Abstract

The invention provides apparatus and methods for home or other remote delivery of health care that gather subjective and objective measures of patient health and treatment, analyzing them (e.g., correlating them with one another and/or with norms) and reporting them to aid in on-going patient diagnosis and treatment (both on acute and chronic bases), as well as to aid physicians, nurses and other caregivers in decision support, monitoring treatment compliance, facilitating regulatory compliance, billing, and so forth. Thus, for example, in some aspects a health care delivery device comprising a medical treatment apparatus, such as a home hemodialysis or home peritoneal dialysis unit, that is coupled to a processor. The processor generates patient queries in connection with treatments rendered by the dialysis equipment (or other treatment apparatus). The queries are directed, at least in part, to subjective topics, such as the state of the patient'"'"'s mental health and well being, quality of life, degrees of pain, views on success of therapy, and so forth. They are presented on an LCD screen or other output device coupled to the processor to elicit responses on a keyboard or other input device, also coupled to the processor.

Claims

B. an output device that presents information or other output for the patient,

C. an input device that accepts information or other input in response to a query, and

D. a processor that is coupled to the medical treatment apparatus and that generates subjective queries in connection with treatment of the patient thereby, the processor being coupled to the output device for presentation of those subjective queries for the patient and being coupled to the input device for accepting responses to those subjective queries, the processor comprising an analysis module that correlates the patient'"'"'s responses and the biometric readings so as to monitor at least one of the treatment of the patient and operation of the medical treatment apparatus, and

E. wherein the subjective queries include one or more of the patient'"'"'s mental health and well being, quality of life, degrees of pain, and views on success of therapy.

2. The health device of claim 1, wherein the medical treatment apparatus comprises dialysis equipment.

3. The health device of claim 2, wherein the dialysis equipment comprises equipment for any of hemodialysis and peritoneal dialysis.

4. The health device of claim 1, adapted for treatment of the patient in a patient'"'"'s home or other location remote from a dialysis treatment center.

5. The health device of claim 1, comprising communication functionality that transmits messages, input by the patient via the input device, to a remote care provider.

6. The health device of claim 5, the communication functionality accepts messages transmitted from a remote care provider and that presents those messages on the output device.

7. The health device of claim 6, wherein the messages are text messages.

8. A health care delivery system comprising:

A. a digital data processing system,

B. a health care delivery device disposed remotely from the digital data processing system, the health care delivery device being coupled for at least occasional communication with the digital data processing system and including

i. medical treatment apparatus having one or more sensors that sense operating conditions of the medical treatment apparatus as the patient receives medical treatment therefrom,

ii. an output device that presents information or other output for a patient,

iii. an input device that accepts information or other input in response to a query,

iv. a processor that is coupled to the medical treatment apparatus and that generates subjective queries in connection with treatment of the patient thereby, the processor being coupled to the output device for presentation of those subjective queries for the patient and being coupled to the input device for accepting responses to those subjective queries, the processor comprising an analysis module that correlates the patient'"'"'s responses and the operating conditions of the medical treatment apparatus so as to monitor at least one of the treatment of the patient and operation of the medical treatment apparatus, and

v. communication functionality that transmits one or more of the responses to the digital data processing system, and

C. wherein the subjective queries include at least one of the following;

patient'"'"'s mental health and well being, quality of life, degrees of pain, and views on success of therapy.

9. A method of health care delivery comprising:

A. delivering medical treatment to a patient via a medical treatment apparatus,

B. subjectively querying the patient via a health care treatment device associated with the medical treatment apparatus, wherein the step of subjectively querying the patient includes querying the patient about at least one of the following;

patient'"'"'s mental health and well being, quality of life, degrees of pain, and views on success of therapy,

C. accepting responses to those subjective queries,

D. correlating the responses to those subjective queries with operating conditions of the medical treatment apparatus so as to monitor at least one of the treatment of the patient and operation of the medical treatment apparatus.
