Fire-related deaths in Sweden : An analysis of data quality, causes and risk patterns (Engelska)
Abstract [sv]

Risken att omkomma genom brand har mer än halverats under de senaste 60 åren i Sverige. Det är idag mycket ovanligt att små barn omkommer i brand men samma positiva utveckling kan inte ses för de äldre. En åldrande befolkning som i ökande omfattning förväntas bo kvar hemma innebär att denna grupp måste prioriteras i framtida brandskyddsarbete. Sambearbetning av data från tre nationella register visar att rutinmässigt framtagen statistik systematiskt underskattar den verkliga situationen. Män, äldre, ensamboende och ekonomiskt svaga är särskilt riskutsatta grupper att omkomma vid bostadsbränder och förekomst av alkohol bland offren är mycket vanligt. Den i särklass vanligaste brandorsaken är rökning. Trots att varje dödsbrand är unik kan det omfattande materialet beskrivas av relativt få och tydligt avgränsade typer av händelser som var och en måste mötas med relevanta preventiva insatser. Avhandlingen visar att dödsbränder i bostäder i huvudsak är ett socialt problem och att det kommer att krävas uthålliga och breda strategier, bestående både av sociala och tekniska åtgärder för att skydda de mest riskutsatta och sårbara människorna i samhället.

Abstract [en]

In Sweden, more than 100 people die in fires every year and there is a societal goal of decreasing the risk of fire-related deaths. A goal-orientated prevention approach needs to be credibly underpinned with an understanding of the extent of the problem, its causes and risk factors, aspects that have largely been missing in Sweden. Therefore, the purpose of this thesis was to analyze fatal fires and fatalities in Sweden from an epidemiological perspective. The historical trends show that the risk of dying due to fire has decreased by more than 50% over the last 60 years in Sweden, with the largest decline being seen amongst children. In Sweden today, the risk of young children dying in a fire is very low. However, the risk of dying in fires has not declined to the same extent among elderly. In light of the aging Swedish population, older people must therefore be a priority in future fire protection. To investigate fire fatalities, data from three different national registers were combined. By combining the three sources, it was clear that the present routine statistics systematically underestimate the true situation. In-depth analysis regarding residential fires show that men and elderly are particularly at risk, as well as people living alone, as well as those on low income, social security benefits and health-related early-retirement benefits. The most common cause of fire was smoking and the presence of alcohol among the victims was very common. When combined, the extensive material can be simplified and described by well-defined clusters that each can be meet with relevant preventive efforts. Crucially, however, it is clear that mortality in residential fires is essentially a social problem and improving the protection of the most vulnerable people in society needs to be ascertained through sustained and holistic strategies, consisting of both social and technical measures. To establish and facilitate this, a cross-sectoral approach within municipalities and central government is needed.

Abstract [en]

Introduction: Fire-related fatalities and injuries have become a growing governmental concern in Sweden, and a national vision zero strategy has been adopted stating that nobody should get killed or seriously injured from fires. There is considerable uncertainty, however, regarding the numbers of both deaths and injuries due to fires. Different national sources present different numbers, even on deaths, which obstructs reliable surveillance of the problem over time. We assume the situation is similar in other countries. This study seeks to assess the true number of fire-related deaths in Sweden by combining sources, and to verify the coverage of each individual source. By doing so, we also wish to demonstrate the possibilities of improved surveillance practices. Method: Data from three national sources were collected and matched; a special database on fatal fires held by The Swedish Contingencies Agency (nationally responsible for fire prevention), a database on forensic medical examinations held by the National Board of Forensic Medicine, and the cause of death register held by the Swedish National Board of Health and Welfare. Results: The results disclose considerable underreporting in the single sources. The national database on fatal fires, serving as the principal source for policymaking on fireprevention matters, underestimates the true situation by 20 %. Its coverage of residential fires appears to be better than other fires. Conclusions: Systematic safety work and informed policy-making presuppose access to correct and reliable numbers. By combining several different sources, as suggested in this study, the national database on fatal fires is now considerably improved and includes regular matching with complementary sources.

Abstract [en]

Introduction

Residential fires represent the largest category of fatal fires in Sweden. The purpose of this study was to describe the epidemiology of fatal residential fires in Sweden and to identify clusters of events.

Method

Data was collected from a database that combines information on fatal fires with data from forensic examinations and the Swedish Cause of Death-register. Mortality rates were calculated for different strata using population statistics and rescue service turnout reports. Cluster analysis was performed using multiple correspondence analysis with agglomerative hierarchical clustering.

Results

Male sex, old age, smoking, and alcohol were identified as risk factors, and the most common primary injury diagnosis was exposure to toxic gases. Compared to non-fatal fires, fatal residential fires more often originated in the bedroom, were more often caused by smoking, and were more likely to occur at night. Six clusters were identified. The first two clusters were both smoking-related, but were separated into (1) fatalities that often involved elderly people, usually female, whose clothes were ignited (17% of the sample), (2) middle-aged (45–64 years old), (often) intoxicated men, where the fire usually originated in furniture (30%). Other clusters that were identified in the analysis were related to (3) fires caused by technical fault, started in electrical installations in single houses (13%), (4) cooking appliances left on (8%), (5) events with unknown cause, room and object of origin (25%), and (6) deliberately set fires (7%).

Conclusions

Fatal residential fires were unevenly distributed in the Swedish population. To further reduce the incidence of fire mortality, specialized prevention efforts that focus on the different needs of each cluster are required.

Practical applications

Cooperation between various societal functions, e.g. rescue services, elderly care, psychiatric clinics and other social services, with an application of both human and technological interventions, should reduce residential fire mortality in Sweden.

Abstract [en]

Objectives: This study aimed to investigate the association between sociodemographic factors and residential fire fatalities in Sweden. A majority of fatal fires occur in housing. An understanding of risk factors and risk groups is a must for well-Founded decisions regarding targeted prevention efforts. There is a lack of consideration of the interrelation between sociodemographic factors and fire fatalities and there is a lack of high quality large-Scale studies. Methods: In this matched case-Control study, residential fire fatalities (cases, n=850) (age above 19 years old) were identified in the national register on fatal fires. Four controls per case were randomly matched by gender and age. ORs were calculated to assess the association between different sociodemographic factors with residential fire fatalities using conditional logistic regression. Results: Having low income, receiving social allowance and receiving health-Related early retirement pension were associated with an increased risk of dying in residential fires. The results also show clearly that adults dying in residential fires to a significantly lower extent were living together with a partner, were in work, were highly educated and lived in urban areas. However, contrary to previous research, living in rented apartments appeared not to influence the risk of death. Conclusions: In this study, we show that fatalities due to residential fires in Sweden are associated with some but not all of previously published sociodemographic risk factors. The results provide valuable information that can improve the guiding and targeting of fire mortality prevention strategies in Sweden.
