Impact of Helicopter Emergency Medical Services on endovascular thrombectomy delays, clinical outcomes, and societal costs in large vessel occlusion stroke: a retrospective registry based counterfactual simulation study
Prioritize implementing simultaneous dispatch protocols when considering HEMS for LVO stroke patients, as secondary dispatch delays undermine the primary advantage of rapid transport time. Remember that on-scene critical care needs must also factor into the overall utility assessment; it's not just about getting there fast. This suggests workflow optimization around dispatch timing might yield more tangible improvements than solely focusing on air assets.
This retrospective simulation study assessed the role of Helicopter Emergency Medical Services (HEMS) in managing large vessel occlusion (LVO) stroke, looking at everything from logistical advantages to potential cost savings. The authors concluded that while HEMS certainly provides a valuable transit advantage for these acute strokes, this benefit isn't absolute and is significantly modulated by two key factors: the level of critical care needed on scene and how quickly the dispatch process occurs. Notably, they found that using a secondary dispatch system actually negates much of the time savings expected from air transport. Therefore, optimizing the prehospital workflow to achieve simultaneous dispatch appears crucial for realizing both maximal clinical benefit and economic efficiency.
