N2 - Background Blood transfusion has been shown to be associated with adverse long-term and short-term outcomes. We sought to evaluate the preoperative risk factors associated with blood transfusion and its effects on postoperative outcomes after adrenalectomy. Methods We performed a retrospective analysis of 4735 adrenalectomies (3664 laparoscopic and 1071 open) from 2005-2012 using the National Surgical Quality Improvement Program database. Data on preoperative risk factors and postoperative morbidity and mortality were evaluated. Results Median age and body mass index were 54 y and 29.3 kg/m2, respectively. Most patients were female (60.0%). Of the total, 60.6% patients had American Society of Anesthesiologists score ≥3. On multivariate analysis, increasing age (odds ratio [OR] = 1.02, P < 0.001), open adrenalectomy (OR = 14.0, P < 0.001), preoperative hematocrit <38% (OR = 2.96, P < 0.001), and operative time >150 min (OR: 3.69, P < 0.001) were associated with an increased need for intraoperative blood transfusions. The need for intraoperative blood transfusions was an independent predictor of postoperative complications including mortality (OR = 12.7, P < 0.001), overall morbidity (OR = 3.2, P < 0.001), serious morbidity (OR = 3.8, P < 0.001), wound complication (OR = 2.1, P = 0.006), cardiopulmonary complication (OR = 3.6, P < 0.001), septic complication (OR = 2.5, P = 0.007), reoperation (OR = 3.6, P < 0.001), and prolonged length of stay (OR = 4.3, P < 0.001). There was an independent and incremental increase (10%-20%) in the risk of morbidity and mortality with each unit of blood transfused (P < 0.01). Conclusions Age, open surgery, preoperative anemia, American Society of Anesthesiologists score, and prolonged operative time are associated with an increased need for blood transfusions in laparoscopic and open adrenalectomy.
