The role of outcome measures in assessing change in the at-risk rheumatoid foot.

In common with other outcome measures, those for the at-risk rheumatoid foot need to be sensitive, specific and patient focussed, although currently these combined features are not available within one measure. There is also the issue of cross-validation with other commonly used measures to be considered. Both government policy and clinical need predicate development of suitable measures for the rheumatoid foot. In the first part of this paper, general issues relating to outcome measures and some government policy are considered and in the second, outcome measures relating to the at-risk rheumatoid foot are introduced alongside a discussion on the implications for practitioners.
