The average hospital stay for stem cell transplant is 30 days. After discharge, patients will return for follow-up clinic visits weekly or twice weekly for 4 months. These visits will include a symptom check, physical examination, and blood tests. Blood transfusions will be given if needed. Subsequent visits will be scheduled at 4, 6, 12, 18, 24, 30 and 36 months after the transplant or more often if required, and then yearly.
