Comparative Study
Comparison of the medical priority dispatch system to an out-of-hospital patient acuity score.
Although the Medical Priority Dispatch System (MPDS) is widely used by emergency medical services (EMS) dispatchers to determine dispatch priority, there is little evidence that it reflects patient acuity. The Canadian Triage and Acuity Scale (CTAS) is a standard patient acuity scale widely used by Canadian emergency departments and EMS systems to prioritize patient care requirements. ⋯ The Medical Priority Dispatch System exhibits at least moderate sensitivity and specificity for detecting high acuity of illness or injury. This performance analysis may be used to identify target protocols for future improvements.

Comparative Study
Rewarming rates in urban patients with hypothermia: prediction of underlying infection.
In the urban setting, hypothermia is commonly associated with illness or intoxication, with death often secondary to infection. ⋯ Rewarming rates reflect intrinsic capacity for thermogenesis. Increased RWRs were associated with the absence of infection. The achievement of normothermia did not prevent death in infected patients. Initiation of invasive rewarming in urban patients with hypothermia who have not had hypothermic cardiac arrest may be unwarranted. Management of this population should emphasize support, detection, and treatment of underlying illness.

Some practitioners and investigators have presumed relationships between pain scores and heart rate, blood pressure, or respiratory rate. Previous literature has not adequately addressed the association of pain and vital signs. ⋯ No clinically significant associations were identified between self-reported triage pain scores and heart rate, blood pressure, or respiratory rate.
