Review Comparative Study
Comparing responsible and non-responsible drivers to assess determinants of road traffic collisions: time to standardise and revisit.
In 1994, Robertson and Drummer formalised the responsibility analysis as an alternative to case-control studies in the study of road traffic crashes. Our objective was to assess whether published responsibility studies respected standards defining adequate case-control studies. ⋯ Basic requirements of case-control studies are often not or not clearly met in responsibility studies. There is a need to revisit the method and to adapt existing publication standards to the way responsibility studies are reported.

Observational Study
Effectiveness of the 2005 compulsory personal flotation device (PFD) wearing regulations in reducing drowning deaths among recreational boaters in Victoria, Australia.
To investigate whether the Victorian mandatory personal flotation device wearing regulations that came into effect on 1 December 2005 reduced drowning deaths among recreational boaters in Victoria, Australia. ⋯ These findings provide further support for the adoption of a regulatory approach to personal flotation device wearing to reduce drowning among recreational boaters.

Determining the relationship between gun ownership levels and firearm homicide rates is critical to inform public health policy. Previous research has shown that state-level gun ownership, as measured by a widely used proxy, is positively associated with firearm homicide rates. A newly developed proxy measure that incorporates the hunting license rate in addition to the proportion of firearm suicides correlates more highly with state-level gun ownership. ⋯ Using state-specific data for the years 1981-2010, we modelled these rates as a function of gun ownership level, controlling for potential confounding factors. We used a negative binomial regression model and accounted for clustering of observations among states. We found that state-level gun ownership as measured by the new proxy, is significantly associated with firearm and total homicides but not with non-firearm homicides.

To examine national trends in fall-related injuries among older adults treated in emergency departments (ED) and project these injuries until the year 2030. The Web-based Injury Statistics Query and Reporting System was used to generate data on fall-related injuries treated in ED. Joinpoint regression analysis was used to examine the average annual change in injury rates over time. ⋯ Assuming the increase in fall-related injury rates remains unchanged, the number of fall-related injuries may increase to 5.7 million by the year 2030. Fall-related injuries among older adults treated in ED increased in the USA during the study period. Moreover, a marked increase in the number of these injuries may occur over the next decades.
