  • Patent number: 11101026
    Abstract: In some aspects, the present disclosure provides a computer program product for assembling a database comprising electronic data modules, which may be electronic medical records (EMRs). The present disclosure can also be used for purposes such as implementing a system in which physicians and patents can be provided with applications that they can use to confirm that various disease related events have taken place. This can be performed using active diagnosis modules (ADMs) comprising schedules of events. These ADMs and their events can also be used to populate a database which can be used for purposes such as identifying, recruiting and tracking participants in clinical trials.
