|Abstract: ||Background: The potential of mobile-health (mHealth) technology for the management of hypertension among stroke
survivors in Africa remains unexplored. We assessed whether an mHealth technology-enabled, nurse-guided intervention
initiated among stroke patients within one month of symptom onset is effective in improving their blood pressure
Methods: A two-arm pilot cluster randomized controlled trial involving 60 stroke survivors, 18 years, with BP 140/
90mmHg at screening/enrollment visit at a medical center in Ghana. Participants in the intervention arm (n¼30)
received a Blue-toothed BP device and smartphone with an App for monitoring BP measurements and medication
intake under nurse guidance for three months after which intervention was withdrawn. Control arm (n¼30) received
usual care. Primary outcome measure was proportion with clinic BP<140/90mmHg at month 9; secondary outcomes
included medication adherence.
Findings: Mean SD age was 55 13 years, 65% males. Two participants on intervention and three in control group
were lost to follow-up. At month 9, proportion on the intervention versus controls with BP<140/90mmHg was 14/30
(46.7%) versus 12/30 (40.0%), p¼0.79 by intention-to-treat; systolic BP<140mmHg was 22/30 (73.3%) versus 13/30
(43.3%), p¼0.035. Mean SD medication possession ratio was 0.95 0.16 on intervention versus 0.98 0.24 in the
control arm, p¼0.56.
Interpretation: We demonstrate feasibility and signal of improvement in BP control among stroke survivors in a
resource-limited setting via an mHealth intervention. Larger scale studies are warranted.
