Equestrian Sports Safety: An Update on Safety Equipment and Event Medical Coverage.

Equestrian sports are associated with high rates of major injury compared to collision and powered two-wheel sports. Advancements in rider and horse safety equipment and the implementation of comprehensive emergency action planning standards may help mitigate injuries, particularly in regard to the Olympic disciplines of dressage, show jumping, and three-day eventing covered in this review. Personal safety equipment to consider includes helmets, safety and air vests, and horse tack including safety stirrups, acoustic dampeners, and breakaway reins.

Temporal compliance trends in a cluster randomization with crossover trial of out-of-hospital cardiac arrest.

Background: Low compliance to randomized nondrug interventions can affect treatment estimates of clinical trials. Cluster-randomized crossover may be appropriate for increasing compliance in the out-of-hospital cardiac arrest setting.

Purpose: The purpose was to determine whether the elapsed time from start of a nonblinded treatment period to episode enrollment date in a cluster-randomized crossover trial is associated with compliance to either a period of brief cardiopulmonary resuscitation (CPR) with electrocardiogram (ECG) rhythm analysis or a period of longer CPR with a delayed ECG rhythm analysis in patients with out-of-hospital cardiac arrest.
