Structured hypertension education program for people with type 2 diabetes, the SHED study

Abstract

Objectives

There is enough evidence that patient education and lifestyle modification has shown benefits in diabetes care, however the evidence is less for improving care of hypertension. Our study is the first in the UK to assess the impact of a structured hypertension education program in subjects with type 2 diabetes. Design: Prospective randomised controlled study. Setting and Intervention: From a diabetes clinic in a district and general hospital in UK 132 participants were equally randomised into intervention group and control group. Intervention included a once weekly education session for 4 weeks together with home blood pressure monitoring and dose changes in antihypertensives. Base line data was recorded with follow up after 3 and 6 months.

Results

More participants achieved target BP in the intervention group versus control. This difference appeared early at the 3rd months (48.8% versus 20.4% respectively, p = 0.007) and remained at the 6th month (58.1% versus 20.4% respectively, p < 0.001). The change in number of pills was significantly lower in the intervention group. The mean increase in antihypertensive pills was 0.22 ± 0.48 (13 ± 30% increase) in the intervention group versus 0.62 ± 0.68 (41 ± 60% increase) in the routine group (p = 0.014), denoting less need to escalate treatment.

Conclusion

We demonstrated that our structured education program has led to a significantly higher percentage of participants achieving the BP target, early after intervention, together with a significant reduction in the number of antihypertensive pills.
