the campaign) and June to August 2008. RESULTS The total number of injuries in all 20 municipalities in 2003 and 2008 was 907 and 755, respectively. The incidence of injuries decreased in the study period both in the 8 municipalities where only the basic campaign was run (difference in incidence = -0.4; P = .053) and in the 12 municipalities where the intensive campaign was implemented (difference in incidence = -0.5; P < .001); focusing on severity, the incidence of severe injuries decreased or remained the same in the study period in the 2 studied group. DISCUSSION The results are coherent with other European studies and show that an overall downward trend exists but is presumably not a direct consequence of road safety education. This does not mean that such campaigns are useless (they are important to raise awareness) but that they should be supplemented with complementary activities in order to be really effective.

Abstract
INTRODUCTION In Saudi Arabia, road traffic accidents (RTA) are becoming a serious public health problem. Police reports are designed for legal purposes with very little information on the health consequences. Also, health system data include detailed health information, but not related or linked to the data obtained police reports. Examining the consistency of these sources is vital to build an accurate surveillance system that can track the risk factors and the health consequences, as well as establishing and evaluating prevention interventions. OBJECTIVES This study is intended to: ▪ Examine the consistency of health -registration data with the data gathered by the traffic police department.▪ Elucidate the magnitude, risk factors and outcome of RTI in Qassim region of Saudi Arabia,▪ Compare the pattern of accidents in Qassim with those at different regions of the Kingdom. METHODOLOGY Health care information was collected on visits of victims of road traffic accidents to emergency and outpatients' departments of the major hospitals in Qassim region during the year 2010. The information included the patients' demographics, and clinical characteristics. Traffic Police Department information was also collected on all accidents that occurred in the study region. A Questionnaire was also developed and pilot tested to collect data from a random sample of population attending hospital outpatient and Primary Health Care clinics. Data included previous involvement in road traffic accident, and information about any injury; fatality or disability due to these RTI. RESULTS During the study period, road traffic death rate based on death registration data was almost twice as high as the rate reported by the police (P < 0.05). There was also a significant decline of 27% according to police-reported data during the study period, as opposed to a non-significant increase of 8% according to health registration data during the same period. Population Survey Information showed the overall age-sex-adjusted rate for non-fatal RTI was 20.7 (95% CI, 20.0 - 21.3)/100 persons/year. The rate for non-fatal RTI is higher in the 10-19 years age group (17.3%). Males had twice or more incidence rate for RTI requiring recovery period of ≤ 7 days as compared with females, however, RTI incidence for recovery period of >7 days is more than twice in females.. Also a total of 12 deaths due to RTI were reported in 5-49 years age group in the last 3 years, representing an estimated annual RTI mortality rate of 35.4/100,000 (95% CI 16.6 - 57.8). A total of 11 participants reported RTI related disability in the last 3 years representing an estimated annual RTI disability rate of 34.1/100,000 population (95% CI 11.4 - 55.7). Reports of the Traffic Police Department showed that 18623 accidents occurred throughout the year 2010. These accidents involved 23178 persons, and resulted in the injury of 2025 people and the deaths of 369. In contrast, the health system reports showed that 4232 people had been injured and 1054 had died. Comparison with local & Arab Rates showed that Qassim is among the highest 5 regions in the kingdom regarding the number of RTA Saudi Arabia is also having a very high level of road traffic accidents and fatalities compared to other Arab countries. CONCLUSION RTI are responsible for significant loss of life, disability and injury in Qassim population and in Saudi Arabia. The inconsistency between police-reported data and health system data strongly suggests that active efforts to audit and monitor data quality are clearly necessary.

Abstract
Linking hospital discharge and police traffic crash records has been used to provide information on causes and outcomes for hospitalised traffic crash cases. Motorcyclists are particularly vulnerable to injury in a traffic crash, but no published linkage studies have reported in detail on this road user group. The present study examined motorcycle traffic crash injury cases in New Zealand in 2000-2004 by probabilistically linking national hospital discharge records with police traffic crash reports. Injury cases had to have spent at least one night in hospital before being discharged and were defined as serious or moderate based on their International Classification of Disease Injury Severity Scores (ICISS). Despite a robust linkage process, only 46% of cases could be linked to a police record; 60% of the serious injuries and 41% of the moderate. The low linkage was most likely due to under-reporting of crashes to or by the police. While moderate injury cases were expected to be under-reported, the level of under-reporting of cases with serious threat-to-life injuries is concerning. To assess whether the linked dataset could provide valid information on the crash circumstances and injury outcomes of hospitalised motorcycle crash cases, the characteristics of the linked and unlinked hospital discharge cases were compared using chi-square tests and multivariate logistic regression. Serious injury cases were less likely to be linked if only one vehicle was involved, or the injured riders and passengers were younger than 20 years or spent less than one week in hospital. For moderate injury cases, there were also differences in linkage by injured body region and crash month. While these discrepancies need to taken into consideration when interpreting results, the linked hospital-police dataset has the potential to provide insights into motorcycle crash circumstances and outcomes not otherwise obtainable.

Abstract
OBJECTIVE Road traffic injury (RTI) has become one of the leading causes of deaths in China, yet numbers on road traffic deaths are often inconsistent. This study sought to systematically review 4 national-level data sources that can be used to estimate burdens of RTI, including mortality, injury, and crashes in China. METHODS We conducted structured literature reviews in PubMed, using combined key words of injury or fatality or injury surveillance and traffic and China in order to identify relevant studies (in both English and Chinese) and data sources. We also conducted interviews and hosted seminars with key researchers from the Chinese Center for Disease Control and Prevention (Chinese CDC) to identify potential useful data sources for injury surveillance. We then extracted key information from publicly available reports of each data source. RESULTS Four national-level data sources were reviewed and compared: Ministry of Health-Vital Registration (MOH-VR) System, Chinese CDC-Disease Surveillance Points (DSP), Chinese CDC-National Injury Surveillance System (NISS), and police reports. Together they provide a complementary yet somewhat contradictory epidemiological profile of RTIs in China. Estimates on road traffic fatalities obtained from MOH-VR and police reports are often used by researchers and policymakers, whereas DSP and NISS, both with great merits, have virtually not been used for RTI research. Despite the well-documented problems of underreported deaths with both MOH-VR and DSP, estimated road traffic deaths from both systems were 3 times those reported by the police. CONCLUSIONS As the foundation of injury prevention, national-level data sources and surveillance systems were reviewed in the study. Existing data infrastructures present the Chinese government a great opportunity to strengthen and integrate existing surveillance systems to better track road traffic injury and fatality and identify the population at risk.

[PMID: 21244666 PMCID: PMC3033330 DOI: 10.1186/1478-7954-9-2] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2010] [Accepted: 01/18/2011] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND This study quantifies the burden of road traffic injuries (RTIs) in Thailand in 2004, incorporating new Thai data on mortality and the frequency and severity of long-term disability. METHODS We quantified the uncertainty around national RTI mortality estimates based on a verbal autopsy study that was conducted to correct for the large proportion of ill-defined deaths in the vital registration system. The number of nonfatal RTI victims was estimated using hospital and survey data. We used the proportion and severity of long-term disabilities from a recent Thai study, instead of the standard Global Burden of Disease assumptions, to calculate the burden due to long-term disability. To evaluate changes over time, we also calculated the burden of RTIs in 2004 using the method and assumptions used in 1999, when standard Global Burden of Disease assumptions were used. RESULTS The total loss of disability-adjusted life years due to RTIs was 673,000 (95% uncertainty interval [UI]: 546,000-881,000). Mortality contributed 88% of this burden. The use of local data led to a significantly higher estimate of the burden of long-term disability due to RTIs (74,000 DALYs [95% UI: 55,400-88,500] vs. 43,000 [UI: 42,700-43,600]) using standard Global Burden of Disease methods. However, this difference constituted only a small proportion of the total burden. CONCLUSIONS The burden of RTIs in 2004 remained at the same high level as in 1999. The use of local data on the long-term health consequences of RTIs enabled an estimate of this burden and its uncertainty that is likely to be more valid.

Hu G, Baker T, Baker SP. Comparing road traffic mortality rates from police-reported data and death registration data in China. Bull World Health Organ 2010; 89:41-5. [PMID: 21346889 DOI: 10.2471/blt.10.080317] [Citation(s) in RCA: 58] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2010] [Revised: 08/27/2010] [Accepted: 09/03/2010] [Indexed: 11/27/2022] Open
Abstract
OBJECTIVE To compare death rates from road traffic injuries in China in 2002-2007 when derived from police-reported data versus death registration data. METHODS In China, police-recorded data are obtained from police records by means of a standardized, closed-ended data collection form; these data are published in the China statistical yearbook of communication and transportation. Official death registration data, on the other hand, are obtained from death certificates completed by physicians and are published in the China health statistics yearbook. We searched both sources for data on road traffic deaths in 2002-2007, used the χ(2) test to compare the mortality rates obtained, and performed linear regression to look for statistically significant trends in road traffic mortality over the period. FINDINGS For 2002-2007, the rate of death from road traffic injuries based on death registration data was about twice as high as the rate reported by the police. Linear regression showed a significant decrease of 27% (95% confidence interval, CI: 35-19) in the death rate over the period according to police sources but no significant change according to death registration data. CONCLUSION The widely-cited recent drop in road traffic mortality in China, based on police-reported data, may not reflect a genuine decrease. The quality of the data obtained from police reports, which drives decision-making by the Government of China and international organizations, needs to be investigated, monitored and improved.
