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.

Abstract: Certain exemplary embodiments comprise a method for associating a diagnostic code to a record of a patient visit, the method comprising receiving a visit record comprising a first diagnostic code derived by using a first assignment system, retrieving rules for processing the visit record to determine a second diagnostic code compatible with a second assignment system, processing the visit record and the first diagnostic code using rules to provide the visit record comprising the second diagnostic code, and initiating communication of the visit record including the second diagnostic code compatible with the second assignment system to a destination system.
