The discipline

Perioperative health is a discipline, not a gap between specialties.

It covers the entire surgical window, from the decision to operate through complete recovery: understanding what a patient brings to surgery, preparing what can still be changed, and measuring what happens after.

Everyone owns a moment. No one owns the whole window.

Surgeons own the operation. Anesthesiologists own the physiology of the day. Primary care owns clearance. Nursing owns the floor. Each is accountable for a segment, and each does that work well. No single team has continuous accountability, visibility, and measurement across the whole of it, so the questions that span it go unasked.

The window

The window is longer than the operation.

The perioperative window opens when the decision for surgery is made and closes when recovery is complete. Surgery occupies a single day inside it.

Almost everything that determines how a patient arrives, and how they leave, happens in the weeks on either side.

How the window works

Five stages, and only one of them is the operation.

The window is a sequence, not a date. Each stage produces something the next one needs, and the last one feeds the first.

  1. Understand

    Establish what the patient brings to surgery, and what remains modifiable.

  2. Prepare

    Act on the physiology that can still be improved before the operation.

  3. Care

    Give clinical teams better context at the moment decisions are made.

  4. Recover

    Follow recovery against the patient's own preoperative baseline.

  5. Learn

    Connect preparation and care to recovery, so the next patient begins with better evidence.

Accountability here means end-to-end operational accountability, not professional interest or clinical responsibility.

A discipline, not a replacement

Perioperative medicine and Perioperative Health.

These are not competing terms, and the second does not replace the first.

The established practice

Perioperative medicine

The clinical practice of caring for patients across surgery. Decades of evidence, professional societies, fellowship training, and the clinicians who do this work every day.

The discipline

Perioperative Health

The measurable state of health those patients carry through that same window. It asks what condition the patient is in, what can still be changed, and what actually happened to them afterward.

PERIOME builds the infrastructure through which that health can be understood, prepared, supported, and measured across settings.

What PERIOME builds

A discipline needs infrastructure to be practiced.

Naming a window does not close it. Perioperative health becomes real when a patient can be understood before surgery, prepared against something measurable, followed through recovery, and counted afterward.

PERIOME is building that infrastructure across five layers, from the protocol a patient starts today to the outcomes data that sharpens the next patient's preparation: the Protocol, Morton, the Perioperative Resilience Index, Recovery Intelligence, and the outcomes data layer that connects them. Built with the field, not around it.

The standard

No patient enters surgery unknown.

Make every surgery an opportunity to improve human health. Understand and improve each patient's readiness for surgery, personalize their perioperative care, and measure their recovery afterward.
