Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overall objective of Phone-based Intervention under Nurse Guidance after Stroke II (PINGS-2) is to deploy a hybrid study design to firstly, demonstrate the efficacy of a theoretical-model-based, mHealth technology-centered, nurse-led, multi-level integrated approach to substantially improve longer term BP control among 500 recent stroke patients encountered at 10 hospitals in Ghana. Secondly, PINGS II seeks to develop an implementation strategy for routine integration and policy adoption of mhealth for post-stroke BP control in a LMIC setting. The investigators will leverage experience gained from the NIH Global Brain Disorders funded R21 pilot study (NS094033) to test efficacy of a refined, culturally-tailored, and potentially implementable intervention aimed at addressing the premier modifiable risk for stroke \& other key variables in an under-resourced system burdened by suboptimal care \& outcomes.

Study Groups

PINGS 2

Participants received a 12-month, multicomponent, nurse-led intervention in addition to usual post-stroke care. The intervention included:

Home blood pressure monitoring at least weekly with nurse follow-up for threshold breaches.

Mobile phone medication reminders (daily alarms set on the participant's own device).

Weekly audio health education messages in local dialects emphasizing stroke risk factor control and medication adherence.

Nurse navigators provided case management, coordinated clinic visits as needed, and tracked blood pressure readings and adherence.

Group Type EXPERIMENTAL

PINGS 2

Intervention Type BEHAVIORAL

Home BP monitoring, medication reminders using phone alerts, and patient education on hypertension, cardiovascular risk reduction \& stroke

Standard of Care

Participants received standard secondary prevention after stroke according to local guidelines. This typically included periodic physician follow-up, antihypertensive therapy, antiplatelets, and statins prescribed at the clinician's discretion.

To maintain contact frequency similar to the intervention group, participants received neutral lifestyle text messages unrelated to hypertension or stroke prevention.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* age ≥ 18 years (stroke is commoner above this age cut-off)
* male or females (sex is a biologic variable of interest)
* recent stroke (within one month of symptom onset)- stroke may be ischemic or hemorrhagic based on brain imaging or diagnosed clinically using the locally validated version of the 8-item questionnaire for verifying stroke free status (8-QVSFS) when neuroimaging is not feasible
* uncontrolled HTN (SBP ≥ 140 mmHg at both the last clinical encounter post-stroke and the eligibility screening visit) - SBP is used as the selection variable since most African hypertensives \<60 years have systolic or combination systolic/ diastolic HTN and for most patients, controlling SBP also results in DBP control
* patients or family carers should own a basic mobile phone that can receive text/audio messages.
