【 摘 要 】

This was a prospective cross-sectional study of consecutive transported patients by emergency medical service (EMS) to a referral hospital. The goal of this study was the evaluation of emergency medical technician intermediate prediction about their transported patients disposition in Emergency Department of Imam Khomeini Hospital. 2950 patients were transported to this hospital, Questionnaires were submitted in 300 of consecutive patient transports and completed data were obtained and available upon arrival at hospital for 267 of these cases. Emergency medical technicians intermediate (EMT-I) were asked to predict whether the transported patient would require admission to the hospital, and if so, what will be their prediction of patient actual disposition. Their predictions were compared with emergency specialist physicians. EMT-I predicted that 208 (78%) transports would lead to admission to the hospital, after actual disposition, 232 (%87) patients became admitted. The sensitivity of predicting any admission was 65%, with positive predictive value (PPV) of 39% and specificity of 86% with negative predictive value (NPV) of 94%. The sensitivity of predicting trauma patients (56.2% of total patients) was 55% with PPV of 38%, specificity of 86% and for Non-trauma patients' sensitivity was 80% with PPV of 40% and specificity of 82%. EMT-I in our emergency medical system have very limited ability in prediction of admission and disposition in transported patients and their prediction were better in Non-trauma patients. So in our EMS, the pre-hospital diversion and necessity of transporting policies should not be based on EMS personnel disposition.
