RELIABILITY IN DETERMINATION OF CLINICAL STATE OF A SUBJECT
First Claim
1. A method for ascertaining the clinical state of a subject, the method comprising:
- acquiring at least one physiological signal from a subject;
deriving at least one parameter sequence from at least one desired physiological signal belonging to the at least one physiological signal;
performing an index determination process, thereby to form a diagnostic index based on the at least one parameter sequence, wherein the diagnostic index serves as a measure of the clinical state of the subject and wherein the index determination process includes indicating the diagnostic index to a user;
monitoring at least one input signal, wherein the at least one input signal belongs to a group including the at least one physiological signal and the at least one parameter sequence; and
enhancing, based on the monitoring, the quality of the index determination process.

Abstract
The invention relates to the determination of a diagnostic index indicative of the clinical state, especially nociceptive state, of a subject. In order to improve the quality of the determination process, desired input signals derived from the subject are monitored and the quality of the process is improved based on the monitoring. This is implemented by increasing user awareness of the reliability of the index or by controlling the measurement set-up. Quality information indicative of the reliability of the current index values may be produced based on the input signals. The quality information may then be employed to give an indication of the current reliability of the index and a warning if the reliability of the diagnostic index becomes compromised.
