Environmental and Geographic Patterns of Occupational Injuries
Israel350,000 participantsStarted 2020-01-01
Plain-language summary
This study will determine whether extreme ambient temperatures increase the incidence and severity of occupational injuries in Israel, and we request Helsinki Committee approval to conduct the analysis using de-identified National Insurance and historical meteorological data, with a waiver of informed consent. The project will link the date, time, and geographic location of recognized occupational accidents with corresponding historical temperature and humidity measurements. The study is retrospective, observational, and involves no direct contact with participants, no intervention, and no alteration of medical care or benefit eligibility.

Inclusion Criteria:
* Individuals aged 18 years or older with an occupational injury recognized by the National Insurance Institute.
* Occupational injury occurring between January 1, 2020, and December 31, 2024.
* Injury occurring at the workplace, during occupational travel, or while commuting to or from work.
* Valid injury date and geographic information sufficient to assign the accident to one of the seven predefined geographic-climatic regions and the nearest representative meteorological station.
* Meteorological measurements available for the injury period and eligible matched control periods.
For time-specific analyses, a valid recorded accident time permitting linkage to the closest preceding three-hour meteorological observation.
Exclusion Criteria:
* Occupational diseases, repetitive-exposure conditions, or gradual-onset disorders without a clearly defined accident date.
* Rejected, withdrawn, or unconfirmed occupational-injury claims.
* Missing or invalid accident date or geographic information preventing linkage with meteorological data.
* Accidents occurring outside the predefined geographic-climatic regions or beyond the prespecified maximum distance from an eligible meteorological station.
* Duplicate or administratively repeated records referring to the same occupational-injury event.
* Injury events for which no eligible matched control periods or corresponding meteorological measurements are available.
* Individuals younger than 18 years.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
