1. A computer-implemented method comprising:

  • receiving a request from a user device for medical information that characterizes a group of individuals composed of multiple individuals from a set of de-identified medical data representing pre- or post-encounter characteristics of the individuals;

    producing, by a hardware processor, tokens, wherein the identity of the individuals is unattainable from the tokens, each token being associated with an individual in the group, each token associable with a corresponding token in the set of de-identified medical data, and each token in the set of de-identified medical data being associated with medical data for a corresponding individual;

    producing the requested medical information that characterizes the group of individuals by identifying the tokens in the set of de-identified medical data and the associated de-identified medical data that correspond to the produced tokens, wherein the produced medical information is absent personally identifiable information and has been produced without the individuals in the group having authorized production of such medical information that characterizes the group; and

    providing the produced medical information to report the characteristics of the group of individuals absent authorization from the individuals in the group of individuals.
