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.

(d) weighting, within the computing device, the measurements of medical device usage for individual usage sessions during the measurement cycle according to a predetermined weighting scheme;

(e) determining, within the computing device, whether a compliance period value for the measurement cycle, is at least equal to the minimum medical device usage compliance value, wherein the compliance period value for the measurement cycle is determined on the computing device as the number of compliance periods in the measurement cycle for which the weighted measurements of medical device usage indicate that the actual medical device usage has satisfied the compliance value, and wherein the weighted measurements of medical device usage indicate actual medical device usage has satisfied the compliance value, for a given compliance period responsive to the sum of the weighted measurements for the usage sessions that occurred during the given compliance period being greater than or equal to the compliance value;

(f) obtaining, at the computing device, a medical device usage prescription value; and

(g) comparing via the computing device, the compliance period value with the medical device usage prescription value.

2. The method of claim 1, wherein the compliance period value is determined as a percentage of compliance periods in the measurement cycle in which the weighted measurements of medical device usage indicate actual medical device usage has satisfied the compliance value.

3. The method of claim 1, further comprising:

(f) obtaining, at the computing device, a measurement cycle compliance value;

(g) comparing, in the computing device, the compliance period value with the measurement cycle compliance value; and

(h) providing a compliance indicator from the computing device based upon results of the comparison.

4. The method of claim 3, wherein the compliance indicator indicates (1) a compliance signal responsive to the compliance period value being at least equal to the measurement cycle compliance value, and (2) a non-compliance signal responsive to the compliance period value being less than the measurement cycle compliance value.

5. The method of claim 3, 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.

6. The method of claim 3, further comprising (i) creating 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 and a measurement cycle compliance value.

7. The method of claim 6, wherein the report is in the form of at least one of a list, a chart, a diagram and a graph.

8. The method of claim 1, further comprising:

(f) obtaining, at the computing device, a compliance warning value;

(g) comparing, in the computing device, the compliance period value with the compliance warning value; and

(h) generating, by the computing device, a warning signal responsive to the comparison of the compliance period value with the compliance warning value.

9. The method of claim 8, wherein the compliance warning value is set by a user.

10. The method of claim 8, wherein the warning signal is an audible alarm, a visual display, or both.

11. The method of claim 8, wherein the warning signal is a visual display and includes an alphanumeric message.

12. The method of claim 11, wherein the alphanumeric message is user-defined.

13. The method of claim 1, wherein the compliance period is a 12-hour period, a 24-hour period, a multi-day period, a weekly period, a multi-weekly period, a monthly period, a multi-monthly period, an annual period, or a multi-yearly period.

14. The method of claim 1, wherein the compliance period is a fixed period of time, a rotating period of time, or a dynamic period of time.

15. The method of claim 1, wherein the measurement cycle is a 12-hour period, a 24-hour period, a multi-day period, a weekly period, a multi-weekly period, a monthly period, a multi-monthly period, an annual period, or a multi-yearly period.

16. The method of claim 1, wherein the medical device is 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.
