The COVID-19 pandemic was arguably the greatest disrupter health professional education (HPE) has ever experienced. To explore how lessons learned from this unprecedented event could inform the future of HPE, the Global Forum on Innovation in Health Professional Education of the National Academies of Sciences, Engineering, and Medicine convened a virtual workshop series in 2020 and 2021. The first workshop focused on identifying challenges faced by educators, administrators, and students amidst the pandemic and how the different stakeholder groups shifted and adapted in response. The second workshop explored how experts from various health professions might respond to hypothetical--but realistic--future world situations impacting HPE. The final two workshops contemplated the future of HPE post-COVID and explored next steps for applying lessons learned from the workshop series to allow educators to test and evaluate educational innovations in real time. This Proceedings of a Workshop summarizes discussions from the second, third, and fourth workshops in this series.
