Predictika · Ostomy care supply orders

An AI sales agent's ostomy supply order, checked before it goes out

An AI sales agent prepares a supply order for a patient with a stoma: a one-piece or two-piece system, the pouch, the skin barrier size, irrigation accessories and the months of supply. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model, compares the pouch count the agent states with the one it computes, and returns a verdict, every reason and the figures it computed. The patients in the scenarios are fictional.

Scope: Convatec Natura+ and Esteem synergy two-piece systems, Esteem+, Esteem+ Flex Convex and ActiveLife one-piece systems, and Visi-Flow irrigation accessories. See everything this validator covers

This validator models ostomy supply orders built from Convatec's public product names, not just the scenarios shown below.

  • Systems and pouches — Natura+ and Esteem synergy (two-piece); Esteem+, Esteem+ Flex Convex and ActiveLife (one-piece); drainable, closed-end and urostomy pouches and the ActiveLife stoma cap, against the stoma type; convex versions only where Convatec lists them.
  • Fit — the flange or barrier size against the stoma size, the 38, 45, 57 and 70 mm flange sizes of the two-piece systems, and a nurse review when the opening is much wider than the stoma.
  • Supply — pouches and skin barriers ordered in boxes of 10 against the monthly need and the months of supply, and the pouch count the order states.
  • Accessories — the Visi-Flow Irrigation Adapter Faceplate (two-piece only) and Visi-Flow irrigation (colostomy only).

Any ostomy supply order that touches these products and rules is in scope, not only the scenarios pictured here. Product names and the pouch and convex versions each system lists are from Convatec's public product pages. The pairing of pouches with stoma types, the stoma fit allowance, the box size, the barrier-per-pouch ratio and the supply and review limits are modeled from comparable ostomy products and are not Convatec-published rules; this is not clinical advice. Not covered: prices (this validator produces no price build-up or line-item quote), wound care and other Convatec lines, and other ostomy products.

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
Stated pouch count that must equal the boxes orderedOnly with care
A stated figure is a free-entry field; a rule can compare it with a computed total, but someone has to write and maintain that comparison.		The stated count travels with the order and is compared with the computed total on every call.
A convex version that only some pouches haveOnly with workarounds
The system, the pouch and the barrier shape are separate fields, and the allowed combinations are an irregular list.		System, pouch and shape are in one request and checked together.
A pouch type that depends on the stoma typeOnly with workarounds
The patient's stoma is on one line and the pouch on another, so it needs a cross-line rule that interacts with the others.		Stoma and pouch are checked together, with the reason stated.
Boxes that must cover the months of supply, with barriers at one per three pouchesOnly with care
A calculation across two quantity lines and a period; it works, but nobody ties it to the quote.		Pouch and barrier counts are computed and compared with the need in the same call.
Accessories that fit only some systems or stoma typesOnly with workarounds
Each accessory has its own condition on a different line of the order.		Every accessory is in one request, so the conflict is found whichever order the choices arrive in.
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 order; approval findings need a person to sign off; everything else is computed.

    
1A urostomy pouch is used for a urostomy and only for a urostomy; the pouch and the stoma type on the order do not match.
2An ileostomy has liquid output and needs a drainable pouch; the order has a closed-end pouch.
3The stoma cap is an ActiveLife one-piece product and is used for a colostomy only.
4The Esteem+ Flex Convex pouches are convex products; a flat barrier is not offered with them.
5This system offers a convex version only as a urostomy pouch (ActiveLife) or as a drainable or urostomy pouch (Esteem+); the order has a convex barrier with another pouch.
6The two-piece systems are ordered in flange sizes of 38, 45, 57 and 70 mm; the order has 50 mm.
7A barrier size of 12 mm is outside the 13 to 70 mm range of this model.
8The 45 mm flange leaves 2 mm around a 43 mm stoma; at least 3 mm is needed.
9The 45 mm flange leaves 11 mm around the stoma; a stoma care nurse should confirm the size.
10The order has 20 pouches, but the patient needs 30 for the supply period.
11The order has 10 skin barriers; one barrier serves three pouch changes and 40 changes are needed.
12A one-piece system has the skin barrier built into the pouch; the order also has separate skin barriers.
13The Visi-Flow Irrigation Adapter Faceplate is a two-piece accessory; the order has a one-piece system.
14Visi-Flow irrigation is used for a colostomy only; the stoma type on the order is different.
15A supply period of 4 months needs a review of the stoma and the plan of care.
16A supply period runs 1 to 12 months in this model; the order has 13 months.
17The order states 40 pouches in total, but the boxes on it give 30.

The recorded result of the validator for each scenario on this page: the request the AI agent sent, the verdict, and every finding, in the order they appear above.

    
1. Three-month supply, ileostomy: Three months of Esteem+ convex closed-end pouches for an ileostomy, with irrigation and a faceplate

    
The agent's request. Please prepare an order for 3 months of Esteem+ convex one-piece closed-end pouches for a patient with an ileostomy and a 40 mm stoma, 60 pouches a month, with a 45 mm barrier, 10 boxes of pouches and 2 boxes of skin barriers, with the Visi-Flow Irrigation Adapter Faceplate and Visi-Flow irrigation. The order states 180 pouches in total. It is ready to send.

    
Verdict: Blocked.

    
    
      
  • Closed-end pouch for an ileostomy. An ileostomy has liquid output and needs a drainable pouch; the order has a closed-end pouch.
    • 
      
  • Convex not offered for this pouch. This system offers a convex version only as a urostomy pouch (ActiveLife) or as a drainable or urostomy pouch (Esteem+); the order has a convex barrier with another pouch.
    • 
      
  • Pouches do not cover the supply period. The order has 100 pouches, but the patient needs 180 for the supply period.
    • 
      
  • Separate barriers with a one-piece system. A one-piece system has the skin barrier built into the pouch; the order also has separate skin barriers.
    • 
      
  • Irrigation faceplate on a one-piece system. The Visi-Flow Irrigation Adapter Faceplate is a two-piece accessory; the order has a one-piece system.
    • 
      
  • Irrigation for a stoma that cannot be irrigated. Visi-Flow irrigation is used for a colostomy only; the stoma type on the order is different.
    • 
      
  • Stated pouches differ from the order. The order states 180 pouches in total, but the boxes on it give 100.
    • 
    

    
2. Three-month supply, ileostomy: The agent resubmits after fixing the errors

    
The agent's request. Please prepare an order for 3 months of Esteem synergy convex two-piece drainable pouches for a patient with an ileostomy and a 40 mm stoma, 60 pouches a month, with a 57 mm flange, 18 boxes of pouches and 6 boxes of skin barriers, with the Visi-Flow Irrigation Adapter Faceplate. The order states 180 pouches in total. It is ready to send.

    
Verdict: Needs approval.

    
    
      
  • Wide gap around the stoma. The 57 mm flange leaves 17 mm around the stoma; a stoma care nurse should confirm the size.
    • 
      
  • Order summary. 180 pouches and 60 skin barriers ordered for 3 months; the patient needs 180 pouches.
    •

4. Stoma caps: ActiveLife stoma caps for an ileostomy with a 38 mm barrier

    
The agent's request. Please prepare an order for 1 month of ActiveLife one-piece stoma caps for a patient with an ileostomy and a 41 mm stoma, 30 pouches a month, with a 38 mm barrier, 3 boxes of pouches. The order states 30 pouches in total. It is ready to send.

    
Verdict: Blocked.

    
    
      
  • Stoma cap outside ActiveLife or colostomy. The stoma cap is an ActiveLife one-piece product and is used for a colostomy only.
    • 
      
  • Flange too small for the stoma. The 38 mm flange is 3 mm smaller than the 41 mm stoma; at least 3 mm of room around the stoma is needed.
    • 
    

    
5. Stoma caps: The agent resubmits after fixing the errors

    
The agent's request. Please prepare an order for 1 month of ActiveLife one-piece drainable pouches for a patient with an ileostomy and a 41 mm stoma, 30 pouches a month, with a 45 mm barrier, 3 boxes of pouches. The order states 30 pouches in total. It is ready to send.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a supply order for a patient with a stoma: a one-piece or two-piece system, the pouch, the skin barrier size, and more. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model, compares the pouch count the agent states with the one it computes, and returns a verdict, every reason and the figures it computed. The patients in the scenarios are fictional.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please prepare an order for 3 months of Esteem+ convex one-piece closed-end pouches for a patient. The order states 180 pouches in total. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with seven findings, all in one answer. An ileostomy has liquid output and needs a drainable pouch; the order has a closed-end pouch. This system offers a convex version only as a urostomy pouch (ActiveLife) or as a drainable or urostomy pouch (Esteem+); the order has a convex barrier with another pouch. The order has 100 pouches, but the patient needs 180 for the supply period. The other four are on screen.
    6. 
      
  6. The validator returned seven 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 order are checked against each other.
    7. 
      
  7. What this shows: for boxes that must cover the months of supply, with barriers at one per three pouches, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the system to esteem synergy two-piece, the pouch to drainable pouche, the flange or barrier size to 57 mm and the boxes of pouches to 18. Two more changes are on screen.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The seven blocking findings are cleared; one approval remains for a person: wide gap around the stoma.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the flange or barrier size to 45 mm.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the order.
    18. 
      
  18. Seven problems caught in one call, fixed in two passes, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
