This is the first large-scale study of US workers that describes the demographic and cost diffences between recurrent and nonrecurrent low back pain (LBP) disability claimants, using data from a large worker's compensation insurer.
Persons with at least one LBP claim in 1990 and one or more additional claims in 1990 to 1996 were defined as recurrent.
Persons with at least one LBP claim in 1990 but no subsequent claims were defined as noncurrent.
Fourteen percent of claimants were recurrent.
The percentage of recurrent claimants who were male (77.2%) was higher than the percentage that were female (22.8%). This difference was more pronounced in the younger age groups.
The median total cost for recurrent LBP claims in 1990 was 4% greater than for nonrecurrent 1990 LBP claims, whereas the mean cost was 48% less.
Most studies of LBP recurrence among US workers have followed single-corporation employees.
Our rate of recurrence was lower than these previously reported rates.
However, analysis of independent workers'compensation insurance company data may provide a more accurate assessment of LBP claim recurrence among US workers.
