Abstract Introduction Patients requiring prolonged acute mechanical ventilation PAMV represent one-third of those who need mechanical ventilation but they utilize two-thirds of hospital resources devoted to mechanical ventilation. Measures are needed to optimize the efficiency of care in this population. Both duration of intensive care unit stay and mechanical ventilation are associated with anemia and increased rates of packed red blood cell pRBC transfusion. We hypothesized that transfusions among patients receiving PAMV are common and associated with worsened clinical and economic outcomes. Methods A retrospective analysis of a large integrated claims database covering a 5-year period January 2000 to December 2005 was .
