An observational study of Hernia and Hernia Abdominal Wall, run by Sergio Gabriel Susmallian at 1 site in Israel.
Trial summary
This study examines recognized occupational hernia claims using existing national administrative records. The purpose is to describe how often hernia-related occupational claims occur and to evaluate their distribution according to worker characteristics, type of hernia, geographic area, and occupational factors.

Study population: The study population consists of individuals with recognized occupational hernia claims recorded in the national administrative database during the study period. The population includes claimants with hernia diagnoses recognized within the occupational-injury compensation system. Available demographic, geographic, diagnostic, claim-related, and disability information will be analyzed. Because this is a retrospective administrative study, no participants are recruited or contacted and no intervention is administered.
Who may be able to join
- Recognized occupational hernia claim recorded in the national administrative database during the study period.
- Hernia diagnosis documented as part of the occupational claim.
- Claim recognized within the occupational-injury/occupational-disease ---compensation system.
- Availability of sufficient administrative data for inclusion in the planned analyses.
Who cannot join
- Hernia records not recognized as work-related occupational claims.
- Claims outside the predefined study period.
- Records without sufficient diagnostic information to confirm or classify the hernia.
- Exact duplicate administrative records.

About this study
Official title: Geographic and Temporal Patterns of Recognized Occupational Hernia Claims: A Nationwide Retrospective Administrative Study
This study examines recognized occupational hernia claims using existing national administrative records. The purpose is to describe how often hernia-related occupational claims occur and to evaluate their distribution according to worker characteristics, type of hernia, geographic area, and occupational factors. The study will also examine patterns of disability and work-related consequences associated with these claims.
This is a retrospective observational study. No participants will receive an intervention or be contacted for the study. All analyses are based on previously collected administrative data.
Read the detailed description
This nationwide retrospective observational study will evaluate administrative records of recognized work-related hernia claims recorded in the National Insurance database between 2018 and 2026. The study is designed to characterize the burden and distribution of hernia-related occupational claims and to examine temporal and geographic variation in these claims.
Analyses will distinguish the number of claim records from the number of individual claimants and will evaluate patterns across administrative districts and local branches. Where available, demographic, clinical, claim-related, and disability characteristics will also be examined. Temporal analyses will assess changes in hernia-related occupational claims across calendar years and geographic analyses will identify variation in claim burden between regions.
Because the study is based on recognized occupational claims rather than direct measurement of workplace exposure, observed associations will be interpreted as patterns in occupational-claim burden and not as proof that a specific occupation or work activity caused the hernia. No intervention will be administered, and no participants will be contacted. All analyses will use previously collected administrative data.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| occupational hernias | Individuals with recognized occupational hernia claims recorded in the national administrative database during the study period. The cohort includes claimants with work-related hernia diagnoses and associated demographic, geographic, claim-related, and disability information, where available. This is a retrospective observational cohort; no intervention or treatment is administered as part of the study. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Distribution of Recognized Occupational Hernia Claims
Number and proportion of recognized occupational hernia claims identified in the national administrative database, overall and according to hernia type and available claim characteristics.
Measured: Baseline (at recognition of the occupational hernia claim)

Questions about this trial
What is this clinical trial studying?
An observational study of Hernia and Hernia Abdominal Wall, run by Sergio Gabriel Susmallian at 1 site in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 23 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Distribution of Recognized Occupational Hernia Claims (time frame: Baseline (at recognition of the occupational hernia claim)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07831005, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2026.
