In one example, a process includes receiving a plurality of first communications and a plurality of second communications, each first communication capturing activity of a patient using a first device at a different time and each second communication capturing activity of the patient using a second device at a different time. The process includes identifying a macro trend for all monitored activity of the patient based on data taken from the first and second communications. The process includes comparing data taken from a new communication from at least one of the first and second devices to the identified macro trend. A caregiver may be notified according to the comparison.
