The perioperative health company

Perioperative Health.

The surgical window runs from the decision for surgery through complete recovery. PERIOME builds the clinical infrastructure to prepare patients, measure readiness, inform care, and follow recovery.

Physician-founded. Clinically grounded. Built for institutional adoption.

PERIOME was founded by two board-certified anesthesiologists building the clinical infrastructure for the complete surgical window.

Why PERIOME

The surgical window

From the decision for surgery through complete recovery.

Perioperative health treats preparation, the operation, and recovery as one continuous, measurable system. The operation stays at the center. The physiology a patient brings to it, and the recovery that follows, extend far beyond the operating room.

The system

One connected system across the surgical window.

PERIOME is building the clinical infrastructure to understand the physiology a patient brings to surgery, improve what can still be changed, support the care delivered around the operation, measure recovery, and learn from every outcome.

  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.

Care is delivered by surgeons, anesthesiologists, nurses, and perioperative teams. PERIOME's role is to make the patient better understood, better prepared, and connected throughout.

Defining the discipline

Perioperative health should not be defined by one company or one specialty.

PERIOME convenes the Perioperative Health Council, a cross-disciplinary group of clinicians, researchers and healthcare leaders helping define the language, standards, measurement, evidence and research agenda of perioperative health.

Anesthesiology. Surgery. Nursing. Nutrition and metabolic science. Outcomes research. Health systems. Payers. Technology.

The surgical window touches all of them. Building a discipline that spans it will require all of them.

Where it begins

Start with the part that can still be changed.

PERIOME begins by helping institutions prepare patients more consistently in the days before surgery. That foundation supports readiness measurement, more informed perioperative care, and recovery intelligence across the window.

The Perioperative Health Protocol

One protocol across the surgical window. PREPARE™ runs once daily for the seven days before the operation, building the physiologic reserve surgery is about to spend. READY™ is an ERAS-aligned carbohydrate drink taken on the morning of surgery, on the schedule the surgical team sets. RECOVER™ continues once daily for the seven days after, now oriented toward repair. All fifteen days work across the same six physiologic domains: hydration and electrolytes; metabolic and recovery capacity; neurocognitive resilience; immune and inflammatory resilience; GI integrity and microbiome; micronutrient foundation.

Morton™

The patient-facing experience. Morton establishes where a patient is starting from, organizes the days around the operation, guides preparation, and follows recovery against that starting point. In pilot.

The platform

One window. Three views into it.

The patient prepares with guidance they can follow. The clinical team sees readiness before the operation. The institution learns across cases. The same system, seen from three sides.

Patient

Morton guides preparation and stays connected after discharge.

Clinical team

Readiness and relevant context, visible before the case.

Institution

Recovery followed and outcomes connected across cases.

Perioperative Resilience Index

In development

Readiness expressed as a single measure the care team can act on.

Physician-founded

Built by the physicians at the head of the bed.

PERIOME was founded by two board-certified anesthesiologists who saw the same gap across thousands of surgical cases: medicine had built extraordinary infrastructure for the operation, and very little for understanding and improving the patient across the complete window.

The standard

No patient enters surgery unknown.

Understand and improve each patient's readiness for surgery, support more informed perioperative care, and measure the recovery that follows.
