RESUMO
BACKGROUND: The effect of a liberal transfusion strategy as compared with a restrictive strategy on outcomes in critically ill patients with traumatic brain injury is unclear. METHODS: We randomly assigned adults with moderate or severe traumatic brain injury and anemia to receive transfusion of red cells according to a liberal strategy (transfusions initiated at a hemoglobin level of ≤10 g per deciliter) or a restrictive strategy (transfusions initiated at ≤7 g per deciliter). The primary outcome was an unfavorable outcome as assessed by the score on the Glasgow Outcome Scale-Extended at 6 months, which we categorized with the use of a sliding dichotomy that was based on the prognosis of each patient at baseline. Secondary outcomes included mortality, functional independence, quality of life, and depression at 6 months. RESULTS: A total of 742 patients underwent randomization, with 371 assigned to each group. The analysis of the primary outcome included 722 patients. The median hemoglobin level in the intensive care unit was 10.8 g per deciliter in the group assigned to the liberal strategy and 8.8 g per deciliter in the group assigned to the restrictive strategy. An unfavorable outcome occurred in 249 of 364 patients (68.4%) in the liberal-strategy group and in 263 of 358 (73.5%) in the restrictive-strategy group (adjusted absolute difference, restrictive strategy vs. liberal strategy, 5.4 percentage points; 95% confidence interval, -2.9 to 13.7). Among survivors, a liberal strategy was associated with higher scores on some but not all the scales assessing functional independence and quality of life. No association was observed between the transfusion strategy and mortality or depression. Venous thromboembolic events occurred in 8.4% of the patients in each group, and acute respiratory distress syndrome occurred in 3.3% and 0.8% of patients in the liberal-strategy and restrictive-strategy groups, respectively. CONCLUSIONS: In critically ill patients with traumatic brain injury and anemia, a liberal transfusion strategy did not reduce the risk of an unfavorable neurologic outcome at 6 months.

BACKGROUND: Despite advances in defibrillation technology, shock-refractory ventricular fibrillation remains common during out-of-hospital cardiac arrest. Double sequential external defibrillation (DSED; rapid sequential shocks from two defibrillators) and vector-change (VC) defibrillation (switching defibrillation pads to an anterior-posterior position) have been proposed as defibrillation strategies to improve outcomes in patients with refractory ventricular fibrillation. METHODS: We conducted a cluster-randomized trial with crossover among six Canadian paramedic services to evaluate DSED and VC defibrillation as compared with standard defibrillation in adult patients with refractory ventricular fibrillation during out-of-hospital cardiac arrest. Patients were treated with one of these three techniques according to the strategy that was randomly assigned to the paramedic service. The primary outcome was survival to hospital discharge. Secondary outcomes included termination of ventricular fibrillation, return of spontaneous circulation, and a good neurologic outcome, defined as a modified Rankin scale score of 2 or lower (indicating no symptoms to slight disability) at hospital discharge. RESULTS: A total of 405 patients were enrolled before the data and safety monitoring board stopped the trial because of the coronavirus disease 2019 pandemic. A total of 136 patients (33.6%) were assigned to receive standard defibrillation, 144 (35.6%) to receive VC defibrillation, and 125 (30.9%) to receive DSED. Survival to hospital discharge was more common in the DSED group than in the standard group (30.4% vs. 13.3%; relative risk, 2.21; 95% confidence interval [CI], 1.33 to 3.67) and more common in the VC group than in the standard group (21.7% vs. 13.3%; relative risk, 1.71; 95% CI, 1.01 to 2.88). DSED but not VC defibrillation was associated with a higher percentage of patients having a good neurologic outcome than standard defibrillation (relative risk, 2.21 [95% CI, 1.26 to 3.88] and 1.48 [95% CI, 0.81 to 2.71], respectively). CONCLUSIONS: Among patients with refractory ventricular fibrillation, survival to hospital discharge occurred more frequently among those who received DSED or VC defibrillation than among those who received standard defibrillation.

PURPOSE: Antipsychotic agents, which may increase the risk of infection through dopaminergic dysregulation, are prescribed to a fraction of patients following critical illness. We compared the rate of recurrent sepsis among patients who filled a prescription for antipsychotics with high- or low-D2 affinity. METHODS: Population-based cohort with active comparator design. We included sepsis survivors older than 65 years with intensive care unit admission and new prescription of antipsychotics in Ontario 2008-2019. The primary outcome were recurrent sepsis episodes within 1 year of follow-up. Patients who filled a prescription within 30 days of hospital discharge for high-D2 affinity antipsychotics (e.g., haloperidol) were compared with patients who filled a prescription within 30 days of hospital discharge for low-D2 affinity antipsychotics (e.g., quetiapine). Multivariable zero-inflated Poisson regression models with robust standard errors adjusting for confounding at baseline were used to estimate incidence rate ratios (IRR) and 95% confidence intervals (CI). RESULTS: Overall, 1879 patients filled a prescription for a high-D2, and 1446 patients filled a prescription for a low-D2 affinity antipsychotic. Patients who filled a prescription for a high-D2 affinity antipsychotic did not present a higher rate of recurrent sepsis during 1 year of follow-up, compared with patients who filled a prescription for a low-D2 affinity antipsychotic (IRR: 1.12; 95% CI: 0.94, 1.35). CONCLUSIONS: We did not find conclusive evidence of a higher rate of recurrent sepsis associated with the prescription of high-D2 affinity antipsychotics (compared with low-D2 affinity antipsychotics) by 1 year of follow-up in adult sepsis survivors with intensive care unit admission.

The clinical trajectory of survivors of critical illness after hospital discharge can be complex and highly unpredictable. Assessing long-term outcomes after critical illness can be challenging because of possible competing events, such as all-cause death during follow-up (which precludes the occurrence of an event of particular interest). In this perspective, we explore challenges and methodological implications of competing events during the assessment of long-term outcomes in survivors of critical illness. In the absence of competing events, researchers evaluating long-term outcomes commonly use the Kaplan-Meier method and the Cox proportional hazards model to analyze time-to-event (survival) data. However, traditional analytical and modeling techniques can yield biased estimates in the presence of competing events. We present different estimands of interest and the use of different analytical approaches, including changes to the outcome of interest, Fine and Gray regression models, cause-specific Cox proportional hazards models, and generalized methods (such as inverse probability weighting). Finally, we provide code and a simulated dataset to exemplify the application of the different analytical strategies in addition to overall reporting recommendations.

OBJECTIVES: To describe risk factors for major cardiovascular events in adults following hospital discharge after sepsis. DESIGN: Population-based cohort study. SETTING: Ontario, Canada (2008-2017). PATIENTS: Adult patients (age 18 yr or older) who survived a first sepsis hospitalization without preexisting cardiovascular disease. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary composite outcome was myocardial infarction, stroke, or cardiovascular death up to 5 years following hospital discharge. We used cause-specific Cox proportional hazards models that accounted for the competing risk of noncardiovascular death to describe factors associated with major cardiovascular events. We identified 268,259 adult patients without cardiovascular disease (median age, 72 yr), of whom 10.4% experienced a major cardiovascular event during a median follow-up of 3 years. After multivariable adjustment, age (hazard ratio [HR], 1.53 for every 10 yr; 95% CI, 1.51-1.54), male sex (HR, 1.23; 95% CI, 1.20-1.26), diabetes mellitus (HR, 1.24; 95% CI, 1.21-1.27), hypertension (HR, 1.34; 95% CI, 1.30-1.38), prevalent atrial fibrillation (HR, 1.46; 95% CI, 1.40-1.52), and chronic kidney disease (HR, 1.11; 95% CI, 1.06-1.16) were associated with major cardiovascular events during long-term follow-up. Sepsis characteristics such as site of infection (pneumonia vs other: HR, 1.09; 95% CI, 1.05-1.12), septic shock (HR, 1.08; 95% CI, 1.05-1.11), and renal replacement therapy (HR, 1.51; 95% CI, 1.38-1.64) were also associated with subsequent cardiovascular events. In an analysis restricting to patients with troponin values measured during the hospitalization (26,400 patients), an elevated troponin was also associated with subsequent cardiovascular events (HR, 1.23; 95% CI, 1.13-1.33). CONCLUSIONS: Classic cardiovascular risk factors, comorbid conditions, and characteristics of the sepsis episode were associated with a higher hazard of major cardiovascular events in adult sepsis survivors. These findings may inform enrichment strategies for future studies.

OBJECTIVE: To evaluate the impact of direct discharge home (DDH) from ICUs compared with ward transfer on safety outcomes of readmissions, emergency department (ED) visits, and mortality. DATA SOURCES: We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Cumulative Index to Nursing and Allied Health Literature from inception until March 28, 2022. STUDY SELECTION: Randomized and nonrandomized studies of DDH patients compared with ward transfer were eligible. DATA EXTRACTION: We screened and extracted studies independently and in duplicate. We assessed risk of bias using the Newcastle-Ottawa Scale for observational studies. A random-effects meta-analysis model and heterogeneity assessment was performed using pooled data (inverse variance) for propensity-matched and unadjusted cohorts. We assessed the overall certainty of evidence for each outcome using the Grading Recommendations Assessment, Development and Evaluation approach. DATA SYNTHESIS: Of 10,228 citations identified, we included six studies. Of these, three high-quality studies, which enrolled 49,376 patients in propensity-matched cohorts, could be pooled using meta-analysis. For DDH from ICU, compared with ward transfers, there was no difference in the risk of ED visits at 30-day (22.4% vs 22.7%; relative risk [RR], 0.99; 95% CI, 0.95-1.02; p = 0.39; low certainty); hospital readmissions at 30-day (9.8% vs 9.6%; RR, 1.02; 95% CI, 0.91-1.15; p = 0.71; very low-to-low certainty); or 90-day mortality (2.8% vs 2.6%; RR, 1.06; 95% CI, 0.95-1.18; p = 0.29; very low-to-low certainty). There were no important differences in the unmatched cohorts or across subgroup analyses. CONCLUSIONS: Very low-to-low certainty evidence from observational studies suggests that DDH from ICU may have no difference in safety outcomes compared with ward transfer of selected ICU patients. In the future, this research question could be further examined by randomized control trials to provide higher certainty data.

BACKGROUND: Sepsis survivors are at elevated risk for cardiovascular disease during long-term follow-up. Whether diabetes influences cardiovascular risk after sepsis survival remains unknown. We sought to describe the association of diabetes with long-term cardiovascular outcomes in adult sepsis survivors. METHODS: Population-based cohort study in the province of Ontario, Canada (2008-2017). Adult survivors of a first sepsis-associated hospitalization, without pre-existing cardiovascular disease, were included. Main exposure was pre-existing diabetes (any type). The primary outcome was the composite of myocardial infarction, stroke, and cardiovascular death. Patients were followed up to 5 years from discharge date until outcome occurrence or end of study period (March 2018). We used propensity score matching (i.e., 1:1 to patients with sepsis but no pre-existing diabetes) to adjust for measured confounding at baseline. Cause-specific Cox proportional hazards models with robust standard errors were used to estimate hazard ratios (HR) alongside 95% confidence intervals (CI). A main secondary analysis evaluated the modification of the association between sepsis and cardiovascular disease by pre-existing diabetes. RESULTS: 78,638 patients with pre-existing diabetes who had a sepsis-associated hospitalization were matched to patients hospitalized for sepsis but without diabetes. Mean age of patients was 71 years, and 55% were female. Median duration from diabetes diagnosis was 9.8 years; mean HbA1c was 7.1%. Adult sepsis survivors with pre-existing diabetes experienced a higher hazard of major cardiovascular disease (HR 1.25; 95% CI 1.22-1.29)-including myocardial infarction (HR 1.40; 95% CI 1.34-1.47) and stroke (HR 1.24; 95% CI 1.18-1.29)-during long-term follow-up compared to sepsis survivors without diabetes. Pre-existing diabetes modified the association between sepsis and cardiovascular disease (risk difference: 2.3%; 95% CI 2.0-2.6 and risk difference: 1.8%; 95% CI 1.6-2.0 for the effect of sepsis-compared to no sepsis-among patients with and without diabetes, respectively). CONCLUSIONS: Sepsis survivors with pre-existing diabetes experience a higher long-term hazard of major cardiovascular events when compared to sepsis survivors without diabetes. Compared to patients without sepsis, the absolute risk increase of cardiovascular events after sepsis is higher in patients with diabetes (i.e., diabetes intensified the higher cardiovascular risk induced by sepsis).

BACKGROUND: Studies examining gender-based differences in outcomes of patients experiencing out-of-hospital cardiac arrest have demonstrated that, despite a higher likelihood of return of spontaneous circulation, women do not have higher survival. METHODS: Patients successfully resuscitated from out-of-hospital cardiac arrest enrolled in the CCC trial (Trial of Continuous or Interrupted Chest Compressions during CPR) were included. Hierarchical multivariable logistic regression models were constructed to evaluate the association between gender and survival after adjustment for age, gender, cardiac arrest rhythm, witnessed status, bystander cardiopulmonary resuscitation, episode location, epinephrine dose, emergency medical services response time, and duration of resuscitation. Do not resuscitate (DNR) and withdrawal of life-sustaining therapy (WLST) order status were used to assess whether differences in postresuscitation outcomes were modified by baseline prognosis. The analysis was replicated among ALPS trial (Amiodarone, Lidocaine, or Placebo in Out-of-Hospital Cardiac Arrest) participants. RESULTS: Among 4875 successfully resuscitated patients, 1825 (37.4%) were women and 3050 (62.6%) were men. Women were older (67.5 versus 65.3 years), received less bystander cardiopulmonary resuscitation (49.1% versus 54.9%), and had a lower proportion of cardiac arrests that were witnessed (55.1% versus 64.5%) or had shockable rhythm (24.3% versus 44.6%, P<0.001 for all). A significantly higher proportion of women received DNR orders (35.7% versus 32.1%, P=0.009) and had WLST (32.8% versus 29.8%, P=0.03). Discharge survival was significantly lower in women (22.5% versus 36.3%, P<0.001; adjusted odds ratio, 0.78 [95% CI, 0.66-0.93]; P=0.005). The association between gender and survival to discharge was modified by DNR and WLST order status such that women had significantly reduced survival to discharge among patients who were not designated DNR (31.3% versus 49.9%, P=0.005; adjusted odds ratio, 0.74 [95% CI, 0.60-0.91]) or did not have WLST (32.3% versus 50.7%, P=0.002; adjusted odds ratio, 0.73 [95% CI, 0.60-0.89]). In contrast, no gender difference in survival was noted among patients receiving a DNR order (6.7% versus 7.4%, P=0.90) or had WLST (2.8% versus 2.4%, P=0.93). Consistent patterns of association between gender and postresuscitation outcomes were observed in the secondary cohort. CONCLUSIONS: Among patients resuscitated after experiencing out-of-hospital cardiac arrest, discharge survival was significantly lower in women than in men, especially among patients considered to have a favorable prognosis.

OBJECTIVES: To compare health service use and clinical outcomes for patients with and without direct discharge to home (DDH) from ICUs in Ontario. DESIGN: Population-based, observational, cohort study using propensity scoring to match patients who were DDH to those not DDH and a preference-based instrumental variable (IV) analysis using ICU-level DDH rate as the IV. SETTING: ICUs in Ontario. PATIENTS: Patients discharged home from a hospitalization either directly or within 48 hours of care in an ICU between April 1, 2015, and March 31, 2017. INTERVENTION: DDH from ICU. MEASUREMENTS AND MAIN RESULTS: Among 76,737 patients in our cohort, 46,859 (61%) were DDH from the ICU. In the propensity matched cohort, the odds for our primary outcome of hospital readmission or emergency department (ED) visit within 30 days were not significantly different for patients DDH (odds ratio [OR], 1.00; 95% CI, 0.96-1.04), and there was no difference in mortality at 90 days for patients DDH (OR, 1.08; 95% CI, 0.97-1.21). The effect on hospital readmission or ED visits was similar in the subgroup of patients discharged from level 2 (OR, 0.98; 95% CI, 0.92-1.04) and level 3 ICUs (OR, 1.02; 95% CI, 0.96-1.09) and in the subgroups with cardiac conditions (OR, 1.03; 95% CI, 0.96-1.12) and noncardiac conditions (OR, 0.98; 95% CI, 0.94-1.03). Similar results were obtained in the IV analysis (coefficient for hospital readmission or ED visit within 30 d = -0.03 ± 0.03 ( se ); p = 0.3). CONCLUSIONS: There was no difference in outcomes for patients DDH compared with ward transfer prior to discharge when two approaches were used to minimize confounding within a large health systemwide observational cohort. We did not evaluate how patients are selected for DDH. Our results suggest that with careful patient selection, this practice might be feasible for routine implementation to ensure efficient and safe use of limited healthcare resources.

BACKGROUND: The probability of undergoing surgery after severe traumatic brain injury (TBI) varies significantly across studies and centers. However, causes of this variability are poorly understood. We hypothesized that intoxication may impact the probability of receiving an urgent neurosurgical procedure among patients with severe TBI. METHODS: We performed a retrospective cohort study of adult patients admitted to a Level I or II trauma center in the United States or Canada with an isolated severe TBI (2012-2016). Data were derived from the Trauma Quality Improvement Program dataset. An urgent neurosurgical procedure was defined as a procedure that occurred within 24 hours of admission. Multivariable logistic regression was utilized to examine the independent effect of intoxication on a patient's likelihood of undergoing an urgent procedure, as well as the timing of the procedure. RESULTS: Of the 33,646 patients with an isolated severe TBI, 11,313 (33.6%) were intoxicated. An urgent neurosurgical procedure was performed in 8,255 (24.5%) cases. Overall, there was no difference in the probability of undergoing an urgent procedure between patients who were and were not intoxicated (OR 0.99; 95% CI 0.94-1.06). While intoxication status had no impact on the probability of surgery among patients with the most severe TBI (head AIS 5: OR 1.06 [95% CI 0.98-1.15]), intoxicated patients on the lower spectrum of injury had lower odds of undergoing an urgent procedure (AIS 3: OR 0.80 [95% CI 0.66-0.97]). Among patients who underwent an urgent procedure, intoxication had no impact on timing. CONCLUSION: Intoxication status was not associated with differences in the probability of undergoing an urgent neurosurgical procedure among all patients with a severe TBI. However, in patients with less severe TBI, intoxication status was associated with decreased likelihood of receiving an urgent intervention. This finding underscores the challenge in the management of intoxicated patients with TBI.

BACKGROUND: There is conflicting evidence on the association between afterhours discharge from the intensive care unit (ICU) and hospital mortality. We examined the effects of afterhours discharge, including the potential effect of residual organ dysfunction, on hospital mortality in a large integrated health region. METHODS: We performed a multi-center retrospective cohort study of 10,463 adults discharged from 9 mixed medical/surgical ICUs in Alberta from June 2012 to December 2014. We applied a 2-stage modeling strategy to investigate the association between afterhours discharge (19:00h to 07:59h) and post-ICU hospital mortality. We applied mixed-effect multi-variable linear regression to assess the relationship between discharge organ dysfunction and afterhours discharge. We then applied mixed-effect multi-variable logistic regression to evaluate the direct, indirect and integrated associations of afterhours discharge on hospital mortality and hospitalization duration. RESULTS: Of 10,463 patients, 23.7% (n = 2,480) were discharged afterhours, of which 27.4% occurred on a holiday or weekend. This varied significantly by ICU size, type, and site. Patients discharged afterhours were more likely medical admissions, had greater multi-morbidity and illness acuity. A greater average SOFA score in the 72 hours prior to ICU discharge was not associated with afterhours discharge. However, a greater average SOFA score was associated with hospital mortality (adjusted-odds ratio [OR], 1.23; 95% CI, 1.18-1.28). Afterhours discharge was associated with higher hospital mortality (adjusted-OR, 1.19; 95% CI, 1.01-1.39), increased hospital stay (adjusted-risk ratio [RR], 1.10; 95% CI, 1.09-1.11) and increased post-ICU stay (adjusted-RR, 1.16; 95% CI, 1.14-1.17) when compared with workhours discharge. CONCLUSIONS: Afterhours discharge is common, occurring in 1 in 4 discharges, and is widely variable across ICUs. Patients discharged afterhours have greater risk of hospital mortality and prolonged hospitalization.

AIM: Patients undergoing colorectal surgery face high rates of emergency room visits and readmission to hospital. These unplanned hospital visits lead to both increased patient anxiety and health care costs. The aim of this study is to evaluate the use of mobile application to support patients undergoing colorectal surgery following discharge from hospital. METHOD: This study is a randomized controlled trial in which the control group will receive standard follow-up care following discharge after surgery and the intervention group will receive standard follow-up care in addition to the mobile application. The primary outcome is the proportion of patients with unplanned hospital visits within 30 days of discharge. The secondary outcomes are patient-reported outcomes on validated scales evaluating their quality of recovery following discharge. A sample size of 670 subjects is planned. For the primary outcome, the control and intervention groups will be compared using a generalized linear model to account for clustering of patients within centres. For the secondary outcomes, the overall scores on the Quality of Recovery 15 and Patient Activation Measure will be analysed using a linear regression model. RESULTS: It is expected that the results of this study will show that the mobile app will lead to significant improvements in unplanned hospital visits as well as improved quality of recovery for patients. CONCLUSION: If the trial is successful, the mobile app can be easily adopted more widely into clinical practice to support patients at home following surgery.

PURPOSE: To evaluate the perceptions and practices of Canadian cardiovascular anesthesiologists and intensivists towards intravenous albumin as a resuscitation fluid in patients undergoing cardiac surgery. METHODS: We conducted a cross-sectional survey of cardiac anesthesiologists and intensivists involved in the care of cardiac surgical patients. The 22-item survey included seven open-ended questions and assessed practice patterns and attitudes towards albumin. Descriptive statistics were analyzed using counts and proportions. Qualitative data were analyzed to identify themes describing albumin use patterns in Canada. RESULTS: A total of 133 respondents from seven provinces participated, with 83 (62%) using albumin perioperatively. The majority of respondents (77%) felt a low fluid balance in cardiac surgical patients was important, and that supplementing crystalloids with albumin was helpful for this objective (67%). There was poor agreement among survey respondents regarding the role of albumin for faster vasopressor weaning or intensive care discharge, and ≥ 90% did not feel albumin reduced mortality, renal injury, or coagulopathy. Nevertheless, cardiac surgical patients were identified as a distinct population where albumin may help to minimize fluid balance. There was an acknowledged paucity of formal evidence supporting possible benefits. Fewer than 10% of respondents could identify institutional or national guidelines for albumin use. A lack of evidence supporting albumin use in cardiac surgical patients, especially those at highest risk of complications, was a frequently identified concern. CONCLUSIONS: The majority of Canadian anesthesiologists and intensivists (62%) use albumin in cardiac surgical patients. There is clinical equipoise regarding its utility, and an acknowledged need for higher quality evidence to guide practice.
RéSUMé: OBJECTIF: Évaluer les perceptions et les pratiques des anesthésiologistes et intensivistes cardiovasculaires canadiens à l'égard de l'albumine intraveineuse comme liquide de réanimation pour les patients bénéficiant d'une chirurgie cardiaque. MéTHODE: Nous avons mené un sondage transversal auprès d'anesthésiologistes et d'intensivistes cardiaques impliqués dans les soins aux patients de chirurgie cardiaque. Le sondage en 22 éléments comprenait sept questions ouvertes et évaluait les habitudes de pratique et les attitudes des praticiens à l'égard de l'albumine. Les statistiques descriptives ont été analysées à l'aide de dénombrements et de proportions. Des données qualitatives ont été analysées pour identifier des thèmes décrivant les tendances d'utilisation de l'albumine au Canada. RéSULTATS: Au total, 133 répondants de sept provinces ont participé, et 83 (62 %) utilisent l'albumine en périopératoire. La majorité des répondants (77 %) estimaient qu'un bilan liquidien négatif était important chez les patients en chirurgie cardiaque et que la supplémentation en cristalloïdes par de l'albumine était utile pour atteindre cet objectif (67 %). Il y avait un faible accord parmi les répondants concernant le rôle de l'albumine pour accélérer le sevrage des vasopresseurs ou la sortie de soins intensifs, et ≥ 90 % ne pensaient pas que l'albumine réduisait la mortalité, les lésions rénales ou la coagulopathie. Néanmoins, les patients en chirurgie cardiaque ont été identifiés comme une population distincte pour laquelle l'albumine pourrait contribuer à minimiser le bilan liquidien. Il y avait un manque reconnu de données probantes formelles à l'appui des avantages possibles. Moins de 10 % des répondants ont pu trouver des lignes directrices institutionnelles ou nationales portant sur l'utilisation de l'albumine. Le manque de données probantes à l'appui de l'utilisation de l'albumine chez les patients en chirurgie cardiaque, en particulier chez ceux présentant le risque le plus élevé de complications, était une préoccupation fréquemment identifiée. CONCLUSION: La majorité des anesthésiologistes et intensivistes canadiens (62 %) utilisent l'albumine chez les patients en chirurgie cardiaque. Il existe un équilibre clinique quant à son utilité et un besoin reconnu de données probantes de meilleure qualité pour guider la pratique.

Importance: Extracorporeal membrane oxygenation (ECMO) is used as temporary cardiorespiratory support in critically ill patients, but little is known regarding long-term psychiatric sequelae among survivors after ECMO. Objective: To investigate the association between ECMO survivorship and postdischarge mental health diagnoses among adult survivors of critical illness. Design, Setting, and Participants: Population-based retrospective cohort study in Ontario, Canada, from April 1, 2010, through March 31, 2020. Adult patients (N=4462; age ≥18 years) admitted to the intensive care unit (ICU), and surviving to hospital discharge were included. Exposures: Receipt of ECMO. Main Outcomes and Measures: The primary outcome was a new mental health diagnosis (a composite of mood disorders, anxiety disorders, posttraumatic stress disorder; schizophrenia, other psychotic disorders; other mental health disorders; and social problems) following discharge. There were 8 secondary outcomes including incidence of substance misuse, deliberate self-harm, death by suicide, and individual components of the composite primary outcome. Patients were compared with ICU survivors not receiving ECMO using overlap propensity score-weighted cause-specific proportional hazard models. Results: Among 642 survivors who received ECMO (mean age, 50.7 years; 40.7% female), median length of follow-up was 730 days; among 3820 matched ICU survivors who did not receive ECMO (mean age, 51.0 years; 40.0% female), median length of follow-up was 1390 days. Incidence of new mental health conditions among survivors who received ECMO was 22.1 per 100-person years (95% confidence interval [CI] 19.5-25.1), and 14.5 per 100-person years (95% CI, 13.8-15.2) among non-ECMO ICU survivors (absolute rate difference of 7.6 per 100-person years [95% CI, 4.7-10.5]). Following propensity weighting, ECMO survivorship was significantly associated with an increased risk of new mental health diagnosis (hazard ratio [HR] 1.24 [95% CI, 1.01-1.52]). There were no significant differences between survivors who received ECMO vs ICU survivors who did not receive ECMO in substance misuse (1.6 [95% CI, 1.1 to 2.4] per 100 person-years vs 1.4 [95% CI, 1.2 to 1.6] per 100 person-years; absolute rate difference, 0.2 per 100 person-years [95% CI, -0.4 to 0.8]; HR, 0.86 [95% CI, 0.48 to 1.53]) or deliberate self-harm (0.4 [95% CI, 0.2 to 0.9] per 100 person-years vs 0.3 [95% CI, 0.2 to 0.3] per 100 person-years; absolute rate difference, 0.1 per 100 person-years [95% CI, -0.2 to 0.4]; HR, 0.68 [95% CI, 0.21 to 2.23]). There were fewer than 5 total cases of death by suicide in the entire cohort. Conclusions and Relevance: Among adult survivors of critical illness, receipt of ECMO, compared with ICU hospitalization without ECMO, was significantly associated with a modestly increased risk of new mental health diagnosis or social problem diagnosis after discharge. Further research is necessary to elucidate the potential mechanisms underlying this relationship.

BACKGROUND AND PURPOSE: Spontaneous intracerebral hemorrhage (ICH) is a devastating form of stroke associated with significant morbidity and mortality. Recent epidemiological data on incidence, mortality, and association with oral anticoagulation are needed. METHODS: Retrospective cohort study of adult patients (≥18 years) with ICH in the entire population of Ontario, Canada (April 1, 2009-March 30, 2019). We captured outcome data using linked health administrative databases. The primary outcome was mortality during hospitalization, as well as at 1 year following ICH. RESULTS: We included 20 738 patients with ICH. Mean (SD) age was 71.3 (15.1) years, and 52.6% of patients were male. Overall incidence of ICH throughout the study period was 19.1/100 000 person-years and did not markedly change over the study period. In-hospital and 1-year mortality were high (32.4% and 45.4%, respectively). Mortality at 2 years was 49.5%. Only 14.5% of patients were discharged home independently. Over the study period, both in-hospital and 1-year mortality reduced by 10.4% (37.5% to 27.1%, P<0.001) and 7.6% (50.0% to 42.4%, P<0.001), respectively. Use of oral anticoagulation was associated with both in-hospital mortality (adjusted odds ratio 1.37 [95% CI, 1.26-1.49]) and 1-year mortality (hazard ratio, 1.18 [95% CI, 1.12-1.25]) following ICH. CONCLUSIONS: Both short- and long-term mortality have decreased in the past decade. Most survivors from ICH are likely to be discharged to long-term care. Oral anticoagulation is associated with both short- and long-term mortality following ICH. These findings highlight the devastating nature of ICH, but also identify significant improvement in outcomes over time.

BACKGROUND: Although greater than 20% of patients hospitalized with heart failure (HF) are admitted to a critical care unit, associated outcomes, and costs have not been delineated. We determined 30-day mortality, 30-day readmissions, and hospital costs associated with direct or delayed critical care unit admission. METHODS: In a population-based analysis, we compared HF patients who were admitted to critical care directly from the emergency department (direct), after initial ward admission (delayed), or never admitted to critical care during their hospital stay (ward-only). RESULTS: Among 178,997 HF patients (median age 80 [IQR 71-86] years, 49.6% men) 36,175 (20.2%) were admitted to critical care during their hospitalization (April 2003 to March 2018). Critical care patients were admitted directly from the emergency department (direct, 81.9%) or after initial ward admission (delayed, 18.1%). Multivariable-adjusted hazard ratios (HR) for all-cause 30-day mortality were: 1.69 for direct (95% confidence interval [CI]; 1.55, 1.84) and 4.92 for delayed (95% CI; 4.26, 5.68) critical care-admitted compared to ward-only patients. Multivariable-adjusted repeated events analysis demonstrated increased risk for all-cause 30-day readmission with both direct (HR 1.04, 95% CI; 1.01, 1.08, Pâ¯= .013) and delayed critical care unit admissions (HR 1.20, 95% CI; 1.13, 1.28, P < .001). Median 30-day costs were $12,163 for direct admissions, $20,173 for delayed admissions, and $9,575 for ward-only patients (P < .001). CONCLUSIONS: While critical care unit admission indicates increased risk of mortality and readmission at 30 days, those who experienced delayed critical care unit admission exhibited the highest risk of death and highest costs of care.

OBJECTIVE: Compared with individual-patient randomized controlled trials, cluster randomized controlled trials have unique methodological and ethical considerations. We evaluated the rationale, methodological quality, and reporting of cluster randomized controlled trials in critical care studies. DATA SOURCES: Systematic searches of Medline, Embase, and Cochrane Central Register were performed. STUDY SELECTION: We included all cluster randomized controlled trials conducted in adult, pediatric, or neonatal critical care units from January 2005 to September 2019. DATA EXTRACTION: Two reviewers independently screened citations, reviewed full texts, protocols, and supplements of potentially eligible studies, abstracted data, and assessed methodology of included studies. DATA SYNTHESIS: From 1,902 citations, 59 cluster randomized controlled trials met criteria. Most focused on quality improvement (24, 41%), antimicrobial therapy (9, 15%), or infection control (9, 15%) interventions. Designs included parallel-group (25, 42%), crossover (21, 36%), and stepped-wedge (13, 22%). Concealment of allocation was reported in 21 studies (36%). Thirteen studies (22%) reported at least one method of blinding. The median total sample size was 1,660 patients (interquartile range, 813-4,295); the median number of clusters was 12 (interquartile range, 5-24); and the median patients per cluster was 141 (interquartile range, 54-452). Sample size calculations were reported in 90% of trials, but only 54% met Consolidated Standards of Reporting Trials guidance for sample size reporting. Twenty-seven of the studies (46%) identified a fixed number of available clusters prior to trial commencement, and only nine (15%) prespecified both the number of clusters and patients required to detect the expected effect size. Overall, 36 trials (68%) achieved the total prespecified sample size. When analyzing data, 44 studies (75%) appropriately adjusted for clustering when analyzing the primary outcome. Only 12 (20%) reported an intracluster coefficient (median 0.047 [interquartile range, 0.01-0.13]). CONCLUSIONS: Cluster randomized controlled trials in critical care typically involve a small and fixed number of relatively large clusters. The reporting of key methodological aspects of these trials is often inadequate.

Rationale: Patients who receive invasive mechanical ventilation (IMV) are usually exposed to opioids as part of their sedation regimen. The rates of posthospital prescribing of opioids are unknown.Objectives: To determine the frequency of persistent posthospital opioid use among patients who received IMV.Methods: We assessed opioid-naive adults who were admitted to an ICU, received IMV, and survived at least 7 days after hospital discharge in Ontario, Canada over a 26-month period (February, 2013 through March, 2015). The primary outcome was new, persistent opioid use during the year after discharge. We assessed factors associated with persistent use by multivariable logistic regression. Patients receiving IMV were also compared with matched hospitalized patients who did not receive intensive care (non-ICU).Measurements and Main Results: Among 25,085 opioid-naive patients on IMV, 5,007 (20.0%; 95% confidence interval [CI], 19.5-20.5) filled a prescription for opioids in the 7 days after hospital discharge. During the next year, 648 (2.6%; 95% CI, 2.4-2.8) of the IMV cohort met criteria for new, persistent opioid use. The patient characteristic most strongly associated with persistent use in the IMV cohort was being a surgical (vs. medical) patient (adjusted odds ratio, 3.29; 95% CI, 2.72-3.97). The rate of persistent use was slightly higher than for matched non-ICU patients (2.6% vs. 1.5%; adjusted odds ratio, 1.37 [95% CI, 1.19-1.58]).Conclusions: A total of 20% of IMV patients received a prescription for opioids after hospital discharge, and 2.6% met criteria for persistent use, an average of 300 new persistent users per year in a population of 14 million. Receipt of surgery was the factor most strongly associated with persistent use.

OBJECTIVE: To describe trends and patient and system factors associated with direct discharge from critical care to home in a large health system. DESIGN: Population-based cohort study of direct discharge to home rates annually over 10 years. We used a multivariable, multilevel random-effects regression model to analyze current factors associated with direct discharge home in a subcohort from the most recent 2 years. SETTING: One hundred seventy-four ICUs in 101 hospitals in Ontario. PATIENTS: All patients discharged from an ICU between April 1, 2007, and March 31, 2017. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Overall, 237,200 patients (21.1%) were discharged directly home from an ICU. The rate of direct discharge to home increased from 18.6% in 2007 to 23.1% in 2017 (annual increase of 1.02; 95% CI, 1.02-1.03). There were marked variations in rates of direct discharge to home across all critical care units. For medical and surgical units, the median odds ratio was 1.76 (95% CI, 1.59-1.92). In these units, direct discharge to home was associated with younger age (odds ratio, 0.36; 95% CI, 0.34-0.39 for age 80-105 vs age 18-39), fewer comorbidities (odds ratio, 1.74; 95% CI, 1.63-1.85 for Charlson comorbidity index of 0 vs 2), diagnoses of overdose/poisoning (odds ratio, 1.35; 95% CI, 1.23-1.47) and diabetic complications (odds ratio, 1.35; 95% CI, 1.2-1.51), and admission after a same-day procedure (odds ratio, 2.82; 95% CI, 2.46-3.23 compared with emergency department). ICU occupancy was inversely associated with direct discharge to home with an odds ratio of 0.88 (95% CI, 0.87-0.88) for each 10% increase. CONCLUSIONS: High rates of direct discharge to home with evidence of significant practice variation combined with identifiable patient characteristics suggest that further evaluation of this increasingly common transition in care is warranted.
