Variation in Transfusion Practices and the Association with Perioperative Adverse Events in Patients Undergoing Open Abdominal Aortic Aneurysm Repair and Lower Extremity Arterial Bypass in the Vascular Quality Initiative.

BACKGROUND: Blood transfusions are associated with adverse events. We examined perioperative transfusion practices and associated complications following open vascular procedures nationwide in the Vascular Quality Initiative (VQI). METHODS: Adults undergoing open abdominal aortic aneurysm repair (OAR) and lower extremity arterial bypass (Bypass) within VQI (2003-2016) were identified. All emergent cases, patients with preoperative hemoglobin <7 g/dL, preoperative hospitalization >1 day, or a return to operating room during the index hospitalization were excluded. Units of red blood cells transfused were the primary outcome. Secondary outcomes were postoperative myocardial infarction (MI) and death. Patient, center, and procedural factors were evaluated. Multivariable mixed effects negative binomial regression and multivariable logistic regression were performed. RESULTS: We identified 24,131 procedures (OAR 3885, 16.1%; Bypass 20,246, 83.9%) among 22,532 patients (10.1% had >1 procedure). Overall, 37.5% of OAR and 19.5% of Bypass were transfused. Transfusion rates varied across estimated blood loss quartiles and across various preoperative hemoglobin levels. The overall rate of postoperative MI and death was 4.0% and 1.8% for OAR, and 2.2% and 0.7% for Bypass, respectively. In univariate and multivariable analysis, transfusions were associated with an increased risk of postoperative MI and death. A mixed effects negative binomial model demonstrated variation in transfusions across centers (P < 0.001). Female gender and preoperative anemia were significantly associated with transfusions. CONCLUSIONS: Blood transfusions are variable across centers in VQI. Transfusions are associated with a higher postoperative MI and death after OAR and Bypass. Efforts to reduce transfusion may focus on center variability, gender, and preoperative anemia.

Obesity in trauma: outcomes and disposition trends.

BACKGROUND: Obesity's effect on the outcomes of trauma patients remains inconclusive. METHODS: A retrospective review of all falls, motor vehicle collisions (MVCs), and penetrating trauma patients admitted from January 2008 to December 2012 was performed. The outcomes evaluated included mortality, length of stay at hospital, and discharge disposition. Patients were grouped according to the body mass index (BMI) and stratified by injury severity scores. RESULTS: Two thousand one hundred ninety six patients were analyzed; 132 penetrating, 913 falls, and 1,151 MVCs. Penetrating traumas had no significant difference in outcomes. In falls, obese patients had a lower mortality (P = .035). In MVCs, obese patients had longer hospitalizations (P = .02), and mild and moderate MVC injuries were less likely to be discharged home (P = .032 and .003). Obese patients sustained fewer head injuries in falls and MVCs (P = .005 and .043, respectively). CONCLUSIONS: In falls, a higher BMI may benefit patients. However, an increasing BMI is associated with a longer length of stay at hospital, and decreased likelihood of discharge to home.

Surgical pulmonary embolectomy in a community hospital.

BACKGROUND: Surgical pulmonary embolectomy (SPE) is indicated for a pulmonary embolism associated with hemodynamic instability. A review of the literature demonstrates that most studies of SPE are conducted at large academic medical centers. This series is from a 325-bed community hospital. METHODS: A retrospective chart review was performed of patients undergoing SPE from January 2008 to December 2012. All patients aged >18 years were reviewed for 30-day mortality, length of hospital stay, comorbidities, and preoperative hemodynamic parameters. RESULTS: Fifteen patients (7 men and 8 women; median age, 55.5 years; range, 20-72 years) underwent SPE. There were 2 deaths (13.3%). Four of the patients underwent catheter-directed interventions before SPE. The mean length of hospital stay was 12 days. CONCLUSIONS: These data suggest that SPE is associated with favorable outcomes in the appropriate community setting, and the mortality rate seen in this study compares favorably with the nationwide average of 27.2%.
