Prospective evaluation of patient adherence to peer-grounded paths

Determine through a prospective study whether presenting patients with a peer-grounded behavioral path causes them to attempt more of the recommended sequence than presenting them with a single behavioral prescription.

Background

POROS generates multi-step behavioral recommendations by routing through observed peer states that are behaviorally close and associated with strictly improved health outcomes. The retrospective evaluation demonstrates that these paths reduce the behavioral and glycemic change required at each step, but it does not establish whether patients would actually follow more of such a sequence than a conventional single-step recommendation.

The unresolved issue is therefore behavioral and prospective: patient engagement and adherence to peer-grounded paths must be tested in an intervention study rather than inferred from retrospective cohort data.

Whether patients presented with a peer-grounded path attempt more of it than a single prescription is a question only a prospective study can answer.
