Hypertension is the premier modifiable risk factor for recurrent stroke. In sub-Saharan Africa (SSA) where the stroke burden is escalating, little is known about the role of behavioral interventions in enhancing blood pressure (BP) control after stroke. Our objective is to test whether an m-Health technology-enabled, nurse-led, multilevel integrated approach is effective in improving BP control among Ghanaian stroke patients within 1 month of symptom onset compared with standard of care.
This two-arm cluster randomized controlled feasibility pilot trial will involve 60 recent-stroke survivors. Using a computer-generated sequence, patients will be randomly allocated into four clusters of 15 patients each per physician: two clusters in the intervention arm and two in the control arm. Patients in the intervention arm will receive a simple pillbox, a Blue-toothed UA-767Plus BT BP device and smartphone for monitoring and reporting BP measurements and medication intake under nurse guidance for 3 months. Tailored motivational text messages will be delivered based upon levels of adherence to the medication intake. Both groups will be followed up for 6 months to compare BP control at months 3, 6 and 9 as primary outcome measure. Physicians assessing BP control will be blinded to arms into which patients are allocated. Secondary outcome measures will include medication adherence scores and Competence and Autonomous Self-regulation Scale scores. A qualitative study is planned after follow-up to explore the lived experiences of participants in the intervention arm.
A feasible and preliminarily effective intervention would lead to a larger more definitive efficacy/effectiveness randomized controlled trial powered to look at clinical events, with the potential to reduce stroke-related morbidity and mortality in a low- to middle-income country.

高血压是复发性中风首要的可改变风险因素。在中风负担不断加重的撒哈拉以南非洲地区,对于行为干预在中风后强化血压控制方面的作用了解甚少。我们的目标是测试一种由护士主导、借助移动健康技术的多层次综合方法,与标准治疗相比,在症状出现后1个月内改善加纳中风患者血压控制的效果。
这项双臂整群随机对照可行性试点试验将纳入60名近期中风幸存者。使用计算机生成的序列,患者将被随机分配到每个医生负责的四个每组15名患者的整群中:干预组两个整群,对照组两个整群。干预组的患者将获得一个简易药盒、一台蓝牙UA - 767Plus BT血压设备和一部智能手机,以便在护士指导下监测和报告血压测量值及药物摄入情况,为期3个月。将根据药物摄入的依从程度发送量身定制的激励短信。两组均随访6个月,以比较第3、6和9个月时的血压控制情况作为主要结局指标。评估血压控制情况的医生将对患者被分配到的组保持盲态。次要结局指标将包括药物依从性得分以及能力与自主自我调节量表得分。计划在随访后进行一项定性研究,以探索干预组参与者的生活经历。
一种可行且初步有效的干预措施将促成一项规模更大、更具确定性的疗效/效果随机对照试验,该试验有能力观察临床事件,有可能降低低收入和中等收入国家与中风相关的发病率和死亡率。
