Abstract

Claims (50)

1 . A treatment plan management system, comprising:

a drug delivery device operable to expel a drug according to a programmed drug treatment plan;

an analyte sensor operable to measure analytes in blood of a patient and output signals related to analyte measurement values of the measured analytes;

a controller operable to provide control commands to the drug delivery device, receive inputs from the drug delivery device and the analyte sensor, and execute an attrition prevention application; and

a server communicatively coupled with the controller and a data storage and operable to execute an attrition prevention engine, wherein the server executing the attrition prevention engine is operable to:

receive status signals from the controller;

compare the received status signals to status signals stored in the data storage;

based on a result of the comparing, generate a notification indicating a response to be generated by the attrition prevention engine; and

forward the notification to the attrition prevention application for implementation of the response.

2 . The system of claim 1 , wherein the received status signals include usage information related to analyte measurement values, information related to delivery of the drug to the patient, and information related to patient interactions with the programmed drug treatment plan.

3 . The system of claim 1 , wherein the analyte sensor further comprises:

a blood glucose detector, wherein an analyte measurement value is a blood glucose measurement value.

4 . The system of claim 1 , wherein the drug delivery device includes:

a processor,

a memory storing programming code executable by the processor,

a drug container configured to contain a liquid drug,

a pump drive mechanism operable to expel the liquid drug from the drug container, and

a communication device coupled to the processor and operable to wirelessly communicate with one or more devices.

5 . The system of claim 4 , wherein

the processor is operable when executing the programming code to:

establish a wireless communication link via the communication device with the controller; and

output measurement values obtained by the analyte sensor via the communication device for delivery to the controller via the wireless communication link.

6 . The system of claim 1 , wherein the analyte sensor includes:

a transceiver operable to wirelessly communicate with the drug delivery device and other devices;

one or more detectors respectively operable to measure parameters related to one or more analyte of the patient; and

logic circuitry coupled to the transceiver and the one or more detectors, the logic circuitry operable to control the analyte sensor and the transceiver.

7 . The system of claim 1 , wherein the server is operable when comparing the received status signals to previously-received status signals stored in the data storage to:

identify a match between the received signals and a set of signals in the previously-received status signals;

locate instructions in the data storage that correspond to the set of previously-received status signals identified as matching the received signals; and

use the instructions in the generation of the notification and the indicated response.

8 . The system of claim 7 , wherein the server is further operable when executing the programming code to:

receive a request for details of the indicated response from the controller; and

provide the details of the indicated response to the controller.

9 . The system of claim 1 , wherein the controller further comprises:

a controller processor, a memory, a communication device and a user interface, wherein the user interface is operable to present information and receive the inputs to the controller and the controller processor is operable to:

output to the user interface a user notification with resource information;

receive via the user interface a selection of a contact within the resource information;

in response to the selection, implement a communication session via the communication device; and

based on a result of the communication session, modify drug delivery settings of the drug delivery device, wherein the modified drug delivery settings are selected based on a likelihood of achieving a patient's target blood glucose levels and improving a time in range of a blood glucose target of the patient.

10 . The system of claim 9 , wherein the controller processor is further operable, when modifying the drug delivery settings of the drug delivery device, to:

adjust basal rate doses or bolus doses of the liquid drug.

11 . The system of claim 9 , wherein the controller processor is further operable to:

determine a basal rate dose that given information obtained from the received status signals is intended to achieve a target blood glucose level for the patient and increase an amount of time in range of the target blood glucose level; and

cause delivery of the determined basal rate dose when controlling the drug delivery device according to the modified drug delivery settings.

12 . The system of claim 9 , wherein the controller processor is further operable to:

determine a bolus dose that given information obtained from the received status signals is intended to achieve a target blood glucose level for the patient and increase an amount of time in range of the target blood glucose level; and

cause delivery of the determined bolus dose when controlling the drug delivery device according to the modified drug delivery settings.

13 . The system of claim 9 , wherein the controller processor is further operable to:

determine both a basal rate dose and a bolus dose that given information obtained from the received status signals are intended to achieve a target blood glucose level for the patient and increase an amount of time in range of the target blood glucose level; and

cause delivery of the determined basal rate dose and determined bolus dose when controlling the drug delivery device according to the modified drug delivery settings.
