WoundWatch

AI-powered post-operative care

Catching surgical infections before they reach hospital

Most surgical site infections develop at home, after discharge — exactly when monitoring stops. WoundWatch lets patients check their wound daily in under three minutes, and uses explainable AI to flag concerning changes to the clinical team early.

The problem

A silent gap in post-operative care

A patient goes home two days after surgery with a leaflet and a clinic review weeks away. If the wound starts to deteriorate in between, no one sees it until symptoms are severe — often an A&E visit, readmission, or reoperation.

Most surgical site infections occur after discharge

This is the point at which surveillance is weakest and the window for simple, early intervention is most often missed. Community studies suggest post-discharge infections account for a substantial, systematically undercounted share of the total SSI burden.

Our solution

One platform connecting patients, AI and clinicians

WoundWatch links a patient-friendly app, explainable AI, and a clinician dashboard — with a clinician always in the loop. No autonomous decisions.

Patient app

Patient-first experience

A guided daily check-in that takes less time than making a cup of tea.

  • Step-by-step guided wound photography from home
  • Quick symptom checks on pain and temperature
  • Complete in under three minutes a day
Explainable AI

Explainable AI intelligence

Analyses images and symptoms, then explains what changed and why it matters clinically.

  • Wound image and symptom analysis
  • Risk scoring with clear, reviewable reasoning
  • Clinician-in-the-loop — every alert is triaged by a person
Clinician dashboard

Clinician workflow

Brings the right patients to the team's attention, with the context to act fast.

  • Risk-stratified patient list, prioritised by infection risk
  • Photo timeline showing wound progression over time
  • Designed to integrate with existing NHS systems

How it works

Intelligent care, simple workflow

From a daily photo at home to a timely intervention, in four steps.

Step 1

Patient checks in

Uploads wound photos and symptoms from home in under three minutes a day.

Step 2

AI detection

The AI identifies concerning changes and calculates an infection-risk score.

Step 3

Clinician review

Alerts are triaged by the care team for clinical oversight and decision-making.

Step 4

Early intervention

Timely treatment prevents readmission, reoperation and complications.

Health economics

A cost-effectiveness case, built to NHS standards

An independent cost-utility analysis modelled WoundWatch against standard care for adults undergoing elective large bowel surgery, from the NHS England & PSS perspective and consistent with the NICE reference case.

Base case result
Dominant
Lower cost and marginally higher QALYs than standard care over a one-year horizon
−£33
Modelled cost saving per patient (£511.92 vs £545.01)
52 wk
Markov model horizon with NICE-standard 3.5% discounting
RCT next
Trial validation is the agreed next milestone

Confident, but honest about the stage. The model shows that if WoundWatch achieves the assumed reductions in infection incidence and time-to-treatment, it is cost-effective — and likely cost-saving — for the NHS.

Those effectiveness assumptions are drawn from analogous remote-monitoring evidence rather than a WoundWatch-specific trial. We present this as a technology with plausible cost-effectiveness that warrants empirical validation, not one already proven. A randomised controlled trial with an embedded economic evaluation is the planned next step.

Why WoundWatch

Clinically grounded, NHS-ready, and moving

Clinical champions secured

Backed by consultant surgeons at University Hospitals Sussex and University Hospitals Coventry & Warwickshire.

Health economics complete

A full cost-utility analysis is done, with a dominant base case and RCT validation as the next step.

NHS pilot discussions underway

In active conversation with NHS Trusts about pilot deployment of the platform.
