The impact of income support systems on healthcare quality and functional capacity in workers with low back pain: a realist review protocol.

Income support and healthcare systems are highly complex and fluid programmes. At the intersection between these systems are those with low back pain. By using realist review methods, we will provide explanatory rather than judgemental findings. The resulting multi-dimensional and contextual understanding of the impact of income support systems on important low back pain outcomes will provide valuable insight for future income support and healthcare policy development.
