Fire-related deaths in India in 2001: a retrospective analysis of data

Burden, characteristics, and outcome of injury among females: observations from Bengaluru, India

PURPOSE

With injuries becoming a leading cause of mortality, morbidity, disability, and socioeconomic losses in India and other low- and middle-income countries, its impact on the female population is significant, affecting their multiple roles and functions. The objectives of the present study were to identify the burden, causes, characteristics, and outcomes of injury among females in Bengaluru city.

METHODS

Information on fatal and nonfatal injuries was collected from the Bangalore city police and the emergency rooms of 22 partner hospitals, respectively, under the Bengaluru Injury Surveillance Program in 2007 and 2008. Data were collected in an uniform manner by trained personnel using standardized methods.

FINDINGS

Females across all age groups accounted for 26% of fatal and 23% of nonfatal injuries and the highest numbers were among those 16 to 45 years old. Burns and hanging were the leading causes of death; road crashes and poisonings were the major causes of nonfatal injuries. Nearly half of the fatal and one third of the nonfatal injuries were suicides. Pedestrians and two-wheeler riders/pillions were mainly involved in road crashes. Very few received first aid at the injury site and the commonest modes of transportation were a private vehicle or taxi and the local three-wheeler vehicle. More than half of the injured were admitted in the hospitals for medical or surgical management.

CONCLUSION

Injuries are a major, preventable public health problem. There is a need to strengthen injury prevention and control programs, as well as increased research to understand risk factors and injury mechanisms.

Case series of completed suicides by burning over a 13-year period

Suicide by burning is an extreme act that is uncommon in the United States and throughout the Western world. The characteristics of people who complete such acts are not well understood. To address this issue, we examined the death records of the King County Medical Examiner's Office in Washington State over the 13 years from 1996 to 2009. Twenty-five cases of suicide by burning were identified and used to characterize decedent demographics, circumstances of death, and motivating factors. Compared to other methods of suicide, burning demonstrated a significant overrepresentation of decedents who were women, 40-59 years of age, and Asian/Pacific Islander. They also tended to have previous psychiatric illness and/or substance abuse issues. Self-burning predominantly occurred at the decedent's residence with the intent of suicide given. There was no unifying theme in motivating factors. Together, these data represent the characteristics of people whose death is because of suicide by burning in King County, Washington.

The global burden of unintentional injuries and an agenda for progress

According to the World Health Organization, unintentional injuries were responsible for over 3.9 million deaths and over 138 million disability-adjusted life-years in 2004, with over 90% of those occurring in low- and middle-income countries (LMIC). This paper utilizes the year 2004 World Health Organization Global Burden of Disease Study estimates to illustrate the global and regional burden of unintentional injuries and injury rates, stratified by cause, region, age, and gender. The worldwide rate of unintentional injuries is 61 per 100,000 population per year. Overall, road traffic injuries make up the largest proportion of unintentional injury deaths (33%). When standardized per 100,000 population, the death rate is nearly double in LMIC versus high-income countries (65 vs. 35 per 100,000), and the rate of disability-adjusted life-years is more than triple in LMIC (2,398 vs. 774 per 100,000). This paper calls for more action around 5 core areas that need research investments and capacity development, particularly in LMIC: 1) improving injury data collection, 2) defining the epidemiology of unintentional injuries, 3) estimating the costs of injuries, 4) understanding public perceptions about injury causation, and 5) engaging with policy makers to improve injury prevention and control.

Verbal autopsy: methods in transition

Understanding of global health and changing morbidity and mortality is limited by inadequate measurement of population health. With fewer than one-third of deaths worldwide being assigned a cause, this long-standing dearth of information, almost exclusively in the world's poorest countries, hinders understanding of population health and limits opportunities for planning, monitoring, and evaluating interventions. In the absence of routine death registration, verbal autopsy (VA) methods are used to derive probable causes of death. Much effort has been put into refining the approach for specific purposes; however, there has been a lack of harmony regarding such efforts. Subsequently, a variety of methods and principles have been developed, often focusing on a single aspect of VA, and the resulting literature provides an inconsistent picture. By reviewing methodological and conceptual issues in VA, it is evident that VA cannot be reduced to a single one-size-fits-all tool. VA must be contextualized; given the lack of "gold standards," methodological developments should not be considered in terms of absolute validity but rather in terms of consistency, comparability, and adequacy for the intended purpose. There is an urgent need for clarified thinking about the overall objectives of population-level cause-of-death measurement and harmonized efforts in empirical methodological research.

Prophylactic antibiotics for burns patients: systematic review and meta-analysis

OBJECTIVE

To assess the evidence for prophylactic treatment with systemic antibiotics in burns patients.

DESIGN

Systematic review and meta-analysis of randomised or quasi-randomised controlled trials recruiting burns inpatients that compared antibiotic prophylaxis (systemic, non-absorbable, or topical) with placebo or no treatment.

DATA SOURCES

PubMed, Cochrane Library, LILACS, Embase, conference proceedings, and bibliographies. No language, date, or publication status restrictions were imposed. Review methods Two reviewers independently extracted data. The primary outcome was all cause mortality. Risk or rate ratios with 95% confidence intervals were pooled with a fixed effect model if no heterogeneity was present.

RESULTS

17 trials were included. Trials that assessed systemic antibiotic prophylaxis given for 4-14 days after admission showed a significant reduction in all cause mortality (risk ratio 0.54, 95% confidence interval 0.34 to 0.87, five trials). The corresponding number needed to treat was 8 (5 to 33), with a control event rate of 26%. Perioperative non-absorbable or topical antibiotics alone did not significantly affect mortality. There was a reduction in pneumonia with systemic prophylaxis and a reduction in wound infections with perioperative prophylaxis. Staphylococcus aureus infection or colonisation was reduced with anti-staphylococcal antibiotics. In three trials, resistance to the antibiotic used for prophylaxis significantly increased (rate ratio 2.84, 1.38 to 5.83). The overall methodological quality of the trials was poor.

CONCLUSIONS

Prophylaxis with systemic antibiotics has a beneficial effect in burns patients, but the methodological quality of the data is weak. As such prophylaxis is currently not recommended for patients with severe burns other than perioperatively, there is a need for randomised controlled trials to assess its use.

Epidemiology of burn injuries: highlighting cultural and socio-demographic aspects

Burns are devastating injuries that disproportionately affect people in developing countries, including children. In addition to a high mortality rate, survivors are burdened with life-long physical and emotional scars. The etiology and nature of burn injuries varies significantly by country, and this chapter explores the predominant causes and patterns of burn injury in both the developing and industrialized worlds. Gender differences play a significant role in the risk of burn injuries, across a spectrum with a predominance of women injured in fires from cooking and heating fuels in the developing world and industrial accidents primarily affecting men in developed nations. Children are particularly vulnerable to burn injuries, accounting for almost 50% of all burn patients in some studies. A majority of pediatric burns are scald injuries usually affecting very young children below the age of 5 years, and we discuss the behavioral patterns underlying this finding. Finally, the elderly form a rapidly increasing proportion of the population in many countries, and are often burdened with comorbidities that are likely to pose significant challenges in burn care.

Epidemiology of burn injuries II: psychiatric and behavioural perspectives

Modern technological advances have decreased the incidence and severity of burn injuries, and medical care improvements of burn injuries have significantly increased survival rates, particularly in developed countries. Still, fire-related burn injuries are responsible for 300,000 deaths and 10 million disability-adjusted life years lost annually worldwide. The extent to which psychiatric and behavioural factors contribute to the incidence and outcomes of these tragedies has not been systematically documented, and the available data is often insufficient to reach definitive conclusions. Accordingly, this article reviews the evidence of psychiatric and behavioural risk factors and prevention opportunities for burn injuries worldwide. Psychiatric prevalence rates and risk factors for burn injuries, prevalence and risks associated with 'intentional' burn injuries (self-immolation, assault, and child maltreatment), and prevention activities targeting the general population and those with known psychiatric and behavioural risk factors are discussed. These issues are substantially interwoven with many co-occurring risk factors. While success in teasing apart the roles and contributions of these factors rests upon improving the methodology employed in future research, the nature of this entanglement increases the likelihood that successful interventions in one problem area will reap benefits in others.

Global and regional causes of death

BACKGROUND

Assessing the causes of death across all regions of the world requires a framework for integrating, and analysing, the fragmentary information that is available on numbers of deaths and their cause distributions. This paper provides an overview of the met and methods used by the World Health Organization to develop global-, regional- and country-level estimates of mortality for a comprehensive set of causes, and provides an overview of global and regional levels and patterns of causes of death for the year 2004. The paper also examines some of the data gaps, uncertainties and limitations in the resulting mortality estimates.

SOURCES OF DATA

Deaths for 136 disease and injury causes were estimated from available death registration data (111 countries), sample death registration data (India and China), and for the remaining countries from census and survey information, and cause-of-death models. Population-based epidemiological studies and notifications systems also contributed to estimating mortality for 21 of these causes (representing 28% of deaths globally, 58% in Africa).

AREAS OF AGREEMENT

Ischaemic heart disease and cerebrovascular disease are the leading causes of death, followed by lower respiratory infections, chronic obstructive pulmonary disease and diarrhoeal diseases. AIDS and TB are the sixth and seventh most common causes of death, respectively, lower than in previous estimates. One-half of all child deaths are from four preventable and treatable communicable diseases. Globally, around 6 in 10 deaths are from non-communicable diseases, 3 from communicable diseases and 1 from injuries. Injury mortality is highest in South-East Asia, Latin America and the Eastern Mediterranean region. These results illustrate continuing huge disparities in risks and causes of death across the world.

AREAS OF CONTROVERSY

Global mortality analyses of the type reported here have been criticized for making estimates of mortality for regions with limited, incomplete and uncertain data. Estimates presented here use a range of techniques depending on the type and quality of evidence. Better evidence on levels of adult mortality is needed for African countries.

GROWING POINTS

Considerable gaps and deficiencies remain in the information available on causes of death. Nine of 10 deaths in 2004 occurred in low- and middle-income countries, reinforcing the fundamental importance of improving mortality statistics as a measure of health status in the developing world. Acknowledging the controversies around use of incomplete and uncertain data, systematic assessments and synthesis of the available evidence will continue to provide important inputs for global health planning.

AREAS TIMELY FOR DEVELOPING RESEARCH

Innovative methods involving sample registration, and the use of verbal autopsy questionnaires in surveys, are needed to address these gaps. Research on strategies to improve comparability of cause-of-death certification and coding practices across countries is also a high priority.
