Abstract

Introduction:

A multitude of life-threatening and nonlife-threatening processes cause chest pain and shortness of breath. Prehospital therapy for these patients may be lifesaving and includes pharmacologic interventions, as well as invasive procedures. Appropriate therapy depends on the diagnostic skills of the paramedic.

Objective:

This study was undertaken to determine the accuracy of the paramedic diagnosis in patients transported with a chief complaint of pain or shortness of breath.

Setting:

Multihospital, one large municipal hospital, one community hospital.

Design:

Prospective, cross-sectional study. Paramedics evaluated the patient and then completed a standard form indicating the diagnosis. The paramedic's and final emergency physician's diagnoses were compared to assess the accuracy of the paramedic diagnosis.

Population:

All patients who complained of chest pain or shortness of breath, transported to the study centers by the city of Denver paramedia, were eligible for the study. Ninety-nine of the 102 patients enrolled had complete records for analysis and were entered into the study.

Results:

Diagnostic concordance data were analyzed by organ system (e.g., cardiac, pulmonary, etc.) and for specific diagnoses using the kappa statistic and McNemar's chi-square analysis for discordant pairs. Using the kappa statistic, there was statistically significant concordance between the paramedic and emergency-physician diagnosis for cardiac (p = 0.0001; kappa value = 0.54) and pulmonary organ systems (p = 0.0001; kappa value = 0.61). Overall, for organ system diagnosis, the paramedics had an 82% accuracy (p = 0.05) rating. For specific cardiac and pulmonary diagnosis, paramedics had good concordance with emergency physicians.

Conclusions:

Overall, paramedia have excellent diagnosis by organ system. They retained good agreement on specific cardiac diagnoses and pulmonary diagnosis.
