The SVAI compared with previous studies
MUSCULOSKELETAL DISORDER
The results from the MI-NAV trial support the findings of the SWAP trial indicating that vocational advice could reduce sickness absence among workers with musculoskeletal disorder. However, our results were not statistically significant after adjusting for possible confounders. The SWAP trial showed a reduction of 5 days of sickness absence over 4 months of adding a vocational advice intervention to best current primary care in the UC.Although the SVAI was mainly delivered according to protocol, some intervention elements were poorly implemented.
