¶ The thesis

The patient leaves the ward.
The monitoring shouldn't.

Sizor is a clinical voice platform that calls patients after they go home, every day or every week, on the cadence their pathway requires. It turns those calls into structured clinical notes, risk scores, and red-flag alerts your team can act on.

Designed for every health system that pays a penalty for readmission, and every patient who falls through the gap when monitoring stops at the door.

SIZOR
Good morning Margaret. I'm calling from the orthopaedic team to see how you're getting on after your knee replacement. How would you rate your pain this morning, on a scale of zero to ten?
PATIENT
It's about a six. Worse than yesterday. And the wound looks a bit red around the edges this morning.
SIZOR
Thank you. I'd like to ask a few more questions about the wound and then I'll flag this for your clinical team to review today...

¶ The gap

Discharge is the moment the system loses sight of the patient, and the moment harm is most likely.

01

Surveys are too thin

PROMs and SMS check-ins capture a single point. They miss the trajectory: whether pain is climbing, whether the wound is changing, whether the patient is taking the right medication.

02

Phone calls don't scale

Trusts know structured follow-up calls work. They also know one nurse can do twenty calls a day, not two hundred. The clinical evidence exists. The labour to deliver it does not.

03

The data dies on arrival

When a follow-up call does happen, the notes go into a free-text box that no analytics layer can use. There is no per-domain score, no trajectory, no escalation logic. The signal is wasted.

¶ The product

A four-step loop that runs from discharge to closure.

I

Enrol

Patient is enrolled at discharge against an OPCS-coded NHS pathway. Sizor maps to NICE guidance and sets the call schedule.

II

Call

Sizor calls the patient on schedule. The voice is calm, conversational, paced for older patients who need a moment to think. Patients can call in too.

III

Score

Each call generates a SOAP note and per-domain trajectory scores: pain, wound, mobility, mood, medications, nutrition.

IV

Escalate

RED flags route to the on-call clinician within seconds. AMBER and GREEN sit in the dashboard for the next ward round.

¶ For the clinical reader

What gets generated, and why your team can trust it.

Per-call SOAP note

Every call produces a SOAP note per clinical domain. Subjective from patient's words, Objective from measurable responses, Assessment as the AI-generated impression, Plan as the suggested next step. Always reviewed by a clinician before action.

Trajectory scoring (0–4)

Each domain is scored on a five-point scale: 0 resolved, 1 expected, 2 monitor, 3 expedite, 4 escalate. Benchmarks are drawn from NICE-aligned recovery curves stored in our pathway database. They are not generated by the AI at runtime.

Risk stratification: RED / AMBER / GREEN

Three flag tiers: auto-detected (locked, e.g. wound infection signs), suggested (editable, AI proposes), and manual (clinician overrides). RED routes to the on-call team within seconds.

SOAP · Wound domain · Day 3 post-op
S: Pt reports increasing pain (6/10) and redness around incision since yesterday. Mild discharge noted on dressing change this morning.
O: Self-reported temp 37.9°C. Wound score 4/4. Pain trajectory rising vs. day 2 baseline.
A: Concern for surgical site infection. Meets RED flag criteria for orthopaedic pathway day 3–5.
P: Escalated to on-call ortho registrar. Recommend same-day clinical review and wound swab.
Generated 09:14 BST · Reviewed by clinician before action
