Aim: The purpose of this study was to assess the efficacy of the Spanish Diabetes Self-Management Program (SDSMP) versus usual care in adults with type 2 diabetes mellitus (T2DM) residing in a Spanish region.
Methods: A two-year follow-up randomised controlled trial. The intervention consisted of 6 weekly structured peer-to-peer workshops. The primary outcome was change in HbA1c levels. Secondary outcomes included other clinical measures, quality of life, self-efficacy, life-style changes, medication and use of healthcare services. Mixed effect models were fitted.
Results: n=297 patients were recruited in each study arm. Baseline HbA1c levels were comparable in both groups with an overall mean 7.1 (SD=1.2). The intervention did not significantly modify HbA1c, or other cardiovascular variables. Significant improvements were seen in self-efficacy, and in particularly its disease control component. Certain differences were also observed in the use of healthcare resources and medication consumption. High workshop participation and satisfaction rates were achieved.
Conclusion: HbA1c reductions are difficult to obtain in adequately controlled patients. On the other hand, raising awareness on one's disease can increase disease control self-efficacy. This finding, accompanied by reduced medication consumption and healthcare use rates, highlights that usual care would be benefited by incorporating certain SDSMP aspects.
