Emergency Department Impact Status Scorecard


The ED Impact Status Scorecard is a novel system stress indicator that allows hospitals to communicate real-time facility capacity. This system facilitates the ongoing partnership between hospitals, EMS providers, and County EMS.

For EDs experiencing capacity stresses, the Impact Scorecard allows for a standardized, objective calculation for staff to communicate their current situation. Staff should submit updates through the LEMSIS Resource Bridge ED Impact Status field whenever the internal situation changes. Scores that have not been updated within 4 hours will not be considered accurate.

County EMS continues to work with all system partners to develop automated, real-time, actionable, and informative data sources to improve coordination and patient care. Timely Impact Status Scorecard data will inform decisions regarding County Ambulance Diversion. The County EMS Duty Officer will evaluate Scorecard data, along with other metrics, when evaluating systemwide capacity strain.

    Internal Disaster Declaration: A hospital cannot accept any patients through the 9-1-1 system because of a critical disruption of the ability to provide medical services (e.g., due to structural failures, infrastructure disruptions, or health and safety threats). Upon notification of an Internal Disaster, County EMS and HHSA PHPR can begin processes to evacuate the declaring hospital and distribute patients to other facilities.  Internal Disaster notifications are immediately distributed to MHOAC, RDMHC, CDPH, Fire OAC, 9-1-1 Communication Centers, Private Ambulance Agencies, and HASD&IC.
