Abstract: Objectives To evaluate the accuracy of four existing risk stratification models including the Society of Thoracic Surgeons(STS) 2008 Cardiac Surgery Risk Models for Coronary Artery Bypass Grafting (CABG), the European System for Cardiac Operative Risk Evaluation (EuroSCORE), the American College of Cardiology/American Heart Association (ACC/AHA) model, and the initial Parsonnet’s score in predicting early deaths of Chinese patients after CABG procedure. Methods We collected clinical records of 1 559 consecutive patients who had undergone isolated CABG in the Fu WaiHospital from November 2006 to December 2007. There were 264 females (16.93%) and 1 295 males (83.06%) with an average age of 60.87±9.06 years. Early death was defined as death inhospital or within 30 days after CABG. Calibration was assessed by the Hosmer-Lemeshow (H-L) test, and discrimination was assessed by the receiveroperatingcharacteristic (ROC) curve. The endpoint was early death. Results Sixteen patients(1.03%) died early after the operation. STS and ACC/AHA models had a good calibration in predicting the number of early deaths for the whole group(STS: 12.06 deaths, 95% confidence interval(CI) 5.28 to 18.85; ACC/[CM(159mm]AHA:20.67deaths, 95%CI 11.82 to 29.52 ), While EuroSCORE and Parsonnet models overestimated the number of early deaths for the whole group(EuroSCORE:36.44 deaths,95%CI 24.75 to 48.14;Parsonnet:43.87 deaths,95%CI 31.07 to 56.67). For the divided groups, STS model had a good calibration of prediction(χ2=11.46, Pgt;0.1),while the other 3 models showed poor calibration(EuroSCORE:χ2=22.07,Plt;0.005;ACC/AHA:χ2=28.85,Plt;0.005;Parsonnet:χ2=26.74,Plt;0.005).All the four models showed poor discrimination with area under the ROC curve lower than 0.8. Conclusion The STS model may be a potential appropriate choice for Chinese patients undergoing isolated CABG procedure.
Abstract: Objective To evaluate the prediction validation of European system for cardiac operative risk evaluation (EuroSCORE) in prolonged intensive care unit (ICU) stay, mortality, and major postoperative complications for Chinese patients operated for acquired heart valve disease. Methods Between January 2004 and January 2006, 2 218 consecutive patients treated for acquired heart valve diseases were enrolled in Fu Wai Hospital. All these patients accepted valvular surgery. Both logistic model and additive model were applied to EuroSCORE to evaluate its ability in predicting mortality, prolonged ICU stay and major postoperative complications of patients who had undergone heart valve surgery. An receiver operating characteristic curve( ROC) area was used to test the discrimination of the models. Calibration was assessed by HosmerLemeshow goodnessoffit statistic. Results Discriminating abilities of logistic and additive EuroSCORE algorithm were 0.710 and 0.690 respectively for mortality, 0.670 and 0.660 for prolonged ICU stay, 0.650 and 0.640 for heart failure, 0.720 and 0.710 for respiratory failure, 0.700 and 0.740 for renal failure, and 0.540 and 0.550 for reexploration for bleeding. There was significant difference between logistic and additive algorithm in predicting renal failure and heart failure (Plt;0.05). Calibration of logistic and additive algorithm in predicting mortality, prolonged ICU stay and major postoperative complications were not satisfactory. However, logistic algorithm could be used to predict postoperative respiratory failure (P=0.120). Conclusion EuroSCORE is not an accurate predictor in predicting mortality, prolonged ICU stay and major postoperative complications, but the logistic model can be used to predict postoperative respiratory failure in Chinese patients operated for acquired heart valve diseases.
Objective To analyze the early clinical outcome of high-operative-risk coronary artery bypass grafting (CABG) classified according European System for Cardiac Operative Risk Evaluation (EuroSCORE). Methods Classified eighty-four patients accepted CABG from Feb. 2004 to Sep. 2004 in our ward to high-operativerisk group (≥6, n=40) and low-medium-operative-risk group (0-5, n=44) according EuroSCORE. Record the operative schemes, complications after operation and evaluate the severe state with acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) and sequential organ failure assessment(SOFA) for all patients. Compare the early clinical outcome between the two groups. Results The operative mortality, ratio of long ICU-staying time, incidence of complications and severe degree of high-operative-risk group were higher than those in the low-mediumoperative-risk group. Standard EuroSCORE had significant positive correlation with either of A0, A1, Amax or S1, Smax counted in total patients (P〈0. 01), and the same as logistic EuroSCORE (P〈 0. 05). But when compared the relationships in certain risk ranks, only in high-operative-risk group the positive correlation was found between standard EuroSCORE and A1, Amax, S1 and Smax (P〈 0. 05), between logistic EuroSCORE and Amax (P〈 0. 05). Conclusion EuroSCORE could evaluate overall operative risk perfectly in our patients, and maybe more sensitively in the high-operative-risk patients. Many factors could improve the prognosis of high-operative-risk patients: accurate evaluation of the operative risk before surgery; perfect myocardial protection, effective myocardial revascularization and thorough correction of malformation in operation, and proper postoperative management in time.
Objective To evaluate the impact of total thyroidectomy on health-related quality of life (HRQOL) in patients with nodular goiter. Methods The patients who underwent total thyroidectomy from Jan. 2009 to Dec. 2011 in our hospital were retrospectively analyzed with regard to the quality of life (total thyroidectomy group). The patients with similar demographic features who underwent hemithyroidectomy during the same period were matched as control (hemi-thyroidectomy group). The validated HRQOL instrument, which was the Euro quality of life-5D (EQ-5D), was applied to measure the HRQOL. Comparison of HRQOL in patients of 2 groups was performed, meanwhile, the data of total thyroidectomy group was compared with data of normal population who were obtained from The Forth National Health Survey. Results There were 26 and 28 valid questionnaires returned for the total thyroidectomy group and hemithyroi-dectomy group respectively. The demographic features of patients in 2 groups were comparable. No significant variancecould be found between the 2 groups that there were no significant differences on the mobility, self-care, usual activities,pain/discomfort, anxiety/depression, and visual analogous scales (P>0.05). Furthermore, no significant differences in HRQOL were found in EQ-5D questionnaire compared with normal population derived from The Forth National Health Survey (P>0.05), except that there were more patients complained of moderate and severe pain/discomfort in the total thyroidectomy group 〔30.8% (8/26) vs.9.2% (16 330/177 501), P<0.01〕. Conclusion Total thyroidectomy appears to have little impact on the quality of life in the patients with nodular goiter.
ObjectiveTo evaluate the validity of European System for Cardiac Operative Risk Evaluation (EuroSCORE) Ⅱ for predicting in-hospital mortality and prolonged ICU stay after Sun's procedure (total aortic arch replacement with stented elephant trunk implantation) for Stanford type A aortic dissection (STAAD). MethodsClinical data of 384 STAAD patients undergoing Sun's procedure in Beijing Anzhen Hospital between February 2009 and February 2012 were retrospectively analyzed, including 228 (59.38%) patients with acute STAAD. Accoding to EuroSCORE Ⅱ to predict postoperative mortality, all the patients were divided into a low-risk group, a medium-risk group, a high-risk group and an extremely-high-risk group. There were 296 patients including 52 females in the low-risk group with their age of 45.39±10.75 years, 70 patients including 19 females in the medium-risk group with their age of 47.67±11.26 years, 13 patients including 5 females in the high-risk group with their age of 53.08±4.94 years, and 5 patients including 1 female patient in the extremely-high-risk group with their age of 41.60±11.08 years. All the patients received Sun's procedure under deep hypothermic circulatory arrest and antegrade selective cerebral perfusion. EuroSCORE Ⅱ was used to predict postoperative mortality and prolonged ICU stay. ResultsIn-hospital mortality was 8.07% (31/384). Mean length of ICU stay was 3.06 days. Length of ICU stay of 42 patients was longer than 7 days. For low-risk group, the predicted mortality was lower than the actual mortality. For medium-risk, high-risk and extremely-high-risk groups, the predicted mortality was higher than the actual mortality. EuroSCORE Ⅱ showed unsatisfactory discriminatory ability to predict postoperative mortality and prolonged ICU stay. The area under ROC curve were 0.49 and 0.52 respectively. The calibration was also poor for predicting postoperative mortality and prolonged ICU stay (P<0.001). ConclusionsEuroSCORE Ⅱ is not satisfactory for predicting mortality and prolonged ICU stay after Sun's procedure for the treatment of STAAD. A new risk evaluating system specific for STAAD is needed.
ObjectiveTo assess the accuracy of European System for Cardiac Operative Risk Evaluation (EuroSCORE) model in predicting the in-hospital mortality of Uyghur patients and Han nationality patients undergoing heart valve surgery. MethodsClinical data of 361 consecutive patients who underwent heart valve surgery at our center from September 2012 to December 2013 were collected, including 209 Uyghur patients and 152 Han nationality patients. According to the score for additive and logistic EuroSCORE models, the patients were divided into 3 subgroups including a low risk subgroup, a moderate risk subgroup, and a high risk subgroup. The actual and predicted mortality of each risk subgroup were studied and compared. Calibration of the EuroSCORE model was assessed by the test of goodness of fit, discrimination was tested by calculating the area under the receiver operating characteristic (ROC) curve. ResultsThe actual mortality was 8.03% for overall patients, 6.70% for Uyghur patients,and 9.87% for Han nationality patients. The predicted mortality by additive EuroSCORE and logistic EuroSCORE for Uyghur patients were 4.03% and 3.37%,for Han nationality patients were 4.43% and 3.77%, significantly lower than actual mortality (P<0.01). The area under the ROC curve of additive EuroSCORE and logistic EuroSCORE for overall patients were 0.606 and 0.598, for Han nationality patients were 0.574 and 0.553,and for Uyghur patients were 0.609 and 0.610. ConclusionThe additive and logistic EuroSCORE are unable to predict the in-hospital mortality accurately for Uyghur and Han nationality patients undergoing heart valve surgery. Clinical use of these model should be considered cautiously.
European system for cardiac operative risk evaluation(EuroSCORE) is one of the widely used and influential cardiac surgery risk assessment system. It was originally used to predict the quantitative score of probability of death after cardiac surgery. After that, it has been developed to predict long-term mortality and survival rate, ICU residence time, treatment costs, main complications and so on. EuroSCORE Ⅱ is the latest version, which is more accurate in predicting mortality, long term survival rate than the old one. But there are also some limitations as predicting limited range of the end, underestimating the mortality of critically endangered patients, lacking adequate preoperative risk factors and so on. This review article focuses on the production, development and clinical application of EuroSCORE.
Objective To summarize the nutritional assessment methods for liver cancer patients and their development, and to provide reference for rationally nutritional assessment and nutritional support. Method Domestic and foreign literatures were searched to summarize the nutritional assessment methods for liver cancer patients and their development, in order to determine a practical and feasible assessment method. Results The evaluation validity of traditionally nutritional assessment methods which contained many individual indicators was low. But subjective global assessment (SGA), mini nutritional assessment (MNA), and nutritional risk screening 2002 (NRS-2002) had similar evaluation validity, this 3 kinds of nutritional assessment methods were more suitable for liver cancer patients compared with the traditionally nutritional assessment methods. Conclusion The clinician should simultaneously apply SGA, MNA, NRS-2002, and other comprehensively nutritional assessment methods, as well as related anthropometric and laboratory indexes, to get a more accurate assessment of the nutritional status for patients with liver cancer.
