RESUMO
BACKGROUND: Dexamethasone usually recommended for patients with severe coronavirus disease 2019 (COVID-19) to reduce short-term mortality. However, it is uncertain if another corticosteroid, such as methylprednisolone, may be utilized to obtain better clinical outcome. This study assessed dexamethasone's clinical and safety outcomes compared to methylprednisolone. METHODS: A multicenter, retrospective cohort study was conducted between March 01, 2020, and July 31, 2021. It included adult COVID-19 patients who were initiated on either dexamethasone or methylprednisolone therapy within 24 h of intensive care unit (ICU) admission. The primary outcome was the progression of multiple organ dysfunction score (MODS) on day three of ICU admission. Propensity score (PS) matching was used (1:3 ratio) based on the patient's age and MODS within 24 h of ICU admission. RESULTS: After Propensity Score (PS) matching, 264 patients were included; 198 received dexamethasone, while 66 patients received methylprednisolone within 24 h of ICU admission. In regression analysis, patients who received methylprednisolone had a higher MODS on day three of ICU admission than those who received dexamethasone (beta coefficient: 0.17 (95% CI 0.02, 0.32), P = 0.03). Moreover, hospital-acquired infection was higher in the methylprednisolone group (OR 2.17, 95% CI 1.01, 4.66; p = 0.04). On the other hand, the 30-day and the in-hospital mortality were not statistically significant different between the two groups. CONCLUSION: Dexamethasone showed a lower MODS on day three of ICU admission compared to methylprednisolone, with no statistically significant difference in mortality.

BACKGROUND: Given the grave ethical tension and dilemmas posed continuously which are aggravated in the intensive care unit context and its related caregiving provision, combined with their impact on critical care nurses' job satisfaction and work-related risks, exploring and analyzing these tensions and conflicts is crucial. This study was conducted to examine the relationship between perceived ethical work climate and problems among critical care nurses in addition to exploring their perspectives on the ethical work climates while caring for patients with infectious diseases. DESIGN AND METHOD: A mixed-method research design was used to conduct this study among 635 participants, comprising 170 from Egypt, 144 from Jordan, 161 from Saudi Arabia, and 160 from the United Arab Emirates. Online or paper-based survey forms were distributed to all eligible critical care nurses who agreed to take part in the study. The survey contained both quantitative and qualitative data that were analyzed separately and integrated during the discussion. The study was reported following the STROBE guidelines. FINDINGS: The overall ethical work climate was fairly good and was significantly associated with ICU nurses' personal and professional characteristics. The findings also identified three main themes: (1) an ethical sense of failure, (2) environmental condemnation, and (3) an instant action plan for resolving ethical conflicts. CONCLUSIONS: ICU nurses perceived that ICU ethical climate was fairly good. The results indicated that ICU nurses generally had a relatively fair perception of the ethical work climate, with implications for addressing ethical issues and conflicts in various settings. IMPACT: Mentorship and/or close supervision concerning ethical resilience, consultation, and decision-making is crucial in the ICU milieu. Metacognitive strategies to reinforce problem-solving and decision-making ICU nurses' skills could help them overcome the different ethical challenges. Adequate resources, teamwork, and organizational support are promising tactics to improve ICU nurses' ethical skills. TRIAL REGISTRATION: Not applicable.
RESUMO
Backgrounds: Ketamine possesses analgesia, anti-inflammation, anticonvulsant, and neuroprotection properties. However, the evidence that supports its use in mechanically ventilated critically ill patients with COVID-19 is insufficient. The study's goal was to assess ketamine's effectiveness and safety in critically ill, mechanically ventilated (MV) patients with COVID-19. Methods: Adult critically ill patients with COVID-19 were included in a multicenter retrospective-prospective cohort study. Patients admitted between March 1, 2020, and July 31, 2021, to five ICUs in Saudi Arabia were included. Eligible patients who required MV within 24 hours of ICU admission were divided into two sub-cohort groups based on their use of ketamine (Control vs. Ketamine). The primary outcome was the length of stay (LOS) in the hospital. P/F ratio differences, lactic acid normalization, MV duration, and mortality were considered secondary outcomes. Propensity score (PS) matching was used (1:2 ratio) based on the selected criteria. Results: In total, 1,130 patients met the eligibility criteria. Among these, 1036 patients (91.7 %) were in the control group, whereas 94 patients (8.3 %) received ketamine. The total number of patients after PS matching, was 264 patients, including 88 patients (33.3 %) who received ketamine. The ketamine group's LOS was significantly lower (beta coefficient (95 % CI): -0.26 (-0.45, -0.07), P = 0.008). Furthermore, the PaO2/FiO2 ratio significantly improved 24 hours after the start of ketamine treatment compared to the pre-treatment period (6 hours) (124.9 (92.1, 184.5) vs. 106 (73.1, 129.3; P = 0.002). Additionally, the ketamine group had a substantially shorter mean time for lactic acid normalization (beta coefficient (95 % CI): -1.55 (-2.42, -0.69), P 0.01). However, there were no significant differences in the duration of MV or mortality. Conclusions: Ketamine-based sedation was associated with lower hospital LOS and faster lactic acid normalization but no mortality benefits in critically ill patients with COVID-19. Thus, larger prospective studies are recommended to assess the safety and effectiveness of ketamine as a sedative in critically ill adult patients.
RESUMO
Background: Tocilizumab (TCZ) has been proposed as potential rescue therapy for severe COVID-19. No previous study has primarily assessed the role of TCZ in preventing severe COVID-19-related multiorgan dysfunction. Hence, this multicenter cohort study aimed to evaluate the effectiveness of TCZ early use versus standard of care in preventing severe COVID-19-related multiorgan dysfunction in COVID-19 critically ill patients during intensive care unit (ICU) stay. Methods: A multicenter, retrospective cohort study includes critically ill adult patients with COVID-19 admitted to the ICUs. Patients were categorized into two groups, the treatment group includes patients who received early TCZ therapy within 24â hours of ICU admission and the control group includes patients who received standard of care. The primary outcome was the multiorgan dysfunction on day three of the ICU admission. The secondary outcomes were 30-day, and in-hospital mortality, ventilator-free days, hospital length of stay (LOS), ICU LOS, and ICU-related complications. Results: After propensity score matching, 300 patients were included in the analysis based on predefined criteria with a ratio of 1:2. Patients who received TCZ had lower multiorgan dysfunction score on day three of ICU admission compared to the control group (beta coefficient: -0.13, 95% CI: -0.26, -0.01, P-value = 0.04). Moreover, respiratory failure requiring MV was statistically significantly lower in patients who received early TCZ compared to the control group (OR 0.52; 95% CI 0.31, 0.91, P-value = 0.02). The 30-day and in-hospital mortality were significantly lower in patients who received TCZ than those who did not (HR 0.56; 95% CI 0.37, 0.85, P-value = 0 .006 and HR 0.54; 95% CI 0.36, 0.82, P-value = 0.003, respectively). Conclusion: In addition to the mortality benefits associated with early TCZ use within 24â hours of ICU admission, the use of TCZ was associated with a significantly lower multiorgan dysfunction score on day three of ICU admission in critically ill patients with COVID-19.

OBJECTIVE: To characterise the current approach to sedation, analgesia, iatrogenic withdrawal syndrome and delirium in paediatric cardiac ICUs. DESIGN: A convenience sample survey of practitioners at institutions participating in the Pediatric Cardiac Critical Care Consortium conducted from September to December 2020. SETTING: Paediatric cardiac ICUs. MEASUREMENTS AND MAIN RESULTS: Survey responses were received from 33 of 42 institutions contacted. Screening for pain and agitation occurs commonly and frequently. A minority of responding centres (39%) have a written analgesia management protocol/guideline. A minority (42%) of centres have a written protocol for sedation. Screening for withdrawal occurs commonly, although triggers for withdrawal screening vary. Only 42% of respondents have written protocols for withdrawal management. Screening for delirium occurs "always" in 46% of responding centres, "sometimes" in 36% of centres and "never" 18%. Nine participating centres (27%) have written protocols for delirium management. CONCLUSIONS: Our survey identified that most responding paediatric cardiac ICUs lack a standardised approach to the management of analgesia, sedation, iatrogenic withdrawal, and delirium. Screening for pain and agitation occurs regularly, while screening for withdrawal occurs fairly frequently, and screening for delirium is notably less consistent. Only a minority of centres use written protocols or guidelines for the management of these problems. We believe that this represents an opportunity to significantly improve patient care within the paediatric cardiac ICU.

The objective of this qualitative assessment, utilising the constant comparative method, was to identify satisfiers and dissatisfiers that influence paediatric cardiac ICU nurse retention and recognise areas for improvement. Interviews for this study were performed in a single, large academic children's hospital from March of 2020 through July of 2020. Each bedside paediatric cardiac ICU nurse underwent a single semi-structured interview. Among 12 interviews, four satisfiers were identified: paediatric cardiac ICU patient population, paediatric cardiac ICU care team, personal accomplishment, and respect. Four dissatisfiers were identified: moral distress, fear, poor team dynamics, and disrespect. Through this process of inquiry, grounded theory was developed regarding strategies to improve paediatric cardiac ICU nurse retention. Tactics outlined here should be used to support retention in the unique environment of the paediatric cardiac ICU.

Chlorine-containing disinfectants are widely used in hospitals to prevent hospital-acquired severe acute respiratory syndrome coronavirus 2 infection. Meanwhile, ventilation is a simple but effective means to maintain clean air. It is essential to explore the exposure level and health effects of coronavirus disease 2019 patients' inhalation exposure to by-products of chloride-containing disinfectants under frequent surface disinfection and understand the role of ventilation in mitigating subsequent airway damage. We determined ventilation dilution performance and indoor air quality of two intensive care unit wards of the largest temporary hospital constructed in China, Leishenshan Hospital. The chloride inhalation exposure levels, and health risks indicated by interleukin-6 and D-dimer test results of 32 patients were analysed. The mean ± standard deviation values of the outdoor air change rate in the two intensive care unit wards were 8.8 ± 1.5 h-1 (Intensive care unit 1) and 4.1 ± 1.4 h-1 (Intensive care unit 2). The median carbon dioxide and fine particulate matter concentrations were 480 ppm and 19 µg/m3 for intensive care unit 1, and 567 ppm and 21 µg/m3 for intensive care unit 2, all of which were around the average levels of those in permanent hospitals (579 ppm and 21 µg/m3). Of these patients, the median (lower quartile, upper quartile) chloride exposure time and calculated dose were 26.66 (2.89, 57.21) h and 0.357 (0.008, 1.317) mg, respectively. A statistically significant positive correlation was observed between interleukin-6 and D-dimer concentrations. To conclude, ventilation helped maintain ward air cleanliness and health risks were not observed.
RESUMO
BACKGROUND: Spinal fracture is a common traumatic condition in orthopaedics, accounting for 5%-6% of total body fractures, and is a high-risk factor for venous thromboembolism (VTE), which seriously affects patient prognosis. AIM: The aim of this study was to determine the impact of VTE prophylaxis on the prognosis of patients with spinal fractures in intensive care units (ICUs) and to provide a scientific basis for clinical treatment and nursing. DESIGN: A retrospective study of patients with spinal fractures from the multicenter eICU Collaborative Research Database. METHOD: The outcomes of this study were ICU mortality and in-hospital mortality. Patients were divided into the VTE prophylaxis (VP) and no VTE prophylaxis (NVP) groups according to whether they had undergone VTE prophylaxis during their ICU admission. The association between groups and outcomes were analysed using Kaplan-Meier (KM) survival curve, log-rank test and the Cox proportional-hazards regression model. RESULTS: This study included 1146 patients with spinal fractures: 330 in the VP group and 816 in the NVP group. KM survival curves and log-rank tests revealed that both ICU and in-hospital survival probabilities in the VP group were significantly higher than in the NVP group. After the Cox model was adjusted for all covariates, the hazard ratio for ICU mortality in the VP group was 0.38 (0.19-0.75); the corresponding value for in-hospital mortality in the VP group was 0.38 (0.21-0.68). CONCLUSIONS: VTE prophylaxis is associated with reduced ICU and in-hospital mortality in patients with spinal fractures in ICUs. More research is necessary to further define specific strategies and optimal timing for VTE prophylaxis. RELEVANCE TO CLINICAL PRACTICE: This study provides the basis that VTE prophylaxis may be associated with improved prognosis in patients with spinal fractures in ICUs. In clinical practice, an appropriate modality should be selected for VTE prophylaxis in such patients.
RESUMO
BACKGROUND: Studies of the respiratory tract microbiome primarily focus on airway and lung microbial diversity, but it is still unclear how these microbial communities may be affected by intubation and long periods in intensive care units (ICU), an aspect that today could aid in the understanding of COVID19 progression and disease severity. This study aimed to explore and characterize the endotracheal tube (ETT) microbiome by analyzing ETT-associated microbial communities. METHODS: This descriptive study was carried out on adult patients subjected to invasive mechanical ventilation from 2 to 21 days. ETT samples were obtained from 115 patients from ICU units in two hospitals. Bacteria isolated from endotracheal tubes belonging to the ESKAPE group were analyzed for biofilm formation using crystal violet quantification. Microbial profiles were obtained using Illumina sequencing of 16S rRNA gene. RESULTS: The ETT microbiome was mainly composed by the phyla Proteobacteria, Firmicutes and Bacteroidetes. Microbiome composition correlated with the ICU in which patients were hospitalized, while intubation time and diagnosis of ventilator-associated pneumonia (VAP) did not show any significant association. CONCLUSION: These results suggest that the ICU environment, or medical practices, could be a key to microbial colonization and have a direct influence on the ETT microbiomes of patients that require mechanical ventilation.

BACKGROUND: Thrombotic events are common in critically ill patients with COVID-19 and have been linked with COVID-19- induced hyperinflammatory state. In addition to anticoagulant effects, heparin and its derivatives have various anti-inflammatory and immunomodulatory properties that may affect patient outcomes. This study compared the effectiveness and safety of prophylactic standard-doses of enoxaparin and unfractionated heparin (UFH) in critically ill patients with COVID-19. METHODS: A multicenter, retrospective cohort study included critically ill adult patients with COVID-19 admitted to the ICU between March 2020 and July 2021. Patients were categorized into two groups based on the type of pharmacological VTE thromboprophylaxis given in fixed doses (Enoxaparin 40 mg SQ every 24 hours versus UFH 5000 Units SQ every 8 hours) throughout their ICU stay. The primary endpoint was all cases of thrombosis. Other endpoints were considered secondary. Propensity score (PS) matching was used to match patients (1:1 ratio) between the two groups based on the predefined criteria. Multivariable logistic, Cox proportional hazards, and negative binomial regression analysis were used as appropriate. RESULTS: A total of 306 patients were eligible based on the eligibility criteria; 130 patients were included after PS matching (1:1 ratio). Patients who received UFH compared to enoxaparin had higher all thrombosis events at crude analysis (18.3% vs. 4.6%; p-value = 0.02 as well in logistic regression analysis (OR: 4.10 (1.05, 15.93); p-value = 0.04). Although there were no significant differences in all bleeding cases and major bleeding between the two groups (OR: 0.40 (0.07, 2.29); p-value = 0.31 and OR: 1.10 (0.14, 8.56); p-value = 0.93, respectively); however, blood transfusion requirement was higher in the UFH group but did not reach statistical significance (OR: 2.98 (0.85, 10.39); p-value = 0.09). The 30-day and in-hospital mortality were similar between the two groups at Cox hazards regression analysis. In contrast, hospital LOS was longer in the UFH group; however, it did not reach the statistically significant difference (beta coefficient: 0.22; 95% CI: -0.03, 0.48; p-value = 0.09). CONCLUSION: Prophylactic enoxaparin use in critically ill patients with COVID-19 may significantly reduce all thrombosis cases with similar bleeding risk compared to UFH.
RESUMO
BACKGROUND: Hospital and ICU structural factors are key factors affecting the quality of care as well as ICU patient outcomes. However, the data from China are scarce. This study was designed to investigate how differences in patient outcomes are associated with differences in hospital and ICU structure variables in China throughout 2019. METHODS: This was a multicenter observational study. Data from a total of 2820 hospitals were collected using the National Clinical Improvement System Data that reports ICU information in China. Data collection consisted of a) information on the hospital and ICU structural factors, including the hospital type, number of beds, staffing, among others, and b) ICU patient outcomes, including the mortality rate as well as the incidence of ventilator-associated pneumonia (VAP), catheter-related bloodstream infections (CRBSIs), and catheter-associated urinary tract infections (CAUTIs). Generalized linear mixed models were used to analyse the association between hospital and ICU structural factors and patient outcomes. RESULTS: The median ICU patient mortality was 8.02% (3.78%, 14.35%), and the incidences of VAP, CRBSI, and CAUTI were 5.58 (1.55, 11.67) per 1000 ventilator days, 0.63 (0, 2.01) per 1000 catheter days, and 1.42 (0.37, 3.40) per 1000 catheter days, respectively. Mortality was significantly lower in public hospitals (ß = - 0.018 (- 0.031, - 0.005), p = 0.006), hospitals with an ICU-to-hospital bed percentage of more than 2% (ß = - 0.027 (- 0.034, -0.019), p < 0.001) and higher in hospitals with a bed-to-nurse ratio of more than 0.5:1 (ß = 0.009 (0.001, 0.017), p = 0.027). The incidence of VAP was lower in public hospitals (ß = - 0.036 (- 0.054, - 0.018), p < 0.001). The incidence of CRBSIs was lower in public hospitals (ß = - 0.008 (- 0.014, - 0.002), p = 0.011) and higher in secondary hospitals (ß = 0.005 (0.001, 0.009), p = 0.010), while the incidence of CAUTIs was higher in secondary hospitals (ß = 0.010 (0.002, 0.018), p = 0.015). CONCLUSION: This study highlights the association between specific ICU structural factors and patient outcomes. Modifying structural factors is a potential opportunity that could improve patient outcomes in ICUs.

BACKGROUND: Inhaled nitric oxide (iNO) is used as rescue therapy in patients with refractory hypoxemia due to severe COVID-19 acute respiratory distress syndrome (ARDS) despite the recommendation against the use of this treatment. To date, the effect of iNO on the clinical outcomes of critically ill COVID-19 patients with moderate-to-severe ARDS remains arguable. Therefore, this study aimed to evaluate the use of iNO in critically ill COVID-19 patients with moderate-to-severe ARDS. METHODS: This multicenter, retrospective cohort study included critically ill adult patients with confirmed COVID-19 treated from March 01, 2020, until July 31, 2021. Eligible patients with moderate-to-severe ARDS were subsequently categorized into two groups based on inhaled nitric oxide (iNO) use throughout their ICU stay. The primary endpoint was the improvement in oxygenation parameters 24 h after iNO use. Other outcomes were considered secondary. Propensity score matching (1:2) was used based on the predefined criteria. RESULTS: A total of 1598 patients were screened, and 815 were included based on the eligibility criteria. Among them, 210 patients were matched based on predefined criteria. Oxygenation parameters (PaO2, FiO2 requirement, P/F ratio, oxygenation index) were significantly improved 24 h after iNO administration within a median of six days of ICU admission. However, the risk of 30-day and in-hospital mortality were found to be similar between the two groups (HR: 1.18; 95% CI: 0.77, 1.82; p = 0.45 and HR: 1.40; 95% CI: 0.94, 2.11; p= 0.10, respectively). On the other hand, ventilator-free days (VFDs) were significantly fewer, and ICU and hospital LOS were significantly longer in the iNO group. In addition, patients who received iNO had higher odds of acute kidney injury (AKI) (OR (95% CI): 2.35 (1.30, 4.26), p value = 0.005) and hospital/ventilator-acquired pneumonia (OR (95% CI): 3.2 (1.76, 5.83), p value = 0.001). CONCLUSION: In critically ill COVID-19 patients with moderate-to-severe ARDS, iNO rescue therapy is associated with improved oxygenation parameters but no mortality benefits. Moreover, iNO use is associated with higher odds of AKI, pneumonia, longer LOS, and fewer VFDs.

BACKGROUND: Aspirin is widely used as a cardioprotective agent due to its antiplatelet and anti-inflammatory properties. The literature has assessed and evaluated its role in hospitalized COVID-19 patients. However, no data are available regarding its role in COVID-19 critically ill patients. This study aimed to evaluate the use of low-dose aspirin (81-100â mg) and its impact on outcomes in critically ill patients with COVID-19. METHOD: A multicenter, retrospective cohort study of all critically ill adult patients with confirmed COVID-19 admitted to intensive care units (ICUs) between March 1, 2020, and March 31, 2021. Eligible patients were classified into two groups based on aspirin use during ICU stay. The primary outcome was in-hospital mortality, and other outcomes were considered secondary. Propensity score matching was used (1:1 ratio) based on the selected criteria. RESULTS: A total of 1033 patients were eligible, and 352 patients were included after propensity score matching. The in-hospital mortality (HR 0.73 [0.56, 0.97], p = 0.03) was lower in patients who received aspirin during stay. Conversely, patients who received aspirin had a higher odds of major bleeding than those in the control group (OR 2.92 [0.91, 9.36], p = 0.07); however, this was not statistically significant. Additionally, subgroup analysis showed a possible mortality benefit for patients who used aspirin therapy prior to hospitalization and continued during ICU stay (HR 0.72 [0.52, 1.01], p = 0.05), but not with the new initiation of aspirin (HR 1.22 [0.68, 2.20], p = 0.50). CONCLUSION: Continuation of aspirin therapy during ICU stay in critically ill patients with COVID-19 who were receiving it prior to ICU admission may have a mortality benefit; nevertheless, it may be associated with an increased risk of significant bleeding. Appropriate evaluation for safety versus benefits of utilizing aspirin therapy during ICU stay in COVID19 critically ill patients is highly recommended.

Oxygen supplementation is one of the most common interventions in critically ill patients. Despite over a century of data suggesting both beneficial and detrimental effects of supplemental oxygen, optimal arterial oxygenation targets in adult patients remain unclear. Laboratory animal studies have consistently showed that exposure to a high FiO2 causes respiratory failure and early death. Human autopsy studies from the 1960s purported to provide histologic evidence of pulmonary oxygen toxicity in the form of diffuse alveolar damage. However, concomitant ventilator-induced lung injury and/or other causes of acute lung injury may explain these findings. Although some observational studies in general populations of critically adults showed higher mortality in association with higher oxygen exposures, this finding has not been consistent. For some specific populations, such as those with cardiac arrest, studies have suggested harm from targeting supraphysiologic PaO2 levels. More recently, randomized clinical trials of arterial oxygenation targets in narrower physiologic ranges were conducted in critically ill adult patients. Although two smaller trials came to opposite conclusions, the two largest of these trials showed no differences in clinical outcomes in study groups that received conservative versus liberal oxygen targets, suggesting that either strategy is reasonable. It is possible that some strategies are of benefit in some subpopulations, and this remains an important ongoing area of research. Because of the ubiquity of oxygen supplementation in critically ill adults, even small treatment effects could have a large impact on a global scale.

BACKGROUND: We aimed to assess the current nutritional practices in postoperative patients with Congenital Heart Disease. METHODS: Cross-sectional electronic survey was sent to members of The Pediatric Cardiac Intensive Care Society. MEASUREMENTS AND MAIN RESULTS: In Total, 52 members of the Pediatric Cardiac Intensive Care Society responded to the survey consisting of 14% paediatric intensivist, 53% paediatric cardiac intensivist, and 33% nurse/nurse practitioner with a median of 10 years of experience. There was an even distribution between intensivist (55%) and dietitian or nutritionist (45%) in nutrition management. Ninety-eight percent of respondents report that they would feed patients on inotropic or vasoactive support. Only 27% of respondents reported using indirect calorimetry in calculating resting energy expenditure which is the current gold standard. Academic hospitals compared to non-academic hospital were most likely to report feeding patients within 24 hours postoperative (p = 0.014). Having a feeding protocol was associated with feeding within 24 hours postoperative (p = 0.014) and associated with >50% goal intake by 48 hours postoperative (p = 0.025). CONCLUSIONS: Substantial variation in feeding practice still exists despite the American Society for Parenteral and Enteral Nutrition guidelines from 2017. Report of institutional established feeding protocol was associated with increased early feeding and reaching goal feeds by 48 hours postoperative. Very few centres reported use of indirect calorimetry in postoperative paediatric cardiac intensive care patients and many respondents lacked knowledge about applications in this population. Additional work to determine optimal feeding pathways and assessment of caloric needs in this population is needed.

Intensive care units (ICUs) are busy and noisy areas where patients and professional staff can be exposed to acoustic noise for long periods of time. In many cases, noise levels significantly exceed the levels recommended by the official health organisations. This situation can affect not only patient recovery but also professional staff, making ICUs unhealthy work and treatment environments. To introduce the measures and reduce the acoustic noise in the ICU, acoustic noise levels should first be measured and then appropriately analysed. However, in most studies dealing with this problem, measurements have been performed manually over short periods, leading to limited data being collected. They are usually followed by insufficient analysis, which in turn results in inadequate measures and noise reduction. This paper reviews recent works dealing with the problem of excessively high noise levels in ICUs and proposes a more thorough analysis of measured data both in the time and frequency domains. Applied frequency domain analysis identifies the cyclic behaviour of the measured sound pressure levels (SPLs) and detects the dominant frequency components in the SPL time series. Moreover, statistical analyses are produced to depict the patterns and SPLs to which patients in ICUs are typically exposed during their stay in the ICU. It has been shown that the acoustic environment is very similar every night, while it can vary significantly during the day or evening periods. However, during most of the observed time, recorded SPLs were significantly above the prescribed values, indicating an urgent need for their control and reduction. To effectively tackle this problem, more detailed information about the nature of noise during each of the analysed periods of the day is needed. This issue will be addressed in the continuation of this project.

The health-care system around the world has recognized the importance and usefulness of spirituality in the delivery of care. The goal of this study was to describe nurses' self-perceived ability in providing spiritual care to patients in Intensive Care Units, as well as to look into the relationship between demographic variables and their competencies. The researchers used a descriptive correlation design. There were 106 surveys distributed in total. Two large hospitals in Jouf, Saudi Arabia, had an 83.01% response rate. The self-reported questionnaire was completed by 88 nurses. The majority of nurses said they were capable of providing spiritual care to patients of the Islamic faith. Religions had statistically significant mean Spiritual Care Competency scores. It is critical to have a unified health strategy based on multidisciplinary collaborations to control spiritual care delivery, particularly in Intensive Care Units.
RESUMO
Gastrointestinal dysfunction/failure (GDF) is a common cause of concern in critically ill patients. Although the gut plays an important role in the genesis of organ failure, its exclusion from organ severity scoring systems has made it challenging for intensivists to score it sufficiently at the bedside. We aimed to survey intensive care specialists about their perceptions, attitudes, and approaches towards the assessment of the gut in Australia and New Zealand intensive care units (ICUs). An electronic (online) questionnaire was used to survey intensive care specialists from the Australia and New Zealand Intensive Care Society (ANZICS). The survey comprised 10 questions focused on four key areas: (i) the extent of the problem with GDF in ICUs, (ii) the use and reliability of the current gut scoring tools, (iii) personal approaches and practices associated with GDF assessment, and (4) potential value of a novel GDF scoring system and its incorporation into an organ severity score. Our results showed that GDF was a significant concern amongst ICUs in Australia and New Zealand intensivists (84%; 66/79), with a small number of participants (14%; 3/79) using a gut scoring tool in their ICUs. Despite this, we have no established objective scoring tool for its assessment. The survey highlighted the need for developing a novel scoring tool to assess the gut was considered important amongst majority of the intensivists (92%; 72/78), which would prove useful in clinical practice and potentially lead to incorporation into an organ severity score in the future.

INTRODUCTION: The risk of mortality in patients with COVID-19 was found to be significantly higher in patients who experienced thromboembolic events. Thus, several guidelines recommend using prophylactic anticoagulants in all COVID-19 hospitalized patients. However, there is uncertainty about the appropriate dosing regimen and safety of anticoagulation in critically ill patients with COVID-19. Thus, this study aims to compare the effectiveness and safety of standard versus escalated dose pharmacological venous thromboembolism (VTE) prophylaxis in critically ill patients with COVID-19. METHODS: A two-center retrospective cohort study including critically ill patients aged ≥ 18-years with confirmed COVID-19 admitted to the intensive care unit (ICU) at two tertiary hospitals in Saudi Arabia from March 1st, 2020, until January 31st, 2021. Patients who received either Enoxaparin 40 mg daily or Unfractionated heparin 5000 Units three times daily were grouped under the "standard dose VTE prophylaxis and patients who received higher than the standard dose but not as treatment dose were grouped under "escalated VTE prophylaxis dose". The primary outcome was the occurance of thrombotic events, and the secondary outcomes were bleeding, mortality, and other ICU-related complications. RESULTS: A total of 758 patients were screened; 565 patients were included in the study. We matched 352 patients using propensity score matching (1:1). In patients who received escalated dose pharmacological VTE prophylaxis, any case of thrombosis and VTE were similar between the two groups (OR 1.22;95 %CI 0.52-2.86; P = 0.64 and OR 0.75; 95% CI 0.16-3.38; P = 0.70 respectively). However, the odds of minor bleeding was higher in patients who received escalated VTE prophylaxis dose (OR 3.39; 95% CI 1.08-10.61; P = 0.04). There was no difference in the 30-day mortality nor in-hospital mortality between the two groups (HR 1.17;95 %CI0.79-1.73; P = 0.43 and HR 1.08;95 %CI 0.76-1.53; P = 0.83, respectively). CONCLUSION: Escalated-dose pharmacological VTE prophylaxis in critically ill patients with COVID-19 was not associated with thrombosis, or mortality benefits but led to an increased risk of minor bleeding. This study supports previous evidence regarding the optimal dosing VTE pharmacological prophylaxis regimen for critically ill patients with COVID-19.
RESUMO
BACKGROUND: Tocilizumab is an IgG1 class recombinant humanized monoclonal antibody that directly inhibits the IL-6 receptor. Several randomized clinical trials have evaluated its safety and efficacy in patients with coronavirus disease 2019 (COVID-19), and these studies demonstrate conflicting results. Our study aimed to determine the association between tocilizumab treatment and microbial isolation and emergence of multidrug-resistant bacteria in critically ill patients with COVID-19. METHODS: A multicenter retrospective cohort study was conducted at two tertiary government hospitals in Saudi Arabia. All critically ill patients admitted to intensive care units with a positive COVID-19 PCR test between March 1 and December 31, 2020, who met study criteria were included. Patients who received tocilizumab were compared to those who did not receive it. RESULTS: A total of 738 patients who met our inclusion criteria were included in the analysis. Of these, 262 (35.5%) received tocilizumab, and 476 (64.5%) were included in the control group. Patients who received tocilizumab had higher odds for microbial isolation (OR 1.34; 95% CI 0.91-1.94, p = 0.13); however, the difference was not statistically significant. Development of resistant organisms (OR 1.00; 95% CI 0.51-1.98, p = 0.99) or detection of carbapenem-resistant Enterobacteriaceae (CRE) (OR 0.67; 95% CI 0.29-1.54, p = 0.34) was not statistically significant between the two groups. CONCLUSIONS: Tocilizumab use in critically ill patients with COVID-19 is not associated with higher microbial isolation, the emergence of resistant organisms, or the detection of CRE organisms.
