The prediction of intensive care unit length of stay (ICU-LOS) could contribute to more efficient ICU resources' allocation and better planning of care among cardiac surgery patients. The aim of this study was to identify the preoperative and intraoperative predictors for prolonged cardiac surgery ICU-LOS. An observational cohort study was conducted among 150 consecutive patients, who were admitted to the cardiac surgery ICU of a tertiary hospital of Athens, Greece from September 2010 to January 2011. Multivariate regression analysis revealed that patients with increased creatinine levels preoperatively (odds ratio (OR) 3.0, P = 0.049), history of atrial fibrillation (AF) (OR 6.3, P = 0.012) and high EuroSCORE values (OR 2.6, P = 0.017) had a significant greater probability to stay in the ICU for more than 2 days. In addition, intraoperative hyperglycemia (OR 3.0, P = 0.004) was strongly associated with longer ICU-LOS. In conclusion, the high perioperative risk, the history of AF and renal dysfunction, and the intraoperative hyperglycemia are significant predictors of prolonged ICU stay. The early identification of patients at risk could allow the efficient ICU resources' allocation and the reduction of healthcare costs. This would contribute to nursing care planning depending on the availability of healthcare personnel and ICU bed capacity.

INTRODUCTION:Readmission in the intensive care unit (ICU) is a significant morbidity index, which has been related to poor patient outcomesAIM:To identify the preoperative and intraoperative risk factors for readmission in the cardiac surgery ICU.METHODS:We conducted a retrospective cohort study of 595 consecutive patients who were admitted to the cardiac surgery ICU of a tertiary hospital of Athens — Greece during the one-year period (September 2011-September 2012). Data collection was carried out, retrospectively, by the use of a short questionnaire and based on the review of medical and nursing patient records at December 2012.RESULTS:The incidence of ICU readmission was 3.7% (22/595). Respiratory disorders were the main reason for readmission (45.4%). Readmitted patients had a significantly higher in-hospital mortality compared to those requiring no readmission (P < 0.001). Multivariate analysis revealed that female gender [for males odds ratio (OR) 0.37, 95% confidence interval (CI) 0.15-0.89], high logistic EuroSCORE (OR 1.02, 95% CI 1.00-1.04), prolonged cardiopulmonary (CPB) duration (OR 1.01, 95% CI 1.00-1.02) and preoperative renal failure (OR 1.02, 95% CI 1.00-1.05) were the independent risk factors for readmission to the cardiac surgery ICU.CONCLUSIONS:One intraoperative and three preoperative variables are associated strongly with higher probability for ICU readmission. Shorter CPB duration could contribute to lower ICU readmission incidence. In addition, the early identification of high risk patients for readmission in the cardiac surgery ICU could encourage both the more efficient healthcare planning and resources allocation.

Introduction: Although, the effects of patient education on the effective anticoagulant management, among patients undergoing heart valve replacement with a mechanical prosthesis, have been reported, the evidence of this association remains inconclusive. Aim: To investigate the effect of a nurse-led patient education program for oral anticoagulant therapy on the incidence of thromboembolic and hemorrhagic episodes after surgical heart valve replacement. Methods: A quasi-experimental study was conducted. Patients were allocated to a) a control group (n=100), including those who received the usual education on oral anticoagulants, and b) an intervention group (n=100), with those who attended a nurse-led education program, postoperatively, including verbal courses and written material through an education booklet. We investigated the incidence of hemorrhagic and thromboembolic episodes three months after patients' hospital discharge. Patients' socio-demographic and clinical characteristics were obtained using a structured short questionnaire and through the medical and nursing patient records review. Patients' follow-up data were collected via phone interviews. Results: The baseline characteristics were similar for both groups. Patients who received nurse-led education on oral anticoagulant therapy had a significantly lower 3-month incidence of hemorrhagic episodes compared with controls (1% vs. 14%, p<0.001). However, we found insignificant differences in the 3-month incidence of thromboembolic events between the two groups. Conclusion: The implementation of a nurse-led education program on oral anticoagulants management failed to show effectiveness on the 3-month incidence of thromboembolic episodes. However, this educational intervention seems to be superior to the general patient education, leading to the significantly lower occurrence of hemorrhagic episodes.

Introduction The impact of cardiac myxomas on the immune response is still indefinite, although laboratory tests and histological findings suggest that there is a correlation between myxomas and inflammatory reaction. Objectives Our study speculates that cardiac myxomas are associated with inflammatory response and investigates potential elements of inflammation in the histopathological examination and biomarkers from laboratory tests. Methods It is a retrospective study and data were collected from a single center between May 2010 to May 2018. Autopsies and laboratory tests of 54 cases were analyzed. Results In 20,4% of the autopsies, inflammatory elements were identified. The neutrophil/lymphocyte ratio (NLR) preoperatively is elevated in patients suffering from cardiac myxoma while its value is correlated to the tumor size. Conclusions Cardiac myxoma is an entity that affects the immune response of patients. The biomarker NLR could be utilized as a prognostic factor regarding enlarged cardiac myxomas. Future studies still need to be conducted in order to confirm the usefulness of this biomarker on cardiac myxomas.
