Improving empowerment, motivation, and medical adherence in patients with poorly controlled type 2 diabetes: A randomized controlled trial of a patient-centered intervention.

OBJECTIVE

To test whether an intervention consisting of four patient-centered consultations improves glycemic control and self-management skills in patients with poorly regulated type 2 diabetes (T2DM), compared to a control group receiving usual care.

METHODS

Unblinded parallel randomized controlled trial including 97 adults diagnosed with T2DM ≥ 1 year and hemoglobin A1c (HbA1c) levels ≥ 8.0% (64 mmol/mol). Consultations incorporated tools supporting self-reflection, learning processes, and goal setting. Primary outcome was HbA1c. Secondary outcomes were autonomy support, motivation, self-management skills, and well-being.

RESULTS

Average HbA1c decreased slightly in both groups. Autonomy support and frequency of healthy eating were significantly higher in the intervention group. Most participants in the intervention group chose to set goals related to diet and physical exercise. Implementation of the intervention was inconsistent.

CONCLUSION

Despite increased autonomy support and individual goal-setting, the intervention was not superior to usual care in terms of glycemic control. More research is needed on how individual preferences and goals can be supported in practice to achieve sustainable behavior changes.

PRACTICE IMPLICATIONS

The intervention promoted participant engagement and supported exploration of participants' challenges and preferences. Further exploration of more flexible use of tools adapted to individual contexts is recommended.
