After the initial monitoring period during hospitalization and isolation, patients with recent transplants are regularly monitored in monthly consultations but are still fragile, immunosuppressed and undergoing many treatments. The implementation of an outpatient assistance program for transplant patients should be feasible and allow for the improvement in medical-psycho-social care for the patients during this fragile and risky period, improve the satisfaction and quality of life for these transplant patients and assist in their socio-professional and familial reintegration.

• Having received an allogeneic hematopoietic stem-cell transplant
• In full remission
• Outpatients
