Purpose
Premorbid conditions affect prognosis of acutely-ill aged patients. Several lines of evidence suggest geriatric syndromes need to be assessed but little is known on their relative effect on ...the 30-day survival after ICU admission. The primary aim of this study was to describe the prevalence of frailty, cognition decline and activity of daily life in addition to the presence of comorbidity and polypharmacy and to assess their influence on 30-day survival.
Methods
Prospective cohort study with 242 ICUs from 22 countries. Patients 80 years or above acutely admitted over a six months period to an ICU between May 2018 and May 2019 were included. In addition to common patients’ characteristics and disease severity, we collected information on specific geriatric syndromes as potential predictive factors for 30-day survival, frailty (Clinical Frailty scale) with a CFS > 4 defining frail patients, cognitive impairment (informant questionnaire on cognitive decline in the elderly (IQCODE) with IQCODE ≥ 3.5 defining cognitive decline, and disability (measured the activity of daily life with the Katz index) with ADL ≤ 4 defining disability. A Principal Component Analysis to identify co-linearity between geriatric syndromes was performed and from this a multivariable model was built with all geriatric information or only one: CFS, IQCODE or ADL. Akaike’s information criterion across imputations was used to evaluate the goodness of fit of our models.
Results
We included 3920 patients with a median age of 84 years (IQR: 81–87), 53.3% males). 80% received at least one organ support. The median ICU length of stay was 3.88 days (IQR: 1.83–8). The ICU and 30-day survival were 72.5% and 61.2% respectively. The geriatric conditions were median (IQR): CFS: 4 (3–6); IQCODE: 3.19 (3–3.69); ADL: 6 (4–6); Comorbidity and Polypharmacy score (CPS): 10 (7–14). CFS, ADL and IQCODE were closely correlated. The multivariable analysis identified predictors of 1-month mortality (HR; 95% CI): Age (per 1 year increase): 1.02 (1.–1.03,
p
= 0.01), ICU admission diagnosis, sequential organ failure assessment score (SOFA) (per point): 1.15 (1.14–1.17,
p
< 0.0001) and CFS (per point): 1.1 (1.05–1.15,
p
< 0.001). CFS remained an independent factor after inclusion of life-sustaining treatment limitation in the model.
Conclusion
We confirm that frailty assessment using the CFS is able to predict short-term mortality in elderly patients admitted to ICU. Other geriatric syndromes do not add improvement to the prediction model. Since CFS is easy to measure, it should be routinely collected for all elderly ICU patients in particular in connection to advance care plans, and should be used in decision making.
Intensive care unit (ICU)-acquired weakness often develops in patients who are undergoing invasive mechanical ventilation. Early active mobilization may mitigate ICU-acquired weakness, increase ...survival, and reduce disability.
We randomly assigned 750 adult patients in the ICU who were undergoing invasive mechanical ventilation to receive increased early mobilization (sedation minimization and daily physiotherapy) or usual care (the level of mobilization that was normally provided in each ICU). The primary outcome was the number of days that the patients were alive and out of the hospital at 180 days after randomization.
The median number of days that patients were alive and out of the hospital was 143 (interquartile range, 21 to 161) in the early-mobilization group and 145 days (interquartile range, 51 to 164) in the usual-care group (absolute difference, -2.0 days; 95% confidence interval CI, -10 to 6; P = 0.62). The mean (±SD) daily duration of active mobilization was 20.8±14.6 minutes and 8.8±9.0 minutes in the two groups, respectively (difference, 12.0 minutes per day; 95% CI, 10.4 to 13.6). A total of 77% of the patients in both groups were able to stand by a median interval of 3 days and 5 days, respectively (difference, -2 days; 95% CI, -3.4 to -0.6). By day 180, death had occurred in 22.5% of the patients in the early-mobilization group and in 19.5% of those in the usual-care group (odds ratio, 1.15; 95% CI, 0.81 to 1.65). Among survivors, quality of life, activities of daily living, disability, cognitive function, and psychological function were similar in the two groups. Serious adverse events were reported in 7 patients in the early-mobilization group and in 1 patient in the usual-care group. Adverse events that were potentially due to mobilization (arrhythmias, altered blood pressure, and desaturation) were reported in 34 of 371 patients (9.2%) in the early-mobilization group and in 15 of 370 patients (4.1%) in the usual-care group (P = 0.005).
Among adults undergoing mechanical ventilation in the ICU, an increase in early active mobilization did not result in a significantly greater number of days that patients were alive and out of the hospital than did the usual level of mobilization in the ICU. The intervention was associated with increased adverse events.

Spontaneous-breathing trials can be performed with the use of either pressure-support ventilation (PSV) or a T-piece. Whether PSV trials may result in a shorter time to tracheal extubation than ...T-piece trials, without resulting in a higher risk of reintubation, among patients who have a high risk of extubation failure is unknown.
In this multicenter, open-label trial, we randomly assigned patients who had a high risk of extubation failure (i.e., were >65 years of age or had an underlying chronic cardiac or respiratory disease) to undergo spontaneous-breathing trials performed with the use of either PSV (with a pressure-support level of 8 cm of water and no positive end-expiratory pressure) or a T-piece. The primary outcome was the total time without exposure to invasive ventilation (reported as the number of ventilator-free days) at day 28 after the initial spontaneous-breathing trial. Secondary outcomes included extubation within 24 hours and extubation within 7 days after the initial spontaneous-breathing trial, as well as reintubation within 7 days after extubation.
A total of 969 patients (484 in the PSV group and 485 in the T-piece group) were included in the analysis. At day 28, the median number of ventilator-free days was 27 (interquartile range, 24 to 27) in the PSV group and 27 (interquartile range, 23 to 27) in the T-piece group (difference, 0 days; 95% confidence interval CI, -0.5 to 1; P = 0.31). Extubation was performed within 24 hours in 376 patients (77.7%) in the PSV group and in 350 patients (72.2%) in the T-piece group (difference, 5.5 percentage points; 95% CI, 0.01 to 10.9), and extubation was performed within 7 days in 473 patients (97.7%) and 458 patients (94.4%), respectively (difference, 3.3 percentage points; 95% CI, 0.8 to 5.9). Reintubation was performed in 72 of 481 patients (14.9%) in the PSV group and in 65 of 477 patients (13.6%) in the T-piece group (difference, 1.3 percentage points; 95% CI, -3.1 to 5.8). Cardiac or respiratory arrest was a reason for reintubation in 9 patients (3 in the PSV group and 6 in the T-piece group).
Among patients who had a high risk of extubation failure, spontaneous-breathing trials performed with PSV did not result in significantly more ventilator-free days at day 28 than spontaneous-breathing trials performed with a T-piece.

Purpose
Cardiac arrest may occur unexpectedly in intensive care units (ICU). We hypothesize that certain patient characteristics and treatments are associated with survival and long-term functional ...outcome following in-ICU cardiac arrest.
Methods
Over a 12-month period, cardiac arrests with resuscitation attempts were prospectively investigated in 45 French ICUs. Survivors were followed for 6 months.
Results
In total, 677 (2.16%) of 31,399 admitted patients had at least one in-ICU cardiac arrest with resuscitation attempt, 42% of which occurred on the day of admission. In 79% cases, one or more condition(s) likely to promote the occurrence of cardiac arrest was/were identified, including hypoxia (179 patients), metabolic disorders (122), hypovolemia (94), and adverse events linked to the life-sustaining devices in place (98). Return of spontaneous circulation was achieved in 478 patients, of whom 163 were discharged alive from ICU and 146 from hospital. Six-month survival with no or moderate functional sequel (118 of 125 patients alive) correlated with a number of organ failures ≤ 2 when cardiac arrest occurred (OR 4.17 1.92–9.09), resuscitation time ≤ 5 min (3.32 2.01–5.47), shockable rhythm cardiac arrests (2.13 1.26–3.45) or related to the life-sustaining devices in place (2.11 1.22–3.65), absence of preexisting disability (1.98 1.09–3.60) or disease deemed fatal within 5 years (1.70 1.05–2.77), and sedation (1.71 1.06–2.75).
Conclusion
Only one in six patients with in-ICU cardiac arrest and resuscitation attempt was alive at 6 months with good functional status. Certain characteristics specific to cardiac arrests, resuscitation maneuvers, and the pathological context in which they happen may help clarify prognosis and inform relatives.
In a previous study of subjects suspected of having ventilator-associated pneumonia, a rapid susceptibility testing approach by using ETEST (BioMérieux) strips directly applied to bronchoalveolar ...lavage samples provided valuable information at hour 24. The primary objective of this study was to assess a new direct specimen testing by using an even more-rapid E-test approach (at hour 10), which could promote an early de-escalation of the antimicrobial therapy.
Twenty-eight subjects with ventilator-associated pneumonia admitted to a medical ICU were prospectively included. In parallel with standard routine methods, E-test strips were directly applied onto agar plates seeded with bronchoalveolar lavage samples and were analyzed after 10 h of incubation. E-test results were used to identify potential drug choices by simulating clinical decision making if the microscopy results had been available at the point of care. These choices were analyzed for concordance with the narrowest adequate antimicrobial therapy according to the Minimum Inhibitory Concentrations (MICs) provided by the reference method (ie, the laboratory routine diagnostic).
At hour 10, direct specimen testing was readable in 18 of 28 bronchoalveolar lavage samples (64%). Total agreement between the 10-h direct specimen testing approach and the laboratory routine diagnostic approach was 90%, with a sensitivity of 83% and a specificity of 95%, with 8% major errors and 3% very major errors. The concordance between the 2 tests was very good (kappa = 0.79). If the 10-h E-test results were taken into account, then an early de-escalation strategy would have been possible in 10 of 18 cases (55%) at hour 10.
This rapid susceptibility testing approach provided early (10 h) and valuable information that could lead to an early adjustment of empirical antimicrobial treatment in a ventilator-associated pneumonia setting. (ClinicalTrials.gov registration NCT01266863.).
Ventricular arrhythmia is common after left ventricular assist device (LVAD) implantation, especially in the early postoperative phase (<30 days).
To identify the incidence of and risk factors for ...electrical storm (ES) occurring within 30 days of HeartMate® II implantation.
We reviewed data from all consecutive patients undergoing HeartMate® II device implantation at our institution from January 2008 to December 2014. Patient demographic data, pharmacotherapies and outcomes were collected. The primary endpoint was occurrence of early ES (within 30 days of surgery), defined as three or more separate episodes of sustained ventricular arrhythmia within a 24-hour interval, requiring appropriate therapy.
Forty-three patients (mean age 56.7±11.2 years; 39 men) were included. At HeartMate® II implantation, mean left ventricular ejection fraction was 20±5%, 32 (74.4%) patients had ischaemic cardiomyopathy and 31 (72.1%) were implanted with an indication of bridge to cardiac transplantation. During follow-up, 12 (27.9%) patients experienced early ES after HeartMate® II implantation (median delay 9.1±7.8 days). Early ES was more frequent in larger patients (body surface area 1.99 vs 1.81 m2; P<0.01), tended to be associated with previous sustained ventricular tachycardia (50.0% vs 22.6%; P=0.08), previous implantable cardioverter-defibrillator implantation (66.7% vs 38.7%; P=0.09), discontinuation of long-term beta-blocker therapy (75.0% vs 45.2%; P=0.08), weaning of adrenergic drugs after the third day (66.7% vs 35.5%; P=0.06) and the use of extracorporeal life support (50% vs 22.6%; P=0.079), but was not associated with the cardiomyopathy aetiology or the indication for assistance. Catheter ventricular tachycardia ablation was performed in six (14.0%) patients. Early ES was associated with a significantly higher all-cause mortality rate at the 30th day (33.3% vs 6.5%; P=0.02).
ES is a common and pejorative feature in the early postoperative period.
L’arythmie ventriculaire (AV) est fréquente après l’implantation d’une assistance ventriculaire gauche (AVG), particulièrement dans la phase postopératoire précoce (30 premiers jours). Nous avons cherché à identifier l’incidence et les facteurs de risque des orages rythmiques (OR) survenant précocement après implantation d’une prothèse HeartMate® II (HM2, Thoratec Corporation, Plesanton, États-Unis).
Nous avons analysé les données de tous les patients implantés d’un HM2 dans notre institution de janvier 2008 jusqu’à décembre 2014. Les données démographiques, pharmacologiques et le devenir ont été recueillis. Le critère principal était la survenue d’un OR précoce (dans les 30jours après la chirurgie) – défini comme la survenue, sur un intervalle de 24heures, d’au moins 3 épisodes distincts d’AV soutenue ayant nécessité une thérapie appropriée.
Quarante-trois patients (39 homes, âge 57±11 ans) ont été inclus. À l’implantation, la FEVG moyenne était de 20±5 %, 32 (74 %) avaient une cardiomyopathie ischémique, 31 (72 %) ont été implantés dans l’attente d’une transplantation cardiaque. Durant le suivi, 12 patients (28 %) ont présenté un OR précoce, avec un délai médian de 9±8jours. Les OR précoces étaient significativement plus fréquents chez les patients avec une large surface corporelle (1,99 vs 1,81 m2, p<0,01) et tendaient à être associés aux patients avec un antécédent de tachycardie ventriculaire (TV) soutenue (50 % vs 22 %, p=0,08), porteurs d’un défibrillateur automatique (66,7 % vs 38,7 %, p=0,09), à l’arrêt d’un traitement prolongé par bêtabloquant (75 % vs 45 %, p=0,08), au sevrage des drogues adrénergiques après le troisième jour (66,7 % vs 35,5 %, p=0,06) et au recours à une assistance cardiaque extracorporelle (50 % vs 22,6 %, p=0,079), tandis qu’ils n’étaient associés ni à l’étiologie de la cardiopathie ni à l’indication de l’assistance. Une ablation de TV a été réalisée chez 6 patients (14 %) sous HM2. Les OR précoces étaient associés à une surmortalité à j30 (33,3 % vs 6,5 %, p=0,02).
Les OR postopératoires précoces sont une complication fréquente grevant le pronostic des patients.
ObjectivesIn Europe, there is a distinction between two different healthcare organisation systems, the tax-based healthcare system (THS) and the social health insurance system (SHI). Our aim was to ...investigate whether the characteristics, treatment and mortality of older, critically ill patients in the intensive care unit (ICU) differed between THS and SHI.SettingICUs in 16 European countries.ParticipantsIn total, 7817 critically ill older (≥80 years) patients were included in this study, 4941 in THS and 2876 in the SHI systems.Primary and secondary outcomes measuresWe chose generalised estimation equations with robust standard errors to produce population average adjusted OR (aOR). We adjusted for patient-specific variables, health economic data, including gross domestic product (GDP) and human development index (HDI), and treatment strategies.ResultsIn SHI systems, there were higher rates of frail patients (Clinical Frailty Scale>4; 46% vs 41%; p<0.001), longer length of ICU stays (90±162 vs 72±134 hours; p<0.001) and increased levels of organ support. The ICU mortality (aOR 1.50, 95% CI 1.09 to 2.06; p=0.01) was consistently higher in the SHI; however, the 30-day mortality (aOR 0.89, 95% CI 0.66 to 1.21; p=0.47) was similar between THS and SHI. In a sensitivity analysis stratifying for the health economic data, the 30-day mortality was higher in SHI, in low GDP per capita (aOR 2.17, 95% CI 1.42 to 3.58) and low HDI (aOR 1.22, 95% CI 1.64 to 2.20) settings.ConclusionsThe 30-day mortality was similar in both systems. Patients in SHI were older, sicker and frailer at baseline, which could be interpreted as a sign for a more liberal admission policy in SHI. We believe that the observed trend towards ICU excess mortality in SHI results mainly from a more liberal admission policy and an increase in treatment limitations.Trial registration numbers NCT03134807 and NCT03370692.
