The incidence of injuries caused by electric bicycles (E-bikes) and powered scooters (P-scooters) continues to increase. Data on the severity of those injuries is conflicting. The purpose of this study was to explore secular trends in the incidence and severity characteristics of patients following E-bike and P-scooter injuries and predictors for major trauma. ⋯ The incidence of E-bike and P-scooter injuries sharply increased over time, with a parallel elevation in numbers of hospitalizations, surgical interventions, and major trauma cases. Major trauma percentages did not increase during the study period. Male sex and E-bikes emerged as independent predictors for major trauma.

Traumatic rib fracture is associated with a high morbidity rate and identifying patients at risk of developing pulmonary complications (PC) can guide management and potentially decrease unnecessary intensive care admissions. Therefore, we sought to assess and compare the utility of a physiologic parameter, vital capacity (VC), with the admission radiologic findings (RibScore) in predicting PC in patients with rib fractures. ⋯ VC and RibScore emerged as independent predictors of PC. However, VC was not found to be superior to RibScore in predicting PC. Further prospective research is warranted to validate the findings of this study.

Observational Study
The relationship between patient volume and mortality in NSW major trauma service hospitals.
Conventional wisdom is that Major Trauma Services (MTS) treating larger volumes of severe trauma patients will have better outcomes than lower volume centres, but recent studies from Europe have questioned this relationship. We aimed to determine if there is a relationship between patient volume and outcome in New South Wales (NSW) MTS hospitals. ⋯ There was no mortality difference between high and low volume MTS demonstrated. Length of hospital stay significantly increased with increasing volume however.

Various attempts at automation have been made to reduce the administrative burden of manually assigning Abbreviated Injury Severity (AIS) codes to derive Injury Severity Scores (ISS) in trauma registry data. The accuracy of the resulting measures remains unclear, especially in the New Zealand (NZ) context. The aim of this study was to compare ISS derived from hospital discharge International Classification of Diseases Australian Modification (ICD-10-AM) codes with ISS recorded in the NZ Trauma Registry (NZTR). ⋯ Although the overall agreement between NZTR-ISS and ICD-ISS was slight, ICD-derived scores may be useful to describe injury patterns and for body region-specific estimations when manually coded ISS are not available.
