Purpose: According to the most recent conceptual model, the continuity of services is increasingly recognized as a robust quality indicator. However, while many authors estimate that clinical files are, in principle, good observatories of continuity; very few have studied continuity from the files’ viewpoint. Theory: Global continuity comprises three dimensions, i.e., informational continuity, ...

a characteriation of continuity of the $p$-$lambda$-variation function is given and the helly's selection principle for $lambda bv^{(p)}$ functions is established. a characterization of the inclusion of waterman-shiba classes into classes of functions with given integral modulus of continuity is given. a useful estimate on modulus of variation of functions of class $lambda bv^{(p)}$ is found.
