I would like to know the reason why someone is always doing a study in the ALS vs BLS survival rates on a given situation or Pt presentation. Is there a body out there somewhere that has an axe to grind with Paramedics? All of the studies I have read recently are saying that BLS survival rates are better for this or that, so why then are we training so many paramedics?
I believe that to have a successful system we have to combine the two. Sure there are geographical and monitary reasons for different levels of service that are provided across the continent, but that is one of the things that makes EMS interesting.
As for the survival rates of the trauma aspect, it is more likely that a BLS unit is going to "scoop and run". I have seen this in my area that sometimes an ALS unit will stay on scene longer than BLS but, yes there are more interventions that they can perform than BLS can.
Also we utilize our Air-Medivac here quite frequently in trauma situations. So during the response ALS will remain on scene to stbilize, intubate, decompress if needed before arrival of the chopper. Whereas the BLS unit would load and go and have the chopper respond to the hosp if travel time warranted, and there was no prolonged extrication required.
I try to guage my traumas to do my utmost in attaining the golden hour. That way I can feel good that I have given my Pt the best chance at surviving.
