Abstract

Systems and methods have been developed to increase user compliance and adherence to various devices and services including respiratory therapy devices, exercise equipment, and online or other software services. For instance, in some examples the disclosed technology may monitor usage data output from a respiratory therapy device, exercise equipment or computer software program to determine, based on the trends of usage, when a user is likely to terminate or reduce usage within a specified time window. Flagging a user may also trigger further actions to automatically intervene before the user terminates engagement with the service.

Claims (45)

1. A system for predicting compliance, the system comprising:

a device configured to output usage data, the device including a respiratory therapy device;

a memory containing machine readable medium comprising machine executable code having instructions stored thereon; and

a control system coupled to the memory and comprising one or more processors, the control system configured to execute the machine executable code to cause the control system to:

receive, from the device, a set of usage data for a session for a user;

identify a set of previously stored usage data for the user within a past time window, the past time window being split into a first duration and a second duration;

process the set of usage data and the set of previously stored usage data with an algorithm to determine a likelihood the user is to reduce usage of the device within a future time window, the algorithm including a regression model with respective coefficients scaling respective inputs to the regression model such that the regression model combines the scaled respective inputs to determine the likelihood the user is to reduce usage, the regression model having a plurality of features as inputs, the features including an average hours of usage of the device during the first duration and an average hours of usage of the device during the second duration;

determine the user is likely to reduce usage based on if the determined likelihood being above a predetermined threshold; and

adjust a setting on the device for lowering the likelihood, the setting being determined from an identified issue associated with the user and the device, wherein adjusting the setting includes (i) reducing an initial pressure on a ramp feature of the respiratory therapy device, and/or (ii) increasing a humidification level associated with the respiratory therapy device.

2. The system of claim 1 , wherein the usage data is output after each time a user completes a session.

3. The system of claim 1 , wherein the usage data comprises total time of use for a session, and date and time stamp data.

4. The system of claim 1 , wherein the likelihood the user is to reduce usage comprises the likelihood the user is to reduce usage below a threshold amount of time per week.

5. The system of claim 1 , wherein the algorithm pre-processes usage data to determine (i) non-usage days, (ii) standard deviation of hours of usage, (iii) a weekly trend of non-usage days, (iv) a weekly trend of average hours of usage, (v) a weekly trend of standard deviation of hours of usage, or (vi) any combination thereof.

6. The system of claim 1 , wherein executing the machine executable code further causes the control system to output an indication that the user is likely to reduce usage.

7. The system of claim 1 , wherein the device further includes a user interface for a software program.

8. The system of claim 1 , wherein the usage data comprises intensity, length, or frequency.

9. The system of claim 6 , wherein the indication is an alarm or a notification on a user device.

10. The system of claim 6 , wherein the indication depicts selectable alternative therapies to the user on a display, and wherein each of the selectable alternative therapies is associated with a respective set of therapy settings for the respiratory therapy device.

11. The system of claim 10 , wherein the control system is further configured to:

receive a user input associated with a selected one of the selectable alternative therapies; and

cause the respiratory therapy device to change its therapy settings based at least in part on the received user input.

12. The system of claim 10 , wherein the selectable alternative therapies to the user includes at least an option to gradually increase therapy pressure.

13. The system of claim 10 , wherein the control system is further configured to:

determine whether the usage data has been received in a particular time window; and

if the control system determines no usage data has been received within the time window, store non-usage data referenced to that time window.

14. The system of claim 13 , wherein the time window is a twenty-four hour time period.

15. The system of claim 6 , wherein the indication depicts selectable alternative patient interfaces to the user on a display.

16. The system of claim 15 , wherein the control system is further configured to:

receive a user input associated with a selected one of the selectable alternative patient interfaces; and

send, to a remote external device, instructions to purchase and deliver the selected one of the selectable alternative patient interfaces to the user.

17. A non-transitory machine readable medium having stored thereon instructions for performing a method comprising machine executable code which when executed by at least one machine, causes the machine to:

receive a set of usage data for a session for a user, wherein the usage data is usage data of a device including a respiratory therapy device;

identify a set of previously stored usage data for the user within a past time window, the past time window being split into a first duration and a second duration;

process the set of usage data and the set of previously stored usage data with an algorithm to determine a likelihood the user is to reduce usage of the device within a future time window, the algorithm including a regression model with respective coefficients scaling respective inputs to the regression model such that the regression model combines the scaled respective inputs to determine the likelihood the user is to reduce usage, the regression model having a plurality of features as inputs, the features including an average hours of usage of the device during the first duration and an average hours of usage of the device during the second duration;

determine that the user is likely to reduce usage based on the determined likelihood being above a predetermined threshold; and

adjust a setting on the device for lowering the likelihood, the setting being determined from an identified issue associated with the user and the device, wherein adjusting the setting includes (i) reducing an initial pressure on a ramp feature of the respiratory therapy device, and/or (ii) increasing a humidification level associated with the respiratory therapy device.

18. A method of predicting compliance comprising:

receiving, from a device, a set of usage data for a user of the device, the set of usage data including usage data for a first duration and usage data for a second duration, the device including a respiratory therapy device;

retrieving, from a database, profile data of the user;

processing the set of usage data and the profile data with an algorithm to determine a likelihood the user is to reduce usage of the device within a future time window, the algorithm including a regression model with respective coefficients scaling respective inputs to the regression model such that the regression model combines the scaled respective inputs to determine the likelihood the user is to reduce usage, the regression model having a plurality of features as inputs, the features including an average hours of usage of the device during the first duration and an average hours of usage of the device during the second duration;

determining that the user is likely to reduce usage based on the determined likelihood being above a predetermined threshold; and

adjusting a setting on the device for lowering the likelihood, the setting being determined from an identified issue associated with the user and the device, wherein adjusting the setting includes (i) reducing an initial pressure on a ramp feature of the respiratory therapy device, and/or (ii) increasing a humidification level associated with the respiratory therapy device.

19. The method of claim 18 , wherein:

the profile data comprises (i) the user's age, (ii) a type of respiratory therapy device, (iii) the user's healthcare provider, or (iv) a combination thereof, and

the usage data comprises (i) the user's therapy settings, (ii) sensor readings outputted from the respiratory therapy device, or (iii) a combination of both.
