Pneumocystis pneumonia in intensive care: clinical spectrum, prophylaxis patterns, antibiotic treatment delay impact, and role of corticosteroids. A French multicentre prospective cohort study.

PURPOSE: Severe Pneumocystis jirovecii pneumonia (PJP) requiring intensive care has been the subject of few prospective studies. It is unclear whether delayed curative antibiotic therapy may impact survival in these severe forms of PJP. The impact of corticosteroid therapy combined with antibiotics is also unclear. METHODS: This multicentre, prospective observational study involving 49 adult intensive care units (ICUs) in France was designed to evaluate the severity, the clinical spectrum, and outcomes of patients with severe PJP, and to assess the association between delayed curative antibiotic treatment and adjunctive corticosteroid therapy with mortality. RESULTS: We included 158 patients with PJP from September 2020 to August 2022. Their main reason for admission was acute respiratory failure (n = 150, 94.9%). 12% of them received antibiotic prophylaxis for PJP before ICU admission. The ICU, hospital, and 6-month mortality were 31.6%, 35.4%, and 40.5%, respectively. Using time-to-event analysis with a propensity score-based inverse probability of treatment weighting, the initiation of curative antibiotic treatment after 96 h of ICU admission was associated with faster occurrence of death [time ratio: 6.75; 95% confidence interval (95% CI): 1.48-30.82; P = 0.014]. The use of corticosteroids for PJP was associated with faster occurrence of death (time ratio: 2.48; 95% CI 1.01-6.08; P = 0.048). CONCLUSION: This study showed that few patients with PJP admitted to intensive care received prophylactic antibiotic therapy, that delay in curative antibiotic treatment was common and that both delay in curative antibiotic treatment and adjunctive corticosteroids for PJP were associated with accelerated mortality.

Pneumocystis pneumonia in French intensive care units in 2013-2019: mortality and immunocompromised conditions.

PURPOSE: The recent epidemiology of Pneumocystis pneumonia (PCP) requiring intensive care unit (ICU) admission and the associated spectrum of immunocompromising conditions are poorly described. METHODS: We analyzed all adult PCP cases admitted to French ICUs via the French medical database system (PMSI), over the period from 2013 to 2019. RESULTS: French ICUs admitted a total of 4055 adult patients with PCP. Among all hospitalized PCP cases, the proportion requiring ICU admission increased from 17.8 in 2014 to 21.3% in 2019 (P < 0.001). The incidence of severe PCP rose from 0.85 in 2013 to 1.32/100,000 adult inhabitants in 2019 (P < 0.0001), primarily due to the proportion of HIV-negative patients that increased from 60.6% to 74.4% (P < 0.0001). Meanwhile, the annual number of severe PCP cases among patients with HIV infection remained stable over the years. In-hospital mortality of severe PCP cases was 28.5% in patients with HIV infection and 49.7% in patients without. Multivariable logistic analysis showed that patients with HIV infection had a lower adjusted risk of death than patients without HIV infection (Odds Ratio [OR]: 0.30, 95% confidence interval [95CI]: 0.17-0.55). Comorbidities or conditions strongly associated with hospital mortality included the patient's age, Simplified Acute Physiologic Score II, congestive heart failure, coagulopathy, solid organ cancer, and cirrhosis. A vast array of autoimmune inflammatory diseases affected 19.9% of HIV-negative patients. CONCLUSIONS: The number of PCP cases requiring ICU admission in France has risen sharply. While the yearly count of severe PCP cases in HIV-infected patients has remained steady, this rise predominantly affects cancer patients, with a recent surge observed in patients with autoimmune inflammatory diseases, affecting one in five individuals.

Critically Ill Patients with Visceral Nocardia Infection, France and Belgium, 2004-2023.

We studied 50 patients with invasive nocardiosis treated during 2004-2023 in intensive care centers in France and Belgium. Most (65%) died in the intensive care unit or in the year after admission. Nocardia infections should be included in the differential diagnoses for patients in the intensive care setting.

Barriers to research findings utilization amongst critical care nurses and allied health professionals: An international survey.

OBJECTIVES: To determine the perceived barriers to the implementation of research findings in clinical practice among critical care nurses and allied health professionals. METHODS: A cross-sectional study was conducted using an online questionnaire sent to critical care nurses and allied health professionals in French-speaking countries. The primary objective was the identification and grading of perceived barriers to implementation of research findings into clinical practice, using a previously validated tool (French version of the BARRIERS scale). The scale is divided into 4 dimensions, each containing 6 to 7 questions to be answered using a 4-point Likert scale (1: no barrier, 4: great barrier). Descriptive statistics were performed and weighted score per dimensions were compared. Univariate and multivariate linear regressions were performed to identify factors associated with the total score by dimension. RESULTS: A total of 994 nurses and allied health professionals (85.1 % of ICU nurses) from 5 countries (71.8 % from France) responded to the survey. Main reported barriers to research findings utilization were "Statistical analyses are not understandable" (54.5 %), "Research articles are not readily available" (54.3 %), and "Implications for practice are not made clear" (54.2 %). Weighted scores differed between dimensions, with the "communication" and "organization" dimensions being the greatest barriers (median [IQR]: 2.3 [1.8-2.7] and 2.0 [1.6-2.4], while the "adopter" and "innovation" dimensions having lower scores (1.5 [1.2-1.8] and 1.5 [1.0-1.8] (all pairwise comparisons p-value < 0.0001, except for the adopter vs. innovation comparison, p > 0.05). CONCLUSIONS: Accessibility and understanding of research results seem to be the main barriers to research utilization in practice by respondents. A large number of the reported barriers could be overcome through education and organizational change. IMPLICATIONS FOR PRACTICE: Promoting a research culture among nurses and allied health professionals is an issue that needs investment. This should include training in critical reading of scientific articles and statistics.

Risk factors for poor performance in finger cuff non-invasive monitoring of arterial pressure: A prospective multicenter study.

BACKGROUND: Compared to the invasive technique, non-invasive monitoring of arterial pressure favors easier and faster implementation while potentially sacrificing some reliability. This may be particularly true for the Clearsight™ system (Edwards Lifesciences), which enables continuous monitoring. We evaluated the risk factors for its poor performance. METHODS: Patients with an arterial catheter and stable mean arterial pressure (MAP) over a 5-min period were included. Six pairs of invasive and Clearsight measurements of MAP were collected and the bias between the two techniques was calculated. Poor performance of the Clearsight™ system was defined as either a failure to measure and display MAP or displaying an erroneous MAP (individual bias > 5 mmHg). Fingertip perfusion was assessed using the plethysmographic perfusion index (PI) and the capillary refill time (CRT). RESULTS: Among 152 ICU patients (MAP of 81 ± 14 mmHg, norepinephrine in 78 [51%]), 78 (51%) experienced a poor performance of the Clearsight™ system: failure to display MAP in 19 (13%) patients, and erroneous value displayed in 59 (44%). In multivariate analysis, PI ≤ 0.85% (adjusted odds ratio [aOR] = 2.94 [95% confidence interval (95%CI):1.34;6.45]), CRT > 4 s (aOR = 5.28 [95%CI 1.39;20.05]), and the presence of hand edema (aOR = 2.06 [95%CI 1.01;4.21]) were associated with a higher likelihood of poor performance. Cardiac arrhythmia (aOR = 1.39 [95%CI 0.64;3.02]) and other tested variables were not associated with poor performance. CONCLUSIONS: Half of the included patients exhibited poor Clearsight™ system performance. Our results caution against using finger cuff arterial pressure monitoring in patients with low PI (≤0.85%), protracted CRT (>4 s), or hand edema.

Noninvasive Monitoring of Arterial Pressure: Finger or Lower Leg As Alternatives to the Upper Arm: A Prospective Study in Three ICUs.

OBJECTIVES: When the upper arm is inaccessible for measurements of arterial pressure (AP), the best alternative site is unknown. We performed a between-site comparison of the agreement between invasive and noninvasive readings of AP taken at the lower leg, the finger, and the upper arm. The risk associated with measurement errors and the trending ability were also assessed. DESIGN: Prospective observational study. SETTING: Three ICUs. PATIENTS: Patients having an arterial catheter and an arm circumference less than 42 cm. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Three triplicates of AP measurements were collected via an arterial catheter (reference AP), a finger cuff system (ClearSight; Edward Lifesciences, Irvine, CA), and an oscillometric cuff (at the lower leg then the upper arm). Trending ability was assessed through an additional set of measurements after a cardiovascular intervention. The default bed backrest angle was respected. Failure to measure and display AP occurred in 19 patients (13%) at the finger, never at other sites. In 130 patients analyzed, the agreement between noninvasive and invasive readings was worse at the lower leg than that observed at the upper arm or the finger (for mean AP, bias ± sd of 6.0 ± 15.8 vs 3.6 ± 7.1 and 0.1 ± 7.4 mm Hg, respectively; p < 0.05), yielding a higher frequency of error-associated clinical risk (no risk for 64% vs 84% and 86% of measurements, respectively, p < 0.0001). According to the International Organization for Standardization (ISO) 81060-2:2018 standard, mean AP measurements were reliable at the upper arm and the finger, not the lower leg. In 33 patients reassessed after a cardiovascular intervention, both the concordance rate for change in mean AP and the ability to detect a therapy-induced significant change were good and similar at the three sites. CONCLUSIONS: As compared with lower leg measurements of AP, finger measurements were, when possible, a preferable alternative to upper arm ones.

The accuracy of intensive care nurses' interpretation of chest radiographs to recognise misplacement of endotracheal and nasogastric tubes after a single training session and comparison with residents' interpretation.

BACKGROUND: Misplacements of endotracheal and nasogastric tubes are frequent encounters in critically ill patients. OBJECTIVES: The purpose of this study was to assess the effectiveness of a single standardised training session on the ability of intensive care registered nurses (RNs) to recognise the misplacement of endotracheal and nasogastric tubes on bedside chest radiographs of patients in intensive care units (ICUs). METHODS: In eight French ICUs, RNs received a 110-min standardised teaching on the position of endotracheal and nasogastric tubes on chest radiographs. Their knowledge was evaluated within the subsequent weeks. For 20 chest radiographs, each with an endotracheal and nasogastric tube, RNs had to indicate whether each tube was in the proper or incorrect position. Training success was defined as >90% for the lower bound of the 95% confidence interval (95% CI) of the mean correct response rate (CRR). Residents of the participating ICUs underwent the same evaluation (without prior specific training). RESULTS: In total, 181 RNs were trained and evaluated and 110 residents were evaluated. The global mean CRR for RNs was 84.6% (95% CI: 83.3-85.9), significantly higher than for residents (81.4% [95% CI: 79.7-83.2]) (P < 0.0001). The mean CRR for RNs and residents was 95.9% (93.9-98.0) and 97.0% (94.7-99.3) for misplaced nasogastric tubes (P = 0.54), 86.8% (85.2-88.5) and 82.6% (79.4-85.7) (P = 0.07) for nasogastric tubes in the correct position, 86.6% (83.8-89.3) and 62.7% (57.9-67.5) for misplaced endotracheal tubes (P < 0.0001), and 79.1% (76.6-81.6) and 84.7% (82.1-87.2) for endotracheal tubes in the correct position (P = 0.01), respectively. CONCLUSIONS: The ability of trained RNs to detect tube misplacement did not reach the predetermined arbitrary level, indicating training success. Their mean CRR was higher than that for residents and was considered satisfactory for detecting misplaced nasogastric tubes. This finding is encouraging but insufficient to ensure patient safety. Transferring responsibility for reading radiographs to detect the misplacement of endotracheal tubes to intensive care RNs will need a more advanced or more in-depth teaching method.

Hydrocortisone in Severe Community-Acquired Pneumonia.

BACKGROUND: Whether the antiinflammatory and immunomodulatory effects of glucocorticoids may decrease mortality among patients with severe community-acquired pneumonia is unclear. METHODS: In this phase 3, multicenter, double-blind, randomized, controlled trial, we assigned adults who had been admitted to the intensive care unit (ICU) for severe community-acquired pneumonia to receive intravenous hydrocortisone (200 mg daily for either 4 or 7 days as determined by clinical improvement, followed by tapering for a total of 8 or 14 days) or to receive placebo. All the patients received standard therapy, including antibiotics and supportive care. The primary outcome was death at 28 days. RESULTS: A total of 800 patients had undergone randomization when the trial was stopped after the second planned interim analysis. Data from 795 patients were analyzed. By day 28, death had occurred in 25 of 400 patients (6.2%; 95% confidence interval [CI], 3.9 to 8.6) in the hydrocortisone group and in 47 of 395 patients (11.9%; 95% CI, 8.7 to 15.1) in the placebo group (absolute difference, -5.6 percentage points; 95% CI, -9.6 to -1.7; P = 0.006). Among the patients who were not undergoing mechanical ventilation at baseline, endotracheal intubation was performed in 40 of 222 (18.0%) in the hydrocortisone group and in 65 of 220 (29.5%) in the placebo group (hazard ratio, 0.59; 95% CI, 0.40 to 0.86). Among the patients who were not receiving vasopressors at baseline, such therapy was initiated by day 28 in 55 of 359 (15.3%) of the hydrocortisone group and in 86 of 344 (25.0%) in the placebo group (hazard ratio, 0.59; 95% CI, 0.43 to 0.82). The frequencies of hospital-acquired infections and gastrointestinal bleeding were similar in the two groups; patients in the hydrocortisone group received higher daily doses of insulin during the first week of treatment. CONCLUSIONS: Among patients with severe community-acquired pneumonia being treated in the ICU, those who received hydrocortisone had a lower risk of death by day 28 than those who received placebo.

Relying on pulse oximetry to avoid hypoxaemia and hyperoxia: A multicentre prospective cohort study in patients with circulatory failure.

PURPOSE: The purpose of this study was to assess the predictive performance of pulse oximetry (SpO2) to rule out hypoxaemia and hyperoxia in critically ill patients. METHODS: SpO2, arterial oxygenation (SaO2), and arterial partial pressure of oxygen (PaO2) were prospectively and simultaneously measured every 6 h during the first 24 h of intensive care unit admission in a multicentre cohort of critically ill patients suffering acute circulatory failure. Likelihood ratios associated with different cutoff values of SpO2 to rule out hypoxaemia (SaO2 < 90% or PaO2 < 60 mmHg) or hyperoxia (SaO2 > 95% or PaO2 > 100 mmHg) and post-test probabilities were calculated. Mean bias between SpO2 and SaO2 and agreement interval were calculated. Area under the receiver operating characteristics associated with SpO2 to predict different threshold values of SaO2 and PaO2 were calculated. RESULTS: Five hundred seventy-one patients (mean [standard deviation] Simplified Acute Physiology Score II: 58.7 [20.1]; mechanically ventilated 75.6%) with 2643 available SaO2 and PaO2 samples and corresponding 2643 SpO2 values were analysed. Mean bias between SpO2 and SaO2 was 1.1%, and its agreement interval ranged from -8.2 to +11.1%. SpO2 cutoff values of 88%, 90%, and 92% left the possibility that 8%-13% of patients had hypoxaemia. SpO2 < 95% left the possibility that 31% of patients had hyperoxia. All calculated areas under the receiver operating characteristics showed a lower limit of their 95% confidence interval below 0.85 CONCLUSION: In this cohort of patients with circulatory failure, SpO2 had poor discriminative ability to rule out hypoxaemia and hyperoxia. Overconfidence upon SpO2 monitoring may be dangerous.

Comparison of high-flow nasal therapy, noninvasive ventilation, and continuous positive airway pressure on outcomes in critically ill patients admitted for COVID-19 with acute respiratory failure.

BACKGROUND: The optimal first-line noninvasive respiratory support (NIRS) to improve outcome in patients affected by COVID-19 pneumonia admitted to ICU is still debated. METHODS: We conducted a retrospective study in seven French ICUs, including all adults admitted between July and December 2020 with documented SARS-CoV-2 acute respiratory failure (PaO2/FiO2<300 mmHg), and treated with either high-flow nasal therapy (HFNT) alone, noninvasive ventilation alone or in combination with HFNT (NIV), or continuous positive airway pressure alone or in combination with HFNT (CPAP). The primary outcome was NIRS failure at day 28, defined as the need for endotracheal intubation (ETI) or death without ETI. RESULTS: Among the 355 patients included, 160 (45%) were treated with HFNT alone, 115 (32%) with NIV and 80 (23%) with CPAP. The primary outcome occurred in 65 (41%), 69 (60%), and 25 (31%) patients among those treated with HFNT alone, NIV, and CPAP, respectively (P<0.001). After univariate analysis, patients treated with CPAP had a trend for a lower incidence of the primary outcome, whereas patients treated with NIV had a significant higher incidence of the primary outcome, both compared to those treated with HFNT alone (unadjusted Hazard ratio 0.67; 95% CI [0.42-1.06], and 1.58; 95% CI [1.12-2.22]; P=0.09 and 0.008, respectively). CONCLUSIONS: Among ICU patients admitted for severe COVID-19 pneumonia and managed with NIRS, the outcome seems to differ according to the initial chosen strategy. Prospective randomized controlled studies are warranted to identify the optimal strategy.

Management and outcomes of pregnant women admitted to intensive care unit for severe pneumonia related to SARS-CoV-2 infection: the multicenter and international COVIDPREG study.

PURPOSE: Management and outcomes of pregnant women with coronavirus disease 2019 (COVID-19) admitted to intensive care unit (ICU) remain to be investigated. METHODS: A retrospective multicenter study conducted in 32 ICUs in France, Belgium and Switzerland. Maternal management as well as maternal and neonatal outcomes were reported. RESULTS: Among the 187 pregnant women with COVID-19 (33 ± 6 years old and 28 ± 7 weeks' gestation), 76 (41%) were obese, 12 (6%) had diabetes mellitus and 66 (35%) had pregnancy-related complications. Standard oxygenation, high-flow nasal oxygen therapy (HFNO) and non-invasive ventilation (NIV) were used as the only oxygenation technique in 41 (22%), 55 (29%) and 18 (10%) patients, respectively, and 73 (39%) were intubated. Overall, 72 (39%) patients required several oxygenation techniques and 15 (8%) required venovenous extracorporeal membrane oxygenation. Corticosteroids and tocilizumab were administered in 157 (84%) and 25 (13%) patients, respectively. Awake prone positioning or prone positioning was performed in 49 (26%) patients. In multivariate analysis, risk factors for intubation were obesity (cause-specific hazard ratio (CSH) 2.00, 95% CI (1.05-3.80), p = 0.03), term of pregnancy (CSH 1.07, 95% CI (1.02-1.10), per + 1 week gestation, p = 0.01), extent of computed tomography (CT) scan abnormalities > 50% (CSH 2.69, 95% CI (1.30-5.60), p < 0.01) and NIV use (CSH 2.06, 95% CI (1.09-3.90), p = 0.03). Delivery was required during ICU stay in 70 (37%) patients, mainly due to maternal respiratory worsening, and improved the driving pressure and oxygenation. Maternal and fetal/neonatal mortality rates were 1% and 4%, respectively. The rate of maternal and/or neonatal complications increased with the invasiveness of maternal respiratory support. CONCLUSION: In ICU, corticosteroids, tocilizumab and prone positioning were used in few pregnant women with COVID-19. Over a third of patients were intubated and delivery improved the driving pressure.

Sensitivity and specificity of heat and moisture exchange filters sampling for SARS-CoV-2 detection in mechanically ventilated COVID-19 patients.

We assessed the sensitivity and specificity of SARS-CoV-2 detection by polymerase chain reaction in heat and moisture exchange filters (HMEF) in mechanically ventilated COVID-19 patients. We showed that testing HMEF might obviate the need for a tracheal sample to affirm that a patient is not ready to end isolation.

Effect of a Musical Intervention During the Implantation of a Central Venous Catheter or a Dialysis Catheter in the Intensive Care Unit: A Prospective Randomized Pilot Study.

BACKGROUND: Listening to music may reduce anxiety during medical procedures. However, the magnitude of any effect may differ with respect to patient and procedure. We evaluated the effect of a musical intervention on patient anxiety during a central venous catheter or dialysis catheter implantation in an intensive care unit. METHODS: A prospective single-center controlled open-label 2-arm randomized trial was conducted in a medical intensive care unit (ICU) from February 2018 to February 2019. Patients undergoing central venous catheterization were randomized to listening to music or not during the procedure. Patients randomized to music listened to the Music Care application via headphones. The primary outcome was the change in anxiety assessed on a 100-mm Visual Analogue Scale between the beginning and end of the catheterization procedure. Secondary outcomes included postprocedural pain. RESULTS: We included 37 patients in the musical intervention group and 35 in the standard care group. The primary reasons for intensive care unit admission were the need for a central catheter for chemotherapy for hematologic malignancy and sepsis and/or septic shock in both groups. Postprocedural anxiety and pain assessments were missing in 1 (2.7%) and 4 (11.4%) patients in the intervention and standard care groups. We found no between-group difference in change in anxiety score: median -1 (interquartile range, -3 to 0) vs 0 (-3 to 0) in the musical intervention and standard care groups (median difference, -1 [-2 to 0]) (P = .24). Postprocedural pain score did not differ between the groups: median 0 (0-2) and 0 (0-3.75) in the musical intervention and standard care groups (median difference, -0 [0-0]) (P = .40). To account for missing outcome assessments, sensitivity analyses were performed using 2 extreme scenarios, one favoring the standard care group (scenario 1) and the other favoring the intervention group (scenario 2). In either scenario, change in anxiety score did not differ between the intervention and standard care groups: -1 (-3 to 0) vs 0 (-4 to 0) (P = .88) in scenario 1 and -1 (-3 to 0) vs 0 (-2.75 to 1) (P = .07) in scenario 2. CONCLUSIONS: In this first randomized pilot study of musical intervention for central venous catheterization in awake patients in the intensive care unit, the musical intervention did not reduce patients' anxiety as compared with usual care.

Menstrual Toxic Shock Syndrome: A French Nationwide Multicenter Retrospective Study.

BACKGROUND: Studies describing the clinical features and short-term prognosis of patients admitted to the intensive care unit (ICU) for menstrual toxic shock syndrome (m-TSS) are lacking. METHODS: This was a multicenter retrospective cohort study of patients with a clinical diagnosis of m-TSS admitted between 1 January 2005 and 31 December 2020 in 43 French pediatric (n = 7) or adult (n = 36) ICUs. The aim of the study was to describe the clinical features and short-term prognosis, as well as to assess the 2011 Centers for Disease and Control (CDC) diagnostic criteria, in critically ill patients with m-TSS. RESULTS: In total, 102 patients with m-TSS (median age, 18 years; interquartile range, 16-24 years) were admitted to 1 of the participating ICUs. All blood cultures (n = 102) were sterile. Methicillin-sensitive Staphylococcus aureus grew from 92 of 96 vaginal samples. Screening for superantigenic toxin gene sequences was performed for 76 of the 92 vaginal samples positive for S. aureus (83%), and toxic shock syndrome toxin 1 was isolated from 66 strains (87%). At ICU admission, no patient met the 2011 CDC criteria for confirmed m-TSS, and only 53 (52%) fulfilled the criteria for probable m-TSS. Eighty-one patients (79%) were treated with antitoxin antibiotic therapy, and 8 (8%) received intravenous immunoglobulins. Eighty-six (84%) patients required vasopressors, and 21 (21%) tracheal intubation. No patient required limb amputation or died in the ICU. CONCLUSIONS: In this large multicenter series of patients included in ICUs for m-TSS, none died or required limb amputation. The CDC criteria should not be used for the clinical diagnosis of m-TSS at ICU admission.

Incidence, clinical characteristics, and outcome after unexpected cardiac arrest among critically ill adults with COVID-19: insight from the multicenter prospective ACICOVID-19 registry.

BACKGROUND: Initial reports have described the poor outcome of unexpected cardiac arrest (CA) in intensive care unit (ICU) among COVID-19 patients in China and the USA. However, there are scarce data on characteristics and outcomes of such CA patients in Europe. METHODS: Prospective registry in 35 French ICUs, including all in-ICU CA in COVID-19 adult patients with cardiopulmonary resuscitation (CPR) attempt. Favorable outcome was defined as modified Rankin scale ranging from 0 to 3 at day 90 after CA. RESULTS: Among the 2425 COVID-19 patients admitted to ICU from March to June 2020, 186 (8%) experienced in-ICU CA, of whom 146/186 (78%) received CPR. Among these 146 patients, 117 (80%) had sustained return of spontaneous circulation, 102 (70%) died in the ICU, including 48 dying within the first day after CA occurrence and 21 after withdrawal of life-sustaining therapy. Most of CA were non-shockable rhythm (90%). At CA occurrence, 132 patients (90%) were mechanically ventilated, 83 (57%) received vasopressors and 75 (51%) had almost three organ failures. Thirty patients (21%) had a favorable outcome. Sepsis-related organ failure assessment score > 9 before CA occurrence was the single parameter constantly associated with unfavorable outcome in multivariate analysis. CONCLUSIONS: In-ICU CA incidence remains high among a large multicenter cohort of French critically ill adults with COVID-19. However, 21% of patients with CPR attempt remained alive at 3 months with good functional status. This contrasts with other recent reports showing poor outcome in such patients. TRIAL REGISTRATION: This study was retrospectively registered in ClinicalTrials.gov (NTC04373759) in April 2020 ( https://www.clinicaltrials.gov/ct2/show/NCT04373759?term=acicovid&draw=2&rank=1 ).

Early versus differed arterial catheterisation in critically ill patients with acute circulatory failure: a multicentre, open-label, pragmatic, randomised, non-inferiority controlled trial: the EVERDAC protocol.

INTRODUCTION: The use of peripheral indwelling arterial catheter for haemodynamic monitoring is widespread in the intensive care unit and is recommended in patients with shock. However, there is no evidence that the arterial catheter could improve patient's outcome, whereas the burden of morbidity generated is significant (pain, thrombosis, infections). We hypothesise that patients with shock may be managed without an arterial catheter. METHODS AND ANALYSIS: The EVERDAC study is an investigator-initiated, pragmatic, multicentre, randomised, controlled, open-label, non-inferiority clinical trial, comparing a less invasive intervention (ie, no arterial catheter insertion until felt absolutely needed, according to predefined safety criteria) or usual care (ie, systematic arterial catheter insertion in the early hours of shock). 1010 patients will be randomised with a 1:1 ratio in two groups according to the strategy. The primary outcome is all-cause mortality by 28 days after inclusion. A health economic analysis will be carried out. ETHICS AND DISSEMINATION: The study has been approved by the Ethics Committee (Comité de Protection des Personnes Île de France V, registration number 61606 CAT 2, 19 july 2018) and patients will be included after informed consent. The results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03680963.

Preemptive ganciclovir for mechanically ventilated patients with cytomegalovirus reactivation.

BACKGROUND: The effect of cytomegalovirus (CMV) reactivation on the length of mechanical ventilation and mortality in immunocompetent ICU patients requiring invasive mechanical ventilation remains controversial. The main objective of this study was to determine whether preemptive intravenous ganciclovir increases the number of ventilator-free days in patients with CMV blood reactivation. METHODS: This double-blind, placebo-controlled, randomized clinical trial involved 19 ICUs in France. Seventy-six adults ≥ 18 years old who had been mechanically ventilated for at least 96 h, expected to remain on mechanical ventilation for ≥ 48 h, and exhibited reactivation of CMV in blood were enrolled between February 5th, 2014, and January 23rd, 2019. Participants were randomized to receive ganciclovir 5 mg/kg bid for 14 days (n = 39) or a matching placebo (n = 37). RESULTS: The primary endpoint was ventilator-free days from randomization to day 60. Prespecified secondary outcomes included day 60 mortality. The trial was stopped for futility based on the results of an interim analysis by the DSMB. The subdistribution hazard ratio for being alive and weaned from mechanical ventilation at day 60 for patients receiving ganciclovir (N = 39) compared with control patients (N = 37) was 1.14 (95% CI from 0.63 to 2.06; P = 0.66). The median [IQR] numbers of ventilator-free days for ganciclovir-treated patients and controls were 10 [0-51] and 0 [0-43] days, respectively (P = 0.46). Mortality at day 60 was 41% in patients in the ganciclovir group and 43% in the placebo group (P = .845). Creatinine levels and blood cells counts did not differ significantly between the two groups. CONCLUSIONS: In patients mechanically ventilated for ≥ 96 h with CMV reactivation in blood, preemptive ganciclovir did not improve the outcome.

Epidural analgesia in ICU chest trauma patients with fractured ribs: retrospective study of pain control and intubation requirements.

BACKGROUND: Nonintubated chest trauma patients with fractured ribs admitted to the intensive care unit (ICU) are at risk for complications and may require invasive ventilation at some point. Effective pain control is essential. We assessed whether epidural analgesia (EA) in patients with fractured ribs who were not intubated at ICU admission decreased the need for invasive mechanical ventilation (IMV). We also looked for risk factors for IMV. STUDY DESIGN AND METHODS: This retrospective, observational, multicenter study conducted in 40 ICUs in France included consecutive patients with three or more fractured ribs who were not intubated at admission between July 2013 and July 2015. RESULTS: Of the 974 study patients, 788 were included in the analysis of intubation predictors. EA was used in 130 (16.5%) patients, and 65 (8.2%) patients required IMV. Factors independently associated with IMV were chronic respiratory disease (P = 0.008), worse SAPS II (P < 0.0001), flail chest (P = 0.02), worse Injury Severity Score (P = 0.0003), higher respiratory rate at admission (P = 0.02), alcohol withdrawal syndrome (P < 0.001), and noninvasive ventilation (P = 0.04). EA was not associated with decreases in IMV requirements, median numerical rating scale pain score, or intravenous morphine requirements from day 1 to day 7. CONCLUSIONS: EA was not associated with a lower risk of IMV in chest trauma patients with at least 3 fractured ribs, moderate pain, and no intubation on admission. Further studies are needed to clarify the optimal pain control strategy in chest trauma patients admitted to the ICU, notably those with severe pain or high opioid requirements.

Benefit-to-risk balance of bronchoalveolar lavage in the critically ill. A prospective, multicenter cohort study.

PURPOSE: To assess the benefit-to-risk balance of bronchoalveolar lavage (BAL) in intensive care unit (ICU) patients. METHODS: In 16 ICUs, we prospectively collected adverse events during or within 24 h after BAL and assessed the BAL input for decision making in consecutive adult patients. The occurrence of a clinical adverse event at least of grade 3, i.e., sufficiently severe to need therapeutic action(s), including modification(s) in respiratory support, defined poor BAL tolerance. The BAL input for decision making was declared satisfactory if it allowed to interrupt or initiate one or several treatments. RESULTS: We included 483 BAL in 483 patients [age 63 years (interquartile range (IQR) 53-72); female gender: 162 (33.5%); simplified acute physiology score II: 48 (IQR 37-61); immunosuppression 244 (50.5%)]. BAL was begun in non-intubated patients in 105 (21.7%) cases. Sixty-seven (13.9%) patients reached the grade 3 of adverse event or higher. Logistic regression showed that a BAL performed by a non-experienced physician (non-pulmonologist, or intensivist with less than 10 years in the specialty or less than 50 BAL performed) was the main predictor of poor BAL tolerance in non-intubated patients [OR: 3.57 (95% confidence interval 1.04-12.35); P = 0.04]. A satisfactory BAL input for decision making was observed in 227 (47.0%) cases and was not predictable using logistic regression. CONCLUSIONS: Adverse events related to BAL in ICU patients are not infrequent nor necessarily benign. Our findings call for an extreme caution, when envisaging a BAL in ICU patients and for a mandatory accompaniment of the less experienced physicians.
