The North Wales Demonstrator is currently piloting the Unique Care model of multi-disciplinary team development in four practices - based upon the Castlefields approach to case management. This model includes the use of a validated questionnaire (EARLI) to help identify those at risk of emergency hospital admission. The same practices have also been involved in piloting the PRISM risk stratification tool which also looks to identify patients at risk of emergency admission. This new study will explore user views of both tools, identifying some of their strengths and weaknesses, and comparing the different types of patient identified as at risk. The study should provide findings in late Autumn 2010.
