Relationship Between Age, Tenure, and Disability Duration in Persons With Compensated Work-Related Conditions.

Area of Science:

• Occupational Health
• Rehabilitation Medicine
• Workplace Safety

Background:

• Work-related injuries and illnesses can lead to prolonged disability, impacting both individuals and the economy.
• Understanding factors influencing disability duration is crucial for effective return-to-work strategies.
• Previous research has explored age and tenure as potential predictors of recovery time.

Purpose of the Study:

• To investigate the independent and interactive effects of employee age and job tenure on the duration of disability following a work-related injury or illness.
• To quantify the relative importance of age versus tenure in predicting disability length.

Main Methods:

• Analysis of a large administrative dataset comprising 361,754 workers' compensation claims.
• Application of random-effects models to estimate the relationships between age, tenure, and disability duration.

Main Results:

• Age demonstrated a stronger association with disability duration than job tenure.
• A significant interaction effect between age and tenure was identified.
• Disability duration showed minimal variation with tenure in younger workers, increased with lower tenure in midlife, and rose with higher tenure in older workers.

Conclusions:

• Age is a more dominant factor than tenure in determining disability duration.
• The influence of age on disability duration is moderated by an individual's tenure.
• Both age and tenure are critical determinants in the work-disability process, necessitating tailored interventions.
