Abstract: Disclosed herein are embodiments of systems, methods, and products comprises an analytic server, which provides stateless decision support for clinical evaluation. The analytic server receives clinical evaluation process model from a domain expert and converts the process model into logical expressions of a decision tree. The analytic server dynamically identifies the data referenced in the process and retrieves the referenced data from external databases. The analytic server generates a stateless decision tree comprising the local expressions and the referenced data. The analytic server receives a request comprising patient data and patient needs and preferences. The analytic server determines a decision tree based on the contents of the request. The analytic server evaluates the patient against the decision tree and determines the evaluation results.
