THE CATENA APPROACH

The Catena Six-Link Framework

Clinical and commercial judgement across the perioperative journey.

We connect six practical questions to the product, buying or investment decision in front of you.

LINK 01

Clinical Need

Is this a problem worth solving?

What we examine
  • Who has the problem, and how serious is it?
  • What happens today without this product?
  • Which decision or outcome should change?

Output: A clinical problem and intended-use brief.

LINK 02

Workflow Fit

Will it work in the real pathway?

What we examine
  • Where does the tool enter the pathway?
  • Who receives its output, and what must they do?
  • Where does it remove work, add work or transfer risk?

Output: A current and proposed workflow map.

LINK 03

Evidence

What supports the claims?

What we examine
  • What is a manufacturer claim and what has been evaluated?
  • Does the evidence match this version, setting and patient group?
  • Which uncertainty would change the decision?

Output: A claims-to-evidence map and evidence priorities.

LINK 04

Commercial Value

Who benefits, buys and pays?

What we examine
  • Who uses, champions, buys and pays for the product?
  • Does the benefit reach the person or organisation bearing the cost?
  • What must be true for the adoption or investment case to hold?

Output: A buyer map, value proposition and business-case assumptions.

LINK 05

Safeguards

What must be controlled?

What we examine
  • What could go wrong, for whom and with what consequence?
  • Who owns oversight, escalation and fallback procedures?
  • Which clinical, technical or regulatory questions require appointed specialists?

Output: A risk and responsibility map with specialist-review actions.

LINK 06

Adoption

How will adoption succeed?

What we examine
  • What pilot or next step would test the important assumptions?
  • What must users learn, and who will support them?
  • What findings would justify progressing, changing or stopping?

Output: An adoption plan with measures, owners and decision checkpoints.
