A structures, process and outcome evaluation of the Residential Aged care District Assessment and Referral Rapid Response (RADAR RR) model

Older persons from residential aged care homes (RACF) have unique needs that are often overlooked in our traditional emergency departments (EDs). This can lead to under triage, prolonged length of ED stays, unnecessary investigations and iatrogenic hospital acquired complications (1). The Residential Aged Care District Assessment and Referral Rapid Response (RADAR RR) model is a pre-hospital Queensland Ambulance Service (QAS) co-responder model providing ED equivalent care in the resident’s home for acute illness and injury. RADAR RR model operates between 0800 and 2000, 7 days a week. We hope to evaluate the clinical and cost outcomes of the RADAR RR model and determine if it is equivalent to the care provided by traditional ED models of care in an urban setting. We will also review the structures and processes required for effective service delivery which will in turn guide the development of a toolkit to assist other hospitals in adopting the RADAR RR model if appropriate for their area. Finally, given increasing pressure for high value models of care we will undertake an economic evaluation to determine if the RADAR RR model is more economically efficient than the traditional ED model of care.
