An interactive computer assisted method compiles comprehensive health care information on patients in a central repository, assesses and analyzes this information, and identifies high utilizers of health care services using a computer and a user associated therewith. The method includes the steps of creating a central repository of various databases containing patient information, including demographic information and behavior, and optionally the results of a core survey of health status questions. The invention optionally involves the step of determining the appropriate core questions and the criteria to determine whether and when to ask certain questions of particular patients based on their response to prior questions. The invention accurately predicts risk of a medical condition or progression of a medical condition utilizing an interactive administration of a set of core survey questions combined with diagnostic data and places patients efficiently, reliably, and accurately into the appropriate treatment intervention programs. The invention eliminates redundant, repetitive surveying of patients with multiple medical conditions.
