IntroductionTalking about existential issues with patients is often experienced as challenging for healthcare professionals. This paper describes our first steps towards developing existential communication training with particular attention to reflective learning methods. Blended learning was chosen to support reflection and an easier transition to classroom conversations, and through Participatory Action Research (PAR), patients were involved in developing the curriculum.MethodTo develop the most valuable and relevant communication training, patients, relatives, healthcare professionals and researchers were involved in a PAR process including 1) three theatre workshops and 2) collaborative meetings to develop the blended learning curriculum and reflection videos. The evaluation of the communication training was based on semi-structured interviews with the healthcare professionals participating in the blended learning communication training.Discussion and innovationThe results indicate that a blended learning format involving a high degree of reflection is valuable for developing skills related to existential communication. Engaging patients in the process may be essential to develop a training curriculum for healthcare professionals that accommodates the patient's needs.ConclusionFuture communication training on existential communication may benefit from adopting a blended learning format, including reflective learning methods and the involvement of patients in curriculum development.
