EMS ImpactWhile precise numbers are not available, EMS treats and transports approximately 25 to 30 million patients per year. As an important point of entry into the healthcare system, EMS is in a unique position to impact those patients. It is logical to assume that prehospital intervention positively affects patient outcome, but this influence is difficult to quantify. For example, early defibrillation to victims of sudden cardiac arrest,13 administration of nitroglycerin to patients with chest pain,14,15 and prehospital administration of fibrinolytic therapy to patients with myocardial infarction16 measurably saves lives. On the other hand, seemingly logical interventions such as the pneumatic anti-shock garment17 and endotracheal intubation of children18 may in fact cause harm. That so few EMS interventions have been subjected to outcome studies illustrates the lack of evidence for most prehospital therapies. More research is necessary to provide the evidence upon which EMS practices can be based. Misperceptions about EMS on the part of the public abound. In one study, fifteen percent of the patients in a hospital emergency department thought that paramedics were physicians.19 The entertainment media routinely depict cardiopulmonary resuscitation as resulting in good patient outcome, likely leading to unrealistic expectations among the lay public.20 Most members of the public believe that the use of warning lights and sirens saves clinically significant time in ambulance response and transport to the hospital, although several studies have suggested otherwise.21,22 No one has published an evaluation of the public’s perception of the importance of EMS research or the impact of research (or the lack thereof) on EMS practices. |
