Proteinuria Enhances Prediction Ability of Sequential Organ Failure Assessment Score and Associated with Mortality in Coronary Care Units

摘要


BACKGROUND: Proteinuria is associated with increased morbidity and mortality in patient with cardiac surgery. This investigation explored the impact of proteinuria and its association with the outcomes of patients in coronary care units (CCUs). METHODS: This retrospective study analyzed the CCU medical records between December 2010 and June 2012 of a tertiary care university hospital. Three-month mortality and hospital stay were identified as outcomes. Acute Physiology and Chronic Health Evaluation (APACHE) III and sequential organ failure assessment (SOFA) scores were calculated at admission. RESULTS: A total of 305 adult patients with a mean age of 64.9 years were investigated. Intensive care unit (ICU) stay and hospital stay were longer and the risk of 3-month mortality was higher in patients with proteinuria. Multivariate logistic regression analysis revealed that proteinuria was an independent factor, after adjusting for clinical factors. The incremental prognostic value of proteinuria and SOFA scores was significantly higher than that of SOFA alone (area under the receiver operating characteristic curve [ΔAUROC] = 0.063, P = 0.030). CONCLUSION: CCU patients with proteinuria had poor short-term outcomes and longer hospital stays. Proteinuria enhanced the ability of outcome prediction of SOFA. Urinary proteinuria is a cheap and easytouse tool for identifying high-risk patients.
