ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to automated medical diagnosis systems and methods for performing medical diagnostic analysis, and more particularly to such systems and methods that compare patient diagnostic data with predetermined ranges of specific analyte values to provide a disease diagnosis and suggested or contraindicated treatment strategies.
BACKGROUND OF THE INVENTION
Medical research in the second half of the 20th century has produced, and continues to produce, an ever increasing body of knowledge. The complexity and interrelationships of various diseases and the analytes that may be detected in various diagnostic tests for diseases are more than sufficient to tax the capacity of most medical practitioners. To aid medical practitioners in disease diagnosis, computerized expert systems have been developed to collate medical diagnostic data with various diseases to guide physicians in prescribing treatments for their patients. Such prior art medical diagnostic systems do not adequately provide a framework for analyzing the individual patient's diagnostic results to collate such results into a disease analyte pattern. Furthermore, such systems do not address therapeutic and/or contraindicated treatment strategies.
One method, described in PCT Publication Number WO 97/20496, uses the mean value of human experience test results to determine a presence level of a particular indicator for an individual. The use of the mean value does not provide an accurate determination of whether an individual's indicator levels are within a normal range.
SUMMARY OF THE INVENTION
The present invention is a computerized medical diagnostic system and method. The system and method are used analyze and diagnose an individual's analyte levels. An “analyte” is any substance that is quantified or detected by an experimental procedure. In order to perform the analysis and diagnosis, the individual is tested to determine an analyte value for the various analytes found in their body. The test may be performed through various methods, such as through drawing and testing blood, urine or other bodily fluids. The results of the testing provide analyte values for each of the analytes for the individual.
The system of the present invention, as illustrated in
FIG. 1
, includes a computer
100
including at least a central processing unit (CPU)
102
and a storage medium
104
. The storage medium
104
may be, for example, a hard disk drive. The system may also include an input device
106
, for example a keyboard, a mouse or a disk drive and an output device
108
, for example a monitor or a printer. The system includes a first database stored on the storage medium. The first database maintains analyte data information, in the form of analyte values, for a plurality of analytes. The first database includes a plurality of analyte records, wherein each record holds information regarding a particular analyte that was determined from the results of testing a human test group in the same manner the individual was tested to determine the individual's analyte values. Each analyte record includes an analyte low value, an analyte high value and an analyte mode value. The system also includes a second database stored on the storage medium. The second database maintains disease data information, in the form of diseases and associated analytes, for a plurality of diseases. The second database includes a plurality of disease records, wherein each record holds information regarding a particular disease. Each disease record includes a set of analytes associated with a particular disease. Each analyte of the analyte set has an associated analyte level. The analyte level is indicative of the particular disease. Once the databases are stored on the storage medium, an individual's analyte values are then input to the CPU and compared with the first database data to determine a presence levels for each analyte for the individual. The presence level is the relative amount of a particular analyte present in the individual in comparison to the human test group. Thereafter the presence levels are compared with the second database data to determine disease pattern matches associated with the various analyte presence levels.
The analyte presence level for an individual may be affected by many environmental and/or personal factors such as age, sex, race, pregnancy, residence location, previous or current diseases, previous or current drug usage, etc., all of which are factors to be considered in creating an accurate analysis system. The present invention provides a method for correlating such factors with the various test analytes to identify therapeutic and/or contraindicated treatments and drugs.
The present invention provides a method for automated analysis of an individual's analyte values to provide increased accuracy in disease identification.
The present invention also provides increased accuracy in automated disease identification systems by determining analyte presence levels for use in the disease identification analysis.
The present invention further provides an automated medical diagnostic database system wherein an individual's analyte values are automatically categorized as high, normal or low for increased accuracy in disease determination.
The present invention still further provides an automated medical diagnostic database system wherein analyte test results are combined in various panels to provide diagnostic information regarding various bodily conditions and functions.
The present invention also provides an automated medical diagnostic database system wherein diagnostic data in the form of analyte values gathered from testing the individual on a first date and data also in the form of analyte values gathered from subsequently testing the individual on a second date can be compared to provide information regarding the change in the individual's medical health and the effectiveness of an ongoing medical treatment program.
The present invention further provides an automated medical diagnostic database system wherein the known effects of various drugs and other nutritional-biochemical elements can be utilized to better analyze an individuals health status, and to identify therapeutic and/or contraindicated drugs and elements.
The present invention still further provides an automated medical diagnostic database system wherein the effects of personal and/or environmental factors such as age, sex, pregnancy, residence location, prior or current diseases and drug usage, may be utilized to provide a more accurate medical health analysis.
These and other features and advantages of the present invention will become well understood upon reading the following detailed description of the invention.
