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 (BP) control. 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for monitoring BP measurements and medication intake under nurse guidance for three months after which intervention was withdrawn.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. Trial registration: NCT02568137. Registered on 13 July 2015 at ClinicalTrials.gov.
