The progressive loss of physical functioning resulting from ALS leads also to high psychosocial burden for those affected, and organizational challenges related to medical care and aids. A multidimensional and -professional care is advised in order to meet the complex requirements of this disease. In Germany, medical care structures may not fulfil these high requirements, since non-medical services such as psychological support or social counselling are not regularly included in care procedures for ALS patients. Specialised palliative care is not a standard and still commonly restricted to the last weeks of life. Additionally, it is well known that caregivers of ALS patients are highly burdened, but there is a lack of support services for them. By means of a cross-sectional, multicentre survey, we aim to investigate patients' and caregivers' perception of medical care for ALS, provided in Germany - with particular regard to psychosocial and palliative aspects. The extent to which physical, psychological, social, spiritual, practical and informational needs are subjectively met will be assessed and correlations with mental wellbeing, subjective quality of life, attitudes towards life-sustaining measures and physician-assisted suicide, as well as caregiver burden will be examined. Currently, study planning (questionnaires and ethical approval) is already completed and recruitment was started. The study aims to recruit 500 participants from nationwide ALS-centres. Cooperating ALS-centres will be recruited via the German Network for Motoneuron Diseases (MND-Net), of which our centre is a member. It is intended to provide data-based starting points on how care of ALS patients and their caregivers can be improved in Germany, in line with their needs.
