A patient interface for a therapy system allows a patient to input information that characterizes at least one patient event or condition and from which therapy information can be determined. The patient interface may illustratively be formed by developing a patient model that is configured to simulate the patients physiological response to the at least one patient event or condition, collecting patient-specific information over time that relates to actual occurrences of the at least one patient event or condition, and defining a graphical interface, based on the patient model and on the collected patient-specific information, that maps input from the patient of the information that characterizes the at least one patient event or condition to corresponding therapy information.
