Abstract

A computer-implemented method for tracking and monitoring a patient'"'"'s compliance with a medical device usage prescription for a medical device is disclosed. This method and system includes the steps of: (a) providing a minimum medical device usage compliance value for the medical device for a predetermined compliance period; (b) providing the quantity of compliance periods in a measurement cycle; and (c) determining a compliance period value as the number of compliance periods in the measurement cycle in which an actual medical device usage value is at least equal to the minimum medical device usage compliance value. In another embodiment, the method also includes: providing a weighting factor, and applying the weighting factor to at least one actual medical device session usage value.

Claims

1. A method for tracking and monitoring a patient'"'"'s compliance with a prescription for a medical device during a compliance period, the method comprising:

executing one or more computer program modules using one or more processors to cause the one or more processors to;

receive a minimum medical device usage short session value;

determine an actual medical device usage value for at least one discrete medical device usage session associated with a medical device adapted to provide a treatment to a patient;

compare the actual medical device usage value for each medical device usage session with the minimum medical device usage short session value; and

determine an actual medical device usage value for the compliance period by summing the actual medical device usage value for each medical device usage session that is greater than or equal to the minimum medical device usage short session value and subtracting each actual medical device usage value that is less than the minimum medical device usage short session value during the compliance period.

2. The method of claim 1, wherein the one or more processors are further caused to:

apply a weighting factor to the actual medical device session usage value to produce a weighted actual medical device session usage value for the at least one medical device usage session;

wherein summing the actual medical device usage for each medical device usage session includes summing the weighted actual medical device usage values for the medical device usage sessions during the compliance period.

3. The method of claim 2, wherein the weighting factor is variable dependent upon the actual medical device session usage value.

4. The method of claim 3, wherein the weighting factor is in a range from 0 to 1.

5. The method of claim 1, wherein the one or more processors are further caused to:

determine a short session count value based upon the number of usage sessions wherein the actual medical device usage value for the respective usage session is less than the minimum medical device usage short session value.

6. The method of claim 5, wherein the one or more processors are further caused to:

provide a short session warning value to the medical device;

compare the short session count value with the short session warning value; and

provide a warning signal for presentation responsive to the short session count value being equal to the short session warning value.

7. A system configured for tracking and monitoring a patient'"'"'s compliance with a prescription for a medical device during a compliance period, the system comprising:

one or more processors configured to;

monitor an actual medical device usage for at least one discrete medical device usage session associated with a medical device adapted to provide a treatment to a patient;

compare the actual medical device usage value for each medical device usage session with a minimum medical device usage short session value; and

determine an actual medical device usage value for the compliance period by summing the actual medical device usage value for each medical device usage session that is greater than or equal to the minimum medical device usage short session value and subtracting each actual medical device usage value that is less than the minimum medical device usage short session value during the compliance period.

8. The system of claim 7, wherein the one or more processors are further configured to determine a compliance period value as a number of compliance periods in a measurement cycle in which the actual medical device usage value is at least equal to a minimum medical device usage compliance value.

9. The system of claim 8, wherein the one or more processors are further configured to compare the compliance period value with a medical device usage prescription value.

10. The system of claim 8, wherein the one or more processors are further configured to determine the compliance period value as a percentage of compliance periods in the measurement cycle in which the actual medical device usage value is at least equal to the minimum medical device usage compliance value.

11. The system of claim 8, wherein the one or more processors are further configured to:

compare the compliance period value with a measurement cycle compliance value; and

output a compliance indicator based upon results of the comparison.

12. The system of claim 11, wherein the compliance indicator indicates one or both of:

(1) a compliance signal responsive to the compliance period value being at least equal to the measurement cycle compliance value, or (2) a non-compliance signal responsive to the compliance period value being less than the measurement cycle compliance value.

13. The system of claim 11, wherein the compliance indicator indicates a compliance signal, a non-compliance signal, a marginal compliance signal, a warning signal, a trend signal, a compliance value signal, or any combination thereof.

14. The system of claim 11, wherein the one or more processors are further configured to provide a report based upon the compliance indicator and indicative of at least one patient'"'"'s compliance with at least one of a medical device usage prescription value, a minimum medical device usage value, or a measurement cycle compliance value.

15. The system of claim 8, wherein the one or more processors are further configured to:

compare the compliance period value with a compliance warning value; and

provide a warning signal for presentation to a user responsive to the compliance period value being equal to the compliance warning value.

16. The system of claim 7, wherein the medical device includes one or more of a ventilator, a pressure support system, an oximeter, a ventilatory support system, an oxygen concentrator, a nebulizer, a humidifier, a phototherapy device, an immersion therapy device, or a physical therapy device.

17. The system of claim 7, wherein at least one of the one or more processors are resident in the medical device.

18. The system of claim 7, further comprising a communication device associated with the medical device, and wherein at least one of the one or more processors is resident in the medical device and at least one of the one or more processors is resident in the communication device.

19. The system of claim 7, further comprising:

a communication device associated with the medical device; and

a central database remote from the medical device and in communication therewith via the communication device.

20. The system of claim 7, wherein the one or more processors are further configured to apply a weighting factor to the actual medical device session usage value.

21. The system of claim 20, wherein the weighting factor is variable dependent upon the actual medical device session usage value.

22. The system of claim 20, wherein the weighting factor is in a range from 0 to 1.

23. The system of claim 7, wherein the one or more processors are further configured to:

receive the minimum medical device usage short session value; and

determine a short session count value based upon the number of usage sessions wherein the actual medical device usage value for the respective usage session is less than the minimum medical device usage short session value.

24. The system of claim 23, wherein the one or more processors are further configured to:

compare the short session count value with a short session warning value; and

provide a warning signal for presentation to a user responsive to the short session count value being equal to the short session warning value.
