Predictika · Negative pressure wound therapy orders

An AI sales agent's V.A.C. Therapy order, checked before it goes out

An AI sales agent prepares an order for V.A.C. Therapy: a therapy unit, a dressing, canisters, a change schedule, pressure settings and the order pad documents. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of Solventum's published ordering rules and returns a verdict, every reason and the figures it computed.

Scope: V.A.C. Therapy orders (ActiV.A.C., InfoV.A.C., V.A.C.ATS and V.A.C. Freedom units): dressings, canisters, change schedule, pressure settings, contraindications and order pad documents. See everything this validator covers

This validator models V.A.C. Therapy orders across the four therapy units, not just the scenarios shown below.

  • Unit, dressing and canister — each therapy unit has its own canister, dressings come in listed sizes and case sizes, the 1000 mL canister is for acute care, and the White Foam Dressing needs a pressure of at least 125 mmHg.
  • Schedule and quantities — dressings are changed 48 to 72 hours apart and no fewer than 3 times a week (the Peel and Place Dressing can stay up to 7 days), canisters are changed at least weekly, and the order pad allows up to 15 dressings per wound and 10 canisters a month. The schedule is turned into a 30-day need and compared with the quantities ordered and with the need the order states.
  • Contraindications and technique — malignancy in the wound, untreated osteomyelitis, unexplored fistulas, eschar, exposed vessels or organs, acrylic adhesive allergy and silver sensitivity; no foam in tunnels, one wound per unit only through a Y-connector or bridging, and the other connection cautions in the Solventum guidance.
  • Settings and documents — the pressure range by wound type and foam, continuous or intermittent therapy, hours of therapy per day, and the order pad documents: face sheet, history and physical and wound assessment, operative report, offloading, failed therapies, wound age and support surface, pathology report and the original prescriber signature.

Any V.A.C. Therapy order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Solventum does not publish a price list for V.A.C. Therapy, so this validator produces no price build-up or line-item quote), V.A.C. VeraFlo, Prevena and other Solventum wound products, payer coverage criteria and clinical judgment about the patient.

The AI sales agentBuilds the V.A.C. Therapy order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Dressing and canister needs that follow from the change scheduleOnly with care
Each dressing type has its own change interval, so the monthly need needs its own calculation, compared with the quantity ordered and with the order pad limit.		The weekly schedule is turned into a 30-day need on every call and compared with the quantities, the order pad limit and the need the order states.
Contraindications that depend on several choicesOnly with workarounds
Silver sensitivity matters only with the silver dressing and acrylic allergy matters for every drape, so each needs a rule that reads two fields and interacts with the rest.		Every clinical fact and every product choice is in one request, so the conflict is found whichever order the choices arrive in.
Tunnels, multiple wounds and how they are connectedOnly with care
Foam must stay out of tunnels, a second wound needs a Y-connector or bridging, and White Foam is not for bridging; each is a cross-line rule.		The wounds, technique, dressing and tunnel are checked together, including the cautions about grafts, flaps and mixed etiologies.
Pressure ranges that depend on wound type and foamOnly with care
The recommended range is a table by wound type and foam; every wound type and foam pairing is a separate rule to write and maintain.		The range is looked up on every call and the pressure on the order is compared with it.
Documents that depend on the woundOnly with workarounds
Which documents are required changes with the wound type, surgery, stage and location, so the checklist becomes a tangle of conditional rules.		The documents on the order are compared with the wound facts on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1V.A.C. Therapy is contraindicated for patients with malignancy in the wound.
2V.A.C. Therapy is contraindicated for patients with untreated osteomyelitis; therapy must not be initiated on such a wound.
3V.A.C. Therapy is contraindicated for patients with non-enteric and unexplored fistulas.
4V.A.C. Therapy is contraindicated while necrotic tissue with eschar is present; after debridement and complete removal of eschar it may be used.
5Foam dressings must not be placed in direct contact with exposed blood vessels, anastomotic sites, organs or nerves; they must be completely covered and protected first.
6The V.A.C. Drape has an acrylic adhesive coating; with a known allergy or hypersensitivity to acrylic adhesives, do not use the V.A.C. Therapy System.
7Sensitivity to silver is a contraindication for the V.A.C. GranuFoam Silver Dressing, which is on the order.
8Do not place any foam dressing into blind or unexplored tunnels.
9The V.A.C. GranuFoam and GranuFoam Silver Dressings must not be used in tunnels; the V.A.C. White Foam Dressing is the dressing for explored tunnels.
10The dressing size on the order is not one that Solventum lists for that dressing.
11The dressing on the order is listed only in cases of 5, not in cases of 10.
12The canister on the order is not the canister listed for the selected therapy unit.
13The 1,000 mL canister is not intended for use in the home; it is recommended for acute care (hospital) use only.
14Do not use the 1,000 mL canister on patients with a high risk of bleeding or on patients unable to tolerate a large loss of fluid volume.
15The 1,000 mL canister is recommended for acute care (hospital) use only; the order is for a skilled nursing or long-term acute care facility.
16The schedule of 2 dressing changes per week is below the interval Solventum gives for this dressing: no less than 3 times a week for foam dressings, and at least once a week for the Peel and Place dressing with up to 7 days of wear.
174 dressing changes per week need 18 dressings per wound in 30 days, but the V.A.C. Therapy order pad allows up to 15 dressings per wound per month.
18The order has 15 dressings per wound per month, but the change schedule needs 18.
19The order has 18 dressings per wound per month; the order pad allows up to 15.
20The order has 10 dressings per wound per month, but the change schedule needs 13.
21The order states that the schedule needs 15 dressings per wound per month, but the change schedule works out to 13.
22The order has 11 canisters per month; the order pad allows up to 10.
23The order has 3 canisters per month, but the canister must be changed at least once a week, which needs 5 in 30 days.
24The denser V.A.C. White Foam Dressing requires a pressure setting of at least 125 mmHg; the order has 100.
25The pressure setting of 100 mmHg is outside the range of 125 to 175 mmHg that the V.A.C. Therapy Clinical Guidelines recommend for this wound type and foam; the physician must confirm it.
26On a closed surgical incision V.A.C. Therapy is applied continuously for a minimum of two days up to a maximum of seven days; the order has 8 days.
27On a closed surgical incision V.A.C. Therapy is applied continuously for a minimum of two days up to a maximum of seven days; the order has 0 days.
28One therapy unit treats more than one wound only through the Y-connector or bridging technique; the order has 2 wounds and neither.
29Use only V.A.C. GranuFoam Dressings to bridge; the White Foam Dressing is on the order.
30Do not connect infected wounds with non-infected wounds through a Y-connector.
31The order pad requires the face sheet, history and physical, and the most recent wound assessment with every order.
32For a surgical wound the order pad requires the operative report.
33For a stage III or IV pressure injury the order pad requires the age of the wound.
34For a stage III or IV pressure injury on the trunk the order pad requires the use of a group 2 or 3 support surface.
35For a diabetic ulcer the order pad requires offloading and the diabetic management program.
36For a chronic ulcer the order pad requires the therapies that were tried and failed.
37For a cancer-related wound the order pad requires the pathology report.
38The order pad requires the original prescriber signature; stamps and photocopies are prohibited.
39The pressure setting of 150 mmHg is outside the range of 50 to 125 mmHg that the V.A.C. Therapy Clinical Guidelines recommend for this wound type and foam; the physician must confirm it.
40The pressure setting of 100 mmHg differs from the 125 mmHg that the V.A.C. Therapy Clinical Guidelines recommend for this wound type and foam; the physician must confirm it.
41The pressure setting of 50 mmHg is outside the range of 75 to 125 mmHg that the V.A.C. Therapy Clinical Guidelines recommend for this wound type and foam; the physician must confirm it.
42The pressure setting of 125 mmHg is outside the range of 150 to 175 mmHg that the V.A.C. Therapy Clinical Guidelines recommend for this wound type and foam; the physician must confirm it.
43The guidelines recommend continuous therapy for grafts, flaps, dehisced wounds, venous ulcers, closed incisions, the White Foam Dressing and wounds with tunnels; intermittent therapy needs the physician to confirm.
44The guidelines describe closed surgical incisions with V.A.C. GranuFoam Dressings; White Foam on a closed incision needs the physician to confirm.
45The guidelines describe V.A.C. Therapy for full-thickness (stage III and IV) pressure ulcers; the order is for stage 2.
46The guidelines say to keep V.A.C. Therapy on for at least 22 hours in a 24 hour period; the order plans 20 hours.
47Patients with an increased risk of bleeding should be treated and monitored in a care setting the treating physician deems appropriate; the order is for home use.
48Using more than one Y-connector per therapy unit is not recommended; the order has 2.
49It is not recommended to connect grafts or flaps through a Y-connector.
50It is not recommended to connect or bridge wounds of different etiologies on one therapy unit.
51It is not recommended to bridge an infected wound to a non-infected wound.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for V.A.C. Therapy: a therapy unit, a dressing, canisters, a change schedule, pressure settings and the order pad documents. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of Solventum's published ordering rules and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please prepare a V.A.C. Therapy order for Cedar Valley Home Health: one ActiV.A.C. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. 4 dressing changes per week need 18 dressings per wound in 30 days, but the V.A.C. Therapy order pad allows up to 15 dressings per wound per month. The order has 15 dressings per wound per month, but the change schedule needs 18. The order states that the schedule needs 15 dressings per wound per month, but the change schedule works out to 18. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for dressing and canister needs that follow from the change schedule, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the dressing changes per week to 3, the dressings per wound per month to 13, the canisters per month to 6, the failed therapies documented to yes and the stated dressings needed per wound per month to 13.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    14.
