Conference Keynote Speakers
Dr. Sikhululiwe Ngwenya
Chief Medical Officer, Virtual Hospital Africa
Keynote Topic: Reimagining Care in Africa: The development and validation of Virtual Hospitals Africa, a digital health platform using structured health data for transformed health services at all levels of care
Abstract: Digital health technologies are reshaping care delivery, yet systemic gaps persist in accessibility, coordination, and outcomes—particularly across Africa. Virtual Hospitals Africa is a co-designed, data-driven digital health platform that integrates patients, providers, and systems to enhance triage, referrals, and collaborative care. It supports learning health systems, real-time evidence generation, and continuous service improvement. By building a Consortium of innovative practitioners, we aim to overcome infrastructure, policy, and socio-cultural barriers while advancing education, equity, and economic sustainability. We recognize that technology alone is insufficient without inclusive design, professional capacity-building, and cultural relevance. This initiative reimagines care by combining connected platforms, artificial intelligence, structured data, and human-centered innovation to strengthen healthcare delivery at all levels.
