The Predictive Risk Stratification Model - or Prism - pilot project has developed and tested a web-based tool, using GP, PEDW, Outpatient, demographic and deprivation 2005 index data. In the first instance the predictive model aims to predict the risk of an individual being admitted to hospital as an emergency admission within the following 12 months.
Risk stratification tools enable a patient population to be stratified by levels of risk. In the past risk has been identified using clinical opinion, threshold modelling or predictive modelling, with predictive modelling being considered the most effective method. The Prism tool stratifies patient populations into four tiers of risk, based on individuals' increasing risk of emergency admission to hospital.
