The Josep Carreras Foundation has always had among its objectives to help accelerate the introduction of the most advanced therapeutic methods in health centers and improve research infrastructures. For this reason and within its capabilities, the Foundation has provided support to accredited, publicly accessible centres in order that patients and service teams are able to benefit from the best possible conditions.

The support provided in 1989 for the creation of the intensive haematologic treatment unit at the Hospital Clínic in Barcelona was one of the first great outcomes of this goal. This was the centre in which José Carreras stayed throughout his treatment and by providing its support, the Foundation wished to ensure that patients also had the best possible conditions of asepsis required for transplants.

Similarly, the Foundation also made a highly significant contribution to the creation of the transplant unit at the Hospital Universitari Germans Trias i Pujol in 1998.

Other Spanish centres that have received support are the Hospital del Mar and the Hospital Duran y Reynals in Barcelona, the Regional Transfusion Centre in Madrid, the Hospital Vall d'Hebron Foundation for Biomedical Research, the Umbilical Cord Blood Bank in Malaga, The Transfusion Centre in Alicante, and the Neonatal Study Group in Barakaldo, Basque Country. Such support is generally directed towards improving the infrastructure of research programmes and improving both the quality and efficiency of the categorization of blood samples gathered in the process of registering donors on the REDMO.

Occasionally, and with the aim of supporting events and concerts beneficial for raising awareness about leukaemia, the Foundation and its president has lent support to countries whose health systems still suffer great shortages. Health and Community Centres which have received such support include: the Croatian Lymphoma and Leukaemia Foundation, the Department of Oncology at the Zagreb Childrens' Hospital, the University Medical Center in Ljubljana, and the Paediatric Department at the University of Medicine in Budapest.
