Abstract BACKGROUND: Postoperative delirium is a common complication of cardiac surgery associated with higher morbidity, longer hospital stay, risk of cognitive decline, dementia, and mortality. Geriatric patients, patients undergoing cardiac surgery, and intensive care patients are at a high risk of developing a postoperative delirium. A gold standard assessment or biomarkers to predict risk factors for delirium, cognitive decline, and dementia in patients undergoing cardiac surgery are not yet available. METHODS: The FINDERI trial (FINd DElirium RIsk factors) is a prospective, single-center, observational pilot study. In total, 500 patients aged ≥ 50 years undergoing cardiac surgery at the Department of Cardiovascular and Thoracic Surgery of the University of Göttingen Medical Center will be recruited. Our primary aims are to validate a delirium screening questionnaire and to identify specific preoperative risk factors and perioperative exposition factors for postoperative delirium, cognitive decline, and accelerated dementia after cardiac surgery. Our secondary aim is to identify blood-based biomarkers that predict the incidence of postoperative delirium, cognitive decline, or dementia in the context of cardiac surgery. CONCLUSION: This prospective, observational pilot trial might help to identify pre- and perioperative risk factors and biomarkers for postoperative delirium, cognitive decline, and dementia. The predictive value of a delirium screening questionnaire in cardiac surgery might also be revealed.TRIAL REGISTRATION: Ethics approval for this study was obtained from the IRB of the University of Göttingen Medical Center. The investigators registered this study in German Clinical Trials Register (DRKS) (DRKS00025095) on April, 19th 2021 https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00025095.

IntroductionPostoperative delirium is common among older cardiac surgery patients. Often difficult to predict and address prophylactically, delirium complicates the postoperative course by increasing morbidity and mortality as well as prolonging both hospital and intensive care unit (ICU) lengths of stay. Based on our pilot trial, we intend to study the effect of scheduled 6-hourly acetaminophen administration for 48 hours post-cardiac surgery with cardiopulmonary bypass (CPB) on the incidence of in-hospital delirium and long-term neurocognitive outcomes. Additionally, effect on duration and severity of delirium, rescue analgesic consumption, acute and chronic pain scores and lengths of hospital and ICU stay will also be explored.Methods and analysisThis multicentre, randomised, placebo-controlled, quadruple-blinded trial will include 900 older (>60 years) cardiac surgical patients requiring CPB. Patients meeting the inclusion criteria and not meeting any exclusion criteria will be enrolled at seven centres across the USA with Beth Israel Deaconess Medical Center (BIDMC), Boston, as the central coordinating centre. Additional sites may be included to broaden or speed accrual. The primary outcome measure is the incidence of in-hospital delirium till day 30. Secondary outcomes include the duration and severity of in-hospital delirium, hospital and ICU lengths of stay, postoperative pain scores, postoperative rescue analgesic consumption, postoperative cognitive function and chronic sternal pain. Creation of a biorepository and the use of intraoperative-blinded electroencephalogram (EEG) and cerebral oximetry data will support exploratory endpoints to determine mechanistic predictors of postoperative delirium.Ethics and disseminationThis trial is approved and centrally facilitated by the Institutional Review Board at BIDMC. An independent Data Safety and Monitoring Board is responsible for maintaining safety oversight. Protocol # 2019 P00075, V.1.4 (dated 20 October 2020).Trial registration numberNCT04093219.

Background: Atrial fibrillation (AF) following cardiac surgery is common and has clinical impact on morbidity. The preoperative and intraoperative risk factors are still not well defined. The objective of the study was to examine preoperative and intraoperative risk factors for AF following cardiac surgery. Methods: A retrospective analysis of a database of cardiac surgeries was performed during 2017-2019 at Poriya Medical Center. Preoperative factors and intraoperative were recorded. Results: 208 patients were included in this analysis. Overall AF following cardiac surgery was detected in 50 (24%) patients. Of 175 patients who did not have history of AF prior to surgery, 27 (15.5%) had post-operative AF. In the 33 patients with previous AF, AF following surgery was detected in 23 (70%). Patients with AF following surgery who were older (66.2±8.0 vs. 60.7± 11.4 years, p=0.002), were treated more with anti-arrhythmic drugs (18.9% vs 4.5, p<0.001), and had higher rates of pre-operative AF (46% vs 6.3%, p=0.0001), prior cerebral vascular accidents (14% vs 4.4%, p=0.019), and prior valve replacement (10% vs 1.9%, p=0.009) compared to patients without AF following surgery. In multivariate Cox regression analysis, age (HR 1.04, CI 1.01-1.07, P=0.006) and history of preoperative AF (HR 6.01, CI 3.42-10.57, P<0.001) were predictors of AF following cardiac surgery. The probability of being free of postsurgical AF was 80% among patients without history of AF compared to 30% in patients with previous AF history (p<0.001). Conclusion: Preoperative AF and age were predictors of AF following cardiac surgery

AbstractBackground and Objective:At the University Medical Center Utrecht (UMCU), follow-up implies an inventory of risk factors and screening for MRSA colonization among all MRSA-positive patients for at least 6 months. If risk factors or positive cultures persist or re-emerge, longer follow-up is indicated and isolation at readmission. This study investigated how long MRSA-positive patients remained colonized after hospital discharge and which risk factors were important. Furthermore, the results of eradication therapy were evaluated.Design:All patients who were positive for MRSA at the UMCU between January 1991 and January 2001 were analyzed regarding carriage state, presence of risk factors for prolonged carriage ofStaphylococcus aureus, and eradication treatment.Results:A total of 135 patients were included in the study. The median follow-up time was 1.2 years. Eighteen percent of the patients were dismissed from follow-up 1 year after discharge. Only 5 patients were dismissed after 6 months. Among patients with no risk factors, eradication treatment was effective for 95% within 1 year. Among patients with persistent risk factors, treatment was effective for 89% within 2 years.Conclusions:Based on these findings, eradication therapy should be prescribed for all MRSA carriers, independent of the presence of risk factors. MRSA-positive patients should be evaluated for 6 months for the presence of risk factors and MRSA carriage. Screening for risk factors is important because intermittent MRSA carriage was found in a significant number of our patients. Patients with negative MRSA cultures and without risk factors for 12 months can be safely dismissed from follow-up. (Infect Control Hosp Epidemiol 2005;26:629-633)

Background. Recent studies of risks in cardiopulmonary arrest (CPA) have been performed using large databases from a broad mix of hospital settings. However, these risks might be different in a large, urban, academic medical center. We attempted to validate factors influencing outcomes from CPA at the University of Maryland Medical Center (UMMC). Methods. Retrospective chart review of all adult patients who underwent CPA between 2000 and 2005 at UMMC. Risk factors and outcomes were analyzed with appropriate statistical analysis and compared with published results. Results. 729 episodes of CPA were examined during the study period. Surgical patients had better survival than medical or cardiac patients. Intensive care unit' (ICU) patients had poor survival, but there was no difference on monitored or unmonitored floors. Respiratory etiologies survived better than cardiac etiologies. CPR duration and obesity were negatively correlated with outcome, while neurologic disease, trauma, and electrolyte imbalances improved survival. Age, gender, race, presence of a witness, presence of a monitor, comorbidities, or time of day of CPA did not influence survival, although age was associated with differences in comorbidities. Conclusions. UMMC risk factors for CPA survival differed from those in more broad-based studies. Care should be used when applying the results of database studies to specific medical institutions.

Abstract Background: The aim of our study was to analyze the risk factors of nosocomial infection after cardiac surgery in children with congenital heart disease (CHD). Methods: We performed a retrospective cohort study, and children with CHD who underwent open-heart surgeries at Shanghai Children’s Medical Center from January 1, 2012 to December 31, 2018 were included. The baseline characteristics of these patients of different ages, including neonates (0-1 months old), infants (1-12 months old) and children (1-10 years old), were analyzed, and the association of risk factors with postoperative nosocomial infection were assessed. Results: A total of 11937 subjects were included in the study. The overall nosocomial infection rate was 11.10%. Nosocomial infection rates in neonates, infants, and children with congenital heart disease were 25.41%, 15.78%, and 5.31%, respectively. Multivariate logistic regression analysis found age (OR 0.804, 95%CI: 0.776-0.834; P<0.001), STS risk grade (OR 1.308, 95%CI: 1.203-1.423; P<0.001), body mass index (BMI)

Abstract Background One of the most common complications after cardiac surgery is delirium. Determining the origin of this complication from possible pathomechanisms is difficult. The activation of an inflammatory response during surgery has been suggested as one possible mechanism of delirium. The usefulness of the inflammatory marker procalcitonin (PCT) as a predictor of delirium after cardiac surgery with cardiopulmonary bypass (CBP) has not yet been investigated. Methods The purpose of this study was to prospectively investigate the risk of developing postoperative delirium in a group of elderly patients using a multivariate assessment of preoperative (PCT, comorbidities, functional decline, depression) and intraoperative risk factors. 149 elderly patients were included. Delirium was assessed using the Confusion Assessment Method for the ICU. Results Thirty patients (20%) developed post-operative delirium: hypoactive in 50%, hyperactive in 33%, mixed in 17%. Preoperative PCT above the reference range (> 0.05 ng/mL) was recorded more often in patients who postoperatively developed delirium than in the non-delirium group (50% vs. 27%, p=0.019). After surgery, PCT was significantly higher in the delirium than the non-delirium group: ICU admission after surgery: 0.08 ng/mL, IQR 0.03-0.15 vs. 0.05 ng/mL, IQR 0.02-0.09, p=0.011), and for consecutive days (day 1: 0.59 ng/mL, IQR 0.25-1.55 vs. 0.25 ng/mL, IQR 0.14-0.54, p=0.003; day 2: 1.21 ng/mL, IQR 0.24-3.29 vs. 0.36 ng/mL, IQR 0.16-0.76, p=0.006; day 3: 0.76 ng/mL, IQR 0.48-2.34 vs. 0.34 ng/mL, IQR 0.14-0.66, p=0.001). Patients with delirium were older (74 years, IQR 70 – 76 vs. 69 years, IQR 67 – 74; p=0.038) and more often had functional decline (47% vs. 28%, p=0.041). There was no difference in comorbidities with the exception of anaemia (43% vs. 19%, p=0.006). Depression was detected in 40% of patients with delirium and in 17% without delirium (p=0.005). In a multivariable logistic regression model of preoperative procalcitonin (OR= 3.05; IQR 1.02-9.19), depression (OR=5.02, IQR 1.67-15.10), age (OR=1.14; IQR 1.02-1.26), functional decline (OR=0.76; IQR 0.63-0.91) along with CPB time (OR=1.04; IQR 1.02-1.06) were significant predictors of postoperative delirium. Conclusion A preoperative PCT test and assessment of functional decline and depression may help identify patients at risk for developing delirium after cardiac surgery.
