In the Netherlands self-management for chronic disease patients has been adopted in routine care in both primary and secondary care. Evidence suggests high variance in succes of self-managment exposure. In our quest to unravel success of this therapeutic stimulus, in a prospective cohort study we aim at assessing both patient- and intervention- specific effect modifiers of success of self-management. To assess patient-profiles and direction and size of effectiveness will not be much of a problem. Otherwise, assessing both content, mode and intensity (dose) of routine care self-management exposure is a larger issue. Do you have any suggestions how we can screen/measure this hybrid type of exposure ? What is your opinion on providers (mostly nurses) self-reporting content/mode/dose of their own consultations in our longitudinal cohort study ?
