Abstract: A method for gathering medical information sorting it by statistically and medically based rules, and condensing it into a data set which enables medical providers to practice medicine in a more efficient manner. The medical information may be gathered from insurance billing records and patient responses to statistically-validated medical status questionnaires. The patient population may be a defined one, being composed of all patients in a group which is being treated by an individual medical provider or a group of providers at any particular time. The financial transactions to be monitored may be formatted electronically into one or more standard formats as well as medical diagnosis and medical procedure information which has been transmitted in standard codes. These data sets are gathered in electronic format by being copied from the feeder computer system into another computer which does the required rules-based data reduction.
