Abstract
Abstract 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
A method for evaluating a medical condition of a patient, said method comprising: 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, said 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.
Claim 2
Independent Claim
122 words
A method for evaluating a medical condition of a patient, said method comprising: 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, said 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.
Claim 3
Dependent Claim
55 words
The method of claim 1 wherein the step of monitoring comprises monitoring EKG-related characteristics of the patient, wherein the computed primary probability is a probability of a cardiac problem, and wherein the selected diagnostic test is selected from the group consisting of a CK blood test, an ETT, a stress test, and Sestamibi scanning test.
Claim 4
Dependent Claim
64 words
The method of claim 1 further comprising computing a second plurality of conditional probabilities for a second selected diagnostic test, said second conditional probabilities including a first probability of the medical outcome or diagnosis assuming the second selected diagnostic test produces a first outcome and a second probability of the medical outcome or diagnosis assuming the second selected diagnostic test produces a second outcome.
Claim 5
Dependent Claim
82 words
The method of claim 1 further comprising computing a second plurality of conditional probabilities for a second selected diagnostic test, said second plurality of conditional probabilities assuming a particular outcome of the first-mentioned selected diagnostic test, said second conditional probabilities including a first probability of the medical outcome or diagnosis also assuming the second selected diagnostic test produces a first outcome and a second probability of the medical outcome or diagnosis also assuming the second selected diagnostic test produces a second outcome.
Claim 6
Independent Claim
109 words
A method for determining a diagnostic test plan for a patient, said method comprising: monitoring EKG-related characteristics of the patient; based on the measured characteristics, computing a primary probability of a cardiac problem; computing a plurality of conditional probabilities for a selected diagnostic test, said conditional probabilities including a first probability of cardiac problem assuming the selected diagnostic test produces a first outcome and a second probability 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.
Claim 7
Independent Claim
109 words
A method for determining a diagnostic test plan for a patient, said method comprising: monitoring EKG-related characteristics of the patient; based on the measured characteristics, computing a primary probability of a cardiac problem; computing a plurality of conditional probabilities for a selected diagnostic test, said conditional probabilities including a first probability of cardiac problem assuming the selected diagnostic test produces a first outcome and a second probability 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.
Claim 8
Dependent Claim
137 words
A diagnostic apparatus for use with a patient, said apparatus comprising: a monitoring device which during use monitors one or more clinical features of the patient; an output device; and a predictive instrument receiving input from the monitoring device and programmed to: (1) compute therefrom a primary probability of a medical outcome or diagnosis based on the monitored one or more clinical features; (2) compute a plurality of conditional probabilities for a selected diagnostic test, said plurality of conditional probabilities including a first probability of said medical outcome or diagnosis assuming the selected diagnostic test produces a first outcome and a second probability of said medical outcome or diagnosis assuming the selected diagnostic test produces a second outcome; and (3) display the computed primary probability along with the plurality of computed conditional probabilities on the output device.
Claim 9
Dependent Claim
137 words
A diagnostic apparatus for use with a patient, said apparatus comprising: a monitoring device which during use monitors one or more clinical features of the patient; an output device; and a predictive instrument receiving input from the monitoring device and programmed to: (1) compute therefrom a primary probability of a medical outcome or diagnosis based on the monitored one or more clinical features; (2) compute a plurality of conditional probabilities for a selected diagnostic test, said plurality of conditional probabilities including a first probability of said medical outcome or diagnosis assuming the selected diagnostic test produces a first outcome and a second probability of said medical outcome or diagnosis assuming the selected diagnostic test produces a second outcome; and (3) display the computed primary probability along with the plurality of computed conditional probabilities on the output device.
