Favorable outcome without corticosteroids during post-artesunate delayed hemolysis with positive direct antiglobulin test in severe imported Plasmodium falciparum malaria, France.

OBJECTIVES: Positive direct antiglobulin tests (DATs) have been reported in cases of post-artesunate delayed hemolysis (PADH), but the causal role of auto-immune hemolysis remains unclear. We aimed to analyze a cohort of patients with PADH and DAT during severe malaria. METHODS: We describe PADH and DAT results in a 7-year multi-center retrospective cohort of patients receiving artesunate for severe imported malaria. RESULTS: Of 337 patients treated with artesunate, 46 (13.6%) had at least one DAT result within 30 days of treatment initiation, and 25/46 (54.3%) had at least one positive DAT. Among 40 patients with available data, 17 (42.5%) experienced PADH. Patient characteristics were similar for patients with a positive or negative DAT, and DAT positivity was not associated with PADH occurrence (P = 0.36). Among patients, 5/13 (38.5%) with a positive DAT after day 7 experienced PADH, compared to 10/13 (76.9%) of those with a negative DAT after day 7 (P = 0.11). Overall, 41% of patients required blood transfusions, and outcome was favorable without corticosteroids, even in cases of PADH. CONCLUSIONS: DAT does not appear to be a marker of PADH, but rather an indirect marker of an immune-mediated mechanism. DAT positivity should not lead to the administration of systemic corticosteroids during PADH.

Prospective evaluation of the efficacy, safety, and optimal biomarker enrichment strategy for nangibotide, a TREM-1 inhibitor, in patients with septic shock (ASTONISH): a double-blind, randomised, controlled, phase 2b trial.

BACKGROUND: Activation of the triggering receptor expressed on myeloid cells-1 (TREM-1) pathway is associated with septic shock outcomes. Data suggest that modulation of this pathway in patients with activated TREM-1 might improve survival. Soluble TREM-1 (sTREM-1), a potential mechanism-based biomarker, might facilitate enrichment of patient selection in clinical trials of nangibotide, a TREM-1 modulator. In this phase 2b trial, we aimed to confirm the hypothesis that TREM1 inhibition might improve outcomes in patients with septic shock. METHODS: This double-blind, randomised, placebo-controlled, phase 2b trial assessed the efficacy and safety of two different doses of nangibotide compared with placebo, and aimed to identify the optimum treatment population, in patients across 42 hospitals with medical, surgical, or mixed intensive care units (ICUs) in seven countries. Non-COVID-19 patients (18-85 years) meeting the standard definition of septic shock, with documented or suspected infection (lung, abdominal, or urinary [in patients ≥65 years]), were eligible within 24 h of vasopressor initiation for the treatment of septic shock. Patients were randomly assigned in a 1:1:1 ratio to intravenous nangibotide 0·3 mg/kg per h (low-dose group), nangibotide 1·0 mg/kg per h (high-dose group), or matched placebo, using a computer-generated block randomisation scheme (block size 3). Patients and investigators were masked to treatment allocation. Patients were grouped according to sTREM-1 concentrations at baseline (established from sepsis observational studies and from phase 2a change to data) into high sTREM-1 (≥ 400 pg/mL). The primary outcome was the mean difference in total Sequential Organ Failure Assessment (SOFA) score from baseline to day 5 in the low-dose and high-dose groups compared with placebo, measured in the predefined high sTREM-1 (≥ 400 pg/mL) population and in the overall modified intention-to-treat population. Secondary endpoints included all-cause 28-day mortality, safety, pharmacokinetics, and evaluation of the relationship between TREM-1 activation and treatment response. This study is registered with EudraCT, 2018-004827-36, and Clinicaltrials.gov, NCT04055909. FINDINGS: Between Nov 14, 2019, and April 11, 2022, of 402 patients screened, 355 were included in the main analysis (116 in the placebo group, 118 in the low-dose group, and 121 in the high-dose group). In the preliminary high sTREM-1 population (total 253 [71%] of 355; placebo 75 [65%] of 116; low-dose 90 [76%] of 118; high-dose 88 [73%] of 121), the mean difference in SOFA score from baseline to day 5 was 0·21 (95% CI -1·45 to 1·87, p=0·80) in the low-dose group and 1·39 (-0·28 to 3·06, p=0·104) in the high-dose group versus placebo. In the overall population, the difference in SOFA score from baseline to day 5 between the placebo group and low-dose group was 0·20 (-1·09 to 1·50; p=0·76),and between the placebo group and the high-dose group was 1·06 (-0·23 to 2·35, p=0·108). In the predefined high sTREM-1 cutoff population, 23 (31%) patients in the placebo group, 35 (39%) in the low-dose group, and 25 (28%) in the high-dose group had died by day 28. In the overall population, 29 (25%) patients in the placebo, 38 (32%) in the low-dose, and 30 (25%) in the high-dose group had died by day 28. The number of treatment-emergent adverse events (111 [96%] patients in the placebo group, 113 [96%] in the low-dose group, and 115 [95%] in the high-dose group) and serious treatment-emergent adverse events (28 [24%], 26 [22%], and 31 [26%]) was similar between all three groups. High-dose nangibotide led to a clinically relevant improvement in SOFA score (of two points or more) from baseline to day 5 over placebo in those with higher cutoff concentrations (≥532 pg/mL) of sTREM-1 at baseline. Low dose nangibotide displayed a similar pattern with lower magnitude of effect across all cutoff values. INTERPRETATION: This trial did not achieve the primary outcome of improvement in SOFA score at the predefined sTREM-1 value. Future studies are needed to confirm the benefit of nangibotide at higher concentrations of TREM-1 activation. FUNDING: Inotrem.

Serologic characteristics of oxaliplatin antibodies in 15 patients with drug-induced immune hemolytic anemia.

BACKGROUND: Oxaliplatin, a third-generation platinum derivative is commonly used in combination treatment of metastatic colorectal cancer. Since 2008, it is the second most common cause of drug-induced immune hemolytic anemia (DIIHA) investigated in our laboratory. STUDY DESIGN AND METHODS: Samples from fifteen patients including nine (60%) with intravascular hemolysis, suspected of having DIIHA were studied for the presence of anti-oxaliplatin. Direct antiglobulin tests (DATs) and tests with oxaliplatin-treated red blood cells (RBCs) or untreated and enzyme-treated RBCs in the presence of oxaliplatin were performed. A pool of normal AB sera with no unexpected antibodies was used as a control for nonimmunologic protein adsorption (NIPA). RESULTS: Eleven (73%) of the fifteen patients had antibodies to oxaliplatin that reacted with drug-treated RBCs and untreated RBCs in the presence of drug by tube and/or gel method. Lower-titer reactivity (<20) obtained with four patients' sera and the corresponding pooled normal sera was most likely due to NIPA. Eighty seven percent (13/15) of the patients had positive DAT either with anti-IgG only (33%), IgG + C3d (40%), or C3d only (13%). Two patients had a negative DAT. No directly agglutinating antibody was observed with the pools of normal donor's sera in the presence of oxaliplatin. CONCLUSION: Anti-oxaliplatin can cause severe intravascular hemolysis. Complement can usually be detected on the patient's RBCs and anti-oxaliplatin can be detected in the patient's serum. RBC-bound albumin detection with anti-human albumin needs to be performed to confirm NIPA which could have contributed to the patient's hemolytic anemia.

Assessing physicians' and nurses' experience of dying and death in the ICU: development of the CAESAR-P and the CAESAR-N instruments.

BACKGROUND: As an increasing number of deaths occur in the intensive care unit (ICU), studies have sought to describe, understand, and improve end-of-life care in this setting. Most of these studies are centered on the patient's and/or the relatives' experience. Our study aimed to develop an instrument designed to assess the experience of physicians and nurses of patients who died in the ICU, using a mixed methodology and validated in a prospective multicenter study. METHODS: Physicians and nurses of patients who died in 41 ICUs completed the job strain and the CAESAR questionnaire within 24 h after the death. The psychometric validation was conducted using two datasets: a learning and a reliability cohort. RESULTS: Among the 475 patients included in the main cohort, 398 nurse and 417 physician scores were analyzed. The global score was high for both nurses [62/75 (59; 66)] and physicians [64/75 (61; 68)]. Factors associated with higher CAESAR-Nurse scores were absence of conflict with physicians, pain control handled with physicians, death disclosed to the family at the bedside, and invasive care not performed. As assessed by the job strain instrument, low decision control was associated with lower CAESAR score (61 (58; 65) versus 63 (60; 67), p = 0.002). Factors associated with higher CAESAR-Physician scores were room dedicated to family information, information delivered together by nurse and physician, families systematically informed of the EOL decision, involvement of the nurse during implementation of the EOL decision, and open visitation. They were also higher when a decision to withdraw or withhold treatment was made, no cardiopulmonary resuscitation was performed, and the death was disclosed to the family at the bedside. CONCLUSION: We described and validated a new instrument for assessing the experience of physicians and nurses involved in EOL in the ICU. This study shows important areas for improving practices.

Oxygenation Strategy During Acute Respiratory Failure in Critically-Ill Immunocompromised Patients.

OBJECTIVES: To assess the response to initial oxygenation strategy according to clinical variables available at admission. DESIGN: Multicenter cohort study. SETTING: Thirty French and Belgium medical ICU. SUBJECTS: Immunocompromised patients with hypoxemic acute respiratory failure. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data were extracted from the Groupe de Recherche en Reanimation Respiratoire du patient d'Onco-Hématologie database. Need for invasive mechanical ventilation was the primary endpoint. Secondary endpoint was day-28 mortality. Six-hundred forty-nine patients were included. First oxygenation strategies included standard oxygen (n = 245, 38%), noninvasive ventilation (n = 285; 44%), high-flow nasal cannula oxygen (n = 55; 8%), and noninvasive ventilation + high-flow nasal cannula oxygen (n = 64; 10%). Bilateral alveolar pattern (odds ratio = 1.67 [1.03-2.69]; p = 0.04), bacterial (odds ratio = 1.98 [1.07-3.65]; p = 0.03) or opportunistic infection (odds ratio = 4.75 [2.23-10.1]; p < 0.001), noninvasive ventilation use (odds ratio = 2.85 [1.73-4.70]; p < 0.001), Sequential Organ Failure Assessment score (odds ratio = 1.19 [1.10-1.28]; p < 0.001), and ratio of PaO2 and FIO2 less than 100 at ICU admission (odds ratio = 1.96 [1.27-3.02]; p = 0.0002) were independently associated with intubation rate. Day-28 mortality was independently associated with bacterial (odds ratio = 2.34 [1.10-4.97]; p = 0.03) or opportunistic infection (odds ratio = 4.96 [2.11-11.6]; p < 0.001), noninvasive ventilation use (odds ratio = 2.35 [1.35-4.09]; p = 0.003), Sequential Organ Failure Assessment score (odds ratio = 1.19 [1.10-1.28]; p < 0.001), and ratio of PaO2 and FIO2 less than 100 at ICU admission (odds ratio = 1.97 [1.26-3.09]; p = 0.003). High-flow nasal cannula oxygen use was neither associated with intubation nor mortality rates. CONCLUSIONS: Some clinical characteristics at ICU admission including etiology and severity of acute respiratory failure enable to identify patients at high risk for intubation.

Drug-induced immune hemolytic anemia investigation: Comparison between tube test and microcolumn agglutination (gel test) for the detection of drug-dependent antibodies in the presence of soluble drug.

OBJECTIVES: Testing for drug-dependent antibodies is traditionally performed with the tube method either with drug-treated red blood cells or with untreated red blood cells in the presence of soluble drug. Gel microcolumn agglutination method was compared to tube testing for the demonstration of drug-dependent antibodies in the presence of soluble drug. MATERIALS AND METHODS: Patient's samples were tested in parallel by tube and gel microcolumn agglutination method with untreated and/or enzyme-treated red blood cells in the presence of soluble drug. RESULTS: Twenty six different patient's samples were studied and thirty nine tests performed to investigate antibodies directed against fifteen different drugs. There was a good correlation between the results obtained by tube and gel method in terms of analytical sensitivity and specificity. Reactions appeared to be stronger with the gel test than seen with the conventional tube method for most of the drug antibodies investigated. Enzyme-treated cells should be used in addition to untreated cells to improve the sensitivity of the method for detecting drug-dependent antibodies especially those directed against drugs that do not bind firmly to red blood cells. CONCLUSIONS: Gel method appeared to be sensitive, reliable, reproducible, and comparable to the conventional tube method for the detection of all the drug-dependent antibodies investigated in this study. Further studies need to be performed to evaluate gel testing for the detection of drug-dependent antibodies that only react with drug-treated red blood cells.

Sedation practice and discomfort during withdrawal of mechanical ventilation in critically ill patients at end-of-life: a post-hoc analysis of a multicenter study.

PURPOSE: Little is known on the incidence of discomfort during the end-of-life of intensive care unit (ICU) patients and the impact of sedation on such discomfort. The aim of this study was to assess the incidence of discomfort events according to levels of sedation. METHODS: Post-hoc analysis of an observational prospective multicenter study comparing immediate extubation vs. terminal weaning for end-of-life in ICU patients. Discomforts including gasps, significant bronchial obstruction or high behavioural pain scale score, were prospectively assessed by nurses from mechanical ventilation withdrawal until death. Level of sedation was assessed using the Richmond Agitation-Sedation Scale (RASS) and deep sedation was considered for a RASS - 5. Psychological disorders in family members were assessed up until 12 months after the death. RESULTS: Among the 450 patients included in the original study, 226 (50%) experienced discomfort after mechanical ventilation withdrawal. Patients with discomfort received lower doses of midazolam and equivalent morphine, and were less likely to have deep sedation than patients without discomfort (59% vs. 79%, p < 0.001). After multivariate logistic regression, extubation (as compared terminal weaning) was the only factor associated with discomfort, whereas deep sedation and administration of vasoactive drugs were two factors independently associated with no discomfort. Long-term evaluation of psychological disorders in family members of dead patients did not differ between those with discomfort and the others. CONCLUSION: Discomfort was frequent during end-of-life of ICU patients and was mainly associated with extubation and less profound sedation.

Nutrition During Targeted Temperature Management After Cardiac Arrest: Observational Study of Neurological Outcomes and Nutrition Tolerance.

BACKGROUND: Whether providing nutrition support is beneficial or deleterious during targeted temperature management (TTM) after cardiac arrest is unclear. We therefore performed a retrospective observational study to determine whether early nutrition was beneficial or deleterious during TTM. METHODS: We retrospectively studied patients admitted to our intensive care unit (ICU) between 2008 and 2014 after successfully resuscitated cardiac arrest. We compared the group given nutrition within 48 hours after ICU admission (E+ group) to the group given nutrition later on or not at all (E- group). RESULTS: Of the 203 included patients, 143 were in the E+ group and 60 in the E- group. The E+ group had a significantly higher proportion of patients with a good 3-month neurological outcome (42.7% vs 16.7%, P < 0.001). The difference remained significant after adjustment on a propensity score (odds ratio, 3.47; 95% confidence interval, 1.48-8.14; P = 0.004). The cumulative energy deficit for an energy goal of 20 kcal/kg/d from admission to day 7 was significantly lower in the E+ group (3304 ± 2863 kcal vs 5017 ± 2655 kcal, P < 0.001). Within the E+ group, the subgroups with nutrition initiation when body temperature was <36°C vs ≥36°C were not significantly different regarding the frequencies of early-onset pneumonia, ventilator-associated pneumonia, vomiting, and prokinetic drug use (all P-values > 0.05). CONCLUSIONS: Early nutrition after cardiac arrest during TTM appears safe and may be associated with better neurological outcomes. These findings warrant a randomized controlled trial to resolve the remaining issues.

Effect of Selepressin vs Placebo on Ventilator- and Vasopressor-Free Days in Patients With Septic Shock: The SEPSIS-ACT Randomized Clinical Trial.

IMPORTANCE: Norepinephrine, the first-line vasopressor for septic shock, is not always effective and has important catecholaminergic adverse effects. Selepressin, a selective vasopressin V1a receptor agonist, is a noncatecholaminergic vasopressor that may mitigate sepsis-induced vasodilatation, vascular leakage, and edema, with fewer adverse effects. OBJECTIVE: To test whether selepressin improves outcome in septic shock. DESIGN, SETTING, AND PARTICIPANTS: An adaptive phase 2b/3 randomized clinical trial comprising 2 parts that included adult patients (n = 868) with septic shock requiring more than 5 µg/min of norepinephrine. Part 1 used a Bayesian algorithm to adjust randomization probabilities to alternative selepressin dosing regimens and to trigger transition to part 2, which would compare the best-performing regimen with placebo. The trial was conducted between July 2015 and August 2017 in 63 hospitals in Belgium, Denmark, France, the Netherlands, and the United States, and follow-up was completed by May 2018. INTERVENTIONS: Random assignment to 1 of 3 dosing regimens of selepressin (starting infusion rates of 1.7, 2.5, and 3.5 ng/kg/min; n = 585) or to placebo (n = 283), all administered as continuous infusions titrated according to hemodynamic parameters. MAIN OUTCOMES AND MEASURES: Primary end point was ventilator- and vasopressor-free days within 30 days (deaths assigned zero days) of commencing study drug. Key secondary end points were 90-day mortality, kidney replacement therapy-free days, and ICU-free days. RESULTS: Among 868 randomized patients, 828 received study drug (mean age, 66.3 years; 341 [41.2%] women) and comprised the primary analysis cohort, of whom 562 received 1 of 3 selepressin regimens, 266 received placebo, and 817 (98.7%) completed the trial. The trial was stopped for futility at the end of part 1. Median study drug duration was 37.8 hours (IQR, 17.8-72.4). There were no significant differences in the primary end point (ventilator- and vasopressor-free days: 15.0 vs 14.5 in the selepressin and placebo groups; difference, 0.6 [95% CI, -1.3 to 2.4]; P = .30) or key secondary end points (90-day mortality, 40.6% vs 39.4%; difference, 1.1% [95% CI, -6.5% to 8.8%]; P = .77; kidney replacement therapy-free days: 18.5 vs 18.2; difference, 0.3 [95% CI, -2.1 to 2.6]; P = .85; ICU-free days: 12.6 vs 12.2; difference, 0.5 [95% CI, -1.2 to 2.2]; P = .41). Adverse event rates included cardiac arrhythmias (27.9% vs 25.2% of patients), cardiac ischemia (6.6% vs 5.6%), mesenteric ischemia (3.2% vs 2.6%), and peripheral ischemia (2.3% vs 2.3%). CONCLUSIONS AND RELEVANCE: Among patients with septic shock receiving norepinephrine, administration of selepressin, compared with placebo, did not result in improvement in vasopressor- and ventilator-free days within 30 days. Further research would be needed to evaluate the potential role of selepressin for other patient-centered outcomes in septic shock. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02508649.

"You helped me keep my head above water"-experience of bereavement research after loss of a loved one in the ICU: insights from the ARREVE study.

PURPOSE: Bereavement research has helped to improve end-of-life practices in the ICU. However, few studies have explored bereaved relatives experience of research participation in this context. We aimed to explore the experience of bereaved relatives' participation in the ARREVE study which included three telephone follow-up calls to complete several quantitative tools. METHODS: Volunteer relatives who participated in the 12-month follow-up call completed a questionnaire about research participation that included ten open-ended questions so that respondents could use their own words and thoughts. These open-ended questions were analyzed using qualitative analysis that examines themes within the data. RESULTS: 175/311 relatives completed the questionnaire. Three themes were derived from the thematic analysis: (1) struggling: reactivation of emotional distress associated with the ICU experience and the loss is frequent, specifically during the 1st follow-up call. (2) Resilience: as time goes by, research participation becomes increasingly positive. The calls are a help both in giving meaning to the relatives' experience and in accepting the loss. (3) Recognition: research calls can compensate for the absence of support during bereavement. CONCLUSION: Although some emotional difficulties must be acknowledged, bereavement research is overall associated with benefits, by facilitating emotional adjustments, meaning-making and resilience. Lack of support and social isolation during bereavement are frequent experiences, revealing that support strategies for bereaved relatives should be developed after the loss of a loved one in the ICU.

Effect of an ICU Diary on Posttraumatic Stress Disorder Symptoms Among Patients Receiving Mechanical Ventilation: A Randomized Clinical Trial.

Importance: Keeping a diary for patients while they are in the intensive care unit (ICU) might reduce their posttraumatic stress disorder (PTSD) symptoms. Objectives: To assess the effect of an ICU diary on the psychological consequences of an ICU hospitalization. Design, Setting, and Participants: Assessor-blinded, multicenter, randomized clinical trial in 35 French ICUs from October 2015 to January 2017, with follow-up until July 2017. Among 2631 approached patients, 709 adult patients (with 1 family member each) who received mechanical ventilation within 48 hours after ICU admission for at least 2 days were eligible, 657 were randomized, and 339 were assessed 3 months after ICU discharge. Interventions: Patients in the intervention group (n = 355) had an ICU diary filled in by clinicians and family members. Patients in the control group (n = 354) had usual ICU care without an ICU diary. Main Outcomes and Measures: The primary outcome was significant PTSD symptoms, defined as an Impact Event Scale-Revised (IES-R) score greater than 22 (range, 0-88; a higher score indicates more severe symptoms), measured in patients 3 months after ICU discharge. Secondary outcomes, also measured at 3 months and compared between groups, included significant PTSD symptoms in family members; significant anxiety and depression symptoms in patients and family members, based on a Hospital Anxiety and Depression Scale score greater than 8 for each subscale (range, 0-42; higher scores indicate more severe symptoms; minimal clinically important difference, 2.5); and patient memories of the ICU stay, reported with the ICU memory tool. Results: Among 657 patients who were randomized (median [interquartile range] age, 62 [51-70] years; 126 women [37.2%]), 339 (51.6%) completed the trial. At 3 months, significant PTSD symptoms were reported by 49 of 164 patients (29.9%) in the intervention group vs 60 of 175 (34.3%) in the control group (risk difference, -4% [95% CI, -15% to 6%]; P = .39). The median (interquartile range) IES-R score was 12 (5-25) in the intervention group vs 13 (6-27) in the control group (difference, -1.47 [95% CI, -1.93 to 4.87]; P = .38). There were no significant differences in any of the 6 prespecified comparative secondary outcomes. Conclusions and Relevance: Among patients who received mechanical ventilation in the ICU, the use of an ICU diary filled in by clinicians and family members did not significantly reduce the number of patients who reported significant PTSD symptoms at 3 months. These findings do not support the use of ICU diaries for preventing PTSD symptoms. Trial Registration: ClinicalTrials.gov Identifier: NCT02519725.

Questions to improve family-staff communication in the ICU: a randomized controlled trial.

PURPOSE: Relatives of intensive care unit (ICU) patients suffer emotional distress that impairs their ability to acquire the information they need from the staff. We sought to evaluate whether providing relatives with a list of important questions was associated with better comprehension on day 5. METHODS: Randomized, parallel-group trial. Relatives of mechanically ventilated patients were included from 14 hospitals belonging to the FAMIREA study group in France. A validated list of 21 questions was handed to the relatives immediately after randomization. The primary endpoint was comprehension on day 5. Secondary endpoints were satisfaction (Critical Care Family Needs Inventory, CCFNI) and symptoms of anxiety and depression (Hospital Anxiety and Depression Scale, HADS). RESULTS: Of 394 randomized relatives, 302 underwent the day-5 assessment of all outcomes. Day-5 family comprehension was adequate in 68 (44.2%) and 75 (50.7%) intervention and control group relatives (P = 0.30), respectively. Over the first five ICU days, median number of family-staff meetings/patient was 6 [3-9], median total meeting time was 72.5 [35-110] min, and relatives asked a median of 20 [8-33] questions including 11 [6-13] from the list, with no between-group difference. Satisfaction and anxiety/depression symptoms were not significantly different between groups. The only variable significantly associated with better day-5 comprehension by multivariable analysis was a higher total number of questions asked before day 5. CONCLUSIONS: Providing relatives with a list of questions did not improve day-5 comprehension, secondary endpoints, or information time. Further research is needed to help families obtain the information they need. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02410538.

Very low prevalence of iron deficiency among young French children: A national cross-sectional hospital-based survey.

Although iron deficiency (ID) is considered the most frequent micronutrient deficiency in industrialized countries and is associated with impaired neurodevelopment when occurring in early years, accurate recent estimations of its prevalence are lacking. Our objective was to estimate ID prevalence and associated sociodemographic markers in young children in France. The Saturn-Inf national cross-sectional hospital-based survey recruited 3,831 French children <6 years old between 2008 and 2009 to assess lead poisoning prevalence and to establish a biobank. This secondary analysis measured serum ferritinemia (SF) in sera kept frozen at -80 °C for children with sufficient serum aliquots and C-reactive protein <10 mg/L. For the 657 participating children (17% of the Saturn-Inf study), the median age was 3.9 years (interquartile range: 2.2-5.1); 52% were boys. The median SF was 44 µg/L (interquartile range: 28-71). ID prevalence was 2.8% (95% confidence interval [1.7, 4.7]) and 3.2% (95% confidence interval [2.0, 5.1]) with an SF threshold of 10 and 12 µg/L, respectively. Low SF was significantly associated (p < .05) with mother being a migrant (32 vs. 45 µg/L for a mother born in France) or unemployed (37 vs. 50 µg/L for a mother employed). In this first national cross-sectional hospital-based study in France, ID prevalence was much lower than that in other French and European studies performed in underprivileged populations but close to the lowest values observed in other population-based studies in Europe.

The ICU-Diary study: prospective, multicenter comparative study of the impact of an ICU diary on the wellbeing of patients and families in French ICUs.

BACKGROUND: Post-intensive care syndrome includes the multiple consequences of an intensive care unit (ICU) stay for patients and families. It has become a new challenge for intensivists. Prevention programs have been disappointing, except for ICU diaries, which report the patient's story in the ICU. However, the effectiveness of ICU diaries for patients and families is still controversial, as the interpretation of the results of previous studies was open to criticism hampering an expanded use of the diary. The primary objective of the study is to evaluate the post-traumatic stress syndrome in patients. The secondary objectives are to evaluate the post-traumatic stress syndrome in families, anxiety and depression symptoms in patients and families, and the recollected memories of patients. Endpoints will be evaluated 3 months after ICU discharge or death. METHODS: A prospective, multicenter, randomized, assessor-blind comparative study of the effect of an ICU diary on patients and families. We will compare two groups: one group with an ICU diary written by staff and family and given to the patient at ICU discharge or to the family in case of death, and a control group without any ICU diary. Each of the 35 participating centers will include 20 patients having at least one family member who will likely visit the patient during their ICU stay. Patients must be ventilated within 48 h after ICU admission and not have any previous chronic neurologic or acute condition responsible for cognitive impairments that would hamper their participation in a phone interview. Three months after ICU discharge or death of the patient, a psychologist will contact the patient and family by phone. Post-traumatic stress syndrome will be evaluated using the Impact of Events Scale-Revised questionnaire, anxiety and depression symptoms using the Hospital Anxiety and Depression Scale questionnaire, both in patients and families, and memory recollection using the ICU Memory Tool Questionnaire in patients. The content of a randomized sample of diaries of each center will be analyzed using a grid. An interview of the patients in the intervention arm will be conducted 6 months after ICU discharge to analyze in depth how they use the diary. DISCUSSION: This study will provide new insights on the impact of ICU diaries on post-traumatic stress disorders in patients and families after an ICU stay.

Terminal weaning or immediate extubation for withdrawing mechanical ventilation in critically ill patients (the ARREVE observational study).

PURPOSE: The relative merits of immediate extubation versus terminal weaning for mechanical ventilation withdrawal are controversial, particularly regarding the experience of patients and relatives. METHODS: This prospective observational multicentre study (ARREVE) was done in 43 French ICUs to compare terminal weaning and immediate extubation, as chosen by the ICU team. Terminal weaning was a gradual decrease in the amount of ventilatory assistance and immediate extubation was extubation without any previous decrease in ventilatory assistance. The primary outcome was posttraumatic stress symptoms (Impact of Event Scale Revised, IES-R) in relatives 3 months after the death. Secondary outcomes were complicated grief, anxiety, and depression symptoms in relatives; comfort of patients during the dying process; and job strain in staff. RESULTS: We enrolled 212 (85.5%) relatives of 248 patients with terminal weaning and 190 relatives (90.5%) of 210 patients with immediate extubation. Immediate extubation was associated with airway obstruction and a higher mean Behavioural Pain Scale score compared to terminal weaning. In relatives, IES-R scores after 3 months were not significantly different between groups (31.9 ± 18.1 versus 30.5 ± 16.2, respectively; adjusted difference, -1.9; 95% confidence interval, -5.9 to 2.1; p = 0.36); neither were there any differences in complicated grief, anxiety, or depression scores. Assistant nurses had lower job strain scores in the immediate extubation group. CONCLUSIONS: Compared to terminal weaning, immediate extubation was not associated with differences in psychological welfare of relatives when each method constituted standard practice in the ICU where it was applied. Patients had more airway obstruction and gasps with immediate extubation. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01818895.

"It Was the Only Thing I Could Hold Onto, But ": Receiving a Letter of Condolence After Loss of a Loved One in the ICU: A Qualitative Study of Bereaved Relatives' Experience.

OBJECTIVES: Family members of patients who die in the ICU often remain with unanswered questions and suffer from lack of closure. A letter of condolence may help bereaved relatives, but little is known about their experience of receiving such a letter. The objective of the study was to understand bereaved family members' experience of receiving a letter of condolence. DESIGN: Qualitative study using interviews with bereaved family members who received a letter of condolence and letters written by these family members to the ICU team. This study was designed to provide insight into the results of a larger randomized, controlled, multicenter study. SETTING: Twenty-two ICUs in France. SUBJECTS: Family members who lost a loved one in the ICU and who received a letter of condolence. MEASUREMENTS AND MAIN RESULTS: Thematic analysis was used and was based on 52 interviews and 26 letters. Six themes emerged: 1) a feeling of support, 2) humanization of the medical system, 3) an opportunity for reflection, 4) an opportunity to describe their loved one, 5) continuity and closure, and 6) doubts and ambivalence. Possible difficulties emerged, notably the re-experience of the trauma, highlighting the absence of further support. CONCLUSIONS: This study describes the benefits of receiving a letter of condolence; mainly, it humanizes the medical institution (feeling of support, confirmation of the role played by the relative, supplemental information). However, this study also shows a common ambivalence about the letter of condolence's benefit. Healthcare workers must strive to adapt bereavement follow-up to each individual situation.

Antibiotic Therapy in Comatose Mechanically Ventilated Patients Following Aspiration: Differentiating Pneumonia From Pneumonitis.

OBJECTIVES: To determine the proportion of patients with documented bacterial aspiration pneumonia among comatose ICU patients with symptoms suggesting either bacterial aspiration pneumonia or non-bacterial aspiration pneumonitis. DESIGN: Prospective observational study. SETTING: University-affiliated 30-bed ICU. PATIENTS: Prospective cohort of 250 patients admitted to the ICU with coma (Glasgow Coma Scale score ≤ 8) and treated with invasive mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the proportion of patients with microbiologically documented bacterial aspiration pneumonia. Patients meeting predefined criteria for aspiration syndrome routinely underwent telescopic plugged catheter sampling during bronchoscopy before starting probabilistic antibiotic treatment. When cultures were negative, the antibiotic treatment was stopped. Of 250 included patients, 98 (39.2%) had aspiration syndrome, including 92 before mechanical ventilation discontinuation. Telescopic plugged catheter in these 92 patients showed bacterial aspiration pneumonia in 43 patients (46.7%). Among the remaining 49 patients, 16 continued to receive antibiotics, usually for infections other than pneumonia; of the 33 patients whose antibiotics were discontinued, only two subsequently showed signs of lung infection. In the six patients with aspiration syndrome after mechanical ventilation, and therefore without telescopic plugged catheter, antibiotic treatment was continued for 7 days. Mechanical ventilation duration, ICU length of stay, and mortality did not differ between the 43 patients with bacterial aspiration pneumonia and the 49 patients with non-bacterial aspiration pneumonitis. The 152 patients without aspiration syndrome did not receive antibiotics. CONCLUSIONS: Among comatose patients receiving mechanical ventilation, those without clinical, laboratory, or radiologic evidence of bacterial aspiration pneumonia did not require antibiotics. In those with suspected bacterial aspiration pneumonia, stopping empirical antibiotic therapy when routine telescopic plugged catheter sampling recovered no microorganisms was nearly always effective. This strategy may be a valid alternative to routine full-course antibiotic therapy. Only half the patients with suspected bacterial aspiration pneumonia had this diagnosis confirmed by telescopic plugged catheter sampling.

Effect of a condolence letter on grief symptoms among relatives of patients who died in the ICU: a randomized clinical trial.

PURPOSE: Family members of patients who die in the intensive care unit (ICU) may experience symptoms of stress, anxiety, depression, posttraumatic stress disorder (PTSD), and/or prolonged grief. We evaluated whether grief symptoms were alleviated if the physician and the nurse in charge at the time of death sent the closest relative a handwritten condolence letter. METHODS: Multicenter randomized trial conducted among 242 relatives of patients who died at 22 ICUs in France between December 2014 and October 2015. Relatives were randomly assigned to receiving (n = 123) or not receiving (n = 119) a condolence letter. The primary endpoint was the Hospital Anxiety and Depression Score (HADS) at 1 month. Secondary endpoints included HADS, complicated grief (ICG), and PTSD-related symptoms (IES-R) at 6 months. Observers were blinded to group allocation. RESULTS: At 1 month, 208 (85.9%) relatives completed the HADS; median score was 16 [IQR, 10-22] with and 14 [8-21.5] without the letter (P = 0.36). Although scores were higher in the intervention group, there were no significant differences regarding the HADS-depression subscale (8 [4-12] vs. 6 [2-12], mean difference 1.1 [-0.5 to 2.6]; P = 0.09) and prevalence of depression symptoms (56.0 vs. 42.4%, RR 0.76 [0.57-1.00]; P = 0.05). At 6 months, 190 (78.5%) relatives were interviewed. The intervention significantly increased the HADS (13 [7-19] vs. 10 [4-17.5], P = 0.04), HADS-depression subscale (6 [2-10] vs. 3 [1-9], P = 0.02), prevalence of depression symptoms (36.6 vs. 24.7%, P = 0.05) and PTSD-related symptoms (52.4 vs. 37.1%, P = 0.03). CONCLUSIONS: In relatives of patients who died in the ICU, a condolence letter failed to alleviate grief symptoms and may have worsened depression and PTSD-related symptoms.

Reappraisal of visiting policies and procedures of patient's family information in 188 French ICUs: a report of the Outcomerea Research Group.

BACKGROUND: The relatives of intensive care unit (ICU) patients must cope with both the severity of illness of their loved one and the unfamiliar and stressful ICU environment. This hardship may lead to post-intensive care syndrome. French guidelines provide recommendations on welcoming and informing families of ICU patients. We questioned whether and how they are applied 5 years after their publication. METHODS: We conducted a large survey among French ICUs to evaluate their visiting policies and how information was provided to patient's family. A questionnaire was built up by intensivists and nurses. French ICUs were solicited, and the questionnaire was sent to all participating ICUs, for being filled in by the unit medical and/or nursing head. Data regarding the hospital and ICU characteristics, the visiting policy and procedures, and the management of family information were collected. RESULTS: Among the 289 French ICUs, 188 (65 %) participated. Most ICUs have a waiting room 118/188 (62.8 %) and a dedicated room for meeting the family 152/188 (80.8 %). Of the 188 ICUs, 45 (23.9 %) were opened on a 24-h-a-day basis. In the remaining ICUs, the time period allowed for visits was 4.75 ± 1.83 h (median 5 h). In ICUs where visiting restrictions were reported, open visiting was allowed for end-of-life situations in 107/143 (74.8 %). Children are allowed to visit a patient in 164/188 (87.2 %) regardless of their age in 97/164 (59.1 %) of ICUs. Families received an information leaflet in 168/188 (89.3 %). Information was provided to families through structured meetings in 149/188 (79.2 %) of ICUs at patient admission with participation of nurses and nursing assistants in 133/188 (70.4 %) and 55/188 (29.2 %), respectively. Information delivered to the family was reported in the patient chart by only 111/188 ICUs (59 %). Participation in care was infrequent. CONCLUSIONS: Although French ICUs do not follow the consensus recommendations, slow progress exists compared to previous reports. Implementation of these recommendations is largely needed to offer better welcome and information improvement. Further studies on that topic would enable evaluating remaining obstacles and increasing caregivers' awareness, both critical for further progresses on that topic.
