Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

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

Subtotal hepatectomy in swine for studying small-for-size syndrome and portal inflow modulation: is it reliable?

AbstractBackgroundSmall-for-size syndrome (SFSS) is a feared complication of extended liver resection and partial liver transplantation. Swine models of extended hepatectomy have been developed for studying SFSS and its different treatment options. Although portal inflow modulation (PIM) by splenectomy or splenic artery ligation (SAL) has been proposed in humans to prevent SFSS, such procedures have not yet been evaluated in swine.ObjectivesThe present study was designed to evaluate modifications in splanchnic haemodynamics yielded by extended hepatectomy with and without PIM in swine.MethodsNineteen animals underwent 70% hepatectomy (H70, n = 7), 90% hepatectomy (H90, n = 7) or sham laparotomy (H0, n = 5). Haemodynamic measurements were performed at baseline, after hepatectomy and after PIM by SAL and splenectomy.ResultsPortal vein flow increased after both H70 (273 ml/min/100 g versus 123 ml/min/100 g; P = 0.016) and H90 (543 ml/min/100 g versus 124 ml/min/100 g; P = 0.031), but the hepatic venous pressure gradient (HVPG) increased only after H90 (10.0 mmHg versus 3.7 mmHg; P = 0.016). Hepatic artery flow did not significantly decrease after either H70 or H90. In all three groups, neither splenectomy nor SAL induced any changes in splanchnic haemodynamics.ConclusionsSubtotal hepatectomy of 90% in swine is a reliable model for SFSS inducing a significant increase in HVPG. However, in view of the relevant differences between swine and human splanchnic anatomy, this model is inadequate for studying the effects of PIM by SAL and splenectomy

Outcomes of Stenotrophomonas maltophilia hospital-acquired pneumonia in intensive care unit: a nationwide retrospective study

International audienceBackground: There is little descriptive data on Stenotrophomonas maltophilia hospital-acquired pneumonia (HAP) in critically ill patients. The optimal modalities of antimicrobial therapy remain to be determined. Our objective was to describe the epidemiology and prognostic factors associated with S. maltophilia pneumonia, focusing on antimicrobial therapy.Methods: This nationwide retrospective study included all patients admitted to 25 French mixed intensive care units between 2012 and 2017 with hospital-acquired S. maltophilia HAP during intensive care unit stay. Primary endpoint was time to in-hospital death. Secondary endpoints included microbiologic effectiveness and antimicrobial therapeutic modalities such as delay to appropriate antimicrobial treatment, mono versus combination therapy, and duration of antimicrobial therapy.Results: Of the 282 patients included, 84% were intubated at S. maltophilia HAP diagnosis for duration of 11 [5-18] days. The Simplified Acute Physiology Score II was 47 [36-63], and the in-hospital mortality was 49.7%. Underlying chronic pulmonary comorbidities were present in 14.1% of cases. Empirical antimicrobial therapy was considered effective on S. maltophilia according to susceptibility patterns in only 30% of cases. Delay to appropriate antimicrobial treatment had, however, no significant impact on the primary endpoint. Survival analysis did not show any benefit from combination antimicrobial therapy (HR = 1.27, 95%CI [0.88; 1.83], p = 0.20) or prolonged antimicrobial therapy for more than 7 days (HR = 1.06, 95%CI [0.6; 1.86], p = 0.84). No differences were noted in in-hospital death irrespective of an appropriate and timely empiric antimicrobial therapy between mono- versus polymicrobial S. maltophilia HAP (p = 0.273). The duration of ventilation prior to S. maltophilia HAP diagnosis and ICU length of stay were shorter in patients with monomicrobial S. maltophilia HAP (p = 0.031 and p = 0.034 respectively).Conclusions: S. maltophilia HAP occurred in severe, long-stay intensive care patients who mainly required prolonged invasive ventilation. Empirical antimicrobial therapy was barely effective while antimicrobial treatment modalities had no significant impact on hospital survival.Trial registration: clinicaltrials.gov, NCT03506191

In-Hospital Mortality-Associated Factors of Thrombotic Antiphospholipid Syndrome Patients Requiring Intensive Care Unit Admission

International audienceBackground: The antiphospholipid syndrome (APS) is a systemic autoimmune disease defined by thrombotic events that can require ICU admission because of organ dysfunction related to macrovascular and/or microvascular thrombosis. Critically ill patients with thrombosis and APS were studied to gain insight into their prognoses and in-hospital mortality-associated factors.Methods: This French national, multicenter, retrospective study included all patients with APS and any new thrombotic manifestations admitted to 24 ICUs (January 2000-September 2018).Results: During the study period, 134 patients (male/female ratio, 0.4) with 152 APS episodes were admitted to the ICU (mean age at admission, 46.0 ± 15.1 years). In-hospital mortality of their 134 last episodes was 35 of 134 (26.1%). The Cox multivariable model retained certain factors (hazard ratio [95% CI]: age ≥ 40 years, 11.4 [3.1-41.5], P < .0001; mechanical ventilation, 11.0 [3.3-37], P < .0001; renal replacement therapy, 2.9 [1.3-6.3], P = .007; and in-ICU anticoagulation, 0.1 [0.03-0.3], P < .0001) as independently associated with in-hospital mortality. For the subgroup of definite/probable catastrophic APS, the Cox bivariable model (including the Simplified Acute Physiology Score II score) retained double therapy (corticosteroids + anticoagulant, 0.2 [0.07-0.6]; P = .005) but not triple therapy (corticosteroids + anticoagulant + IV immunoglobulins or plasmapheresis: hazard ratio, 0.3 [0.1-1.1]; P = .07) as independently associated with in-hospital mortality.Conclusions: In-ICU anticoagulation was the only APS-specific treatment independently associated with survival for all patients. Double therapy was independently associated with better survival of patients with definite/probable catastrophic APS. In these patients, further studies are needed to determine the role of triple therapy

Prone Positioning in Patients with COVID-19: Analysis of Multicenter Registry Data and Meta-analysis of Aggregate Data

Background/Aim: Evidence suggests a beneficial effect of prone positioning (PP) in COVID-19. Materials and Methods: Meta-analysis of individual (7 investigators’ groups) and aggregate data (PubMed/EMBASE) regarding the impact of PP on the ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PO2/FiO2) in patients with COVID-19. Results: Among 121 patients (mean age±SD 59.1±10.7 years, 55% males, 57% intubated) the mean post-versus pre- PP PO2/FiO2 difference was: (i) 50.4±64.3 mmHg, p&amp;lt;0.01, (ii) similar in awake (58.7±72.1 mmHg) versus intubated patients (44.1±57.5 mmHg, p=NS), (iii) inversely correlated with body mass index (r=–0.43, p&amp;lt;0.01). Meta-analysis of 23 studies (n=547, weighted age 58.3±4.1, 73% males, 59% intubated) showed a pooled PO2/FiO2 difference of 61.8 [95% confidence intervals=49.9-73.6] mmHg. Meta-regression analysis revealed no associations with baseline demographics, the time in PP before assessment, and the risk of bias of the studies. Conclusion: PP seems to improve oxygenation of patients with COVID-19. © 2022 International Institute of Anticancer Research. All rights reserved
