PURPOSE

The aim of this study is to prospectively evaluate whether individual and group Therapeutic Patient Education (TPE) can reduce the need to intensify treatment of diabetes and hypertension in newly diagnosed type 2 diabetic patients.

METHODS

A total of 937 patients were recruited and followed-up for 42.7 ± 21.5 months. TPE was a structured comprehensive education delivered by trained nurses: 322 patients received individual TPE (ITPE), 291 underwent group TPE (GTPE), and 324 were in Usual Care (UC). The primary endpoints were intensification of diabetes treatment and intensification of hypertension treatment.

RESULTS

The rate of diabetes treatment intensification was 40.1% in patients receiving ITPE, 47.8% in patients undergoing GTPE, and 64.2% in patients in UC (p < 0.001). The rate of hypertension treatment intensification was 24.2% in patients following ITPE, 31.3% in patients receiving GTPE, and 41.0% in patients in UC (p < 0.001). Multivariate analysis showed that both ITPE and GTPE were associated with reduced intensification of diabetes (ITPE: HR:0.51; 95% IC:0.40-0.64; p < 0.001 - GTPE: HR:0.46; 95% IC:0.44-0.70; p < 0.001) and hypertension medication (ITPE: HR:0.45; 95% IC:0.34-0.61; p < 0.001 - GTPE: HR:0.49; 95% IC:0.38-0.65; p < 0.001). The association was independent of age, sex, BMI, HbA1c, and presence of hypertension at baseline.

CONCLUSIONS

TPE, delivered as both individual and group sessions, represents an effective tool to reduce the need to intensify treatment of both diabetes and hypertension. Therefore, it can ensure better control of diabetes and hypertension with fewer medications. This could reduce adverse effects and costs and improve quality of life and medication taking in patients with type 2 diabetes.
