Influenza Pneumonia

Background and aimsThe relationship between early oseltamivir treatment (within 48 h of symptom onset) and mortality in patients admitted to intensive care units (ICUs) with severe influenza is disputed. This study aimed to investigate the association between early oseltamivir treatment and ICU mortality in critically ill patients with influenza pneumonia.MethodsThis was an observational study of patients with influenza pneumonia admitted to 184 ICUs in Spain. The primary outcome was to evaluate the association between early oseltamivir treatment and ICU mortality compared to later treatment. Secondary outcomes were to compare the duration of mechanical ventilation (MV) and the ICU length of stay between the early and later oseltamivir treatment groups. To reduce biases related to observational studies, propensity score matching and a competing risk analysis were performed.ResultsDuring the study period, 2124 met the inclusion criteria. All patients had influenza pneumonia and received oseltamivir before ICU admission. Of these, 529 (24.9%) received early oseltamivir treatment. In the multivariate analysis, early treatment was associated with reduced ICU mortality (OR 0.69, 95% CI 0.51–0.95). After propensity score matching, early oseltamivir treatment was associated with improved survival rates in the Cox regression (HR 0.77, 95% CI 0.61–0.99) and competing risk (sHR 0.67, 95% CI 0.53–0.85) analyses. The ICU length of stay and duration of MV were shorter in patients receiving early treatment.ConclusionsEarly oseltamivir treatment is associated with improved survival rates in critically ill patients with influenza pneumonia and may decrease ICU length of stay and MV duration.

Abstract Background: Mechanical power (MP), defined as the amount of energy produced by mechanical ventilation and released into the respiratory system, has long been considered a critical factor in the pathogenesis of ventilator-induced lung injury. However, our knowledge suggests that the effects of MP may be proportional to their involvement in total lung function size. Therefore, MP normalized to predicted body weight (norMP) should be greater than absolute MP value. The objective of this research is to determine the connection between norMP and mortality in critically ill patients who have been on invasive ventilation for at least 48 hours.Methods: This is a study of data stored in the databases of the MIMIC–III, which contains data of critically ill patients for over 50,000. The study involved critically ill patients who had been on invasive ventilation for at least 48 hours. norMP was the relevant exposure. The major endpoint was ICU mortality, the secondary endpoints were 30-day, 90-day mortality; ICU length of stay, the number of ventilator-free days at day 28.Result: The study involved a total of 1301 critically ill patients. This study revealed that norMP was correlated with ICU mortality [OR per quartile increase 1.20 (95% CI 1.07–1.35), p = 0.009]. Similarly, norMP was correlated with ventilator-free days at day 28, ICU length of stay. In the subgroup analysis, high norMP was associated with ICU mortality whether low or high Vt (OR 1.22, 95% CI 1.01–1.47, p = 0.040; OR 1.28, 95% CI 1.06–1.54, p = 0.011, respectively). But high norMP was associated with ICU mortality only in low PIP (OR 1.18, 95% CI 1.01–1.37, p = 0.034)Conclusion: Our findings indicate that higher norMP is independently linked with elevated ICU mortality and various other clinical findings in critically ill patients with a minimum of 48 hours of invasive ventilation.

Abstract Background Mechanical power (MP), defined as the amount of energy produced by mechanical ventilation and released into the respiratory system, was reportedly a determining factor in the pathogenesis of ventilator-induced lung injury. However, previous studies suggest that the effects of MP were proportional to their involvement in the total lung function size. Therefore, MP normalized to the predicted body weight (norMP) should outperform the absolute MP value. The objective of this research is to determine the connection between norMP and mortality in critically ill patients who have been on invasive ventilation for at least 48 h. Methods This is a study of data stored in the databases of the MIMIC–III, which contains data of critically ill patients for over 50,000. The study involved critically ill patients who had been on invasive ventilation for at least 48 h. norMP was the relevant exposure. The major endpoint was ICU mortality, the secondary endpoints were 30-day, 90-day mortality; ICU length of stay, the number of ventilator-free days at day 28. Result The study involved a total of 1301 critically ill patients. This study revealed that norMP was correlated with ICU mortality [OR per quartile increase 1.33 (95% CI 1.16–1.52), p <  0.001]. Similarly, norMP was correlated with ventilator-free days at day 28, ICU length of stay. In the subgroup analysis, high norMP was associated with ICU mortality whether low or high Vt (OR 1.31, 95% CI 1.09–1.57, p = 0.004; OR 1.32, 95% CI 1.08–1.62, p = 0.008, respectively). But high norMP was associated with ICU mortality only in low PIP (OR 1.18, 95% CI 1.01–1.38, p = 0.034). Conclusion Our findings indicate that higher norMP is independently linked with elevated ICU mortality and various other clinical findings in critically ill patients with a minimum of 48 h of invasive ventilation.

Abstract Background Dexmedetomidine (DEX) had organ protection effects and could decrease mortality in animal models, but its association with mortality and length of stay (LOS) in ICU and hospital in critically ill patients was conflicting. Whether acute kidney injury (AKI) subgroup of critically ill patients could benefit from DEX was unknown. The present study aimed to evaluate the effects of DEX on clinical outcomes of critically ill patients with AKI. Methods Data were extracted from the Medical Information Mart for Intensive Care Ⅲ database (MIMIC Ⅲ). Propensity score matching (PSM) analysis (1:3), cox proportional hazards model, linear regression and logistic regression model were used to assess the effect of DEX on clinical outcomes. Results After PSM, 324 pairs of patients were matched between the patients with DEX administration and those without. DEX administration was associated with decreased in-hospital mortality [hazard ratio (HR) 0.287; 95% CI 0.151–0.542; P < 0.001] and 90-day mortality [HR 0.344; 95% CI 0.221–0.534; P < 0.001], and it was also associated with reduced length of stay (LOS) in ICU [4.54(3.13,7.72) versus 5.24(3.15,10.91), P < 0.001] and LOS in hospital [11.63(8.02,16.79) versus 12.09(7.83,20.44), P = 0.002]. Subgroup analysis showed the above associations existed only in mild and moderate AKI subgroups, but not in severe AKI subgroup. Nevertheless, DEX administration was not associated with the recovery of renal function [HR 1.199; 95% CI 0.851–1.688; P = 0.300]. Conclusions DEX administration improved outcomes in critically ill patients with mild and moderate AKI and could be a good choice of sedation.

The Impact

Summary Background Coronavirus disease 2019 (COVID-19) disrupts routine care and alters treatment pathways in every medical specialty, including intensive care medicine, which has been at the core of the pandemic response. The impact of the pandemic is inevitably not limited to patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and their outcomes; however, the impact of COVID-19 on intensive care has not yet been analyzed. Methods The objective of this propensity score-matched study was to compare the clinical outcomes of non-COVID-19 critically ill patients with the outcomes of prepandemic patients. Critically ill, non-COVID-19 patients admitted to the intensive care unit (ICU) during the first wave of the pandemic were matched with patients admitted in the previous year. Mortality, length of stay, and rate of readmission were compared between the two groups after matching. Results A total of 211 critically ill SARS-CoV‑2 negative patients admitted between 13 March 2020 and 16 May 2020 were matched to 211 controls, selected from a matching pool of 1421 eligible patients admitted to the ICU in 2019. After matching, the outcomes were not significantly different between the two groups: ICU mortality was 5.2% in 2019 and 8.5% in 2020, p = 0.248, while intrahospital mortality was 10.9% in 2019 and 14.2% in 2020, p = 0.378. The median ICU length of stay was similar in 2019: 4 days (IQR 2–6) compared to 2020: 4 days (IQR 2–7), p = 0.196. The rate of ICU readmission was 15.6% in 2019 and 10.9% in 2020, p = 0.344. Conclusion In this retrospective single center study, mortality, ICU length of stay, and rate of ICU readmission did not differ significantly between patients admitted to the ICU during the implementation of hospital-wide COVID-19 contingency planning and patients admitted to the ICU before the pandemic.

Abstract Background: Corticosteroids, especially dexamethasone, showed a survival benefit in critically ill COVID 19 patients. However, it is unclear whether the timing of dexamethasone initiation is associated with positive outcomes. The aim of this study is to evaluate the timing of dexamethasone initiation and 30-day ICU mortality in critically ill patients with COVID19. Methods: A multicenter, non-interventional, prospective study for all adult COVID19 admitted to intensive care units (ICUs) who received systemic dexamethasone between March 01 to December 31, 2020. Patients were divided into two groups based on the timing for dexamethasone initiation (early vs. late). Early use defined as the initiation of dexamethasone within three days of ICU admission. Multivariate logistic and generalized linear regression were used. We considered a P value of < 0.05 statistically significant. Results: A total of 475 patients were included in the study; dexamethasone was initiated early within three days of ICU admission in 433 patients. Early initiation of dexamethasone was associated with lower 30-day ICU mortality (OR [95%CI]: 0.43 [0.23, 0.81], p-value = 0.01), and acute kidney injury during ICU stay, (OR [95%CI]: 0.45 [0.21, 0.94], p-value = 0.03). Additionally, among survivors, early initiation was associated with shorter MV duration (beta coefficient [95% CI]: -0.94 [-1.477, -0.395], p-value = 0.0001), ICU length of stay (LOS) (beta coefficient [95%CI]: -0.73 [-0.9971, -0.469], p-value = 0.0001), and hospital LOS (beta coefficient [95%CI]: -0.68 [-0.913, -0.452], p-value = 0.0001). Conclusion: Early initiation of dexamethasone within three days of ICU admission in COVID-19 critically ill patients was associated with a mortality benefit. Additionally, it was associated with shorter MV duration, hospital, and ICU LOS.

Purpose: Hypophosphatemia is reported in up to 5% of hospitalized patients and ranges from 20% to 80% in critically ill patients. The consequences of hypophosphatemia for critically ill patients remain controversial. We evaluated the effect of hypophosphatemia on mortality and length of stay in intensive care unit (ICU) patients. Methods: MEDLINE, EMBASE, Cochrane Library (Reviews and Trials), and PubMed were searched for articles in English. The primary outcome was mortality and secondary outcome was length of stay. The quality of evidence was graded using a modified Newcastle-Ottawa Scale. Results: Our search yielded 828 articles and ultimately included 12 studies with 7626 participants in the analysis. Hypophosphatemia was associated with increased hospital length of stay (2.19 days [95% CI, 1.74-2.64]) and ICU length of stay (2.22 days [95% CI, 1.00-3.44]) but not mortality (risk ratio: 1.13 [95% CI, 0.98-1.31]; P = .09). Conclusions: Hypophosphatemia in ICU was associated with increased hospital and ICU length of stay but not all-cause mortality. Hypophosphatemia appears to be a marker of disease severity. Limited number of available studies and varied study designs did not allow for the ascertainment of the effect of severe hypophosphatemia on patient mortality.

Abstract Introduction: Thrombocytopenia is a common occurrence in critically ill patients and results in an array of diagnostic workup. Heparin induced thrombocytopenia (HIT) is one of the most frequently ordered tests in this scenario, although it is a less common cause (0.02-0.5%) The over testing and treatment of HIT in Intensive Care Unit (ICU) can lead to a change in medications, and result in side effects, increased ICU length of stay and increased costs. Current guidelines recommend 4-Ts criteria to evaluate the clinical HIT probability in general population, but it may also be used in Intensive Care Unit (ICU) patients. Here, we want to analyze the the usage of 4Ts score in a community hospital and to understand its correlation with HIT testing to see if HIT testing could have been avoided. Methods: We performed a retrospective chart review of adult patients who underwent testing for Heparin Induced Thrombocytopenia anti-platelet factor 4 antibody (anti- PF4 Ab) in ICU at our institution from 03/01/2012 to 02/01/2018. The primary outcomes were set to identify (1) the extent of inappropriate of HIT testing and its consequences in patients with low 4Ts scores, and (2) if 4Ts score as a potential predictor of length of stay and mortality in ICU. As a secondary outcome, we assessed if Body Mass Index (BMI) and Recent Surgery are related to false positive anti-PF4 Ab test. Kruskal-Wallis test and Fisher Exact test were used. Results: A total of 66 patients were identified. The mean age was 64 yr and the male-female ratio was similar. 40 patients had recent surgery in the past 3 months. The cause of thrombocytopenia other than HIT was possible or definite in 62 patients with sepsis being the most common cause (56.45%). 30 patients had low probability 4-Ts scores, 28 had intermediate and 7 had high probability. HIT was confirmed (Serotonin Release Assay-SRA positive) in 0%, 7.14% and 12.5% of patients with low, intermediate and high probability 4Ts scores, respectively. In the patients with low probability 4Ts and anti-PF4 Ab testing, heparin was held in 24 (80%) and the anti-coagulation was switched (to either fondaparinux or argatroban) in 10 (33.33%). In those patients with anticoagulation switch, 3 had minor bleeding. There was no difference in the ICU length of stay (p=0.1712) and mortality (p=0.149) between patients with low, intermediate and high probability 4Ts scores. Patients with BMI ≥40 kg/m2 had twice the percentage of false positive anti-PF4 Ab testing compared with the rest, but the results were not significant (p=0.285). Recent surgery was not related to the false positive anti-PF4 Ab testing (p=1). Conclusion: As no patient with low-probability 4Ts score had confirmed HIT, low 4Ts may be a good estimator of the unlikeliness of HIT even in critically ill patients. We found discrepancy in the recommendations and usage of Anti-PF4 Ab testing in our institution. This has resulted in switching of heparin to other, more expensive anti-coagulations. This may very well be the situation in many other similar institutions. This could partly be due to lack of awareness of HIT testing guidelines in the critical care setting. We recommend the use of 4Ts scoring and more sensible testing and treatment of HIT in ICU patients. Although we could not demonstrate the statistical association between morbid obesity and false positive anti-PF4 Ab, our study might have been underpowered by low subgroup population of such patients. We propose further studies about HIT testing and treatment to include morbidly obese patients as a separate sub-group. Disclosures No relevant conflicts of interest to declare.
