An observational study in Occupational Injury and Work-Related Disability, sponsored by Sergio Gabriel Susmallian. Completed at 1 site in Israel. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-03.
Sponsored by Sergio Gabriel Susmallian · Observational
This observational study will examine patterns of disability following occupational injuries using national administrative records from 2020 through 2024.
The study will evaluate how disability status changes over time after a recognized work-related injury. Particular attention will be given to temporary disability, progression to permanent disability, disability percentage, repeated disability determinations, and recurrent occupational injury claims.
The study will also examine whether characteristics such as age, sex, type of occupational injury, statutory impairment category, geographic region, and year of injury are associated with different disability trajectories.
No treatment or intervention will be assigned as part of this study. All information will be obtained retrospectively from existing administrative records.
Occupational injuries may result in short-term functional impairment, prolonged temporary disability, permanent disability, or repeated disability determinations. However, large-scale longitudinal information describing how disability status evolves after occupational injury is limited.
This retrospective observational cohort study will use national administrative data on recognized occupational injury claims recorded between January 1, 2020, and December 31, 2024. The database includes chronological claim and disability-determination records, statutory impairment classifications, assigned disability percentages, and temporary or permanent disability status.
The primary objective is to characterize longitudinal disability trajectories following occupational injury. The study will evaluate transitions from temporary to permanent disability and the time from the first observed occupational injury claim to permanent disability determination.
Secondary objectives include evaluating the severity of permanent disability, changes in disability percentage over time, repeated temporary or permanent disability determinations, recurrent occupational injury claims, and patterns of disability progression.
Where available, analyses will examine differences according to demographic characteristics, occupational injury category, statutory impairment classification, geographic region, and calendar year.
Claim records belonging to the same individual will be linked using anonymized claimant identifiers to reconstruct the chronological sequence of occupational injury claims and disability determinations. Time-to-event and longitudinal statistical methods will be used to identify factors associated with permanent disability and other disability trajectories.
Because the study uses previously collected administrative data, participants will not undergo study-specific interventions, treatment assignments, or additional clinical procedures.

Counted across the registry records on this site, refreshed daily.
The study population will include individuals with recognized occupational injury claims recorded in the national administrative database between January 1, 2020, and December 31, 2022. Eligible claimants will be followed through December 31, 2024 using chronologically linked administrative records. The cohort will include all eligible claimants with valid anonymized identifiers and sufficient date information to reconstruct claim and disability-determination histories. Data will include temporary and permanent disability status, assigned disability percentages, statutory impairment classifications, and repeated claim or disability-determination records. No participants will be recruited prospectively.

Exclusion Criteria:
Individuals with recognized occupational injury claims recorded in the national administrative database between January 1, 2020, and December 31, 2024. Chronologically linked claim and disability-determination records will be used to evaluate temporary and permanent disability status, disability percentage, repeated determinations, and disability progression over time.
Other: Recognized Occupational Injury
The exposure of interest is a recognized work-related injury recorded in the national administrative claims database. No intervention, treatment, or procedure is assigned as part of the study. Existing records will be analyzed to characterize subsequent temporary and permanent disability trajectories.
Time From First Observed Occupational Injury Claim to Permanent Disability
Time in days from the first observed occupational injury claim to the first recorded permanent disability determination. Participants without a permanent disability determination will be censored at their last available record or December 31, 2024, whichever occurs first.
Time frame: From the first observed occupational injury claim until the first permanent disability determination or end of follow-up, up to 5 years
Plan to share: No — Individual participant data will not be shared because the study uses de-identified administrative records obtained from a national insurance database under data-use and confidentiality restrictions. The investigators are not authorized to redistribute participant-level records. Aggregate results and summary statistical outputs may be reported in publications.
