A Delphi process of emergency medical services (EMS) professionals in another system developed the following categories of prehospital treatment representing increasing acuity, which were adapted for this study: advanced life support (ALS) intervention, ALS\u2013Stat, and ALS\u2013Critical. The sensitivities and specificities of MPDS priority for level of prehospital intervention were determined for each MPDS category.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X00008244_sec03\" sec-type=\"results\"><jats:title><jats:bold>Results:<\/jats:bold><\/jats:title><jats:p>A total of 65,268 patients met inclusion criteria, representing 61% of EMS calls during the study period. The overall sensitivities of high-priority dispatch codes for ALS, ALS-Stat, and ALS-Critical interventions were 83% (95% confidence interval 83\u201384%), 83% (82\u201384%), and 94% (92\u201396%). Overall specificities were: ALS, 32% (31\u201332%); ALS-Stat, 31% (30\u201331%); and ALS-Critical 28% (28\u201329%). Compared to calls assigned to a low priority, calls with high-priority dispatch codes were more likely to receive ALS interventions by 22%, ALS-Stat by 20%, and ALS-Critical by 32%. A low priority dispatch code decreased the likelihood of ALS interventions by 48%, ALS-Stat by 45%, and ALS-Critical by 80%. Among high-priority dispatch codes, the rates of interventions were: ALS 26%, ALS-Stat 22%, and ALS-Critical 1.5%, all of which were significantly greater than low-priority calls (<jats:italic>p<\/jats:italic> &lt;0.05) [ALS 13%, ALS-Stat 11%, and ALS-Critical 0.2%]. Major MPDS were categories with high sensitivities (&gt;95%) for ALS interventions included breathing problems, cardiac or respiratory arrest\/death, chest pain, stroke, and unconscious\/fainting; these categories had an average specificity of 3%. Medical Priority Dispatch System categories such as back pain, unknown problem, and traumatic injury had sensitivities for ALS interventions &lt;15%.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X00008244_sec04\" sec-type=\"conclusion\"><jats:title><jats:bold>Conclusions:<\/jats:bold><\/jats:title><jats:p>The MPDS is moderately sensitive for the Delphi process derived ALS, ALS-Stat, and ALS-Critical intervention levels, but non-specific. A low MPDS priority is predictive of no prehospital intervention.
