A new approach to managing work-related road traffic injury: The development of a health investment framework

OBJECTIVE

Statistics indicate that employees commuting or traveling as part of their work are overrepresented in workplace injury and death. Despite this, many organizations are unaware of the factors within their organizations that are likely to influence potential reductions in work-related road traffic injury.

METHODS

This article presents a multilevel conceptual framework that identifies health investment as the central feature in reducing work-related road traffic injury. Within this framework, we explore factors operating at the individual driver, workgroup supervisor, and organizational senior management levels that create a mutually reinforcing system of safety.

RESULTS

The health investment framework identifies key factors at the senior manager, supervisor, and driver levels to cultivating a safe working environment. These factors are high-performance workplace systems, leader-member exchange and autonomy, trust and empowerment, respectively. The framework demonstrates the important interactions between these factors and how they create a self-sustaining organizational safety system.

CONCLUSIONS

The framework aims to provide insight into the future development of interventions that are strategically aligned with the organization and target elements that facilitate and enhance driver safety and ultimately reduce work-related road traffic injury and death.

Do management practices support or constrain safe driving behaviour? A multi-level investigation in a sample of occupational drivers

It has been estimated that one-third of all work-related deaths occur while driving for work-related purposes. Despite this, many organisations are unaware of the practices, beyond those that identify and control the impact of unforeseen events (i.e., risk management), that predispose drivers to risk. This study addresses the issue by identifying the management practices operationalised as, High Performance Workplace Systems (HPWS) that influence safe driver behaviour. The study also explores the value given to safety by senior level management as a moderator of the relationship between HPWS practices and driver behaviour. Each factor was tested within a two level hierarchical model consisting of 911 drivers, nested within 161 supervisors and 83 organisations. The findings highight that under conditions of high investment in job and work design, communication and selection practices, drivers reported poorer driving behaviour. An interaction effect also demonstrated that under conditions of high investment in remuneration, drivers reported safer behaviour, but only when they perceived that managers valued and prioritised safety. The findings challenge current thinking in the management of workplace road safety.

A comprehensive conceptual framework for road safety strategies

Road safety strategies (generally called Strategic Highway Safety Plans in the USA) provide essential guidance for actions to improve road safety, but often lack a conceptual framework that is comprehensive, systems theory based, and underpinned by evidence from research and practice. This paper aims to incorporate all components, policy tools by which they are changed, and the general interactions between them. A framework of nine mutually interacting components that contribute to crashes and ten generic policy tools which can be applied to reduce the outcomes of these crashes was developed and used to assess 58 road safety strategies from 22 countries across 15 years. The work identifies the policy tools that are most and least widely applied to components, highlighting the potential for improvements to any individual road safety strategy, and the potential strengths and weaknesses of road safety strategies in general. The framework also provides guidance for the development of new road safety strategies, identifying potential consequences of policy tool based measures with regard to exposure and risk, useful for both mobility and safety objectives.

Time pressure and regulations on hospital-in-the-home (HITH) nurses: An on-the-road study

This study investigated both causal factors and consequences of time pressure in hospital-in-the-home (HITH) nurses. These nurses may experience additional stress from the time pressure they encounter while driving to patients' homes, which may result in greater risk taking while driving. From observation in natural settings, data related to the nurses' driving behaviours and emotions were collected and analysed statistically; semi-directed interviews with the nurses were analysed qualitatively. The results suggest that objective time constraints alone do not necessarily elicit subjective time pressure. The challenges and uncertainty associated with healthcare and the driving period contribute to the emergence of this time pressure, which has a negative impact on both the nurses' driving and their emotions. Finally, the study focuses on anticipated and in situ regulations. These findings provide guidelines for organizational and technical solutions allowing the reduction of time pressure among HITH nurses.

21st century trucking: A trajectory for ergonomics and road freight

Over the past decade there has been significant pressure to minimise emissions and safety risks related to commercial driving. This pressure to meet the triple bottom line of cost, environment, and society has often resulted in the rapid application of vehicle technologies designed to mitigate undesired effects. Often the cognitive and behavioural effects of technologies on the commercial driver have not received in-depth analysis to determine comprehensive viability. As such, this paper aims to identify a timescale for implementation for future technologies for UK road freight, and likely associated human factors issues, improving upon the currently employed 'trial-and-error' approach to implementation which may carry high economic, environmental, safety-related risk. Thought experiments are carried out to broadly explore these future systems. Furthermore, this work aims to examine whether technology alone will be enough to meet future CO2 reduction targets, and assess the role of behavioural and systems interventions for future research.

Initial development of a practical safety audit tool to assess fleet safety management practices

Work-related vehicle crashes are a common cause of occupational injury. Yet, there are few studies that investigate management practices used for light vehicle fleets (i.e. vehicles less than 4.5 tonnes). One of the impediments to obtaining and sharing information on effective fleet safety management is the lack of an evidence-based, standardised measurement tool. This article describes the initial development of an audit tool to assess fleet safety management practices in light vehicle fleets. The audit tool was developed by triangulating information from a review of the literature on fleet safety management practices and from semi-structured interviews with 15 fleet managers and 21 fleet drivers. A preliminary useability assessment was conducted with 5 organisations. The audit tool assesses the management of fleet safety against five core categories: (1) management, systems and processes; (2) monitoring and assessment; (3) employee recruitment, training and education; (4) vehicle technology, selection and maintenance; and (5) vehicle journeys. Each of these core categories has between 1 and 3 sub-categories. Organisations are rated at one of 4 levels on each sub-category. The fleet safety management audit tool is designed to identify the extent to which fleet safety is managed in an organisation against best practice. It is intended that the audit tool be used to conduct audits within an organisation to provide an indicator of progress in managing fleet safety and to consistently benchmark performance against other organisations. Application of the tool by fleet safety researchers is now needed to inform its further development and refinement and to permit psychometric evaluation.

Stakeholder perspectives on managing the occupational health of UK business drivers: a qualitative approach

Musculoskeletal disorders are one of the leading causes of work related ill health and sickness absence. Those who drive as part of their job may be at particular risk, with evidence suggesting that prolonged exposure to driving is associated with increased absence from work due to low back pain. Business drivers often work away from a traditional office environment. Such mobile working may pose greater risks to occupational health due to increased ergonomic risks, for example working from the car, longer working hours and a lack of concern amongst drivers about health and safety. It has been suggested that occupational health practices have not adapted to meet the needs of peripatetic workers. The current study explored how occupational health services are delivered to business drivers. Semi-structured interviews were carried out with a sample of 31 stakeholders in 4 organisations. Respondents included, health and safety professionals, occupational health nurses, fleet managers and high mileage business drivers. The interviews were transcribed and analysed using 'Template Analysis'. The data revealed that, within these organisations, the provision of occupational health services was often fragmented and drivers and other key stakeholders were often unaware of the existing systems within their organisations. The peripatetic nature of business drivers meant that they were difficult for occupational health teams to reach. The paper concludes by presenting recommendations for occupational health professionals and researchers engaged with improving the health of peripatetic workers, namely that occupational health policies should be integrated in company strategy and widely disseminated to drivers and those with responsibility for managing their occupational health provision.

The effect of daily-activity patterns on crash involvement

The main purpose of this study is to analyze the effect of daily-activity and travel patterns on the risk of crash involvement. To this end, we develop a model that integrates daily-activity and travel choices in a single framework, recognizing that these variables affect the risk of crashes. This model can therefore provide predictions of the expected changes in risk levels from the implementation of measures that affect the daily-activity patterns and the socio-economic characteristics of the population. The empirical analysis makes use of data collected during a household survey that includes crash information and trip diaries. The model is applied in a case study of an Arab town in Israel to analyze various transportation policies. The results of this research show that in addition to individuals' demographic and socio-economic characteristics, their daily-activity and travel patterns also have an impact on the risk of being involved in car crashes. The case study showed the potential of this framework for analyzing the effect of various social and transportation policies on road safety. To the best of our knowledge, this is the first time such relationships have been tested by using a disaggregate model and the first time activity-based models have been used to analyze exposure to the risk of road crashes.

Risk factors for worker injury and death from occupational light vehicles crashes in New South Wales (Australia)

BACKGROUND/AIM

To identify risk and protective factors for crash casualty outcomes in occupational light vehicles (OLV), a previously under-recognized work context for injuries and fatalities.

METHODS

A register-based study was conducted using linked vehicle crash and registration data (n = 13,491) for the Australian state of New South Wales. Univariate and multivariate analyses were undertaken to assess the relationship between casualty outcomes and variables drawn from four domains of potential determinants of severity: user, vehicle, road, and work organization factors.

RESULTS

Nineteen percent of OLV crashes had OLV-user casualties (n = 2,506) and 1% fatalities (n = 34). Adjusted casualty risk factors included tired driver (OR 2.1, 95% CI 1.5-2.7), no seat belt use (OR 1.8, 95% CI 1.4-2.3), and excessive speed (OR 1.4, 95% CI 1.2-1.6). Adjusted fatality risk factors were no seat belt (OR 12.9, 95% CI 4.9-34.3) and high-speed zone crash (OR 5.0, 95% CI 2.1-12.3).

CONCLUSIONS

OLV users are at risk from both recognized road risks and hazards specific to OLV use. Findings suggest that risk reduction could be improved by the use of safer vehicles, fatigue management, and journey planning.

Nonfatal work-related motor vehicle injuries treated in emergency departments in the United States, 1998-2002

BACKGROUND

Current data on nonfatal work-related motor vehicle injuries are limited and fragmented, often excluding government workers, self-employed workers, and workers on small farms. This study seeks to bridge the present data gap by providing a national profile of nonfatal work-related motor vehicle injuries across all industries and occupations.

METHODS

Study subjects were people who suffered nonfatal work-related motor vehicle injuries and were treated in a hospital emergency department in the United States. Subjects were identified from a stratified probability sample of emergency departments. National estimates and rates were computed.

RESULTS

From 1998 to 2002, the average annual rate of nonfatal work-related motor vehicle injuries was 7 injuries per 10,000 full-time equivalents. The rate was three times higher in men than in women. The rates were higher in workers 15-19 years of age and in workers 70 years or older. Justice, public order, and safety workers had the largest number of injuries, and taxicab service employees had the highest injury rate of all industries. Truck drivers had the largest number of injuries, and police and detectives, public service employees had the highest injury rate of all occupations.

CONCLUSION

Future efforts need to develop and enhance the use of surveillance information at the federal and state level for work-related nonfatal motor vehicle injuries. Prevention efforts need to address occupational motor vehicle safety for both commercial truck/bus drivers and workers who are not commercial drivers but who drive light motor vehicles on the job.
