Abstract

Systems, devices and methods for triaging health-related data, such as significant health-related events associated with health-related parameters, are disclosed. One aspect is a method for use in managing a patient'"'"'s health within a patient management system. In various embodiments of the method, a number of predetermined events are accessed. The events are related to the patient'"'"'s health and are identified by the patient management system. Each of the predetermined events are classified according to severity using a color-code system. In various embodiments, a red event is an imminent life threatening event, a yellow event is a serious health-related condition that is not imminently life threatening, and a green event is an event that is neither an imminent life threatening event nor a serious health-related condition. Other aspects and embodiments are provided herein.

Claims

classifying each of the number of predetermined events according to severity using a color-code system, wherein classifying each of the number of predetermined events according to severity includes classifying each of the number of predetermined events as imminently life threatening, or as serious but not imminently life threatening, or as neither imminently life threatening nor serious, wherein classifying is performed in the IMD or the portable external device and wherein classifying includes;

identifying events that are imminently life threatening as red events, and automatically initiating a first communication to inform the patient and a second communication to inform a physician of each of the red events, wherein the red events include at least one of;

a lead with an impedance that is out of bounds;

a situation where a therapy provided by the IMD has been exhausted,

an end-of life indicator reflecting a diminishing amount of power remaining for the IMD that is approaching a threshold where therapy will cease; and

a failure of the IMD that prevents delivery of life sustaining therapy;

identifying events that are serious but not imminently life threatening as yellow events, and automatically initiating a process to inform the patient or a physician of each of the yellow events, wherein the yellow events include at least one of;

an elective-replacement indicator for a battery of the IMD;

an atrial lead with an impedance that is out-of bounds;

a detected first instance of a predetermined arrhythmia;

an arrhythmia treatment;

a failure of the IMD that will not prevent delivery of life sustaining therapy;

or

a time in atrial fibrillation; and

identifying events that are neither imminently life threatening nor serious as green events and not automatically initiating communication to inform at least one of the patient and a physician of the green event.

2. The method of claim 1, further comprising automatically performing a system action for the red events.

3. The method of claim 1, wherein automatically initiating a first communication and a second communication includes at least one of calling the physician, calling an answering service of the physician, and paging the physician.

4. The method of claim 1, wherein automatically initiating the process to inform the patient or the physician of the yellow event includes automatically initiating a process to send a message to inform a physician of the yellow event.

5. The method of claim 4, wherein automatically initiating the process to inform the patient or the physician of the yellow event further includes notifying the patient when the physician indicates that the yellow event requires action by the patient.

6. The method of claim 1, further comprising acquiring a number of health-related parameters not acquired using the IMD using the patient management system in addition to the at least one health-related parameter acquired by the IMD, and identifying an occurrence of at least one of the predetermined events based at least in part on the number of health-related parameters.

10. The method of claim 1, wherein the patient management system includes more than one IMD adapted to acquire health-related parameters.

7. A device, comprising a non-transitory machine-readable medium comprising instructions, which when implemented by one or more processors perform the following operations:

accessing a number of predetermined events related to a patient'"'"'s health identified by a patient management system, wherein the patient management system includes an Implantable Medical Device (IMD) and further includes at least one portable external device configured to communicate with the IMD, wherein the IMD is configured to be implanted in an ambulatory patient, and wherein the at least one portable external device is configured to communicate with the IMD when the patient is away from a clinical setting, and wherein the number of predetermined events are identified using at least one IMD-acquired health-related parameter; and

communicating with the data input module and automatically coding each of the number of predetermined events according to severity to prioritize processing of the number of predetermined events, wherein automatically coding is performed in the IMD or the portable external device and wherein automatically coding includes;

automatically classifying events as events that are imminently life threatening, events that are serious but not imminently life threatening, and events that are neither imminently life threatening nor serious;

coding events that are imminently life threatening with a red code, and thereupon informing the patient of the life threatening event using a first communication and informing a physician of the life threatening event using a second communication, wherein the events that are coded with the red code include;

a lead with an impedance that is out of bounds;

a situation where a therapy provided by the IMD has been exhausted;

an end-of life indicator reflecting a diminishing amount of power remaining for the IMD that is approaching a threshold where therapy will cease; and

a failure of the IMD that prevents delivery of life sustaining therapy;

coding events that are serious but not imminently life threatening with a yellow code, and thereupon informing the patient or a physician of the serious event, wherein the events that are coded with the yellow code include;

an elective-replacement indicator for a battery of the IMD;

an atrial lead with an impedance that is out-of bounds;

a detected first instance of a predetermined arrhythmia;

an arrhythmia treatment;

a failure of the IMD that will not prevent delivery of life sustaining therapy;

a time in atrial fibrillation; and

coding events that are neither imminently life threatening nor serious with a green code.

8. The device of claim 7, wherein the operations include automatically performing a system action based on whether an event is coded as imminently life threatening, serious or neither imminently life threatening nor serious.

9. The device of claim 7, wherein the operations include communicating the serious health-related conditions to a physician, and communicating the serious health-related event to the patient if the physician indicates that intervention by the patient is required.

12. The device of claim 7, wherein the patient management system includes more than one IMD adapted to acquire health-related parameters.

11. A method for use in managing a patient'"'"'s health within a patient management system, comprising:
