Abstract

This document discusses, among other things, patient monitoring systems, apparatus, and methods that change the operation of an ambulatory medical device (AMD) using geographic location information.

Claims

1. A system comprising:

a mobile monitor configured to determine a geographic location; and

an ambulatory medical device (AMD), communicatively coupled to the mobile monitor, the AMD configured to detect physiologic information from the patient using a first monitoring mode and a second monitoring mode,

wherein the AMD is configured to receive the determined geographic location from the mobile monitor,

wherein the AMD is configured to switch between the first monitoring mode and the second monitoring mode according to the determined geographic location, and

wherein the second monitoring mode consumes more power than the first monitoring mode.

2. The system of claim 1, wherein, in response to the determined geographic location indicating that the patient is at a medical care facility, the mobile monitor is configured to instruct the AMD to switch from the first monitoring mode to the second monitoring mode.

3. The system of claim 2, wherein the AMD is configured to switch from the first monitoring mode to the second monitoring mode in response to the determined geographic location indicating that the patient has been at a medical care facility for a period longer than a specified amount of time.

4. The system of claim 1, wherein the first monitoring mode is a pre-hospitalization mode and the second monitoring mode is an in-clinic mode.

5. The system of claim 1, wherein the AMD is configured to switch from the second monitoring mode to a third monitoring mode, different than the first and second monitoring modes, in response to the determined geographic location indicating that the patient is no longer at the medical care facility.

6. The system of claim 1, wherein the mobile monitor is configured to receive user confirmation that the patient is seeking medical attention, and

wherein the AMD is configured to transition from the first monitoring mode to the second monitoring mode in response to the determined geographic location indicating that the patient is at a medical care facility and the mobile monitor receiving user confirmation that the patient is seeking medical attention.

7. The system of claim 1, wherein the AMD includes a risk circuit configured to determine a risk of a worsening medical condition using the detected physiologic information,

wherein the risk circuit, in the first monitoring mode, is configured to determine the risk using a first weighting of detected physiologic information or a comparison of the detected physiologic information to a first threshold, and

wherein the risk circuit, in the second monitoring mode, is configured to determine the risk using a second weighting of detected physiologic information or a comparison of the detected physiologic information to a second threshold, the second threshold different than the first threshold.

8. The system of claim 1, wherein the mobile monitor includes a mobile electronic device configured to receive location information including at least one of global positioning system (GPS), radio frequency identification (RFID), Bluetooth®

, Wi-Fi®

, near-field communication (NFC), cellular network, or paging network location information.

9. The system of claim 1, wherein the mobile monitor, in response to the determined geographic location, is configured to prompt a user to instruct the AMD to upload detected physiologic information to a storage location remote from the AMD.

10. A system comprising:

an ambulatory medical device (AMD) configured to detect physiologic information from a patient and to receive information corresponding to a geographic location of the patient,

wherein the AMD is configured to transition from a first monitoring mode to a second monitoring mode in response to the received information corresponding to the geographic location of the patient indicating that the patient is at a medical care facility,

wherein the AMD, in the first monitoring mode, is configured to detect physiologic information from the patient using a sensor at a first sensitivity or at a first frequency, and

wherein the AMD, in the second monitoring mode, is configured to detect physiologic information from the patient using the sensor at a second sensitivity, more sensitive than the first sensitivity, or at a second frequency, higher than the first frequency.

11. The system of claim 10, wherein the AMD, in the first monitoring mode, is configured to detect or transmit physiologic information from the patient in an ambulatory, pre-hospitalization mode, and

wherein the AMD, in the second monitoring mode, is configured to detect or transmit physiologic information from the patient in an in-clinic mode that consumes more power than the ambulatory mode.

12. The system of claim 10, wherein the AMD is configured to transition from the first monitoring mode to the second monitoring mode in response to the received information corresponding to the geographic location of the patient indicating that the patient has been at the medical care facility longer than a specified amount of time.

13. The system of claim 10, wherein the AMD is configured to transition from the second monitoring mode to a third monitoring mode, different from the first and second monitoring modes, in response to the received information corresponding to the geographic location of the patient indicating that the patient is no longer at the medical care facility.

14. A method comprising:

receiving information corresponding to a geographic location of a patient at an ambulatory medical device (AMD);

detecting physiologic information from the patient using the AMD; and

transitioning the AMD from an ambulatory data collection or transmission mode to an in-clinic data collection or transmission mode in response to the received information corresponding to the geographic location of the patient indicating that the patient is at a medical care facility,

wherein the in-clinic data collection or transmission mode has a higher power consumption than the ambulatory data collection or transmission mode.

15. The method of claim 14, including:

determining a geographic location of a mobile monitor;

prompting, using the mobile monitor, user feedback in response to the received information corresponding to the geographic location of the patient indicating that the patient is at the medical care facility; and

receiving, using the mobile monitor, user confirmation that the patient is seeking medical attention in response to the prompted user feedback,

wherein the receiving information corresponding to the geographic location of the patient at the AMD includes receiving the determined location of the mobile monitor, and

wherein the transitioning the AMD from the ambulatory data collection or transmission mode to the in-clinic data collection or transmission mode includes using the received user confirmation that the patient is seeking medical attention.

16. The method of claim 14, wherein the transitioning the AMD from the ambulatory data collection or transmission mode to the in-clinic data collection or transmission mode includes in response to the received information corresponding to the geographic location of the patient indicating that the patient has been at the medical care facility for a specified amount of time.

17. A system comprising:

an ambulatory medical device (AMD) configured to detect physiologic information from a patient and to receive information corresponding to a geographic location of the patient,

wherein the AMD is configured to transition from a first monitoring mode to a second monitoring mode in response to the received information corresponding to the geographic location of the patient indicating that the patient is at a medical care facility,

wherein the AMD, in the first monitoring mode, is configured to detect physiologic information from the patient using a first set of sensors, and

wherein the AMD, in the second monitoring mode, is configured to detect physiologic information from the patient using a second set of sensors, different than the first set of sensors.

18. The system of claim 17, wherein the second monitoring mode consumes more power than the first monitoring mode.

19. The system of claim 17, wherein the AMD is configured to transition from the first monitoring mode to the second monitoring mode in response to the received information corresponding to the geographic location of the patient indicating that the patient has been at the medical care facility for a period longer than a specified amount of time.

20. The system of claim 17, wherein the first monitoring mode is a pre-hospitalization mode and the second monitoring mode is an in-clinic mode.
