To ask the Scottish Executive what the Operational Research Consultancy (ORCON) standards have been for the Scottish Ambulance Service in each year since 1999, broken down by NHS board area.
Prior to the introduction of the priority-based dispatch system which rolled out across mainland Scotland between August 2002 and April 2004, 999 emergency calls to the Scottish Ambulance Service were dealt with on a “first come first served” basis. The speed of response depended not on the condition of the patient but on the volume of calls being responded to and the ambulance resources available at the time. The performance standards applied by the Scottish Ambulance Service varied according to population density – as with other ambulance services in the United Kingdom. These are known as the ORCON standards. In Scotland, to ensure that the standards reflected local demography, they were applied based on local authority areas. The standards were:
High Density (more than 3.0 persons per acre) – 50% of calls to be responded to within seven minutes and 95% within 14 minutes;
Medium Density (less than 3.0 but more than 0.5 persons per acre) – 50% of calls to be responded to within eight minutes and 95% within 18 minutes;
Sparse Density (less than 0.5 persons per acre) – 50% of calls to be responded to in eight minutes and 95% within 21 minutes.
Under the priority based dispatch system, which is used in all mainland board areas, 999 emergency calls are processed using well proven, clinically approved, screen based software (called Automatic Medical Priority Dispatch System). Based on the responses of the caller, the software assigns the call a response category. The categories and standards applied are:
Category A – clinically defined as “immediately life threatening”. The target is that by March 2008, 75% of such calls should be responded to within eight minutes across mainland Scotland. The ambulance service has phased the introduction of priority based dispatch and is progressing towards this target.
Category B – clinically defined as “not life threatening but still serious”. The target for this category of calls is that 95% should be responded to within either 14, 19 or 21 minutes depending on the population density of the health board.
The ambulance service continues to apply ORCON standards to their responses to calls from NHS Western Isles, NHS Shetland and NHS Orkney.
