we must continue to grow our knowledge base on the nature and circumstances of RRA to prevent harm to an increasing vulnerable population of nursing home residents and ensure a safe working environment for staff.

This is the first national study in Australia, and the largest internationally, to examine RRA deaths using medicolegal data. This generates hypotheses for future research on the effect of environmental and organizational factors on the frequency and preventability of RRA.

There is a paucity of research describing completed suicide among nursing home residents. More large-scale research is required using standardized methods for reporting information to better understand and prevent completed suicides in this setting.

BackgroundMedico-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).MethodsPubMed, 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.ResultsOf 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.ConclusionsTo 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.Electronic supplementary materialThe online version of this article (doi:10.1186/s12961-016-0096-1) contains supplementary material, which is available to authorized users.

This research provides a foundational understanding of suicide among nursing home residents in Australia and contributes important new information to the international knowledge base.

This study examined the frequency, nature and proximity of service contacts among victims and perpetrators of intimate partner homicide in Victoria, Australia. A retrospective review was conducted of coroner's records of 120 intimate partner homicides for the period 2000-2008. In 91 (75.8 %) of the cases, one or both parties had contact with a service in the 12 months preceding the homicide. The justice system was the most frequent point of contact among both parties, and the healthcare system was often the first and preferred point of contact for victims and perpetrators when seeking assistance individually. Overall, perpetrators were more likely to have contact with a service than victims, and the majority of all service contacts occurred within 1 month of the homicide. This paper outlines the prevention opportunities that exist within the service system and highlights the importance of interventions and treatments directed at perpetrators of family violence.

A significant proportion of nursing home resident deaths are from external causes and are potentially preventable. A shift in community attitudes is required toward an understanding that premature death of a resident from injury is not a natural part of life.
