AKI after cardiac surgery is associated with mortality, prolonged hospital length of stay, use of dialysis, and subsequent CKD. We evaluated the effects of THR-184, a bone morphogenetic protein-7 agonist, in patients at high risk for AKI after cardiac surgery. We conducted a randomized, double-blind, placebo-controlled, multidose comparison of the safety and efficacy of perioperative THR-184 using a two-stage seamless adaptive design in 452 patients between 18 and 85 years of age who were scheduled for nonemergent cardiac surgery requiring cardiopulmonary bypass and had recognized risk factors for AKI. The primary efficacy end point was the proportion of patients who developed AKI according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The proportion of patients who developed AKI within 7 days of surgery was similar in THR-184 treatment groups and placebo groups (range, 74%–79%; P=0.43). Prespecified secondary end point analysis did not show significant differences in the severity of AKI stage (P=0.53) or the total duration of AKI (P=0.44). A composite of death, dialysis, or sustained impaired renal function by day 30 after surgery did not differ between groups (range, 11%–20%; P=0.46). Safety-related outcomes were similar across all treatment groups. In conclusion, compared with placebo, administration of perioperative THR-184 through a range of dose exposures failed to reduce the incidence, severity, or duration of AKI after cardiac surgery in high-risk patients.

Abstract OBJECTIVES Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker that has been implicated in several cardiac pathologies and has been shown to be elevated in critically ill populations. We measured plasma suPAR in a cohort of cardiac surgical patients to evaluate its ability to predict prolonged intensive care unit (ICU) and hospital length of stay and development of complications following surgery. We compared suPAR against EuroSCORE II and C-reactive protein (CRP). METHODS Ninety patients undergoing cardiac surgery were recruited with samples taken preoperatively and on postoperative days 1, 2 and 3. suPAR was measured using enzyme-linked immunosorbent assay. Area under the receiver operator curve (AUROC) was used to test predictive capability of suPAR. Comparison was made with EuroSCORE II and CRP. RESULTS suPAR increased over time (P < 0.001) with higher levels in patients requiring prolonged ICU and hospital stay, and prolonged ventilation (P < 0.05). suPAR was predictive for prolonged ICU and hospital stay, and prolonged ventilation at all time points (AUROC 0.66–0.74). Interestingly, this association was also observed preoperatively, with preoperative suPAR predicting prolonged ICU (AUROC 0.66), and hospital stay (AUROC 0.67) and prolonged ventilation (AUROC 0.74). The predictive value of preoperative suPAR compared favourably to EuroSCORE II and CRP. CONCLUSIONS suPAR increases following cardiac surgery and levels are higher in those who require prolonged ICU stay, prolonged hospital stay and prolonged ventilation. Preoperative suPAR compares favourably to EuroSCORE II and CRP in the prediction of these outcomes. suPAR could be a useful biomarker in predicting outcome following cardiac surgery, helping inform clinical decision-making.

Background: Cardiac surgery (CS) may be associated with several organic repercussions responsible for the appearance of cardiac risk factors during the postoperative period. These, associated with prolonged hospital length of stay (LoS), may trigger critical manifestations in individuals undergoing this surgical procedure. To investigate the relationships between postoperative cardiac risk factors, LoS, and changes in functioning state. Methods: Patients undergoing reconstructive, substitutive, or corrective cardiac surgeries were evaluated. The presence of postoperative cardiovascular risks was assessed using the InsCor score, while LoS and functionality were collected from medical records. Results: One-hundred patients with a mean age of 59.2±12.3 years were included. Significant correlations between functionality and both the hospital and Intensive Care Unit (ICU) LoS (p<0.0001, ρ= 0.56; p=0.002, ρ=0.29, respectively), as well as between hospital LoS and the number of comorbidities (p=0.003, ρ=0.28) were found. No significant relationships were observed between the number of postoperative risk factors and LoS. Conclusions: Functionality and comorbidities are associated with increased hospital and ICU LoS in patients undergoing cardiac surgery.

Abstract Background Delirium is an acute cognitive disorder that presents with fluctuation in cognition, apathy, and non-organized thinking, resulting in increased morbidity, mortality, intensive care unit (ICU) stay, and total healthcare costs. In patients undergoing cardiac surgery, delirium also increases the risk of postoperative complications, such as respiratory insufficiency, sternum instability, and need for re-operation of the sternum. This study aims to understand the incidence of delirium in patients after cardiac surgery in patients sedated with remimazolam besylate versus propofol. Methods In this prospective, double-blind, randomized controlled clinical trial, we aim to recruit 200 patients undergoing cardiac surgery between January 1, 2021, and December 31, 2021, who will be randomized to receive either remimazolam besylate or propofol infusions postoperatively, until they are extubated. The primary outcome is the incidence of delirium within 5 days after surgery. Secondary outcomes include the time of delirium onset, duration of delirium, ICU length of stay, hospital length of stay, and mechanical ventilation time. Discussion The key objective of this study is to assess whether remimazolam besylate reduces the incidence of delirium in patients after cardiac surgery compared to propofol sedation. In this preliminary randomized controlled clinical trial, we will test the hypothesis that the use of remimazolam besylate lowers the incidence of delirium when compared to propofol in patients undergoing cardiac surgery.

Abstract Background Unnecessary and prolonged IV vancomycin exposure increases risk of adverse drug events, notably nephrotoxicity, which may result in prolonged hospital length of stay. The purpose of this study is to identify areas of improvement in antimicrobial stewardship for vancomycin appropriateness by clinical pharmacists at the time of therapeutic drug monitoring (TDM). Methods Retrospective, observational cohort study at an academic medical center and a community hospital. Inclusion: patient over 18 years, received at least three days of IV vancomycin where the clinical pharmacy TDM service assessed for appropriate continuation for hospital admission between June 19, 2019 and June 30, 2019. Exclusion: vancomycin prophylaxis or administered by routes other than IV. Primary outcome was to determine the frequency and clinical components of inappropriate vancomycin continuation at the time of TDM. Inappropriate vancomycin continuation was defined as cultures positive for methicillin-susceptible Staphylococcus aureus (MRSA), vancomycin-resistant bacteria, and non-purulent skin and soft tissue infection (SSTI) in the absence of vasopressors. Data was reported using descriptive statistics and measures of central tendency. Results 167 patients met inclusion criteria with 38.3% from the ICU. SSTIs were most common indication 39 (23.4%) cases, followed by pneumonia and blood with 34 (20.4%) cases each. At time of vancomycin TDM assessment, vancomycin continuation was appropriate 59.3% of the time. Mean of 4.22 ± 2.69 days of appropriate vancomycin use, 2.18 ± 2.47 days of inappropriate use, and total duration 5.42 ± 2.94. 16.4% patients developed an AKI. Majority of missed opportunities were attributed to non-purulent SSTI (28.2%) and missed MRSA nares swabs in 21% pneumonia cases (table 1). Conclusion Vancomycin is used extensively for empiric treatment of presumed infections. Appropriate de-escalation of vancomycin therapy is important to decrease the incidence of adverse effects, decreasing hospital length of stay, and reduce development of resistance. According to the mean duration of inappropriate therapy, there are opportunities for pharmacy and antibiotic stewardship involvement at the time of TDM to optimize patient care (table 1).

Background: Data from Clostridium difficile infection (CDI) in neutropenic patients are still scarce. Objective: To assess outcomes of CDI in patients with and without neutropenia. Methods: The study included a retrospective cohort of adult patients at 3 academic hospitals between January 2013 and December 2017. The 2 study arms were neutropenic patients (neutrophil count <500/mm3) and nonneutropenic patients with confirmed CDI episodes. The primary outcome evaluated the composite end point of all-cause in-hospital mortality, intensive care unit (ICU) admissions, and treatment failure at 7 days. The secondary outcome evaluated hospital length of stay. Results: Of 962 unique cases of CDI, 158 were neutropenic (59% men) and 804 were nonneutropenic (46% men). The median age was 57 years (IQR, 44–64) in the neutropenic group and 68 years (IQR, 56–79) in the nonneutropenic group. The median Charlson comorbidity score was 5 (IQR, 3–7.8) and 4 (IQR, 3–5) in the neutropenic and nonneutropenic groups, respectively. Regarding severity, 88.6% versus 48.9% were nonsevere, 8.2% versus 47% were severe, and 3.2% versus 4.1% were fulminant in the neutropenic and nonneutropenic groups, respectively. Also, 63% of patients (60.9% in nonneutropenic, 65.2% in neutropenic) were exposed to proton-pump inhibitors. A combination CDI treatment was required in 53.2% of neutropenic patients and 50.1% of nonneutropenic patients. The primary composite end point occurred in 27% of neutropenic patients versus 22% of nonneutropenic patients (P = .257), with an adjusted odds ratio of 1.30 (95% CI, 0.84–2.00). The median hospital length of stay after controlling for covariates was 21.3 days versus 14.2 days in the neutropenic and nonneutropenic groups, respectively (P < .001). Complications (defined as hypotension requiring vasopressors, ileus, or bowel perforation) were seen in 6.0% of the nonneutropenic group and 4.4% of the neutropenic group (P = .574), with an adjusted odds ratio of 0.61 (95% CI, 0.28–1.45). Conclusions: Neutropenic patients were younger and their cases were less severe; however, they had lower incidences of all-cause in-hospital mortality, ICU admissions, and treatment failure. Hospital length of stay was significantly shorter in the neutropenic group than in the nonneutropenic group.Funding: NoneDisclosures: None

Background: Acute pyelonephritis is a bacterial infection of the upper urinary tract. Patients can be admitted to a variety of wards for treatment. However, at the Prince of Wales Hospital in Hong Kong, they are managed initially in the emergency medicine ward. The aim of the study is to identify the risk factors that are associated with a prolonged hospital length of stay. Methods: This was a retrospective cohort study conducted in Prince of Wales Hospital. The study recruited patients who were admitted to the emergency medicine ward between 1 January 2014 and 31 December 2017. These patients presented with clinical features of pyelonephritis, received antibiotic treatment and had a discharge diagnosis of pyelonephritis. The length of stay was measured and any length of stay over 72 h was considered to be prolonged. Results: There were 271 patients admitted to the emergency medicine ward, and 118 (44%) had a prolonged hospital length of stay. Univariate and multivariate analyses showed that the only statistically significant predictor of prolonged length of stay was a raised C-reactive protein (odds ratio 1.01; 95% confidence 1.01–1.02; p < 0.0001). Out of 271 patients, 261 received antibiotics in the emergency department. All 10 patients (8.5%) who did not receive antibiotics in emergency department had a prolonged length of stay (p = 0.0002). Conclusion: In this series of acute pyelonephritis treated in the emergency medicine ward, raised C-reactive protein levels were predictive for prolonged length of stay. Patients who did not receive antibiotics in the emergency department prior to emergency medicine ward admission had prolonged length of stay.
