Abstract

A method and system for assessing the health status of a patient, such as the asthma status of a patient, provides an asthma status score and a confidence rating indicative of the score'"'"'s reliability using continuous real-time data. In some embodiments, the assessment comprises a multidimensional analysis in which asthma status scores and respective confidence ratings are generated for multiple individual asthma health dimensions as well as a summary asthma health dimension indicative of overall asthma health. In some embodiments, the individual dimensions include an environmental trigger dimension based on sensor-based environmental data, a physiological burden dimension based on sensor-based physiological data, a medication adherence dimension based on patient diary data and a perceived symptom dimension based on patient diary data.

Claims

1. An assessment system for assessing the asthma status of a patient, comprising:

a data processing system;

an environmental data capture system communicatively coupled with the data processing system, wherein the environmental data capture system is configured to capture environmental sensor data and generate sensor-based environmental data in a form usable by the data processing system based at least in part on the environmental sensor data; and

an asthma data output system communicatively coupled with the data processing system, wherein the data processing system is configured to receive the sensor-based environmental data from the environmental data capture system, generate an asthma status score and a confidence rating for the asthma status score based at least in part on sensor-based environmental data and output the asthma status score and the confidence rating to the asthma data output system, wherein the confidence rating is generated based on at least one of a comparison of an actual number of parameters used to generate the asthma status score with a predefined number of parameters or a comparison of an actual change rate for the asthma status score with a predefined change rate, and wherein the asthma data output system is configured to display the asthma status score and the confidence rating.

2. The assessment system of claim 1, wherein the confidence rating is generated based on a comparison of an actual number of parameters used to generate the asthma status score with a predefined number of parameters and a comparison of an actual change rate for the asthma status score with a predefined change rate.

3. The assessment system of claim 1, wherein the data capture system further comprises a physiological data capture system wherefrom the data processing system is configured to receive sensor-based physiological data and is configured to generate the asthma status score further based at least in part on the sensor-based physiological data.

4. The assessment system of claim 1, further comprising a user input system communicatively coupled with the data processing system, wherein the data processing system is configured to receive from the user input system patient diary data input by the patient and is configured to generate the asthma status score further based at least in part on the patient diary data.

5. The assessment system of claim 1, wherein the data processing system is configured to generate a plurality of asthma status scores and respective confidence ratings comprising at least one individual asthma status score and individual confidence rating and a summary asthma status score and summary confidence rating.

6. The assessment system of claim 1, wherein the environmental data capture system is configured to continuously capture the environmental sensor data and continuously derive the sensor-based environmental data from the environmental sensor data.

7. The assessment system of claim 3, wherein the physiological data capture system is configured to continuously capture physiological sensor data and continuously derive the sensor-based physiological data from the physiological sensor data.

8. The assessment system of claim 1, wherein the data processing system is configured to periodically update the asthma status score and the confidence rating.

9. The assessment system of claim 3, wherein the sensor-based physiological data include at least respiratory data, heart data and saturation of oxygen in arterial blood flow (SpO2) data.

12. The assessment system of claim 1, wherein the sensor-based environmental data comprise relative humidity data.

13. The assessment system of claim 1, wherein the sensor-based environmental data comprise airborne particulate data.

10. An assessment system for assessing the health status of a patient, comprising:

a data processing system;

an environmental data capture system communicatively coupled with the data processing system, wherein the environmental data capture system is configured to capture environmental sensor data and generate sensor-based environmental data in a form usable by the data processing system based at least in part on the environmental sensor data; and

a health data output system communicatively coupled with the data processing system, wherein the data processing system is configured to receive sensor-based environmental data from the data capture system, generate a health status score and a confidence rating for the health status score based at least in part on sensor-based environmental data and output the health status score and the confidence rating to the health data output system, wherein the confidence rating is generated based on at least one of a comparison of an actual number of parameters used to generate the health status score with a predefined number of parameters or a comparison of an actual change rate for the health status score with a predefined change rate, and wherein the health data output system is configured to display the health status score and the confidence rating.

11. The assessment system of claim 10, wherein the data processing system is configured to generate a plurality of health status scores and respective confidence ratings for the health status scores comprising at least one individual asthma status score and individual confidence rating and a summary asthma status score and summary confidence rating.

14. The assessment system of claim 10, wherein the confidence rating is generated based on a comparison of an actual number of parameters used to generate the health status score with a predefined number of parameters and a comparison of an actual change rate for the health status score with a predefined change rate.
