Non-RN providers, like Licensed Practical Nurses (LPNs), could potentially assist with tasks traditionally assigned to RNs. To improve the front-end ED process, we implemented an Attending Physician-Licensed Practical Nurse Team (PNT) positioned next to triage and utilized existing ED hallway space.</p><p><strong>Methods: </strong>This study took place at a tertiary care ED with over 110,000 annual visits. We compared postintervention (Post-PNT) data (11/1/22-2/28/23) to pre-intervention (Pre-PNT) data (7/31/22-10/31/22). The PNT, positioned adjacent to triage, expedited care for ED patients awaiting open rooms.

Post-PNT consisted of 2454 PNT visits and 10834 non-PNT visits. The intervention led to significant improvements, including a decrease in mean ED LOS from 492 to 425 minutes, decrease in 72-hour revisits from 5.1% to 4.0%, decrease in Left Without Being Seen from 6.7% to 3.3%, and decrease in mean Arrival-to-Provider time from 74 minutes to 60 minutes.
