OBJECTIVE The heterogeneity of specialist palliative care services requires a classification to enable a clear description and comparison. In Germany, specialist palliative care is provided by palliative care units, palliative care advisory teams in hospitals and palliative home care teams. The differentiation between the three care settings can serve as a first level of classification. However, due to profound variations in regulatory structures and financing systems, services within each setting are heterogeneous and characteristics remain unclear, which impedes quality management. Further characteristics of specialist palliative care models need to be considered to allow for differentiation. Thus, services should be described on a polyhierarchical basis, such as a typology, representing relevant characteristics. We aimed at the development of a comprehensive classification to facilitate the description and differentiation of specialist palliative care models. METHODS Qualitative study including the development of a literature based, preliminary list of structural and processual characteristics, expert interviews and focus groups. Eleven interviews from May to June 2020 and two focus groups, with seven and nine participants each, in January 2021. RESULTS Several structure and process characteristics were identified as suitable features for the specification of specialist palliative care in Germany. A classification in form of a typology including relevant characteristics has been developed. CONCLUSIONS The advanced typology refines the existing level of differentiation within specialist palliative care services in Germany and paves the way for an improved understanding of services. This deeper insight into structure and process characteristics of specialist palliative care is necessary internationally.
