Abstract
The central question of our study is which determinants drive smoke alarm ownership and intention to purchase one, and whether we can increase smoke alarm ownership by addressing these determinants in a communication-based intervention. We first made an inventory of possible determinants for smoke alarm prevention by consulting prominent prevention behavior theories protection motivation theory and Health Belief Model and other relevant literature. We expanded this list of determinants based on interviews (n = 15) and used survey data representative for the Netherlands to decide to focus on smoke alarm ownership (rather than installation or maintenance). We then tested the determinants of smoke alarm ownership and buying intention in a survey (n = 622). Based on these results, we ran an A/B test (n = 310) of two messages to stimulate smoke alarm ownership: one emphasized the determinants we found to be strong predictors in the survey (know-how, social norm, annoyance) and one emphasized typical determinants that are often addressed in campaigns but were poor predictors in the survey (vulnerability, severity, benefits). Results showed that the message based on the strong determinants resulted in a significant increase in smoke alarm ownership (9.1%) compared to the control group (0.9%; p = 0.027), while the message using the typical determinants did not lead to significant effects. Taken together, our results give a promising direction for interventions to increase smoke alarm ownership, and above all, show that a comprehensive problem analysis for a specific target behavior is a necessary step to induce behavioral change.

Abstract
OBJECTIVE To assess implementation fidelity of the Stay One Step Ahead (SOSA), a complex intervention which was delivered by health visiting teams, children's centres, and family mentors and was aimed at preventing unintentional home injuries in children under 5 in disadvantaged communities. STUDY DESIGN A mixed-methods evaluation of the implementation fidelity of the SOSA intervention. METHODS A conceptual framework for implementation fidelity was used to triangulate data from questionnaires and semistructured interviews with parents and practitioners, observations of parent and practitioner contacts, and meeting documents. Quantitative data were analysed using logistic regression and descriptive statistics. Thematic analysis was used for qualitative data. RESULTS Parents in intervention wards were more likely to receive home safety advice from a practitioner than those living in matched control wards. Monthly safety messages and family mentor home safety activities were delivered with greater fidelity than other intervention components. Content most frequently adapted included the home safety checklist used by health visiting teams, and safety weeks delivered at children's centres. CONCLUSION Consistent with similarly complex interventions, SOSA was delivered with variable fidelity in a challenging environment. The findings add to the body of evidence on implementation fidelity of home injury prevention programmes, providing important information for future intervention development and delivery.

Implications of a complexity perspective for systematic reviews and guideline development in health decision making. BMJ Glob Health 2019; 4:e000899.

Abstract
There is growing interest in the potential for complex systems perspectives in evaluation. This reflects a move away from interest in linear chains of cause-and-effect, towards considering health as an outcome of interlinked elements within a connected whole. Although systems-based approaches have a long history, their concrete implications for health decisions are still being assessed. Similarly, the implications of systems perspectives for the conduct of systematic reviews require further consideration. Such reviews underpin decisions about the implementation of effective interventions, and are a crucial part of the development of guidelines. Although they are tried and tested as a means of synthesising evidence on the effectiveness of interventions, their applicability to the synthesis of evidence about complex interventions and complex systems requires further investigation. This paper, one of a series of papers commissioned by the WHO, sets out the concrete methodological implications of a complexity perspective for the conduct of systematic reviews. It focuses on how review questions can be framed within a complexity perspective, and on the implications for the evidence that is reviewed. It proposes criteria which can be used to determine whether or not a complexity perspective will add value to a review or an evidence-based guideline, and describes how to operationalise key aspects of complexity as concrete research questions. Finally, it shows how these questions map onto specific types of evidence, with a focus on the role of qualitative and quantitative evidence, and other types of information.

Abstract
Behavioral medicine provides insight in to the problem of injury prevention. Society often views unintentional injuries as only an accident when in reality many accident-related injuries are preventable. However, barriers to behavioral change in injury prevention exist for both patients (eg, inconvenience, perceived risk-benefit ratio) and health care providers (eg, feeling of badgering nonadherent patients, patient misinformation). To overcome barriers, the article discusses strategies for health care providers to address injury prevention such as choosing active over passive strategies, informing patients of predictable injury-prone circumstances, and individualizing patient risks.

Abstract
The recent move of public health back to English local government has reignited debates about the role of a medicalised public health profession. The explicit policy rationale for the move was that local government is the arena in which the social determinants of health can be addressed, and that public health specialists could provide neutral evidence to support action on these. However, if a discourse of 'evidence-based' policy is in principle (if not practice) relatively unproblematic within the health arena, within the more overtly politicised local government space, rather different policy imperatives come to the fore. Responding to calls for research on evidence in practice, this article draws on ethnographic data of local authorities in the first year of the reorganised public health function. Focusing on alcohol policy, we explore how decisions that affect public health are rationalised and enacted through discourses of localism, empiricism and holism. These frame policy outcomes as inevitably plural and contingent: a framing which sits uneasily with normative discourses of evidence-based policy. We argue that locating public health in local government necessitates a refocusing of how evidence for public health is conceptualised, to incorporate multiple, and political, understandings of health and wellbeing.

Implementing an Injury Prevention Briefing to aid delivery of key fire safety messages in UK children's centres: qualitative study nested within a multi-centre randomised controlled trial. BMC Public Health 2014; 14:1256. [PMID: 25492496 PMCID: PMC4295482 DOI: 10.1186/1471-2458-14-1256] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2014] [Accepted: 11/19/2014] [Indexed: 11/24/2022] Open
Abstract
Background To improve the translation of public health evidence into practice, there is a need to increase practitioner involvement in initiative development, to place greater emphasis on contextual knowledge, and to address intervention processes and outcomes. Evidence that demonstrates the need to reduce childhood fire-related injuries is compelling but its translation into practice is inconsistent and limited. With this knowledge the Keeping Children Safe programme developed an "Injury Prevention Briefing (IPB)" using a 7 step process to combine scientific evidence with practitioner contextual knowledge. The IPB was designed specifically for children’s centres (CCs) to support delivery of key fire safety messages to parents. This paper reports the findings of a nested qualitative study within a clustered randomised controlled trial of the IPB, in which staff described their experiences of IPB implementation to aid understanding of why or how the intervention worked. Methods Interviews were conducted with key staff at 24 CCs participating in the two intervention arms: 1) IPB supplemented by initial training and regular facilitation; 2) IPB sent by post with no facilitation. Framework Analysis was applied to these interview data to explore intervention adherence including; exposure or dose; quality of delivery; participant responsiveness; programme differentiation; and staff experience of IPB implementation. This included barriers, facilitators and suggested improvements. Results 83% of CCs regarded the IPB as a simple, accessible tool which raised awareness, and stimulated discussion and behaviour change. 15 CCs suggested minor modifications to format and content. Four levels of implementation were identified according to content, frequency, duration and coverage. Most CCs (75%) achieved ‘extended’ or ‘essential’ IPB implementation. Three universal factors affected all CCs: organisational change and resourcing; working with hard to engage groups; additional demands of participating in a research study. Six specific factors were associated with the implementation level achieved: staff engagement and training; staff continuity; adaptability and flexibility; other agency support; conflicting priorities; facilitation. CCs achieving high implementation levels increased from 58% (no facilitation) to 92% with facilitation. Conclusion Incorporating service provider perspectives and scientific evidence into health education initiatives enhances potential for successful implementation, particularly when supplemented by ongoing training and facilitation.

Abstract
BACKGROUND As part of a study considering the impact of a child weight management programme when rolled out at scale following an RCT, this qualitative study focused on acceptability and implementation for providers and for families taking part. METHODS Participants were selected on the basis of a maximum variation sample providing a range of experiences and social contexts. Qualitative interviews were conducted with 29 professionals who commissioned or delivered the programme, and 64 individuals from 23 families in 3 English regions. Topic guides were used as a tool rather than a rule, enabling participants to construct a narrative about their experiences. Transcripts were analysed using framework analysis. RESULTS Practical problems such as transport, work schedules and competing demands on family time were common barriers to participation. Delivery partners often put considerable efforts into recruiting, retaining and motivating families, which increased uptake but also increased cost. Parents and providers valued skilled delivery staff. Some providers made adaptations to meet local social and cultural needs. Both providers and parents expressed concerns about long term outcomes, and how this was compromised by an obesogenic environment. Concerns about funding together with barriers to uptake and engagement could translate into barriers to commissioning. Where these barriers were not experienced, commissioners were enthusiastic about continuing the programme. CONCLUSIONS Most families felt that they had gained something from the programme, but few felt that it had 'worked' for them. The demands on families including time and emotional work were experienced as difficult. For commissioners, an RCT with positive results was an important driver, but family barriers, alongside concerns about recruitment and retention, a desire for local adaptability with qualified motivated staff, and funding changes discouraged some from planning to use the intervention in future.

Abstract
While largely preventable, fire and hot water-related injuries are common in the United States. Measures recommended to reduce these injuries are smoke alarms (SAs) and lowered hot water temperatures. This study aims to: (i) describe the prevalence of working SAs and safe water temperatures among low-income, urban communities and (ii) explore the relationship between these behaviors and individuals' knowledge and beliefs about them. In this cross-sectional study, the Health Belief Model was used as a guide for understanding the safety behaviors. A total of 603 households had their SAs and hot tap water temperatures tested and were surveyed about their knowledge and beliefs related to these safety behaviors. We found that 40% of households had working SAs on every level and 57% had safe hot water temperatures. Perceived severity and self-efficacy were significantly associated with SA coverage, whereas perceived susceptibility and beliefs about benefits were significantly associated with safe hot water temperatures. This study demonstrates the need to increase the number of homes with working SAs and safe hot water temperatures. Messages focused on a safe home environment could communicate the ease and harm reduction features of SAs and benefits and risk reduction features of safe hot water temperatures.

Abstract
BACKGROUND Deaths and injuries related to fires are largely preventable events. In the UK, a plethora of community-based fire safety initiatives have been introduced over the last 25 years, often led by fire and rescue services, to address this issue. This paper focuses on one such initiative--home safety assessments (HSAs). Cheshire Fire and Rescue Service (in England) implemented a uniquely large-scale HSA intervention. This paper assesses its effectiveness. METHODS The impact of HSAs was assessed in relation to three outcomes: accidental dwelling fires (ADFs), ADFs contained and injuries arising from ADFs. A two-period comparison in fire-related rates of incidences in Cheshire between 2002 and 2011 was implemented, using Poisson regression and adjusting for the national temporal trend using a control group comprising the 37 other English non-metropolitan fire-services. RESULTS Significant reductions were observed in rates of ADFs [incidence rate ratios (IRR): 0.79, 95% confidence interval (CI): 0.74-0.83, P < 0.001, 2002/03-2007/08 versus 2008/09-2010/11] and associated injuries (IRR: 0.49, 95% CI: 0.39-0.60, P < 0.001, 2002/03-2006/07 versus 2007/08-2010/11), but not in the proportion of fires contained to room of origin. CONCLUSIONS There is strong evidence to suggest that the intervention was successful in reducing domestic fires and related injuries.

Abstract
Smoke alarms are one of the most promoted prevention strategies to reduce residential fire deaths, and they can reduce residential fire deaths by half. Smoke alarm function can be measured by two tests: the smoke alarm button test and the chemical smoke test. Using results from a randomized trial of smoke alarms, we compared smoke alarm response to the button test and the smoke test. The smoke alarms found in the study homes at baseline were tested, as well as study alarms placed into homes as part of the randomized trial. Study alarms were tested at 12 and 42 months postinstallation. The proportion of alarms that passed the button test but not the smoke test ranged from 0.5 to 5.8% of alarms; this result was found most frequently among ionization alarms with zinc or alkaline batteries. These alarms would indicate to the owner (through the button test) that the smoke alarm was working, but the alarm would not actually respond in the case of a fire (as demonstrated by failing the smoke test). The proportion of alarms that passed the smoke test but not the button test ranged from 1.0 to 3.0%. These alarms would appear nonfunctional to the owner (because the button test failed), even though the alarm would operate in response to a fire (as demonstrated by passing the smoke test). The general public is not aware of the potential for inaccuracy in smoke alarm tests, and burn professionals can advocate for enhanced testing methods. The optimal test to determine smoke alarm function is the chemical smoke test.

Abstract
OBJECTIVE To identify the predictors of residential fire deaths in the Ontario pediatric population using systematically collected data from the Office of the Chief Coroner. DESIGN Retrospective cohort study. SETTING Ontario. PARTICIPANTS Children younger than 16 years of age who died in accidental residential fires in Ontario between January 1, 2001, and December 31, 2006. MAIN OUTCOME MEASURES The study retrospectively reviewed the coroner's case files for 60 subjects who qualified according to the selection criteria. Reviewed documents included the coroner's investigation statements, autopsy reports, toxicology reports, fire marshal's reports, police reports, and Children's Aid Society (CAS) reports. Information on a range of demographic, behavioural, social, and environmental factors was collected. Statistical tests, including relative risk, relative risk confidence intervals, and χ(2) tests were performed to determine the correlation between factors of interest and to establish their significance. RESULTS Thirty-nine fire events resulting in 60 deaths occurred between 2001 and 2006. Fire play and electrical failures were the top 2 causes of residential fires. More fires occurred during the night (midnight to 9 AM) than during the day (9 AM to midnight). Nighttime fires were most commonly due to electrical failures or unattended candles, whereas daytime fires were primarily caused by unsupervised fire play and stove fires. Smoke alarms were present at 32 of 39 fire events (82%), but overall alarm functionality was only 54%. Children from families with a history of CAS involvement were approximately 32 times more likely to die in fires. CONCLUSION Risk factors for pediatric fire death in Ontario include smoke alarm functionality, fire play, fire escape behaviour, and CAS involvement. Efforts to prevent residential fire deaths should target these populations and risk factors, and primary care physicians should consider education around these issues as a primary preventive strategy for families with young children.

Abstract
BACKGROUND Injury in the home is common, accounting for approximately a third of all injuries. The majority of injuries to children under five and people aged 75 and older occur at home. Multifactorial injury prevention interventions have been shown to reduce injuries in the home. However, few studies have focused specifically on the impact of physical adaptations to the home environment and the effectiveness of such interventions needs to be ascertained. OBJECTIVES To determine the effect of modifications to the home environment on the reduction of injuries due to environmental hazards. SEARCH STRATEGY We searched The Cochrane Library, MEDLINE, EMBASE and other specialised databases. We also scanned conference proceedings and reference lists. We contacted the first author of all included randomised controlled trials. The searches were last updated to the end of December 2009, and were not restricted by language or publication status. SELECTION CRITERIA Randomised controlled trials. DATA COLLECTION AND ANALYSIS Two authors screened all abstracts for relevance, outcome and design. Two authors independently assessed methodological quality and extracted data from each eligible study. We performed meta-analysis to combine effect measures, using a random-effects model. We assessed heterogeneity using an I(2) statistic and a Chi(2) test. MAIN RESULTS We found 28 published studies and one unpublished study. Only two studies were sufficiently similar to allow pooling of data for statistical analyses. Studies were divided into three groups; children, older people and the general population/mixed age group. None of the studies focusing on children or older people demonstrated a reduction in injuries that were a direct result of environmental modification in the home. One study in older people demonstrated a reduction in falls and one a reduction in falls and injurious falls that may have been due to hazard reduction. One meta-analysis was performed which examined the effects on falls of multifactorial interventions consisting of home hazard assessment and modification, medication review, health and bone assessment and exercise (RR 1.09, 95% CI 0.97 to 1.23). AUTHORS' CONCLUSIONS There is insufficient evidence to determine whether interventions focused on modifying environmental home hazards reduce injuries. Further interventions to reduce hazards in the home should be evaluated by adequately designed randomised controlled trials measuring injury outcomes. Recruitment of large study samples to measure effect must be a major consideration for future trials. Researchers should also consider using factorial designs to allow the evaluation of individual components of multifactorial interventions.

Abstract
Background This review considers barriers to, and facilitators of, success for interventions to reduce unintentional injury to children in the home through supply and/or installation of home safety equipment, and looks at risk assessments. Methods A systematic review of qualitative research. Bibliographic databases were searched for studies on interventions to reduce unintentional child injury in the home, or on related attitudes and behaviours. Studies were quality appraised, findings extracted, and a conceptual framework was developed to assess factors affecting the success of interventions. Results Nine peer-reviewed journal articles were included. Barriers and facilitators were highlighted at organisational, environmental and personal levels. Effective provision of safety equipment involves ongoing support with installation and maintenance. Take up and success of interventions depends on adjusting interventions according to practical limitations and parents' cultural expectations. A particular barrier was parents' inability to modify rented or shared accommodation. Conclusions The review highlights ways in which health inequalities affect the take up and success of home safety interventions, and how health workers can use this knowledge to facilitate future interventions.

Abstract
BACKGROUND Child injury mortality and morbidity are a public health concern in European countries and data are scarce. Cross-national efforts are needed to identify high-risk groups, follow trends and assist in establishing European-wide safety legislation. This study investigates fatal child injuries in the home, as compared to those in transport in European countries. METHODS Injury mortality was extracted from the World Health Organization Mortality Database for the years 2002-04. The mortality rate per 100 000 population was calculated by age group for 16 contributing countries, grouped by their economic level of development. RESULTS Fatal home injuries were highest in children under 5 years of age and then sharply decreased, as opposed to road traffic injuries, which increased with age. The majority of the upper-middle-economy countries tended to have higher home injury incidence rates compared to the high-income countries. The top five injury causes all countries aggregated were drowning/submersion, thermal injuries, poisoning, falls and homicide, all of which account for almost 90% of home injury deaths. CONCLUSION Home injuries were the leading cause of injury death in children under 5 years of age in the countries under study and the inequalities found among the countries indicate potential for improvement. Evidence-based interventions exist to prevent these injuries and the barriers to their implementation ought to be determined and addressed.

Abstract
The focus on evidence-based practice is critical to addressing the issue of injuries, yet advances in the science of injury prevention have not always led to advances in practice. Effective approaches are not always adopted, or when adopted and transferred from one setting to another, they do not always achieve expected results. These challenges were the basis of two breakout sessions at the second European Injury Control and Safety Promotion Conference in Paris, France (October 2008). In summarising the key issues raised during those sessions, this article describes what is meant by evidence-based practice, discusses why evidence-based practice tends not to occur and considers approaches that may facilitate the adoption and implementation of evidence-based strategies. To address the challenge, specific action is required, both on the part of the research community and those responsible for developing and implementing injury prevention policies and programmes.

Abstract
Assistive technologies are critical to elders maintaining independence in the home. Adequate assessment of the patient's needs, the appropriateness of the device to that need, and the patient's motivation to use of a device is required for successful outcomes. A team approach is needed to ensure that devices are correctly prescribed, and the patient is taught how to use it effectively. A wide range of devices is available to support activities of daily living, mobility, home management, and safety. The use of personal computers is significantly expanding the possibility of independent living through support systems, monitoring systems, and information resources.

Abstract
Inequalities in childhood injury and safety practices exist, but there is little evidence that targeted interventions can reduce such inequalities. This study examines the effect of a home safety intervention on reducing inequalities in safety practices using a secondary analysis of data from a randomized controlled trial. Families with children <5 years from disadvantaged areas were randomized to receive a standardized health visitor safety consultation and free or low-cost safety equipment fitted in the home or to usual care. The impact of the intervention in terms of stair gate use and functioning smoke alarms was compared by ethnic group, maternal age, housing tenure, family type and receipt of state-provided means-tested benefits at 1-year follow-up. Marked inequalities were found for both safety practices by each socio-economic characteristic prior to the intervention. The intervention significantly reduced inequalities in stair gate use by housing tenure (P = 0.006) and receipt of benefits (P = 0.04), but did not reduce inequalities in functioning smoke alarms. We conclude that a home safety intervention targeted at deprived areas addressing the barriers of cost and needing help to fit equipment was only partially successful in reducing inequalities in safety practices. Other strategies will be required to reduce inequalities especially in relation to functioning smoke alarms.

Abstract
BACKGROUND Although the use of smoke alarms is widely recommended, little guidance is available on the types of alarms and batteries that function best. This study examined smoke alarm and battery function 12 months after installation in rural residential households. METHODS An RCT, involving the installation of either a photoelectric or ionizing smoke alarm with either a lithium or carbon-zinc battery, was conducted in 643 rural Iowa households in July 2003. The functionality of each installed smoke alarm was tested 12 months later. Generalized estimating equations were used to model the effects of alarm type and battery type on alarm function and false alarms 12 months after installation. RESULTS Of 643 study homes, 98.8% had at least one functioning alarm, and 81.5% had all alarms functioning 12 months after installation. No difference was observed in alarm function between photoelectric alarms and ionizing alarms 12 months after installation (OR=1.30, 95% CI=0.88, 1.92). However, photoelectric alarms had significantly lower odds of false alarms than ionizing alarms. Alarms with lithium batteries had 91% higher odds of functioning than those with carbon-zinc batteries. The main reasons for nonfunctioning included a missing battery (30.7%); a missing alarm (28%); and a disconnected battery (11.3%). CONCLUSIONS Although lithium batteries and photoelectric alarms are more expensive than their counterparts, the financial investment might be worthwhile in terms of overall performance.

Abstract
OBJECTIVES To bring together scientific evidence of what works in injury prevention with the knowledge and experience of practitioners, using a case study of smoke alarm installation from England. DESIGN There is good evidence of strategies to reduce injuries but less is known about the art of translating those strategies to implementation in real-world settings. England's Health Development Agency developed a structured process applicable to many public health fields, which integrates practitioner knowledge into the evidence base and reflects local contexts. The multistep process includes convening structured field meetings with local practitioners and policy makers, which focus on a mapping exercise of strategies, policies, targets, and funding streams related to childhood injury prevention, and barriers and facilitators relating to implementation of specific interventions. SETTING Meetings were held in six venues across England with 98 participants from a range of professional backgrounds and sectors. RESULTS The collective knowledge of participants provided many local insights unlikely to emerge in conventional research. Discussion topics covered key partners and sectors to include when planning a program; national policies and programs that could be used to drive the agenda; potential sources of funding; the importance of providing and installing appropriate smoke alarms; targeting of programs; and suggestions for gaining access to hard-to-reach populations. CONCLUSION This methodology represents an efficient way of gaining insight necessary for successful implementation of evidence based programs. It may be particularly useful in lower and middle income countries, serving to translate evidence into the local contexts and circumstances within which practitioners operate.

Abstract
BACKGROUND Injury in the home is extremely common, accounting for around a third of all injuries. The majority of injuries of children under five and people aged 75 and over, occur at home. Multifactorial injury prevention interventions have been shown to reduce injuries in the home. However, few studies have focused specifically on the impact of physical adaptations to the home environment and the effectiveness of such interventions needs to be ascertained. OBJECTIVES To review the evidence for the effect on injuries of modification of the home environment with a primary focus on interventions to reduce physical hazards. SEARCH STRATEGY We searched The Cochrane Library, MEDLINE, EMBASE, National Research Register and other specialised databases. We also scanned conference proceedings and reference lists. In addition, we contacted experts and trialists in the field. The searches were not restricted by language or publication status. The searches were last updated in December 2004. SELECTION CRITERIA Randomised controlled trials. DATA COLLECTION AND ANALYSIS All abstracts were screened by two authors for relevance, outcome and design. Two authors independently assessed methodological quality and extracted data from each eligible study. MAIN RESULTS We found 18 published and one unpublished trials. Trials were not sufficiently similar to allow pooling of data by statistical analyses, so this review takes a narrative form. Studies were divided into three groups based on the primary population sample; children (five studies), older people (14 studies) and the general population/mixed age group (no studies). None of the studies focusing on children demonstrated a reduction in injuries that might have been due to environmental adaptation in the home; one study reported a reduction in injuries and in hazards but the two could not be linked. Of the 14 included studies in older people, none demonstrated a reduction in injuries due to hazard reduction, although two demonstrated a reduction in falls that could be due to hazard reduction. AUTHORS' CONCLUSIONS There is insufficient evidence to determine the effects of interventions to modify environmental home hazards. Further interventions to reduce hazards in the home should be evaluated by adequately designed randomised controlled trials measuring injury outcomes. Recruitment of large study samples to measure effect must be a major consideration for future trials.

Abstract
BACKGROUND Fire-related mortality rates are known to be higher in Aboriginal people in BC. The purpose of this study was to describe the epidemiology and context of fire-related deaths in this population. METHODS All death registrations attributable to fires in the province were identified by the B.C. Vital Statistics Agency (1991-2001). Age-specific death rates (ASDR) and age-standardized mortality rates (ASMR) were calculated for Status Indians and other residents. Data from Coroner's reports from the B.C. Coroners' Service (1997-2001) were used to describe the context of Aboriginal fire-related deaths. RESULTS The overall fire-related ASMR for Status Indians and other residents were 0.66 deaths and 0.07 deaths/10,000 population respectively. Annual ASMR for both populations were constant over the study period. ASDR were higher in every age category for Status Indians; children and seniors had higher rates in both populations. Twenty-seven Aboriginal fatalities (20 fires) were identified for the contextual analysis. Key findings were: 48% of the total sample had elevated blood alcohol levels; 30% of the fires were caused by lit cigarettes (majority of decedents were intoxicated); 15% of the fires were caused by electric heating sources; at least 34% of fires occurred in homes with absent or non-functional smoke alarms. INTERPRETATION Fire-related mortality among Aboriginal people in BC is a preventable public health concern. In this population, fire safety and prevention programs should consider improving the prevalence of functioning smoke alarms, promoting the safe use of heat sources, and decreasing smoking behaviours and the use of alcohol.

Abstract
BACKGROUND In this methodological paper we document the interpretation of a mixed methods study and outline an approach to dealing with apparent discrepancies between qualitative and quantitative research data in a pilot study evaluating whether welfare rights advice has an impact on health and social outcomes among a population aged 60 and over. METHODS Quantitative and qualitative data were collected contemporaneously. Quantitative data were collected from 126 men and women aged over 60 within a randomised controlled trial. Participants received a full welfare benefits assessment which successfully identified additional financial and non-financial resources for 60% of them. A range of demographic, health and social outcome measures were assessed at baseline, 6, 12 and 24 month follow up. Qualitative data were collected from a sub-sample of 25 participants purposively selected to take part in individual interviews to examine the perceived impact of welfare rights advice. RESULTS Separate analysis of the quantitative and qualitative data revealed discrepant findings. The quantitative data showed little evidence of significant differences of a size that would be of practical or clinical interest, suggesting that the intervention had no impact on these outcome measures. The qualitative data suggested wide-ranging impacts, indicating that the intervention had a positive effect. Six ways of further exploring these data were considered: (i) treating the methods as fundamentally different; (ii) exploring the methodological rigour of each component; (iii) exploring dataset comparability; (iv) collecting further data and making further comparisons; (v) exploring the process of the intervention; and (vi) exploring whether the outcomes of the two components match. CONCLUSION The study demonstrates how using mixed methods can lead to different and sometimes conflicting accounts and, using this six step approach, how such discrepancies can be harnessed to interrogate each dataset more fully. Not only does this enhance the robustness of the study, it may lead to different conclusions from those that would have been drawn through relying on one method alone and demonstrates the value of collecting both types of data within a single study. More widespread use of mixed methods in trials of complex interventions is likely to enhance the overall quality of the evidence base.

Abstract
INTRODUCTION While smoke alarm installation programs can help prevent residential fire injuries, the costs of running these programs are not well understood. METHOD We conducted a retrospective cost analysis of a smoke alarm installation program in 12 funded communities across four states. Costs included financial and economic resources needed for training, canvassing, installing, and following-up, within four cost categories: (a) personnel, (b) transportation, (c) facility, and (d) supplies. RESULTS Local cost per completed home visit averaged 214.54 dollars, with an average local cost per alarm installed of 115.02 dollars. Combined state and local cost per alarm installed across all four states averaged 132.15 dollars. For every 1% increase in alarm installation, costs per alarm decrease by 1.32 dollars. CONCLUSIONS As more smoke alarms are installed, the average installation cost per alarm decreases. By demonstrating effective economies of scale, this study suggests that smoke alarm programs can be implemented efficiently and receive positive economic returns on investment.

Abstract
OBJECTIVE To explore data on factors affecting implementation processes in papers contributing to a Cochrane systematic review (SR) of smoke alarm interventions, supplemented by further papers not included in the review. DESIGN Screening for data on implementation on the basis of: (1) primary studies included in a Cochrane SR, (2) further papers relating to these and similar studies, and (3) approaches to authors of these and other relevant studies and reports. RESULTS Relatively few data were found to help people seeking to implement smoke alarm promotion interventions. CONCLUSIONS For practitioners and policymakers to be able to build on research evidence, researchers and journal editors need to ensure that sufficient data are published, or are otherwise available to interested parties to move from understanding the evidence to using it.

Abstract
Insignificant or modest findings in intervention trials may be attributable to poorly designed or theorised interventions, poorly implemented interventions, or inadequate evaluation methods. The pre-existing context may also account for the effects observed. A combination of qualitative and quantitative methods is outlined that will permit the determination of how context level factors might modify intervention effectiveness, within a cluster randomised community intervention trial to promote the health of mothers with new babies. The methods include written and oral narratives, key informant interviews, impact logs, and inter-organisational network analyses. Context level factors, which may affect intervention uptake, success, and sustainability are the density of inter-organisational ties within communities at the start of the intervention, the centrality of the primary care agencies expected to take a lead with the intervention, the extent of context-level adaptation of the intervention, and the amount of local resources contributed by the participating agencies. Investigation of how intervention effects are modified by context is a new methodological frontier in community intervention trial research.
