Heat illness is already in your records. It’s filed under something else.
Evolia Health is a heat health research and evaluation practice. We find heat cases hidden in injury and workers’ compensation records, evaluate whether heat programs work, and analyze serious heat events so they don’t happen again.
| Job | Recorded as | On review |
|---|---|---|
| Grounds crew | Fall from mower | Fainted in heat before fall |
| Line technician | Dehydration | Heat exhaustion |
| Road crew | Hand laceration | Not heat-related |
| Sanitation collector | Cardiac event | Review heat exposure at onset |
| School maintenance | First-aid log only | Heat cramps, never logged |
Who we work with
Organizations with outdoor workers in hot climates, and the partners who insure, advise, and fund them.
- County and city risk managersParks, public works, utilities, and sanitation crews
- School districtsGrounds, maintenance, and transportation staff
- UtilitiesLine, field, and plant workers
- Self-insurance and risk poolsLoss control across member employers
- Workers’ compensation carriersLoss-control and safety consulting teams
- Health departments and universitiesPrograms that need an external evaluator
Three questions we answer
Each engagement has a fixed scope and ends in a written report your team can act on.
Heat illness records audit
Are heat illnesses being missed in our injury records?
Heat illness is often recorded as a fall, a cardiac event, dehydration, or not at all. We review workers’ compensation claims, OSHA 300 logs, first-aid logs, and EMS calls where available, and identify the cases that were missed or misclassified.
You receive
- Your true heat illness caseload
- Patterns by department, month, and job type
- Documentation gaps that would raise questions in an OSHA inquiry
- A prioritized list of fixes
Best for: risk managers, school districts, utilities, and risk pools reviewing loss data.
Program evaluation (RE-AIM)
Is our heat program working?
For organizations that already run a heat program: counties with heat officers, grant-funded initiatives that owe their funder an evaluation, and employers that launched a program after an incident. We use the RE-AIM framework to measure who the program reaches, whether it works, how widely it’s adopted, how consistently it’s delivered, and whether it lasts.
You receive
- An evaluation plan and measures matched to your program
- Findings across Reach, Effectiveness, Adoption, Implementation, and Maintenance
- A report ready to share with leadership or funders
- Specific recommendations for the next season
Best for: public agencies, grant-funded programs, and employers with an existing heat plan.
Post-incident review
What went wrong after a serious heat event, and how do we prevent the next one?
A written root-cause analysis of a serious heat event: the conditions, decisions, and system gaps that led to it, and the changes that address them.
You receive
- A reconstructed timeline of the event
- Contributing factors at the worker, crew, and organization level
- Corrective actions ranked by impact and feasibility
Post-incident reviews are scoped as internal quality improvement. Evolia does not provide litigation support or expert witness services.
How a records audit works
- ScopeWe agree on the records, years, and departments to review, and sign a data use agreement.
- Records transferYou share records through a secure method you approve. We provide a data request template, and we can work with de-identified data.
- Case reviewEvery record is screened for signs of heat illness, including cases coded under other causes.
- ReportYou receive a written report with findings and prioritized fixes, plus a one-page summary for leadership.
About Evolia Health
Evolia Health LLC is a heat health research and evaluation practice for employers, public agencies, and funders with workers in hot environments.
Evolia combines field epidemiology with implementation science. Records audits rely on case-finding methods that look past how an injury was coded to what actually happened. Program evaluations use the RE-AIM framework to measure whether a heat program reaches the people it’s meant to protect and keeps working after launch.
Common questions
What is a heat illness records audit?
A heat illness records audit is a systematic review of an employer’s injury and illness records, including workers’ compensation claims, OSHA 300 logs, first-aid logs, and EMS calls, to find heat-related cases that were missed or recorded under another cause. The result is an accurate count of heat illness, the patterns behind it, and a prioritized plan to fix documentation and prevention gaps.
Why are heat illnesses missed in injury records?
Heat illness often shows up as dizziness, fainting, cramps, or confusion, so the record may capture what happened next, such as a fall or a vehicle incident, or a related diagnosis like dehydration or a cardiac event, instead of the heat exposure behind it. Cases treated only with first aid generally do not reach the OSHA 300 log at all.
What records does Evolia need for an audit?
Most audits use workers’ compensation claims, OSHA 300 and 301 records, and first-aid logs for two to five years. EMS or occupational health records add detail when available. Evolia provides a data request template and can work with de-identified records.
How is our data protected?
Every engagement starts with a data use agreement. Records are stored securely, used only for the agreed analysis, and returned or destroyed when the engagement ends. Findings are reported in aggregate, not by individual worker.
Is there a federal OSHA heat standard?
Not yet. OSHA proposed a federal heat injury and illness prevention rule in 2024, and it has not been finalized. In the meantime, OSHA enforces heat hazards through the General Duty Clause and its National Emphasis Program on heat, which makes accurate heat illness records more important, not less.
