Sponsored by Sergio Gabriel Susmallian · Observational
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.
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.
257 studies on the registry are indexed under Hernia; 37 are open to participants now.
This study's enrollment of 4,500 is above the median of 120 across 85 observational studies indexed under Hernia.

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.

Exclusion Criteria:
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.
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.
Time frame: Baseline (at recognition of the occupational hernia claim)
Plan to share: No — Individual participant data will not be shared because the study is based on de-identified administrative records obtained from a national insurance database under institutional and data-use restrictions. The investigators are not authorized to distribute individual-level claimant data to external researchers. Aggregate study results may be reported in publications.
