ABUJA – IN a bid to take the nation’s healthcare services to an enviable height, Nigeria’s first cardiologist and nephrology professor, Prof. Olurotimi John Badero, has pushed for stronger healthcare capacity, innovation, and training to equip healthcare professionals in the health sector.

Prof Badero who is a U.S.-based physician and the world’s first and only board-certified interventional cardio-nephrologist, said advancing Nigeria’s healthcare capacity through sustained clinical innovation, academic engagement, and mentorship—serves as a viable model for reversing talent loss in the country’s medical sector.

He said: “Reversing brain drain is not just about bringing people back, it is about creating systems where knowledge flows consistently into local institutions.

“When global expertise is intentionally applied within Nigeria, we begin to see real, measurable change.”

Based on his work, he has been marked by a series of groundbreaking medical milestones in Nigeria, including performing the country’s first selective renal angiogram as well as the first endovascular limb salvage revascularization for critical limb ischemia with occluded arteries in PAD patients.

He has also contributed to the discovery and publication of several first-of-their-kind cardiovascular cases in Nigeria, including the first coronary cameral fistula in Nigeria, which helped elevate both clinical practice and medical research standards.

These achievements represent more than individual accomplishments; they signal a growing capacity within Nigeria’s health system to deliver advanced, globally competitive care.

In 2025, Prof. Badero was appointed Distinguished Fellow and Visiting Professor of Medicine at the University of Lagos, where he contributes to mentoring resident doctors and training consultant cardiologists alike, fostering research collaborations, and supporting the alignment of medical training and research with international standards.

Meanwhile, he asserted that broader opportunity for Nigeria includes; the strategic engagement of diaspora medical professionals as a pathway to addressing longstanding capacity gaps in specialized healthcare.

He added that by combining international training with local application, such collaborations can accelerate innovation, improve outcomes, and reduce dependence on outbound medical tourism.

Stakeholders also emphasized that scaling this model will require deliberate efforts including stronger institutional partnerships, enabling policy frameworks, and incentives that encourage diaspora professionals to contribute to national development.

Prof. Badero who hails from Isonyin, and honoured as the first Professor of Medicine from Isonyin, Ogun State, said his ongoing work demonstrates what is possible when global expertise is intentionally reinvested locally, not as a one-time return, but as a continuous exchange of knowledge, skill, and commitment.

Also, for his outstanding medical career and service to humanity in 2016, bringing unique and invaluable expertise to the University of Lagos as Africa’s first Professor of Cardiology and Nephrology, he was honored by the United States House of Representatives.

His distinguished clinical and academic contributions exemplify the impact of diaspora engagement through sustained collaboration, knowledge transfer, and strengthening of the healthcare system.
