System and method for evaluating a patient status for use in heart failure assessment

摘要

A system and method for evaluating a patient status from sampled physiometry for use in heart failure assessment is presented. Physiological measures, including at least one of direct measures regularly recorded on a substantially continuous basis by a medical device and measures derived from the direct measures are stored. At least one of those of the physiological measures, which relate to a same type of physiometry, and those of the physiological measures, which relate to a different type of physiometry are sampled. A status is determined for a patient through analysis of those sampled measures assembled from a plurality of recordation points. The sampled measures are evaluated. Trends that are indicated by the patient status, including one of a status quo and a change, which might affect cardiac performance of the patient, are identified. Each trend is compared to worsening heart failure indications to generate a notification of parameter violations.

1. A computer-implemented system for evaluating a patient status for use in heart failure assessment, comprising:
a data module configured to assemble physiological measures which were electronically stored in a memory and directly recorded as data on a substantially continuous basis by medical device for a patient or indirectly derived from the data, wherein the physiological measures comprise measures for the patient and one or more of measures for a peer group of disease specific patients and measures for an overall patient population; a status module configured to sample the physiological measures over a plurality of data assembly points; an evaluation module configured to evaluate and match at each data assembly point the sampled physiological measures to determine a patient status indicator; a diagnosis module configured to determine one of a status quo and a change in cardiac performance of the patient and compare the change in the cardiac performance to worsening heart failure indications; a quality of life module configured to query the patient on a regular basis and collect quality of life measures and to chronicle the quality of life measures with the physiological measures; and a feedback module configured to provide tiered feedback based on the patient status indicator comprising:
a first level module configured to communicate, at a first level, an interpretation of the change in the cardiac performance;a second level module configured to communicate, at a second level, a notification of potential medical concern based on the change in the cardiac performance to the patient;a third level module configured to communicate, at a third level, a notification of potential medical concern based on the change in the cardiac performance to medical personnel; anda fourth level module configured to communicate to a patient medical device of the patient, at a fourth level, a set of reprogramming instructions based on the change in the cardiac performance;wherein the tiered feedback has increasing levels of patient involvement and medical care intervention.
