Abstract

A healthcare decision support system simulates effects of a change in a number of patients. A repository includes patient specific clinical and non-clinical data, comprising multiple medical record attributes of multiple patients. A simulation processor receives data representing multiple factors for adjusting a value representing number of patients in corresponding multiple associated subsets of the multiple patients. An individual subset comprises patients having a particular medical record attribute of a particular type. A calculation processor identifies patients common to different particular subsets, and calculates a change in a value representing number of patients common to the different particular subsets by calculating a product of factors associated with the different particular subsets.
