Abstract:
Patient empowerment through pharmacological self-management is a common strategy in some chronic diseases such as diabetes, but it is rarely used for controlling blood pressure. Objective This study aimed to assess self-monitoring plus self-titration of antihypertensive medication versus usual care for reducing systolic blood pressure (SBP) at 12 months in poorly controlled hypertensive patients. Design The ADAMPA study was a pragmatic, controlled, randomized, non-masked clinical trial with two parallel arms in Valencia, Spain. Participants Hypertensive patients older than 40 years, with SBP over 145 mmHg and/or diastolic blood pressure (DBP) over 90 mmHg, were recruited from July 2017 to June 2018. Intervention Participants were randomized 1:1 to usual care versus an individualized, pre-arranged plan based on self-monitoring plus self-titration. Main Measure The primary outcome was the adjusted mean difference (AMD) in SBP between groups at 12 months. Key Results Primary outcome data were available for 312 patients (intervention n =156, control n =156) of the 366 who were initially recruited. The AMD in SBP at 12 months (main analysis) was −2.9 mmHg (95% CI, −5.9 to 0.1, p =0.061), while the AMD in DBP was −1.9 mmHg (95% CI, −3.7 to 0.0, p =0.052). The results of the subgroup analysis were consistent with these for the main outcome measures. More patients in the intervention group achieved good blood pressure control ( 〈 140/90 mmHg) at 12 months than in the control group (55.8% vs 42.3%, difference 13.5%, 95% CI, 2.5 to 24.5%, p =0.017). At 12 months, no differences were observed in behavior, quality of life, use of health services, or adverse events. Conclusion Self-monitoring plus self-titration of antihypertensive medication based on an individualized pre-arranged plan used in primary care may be a promising strategy for reducing blood pressure at 12 months compared to usual care, without increasing healthcare utilization or adverse events.
