Effectiveness of speed cameras in preventing road traffic collisions and related casualties: systematic review.

Abstract Objectives To assess whether speed cameras reduce road traffic collisions and related casualties. Design Systematic review. Data sources Cochrane Injuries Group Specialised Register, Cochrane Central Register of Controlled Trials, Medline, Embase, Social Science Citation Index, TRANSPORT database, ZETOC, the internet (including websites of road safety and motoring organisations), and contact with key individuals and organisations. Main outcome measures Road traffic collisions, injuries, and deaths. Inclusion criteria Controlled trials and observational studies assessing the impact of fixed or mobile speed cameras on any of the selected outcomes. Results 14 observational studies met the inclusion criteria; no randomised controlled trials were found. Most studies were before-after studies without controls (n = 8). All but one of the studies showed effectiveness of cameras up to three years or less after their introduction; one study showed sustained longer term effects (4.6 years after introduction). Reductions in outcomes across studies ranged from 5% to 69% for collisions, 12% to 65% for injuries, and 17% to 71% for deaths in the immediate vicinity of camera sites. The reductions over wider geographical areas were of a similar order of magnitude. Conclusions Existing research consistently shows that speed cameras are an effective intervention in reducing road traffic collisions and related casualties. The level of evidence is relatively poor, however, as most studies did not have satisfactory comparison groups or adequate control for potential confounders. Controlled introduction of speed cameras with careful data collection may offer improved evidence of their effectiveness in the future.

Understanding the Processes of Translation and Transliteration in Qualitative Research

There has been growing interest in the use of qualitative methods in health research amongst health and social care professionals. Good qualitative cross-cultural research analysis is not an easy task as it involves knowledge of different approaches, techniques and command of the appropriate languages. This article aims to discuss and explore some of the key processes and concepts involved in conducting translation and transliteration of qualitative research.

Supported employment for persons with mental illness: systematic review of the effectiveness of individual placement and support in the UK

Background. High levels of unemployment among persons with mental illness are a significant social disability. The individual placement and support (IPS) model of vocational support has been shown to be effective in establishing persons with mental health problems back into competitive employment in North America. Evidence outside North America is more limited. Aim. To examine the evidence for the effectiveness of the IPS model of supported employment within the United Kingdom. Methods. Systematic review of studies of the effectiveness of IPS conducted principally in the United Kingdom. Results. The evidence base was small. Overall quality of evidence was fair. There is evidence that interventions with high fidelity to the IPS model increase the proportion of patients engaged in work or education/training over the short- to medium-term (6–18 months follow-up). Conclusions. More research is needed to improve the evidence base in relation to IPS within a UK context. Evaluation should focus on both the nature and quality of the employment gained, patient and service factors.

Health impacts of exposure to second hand smoke (SHS) amongst a highly exposed workforce: survey of London casino workers

BackgroundCasino workers are exposed to high levels of secondhand smoke (SHS) at work, yet remain at risk of being excluded from smoke-free legislation around the world. If the prime motivation for smoke-free legislation is the protection of workers, then a workforce experiencing ill-health associated with SHS exposure should not be excluded from legislation. This study aimed to determine the prevalence of respiratory and sensory irritation symptoms among a sample of casino workers, to identify any association between the reporting of symptoms and exposure to SHS at work, and to compare the prevalence of symptoms with that in other workers exposed to SHS.MethodsA postal questionnaire survey of 1568 casino workers in London. Using multivariate analysis we identified predictors of respiratory and sensory irritation symptoms.Results559 workers responded to the questionnaire (response of 36%). 91% of casino workers reported the presence of one or more sensory irritation symptoms in the previous four weeks, while the figure was 84% for respiratory symptoms. The presence of one or more sensory irritation symptoms was most strongly associated with reporting the highest exposure to SHS at work (OR 3.26; 1.72, 6.16). This was also true for reporting the presence of one or more respiratory irritation symptoms (OR 2.24; 1.34, 3.74). Prevalence of irritation symptoms in the casino workers was in general appreciably higher than that reported in studies of bar workers.ConclusionOur research supports the need for comprehensive smoke-free legislation around the world, covering all indoor workplaces including casinos.

Music making for health, well-being and behaviour change in youth justice settings: a systematic review

Youth justice is an important public health issue. There is growing recognition of the need to adopt effective, evidence-based strategies for working with young offenders. Music interventions may be particularly well suited to addressing risk factors in young people and reducing juvenile crime. This systematic review of international research seeks to contribute to the evidence base on the impact of music making on the health, well-being and behaviour of young offenders and those considered at risk of offending. It examines outcomes of music making identified in quantitative research and discusses theories from qualitative research that might help to understand the impact of music making in youth justice settings.

Rhetoric or reality? A systematic review of the impact of participatory approaches by UK public health units on health and social outcomes

BACKGROUND There has been a philosophical commitment to participation in public health since the 1970s. UK policy rhetoric on participation in public health has been particularly marked since 1997. It is less clear that participatory approaches have been pursued by UK public health units in practice. METHODS A systematic review was undertaken of all studies using any recognized research methodology from 1974 to 2007 reporting on health and social outcomes of participatory approaches by UK public health units. Seventeen electronic databases were searched and inclusion/exclusion criteria and quality appraisal criteria applied. RESULTS Five thousand and four hundred and fifty-one references were identified, reduced to 2155 once duplicates were removed. Only eight papers covering seven studies were relevant and included in the analysis. Only two studies met more than half of the relevant quality appraisal criteria. The studies fell into two distinct groups: four used qualitative methods to illustrate the complexities of effective community participation; three claimed success for their participative initiative without providing adequate evidence to substantiate such claims. CONCLUSIONS This systematic review demonstrates that there is very little evidence in the peer-reviewed literature of participatory approaches by UK public health units or of such approaches having any noteworthy impact on health and social outcomes.

Decentralization and district health services in Nepal: understanding the views of service users and service providers.

BACKGROUND Within the decentralization framework of Government, the Ministry of Health (MoH) Nepal initiated the decentralization of primary care services closer to citizens. This paper aims to examine and understand the effect of decentralization at the district health service from the perspectives of service users and providers. METHODS Using non-probability purposive sampling, we conducted a series of in-depth interviews and focus group discussions in four primary health care institutions with service users, providers and other stakeholders. QSRNVivo7 software was used to analyse and categorize the data under emerging themes. RESULTS Decentralization was positively associated with increased service access and utilization and improved service delivery. The study also revealed areas of concern and possible improvement and identified the barriers to implementing these improvements. Problems described included three main areas: functions, functionaries and funding. CONCLUSION Both service users and providers convey a generally positive message about the health sector decentralization. The active involvement of service users, providers, policy-makers in the process of decentralization and clear national and local policy agendas may bring positive changes in district health services.

Evaluating social and behavioural impacts of English smoke-free legislation in different ethnic and age groups: implications for reducing smoking-related health inequalities

Objective To explore social and behavioural impacts of English smoke-free legislation (SFL) in different ethnic groups. Design A longitudinal, qualitative panel study of smokers using in-depth interviews conducted before and after introduction of SFL. Participants A purposive sample of 32 smokers selected from three ethnic groups in deprived London neighbourhoods with approximately equal numbers of younger and older, male and female respondents. Results SFL has had positive impacts with half smoking less and three quitting. Although there were no apparent differences in smoking and quitting behaviours between groups, there were notable differences in the social impacts of SFL. The greatest negative impacts were in smokers over 60 years, potentially increasing their social isolation, and on young Somali women whose smoking was driven more underground. In contrast, most other young adult smokers felt relatively unaffected by SFL, describing unexpected social benefits. Although there was high compliance, reports of illegal smoking were more frequent among young, ethnic minority smokers, with descriptions of venues involved suggesting they are ethnically distinct and well hidden. Half of respondents reported stopping smoking in their own homes after SFL, but almost all were Somali or Turkish. White respondents tended to report increases in home smoking. Discussion Although our study suggests that SFL can lead to reductions in tobacco consumption, it also shows that impacts vary by ethnicity, age and sex. This study highlights the importance of understanding the meaning of smoking in different social contexts so future tobacco control interventions can be developed to reduce health and social inequalities.

Promoting integration of the health and built environment agendas through a workforce development initiative

There is a renewed and growing recognition of the links between public health and the built environment, which has underlined the need for improved joint working between public health and built environment professionals. However, currently there is little engagement between these two sectors. This paper outlines a workforce development initiative that aims to increase capacity for such joint working, through shared learning and reflection between professionals from the built environment sector and those from the specialist public health workforce. This paper demonstrates how shared learning through facilitated learning sets and other activities has identified issues that both hinder and potentially help the greater integration of health into built environment thinking. It documents a number of responses to the issues that have arisen, as well as suggesting ways forward and future work that can help to bring public health and built environment professionals closer together for the benefit of society.

Understanding the social context of fatal road traffic collisions among young people: a qualitative analysis of narrative text in coroners' records

BackgroundDeaths and injuries on the road remain a major cause of premature death among young people across the world. Routinely collected data usually focuses on the mechanism of road traffic collisions and basic demographic data of those involved. This study aimed to supplement these routine sources with a thematic analysis of narrative text contained in coroners’ records, to explore the wider social context in which collisions occur.MethodsThematic analysis of narrative text from Coroners’ records, retrieved from thirty-four fatalities among young people (16–24 year olds) occurring as a result of thirty road traffic collisions in a rural county in the south of England over the period 2005–2010.ResultsSix key themes emerged: social driving, driving experience, interest in motor vehicles, driving behaviour, perception of driving ability, and emotional distress. Social driving (defined as a group of related behaviours including: driving as a social event in itself (i.e. without a pre-specified destination); driving to or from a social event; driving with accompanying passengers; driving late at night; driving where alcohol or drugs were a feature of the journey) was identified as a common feature across cases.ConclusionsAnalysis of the wider social context in which road traffic collisions occur in young people can provide important information for understanding why collisions happen and developing targeted interventions to prevent them. It can complement routinely collected data, which often focuses on events immediately preceding a collision. Qualitative analysis of narrative text in coroner’s records may provide a way of providing this type of information. These findings provide additional support for the case for Graduated Driver Licensing programmes to reduce collisions involving young people, and also suggest that road safety interventions need to take a more community development approach, recognising the importance of social context and focusing on social networks of young people.
