Early Predictors of Lumbar Spine Surgery After Occupational Back Injury
Results From a Prospective Study of Workers in Washington State
Objective. To identify early predictors of lumbar spine surgery within 3 years after occupational back injury.
Results. . . Reduced odds of surgery were observed for those younger than 35 years, females, Hispanics, and those whose first provider was a chiropractor. Approximately 42.7% of workers who first saw a surgeon had surgery, in contrast to only 1.5% of those who [first] saw a chiropractor. . .
Conclusion. . . There was a very strong association between surgery and first provider seen for the injury even after adjustment for other important variables.
