Description

1 Method for Determining Care and Prevention Pathways for Clinical Management of Wounds This applicationI is reiated io cu-pending application number 60/i 16,349 (filed January 19, 1999), which is incorporated herein by reference in its entirety.

The present invention relates to methods for consistently designating appropriate treatment protocols for patients, particularly protocols involving wounds or wound prevention.

A number of computer programs have been developed wherein a user, for example a care giver, inputs parameters indicative of a patient assessment into a computer and obtains a care plan as an output. Input parameters can include art recognized assessment parameters, such as those recommended by the National Pressure Ulcer Advisory Board. One example of such a 15 computer program is the Wound and Skin Intelligence System (WSIS) developed by Convatec and Applied Health Sciences. Other similar programs have been developed by Johnson Johnson Medical (a division of Ethicon, Inc.) and Smith Nephew, Ltd.

The effective use of such computer-based methods of deriving care 20 plans often requires simultaneous proximity of the care giver to both the patient and the computer. Care givers without ready access to a patient in close proximity to the programmed computer cannot effectively benefit from such .computer-based approaches. Moreover, even when the programmed computer is available, the practicalities of providing care often makes it awkward to input data prior to rendering a treatment protocol.

Accordingly, there is a need for a method of selecting care plans for patients customized to clinical assessment parameters that does not require immediate interaction with a computer, without compromising the quality of care provided. The present invention proves a method for correlating patient assessment parameters with appropriate treatment protocols. The method provides a visually keyed process to derive a care plan. The process does not require a computer, and when executed with a computer is highly integrated VVwith visual cues Such% a rocess can be embodied in devices that p;rovide WCSaKa u\specesAvw -uu.ooc la bedside tools to assist the care giver to make evidence-based decisions for the care of individuals, such as individuals at risk of forming wounds or individuals who already have wounds, such as a pressure ulcers.

The discussion of the background to the invention herein is inciuded to explain the context of the invention. This is not to be taken as an admission that any of the material referred to was published, known or part of the common general knowledge in Australia as at the priority date of any of the claims.

Throughout the description and claims of the specification the word "comprise" and variations of the word, such as "comprising" and "comprises", is not intended to exclude other additives, components, integers or steps.

Detailed Description of the Invention FIG. 1 relates to an interactive visual scoring sheet 10 that can be used according to a preferred embodiment of the present invention. The interactive visual scoring sheet can take substantially the same visually-cued form on the screen of a computer or personal device assistant (PDA). In electronic form, each scoring choice is separately on a viewing screen represented as in the paper example illustrated in FIG. 1. The interactive visual scoring sheet 10 comprises a first defined scale 11 for classifying or grading a wound or patient according to a first wound factor 12 and a second defined scale 13 for classifying or grading the wound or patient for one or more second wound factors 14. In some embodiments, the second defined scale 13 can include classifying or grading of the wound or patient according to: a defined wound assessment factor, a D-rI InI 1 17A WU UU1/4114 defined wound risk assessment factor, some other classification of a patient's condition, or any combination of such factors. The first defined scale 11 and the second defined scale 13 can be represented by one or more markers 19 corresponding to one or more stages, grades or classifications. Markers 19 and associated criteria 15 can be indicated on the visual scoring sheet 10, for example, by indicia associated with markers 19, including varying colors, numbers, letters, symbols, texture or any combination thereof.

Optional associated criteria is provide a brief indication of the classifying or grading criteria. In some embodiments, the appropriate score for one or more classifying or grading factors can be marked on the interactive visual scoring sheet 10. The criteria can be indicated in whole or in part on the visual scoring sheet 10, or be referenced to criteria found elsewhere. The presence of at least a shorthand reference to the criteria is preferred. The second defined scales 13 can be with respect to one or more second wound factors 14. Second wound factors 14 can, in some embodiments, be selected from any number of factors including but not limited to: exudate amount, necrotic tissue amount, undermining, color of tissue around wound, granulating tissue, peripheral edema, peripheral induration and pain at wound. In some embodiments, second wound factors 14 can include, but are not limited to: sensory perception, moisture, activity, mobility, nutrition and friction shear. In some embodiments, as shown in FIG. 9, first wound factors 12 and second wound factors 14 can be selected from the group consisting of: depth, exudate amount, exudate type, necrotic tissue amount, necrotic tissue type, undermining, surrounding skin color, granulation, peripheral edema, peripheral induration, pain at wound, nutrition, infection, edges, epithelization, functional ability, compliance and healthy margin.

The exemplary wound grading factors selected for FIG. 1 are a subset of the exemplary wound grading factors selected for FIG. 9. The selection of the particular factors of FIG. I as sufficient to predict patient care protocols represents an embodiment of the invention.

In some embodiments, one or more of the markers 19 for the first wound factor 12 or second wound factor 14 pertaining to a wound or patient condition can be connected by connecting indicia 16 such as lines or arrows that identify one or more treatment protocol components 17. One or more treatment protocol components 17 may be correlated to one or more markers 19, for example by connecting indicia 16, and may he written or referred to on the interactive visual scoring sheet n nnA 171A 09-r/ I1 l I1 'A -6- The i!nteractive visual scoring sheet 10 can form, include or be used in reference to a visual decision tree 18. Exemplary decision trees 18 are shown in FIG. 2. The visual decision tree 18 can comprise connecting indicia 16. The visual decision tree 18 can dictate two or more distinct decisions based on one or both of the first or second defined scales 11, 13 to identify a treatment protocol component 17 for the classified or graded factors. In FIG. 2, a first set of markers 19a on a first sliding card 22a are used to indicate values or stages of the first or second defined scales 11, 13. A second set of markers 19b are used on a second sliding card 22b to indicate values or stages of the first or second defined scales 11, 13 in the example illustrated in FIG. 2.

In some embodiments, the first defined scale 11 can grade wounds from nonopen or closed wounds, to wounds of various thicknesses, to wounds that cannot be graded due to obstructions.

To assess a wound, the wound is first visually inspected and the particular wound or patient parameters are determined, for example, according to one or more defined scales for classifying or grading 11, 13. The wound or patient parameters can then be recorded by marking or indicating them on the interactive visual scoring sheet 10, for example by checking or circling appropriate markers 19. Connecting indicia 16 and a visual decision tree 18 can then be used to identify appropriate protocol components 17 corresponding to the indicated markers 19.

In one preferred embodiment of the invention depicted in FIG. 2, a visual decision tree device 20 is provided. A schematic of a visual decision tree device 20 is provided in FIG. 2A. In the nonlimiting example depicted in FIG. 2, the visual decision tree device 20 is a mechanical slide-rule device made up of a first housing 21A with a first view window 28A and a first sliding card 22a. Hingeably attached HINGE to the first housing 21A is second housing 21B into which slides a second sliding card 22b.

The user inputs a value for one or more first 12 or second 14 wound factors according to the markers 19a, 19b for the first or second defined scales 11, 13 displayed on the first or second sliding cards 22a, 22b, for example by adjusting the position of the appropriate sliding card 22a or 22b within the appropriate housing 21A or 21B such that an appropriate marker 19a or 19b corresponding to the desired input value is displayed in view. Selection of the appropriate housing 21A or 21B and slide card 22a or 22b is determined in this example by connecting indicia 16 to the "Classification of Wound" score n the vis-l ornrg sheet 10 of FG 1 WO 00/41714 ~~rm r r~ ~rr rn ~r 1 .WO 00./41714 7 rL IU"UUIUI 14 QUESTION 1 (FIG. 2A) identifies which first or second wound factor 12, 14 is used to identify the appropriate marker 19a. The display of the appropriate marker 19a aligns the appropriate decision or visual decision tree 18a-18d in the view window 28. If present, QUESTION 2 of the displayed visual decision tree identifies a marker 19b for which connecting indicia 16b identify appropriate wound care protocol components 17.

In some instances, such as illustrated decision tree 18c, the decision tree identifies the wound care protocol component 17 from the marker 19a.

Wound care protocol components 17 can be grouped in modules on a wound care protocol sheet 30, as shown in FIG 3. In some embodiments, protocol components 17 for wound care of wound prevention are grouped in alpha-numeric groups or modules 31 that correspond to decision tree 18 outcomes. Based on the decision tree 18 outcomes, one or more protocol components 17 may be followed. The modules 31 can be an alpha-numerically labeled module, can include goals for treatment, multiple alternative therapies and recommended products for treatment.

The schematic of FIG. 2A shows a two part visual decision tree devices comprising a housing 21 and a sliding card 22. The housing can comprise a top layer 23 and a bottom layer 24 made of, for example, heavy paper or plastic, joined along a top edge 25 and a bottom edge 26. A view window 28 is cut into the top layer 23. In some embodiments (not shown in FIG. 2A), the view window can be cut into the top layer or the bottom layer. The sides of the top layer 23 and the bottom layer 24 are left open to allow the sliding card 22 to be inserted and moved within the housing 21. The top layer 23 can have a question QUESTION 1 printed on it, which governs where the operator should slide the sliding card 22 so that the appropriate marker from a first set of markers 19a is indicated in the view window 28. The sliding card 22 is slid within housing 21 to a position with respect to the view window 28 where the QUESTION 1 on the top layer 23 is correctly answered by an appropriate marker 19a. A first set of connecting indicia 16a arrows) points to one or more values for a second set of markers 19b in response to QUESTION 2. The operator selects a value from the second set of markers 19b in response to a second question QUESTION 2 found on the sliding card 22 and performs the protocols (referenced as A, B or C in FIG. 2A at the bottom of the sliding card 22) that are indicated by a second set of arrows 16b.

In a particular example, the grade on first defined scale 11 on the interactive vis!a! scoring sheet 1 of FIG. 1 irentifies whether the slide rule of first housing 21 A or /I I nrf-'T /I IOJIA /ni ^1 VT.J UUI/1iI 8- PC I./uuuS00/012U the slide rule of second housing 21 B shall be used (FIG. Referring to second housing 21B of the visual decision tree device 20 of FIG. 2, the score for alpha second defined scale 13a identifies the position to which the ruler is adjusted. Referring to first and second s!iding cards 22a, 22h of FIG. 2 and FIG. 2C, in the first sliding card 22a, one dialed position on defined scale 13a for first sliding card 22a of FIG. 2C) gives a wound care protocol component 17 depending on the score of beta second defined scale 13c. Another dialed position on defined scale 13a for second sliding card 22b of FIG. 2C) depends on the score of delta second defined scale 13d. Two dialed positions or on defined scale 13a for first sliding card 22a of FIG. 2C) directly indicate wound care protocol components 17. Some dialed positions on the second sliding card depend on gamma second defined scale 13b. Referring to FIG. 1, additional wound care protocol components 17 are identified on the visual scoring sheet by connecting indicia 16 associated with first defined scale 11 and beta, epsilon, zeta, eta and theta wound care protocol components 13B, 13E-13H (FIG. Shown in FIGs.

2B and 2C are particular exemplary first slide and second slide cards 22c, 22d and 22a, 22b, (respectively). Some embodiments, for example as shown in FIG. 5 and FIG. can have a third sliding card 22e and a fourth sliding card 22f which can slide independently of each other to align a first marker 19a or a second marker 19b with a first view window 28a and a second view window 28b, respectively. These exemplary slide cards are shown in FIGs SB and 5C, respectively.

FIG. 2B and FIG. 2C display exemplary sets of first and second sliding cards 22a, 22b which can be used to practice the invention. The sliding cards 22a, 22b include separate visual decision trees 18e-181 that can be aligned with a view window of a housing. Likewise, FIG. 2C displays a set of first and second sliding cards 22a and 22b that include visual decision trees 18m-18t. For example, the first and second sliding cards 22c, 22d of FIG. 2B can be used in the visual decision tree device 20 of FIG. Likewise, the first and second sliding cards 22a, 22b of FIG. 2C can be used in the visual decision tree device 20 of FIG. 2. In FIG. 2B, first and second sliding cards 22c, 22d have markers 19a that correspond to a first defined scale 13a and markers 19b that correspond to one or more second defined scales 13b, 13c, 13d. Similarly, first and second sliding cards 22a, 22b of FIG. 2C have a first set of markers 19a corresponding to a first defined scale 13a, a second defined scale 13b, a third defined scale 13c and a fourth defin d scale 13d, which scales are defined for this example in the interactive 111f' l /A lW* I t~r n II\ ~~1 VVJ UUIII, #I 9 rLk IIU3VVIU I visual scoring sheet 10 of FIG. 1.

The following examples further illustrate the present invention, but of course, should not be construed as in any way limiting its scope.

Example I Wound Treatment One example of a method for assessing the status of a patient and derivation of a care plan, or protocol, for wound treatment is as follows. A front cover of a Wound Care Assessment Record (FIG 7) can be completed and included to identify the patient and care giver and to record dates and details of treatment, or the like. A Wound Assessment Record (Pressure Sore Status Tool), a type of interactive visual scoring sheet (FIG. 1) is completed by circling appropriate assessment scores for each factor (exudate amount, necrotic tissue amount, undermining, surrounding skin color, granulation, peripheral edema, peripheral induration, and pain). Using the interactive visual scoring sheet of FIG. 1, a care giver, upon examining a wound, classifies the wound as Stage 3 according to the first defined scale for classification. The care giver then assigns the following scores to assessing the wound according to their respective second defined scale for grading the wound: Exudate amount 3; Necrotic Tissue Amount 3; Undermining 2; Color of Tissue Around Wound 3; Granulating Tissue 3; Peripheral Edema 1; Peripheral Induration 0; Pain at Wound 4.

I -1 l 1A ll "'IP I! Lk lA rvv~ UU,, II 11 rL IuO.uu ui'' Next, the Chronic Wound Management Pathway Decision Tool, a type of portable mechanical slide-rule visual decision tree device, of FIG. 2 is used as follows: using the Exudate Amount score selected from the interactive visual scoring sheet of FIG. 1. go to the colored side of the slide rule recommended; (ii) from the interactive visual scoring sheet of FIG. 1, identify the score checked for exudate amount and move the slide rule to the score for exudate amount; (iii) follow the arrows, answer all questions and select the appropriate nurse action items; circle the numbers in the Nurse Action Report (Care Plan), a type of modular wound care protocol (FIG. 3).

Accordingly, the care giver having assessed the wound, follows the decision tree provided in FIG. 1 and FIG. 2 to arrive at a care plan from FIG. 3. Following the wound assessment data detailed in the above example, this process is as follows. First, the caregiver notes that the marker for Stage 3 in the Classification of Wound scale has two arrows connected to it: a vertical arrow (which points to "See Red Side of Nurse Action Guide") and a horizontal arrow that passes through the marker pointing from left to right (which points to "Nurse Action The vertical arrow requires the care giver to consult the red side of the decision tool Nurse Action Guide), which corresponds to the top section of FIG. 2. Beginning at "START HERE" in the upper portion of the tool represented in FIG. 2, the care giver slides the card in the housing so that the number determined for Exudate Amount in the wound assessment is showing in the example). Once this is done, an arrow on the sliding card points to Nurse Actions 2 and 2C, which are found in FIG. 3, with accompanying text in Sections 2 and 2A of Table 1.

The care giver then follows the protocols corresponding to Nurse Actions 2 and 2C.

Returning to the interactive visual scoring sheet of FIG. 1, the care giver next visually notes all factors indicated that are intersected by a line with an arrow attached as an endpoint (necrotic tissue amount, surrounding skin color, granulation, peripheral edema, peripheral induration, pain at wound and nutrition). Ifa line attached to the box is checked or circled then the care giver follows through to the end of the arrow where one finds the appropriate nurse action referenced. The care giver then records the nurse action on the modular wound care protocol Nurse Action Report (Care Plan) of FIG. 3) by circling it. Ifa checked or circled box or marker does not have a line attached to it then the care giver is not required to do anything further for that marker. Finally, after circling all numbers on the modular wound care protocol FIG. the care giver follows the care plan and prnoceedc to take action.

WO 00/41714 -12- PCT/USOO/01274 Returning to the visual scoring sheet results in the above example, the horizontal arrow horizontally intersecting marker 3 for classification of wound and pointing to "Nurse Action 5" indicates that the care giver should also perform Nurse Action (which is found in Section 5 of Table 1).

Next, the care giver can examine each marker indicated in the grading scales (from "Exudate Amount" down to "Pain Wound") and look for horizontal arrows passing through a marker. For instance, the marker for indicated for "Necrotic Tissue Amount" has an arrow pointing to "Nurse Action Accordingly, the care giver would then perform the protocol for Nurse Action 3 (found in FIG. 3, with text in Section 3 of Table The results indicated above for "Granulating Tissue" and "Peripheral Edema" both require Nurse Action 4, however such multiple indications for any given Action do not increase the number of times the Action must be performed in this example, Nurse Action 4 is performed once, not twice). Finally, the marker for "Pain Wound" intersects an arrow that points to Nurse Action 6. Thus, in following the example above, the care giver would circle and perform Nurse Actions 2, 2C, 3, 4, and 5 as indicated in FIG. 3 by circles 32.

Example 2 Wound Prevention One example of a method for assessing the status of a patient and derivation of a care plan, or protocol, for wound prevention is as follows. A Patient Risk Assessment Evaluation Sheet (FIG. a type of interactive visual scoring sheet, is completed by a care giver using a variation of the Braden Scale by circling appropriate assessment scores for each risk factor (sensory perception, moisture, activity, mobility, nutrition and friction shear). Second, the Slide Rule Pressure Ulcer Pathway Decision Tool of FIG.

is used as follows: the slide rule is moved to each respective checked score from the Patient Risk Assessment Record (FIG. 4) for each respective risk factor. The arrows downward in the slide rule are followed to select the nurse actions (letters A to X) that correspond with the information contained in the Patient Risk Assessment Record.

Finally, all letters in the a modular wound prevention protocol sheet (also called a Nurse Action Report, FIG. 6) selected from the slide rule are circled. Circled protocols are then tIt ndition WO 00/41714 -21 PCT/US00/01274 followed. Table 3 provides the text of protocols that can be arranged on a single wound prevention protocol sheet, as shown schematically in FIG. 6.

The method of practicing the invention is outlined in the example below. The care giver obtains the Patient Risk Assessment Record (FIG. 4) and the Slide Rule Pressure Ulcer Pathway Decision Tool of FIG. 5, and then examines a patient. The care giver obtains the following assessments: Sensory Perception 3; Moisture 1; Activity 2; Mobility 2; Nutrition 4; Friction Shear 3. After recording this assessment on the Patient Risk Assessment Record (FIG. the care giver follows any arrows in FIG. 4. Specifically, the Moisture grading of 1 points to "See Moisture Chart", the Activity grading of 2 points to "See Activity Chart", the Nurtition grading of 4 has no arrows and the Friction Shear grading of 3 has no arrows.

The care giver the uses the Slide Rule Pressure Ulcer Pathway Decision Tool of FIG. 5, and follows the decision tree for moisture. The first and second sliding cards 22e, 22f of FIG. 5 are displayed in FIG. 5B. Answering all questions, the care giver performs all nurse actions that apply. For instance, if the patient does not suffer urinary or fecal incontinence, but does perspire the care giver would perform Nurse Action F, but not nurse actions A, B, C, D, or E. Further consulting FIG. 5, the care giver slides the sliding card to an Activity rating of 2 and follows the arrows and protocols indicated in the view window (namely Nurse Action K, but not Nurse Action J since the Braden Scale total score is 15 for this patient). The care giver then slides the sliding card until the grade of 3 for nutrition number is indicated in the view window. The care giver then follows protocols indicated in the Nurtition window. For the patient above, given that the patient is only fed orally, Nurse Action P would be performed by the care giver, but not Nurse Actions O or V. The care giver then consults the Friction and Shear section of FIG. 5. Noting that a score of 3 for Friction Shear does not appear with any arrows, no further Nurse Action protocols need be performed. Thus, for the patient of this example, as shown in the Nurse Action Report Sheet (FIG. Nurse Action protocols F, K and P should be performed by the care giver.
