About Ghislaine
Ghislaine Zinzindohoue is Co-Founder of Ayooka, the first fully integrated digital system for blood transfusion management in Guinea. Built in Africa, for Africa, Ayooka addresses one of the most critical gaps in the continent's health infrastructure: a blood supply chain that is reactive, fragmented and frequently unable to meet demand. Ghislaine's approach is to shift that system from crisis response to prediction, using AI to amplify health professionals rather than replace them.
The focus of her work
Ayooka digitises the entire blood supply chain, from donor to patient, enabling real-time monitoring of stock levels, predictive analytics to anticipate shortages, and full coordination with the National Blood Transfusion Center. AI automatically analyses stock levels across facilities, detects early signs of shortage, and triggers preventive alerts. Predictive models integrate historical trends, seasonal patterns and hospital consumption data to forecast demand and optimise collection, storage and distribution. Every clinical and operational decision remains human-led.
Impact
Over 156,000 blood units processed annually, covering Guinea's estimated national needs
18 to 25 percent reduction in stock-out risks through real-time AI monitoring and early alerts
Up to 30 percent decrease in blood product wastage through optimised allocation
Improved patient safety through reduced human error and strengthened transfusion traceability
Stronger coordination across hospitals, laboratories and the National Blood Transfusion Center
Responsible AI in practice
Ayooka operates in a sector where errors cost lives, and responsible AI is built into its architecture accordingly. Data is end-to-end encrypted, anonymised and access-controlled, with no data shared without institutional approval. Predictive models are documented, tested and regularly audited, with explainable outputs and human validation for critical decisions. The system was co-designed with doctors, technicians, managers and the National Blood Transfusion Center to ensure it is contextually relevant, culturally aligned and trusted by the people using it.
Vision for the future
AI built in Africa, for Africa, that is innovative, responsible and deeply human. Ayooka as a catalyst for a new generation of ethical health technologies across the continent, demonstrating that local realities and global standards are not in tension.
