A descriptive study of recurrent low back pain claims

Area of Science:

• Occupational Health
• Epidemiology
• Biostatistics

Background:

• Low back pain (LBP) is a significant cause of disability among US workers.
• Understanding the characteristics of recurrent LBP claims is crucial for effective management and cost containment.
• Previous studies on LBP recurrence have often been limited to single-corporation employee data.

Purpose of the Study:

• To describe demographic and cost differences between recurrent and nonrecurrent LBP disability claimants in a large US worker population.
• To analyze recurrence rates using data from a workers' compensation insurer, offering a broader perspective than single-employer studies.

Main Methods:

• Utilized data from a large workers' compensation insurer for claims between 1990 and 1996.
• Defined recurrent LBP claimants as those with at least one LBP claim in 1990 and additional claims between 1990-1996.
• Defined nonrecurrent LBP claimants as those with a 1990 claim but no subsequent claims.

Main Results:

• Fourteen percent of claimants experienced recurrent LBP.
• Recurrent claimants were predominantly male (77.2%), with this disparity more pronounced in younger age groups.
• Median total costs for recurrent LBP claims were 4% higher, but mean costs were 48% lower compared to nonrecurrent claims.

Conclusions:

• Recurrent LBP disability disproportionately affects male and younger workers.
• The cost structure of recurrent LBP claims differs significantly from nonrecurrent claims.
• Analysis of large, independent workers' compensation data provides a more comprehensive understanding of LBP recurrence in the US workforce.
