Capacity of Tier 2/3 CAMHS and Service Specification: A Model to Enable Evidence Based Service Development.

This paper proposes a model to analyse the 'needs' of any given CAMHS tier 2/3 service catchment area and establish the service capacity/workforce required to deliver 'evidence based practice' that is in keeping with good clinical governance. The key point is that in order to provide 'evidence based' practice and keep within good guidance, we need 'Evidence Based Service Development'. This includes appropriate corporate governance linked to evidence based data to ensure effective commissioning of services based on the evidence of 'what works for whom'.
