A new integrated care organization (Hälsostaden) was established to merge primary and hospital care with elderly and social care. Hälsostaden is jointly managed by its regional and municipal government and employs 600 professionals across health and social sectors; early investments in stakeholder relationships and trust building were essential for securing the future of the initiative and developing a foundation based on teamwork; finding the uniting objective of improving care for elderly people enabled stakeholders to move forward with planning; contextualizing the initiative within emerging political priorities helped generate political support and secure the necessary legal frameworks; identifying individual organizational strengths and pooling resources minimized required investments and supported in-house initiatives.
