Abstract

The monitoring device incorporates transducing devices for converting the desired measured parameters into electrical signals capable of being processed by a local computer or microprocessor system. The device interacts with the ambulatory patient and then, via a modem or other electronic communication device, transmits the measured parameters to a computer located at a remote site. At the remote location. the various indicia of the ambulatory patient'"'"'s condition are monitored and analyzed by the medical professional caregiver. To provide the ambulatory patient with an added level of convenience and ease of use, such monitoring device is contained in a single integrated package.

Claims

1. A computer-implemented method of detecting an impending need for rehospitalization of a patient for chronic heart failure in the patient, the method comprising:

receiving, by a remote computer via a communication network, data measured by a cardiac rhythm management device implanted in the patient, the remote computer remote from the patient;

obtaining, by the remote computer via the communication network, a weight measurement of the patient from a home monitoring apparatus;

receiving, by the remote computer via the communication network, answers to a plurality of questions posed to the patient by the home monitoring apparatus, each of the questions representative of a symptom in a plurality of symptoms associated with chronic heart failure, each of the answers assigned a score representing a severity of a symptom in the plurality of symptoms;

calculating, by the remote computer, a total of the scores assigned to the answers;

detecting, by the remote computer, an impending need for rehospitalization of the patient for chronic heart failure based at least in part upon the weight measurement and based at least in part on whether the total exceeds a threshold; and

in response to detecting the impending need for rehospitalization of the patient for chronic heart failure, alerting, by the remote computer, a medical professional caregiver regarding the impending need for rehospitalization of the patient for chronic heart failure.

2. The method of claim 1, wherein the cardiac rhythm management device is a pacemaker.

3. A computer-implemented method of detecting impending need for rehospitalization of a patient for chronic heart failure in the patient, the method comprising:

receiving, at a remote computer via a communication network, data measured by a cardiac rhythm management device implanted in the patient, the remote computer remote from the patient;

receiving, by the remote computer via the communication network, answers to a plurality of questions posed by a home monitoring apparatus, each of the questions representative of a symptom in a plurality of symptoms associated with chronic heart failure, each of the answers assigned to a score representing a severity of a symptom in the plurality of symptoms;

calculating, by the remote computer, a total of the scores assigned to the answers;

detecting, by the remote computer, an impending need for rehospitalization of the patient for chronic heart failure, based at least in part on whether the total exceeds a threshold and based at least in part on the data received from the cardiac rhythm management device; and

in response to detecting the impending need for rehospitalization of the patient for chronic heart failure, alerting, by the remote computer, a medical professional caregiver regarding the impending need for rehospitalization of the patient for chronic heart failure.

4. The method of claim 3, further comprising obtaining, by the remote computer, a weight measurement of the patient.

5. The method of claim 4, wherein the act of detecting impending need for rehospitalization of the patient for chronic heart failure is further based upon the weight measurement.

6. The method of claim 3, wherein the cardiac rhythm management device is a pacemaker.

7. A computer-implemented method of detecting impending need for rehospitalization of a patient for chronic heart failure in the patient, the method comprising:

receiving, with a remote computer external to the patient via a communication network, data measured by a cardiac rhythm management device implanted in the patient, the remote computer remote from the patient;

receiving, by the remote computer via the communication network, a physiological parameter of the patient measured by a home monitoring apparatus;

receiving, with the remote computer, answers to a plurality of questions posed to the patient by the home monitoring apparatus, each of the questions representative of a symptom in a plurality of symptoms associated with chronic heart failure, the each of the answers assigned a score representing a severity of a symptom in the plurality of symptoms;

calculating, by the remote computer, a total of the scores assigned to the answers;

detecting, with the remote computer, an impending need for rehospitalization of the patient for chronic heart failure, based at least in part upon whether the total exceeds a threshold, based at least in part on the data measured by the cardiac rhythm management device, and based at least in part on the physiological parameter; and

in response to detecting the impending need for rehospitalization of the patient for chronic heart failure, alerting, by the remote computer, a medical professional caregiver regarding the impending need for rehospitalization of the patient for chronic heart failure.

8. The method of claim 7, wherein the cardiac rhythm management device is a pacemaker.
