System, method, and apparatus for automated interactive verification of an alert generated by a patient monitoring device
First Claim
1. A method of verifying an alert generated by an assessment process performed by a patient monitoring system, the method comprising:
- receiving a data set upon which the alert was based;
generating a set of verification questions, based at least in part upon the data set;
posing the verification questions to the patient, and receiving answers in response thereto; and
verifying the alert at least partially on the basis of the answers.

Abstract
A system for verification of an alert generated by an assessment process operating upon patient feedback and physiological data. The system may utilize a categorization for alerts, in order to obtain a rule set corresponding thereto. A question hierarchy may correspond to each rule within the rule set. Each question hierarchy may be posed to the patient to verify the alarm. The verification process may be carried out by a patient monitoring apparatus. The system may also automatically adjust parameter thresholds, and may automatically assess the effectiveness of individual questions in predicting the onset of health care related events.

14. A patient monitoring device comprising:
-
a controller circuit;
an input device coupled to the controller circuit;
an output device coupled to the controller circuit;
a memory device coupled to the controller circuit, wherein the memory device stores a set of instructions, which, when executed, causes the controller circuit to cooperate with the input device and output device to pose inquiries to the patient, receive responses thereto, and to determine whether to generate an alert, based at least upon the responses; and
wherein the memory device further stores a set of instructions, which, when executed, causes the controller circuit to cooperate with the input device and output device to generate a set of verification questions, pose the verification questions to the patient, receive answers in response thereto, and to verify the alert at least partially on the basis of the answers. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of adjusting a threshold that a parameter is tested against to generate an alert in a patient monitoring system, the alert indicating that a given patient may need medical attention, the method comprising:
-
identifying a parameter that has been the basis for the generation of an alert for a span of days, during which a verification process has concluded that the patient has not been in need of medical attention; and
modifying a threshold against which the parameter has been tested to generate the alert, thereby arriving at a new threshold, the modification being based upon the values exhibited by the parameter during at least a portion of the span of days during which the alert was generated. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A method of determining effectiveness of a particular question in predicting onset of a health care related event, the method comprising:
-
determining, for a given patient population and given question, a percentage of the patient populace answering the question in a particular way, on each of a plurality of days preceding a health care related event for each patient in the patient population; and
displaying the percentage of the patient populace answering the question in a particular way, on each of a plurality of days preceding a health care related event. - View Dependent Claims (36, 37, 38, 39)
