The effect of nurse‐led telephone support on adherence to blood pressure control and drug treatment in individuals with primary hypertension: A randomized controlled study

AIM: The aim of this study was to evaluate the effect of telephone monitoring, in combination with texts, on medication adherence and blood pressure (BP) control in primary hypertension. METHOD: Data were collected from August to December 2016. Seventy-seven adults were randomized to the intervention and control groups. A 12-week intervention consisted of regular text messages and phone calls. The control group received usual hypertension care. The outcomes were evaluated with blood pressure measurement and medication adherence self-efficacy scale short form. RESULTS: Medication adherence in Week 12 was found to be significantly higher in the intervention group than in the control group. Mean systolic and diastolic BP levels in Weeks 4, 8 and 12 were statistically significantly lower in the intervention group than in the control group (p < 0.05). CONCLUSION: Using text messaging and nurse-led telephone monitoring improved adherence and BP control in adults with hypertensive in primary care.
