摘要
Introduction: In Italy, administration of medications or advanced procedures dictates the prehospital presence of a physician to initiate treatment. Nursing staff is often used as dispatchers in Italian emergency medical ambulance services. There is little data about nursing dispatch performance in detecting high-acuity patients who need prehospital medications and procedures. Objective: To determine the ability of a dispatch center staffed by emergency ambulance nurses to detect prehospital need for physician interventions in the context of a semi-rural area Emergency Medical Services system. Methods: A retrospective analysis of 53,606 calls from the Rovigo Emergency Ambulance Services' database was undertaken. Physician prehospital interventions were defined as the administration of medications or procedures (advanced airway management and ventilation, pneumothorax decompression, fluid replacement therapy, external defibrillation, cardioversion and pacing). The dispatch codes (assigned by a subjective decision-making process as Red, Yellow, or Green) of all transported prehospital patient calls were matched with an out-of-hospital triage system staffed by clinicians to determine the number of correctly identified prehospital need of physician interventions. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results: The sensitivity of subjective experience-based nursing dispatch in detecting the need for physician interventions was 78.0% (95% CI, 76.9%-79.1%), with a PPV of 36.6% (95% CI, 35.8%-37.5%). Specificity was 83.8% (95% CI: 83.4%-84.1%), with an NPV of 96.9% (95% CI, 96.8%-97.1%). Conclusion: A dispatch center staffed by nurses with six years of experience and three months of training correctly identified when not to send a doctor to the scene in the absence of need for physician interventions, using a subjective decision-making process. The nurses staffing the dispatch center also worked in the field. Dispatch center staff were not able to predict when there was no need for physician interventions in high-acuity dispatch code patients, resulting in an over-triage and use of emergency physicians on scene.
