PreOp Screen
Before surgery, every patient's health history has to be checked. We turned phone calls and paperwork into a 3-minute form on the patient's phone, and a report the doctor signs in one click.
for the patient to fill in the form on their phone. No app, no password.
where the doctor sees every patient, the riskiest at the top.
to turn a reviewed patient into the report the surgeon receives.
reports sent without the doctor's signature. Ever.
Getting a patient readyfor surgery took too many phone calls.
The practice checks patients before surgery for surgery centres, remotely. Before anyone goes under anesthesia, the doctor has to know their history, their medicines and anything that could make the operation unsafe.
- Staff phone patients one by one to collect their history
- Forms come back half filled in
- One missed medicine can cancel a surgery on the day
- Reports put together by hand
- The patient gets a link and fills it in on their phone
- The form will not move on until the key questions are answered
- Risky answers are flagged the moment they arrive
- The report is ready in one click, and the doctor signs it
Five steps.One signature.
Tap any step to see what happens there. The doctor stands between the system and the surgeon, so nothing reaches the operating room without a person checking it.
System checks the answers. The moment the form arrives, it is compared with the practice's own checklist. Anything risky is flagged, and the patient is placed high, medium or low risk.
A phone for the patient. A worklist for the doctor.

Simple questions
Warnings with reasons
Report, ready to sign
“Not sure” isnot the same as “No”.
Patients often do not know if a pill they take counts as a blood thinner. Most forms force a Yes or No, and an unsure patient picks No.
So every yes-or-no question has a third answer. “Not sure” becomes a question for the team to follow up, never a quiet No.
Do you take a blood thinner?
Many systems would quietly treat this as a No. Here it stays a question, and the team checks with the patient before surgery.
Riskiest patientsat the top.
Every warning says why it was raised and which answer caused it. When a case needs a video visit before surgery, the visit is booked automatically.

Drafts the doctor's notes. Optional, and switched on only by the practice.
The doctor's own rules, built in. They work even when AI is switched off.

AI helps word the notes, and they are checked against the patient's answers before the doctor sees them.
Turn AI off and the same 5 warnings appear. Safety never depends on the AI.
234 checks built in.0 switched on without her.
The doctor gave us her medical guidelines: 234 checks, written in plain English. We loaded every one, and prepared 63 so the computer can run them.
But none of them screens a real patient until she has read it and approved it. The approve button simply refuses a check she has not reviewed.
One page.One signature.
One click turns a reviewed patient into the clearance report the practice already used: cleared, cleared with conditions, or on hold. Print it, save it as a PDF, or email it to the surgeon.
It stays a draft until the doctor signs. After that it is locked, so the surgeon always sees exactly what was signed.
Practice details hidden for privacy. All patients shown are fictional demo data.
A mistake we caughtbefore any patient did.
In testing, the doctor's notes ended every patient the same way: no reason not to proceed. Even for a patient on hold with four warnings on the same page.
The notes and the report go to the surgeon together, so they must never disagree. Now an automatic test compares every note with the report before anything can be sent.

Common questions
What is PreOp Screen?
A pre-surgery screening platform for an anesthesia practice. Patients fill in a short form on their phone, answers are checked against the doctor's own rules, and the doctor signs a clearance report for the surgeon.
How do patients fill it in?
They get a link by text or email and complete 18 short steps in about three minutes. No app and no password.
Does the AI decide who is risky?
No. Risk checks are the practice's own rules. AI optionally helps word the doctor's notes, and switching it off gives the same warnings.
Can a report be sent without the doctor?
No. Reports stay drafts until the doctor signs, and signed reports are locked.
