Clinical research
Evaluates structured outdoor exposure as a clinical intervention in defined populations, against appropriate control conditions, under IRB oversight.
Stage: four clinical protocols developed; none enrolling.
Value-Based Outdoor Healthcare℠ investigates how measurable environmental exposure may influence biological regulation, disease trajectories, health outcomes, and the total cost of care.
Most care follows a familiar sequence. A person develops symptoms, receives a diagnosis, is treated, and the outcome is recorded.
That sequence begins after disease is visible. It rarely records the conditions a patient returns to between visits: light, movement, air, terrain, social context, and the chronic stress load of daily life.
VBOHC asks a prior question. If those conditions shape biology, they belong earlier in the sequence, where they can be measured, varied, and studied.
The research program seeks to determine whether environmental exposure can become a measurable, and potentially modifiable, component of healthcare delivery.
VBOHC hypothesizes that environmental exposures, including nature exposure, physical activity, social context, circadian conditions, stress regulation, and opportunities for behavioral adaptation, may influence biological systems involved in disease progression and recovery.
This is a hypothesis under investigation. Links between columns are research questions, graded by the strength of available evidence, and are not presented as established causal pathways.
The unanswered question is whether we are equally good at changing the conditions that produce disease.
Chronic disease and multimorbidity now define much of clinical practice. Cardiometabolic disease, chronic pain, depression and anxiety, and neurocognitive decline are managed across fragmented settings, often for decades, while utilization and cost continue to rise.
Research on social and environmental determinants of health has shown that where and how people live is associated with health outcomes. What remains less developed is a clinical method for treating environment as something a care team can prescribe, dose, measure, and pay for.
VBOHC treats that gap as a systems and research question. It does not assume the answer.
Each domain is organized around a research question, a defined population, a measurable exposure, and outcomes that matter to patients and payers.
Every study is labeled with its actual stage. No VBOHC study is currently enrolling participants.
Medicine has learned to measure
VBOHC asks whether healthcare should also measure
If environment changes biology, environment belongs in the healthcare equation.
These fields share settings and vocabulary. They differ in purpose, and in how each treats the environment.
| Field | Primary purpose | The environment is treated as |
|---|---|---|
| Outdoor recreation | Recreation | A setting for leisure |
| Outdoor therapy | Therapeutic activity | A context for an activity |
| Wilderness therapy | Behavioral intervention | A therapeutic milieu, often residential |
| Lifestyle medicine | Health behavior modification | An influence on behavior |
| Environmental health | Study of environmental determinants | An exposure to be characterized, usually a hazard |
| Value-Based Outdoor Healthcare | Integrate measurable environmental exposure into clinical care, disease trajectory research, outcomes measurement, and healthcare financing | A clinical variable that is prescribed, dosed, measured, and linked to outcomes and cost |
OMOHC is proposing a research and clinical field station on privately held land in Ogden Valley, adjacent to national forest and mountain trail systems. The facility is in the entitlement phase and has not been built.

A staged research program that moves from measurement to mechanism to clinical outcomes to health economics, with each stage able to confirm or falsify the one before it.
The VBOHC research agenda asks whether structured, dosed, and instrumented environmental exposure, delivered under protocol, produces changes in disease trajectory. To count as support for the hypothesis, those changes would need to be:
Each research stream below addresses one link in that chain. Evidence is graded, and established findings, inferences, hypotheses, and commercial assumptions are reported separately.
OMOHC also maintains an explicit account of how VBOHC could be wrong: which results would weaken or falsify the hypothesis, and how the program would respond.
Evaluates structured outdoor exposure as a clinical intervention in defined populations, against appropriate control conditions, under IRB oversight.
Stage: four clinical protocols developed; none enrolling.
Studies the physiological pathways through which exposure might act, including autonomic regulation, HPA-axis activity, inflammation, and sleep and circadian biology.
Stage: research design.
Develops methods to quantify exposure: duration, frequency, intensity, vegetation, light, elevation, terrain, and weather, captured by sensors and geospatial data.
Stage: measurement architecture specified.
Asks whether exposure is associated with changes in the slope of disease-relevant measures over time, not only with short-term symptom relief.
Stage: longitudinal registry concept.
Builds a standardized outcome set so results can be compared across sites, conditions, and delivery models. A 70-measure VBOHC Core Outcome Set has been drafted and is the subject of a Delphi consensus study.
Stage: consensus protocol developed.
Tests whether measured clinical change translates into lower utilization and total cost of care. Economic effects are treated as hypotheses until observed in claims and utilization data.
Stage: economic model and registry design; no outcome data.
A PRISMA-aligned systematic review of nature-based and outdoor clinical interventions establishes what current literature does and does not support.
Stage: protocol OMOHC-SR-2026-001 developed; PROSPERO registration pending.
Protocols and proposed studies, filterable by domain and stage. Final design parameters are set only in an IRB-approved protocol.
Home / VBOHC
An environment-first healthcare research and delivery framework. VBOHC asks what happens to healthcare when the environment itself is treated as a modifiable determinant of biological and disease trajectory.
Value-Based Outdoor Healthcare is a framework for integrating measurable environmental exposure into clinical care, disease trajectory research, outcomes measurement, and healthcare financing.
Its organizing principle is Environment First. Biology Second. Before asking what is wrong inside the patient, VBOHC asks what the patient's environment is doing to the systems that regulate stress, sleep, metabolism, pain, mood, and cognition, and whether that environment can be changed on purpose.
VBOHC is not outdoor recreation, wilderness therapy, a wellness program, or a resort concept. It is a research program with a clinical model attached, and its claims are held to the standards of clinical research.
Framework originated by Anna Hallows, August 2021. Archived record: doi.org/10.5281/zenodo.18966778.
Environment is a modifiable determinant of disease trajectory.
Stated as a testable claim: structured, dosed, and instrumented environmental exposure, delivered under protocol, produces changes in disease trajectory that are larger than attention or activity control, durable beyond the exposure period, and detectable in objective biomarkers.
This is a disease-modification hypothesis, not a claim about symptom relief. It may be wrong, and the research program is designed to find out.
VBOHC delivers environmental exposure the way medicine delivers any other intervention: assessed, prescribed, delivered, measured, and adjusted.
A prescription is only useful if it can be specified and measured. VBOHC treats nature exposure as a dose with identifiable components: how long, how often, how intense, and in what kind of environment.
The Nature Dose Engine™ is the proposed method for combining those components with the patient's physiological response into an individualized dose. It is a research tool under development and has not been clinically validated.
It may be one of its variables.
The conditions a patient happens to live and receive care in. Context is described, sometimes adjusted for statistically, and rarely changed by the care team.
An environment chosen, structured, and delivered on purpose, with a defined dose, a measured response, and a comparison condition. Intervention can be studied, and if effective, prescribed.
VBOHC's methodological contribution is dose-controlled environmental exposure: moving the environment from the first category into the second so that its effects can be tested rather than assumed.
Traditional fee-for-service
VBOHC
Fee-for-service pays for activity. Value-based payment pays, at least in part, for results. An intervention that changes disease trajectory is most visible in a payment model that rewards trajectory: lower utilization, fewer complications, better function over time.
VBOHC is designed to be evaluated in that frame, with relevance to accountable care, population health management, chronic disease management, Medicare and Medicaid innovation, and employer health.
OMOHC is preparing proposals to test VBOHC within existing value-based payment pathways. No payer, CMS, CMMI, HHS, or other agency has endorsed, funded, or adopted VBOHC.
The VBOHC economic case rests on a chain of claims: that measured clinical change is real, that it persists, and that it reduces downstream utilization enough to offset delivery cost. Each link is a hypothesis.
The proposed VBOHC National Outcomes Registry would link clinical outcomes, utilization, claims, and environmental exposure data so that economic effects can be observed rather than projected.
OMOHC publishes illustrative financial models as models. They are never presented as observed savings or outcomes.
| Dimension | Conventional care | VBOHC (proposed) |
|---|---|---|
| Starting point | Symptoms and diagnosis | Risk, biology, and environmental exposure |
| Role of environment | Context, occasionally documented | Prescribed, dosed, and measured variable |
| Setting | Clinic, hospital, home | Clinic plus qualified outdoor treatment environments |
| Measurement | Episodic, visit-based | Continuous where feasible: wearables, patient-reported outcomes, biomarkers, exposure data |
| Unit of success | Episode resolved | Change in disease trajectory |
| Payment alignment | Volume of services | Outcomes and total cost of care |
Home / Science
VBOHC draws on established fields. Each area below states the research question VBOHC brings to it, not a settled conclusion.
What contributes to disease trajectories?
VBOHC examines environmental and behavioral conditions as upstream contributors alongside genetic, clinical, and social factors.
How may environmental exposures interact with biological regulation?
A long-horizon question about whether sustained changes in exposure are reflected in markers of gene regulation.
How do chronic stress and environmental conditions affect physiology?
Focus on allostatic load, HPA-axis activity, and inflammatory signaling.
Can environmental intervention measurably alter autonomic state?
Heart rate variability and resting heart rate provide continuous, wearable-accessible measures.
How do light, activity, sleep, and environmental timing interact?
Outdoor light exposure and activity timing as candidate levers for sleep and metabolic regulation.
How does environment interact with brain and behavioral systems?
Attention, mood regulation, cognition, and neurological function under varying environmental conditions.
Does structured exposure change metabolic markers beyond what activity alone explains?
Glycemic control, blood pressure, and body composition measured against activity-matched comparison.
Can beneficial exposures be characterized with the rigor applied to hazards?
Adapting exposure science methods, including GIS, vegetation indices, and air and light measurement, to health-promoting environments.
Where do environmental exposure and social conditions overlap?
Access to safe outdoor space is shaped by income, transportation, and neighborhood, and is studied as such.
Do measurable outcomes translate into lower total cost of care?
Tested through utilization and claims data, never assumed from clinical change alone.
How do biological, relational, environmental, and healthcare systems interact?
Feedback loops, emergent behavior, and closed-loop control as frames for chronic disease.
VBOHC's conceptual model, the Nature-Regulated Human System, integrates Bowen Family Systems Theory with environmental health science. Bowen theory describes how chronic anxiety moves through relational systems and how differentiation of self shapes an individual's capacity to regulate under stress.
VBOHC extends that systems view outward: if relational systems carry chronic stress, the physical environment may be another system that either amplifies or buffers it.
These are theoretical frameworks that generate hypotheses. They are not presented as established causal mechanisms.
If environmental exposure affects health, then unequal access to health-promoting environments is a health inequity. VBOHC research asks how access to the following is distributed, and for whom it is missing:
Safe outdoor spaceClean airGreen spacePhysical activityTransportationHealthcareHealthy foodSocial connection
Nature access alone does not resolve health inequity, and VBOHC does not claim that it does. The research program treats access, transportation, cost, safety, disability, and cultural relevance as design requirements, and reports outcomes by population so that gaps are visible rather than averaged away.
Home / Clinical programs
Four clinical domains, each with a research question, a target population, a defined exposure, and a measurement plan. All programs are in development and none currently deliver care.
OMOHC is developing an integrated intensive outpatient program (IOP) that addresses mental and physical health together, as a first VBOHC delivery model. Curriculum work includes 8-week programs for chronic pain, cardiometabolic health, emotion regulation, and ME/CFS. In development
Home / Data and technology
The VBOHC Clinical Intelligence Platform is a proposed research and clinical architecture for capturing environment, physiology, and outcomes in one record. It is under development and is not a cleared medical device.
Proposed architecture
The platform is designed as a seven-layer data architecture that carries information from capture through indexing, modeling, and outcomes reporting. Its purpose is to make environmental exposure and physiological response legible to clinicians, researchers, and payers in the same record.
Underlying methods are the subject of a U.S. patent application in preparation by Oak Mountain Outdoor Healthcare, LLC.
VBOHC organizes measurement into validated instruments that clinicians already use, and proprietary composite indices that are components of the proposed platform.
Seven core indices applied across all four clinical domains.
Four indices aligned to specific clinical domains.
Three indices that model the coupling between environmental exposure and therapeutic response.
| Domain | Example measures | Status |
|---|---|---|
| Physiological | Heart rate, heart rate variability, blood pressure, sleep, activity | Established measures |
| Metabolic | HbA1c, glucose, continuous glucose monitoring, lipid and metabolic panels | Established measures |
| Inflammatory | Inflammatory biomarkers such as CRP and IL-6, where clinically appropriate | Established measures |
| Psychological | PHQ-9, GAD-7, WHO-5, PROMIS instruments | Validated instruments |
| Environmental | Exposure duration, NDVI vegetation index, GIS location, altitude, weather, light | Established data sources, VBOHC method in development |
| Behavioral | Activity, sleep, adherence, movement, social exposure | Established data sources, VBOHC method in development |
| VBOHC composite indices | Tier 1 to Tier 3 indices described above | Proprietary, not yet validated |
Instead of documenting whether a patient went outside, VBOHC attempts to quantify exposure and relate it to the patient's measured response.
Duration, frequency, intensity, elevation, terrain, vegetation, daylight, temperature, weather, physical activity, social context, perceived stress, and physiological response.
The engine has not been clinically validated. Its dose model will be tested against measured outcomes in IRB-approved research before any clinical use. Not validated
The VBOHC Patient Digital Twin is a proposed research and technology architecture, not an established clinical product.
Research concept
A proposed modeling layer that estimates each patient's expected trajectory and compares it with observed change during and after exposure.
Research conceptProposed prompts for dose adjustment and escalation, reviewed by clinicians. Any clinical deployment would follow applicable FDA guidance on decision-support software.
Research conceptConsumer and research-grade wearables provide continuous heart rate, HRV, sleep, and activity data. Device selection will be protocol-specific.
PlannedThese interactive prototypes show the intended data views. Every value is simulated.
Planned, not yet built
The platform is being designed to exchange data using HL7 FHIR and SMART on FHIR, so that VBOHC measures can appear inside the clinical systems care teams already use, including Epic, Oracle Health, and athenahealth environments.
Planned data sources include Apple Health, Garmin, Fitbit, Oura, WHOOP, continuous glucose monitoring systems, GIS platforms, and public environmental datasets.
None of these integrations currently exists. Names are listed to describe design intent and do not indicate any partnership or endorsement.

Home / Research campus
Ogden Valley, Utah. A proposed research and clinical field station where environmental exposure can be delivered, measured, and studied under protocol.
Nothing on this page has been built. The campus is a proposal in the land-use entitlement phase, subject to local approvals.
The proposed field station sits on two privately held parcels totaling 2.99 acres in Ogden Valley, adjacent to the Nordic Valley area and the Uinta-Wasatch-Cache National Forest. Mountain terrain, forest, water, snow, and four distinct seasons make the setting suited to studying exposure across conditions.
The concept is a single elevated day facility, designed above the floodplain with no encroachment into the creek's riparian corridor, with outdoor treatment paths organized around the four clinical domains. There is no overnight lodging and no surface parking lot; access is proposed by shuttle from an off-site park-and-ride.
The site is intended as a prototype: a first facility whose design, measurement systems, and operating model could be standardized for other settings.
| Component | Description | Status |
|---|---|---|
| Site | Two privately held parcels, 2.99 acres, with site control established | Existing |
| Setting | Adjacency to national forest land and mountain terrain | Existing |
| Day facility | Approximately 40,000 SF elevated clinical, research, and education building | Proposed |
| Clinical spaces | Outpatient clinical, rehabilitation and movement, behavioral health, and cardiometabolic program space | Proposed |
| Outdoor treatment environments | Four domain paths and outdoor treatment areas on the private parcels | Proposed |
| Research and education | Research space, environmental monitoring, education and conference rooms | Proposed |
| Shuttle access | Off-site park-and-ride with shuttle service | Planned |
| National Outcomes Registry | Linked clinical, utilization, and exposure data across sites | Research concept |
| Use of adjacent public land | Any use of national forest land would require federal authorization | Not authorized, to be determined |
Site plans and architectural concept boards will be added here as entitlement documents are finalized.
