1. A clinical support system for monitoring one or more patients, said system comprising:
- one or more processors programmed to;
receive patient data for the patients;
for each patient, select one or more monitoring rules from a plurality of monitoring rules based on patient data availability and/or patient context;
determine or predict whether a patient is deteriorating using the selected monitoring rules for the patient; and
,in response to determining the patient is deteriorating, generate an alert, wherein the processors are further programmed to;
calculate a baseline vital signs instability index (VIX) for the patient from VIX values within a past predetermined amount of time;
compare the baseline VIX to the VIX threshold; and
in response to the VIX exceeding the VIX threshold and the baseline VIX exceeding a predetermined fraction of the VIX threshold, determine the patient is deteriorating.

Abstract
A clinical decision support system (16) monitors one or more patients. The system (16) includes one or more processors (84) programmed to receive patient data for the patients. For each patient, one or more monitoring rules are selected from a plurality of monitoring rules based on patient data availability and/or patient context. A determination is made as to whether a patient is deteriorating using the selected monitoring rules for the patient. In response to determining the patient is deteriorating, an alert is generated.

15. A system for assessing the stability of a physiological condition of a patient, said system comprising:
-
one or more processors programmed to; receive patient data for the patient, the patient data including monitoring data and contextual data; calculate a vital signs index (VIX) for the physiological condition from the monitoring data using a predictive model; determine a VIX threshold of instability from the contextual data; determine whether the patient is unstable at least partially by comparing the VIX to the VIX threshold; and
,in response to determining the patient is unstable, generate an alert wherein the processors are further programmed to; calculate a baseline VIX for the patient from VIX values within a past predetermined amount of time; compare the baseline VIX to the VIX threshold; and in response to the VIX exceeding the VIX threshold and the baseline VIX exceeding a predetermined fraction of the VIX threshold, determine the patient is unstable. - View Dependent Claims (18)
