The Lancet Commissions document examines the state of health professional education and calls for reforms to better prepare graduates for 21st century health challenges. It finds that while advances in the 20th century doubled life expectancy, inequities persist globally and new health threats have emerged. Professional education has not adapted to these changing needs, with fragmented and outdated curricula producing ill-equipped graduates. The commissions proposes a vision of transformative, interdependent education to develop competent professionals who can address patient and population needs through collaborative team-based systems. It recommends instructional reforms like competency-driven learning and institutional reforms such as expanding academic systems and global networking to strengthen health systems worldwide.
