Characteristics and outcome of patients presenting to the emergency department after autologous/allogeneic stem cell transplantation.

Introduction: Hematopoietic stem cell transplantations are still associated with a high risk of complications. Here, we characterize patients after autologous or allogeneic transplantation presenting to the emergency department and investigate factors associated with patients' outcome after hospitalization. Methods: Patients who had previously undergone autologous or allogeneic stem cell transplantation were included in this study and data were collected retrospectively. We analyzed patients' characteristics and outcome, and identified factors associated with outcome. Results: A total of 35% of presenting autologous and 52% of allogeneic patients were hospitalized for more than 7 days. In-hospital mortality was 4% (autologous) and 11% (allogeneic patients). In patients with a history of autologous transplantation, multivariate analysis indicated radiologic signs of pneumonia as an independent factor associated with the endpoint 'hospitalization of more than 7 days' (P
