A method for evaluating a medical condition of a patient including the steps of monitoring one or more clinical features of a patient; based on the monitored features, computing a primary probability of a medical outcome or diagnosis; computing a plurality of conditional probabilities for a selected diagnostic test, the computed conditional probabilities including a first probability of the medical outcome or diagnosis assuming the selected diagnostic test produces a first outcome and a second probability of the medical outcome or diagnosis assuming the selected diagnostic test produces a second outcome; and displaying the computed primary probability as well as the plurality of computed conditional probabilities to a user as an aid to determining whether to administer the selected diagnostic test to the patient.

Diagnostic tool using a predictive instrument

A method for continuously monitoring the medical condition of a patient, the method including the steps of continuously monitoring one or more clinical features of the patient; periodically computing a probability of a medical outcome or diagnosis based upon the continuously monitored one or more clinical features; from the periodically computed probability of a medical outcome or diagnosis, computing a change-of-condition measure; periodically comparing the change-in-condition measure to a threshold value; and if any computed change-in-condition measure exceeds the threshold value, generating an alarm notification.

Continuous monitoring using a predictive instrument

An instrument for continuously monitoring the condition of a patient who has a cardiovascular disease, the instrument including an electrocardiograph; a waveform analyzer which analyzes a current segment of an ECG waveform; a computer receiving output from the waveform analyzer; and a control module. The computer is programmed to complete a monitoring cycle in which the computer uses the output from the waveform analyzer to compute a probability of a life threatening cardiac condition based upon the current segment of the patient's ECG waveform. The control module causes the computer to periodically repeat the monitoring cycle and for each repetition of said monitoring cycle to compute a change-of-condition measure, wherein the change-of-condition measure is calculated by subtracting a computed probability for a previous monitoring cycle from the computed probability for the current monitoring cycle. The computer is also programmed to compare during each monitoring cycle the computed change-of-condition measure for that monitoring cycle to a threshold value and if in excess of the threshold value to generate an alarm notification.
