Evidence
What does the existing research actually demonstrate and what does it not establish?
Evidence-led environmental health · Scientific Validation
Know what the evidence actually supports.
Environmental health technologies can make important claims about air, water, surfaces, infection prevention, and the built environment. EvidentWorks helps organizations understand those claims through disciplined scientific evaluation, supported by our scientific validation partner, OnSite Scientific.
Scientific validation
Evidence before adoption.
Product specifications and marketing claims are only part of a decision. Organizations also need to understand what was tested, how it was measured, where limitations remain, and whether the evidence is relevant to the environment where a technology will actually be used.
Methodology
Were the right variables measured under conditions appropriate to the question being asked?
Environment
How might people, workflows, room conditions, equipment, and building systems affect performance?
Application
Do the findings support the intended use case, claims, operating requirements, and next decision?
Our scientific validation partner
Meet OnSite Scientific.
OnSite Scientific is a multidisciplinary research and consulting group focused on healthcare's built environment. Its team brings together scientists, engineers, and medical professionals with experience in environmental and clinical microbiology, infection prevention, healthcare infrastructure, environmental quality, testing, measurement, and clinical operations.
That range matters because an environmental health question rarely belongs to one discipline. Airflow can interact with room configuration. Clinical activity can change particle and microbial conditions. Engineering performance can shape what is measured at the point of care. A stronger evaluation considers those factors together.
For EvidentWorks, OnSite adds specialized scientific and technical depth when a technology or environmental question requires a more rigorous investigation than a document review alone.

EvidentWorks + OnSite
Scientific expertise connected to real-world decisions.
The relationship is complementary: EvidentWorks starts with the organizational need and decision context; OnSite contributes specialized research, testing, engineering, microbiology, and environmental expertise where deeper scientific evaluation is appropriate.
EvidentWorks
- Starts with the organizational need, intended environment, and use case.
- Reviews available evidence and helps define the questions that need answering.
- Connects scientific findings to practical decision support.
- Supports the path toward responsible implementation and ongoing learning.
OnSite Scientific
- Brings specialized scientific, clinical, infection-prevention, and engineering expertise.
- Supports appropriate testing approaches, measurements, and environmental assessment.
- Conducts or contributes to scientific investigation where the question calls for it.
- Analyzes findings and helps clarify what conclusions the evidence can and cannot support.

The validation process
From a product claim to a decision-ready understanding.
Not every question requires new laboratory testing or a research study. The work is scoped to the claim, the evidence already available, the intended environment, and the decision that needs to be made.
Define
Clarify the question.
Define the technology, intended application, claims, environment, and decision to be supported.
Review
Examine the record.
Review research, testing, technical information, safety considerations, and known limitations.
Design
Choose the right method.
Determine whether more evaluation is needed and define variables, conditions, and success criteria.
Validate
Test where appropriate.
Conduct or coordinate scientific evaluation with qualified expertise, including OnSite Scientific where appropriate.
Translate
Turn findings into clarity.
State what the evidence supports, where limits remain, and what should be considered next.
Research in context
Measure the environment as it actually operates.
Environmental performance can change as people enter a room, equipment moves, procedures begin, doors open, airflow shifts, or building systems respond. OnSite's published work reflects this dynamic view of healthcare environments rather than treating the room as a static backdrop.
OnSite has published a methodology using Environmental Quality Indicators (EQIs) to assess multiple conditions in dynamic operating-room environments. Its described EQIs include temperature, humidity, particle load, microbial contamination, pressurization, air velocity, and air distribution, measured during simulated procedures to create a more complete picture of environmental quality.
People & proceduresOccupancy, movement, clinical activity, and workflow.
Air & particlesVelocity, distribution, particulate conditions, and pressure.
Microbial conditionsEnvironmental and clinical microbiology measurements where relevant.
Room & equipmentConfiguration, placement, and the physical care environment.
Building systemsVentilation and other engineering systems that shape conditions.
OperationsMaintenance, practices, controls, and real-world use.
Multidisciplinary evaluation
Environmental health requires more than one discipline.
OnSite's value is not a single test. It is the ability to examine environmental questions through scientific, clinical, microbiological, operational, and engineering lenses.
1
Scientific Research
Study design, evidence review, measurement, and interpretation grounded in the question being evaluated.
2
Microbiology & Infection Prevention
Environmental and clinical microbiology, particle and microbial quality testing, and infection-prevention context.
3
Engineering
Healthcare infrastructure, ventilation, controls, commissioning, environmental conditions, and system performance.
4
Clinical Context
Understanding how care teams, procedures, equipment, and workflows interact with the environment.
5
Data & Analysis
Statistical analysis, analytics, reporting, and interpretation that make measurements useful for decisions.
Who we work with
Validation for teams making consequential environmental decisions.
Healthcare Organizations
Evaluate environmental technologies and interventions before or during adoption, with attention to clinical, operational, facilities, and evidence considerations.
Education & Institutional Environments
Understand whether environmental technologies are appropriate for intended spaces, operating conditions, and desired outcomes.
Environmental Health Technology Companies
Strengthen the evidence behind promising technologies and better understand the environments, claims, and use cases the evidence can support.
Built-Environment & Facility Teams
Evaluate environmental performance in the context of infrastructure, ventilation, operations, maintenance, and real-world conditions.
Decision-ready evidence
More than a pass or fail.
EvidentWorks views scientific evaluation as a way to create clarity not simply award a stamp of approval. A useful result explains what is supported, what is uncertain, and what the next decision should account for.

The EvidentWorks standard
Scientific rigor is part of how we make better decisions.
Scientific evaluation supports the broader EvidentWorks process. Evidence is considered alongside safety, quality, real-world performance, operational feasibility, transparency, known limitations, and the need to keep learning from outcomes after adoption.
Science is not a standalone exercise. It helps determine whether a solution should be considered, where it fits, what conditions matter, and what an organization should understand before moving forward.
Evidence is our minimum standard.
Before EvidentWorks helps advance a solution, the decision should be grounded in the strongest practical understanding available.
