Abstract
Systems and methods for monitoring accurate, real-time medicament device events, performing analytics on that data, and providing notifications are described. In various embodiments, an application server receives controller medication events, analyzes the events, associated event times, and controller medication dosage plans to characterize event times and send notifications for future doses. The controller medication dosage plan may specify a dose time for a planned dose, a narrow time window comprising the dose time, and an expanded time window comprising the narrow time window and longer in duration than the narrow time window, and the events may be characterized based on their time relative to the dose time, the time windows, and other events.
Core Innovation
The document describes an adherence analytics system for medicament devices that collects real-time rescue/controller medication usage events recorded at first and second recorded times. The system determines whether each recorded time is within a time window inclusive of a scheduled time for a planned dose specified in a controller medication dosage plan.
In response to determining that the first recorded time and the second recorded time are not within the time window, the system determines whether the first recorded time or the second recorded time is closer to the scheduled time. In response to determining that the second recorded time is closer to the scheduled time, the system recharacterizes the first medication usage event as an excessive dose and characterizes the second medication usage event as an off-schedule dose.
The system generates a notification indicative of the characterization of the first medication usage event as an excessive dose and the second medication usage event as the off-schedule dose. The notification is presented on a display of a computing device associated with the medicament device, and the disclosed logic supports patient and healthcare provider interaction through dashboards, adherence information, missed dose workflows, and re-notification when event data is missing due to connectivity or device errors and sync-status uncertainty.
Claims Coverage
The independent claim set includes three independent claims. Across these claims, the inventive coverage centers on comparing two medication usage event times to a time window inclusive of a scheduled time in a controller medication dosage plan, conditionally recharacterizing the events based on which time is closer to the scheduled time, and generating and presenting an indicative notification.
Time-window comparison to controller scheduled dose
receiving a first medication usage event by a medicament device recorded at a first recorded time and a second medication usage event by the medicament device recorded at a second recorded time; determining whether the first recorded time is within a time window inclusive of a scheduled time for a planned dose specified in a controller medication dosage plan; determining whether the second recorded time is within the time window.
Closest-to-scheduled-time recharacterization of events
in response to determining that the first recorded time and the second recorded time are not within the time window, determining whether the first recorded time or the second recorded time is closer to the scheduled time; in response to determining that the second recorded time is closer to the scheduled time, recharacterizing the first medication usage event as an excessive dose, and characterizing the second medication usage event as an off-schedule dose.
Generating and presenting notification indicative of recharacterization
generating a notification indicative of the characterization of the first medication usage event as an excessive dose and the second medication usage event as the off-schedule dose; presenting the notification on a display of a computing device associated with the medicament device.
Sensor-based detection of medication usage events
a medicament device sensor comprising one or more sensors configured to detect usage of the medicament device as one or more medication usage events.
The claims cover an adherence analytics approach where medication usage event times are evaluated against an inclusive scheduled-dose time window in a controller medication dosage plan. When both event times are outside the window, the system determines which recorded time is closer to the scheduled time, recharacterizes the other as an excessive dose and characterizes the closer one as an off-schedule dose, and generates and presents a corresponding notification on a computing device display.
