    Introduction: Achieving optimal vancomycin dosing, particularly in septic critically ill patients receiving continuous renal replacement therapy (CRRT) is crucial. Established guidelines recommend the use of trough concentrations to manage vancomycin dosing in adult patients with gram-positive infections. Importantly, obtaining the area under the plasma concentration-time curve (AUC), based on the pharmacokinetic / pharmacodynamics (PK/PD) concept, is extremely required. Objective: This study aimed to describe the pharmacokinetics (PK) of vancomycin in Malaysian critically ill patients receiving CRRT, and the achievement of its therapeutic target, the ratio of the AUC to the minimum inhibitory concentration (MIC) of causative pathogen (AUC/ MIC >400), using a standard dosing regimen (750 mg 12 hourly). Methodology: This was a prospective PK study of vancomycin using standard dosing regimen, in critically ill patients receiving continuous venovenous haemofiltration (CVVH). Blood samples were collected at ten sampling times during a dosing interval. PK analyses were evalu- ated using non-compartmental method. Vancomycin trough concen- trations (15-20 mg/L), and the achievement of the ratio of AUC/ MIC>400, based on selected susceptibility breakpoint (MIC1⁄41 mg/L), were evaluated. Results: Fifty blood samples from five PK profiles of five patients were analysed. The median (interquartile range) of vancomycin total clear- ance (CLtotal) and volume of distribution (Vd) were 62.8 (45.1-62.7) mL/ min and 62.0 (48.7-94.2) L respectively, during CVVH. Maximum concentration, Cmax[30.8 (30.5-33.2) mg/L] was observed at 1.8`0.3 h. The standard dosing regimen (750 mg 12 hourly) resulted in AUC0-24 and Cmin of 400.1 (399.0-504.1) mg.h/L and 12.1 (10.7-16.1) mg/L, respectively. Of these, only two patients, who were anuric, obtained trough concentration between 15-20 mg/L and subsequently achieved the targeted AUC/MIC>400 (MIC1⁄41 mg/L). Conclusion: Obtaining trough concentration between 15-20 mg/L rela- tively achieved the desired AUC/MIC >400 for vancomycin during CVVH. Higher trough concentration (e.g 20-25 mg/L) may be required when targeting for a higher MIC (e.g >1mg/L). Initiation of a higher dosing regimen could also be necessary, particularly in patients undergoing CVVH with significant residual native renal function. Further data is required, from continuation of this study, to clarify the findings

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    Importance: Tracheal intubation is one of the most commonly performed and high-risk interventions in critically ill patients. Limited information is available on adverse peri-intubation events. Objective: To evaluate the incidence and nature of adverse peri-intubation events and to assess current practice of intubation in critically ill patients. Design, Setting, and Participants: The International Observational Study to Understand the Impact and Best Practices of Airway Management in Critically Ill Patients (INTUBE) study was an international, multicenter, prospective cohort study involving consecutive critically ill patients undergoing tracheal intubation in the intensive care units (ICUs), emergency departments, and wards, from October 1, 2018, to July 31, 2019 (August 28, 2019, was the final follow-up) in a convenience sample of 197 sites from 29 countries across 5 continents. Exposures: Tracheal intubation. Main Outcomes and Measures: The primary outcome was the incidence of major adverse peri-intubation events defined as at least 1 of the following events occurring within 30 minutes from the start of the intubation procedure: cardiovascular instability (either: systolic pressure <65 mm Hg at least once, <90 mm Hg for >30 minutes, new or increase need of vasopressors or fluid bolus >15 mL/kg), severe hypoxemia (peripheral oxygen saturation <80%) or cardiac arrest. The secondary outcomes included intensive care unit mortality. Results: Of 3659 patients screened, 2964 (median age, 63 years; interquartile range [IQR], 49-74 years; 62.6% men) from 197 sites across 5 continents were included. The main reason for intubation was respiratory failure in 52.3% of patients, followed by neurological impairment in 30.5%, and cardiovascular instability in 9.4%. Primary outcome data were available for all patients. Among the study patients, 45.2% experienced at least 1 major adverse peri-intubation event. The predominant event was cardiovascular instability, observed in 42.6% of all patients undergoing emergency intubation, followed by severe hypoxemia (9.3%) and cardiac arrest (3.1%). Overall ICU mortality was 32.8%. Conclusions and Relevance: In this observational study of intubation practices in critically ill patients from a convenience sample of 197 sites across 29 countries, major adverse peri-intubation events - in particular cardiovascular instability - were observed frequently
