FALSE CLINICAL ALARM RATE REDUCTION
First Claim
1. A method for identifying a clinically significant event, comprising:
- setting a value in a virtual call point for each of a clinically significant event duration, a clinical event count period and a clinical event count threshold;
receiving at the virtual call point a plurality of clinical events associated with a patient the duration of at least some of which are detected to be less than the value set for the clinically significant event duration, and maintaining a current count of the clinical events having a duration that is less than the value set for the clinically significant event duration; and
determining that the current count of clinical events having a duration that is less than the value set for the clinically significant event duration is equal to the count threshold value prior to the event count period expiring and determining that the patient is experiencing a clinically significant event.

Abstract
A clinical facility communication network connects a notification system to a plurality of patient monitors and to a plurality of clinician communication devices. Each of the patient monitors operate to detect physiological characteristics associated with a patient and to send event messages to the notification system. The notification system operates to receive the event messages and to determine which of the event messages include information of sufficient clinical significance to warrant generating and sending an alarm to a clinician. The event messages that are determine not to include clinically significant information are ignored.

11. An event notification system, comprising:
-
a virtual call point having a clinical event detector, a clinical event counter, and alarm generation logic; wherein the virtual call point receives a plurality of clinical events associated with a patient, the clinical event detector determining that a least some of the clinical events are not clinically significant and the clinical event counter maintaining a current count of the events that are not clinically significant; and the alarm generation logic detecting that the current count of clinical events that are not clinically significant is equal to a clinical event threshold value prior to a clinical event count period expiring and determining that the patient is experiencing a clinically significant event. - View Dependent Claims (12, 13, 14, 15, 16, 17)
