Abstract

The present invention relates to methods for consistently designating appropriate treatment protocols for patients, particularly protocols involving wounds or wound prevention. Specifically, the invention relates to methods wherein a patient condition such as a wound is assessed against defined scales for classifying and grading, which assessment is used in a visual decision tree device to identify one or more components of a treatment protocol.

Claims

1. A method of identifying a wound care protocol for a given wound or wound prevention protocol appropriate for a given patient comprising:

classifying the wound or patient against a defined scale for a first wound factor, which is a defined wound assessment factor or defined wound risk assessment factor to obtain a wound classification;

grading the wound or patient against defined scales for one or more second wound factors, which are wound assessment factors or wound risk assessment factors; and

operating a mechanical visual decision tree device to show a decision or visual decision tree corresponding to the wound classification or to a scale for a wound assessment factor, wherein the visual decision tree device identifies at least one component of a treatment protocol for the graded wound factors.

2. The method of claim 1, wherein at least one visual decision tree indicates two or more distinct decisions based on the grade of one or more second wound factors.

3. A method of claim 1 of identifying a wound care protocol appropriate for a given wound comprising:

classifying the wound against a defined wound classification scheme;

grading the wound against defined scales for one or more second wound assessment factors; and

operating visual decision tree device to show a decision or visual decision tree corresponding to the wound classification or to a grade for a wound assessment factor, wherein at least one visual decision tree produced by the device dictates two or more distinct decisions based on the grade of one or more second wound assessment factors, and wherein the visual decision device identifies a treatment protocol for the wound classification and grades of the second wound assessment factors.

4. The method of claim 3, wherein one of the two visual decision tree devices is selected based on wound classification, and the selected visual decision tree device is operated to show a decision or decision tree corresponding to a grade for exudate amount.

5. The method of claim 3, wherein the wound classification scheme grades wounds from non-open or closed wounds, to wounds of various thicknesses, to wounds that cannot be graded due to obstructions.

6. The method of claim 1, further comprising:

providing an interactive visual scoring sheet on which markers for the available scores for two or more wound factors are displayed; and

marking the appropriate score for the two or more wound factors on the interactive visual scoring sheet,

wherein the interactive visual scoring sheet contains a marker associated with one or more of the scores identifying an addition to the treatment protocol.

7. A visual decision tree device for identifying a wound care protocol for a given wound or wound prevention protocol appropriate for a given patient comprising:

a mechanical device for identifying and displaying one of at least two decisions or visual decision trees based on one or more inputted wound factors according to a defined scale,

wherein the visual decision tree device identifies at least one component of a treatment protocol for the graded wound factors;

and wherein the mechanical device comprises at least one card on which the decisions or visual decision trees and values for a wound factor are printed; and

a sleeve in which the card slides having at least two openings, the first opening alignable separately with separate wound factor values, and the second opening alignable with the distinct decisions on visual decision trees depending on the alignment with the first openings.

8. The visual decision tree device of claim 7 wherein the card comprises markers corresponding to a defined scale for classifying the wound or patient.

9. The visual decision tree device of claim 7 wherein one or more cards shows a visual decision tree and wherein the housing comprises a view window through which one or more visual decision trees corresponding to the wound classification can be viewed.

10. A method of identifying a wound prevention protocol appropriate for a given patient comprising:

classifying the patient against a defined scale for a first wound risk assessment factor to obtain a wound classification;

grading the patient against defined scales for one or more second wound risk assessment factors; and

operating a mechanical visual decision tree device to show a decision or visual decision tree corresponding to a scale for a wound risk assessment factor, wherein the visual decision tree device identifies at least one component of a treatment protocol for the graded wound risk assessment factors.
