Clinical Trial
Fondaparinux for prevention of venous thromboembolism in high-risk trauma patients: a pilot study.
Venous thromboembolic events (VTE) remain a major cause of morbidity and mortality after trauma. Fondaparinux, a synthetic, nonheparin drug, has shown promise in reducing VTE in orthopaedic patients, but has not previously been studied in trauma patients. The goal of this study was to determine the safety and efficacy of fondaparinux when incorporated into our VTE prevention protocol. We hypothesized that the occult deep vein thrombosis (DVT) rate in high-risk patients receiving fondaparinux would be <5%. ⋯ Fondaparinux appears to offer protection against VTE in high-risk trauma patients. Its once-daily dosing regimen can improve compliance and reduce cost and eliminate risk of heparin-induced thrombocytopenia.

Like most trauma registries, the National Trauma Data Bank (NTDB) is limited by the problem of missing physiologic data. Multiple imputation (MI) has been proposed to simulate missing Glasgow Coma Scale (GCS) scores, respiratory rate (RR), and systolic blood pressure (SBP). The aim of this study was to develop an MI model for missing physiologic data in the NTDB and to provide guidelines for its implementation. ⋯ This article proposes an MI model for imputing missing physiologic data in the NTDB and provides guidelines to facilitate its use. Implementation of the model should improve the quality of research involving the NTDB. The methodology can also be adapted to other trauma registries.

Protecting future childbearing motivates young women with breast cancer to seek oocyte or embryo cryopreservation. Concerns about delays in cancer treatment may influence patients and practitioners considering these procedures. In this study, we compared timing of chemotherapy in women who underwent ovarian stimulation/oocyte retrieval (OR) and embryo cryopreservation with those who did not. ⋯ Fertility preservation is an important component of quality of life for young women with breast cancer. The time investment required for OR and cryopreservation is manageable and does not significantly prolong the time interval from diagnosis to start of adjuvant chemotherapy.

Comparative Study
Predicted risk of mortality models: surgeons need to understand limitations of the University HealthSystem Consortium models.
The University HealthSystem Consortium (UHC) mortality risk adjustment models are increasingly being used as benchmarks for quality assessment. But these administrative database models may include postoperative complications in their adjustments for preoperative risk. The purpose of this study was to compare the performance of the UHC with the Society of Thoracic Surgeons (STS) risk-adjusted mortality models for adult cardiac surgery and evaluate the contribution of postoperative complications on model performance. ⋯ Although the UHC model demonstrated better performance in the total study population, this difference in performance reflects adjustments for conditions that are postoperative complications. The current UHC models should not be used for quality benchmarks.
