Background The effect of transdermal glyceryl trinitrate (GTN, a nitrovasodilator) on clinical outcome when administered before hospital admission in suspected stroke patients is unclear. Here, we assess the safety and efficacy of GTN in the prespeci...

Objectives
Ambulances offer the first opportunity to evaluate hyperacute stroke treatments. We investigated the conduct of a hyperacute stroke study in the ambulance-based setting with a particular focus on timings and logistics of trial delivery....

Background: Prehospital stroke trials will inevitably recruit patients with non-stroke conditions, so called stroke mimics. We undertook a pre-specified analysis to determine outcomes in patients with mimics in the second Rapid Intervention with Glyc...

Introduction: Stroke is a severe condition with high morbidity and mortality. Despite treatment effects in acute stroke being predominantly time dependent (e.g. thrombolysis and thrombectomy), proven treatments are hospital based and require prior br...

Background

We sought to understand the main ethical considerations when conducting clinical trials in the prehospital ambulance based setting.

Methods

A systematic review of the literature on randomised controlled trials in ambulance setting... Read More about Assessment of consent models as an ethical consideration in the conduct of prehospital ambulance randomised controlled clinical trials: a systematic review.
