Evaluation of paramedic programs using outcomes of prehospital resuscitation for cardiac arrest.
Two evaluation methods, one statistical and one comparative, were developed to assess the effectiveness of paramedic programs in King County, Washington. The outcome of hospital admission following prehospital cardiac arrest was used as a measure of effectiveness. In the statistical method, actual outcomes were compared with predicted outcomes. Predictive variables for admission were time from collapse to initiation of cardiopulmonary resuscitation and time from collapse to definitive care. Given knowledge of the predictive variables, the statistical evaluation enabled us to determine the probability of the outcome following cardiac arrest. In the comparative method, outcomes were compared with a standard in an adjacent community. Using this method, we identified program elements that could lead to improved outcome. Both evaluation methods are easily implemented.
