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

Effect of Nudge-Based Shared Decision Making on Self-Management Among Patients With Type 2 Diabetes: A Randomized Controlled Trial

NA · Xiamen University · NCT07129915

This trial will test whether training doctors to use short language 'nudges' plus a mobile app for recording medication preferences helps adults with type 2 diabetes make treatment choices and stick to their medicines.

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.

Who should consider this trial

Good fit: Adults aged 18 or older with confirmed type 2 diabetes, normal cognitive function, basic smartphone/WeChat ability, and willingness to give informed consent are ideal candidates.

Not a fit: Patients with severe acute diabetic complications, documented cognitive impairment, inability to use a smartphone/WeChat, current participation in other trials, pregnancy/lactation, or life expectancy under six months are unlikely to benefit from this program.

Why it matters

Potential benefit: If successful, the approach could improve medication adherence, increase glucose self-monitoring, and lead to better blood sugar control by aligning clinician advice with patient preferences.

How similar studies have performed: Previous studies combining clinician communication techniques and mobile preference tools have shown modest gains in adherence and decision quality, but results are mixed and data specific to Chinese T2D populations are limited.
