A focused decision-support concept for haematology referral review

Triagen brings the referral queue, AI-supported triage pathway, clinical evidence, and nurse actions into one workspace. It was designed as a team project for a healthcare customer-experience course.

Challenge

Manual review made inconsistent referrals difficult to scan and compare quickly.

Design direction

Make every recommendation traceable without taking the decision away from the nurse.

My contribution

UX research, workflow framing, interaction design, and high-fidelity prototyping.

The dashboard organizes incoming referrals by pathway, status, and assignment.

Each referral required the same careful detective work

A nurse had to read the letter, find the relevant lab values, decide what mattered, and then assign urgency. The information was available, but it was scattered across the case with no shared interface to guide the review.

One thing we would not compromise onThe AI could organize the evidence. The nurse still made the call.

The interface could suggest urgency and explain why, but accepting or changing that recommendation always stayed with the nurse.

The research pointed to transparency and clinician control

We combined a literature review, stakeholder mapping, low-fidelity prototyping, and feedback from domain experts. Three practical requirements shaped the final direction.

Show the evidence

A summary alone was not enough. Reviewers needed the clinical factors and source information behind a recommendation.

Make authority obvious

Accept and Modify actions needed to be explicit, documented, and clearly owned by the nurse.

Support quick questions

Domain experts wanted a way to query the case without searching through the full referral again.

The workflow became more specific with each round of feedback

The early concepts tested two core moments: finding the cases that need attention and understanding why a case was flagged. Expert feedback then helped us make the nurse's authority more explicit.

Design change

Started with the urgent-case queue

The first concept focused on helping nurses see which referrals needed attention first.

Expert feedback

Experts asked to see the evidence

A summary was not enough. Reviewers needed the clinical factors and source data behind every recommendation.

Design change

Made nurse actions explicit

Accept and Modify became primary actions, making it clear that the nurse—not the AI—owned the decision.

Design change

Added a traceable decision record

Recommendations, changes, notes, and supporting evidence came together in the case history.

ExplanationThe case view evolved to expose urgency factors and preserve an override path.

AI surfaces a suggested pathway. The nurse checks the evidence and decides.

Triagen turns unstructured referral information into a reviewable case workspace. The recommendation is visible, but it never stands alone.

The case workspace keeps the recommendation, evidence, and clinician actions visible together.

Evidence stays connected to the decision

Supporting information is organized around the review task, so nurses can move from recommendation to verification without losing context.

Reflection

The hardest part was not generating a recommendation. It was making that recommendation trustworthy.

Designing Triagen changed how I think about AI in clinical workflows. A useful system cannot simply produce an answer. It must show its reasoning, make uncertainty visible, and leave room for the clinician to disagree.

What I'd test next
  • Run usability testing with triage nurses.
  • Test the AI across diverse patient data to identify gaps and reduce bias.
  • Explore integration with existing hospital systems.
