Scand J Rheumatol. 2009 Aug 27; 1-7Hestbaek L, Rasmussen C, Leboeuf-Yde CObjectives: Financial compensation has been shown to be a negative prognostic factor for pain and disability in patients with neck or low back pain. It is unclear whether this association is causal and to what extent it hampers return to work. The objective of this study was to assess the direct influence of a financial compensation process on the ability to remain in regular employment in patients with suspected disc herniation. Methods: A prospective cohort study with a register-based follow-up at 1, 3, and 5 years after baseline was carried out at two multidisciplinary, non-surgical spine clinics in two public hospitals in Denmark. The study population comprised consecutive patients in regular employment with neck pain radiating to the arm or low back pain radiating to the leg. The exposure variable was any type of claim for financial compensation for the actual low back/leg or neck/arm pain. The outcome measure was receiving income compensation benefits. This information was obtained through national registers. Follow-up points were 1, 3, and 5 years after inclusion. Results: The study included 1243 low back pain patients and 202 neck pain patients. The odds ratio, adjusted for relevant confounders, of receiving income compensation benefits in case of baseline financial claim was approximately 2 for low back/leg pain patients and about 4 for neck/arm pain patients at 1, 3, and 5 years. Conclusions: In employed patients, a claim for financial compensation for low back or neck pain with radiating pain was found to be independently associated with receipt of income compensation benefits after 1, 3, and 5 years.
