An independent exploration of a shared frontier

Medicine beyond
conventional reach.

When distance, environment, time and limited support change what care demands.

01 / The field

Different environments.
One enduring question.

How do we deliver and sustain meaningful care when the support we depend on is out of reach?

Frontier medicine brings that question into focus across remote landscapes, deployed settings, disrupted infrastructure and human spaceflight. The same challenge can arise close to a hospital when access, expertise or continuity breaks down. It connects prevention, diagnosis, intervention and care over time.

Our working definition

The practice and advancement of medicine where distance, environment, limited resources or gaps in access, expertise and continuity challenge conventional care.

Here, “frontier medicine” is a proposed umbrella for shared problems across established disciplines. It is an invitation to connect their knowledge, not a claim of a newly recognized medical specialty.

A shared framework

Six domains.
Many points of connection.

Imaging &
diagnostics

Acquiring, interpreting and sharing diagnostic information when equipment, power, connectivity or specialist expertise are limited.

Imaging in extreme environments

Interventional &
procedural medicine

Image-guided interventions, other procedures and surgery adapted to the setting, with the anesthesia, perioperative support and recovery needed to make care possible.

Interventions in space

Occupational &
environmental medicine

The relationship between people, their work and their surroundings. Exposure, prevention and the conditions that make safe work and care possible.

Work & health

AI & data
in medicine

Tools that help people acquire information, follow change over time, interpret uncertainty and coordinate decisions. Their value depends on evidence, context, dependable data and clinical oversight.

Guidance at the point of care

Augmented &
autonomous medicine

Virtual support, robotics, drones, assisted procedures and automated logistics that extend a team’s reach or operate with less direct support. The questions are what can be delegated, under which conditions and with what oversight.

Care with greater autonomy

Clinical systems
& readiness

Training, protocols, logistics and communication that sustain care when familiar support is limited. Continuity across teams, settings and time connects intervention, recovery and changing health needs.

Sustaining capability

These domains organize this project’s exploration. They overlap and draw on established specialties; they are not new credentials or formal specialty designations.

02 / Horizons

The frontier is
a condition, not a place.

Sometimes the hospital is distant.
Sometimes its infrastructure is disrupted.
Sometimes Earth itself is out of reach.
Sometimes care is nearby, but continuity is missing.

01

Remote & austere

Care shaped by distance, scarce supplies and limited access to specialists. The challenge begins with what a team can reliably sustain.

Wilderness & remote medicine
02

Expeditionary

Medical capability that moves with a mission. Small teams, portable diagnostics and coordinated care when evacuation cannot be assumed.

Explore the literature
03

Extreme & disrupted

Cold, heat, exposure and damaged systems change the conditions of care. Environmental protection and safe water belong alongside clinical intervention.

Environmental health in emergencies
04

Space & exploration

Medical planning for missions with constrained resupply, delayed communication and limited options for return. Greater autonomy becomes a design requirement.

NASA’s exploration medical framework

Across time / Distributed & longitudinal

Time is a condition of care.

Recovery evolves, conditions progress, teams change and access comes and goes. The care environment changes over time. The challenge is sustaining care through those changes, across encounters, settings and stages of life.

Care that stays connected.

Virtual care can bring clinical support closer. AI may help teams organize information, recognize changes and coordinate follow-through. Together with connected clinical teams, these tools could bridge gaps in access, expertise and continuity.

Post-intervention recovery is one starting point. Complex care, chronic conditions, aging at home and caregiver support also reveal where continuity can fail. Benefit depends on reliable support, clinical oversight and evidence for each use.

03 / What connects the field

Capability is more
than equipment.

A tool is only as useful as the system around it.

A portable scanner still needs power. A procedure needs trained hands, a workable environment and a plan for complications. A remote consultation needs a team able to act.

Protect the person

Environmental health, prevention and human performance are part of the clinical picture.

Bring understanding closer

Portable imaging and decision support can help address uncertainty where expertise is limited.

Make capability dependable

Training, logistics, protocols and resilient information systems turn individual tools into care that can be sustained as needs and circumstances change.

04 / The reading room

Research that opens
the conversation.

A starting collection of published work coauthored by John Pavlus, MD, and collaborators. Reviews, commentaries and letters are labeled by type; a proposal is not proof of clinical benefit.

Across the wider system

Teams, readiness, imaging and connected care.

Publication records checked September 19, 2026. Links lead to the original publications or PubMed records; some full texts require journal access. Summaries draw on available abstracts and publisher excerpts. Unpublished manuscripts are not included.

05 / Open questions

The next frontier
is a better question.

01

What care can a small team safely sustain when evacuation is delayed?

Define the clinical need, the limits of the team and the support required for the whole course of care.

02

How much guidance is enough to support greater autonomy?

Test tools with the people, conditions and failure modes they will encounter. Measure outcomes beyond a successful demonstration.

03

How can care remain dependable as needs, teams and settings change?

Study where continuity fails and whether virtual support, AI assistance and connected care can close those gaps. Test what demanding environments can teach everyday medicine.

06 / About this project

A wider lens
on what care can be.

Frontier Medicine is an independent educational project by John Pavlus, MD.

It begins with a clinical and research perspective in interventional radiology, then looks outward: toward the environmental, operational and human systems that determine whether care can reach someone and remain dependable over time.

The aim is to make the field easier to understand, connect adjacent disciplines and keep emerging possibilities in conversation with evidence.

For clinicians, researchers, engineers and anyone curious about the future of care.
