Developing the history of unintentional injury: the use of coroners' records in early modern England

Drowning deaths between 1861 and 2000 in Victoria, Australia

OBJECTIVE

To identify the long-term patterns of drowning mortality in the state of Victoria, Australia, and to describe the historical context in which the decrease occurred.

METHODS

We obtained data on drowning deaths and population statistics from the Australian Bureau of Statistics and its predecessors for the period 1861 to 2000. From these data, we calculated drowning death rates per 100 000 population per year, by gender and age. We reviewed primary and secondary historical resources, such as government and newspaper archives, books and the Internet, to identify changes or events in the state that may have affected drowning mortality.

FINDINGS

From 1861 to 2000, at least 18 070 people drowned in Victoria. Male drowning rates were higher than those for females in all years and for all ages. Both sexes experienced the highest drowning rate in 1863 (79.5 male deaths per 100 000 population and 18.8 female death per 100 000 population). The lowest drowning rate was documented in 2000 (1.4 male deaths per 100 000 population and 0.3 female deaths per 100 000 population). The reduction patterns of drowning mortality occurred within a historical context of factors that directly affected drowning mortality, such as the improvement in people's water safety skills, or those that incidentally affected drowning mortality, like infrastructure development.

CONCLUSION

We identified patterns of reduction in drowning mortality, both in males and females and across age groups. These patterns could be linked to events and factors that happened in Victoria during this period. These findings may have relevance to current developing communities.

The utility of medico-legal databases for public health research: a systematic review of peer-reviewed publications using the National Coronial Information System

BACKGROUND

Medico-legal death investigations are a recognised data source for public health endeavours and its accessibility has increased following the development of electronic data systems. Despite time and cost savings, the strengths and limitations of this method and impact on research findings remain untested. This study examines this issue using the National Coronial Information System (NCIS).

METHODS

PubMed, ProQuest and Informit were searched to identify publications where the NCIS was used as a data source for research published during the period 2000-2014. A descriptive analysis was performed to describe the frequency and characteristics of the publications identified. A content analysis was performed to identify the nature and impact of strengths and limitations of the NCIS as reported by researchers.

RESULTS

Of the 106 publications included, 30 reported strengths and limitations, 37 reported limitations only, seven reported strengths only and 32 reported neither. The impact of the reported strengths of the NCIS was described in 14 publications, whilst 46 publications discussed the impacts of limitations. The NCIS was reported to be a reliable source of quality, detailed information with comprehensive coverage of deaths of interest, making it a powerful injury surveillance tool. Despite these strengths, researchers reported that open cases and missing information created the potential for selection and reporting biases and may preclude the identification and control of confounders.

CONCLUSIONS

To ensure research results are valid and inform health policy, it is essential to consider and seek to overcome the limitations of data sources that may have an impact on results.

Manner Determination in Forensic Pathology

A traditional function of forensic pathologists in the United States is the determination of cause and manner of death. The formal certification of manner of death is an American innovation of the early 20th century. Many countries do not follow this tradition. While originally established for vital statistics and public health purposes, the use of manner has grown to include increased legal, social, and business functions. The expanded role of manner determination has led to controversy regarding its true function, who should do it, and if it should be done at all. Much of the controversy regarding manner determination is due to inherent ambiguities that arise primarily from the limited number of categories and fundamental epistemic issues. Much of the heterogeneity in manner determination is structural and not a matter of error. Other criticisms come from those who focus on the legal implications of manner determination. Some have claimed that the use of circumstantial information in manner determination constitutes cognitive bias. Others suggest that manner determination is not a medical issue at all. A response is that the integration of circumstances and history with physical examination and laboratory findings represents the classic paradigm of medical diagnosis, and reinforces rather than opposes recognition that this is the practice of medicine. Transferring the task of manner determination to another agency would do nothing to improve accuracy, timeliness, or function. Other candidates to perform this function would be successful only to the degree that they were trained and function as forensic pathologists.
