title: Survival of adult bone marrow transplant patients receiving mechanical ventilation: a case for restricted use.
abstract: A retrospective study of all adults receiving BMT over a 13 year period at a large transplant center was performed to determine overall survival and prognostic indicators of poor outcome among patients receiving mechanical ventilation (MV). Of 653 adult BMT patients, 191 (29%) received MV after transplant. Of these 191, 161 (84%) died on the ventilator or within hours of extubation; 18 (10%) survived 1 week after extubation and 6 (3%) survived 6 months. Survival was not predicted by type of graft, use of total body irradiation (TBI) or reason for intubation. The patient's age and the timing of intubation were predictive of survival. Of patients > or = 40 years, 98% died within a week of extubation and all died within 30 days. Similarly, of those intubated within 90 days of transplant, 94% died within a week of extubation and all died by day 100. These results suggest that MV is rarely effective in achieving long-term survival in adult BMT recipients, especially older patients and those early in their transplant course. An argument, based on cost/benefit considerations and medical futility, can be developed to withhold MV in certain patient subsets apart from a clinical research trial.
