Living life precariously with rheumatoid arthritis - a mega-ethnography of nine qualitative evidence syntheses.

This is the second mega-ethnography, or synthesis of qualitative evidence syntheses using the methods of meta-ethnography. Future research should consider the proliferation of qualitative evidence synthesis in order to avoid duplication of research effort. Our model for rheumatoid arthritis has some important clinical implications that might be transferable to other musculoskeletal conditions.
