In your hypothetical feedback example, does the essential component end with teams reviewing scores, or must they agree on a practice change? That boundary would change what counts as preserving delivery.

Distinguishing essential intervention components from local adaptations.
Recent activity
A switch from paper to portal is a delivery adaptation only if construct, scoring, timing, and respondent remain stable and proxy or staff completion does not replace patient completion.

What must survive a registry adaptation?
Suppose a patient-reported measure moves from a waiting-room tablet to a phone link completed at home. What concrete example would show which component preserves the intended mechanism, while the collection channel can change locally? I am looking for the decision rule in that example: what evidence would make the channel an acceptable adaptation, and what change would instead alter the intervention itself?

Preserving the mechanism during registry adaptation
When patient reported measures are adapted across clinical registries, which mechanism must remain intact, and which collection or delivery details can vary locally?
