With the European population's increasing lifespan, the imperative of promoting healthy ageing comes to the forefront, necessitating enhanced healthcare, a skilled workforce, age-friendly environments, and a united effort against ageism across all sectors. WHO/Europe is set to host the Regional Summit for Policy Innovation on Healthy Ageing on October 10-11 in Lisbon, Portugal, in collaboration with the Directorate General of Health of Portugal. This summit will convene government representatives, thought leaders, policy experts, academics, civil society members, professional organizations, and partners to drive policy innovation and explore best practices for addressing the implications of ageing populations. A central goal of the summit is to assess the progress and process evaluation of the Decade of Healthy Ageing in the European Region while delving into policy innovations and promising practices in light of rapidly ageing demographics. Over the two days, participants will engage in technical discussions encompassing various critical themes, including creating supportive environments for healthy ageing, reshaping perspectives on ageing, person-centered community-based long-term care, equitable quality care, promoting active lifestyles and healthy diets, workforce considerations, data and monitoring frameworks for the UN Decade of Healthy Ageing, countering misconceptions hindering effective health financing policies for an ageing populace, and supporting and empowering informal caregivers, along with promoting health and digital literacy.
