Paramedic determination of appropriate emergency department destination.

BACKGROUND

Freestanding emergency departments (FSED) are equipped to care for most emergencies, but do not have all the resources that hospital-based emergency departments (ED) offer. As the number of FSEDs grows rapidly, emergency medical services (EMS) must routinely determine whether a FSED is an appropriate destination. Inappropriate triage may delay definitive care, potentially increasing morbidity, mortality, and resource utilization. We sought to evaluate paramedics' ability in determining whether a FSED is the most appropriate destination.

METHODS

We conducted a retrospective study of two county EMS agencies and two FSEDs over a 25-month period in Alachua and Levy County, Florida, USA. Both EMS agencies allow paramedic discretion in determining transport destination. To determine whether paramedics can correctly identify patients that can be cared for fully at a FSED, our primary outcome was the percentage of patients transported to FSEDs by EMS that were discharged without additional hospital-based resources.

RESULTS

We identified 1247 EMS patients that had a selected destination of FSED. We excluded patients that did not arrive at their selected FSED destination, left before FSED disposition, or were transferred from the FSED to unaffiliated hospitals. A total of 1184 patients were included for analysis, and 885 (74.7%) did not require additional hospital resources. Comparing the two EMS agencies yielded similar results.

CONCLUSION

In this study, involving two EMS agencies over a 25-month period, we found that 3 out of 4 patients deemed appropriate for transport to a FSED by a paramedic did not require additional hospital-based services.
