Methods, systems, and apparatus, including computer programs encoded on computer storage media, for creating a probabilistic healthcare value profile for a patient. One of the methods includes obtaining a current medical history including multiple current characteristics of a first patient having a first current age, obtaining multiple sets of age-correlated characteristics, each set corresponding to a different second patient, determining, for one or more sets of the age-correlated characteristics, that characteristics in at least a threshold portion of the respective age-correlated characteristics match one of the multiple current characteristics of the first patient, and generating a future probabilistic medical profile of the first patient, the future probabilistic medical profile including an aggregation of at least a portion of the age-correlated characteristics in the one or more sets, the aggregation including at least one non-matching age-correlated characteristic that does not match any of the current characteristics of the first patient.
