Using language nudges and a medication-preference app to boost shared decision-making and self-care in type 2 diabetes

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized trial 250 adults with type 2 diabetes at Xiang'an Hospital will be assigned to an intervention or usual-care group and followed for six months. Clinicians in the intervention arm receive training in linguistic nudging to encourage shared decision-making, while patients use a mobile app to record medication preferences that clinicians can view and incorporate. The control group receives standard diabetes care without the training or preference app. Primary outcomes include medication adherence, frequency of blood glucose monitoring, and measures of glycemic control.
