Allogeneic and autologous transplantation for haematological diseases, solid tumours and immune disorders. Current practice in Europe in 1996 and proposals for an operational classification. Accreditation Sub-Committee of the European Group for Blood and Marrow Transplantation (EBMT).

The indications and techniques employed for haematopoietic stem cell transplants performed in Europe differ substantially. The Accreditation Sub-Committee of the EBMT has consulted widely and has attempted to describe practice in Europe current in 1996 and in particular to define whether a particular procedure should be regarded as 'Routine' or whether it should be carried out preferably in the context of a Clinical Research Protocol or as part of a 'Developmental' pilot study. It is recognised that a classification of this kind must be imperfect and will require revision at frequent intervals.
