Ambulance Distribution Model
This Operational Directive outlines a revised model for the distribution of ambulances in metropolitan Western Australia.
Ambulance distribution is currently monitored by the Ambulance Network Coordinators at St John Ambulance Australia (SJAA) and the Ambulance Distribution Coordinators (ADCs) at an Area Health Service Level, on a daily basis across the three existing adult tertiary hospitals using the following percentages: RPH 40%, SCGH 35% and FH 25%.
Under the new model, the following initial high level decision steps direct the allocation of ambulance to an appropriate hospital emergency department (ED).
CLINICIAL SERVICE MATRIX
This matrix provides information on where to take patients who have various clinical indications. This includes recent medical/surgical admission for a related complaint only. The matrix is expected to reduce the frequency of transfers of patients who are taken to a hospital which does not have the appropriate service required for the patient’s condition and/or history.
Thresholds are a guide to the maximum number of ambulances in attendance at a site, allowing for consideration by ADCs of ambulances which are in transit. These thresholds are based on approximate current utilisation and ranking. The thresholds are a ‘live’ measure that will assist SJA to allocate ambulances appropriately. They will not be used to trigger a diversion.
The existing distribution percentages have been reviewed, taking into consideration the closing of Fremantle Hospital Emergency Department, the downsizing of RPH, and the opening of FSH Emergency Department. The proposed new distribution is SCGH 32%, FSH 31%, RPH 21% and Joondalup Health Campus 16%. Note the addition of Joondalup to the distribution percentages. These percentages are to be monitored on a weekly rather than a daily basis as under the present model.
The model (including matrix, thresholds and percentages) will be reviewed at regular intervals and will be specified in the contract between SJAA and WA Health to ensure appropriateness.
The Ambulance Distribution Coordinators (ADC) will continue to have oversight of ambulance distribution as per the new model, and will remain the sole point of contact between WA Health and SJA regarding distribution and diversion in the metropolitan area.
