1. A system, comprising:
at least one data processor; and
at least one memory storing instructions which, when executed by the at least one data processor, result in operations comprising:
identifying an activity pattern associated with a first clinician as being an infrequent activity pattern that occurs below a threshold frequency, wherein the infrequent activity pattern is identified based at least on a signal-to-noise ratio associated with the infrequent activity pattern being below a threshold value;
determining, based at least on one or more data models, whether the infrequent activity pattern corresponds to an anomalous behavior;
triggering an investigative workflow in response to the infrequent activity pattern being determined to correspond to the anomalous behavior; and
causing a wasting station to provide a separate receptacle for unused medication from the first clinician, wherein the separate receptacle isolates the unused medication that the first clinician disposes of at the wasting station from a shared receptacle that comingles unused medication disposed by multiple clinicians.
