Abstract

An automated medical diagnostic system and method are disclosed. In an embodiment of the system and method, a matrix of cells is displayed via a graphical user interface on a computing device, each cell being representative of a patient health item (PHI) associated with a particular disease. A PHI is entered on the display in one of the cells and a differential diagnosis is updated based on the input PHI. The updated differential diagnosis is then displayed to a user. The system includes multiple diagnostic functions that use the matrix for input and output, wherein the diagnostic functions are selectively executed according to each newly input PHI so as to result in the differential diagnosis. In certain embodiments, the input PHIs are stored in a patient medical record. The computing device can operate independently or in a connection with a system server.

Claims

1. An automated medical diagnostic system, comprising:

a graphical user interface (GUI) displaying a matrix of cells, each cell being representative of a patient health item (PHI) associated with a particular disease, wherein a first axis of the matrix of cells is organized according to standard anatomic systems and a second axis of the matrix of cells is organized according to different parts of a medical workup; and

a processor programmed to execute a plurality of diagnostic functions, said processor uses the matrix for input from a user of the GUI, wherein the processor selectively executes the diagnostic functions according to each newly input PHI so as to result in and display a list of possible diagnoses and updated differential diagnosis,

wherein;

one or more cells is representative of a nested matrix of selectable cells, each cell of the nested matrix being representative of at least one disease associated with a subset of the cause of disease acting on an anatomic subsystem of the body;

when the processor determines that a newly input PHI renders a particular disease impossible to reach a diagnostically significant threshold, the processor removes the particular disease from further consideration in the differential diagnosis and disables the particular disease from suggesting additional PHIs; and

when the processor determines that a diagnostically significant threshold is reached, the processor segregates any diseases that do not meet or exceed such threshold from suggesting additional PHIs.

2. The system defined in claim 1, wherein the particular disease comprises at least one of one of an abnormality, affliction, ailment, anomaly, disorder, illness, indisposition, infirmity, malady, problem and sickness of a patent.

3. The system defined in claim 1, wherein at least one of the plurality of diagnostic functions comprises computer usable code configured to perform a meta analysis of the input PHIs.

4. The system defined in claim 1, wherein at least one of the plurality of diagnostic functions comprises computer usable code configured to request a user of the system to consult the system at a later time.

5. The system defined in claim 1, wherein a PHI comprises at least one of one of a sign, symptom, complaint, presentation, manifestation, finding, laboratory test result, home test result, and an interpretation of an imaging study.

6. The system defined in claim 1, wherein the GUI is configured for use by a trained health professional.

7. The system defined in claim 1, wherein the processor is configured to provide a differential diagnosis to at least one of veterinarians, chiropractors, dentists, optometrists, and holistic health providers.

8. The system defined in claim 1, wherein the differential diagnosis is a single disease.

9. The system defined in claim 1, wherein the system comprises a handheld computing device, a personal digital assistant (PDA) or a PDA-like computing device.

10. The system defined in claim 1, wherein questions are presented directly to the patient.

11. The system defined in claim 1, in which the processor is configured to automatically recognize potentially dangerous situations and a metric of the potential danger to the patient is graphically displayed by the GUI.

12. The system defined in claim 1, wherein the processor is configured to automatically recognize potentially dangerous situations and a metric of the potential danger to the care giver is graphically displayed by the GUI.

13. An automated medical diagnostic system, comprising:

a graphical user interface (GUI) displaying a matrix of selectable cells, each cell being representative of at least one disease associated with a cause of disease acting on an anatomic system of the body, wherein a first axis of the matrix of cells is organized according to standard anatomic systems and a second axis of the matrix of cells is organized according to different parts of a medical workup; and

a processor executing diagnostic software, wherein, in response to selection of a cell via the GUI, the diagnostic software generates a list of possible diagnoses and updates a differential diagnosis associated with the selected cell,

wherein;

one or more selectable cells is representative of a nested matrix of selectable cells, each cell of the nested matrix being representative of at least one disease associated with a subset of the cause of disease acting on an anatomic subsystem of the body;

the diagnostic software is configured to determine that a newly input PHI renders a particular disease impossible to reach a diagnostically significant threshold and remove the particular disease from further consideration in the differential diagnosis; and

the diagnostic software is configured to determine that a diagnostically significant threshold is reached and segregate any diseases that do not meet or exceed such threshold from populating selectable cells in the nested matrix.

14. The system defined in claim 13, wherein selecting a cell identifies a particular cause of disease and a particular anatomic system of the body and can cause a nested matrix of selectable cells to be displayed, each cell of the nested matrix being representative of at least one disease associated with a subset of the particular cause of disease and a subset of the particular anatomic system of the body.

15. The system defined in claim 13, wherein the anatomic systems of the body include at least one of cardiovascular system, respiratory system, nervous system, digestive system, reproductive system, hematopoietic, ophthalmologic, ear, nose and throat, musculoskeletal, dermatologic, endocrine, whole body, and product of conception.

16. The system defined in claim 13, wherein the causes of disease include at least one of trauma, infection or infestation, allergic or immune, poisoning, environmental, vascular, mental, genetics, nutritional/metabolic/endocrine, oncology, and whole body.

17. The system defined in claim 13, wherein an entire column or entire row of the matrix is selectable.

18. The system defined in claim 13, wherein the diseases represented by the selected cells are unfiltered by previously established patient health items (PHIs).

19. The system defined in claim 13, wherein a single disease is represented by a plurality of cells.

20. The system defined in claim 13, wherein a topographic area of a patient'"'"'s complaint(s) is indicated on an avatar displayed by the GUI which then causes different diagnostic weights to be added to various diseases.

21. The system defined in claim 20, wherein the topographic area of the avatar is indicated by a patient.

22. The system defined in claim 20, wherein the avatar is used to register the chief complaint of a patient.
