The most comprehensive analysis of hypertension data across Ghana, synthesizing findings from multiple population studies. Establishes that approximately one in three Ghanaian adults has hypertension, while only 22% receive treatment and just 6% achieve blood pressure control. These figures define the treatment gap that GHSI addresses.

Documents cardiovascular disease as the number one cause of death in Ghana, with hypertension as the primary modifiable risk factor. Reinforces the urgency of community-level screening programs that reach populations outside the formal healthcare system.

Nationally representative household survey providing demographic and health indicators across all regions. Supplies the population-level context for understanding hypertension within broader patterns of healthcare access, urbanization, and socioeconomic status in Ghana.

Large-scale screening campaign in the Ashanti Region demonstrating the feasibility of community-based blood pressure measurement in Ghana. Findings revealed significant undiagnosed hypertension in working-age populations, supporting the case for mobile screening at sites where people gather for work.

Establishes the direct link between uncontrolled hypertension and stroke in the Ghanaian population. Hypertension is the strongest modifiable risk factor for stroke in sub-Saharan Africa, making blood pressure control the single most impactful preventive intervention available.

The foundational trial establishing the PALS methodology. Demonstrated that peer-delivered health education using Reusable Knowledge Objects (RKOs) and Adult Learning Theory can produce measurable improvements in health literacy and patient activation. Participants showed significant gains in understanding their conditions and engaging with care.

Large-scale implementation trial demonstrating that the PALS-based peer education approach can achieve population-level impact. Achieved a 5 mmHg average blood pressure reduction across diverse community settings. This magnitude of reduction, applied at population scale, is associated with significant decreases in stroke and cardiovascular mortality.

Evaluates a Training of Trainers curriculum for religious leaders delivering hypertension education in communities with limited healthcare access. Conducted through the Cornell-Weill-Bugando collaboration in Tanzania. Demonstrated that non-medical community leaders can be effectively trained to deliver accurate, culturally appropriate health education using structured materials.

Feature article describing the Cornell and Weill Cornell Medicine research collaboration training religious leaders to address hypertension in their communities. Documents the real-world application of the Training of Trainers model and its potential for replication across sub-Saharan Africa.

The BE-FAST mnemonic (Balance, Eyes, Face, Arms, Speech, Time) is an expanded stroke recognition tool validated for public health education. Studies demonstrate improved stroke recognition and faster emergency response when community members are trained in structured recognition protocols.

The WHO's integrated framework for cardiovascular disease management in primary healthcare. HEARTS provides standardized protocols for Healthy lifestyle counselling, Evidence-based treatment protocols, Access to essential medicines, Risk-based management, Team-based care, and Systems for monitoring. Designed specifically for low- and middle-income country implementation.

Results from the global May Measurement Month campaign at Ghanaian screening sites. Demonstrates the feasibility and yield of large-scale community blood pressure measurement events in Ghana, providing operational lessons for event-based screening logistics, volunteer coordination, and immediate result communication.

Simple is an open-source, offline-first mobile application designed for community health workers to record blood pressure measurements, track patients over time, and generate population-level dashboards. Deployed across India, Bangladesh, Ethiopia, Sri Lanka, and Nigeria, Simple currently supports the management of over 6 million patients. Its design prioritizes speed, simplicity, and reliable performance without consistent internet connectivity.

Proceedings from a multi-stakeholder roundtable convening the World Heart Federation, Ghana Society of Cardiology, and SASNET-Ghana to assess the state of cardiovascular disease prevention in Ghana. Discusses the current policy landscape, community health worker capacity, and integration of screening programs into existing health infrastructure.

MedExplain Health is a nonprofit health literacy platform that creates evidence-based, accessible medical information using the Patient Activated Learning System (PALS) methodology. PALS content is designed to engage marginalized communities and individuals with low health literacy through Reusable Knowledge Objects (RKOs), storytelling, and adult learning theory. The platform has reached visitors in over 200 countries.

A prospective cohort study tracking blood pressure changes among Ghanaians over time. Builds on the original RODAM (Research on Obesity and Diabetes among African Migrants) study by adding longitudinal follow-up. Provides evidence on how blood pressure evolves in Ghanaian populations and the modifiable factors associated with worsening or improving trajectories.
