RESUMO
PURPOSE: Insufficient evidence-based recommendations to guide care for patients with devastating brain injuries (DBIs) leave patients vulnerable to inconsistent practice at the emergency department (ED) and intensive care unit (ICU) interface. We sought to characterize the beliefs of Canadian emergency medicine (EM) and critical care medicine (CCM) physician site directors regarding current management practices for patients with DBI. METHODS: We conducted a cross-sectional survey of EM and CCM physician directors of adult EDs and ICUs across Canada (December 2022 to March 2023). Our primary outcome was the proportion of respondents who manage (or consult on) patients with DBI in the ED. We conducted subgroup analyses to compare beliefs of EM and CCM physicians. RESULTS: Of 303 eligible respondents, we received 98 (32%) completed surveys (EM physician directors, 46; CCM physician directors, 52). Most physician directors reported participating in the decision to withdraw life-sustaining measures (WLSM) for patients with DBI in the ED (80%, n = 78), but 63% of these (n = 62) said this was infrequent. Physician directors reported that existing neuroprognostication methods are rarely sufficient to support WLSM in the ED (49%, n = 48) and believed that an ICU stay is required to improve confidence (99%, n = 97). Most (96%, n = 94) felt that providing caregiver visitation time prior to WLSM was a valid reason for ICU admission. CONCLUSION: In our survey of Canadian EM and CCM physician directors, 80% participated in WLSM in the ED for patients with DBI. Despite this, most supported ICU admission to optimize neuroprognostication and patient-centred end-of-life care, including organ donation.
RéSUMé: OBJECTIF: L'insuffisance des recommandations fondées sur des données probantes pour guider les soins aux individus atteints de lésions cérébrales dévastatrices rend ces personnes vulnérables à des pratiques incohérentes à la jonction entre le service des urgences et de l'unité de soins intensifs (USI). Nous avons cherché à caractériser les croyances des directeurs médicaux canadiens en médecine d'urgence et médecine de soins intensifs concernant les pratiques de prise en charge actuelles des personnes ayant subi une lésion cérébrale dévastatrice. MéTHODE: Nous avons réalisé un sondage transversal auprès des directeurs médicaux des urgences et des unités de soins intensifs pour adultes du Canada (décembre 2022 à mars 2023). Notre critère d'évaluation principal était la proportion de répondant·es qui prennent en charge (ou jouent un rôle de consultation auprès) des personnes atteintes de lésions cérébrales dévastatrices à l'urgence. Nous avons effectué des analyses en sous-groupes pour comparer les croyances des médecins des urgences et des soins intensifs. RéSULTATS: Sur les 303 personnes répondantes admissibles, 98 (32 %) ont répondu aux sondages (directions médicales des urgences, 46; directions médicales d'USI, 52). La plupart des directeurs médicaux ont déclaré avoir participé à la décision de retirer des traitements de maintien des fonctions vitales (TFMV) pour des patient·es atteint·es de lésions cérébrales dévastatrices à l'urgence (80 %, n = 78), mais 63 % (n = 62) ont déclaré que c'était peu fréquent. Les directions médicales ont indiqué que les méthodes de neuropronostic existantes sont rarement suffisantes pour appuyer le retrait des TMFV à l'urgence (49 %, n = 48) et croyaient qu'un séjour aux soins intensifs était nécessaire pour améliorer leur confiance en ces méthodes (99 %, n = 97). La plupart (96 %, n = 94) estimaient que le fait d'offrir du temps de visite aux personnes soignantes avant le retrait des TMFV était un motif valable d'admission aux soins intensifs. CONCLUSION: Dans le cadre de notre sondage mené auprès des directions médicales des services d'urgence et des USI au Canada, 80 % d'entre elles ont participé au retrait de TMFV à l'urgence pour des patient·es souffrant de lésions cérébrales dévastatrices. Malgré cela, la plupart d'entre elles étaient en faveur d'une admission aux soins intensifs afin d'optimiser le neuropronostic et les soins de fin de vie axés sur les patient·es, y compris le don d'organes.

BACKGROUND: Immigrants and refugees face unique challenges navigating the health care system to manage severe arthritis, because of unfamiliarity, lack of awareness of surgical options, or access. The purpose of this study was to assess total knee arthroplasty (TKA) uptake, surgical outcomes, and hospital utilization among immigrants and refugees compared with Canadian-born patients. METHODS: We included all adults undergoing primary TKA from January 2011 to December 2020 in Ontario. Cohorts were defined as Canadian-born or immigrants and refugees. We assessed change in yearly TKA utilization for trend. We compared differences in 1-year revision, infection rates, 30-day venous thromboembolism (VTE), presentation to emergency department, and hospital readmission between matched Canadian-born and immigrant and refugee groups. RESULTS: We included 158 031 TKA procedures. A total of 11 973 (7.6%) patients were in the immigrant and refugee group, and 146 058 (92.4%) patients were in the Canadian-born group. The proportion of TKAs in Ontario performed among immigrants and refugees nearly doubled over the 10-year study period (p < 0.001). After matching, immigrants were at relatively lower risk of 1-year revision (0.9% v. 1.6%, p < 0.001), infection (p < 0.001), death (p = 0.004), and surgical complications (p < 0.001). No differences were observed in rates of 30-day VTE or length of hospital stay. Immigrants were more likely to be discharged to rehabilitation (p < 0.001) and less likely to present to the emergency department (p < 0.001) than Canadian-born patients. CONCLUSION: Compared with Canadian-born patients, immigrants and refugees have favourable surgical outcomes and similar rates of resource utilization after TKA. We observed an underutilization of these procedures in Ontario relative to their proportion of the population. This may reflect differences in perceptions of chronic pain or barriers accessing arthroplasty.

PURPOSE: Sociodemographic risks contributing to health inequities are often inadequately captured and reported in critical care studies. To address the lack of standardized terms and definitions, we sought to develop a practical and convenient resource of questions and response options for collecting sociodemographic variables for critical care research. SOURCE: To identify domains and variables that impact health equity, we searched: 1) PubMed for critical care randomized trials (2010 to 2021); 2) high-impact critical care and general medicine journals for special issues relating to equity; and 3) governmental and nongovernmental resources. PRINCIPAL FINDINGS: We identified 23 domains associated with health equity, including pronouns, age, sex, gender identity, sexual orientation, race and ethnicity, visible minorities, language, household income, marital/relationship status, education, disabilities, immigrant and refugee status, employment, primary care access, expanded health insurance, internet access, housing security, food security, dependents, religion, and postal code. For each domain we provided standardized questions and response options; for 13/23 domains, we included more than one version of the question and response categories. CONCLUSION: We developed a standardized, practical, and convenient demographic data collection tool for critical care research studies. Questions and response options can be adapted by researchers for inclusion in individual study questionnaires or case report forms.
RéSUMé: OBJECTIF: Les risques sociodémographiques qui contribuent aux inégalités en matière de santé sont souvent mal saisis et rapportés dans les études de soins intensifs. Pour remédier au manque de termes et de définitions normalisés, nous avons cherché à élaborer une ressource à la fois pratique et utile de questions et d'options de réponse pour le recueil des variables sociodémographiques pour la recherche en soins intensifs. SOURCES: Pour identifier les domaines et les variables qui ont une incidence sur l'équité en santé, nous avons effectué des recherches dans : 1) PubMed, pour en extraire les études randomisées en soins intensifs (2010 à 2021); 2) des revues de soins intensifs et de médecine générale à impact élevé pour identifier les numéros spéciaux liés à l'équité; et 3) les ressources gouvernementales et non gouvernementales. CONSTATATIONS PRINCIPALES: Nous avons identifié 23 domaines associés à l'équité en santé, y compris les pronoms, l'âge, le sexe, l'identité de genre, l'orientation sexuelle, la race et l'origine ethnique, les minorités visibles, la langue, le revenu du ménage, l'état matrimonial / relationnel, l'éducation, les handicaps, le statut d'immigrant·e et de réfugié·e, l'emploi, l'accès aux soins primaires, l'assurance maladie élargie, l'accès à l'internet, la sécurité du logement, la sécurité alimentaire, les personnes à charge, la religion et le code postal. Pour chaque domaine, nous avons fourni des questions et des options de réponse normalisées; pour 13/23 domaines, nous avons inclus plus d'une version des catégories de questions et réponses. CONCLUSION: Nous avons mis au point un outil de collecte de données démographiques normalisé, pratique et utile pour la recherche en soins intensifs. Les options de questions et de réponses peuvent être adaptées par les chercheuses et chercheurs pour être incluses dans des questionnaires d'étude individuels ou des formulaires de présentation de cas.

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.

BACKGROUND: The role of remdesivir in the treatment of patients in hospital with COVID-19 remains ill defined in a global context. The World Health Organization Solidarity randomized controlled trial (RCT) evaluated remdesivir in patients across many countries, with Canada enrolling patients using an expanded data collection format in the Canadian Treatments for COVID-19 (CATCO) trial. We report on the Canadian findings, with additional demographics, characteristics and clinical outcomes, to explore the potential for differential effects across different health care systems. METHODS: We performed an open-label, pragmatic RCT in Canadian hospitals, in conjunction with the Solidarity trial. We randomized patients to 10 days of remdesivir (200 mg intravenously [IV] on day 0, followed by 100 mg IV daily), plus standard care, or standard care alone. The primary outcome was in-hospital mortality. Secondary outcomes included changes in clinical severity, oxygen- and ventilator-free days (at 28 d), incidence of new oxygen or mechanical ventilation use, duration of hospital stay, and adverse event rates. We performed a priori subgroup analyses according to duration of symptoms before enrolment, age, sex and severity of symptoms on presentation. RESULTS: Across 52 Canadian hospitals, we randomized 1282 patients between Aug. 14, 2020, and Apr. 1, 2021, to remdesivir (n = 634) or standard of care (n = 648). Of these, 15 withdrew consent or were still in hospital, for a total sample of 1267 patients. Among patients assigned to receive remdesivir, in-hospital mortality was 18.7%, compared with 22.6% in the standard-of-care arm (relative risk [RR] 0.83 (95% confidence interval [CI] 0.67 to 1.03), and 60-day mortality was 24.8% and 28.2%, respectively (95% CI 0.72 to 1.07). For patients not mechanically ventilated at baseline, the need for mechanical ventilation was 8.0% in those assigned remdesivir, and 15.0% in those receiving standard of care (RR 0.53, 95% CI 0.38 to 0.75). Mean oxygen-free and ventilator-free days at day 28 were 15.9 (± standard deviation [SD] 10.5) and 21.4 (± SD 11.3) in those receiving remdesivir and 14.2 (± SD 11) and 19.5 (± SD 12.3) in those receiving standard of care (p = 0.006 and 0.007, respectively). There was no difference in safety events of new dialysis, change in creatinine, or new hepatic dysfunction between the 2 groups. INTERPRETATION: Remdesivir, when compared with standard of care, has a modest but significant effect on outcomes important to patients and health systems, such as the need for mechanical ventilation. Trial registration: ClinicalTrials.gov, no. NCT04330690.

OBJECTIVES: To evaluate long-term uptake of an antimicrobial stewardship audit-and-feedback program along with potential predictors of stewardship suggestions and acceptance across a diverse ICU population. DESIGN: A retrospective cohort study. SETTING: An urban, academic medical institution. PATIENTS: Patients admitted to an ICU who received an antimicrobial stewardship program suggestion between June 2010 and September 2019. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: The antimicrobial stewardship program provided 7,749 antibiotic assessments over the study period and made a suggestion to alter therapy in 2,826 (36%). Factors associated with a higher likelihood of receiving a suggestion to alter therapy included shorter hospital length of stay prior to antimicrobial stewardship program review (odds ratio 1.15 for ≤ 5 d; 95% CI 1.00-1.32), admission to cardiovascular (1.37; 1.06-1.76) or burn surgery (1.88; 1.50-2.36) versus general medicine, and preceding duration of antibiotic use greater than 5 days (1.33; 1.10-1.60). Assessment of aminoglycosides (2.91; 1.85-4.89), carbapenems (1.93; 1.54-2.41), and vancomycin (2.71; 2.19-3.36) versus ceftriaxone was more likely to result in suggestions to alter therapy. The suggestion acceptance rate was 67% (1,895/2,826), which was stable throughout the study period. Admission to a level 3 ICU was associated with higher likelihood of acceptance of suggestions (1.50; 1.14-1.97). Factors associated with lower acceptance rates were admission to burn surgery (0.64; 0.45-0.91), treatment of pneumonia (0.64; 0.42-0.97 for community-acquired and 0.65; 0.44-0.94 for ventilator-acquired), unknown source of infection (0.66; 0.48-0.92), and suggestion types of "narrow spectrum" (0.65; 0.45-0.94), "change formulation of antibiotic" (0.42; 0.27-0.64), or "change agent of therapy" (0.63; 0.40-0.97) versus "change of dose". CONCLUSIONS: An antimicrobial stewardship program implemented over a decade resulted in sustained suggestion and acceptance rates. These findings support the need for a persistent presence of audit-and-feedback over time with more frequent suggestions to alter potentially nephrotoxic agents, increased efforts toward specialized care units, and further work approaching infectious sources that are typically treated without pathogen confirmation and identification.

BACKGROUND: Studies comparing end-of-life care between patients who are high cost users of the healthcare system compared to those who are not are lacking. AIM: The objective of this study was to describe and measure the association between high cost user status and several health services outcomes for all adults in Canada who died in acute care, compared to non-high cost users and those without prior healthcare use. SETTINGS AND PARTICIPANTS: We used administrative data for all adults who died in hospital in Canada between 2011 and 2015 to measure the odds of admission to the intensive care unit (ICU), receipt of invasive interventions, major surgery, and receipt of palliative care during the hospitalization in which the patient died. High cost users were defined as those in the top 10% of acute healthcare costs in the year prior to a person's hospitalization in which they died. RESULTS: Among 252,648 people who died in hospital, 25,264 were high cost users (10%), 112,506 were non-high cost users (44.5%) and 114,878 had no prior acute care use (45.5%). After adjustment for age and sex, high cost user status was associated with a 14% increased odds of receiving an invasive intervention, a 15% increased odds of having major surgery, and an 8% lower odds of receiving palliative care compared to non-high cost users, but opposite when compared to patients without prior healthcare use. CONCLUSIONS: Many patients receive aggressive elements of end-of-life care during the hospitalization in which they die and a substantial number do not receive palliative care. Understanding how this care differs between those who were previously high- and non-high cost users may provide an opportunity to improve end of life care for whom better care planning and provision ought to be an equal priority.

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.

PURPOSE: Intravenous immune globulin (IVIG) may improve survival in people with septic shock. Current utilization patterns of IVIG are unknown. We sought to characterize adult patients with septic shock requiring vasopressors who received IVIG, describes IVIG regimens, and evaluate determinants of IVIG use in patients with septic shock. METHODS: We conducted a retrospective database study of adult patients with septic shock admitted to US hospitals in the Premier Healthcare Database (from July 2010 to June 2013). We described the proportion of patients with septic shock receiving IVIG, examined IVIG regimens across sites and employed random-effects multivariable regression techniques to identify predictors of IVIG use. RESULTS: Intravenous immune globulin was administered to 0.3% (n = 685) of patients with septic shock; with a median [interquartile range (IQR)] dose of 1 [0.5-1.8] g·kg-1 for a median [IQR] of 1 [1-2] day. Receipt of IVIG was less likely for Black patients (odds ratio [OR], 0.54; 95% confidence interval [CI] 0.41 to 0.72) and patients without private insurance (Medicare OR, 0.73; 95% CI 0.59 to 0.90; Medicaid OR, 0.41; 95% CI 0.30 to 0.57) and more likely for patients with immunocompromise (OR, 6.83; 95% CI 5.47 to 8.53), necrotizing fasciitis (OR, 9.78; 95% CI 6.97 to 13.72), and toxic shock (OR, 56.9; 95% CI 38.7 to 83.7). CONCLUSIONS: Intravenous immune globulin is used infrequently across the US in patients with septic shock. Regimens of IVIG in septic shock may be less intensive than those associated with a survival benefit in meta-analyses. Observed infrequent use supports apparent clinical equipoise, perhaps secondary to limitations of the primary literature. A clinical trial evaluating the role of IVIG in septic shock is needed.
RéSUMé: OBJECTIF: L'immunoglobuline intraveineuse (IGIV) peut améliorer la survie chez les personnes atteintes de choc septique. Les pratiques actuelles d'utilisation de l'IGIV sont inconnues. Nous avons cherché à caractériser les patients adultes en état de choc septique et nécessitant des vasopresseurs qui ont reçu de l'IGIV, à décrire les dosages administrés d'IGIV, et à évaluer les causes déterminantes d'une utilisation d'IGIV chez ces patients. MéTHODE: Nous avons réalisé une étude rétrospective de base de données portant sur des patients adultes atteints de choc septique admis dans des hôpitaux américains et inclus dans la base de données Premier Healthcare (de juillet 2010 à juin 2013). Nous avons décrit la proportion de patients en choc septique recevant de l'IGIV, examiné les posologies utilisées d'IGIV à travers les sites et employé des techniques de régression multivariable à effets aléatoires pour identifier les prédicteurs de l'utilisation d'IGIV. RéSULTATS: L'IGIV a été administrée à 0,3 % (n = 685) des patients présentant un choc septique, avec une dose médiane [écart interquartile (ÉIQ)] de 1 [0,51,8] g·kg-1 pour une médiane [ÉIQ] de 1 [12] jour. L'administration d'IGIV était moins probable chez les patients noirs (rapport de cotes [RC], 0,54; intervalle de confiance [IC] à 95 %, 0,41 à 0,72) et les patients sans assurance privée (RC Medicare, 0,73; IC 95 %, 0,59 à 0,90; RC Medicaid, 0,41; IC 95 %, 0,30 à 0,57) et plus probable chez les patients immunodéprimés (RC, 6,83; IC 95 %, 5,47 à 8,53), atteints de fasciite nécrosante (RC, 9,78; IC 95 %, 6,97 à 13,72), et en choc toxique (RC, 56,9; IC 95 %, 38,7 à 83,7). CONCLUSION: L'IGIV est rarement utilisée aux États-Unis chez les patients en choc septique. Les dosages d'IGIV utilisés en cas de choc septique pourraient être moins intensifs que ceux associés à un effet bénéfique en matière de survie dans les méta-analyses. L'utilisation peu fréquente observée appuie une équivalence clinique apparente, peut-être secondaire aux limites de la littérature princeps. Une étude clinique évaluant le rôle de l'IGIV dans le choc septique est nécessaire.

PURPOSE: This national survey evaluated the perceived efficacy and safety of intravenous immune globulin (IVIG) in septic shock, self-reported utilization patterns, barriers to use, the population of interest for further trials and willingness to participate in future research of IVIG in septic shock. METHODS: We conducted a cross-sectional survey of critical care and infectious diseases physicians across Canada. We summarized categorical item responses as counts and proportions. We developed a multivariable logistic regression model to identify physician-level predictors of IVIG use in septic shock. RESULTS: Our survey was disseminated to 674 eligible respondents with a final response rate of 60%. Most (91%) respondents reported having prescribed IVIG to patients with septic shock at least once, 86% for septic shock due to necrotizing fasciitis, 52% for other bacterial toxin-mediated causes of septic shock, and 5% for undifferentiated septic shock. The majority of respondents expressed uncertainty regarding the impact of IVIG on mortality (97%) and safety (95%) in septic shock. Respondents were willing to participate in further IVIG research with 98% stating they would consider enrolling their patients into a trial of IVIG in septic shock. Familiarity with published evidence was the single greatest predictor of IVIG use in septic shock (odds ratio, 10.2; 95% confidence interval, 3.4 to 30.5; P < 0.001). CONCLUSIONS: Most Canadian critical care and infectious diseases specialist physicians reported previous experience using IVIG in septic shock. Respondents identified inadequacy of existing research as the greatest barrier to routine use of IVIG in septic shock. Most respondents support the need for further studies on IVIG in septic shock, and would consider enrolling their own patients into a trial of IVIG in septic shock.
RéSUMé: OBJECTIF : Cette enquête nationale a évalué l'efficacité et l'innocuité perçues des immunoglobulines intraveineuses (IgIV) dans le contexte du choc septique, les habitudes d'utilisation autodéclarées, les obstacles à l'utilisation de cette modalité, les populations à explorer pour des études futures et la volonté de participer aux recherches futures sur les IgIV et le choc septique. MéTHODE : Nous avons mené une enquête transversale auprès de médecins intensivistes et spécialistes des maladies infectieuses au Canada. Nous avons résumé les réponses de chaque point catégorique en tant que dénombrement et proportions. Nous avons mis au point un modèle de régression logistique multivariée afin d'identifier les prédicteurs, au niveau des médecins, d'une utilisation des IgIV en cas de choc septique. RéSULTATS : Notre sondage a été acheminé à 674 médecins admissibles et nous avons obtenu un taux de réponse final de 60 %. La plupart (91%) des répondants ont indiqué avoir prescrit des IgIV aux patients en choc septique au moins une fois, 86 % pour un choc septique dû à une fasciite nécrosante, 52 % pour des chocs septiques d'autres étiologies médiées par des toxines bactériennes, et 5 % dans des cas de choc septique non différencié. La majorité des répondants ont exprimé de l'incertitude quant à l'incidence des IgIV sur la mortalité (97 %) et l'innocuité (95 %) lors de choc septique. Les répondants étaient disposés à participer à d'autres recherches sur les IgIV, 98 % déclarant qu'ils envisageraient d'inscrire leurs patients à une étude sur les IgIV et le choc septique. La familiarité avec les données probantes publiées était le plus grand prédicteur d'utilisation d'IgIV dans un contexte de choc septique (rapport de cotes, 10,2; intervalle de confiance à 95 %, 3,4 à 30,5; P < 0,001). CONCLUSION : La plupart des médecins intensivistes et spécialistes des maladies infectieuses canadiens ont rapporté avoir une expérience antérieure d'utilisation d'IgIV en cas de choc septique. Les répondants ont identifié l'insuffisance de la recherche existante comme le plus grand obstacle à l'utilisation systématique d'IgIV dans les cas de choc septique. La plupart des répondants appuient la nécessité d'études plus approfondies sur les IgIV et le choc septique et envisageraient d'inscrire leurs propres patients à une étude sur les IgIV dans un contexte de choc septique.

BACKGROUND: Inpatient palliative care is associated with lower inpatient costs; however, this has yet to be studied using a more nuanced, multi-tiered measure of inpatient palliative care and a national population-representative dataset. Using a population-based cohort of Canadians who died in hospital, our objectives were to: describe patients' receipt of palliative care and active interventions in their terminal hospitalization; and examine the relationship between inpatient palliative care and hospitalization costs. METHODS: Retrospective cohort study using data from the Discharge Abstract Database in Canada between fiscal years 2012 and 2015. The cohort were Canadian adults (age ≥ 18 years) who died in hospital between April 1st, 2012 and March 31st, 2015 (N = 250,640). The exposure was level of palliative care involvement defined as: medium-high, low, or no palliative care. The main measure was acute care costs calculated using resource intensity weights multiplied by the cost of standard hospital stay, represented in 2014 Canadian dollars (CAD). Descriptive statistics were represented as median (IQR), and n(%). We modelled cost as a function of palliative care using a gamma generalized estimating equation (GEE) model, accounting for clustering by hospital. RESULTS: There were 250,640 adults who died in hospital. Mean age was 76 (SD 14), 47% were female. The most common comorbidities were: metastatic cancer (21%), heart failure (21%), and chronic obstructive pulmonary disease (16%). Of the decedents, 95,450 (38%) had no palliative care involvement, 98,849 (38%) received low involvement, and 60,341 (24%) received medium to high involvement. Controlling for age, sex, province and predicted hospital mortality risk at admission, the cost per day of a terminal hospitalization was: $1359 (95% CI 1323: 1397) (no involvement), $1175 (95% CI 1146: 1206) (low involvement), and $744 (95% CI 728: 760) (medium-high involvement). CONCLUSIONS: Increased involvement of palliative care was associated with lower costs. Future research should explore whether this relationship holds for non-terminal hospitalizations, and whether palliative care in other settings impacts inpatient costs.

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.

Investigating clustered data requires consideration of the variation across clusters, including consideration of the component of the total individual variance that is at the cluster level. The median odds ratio and analogues are useful intuitive measures available to communicate variability in outcomes across clusters using the variance of random intercepts from a multilevel regression model. However, the median odds ratio cannot describe variability across clusters for different patient subgroups because the random intercepts do not vary by subgroup. To empower investigators interested in equity and other applications of this scenario, we describe an extension of the median odds ratio to multilevel regression models employing both random intercepts and random coefficients. By example, we conducted a retrospective cohort analysis of variation in care limitations (goals of care preferences) according to ethnicity in patients admitted to intensive care. Using mixed-effects logistic regression clustered by hospital, we demonstrated that patients of non-Caucasian ethnicity were less likely to have care limitations but experienced similar variability across hospitals. Limitations of the extended median odds ratio include the large sample sizes and computational power needed for models with random coefficients. This extension of the median odds ratio to multilevel regression models with random coefficients will provide insight into cluster-level variability for researchers interested in equity and other phenomena where variability by patient subgroup is important.

BACKGROUND: Little is known about documentation during transitions of patient care between clinical specialties. Therefore, we examined the focus, structure and purpose of physician progress notes for patients transferred from the intensive care unit (ICU) to hospital ward to identify opportunities to improve communication breaks. METHODS: This was a prospective cohort study in ten Canadian hospitals. We analyzed physician progress notes for consenting adult patients transferred from a medical-surgical ICU to hospital ward. The number, length, legibility and content of notes was counted and compared across care settings using mixed-effects linear regression models accounting for clustering within hospitals. Qualitative content analyses were conducted on a stratified random sample of 32 patients. RESULTS: A total of 447 patient medical records that included 7052 progress notes (mean 2.1 notes/patient/day 95% CI 1.9-2.3) were analyzed. Notes written by the ICU team were significantly longer than notes written by the ward team (mean lines of text 21 vs. 15, p < 0.001). There was a discrepancy between documentation of patient issues in the last ICU and first ward notes; mean agreement of patient issues was 42% [95% CI 31-53%]. Qualitative analyses identified eight themes related to focus (central point - e.g., problem list), structure (organization, - e.g., note-taking style), and purpose (intention - e.g., documentation of patient course) of the notes that varied across clinical specialties and physician seniority. CONCLUSIONS: Important gaps and variations in written documentation during transitions of patient care between ICU and hospital ward physicians are common, and include discrepancies in documentation of patient information.

OBJECTIVE: Very elderly persons admitted to ICUs are at high risk of death. To document life-sustaining interventions (mechanical ventilation, vasopressors, renal replacement therapy) provided in the ICU and outcomes of care. DESIGN: Multicenter, prospective cohort study. SETTING: ICUs of 24 Canadian hospitals. PARTICIPANTS/SETTING: Patients 80 years old or older admitted to the ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: One thousand six hundred seventy-one patients were included. The average age of the cohort was 85 years (range, 80-100 yr). Median total length of stay in ICU was 4 days (interquartile range, 2-8 d) and in hospital was 17 days (interquartile range, 8-33 d). Of all patients included, 502 (30%) stayed in ICU for 7 days or more and 344 (21%) received some form of life-sustaining treatment for at least 7 days. ICU and hospital mortality were 22% and 35%, respectively. For nonsurvivors, the median time from ICU admission to death was 10 days (interquartile range, 3-20 d). Of those who died (n = 5 85), 289 (49%) died while receiving mechanical ventilation, vasopressors, or dialysis. The presence of frailty or advance directives had little impact on limiting use of life-sustaining treatments or shortening the time from admission to death. CONCLUSIONS: In this multicenter study, one third of very elderly ICU patients died in hospital, many after a prolonged ICU stay while continuing to receive aggressive life-sustaining interventions. These findings raise questions about the use of critical care at the end of life for the very elderly.

OBJECTIVE: Many healthcare workers are concerned about the provision of nonbeneficial treatment in the acute care setting. We sought to explore the perceptions of acute care practitioners to determine whether they perceived nonbeneficial treatment to be a problem, to generate an acceptable definition of nonbeneficial treatment, to learn about their perceptions of the impact and causes of nonbeneficial treatment, and the ways that they feel could reduce or resolve nonbeneficial treatment. DESIGN: National, bilingual, cross-sectional survey of a convenience sample of nursing and medical staff who provide direct patient care in acute medical wards or ICUs in Canada. MAIN RESULTS: We received 688 responses (response rate 61%) from 11 sites. Seventy-four percent of respondents were nurses. Eighty-two percent of respondents believe that our current means of resolving nonbeneficial treatment are inadequate. The most acceptable definitions of nonbeneficial treatment were "advanced curative/life-prolonging treatments that would almost certainly result in a quality of life that the patient has previously stated that he/she would not want" (88% agreement) and "advanced curative/life-prolonging treatments that are not consistent with the goals of care (as indicated by the patient)" (83% agreement). Respondents most commonly believed that nonbeneficial treatment was caused by substitute decision makers who do not understand the limitations of treatment, or who cannot accept a poor prognosis (90% agreement for each cause), and 52% believed that nonbeneficial treatment was "often" or "always" continued until the patient died or was discharged from hospital. Respondents believed that nonbeneficial treatment was a common problem with a negative impact on all stakeholders (> 80%) and perceived that improved advance care planning and communication training would be the most effective (92% and 88%, respectively) and morally acceptable (95% and 92%, respectively) means to resolve the problem of nonbeneficial treatment. CONCLUSIONS: Canadian nurses and physicians perceive that our current means of resolving nonbeneficial treatment are inadequate, and that we need to adopt new techniques of resolving nonbeneficial treatment. The most promising strategies to reduce nonbeneficial treatment are felt to be improved advance care planning and communication training for healthcare professionals.

BACKGROUND: Little is known about the perspectives and experiences of family members of very elderly patients who are admitted to the intensive care unit. AIM: To describe family members' perspectives about care provided to very elderly critically ill patients. DESIGN: Multicenter, prospective, cohort study. PARTICIPANTS AND SETTING: In total, 535 family members of patients aged 80 years or older admitted to 22 intensive care units for more than 24 h. RESULTS: Family members reported that the "patient be comfortable and suffer as little as possible" was their most important value and "the belief that life should be preserved at all costs" was their least important value considered in making treatment decisions. Most family members (57.9%) preferred that life support be used for their family member, whereas 24.1% preferred comfort measures only, and 14.4% were unsure of their treatment preferences. Only 57.3% reported that a doctor had talked to them about treatment options for the patient. Overall, 29.7% of patients received life-sustaining treatments for more than 7 days and 50.3% of these died in hospital. Families were most satisfied with the skill and competency of nurses and least satisfied with being included and supported in the decision-making process and with their sense of control over the patient's care. CONCLUSION: There is incongruity between family values and preferences for end-of-life care and actual care received for very elderly patients who are admitted to the intensive care unit. Deficiencies in communication and decision-making may be associated with prolonged use of life-sustaining treatments in very elderly critically ill patients, many of whom ultimately die.

OBJECTIVE: Controversies regarding the process and timing of the determination of death for controlled organ donation after circulatory death persist. This study assessed the feasibility of conducting a prospective, observational study of continuous monitoring of vital signs for 30 minutes after the clinical determination of death in five Canadian ICUs. Waveform data were analyzed. DESIGN: Prospective observational cohort study. SETTING: One pediatric and four adult Canadian ICUs. PATIENTS: One month of age or older, admitted to the ICU, and for whom a consensual decision to withdraw life-sustaining therapies had been made, with an anticipation of imminent death. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Invasive arterial blood pressure, electrocardiogram, and oxygen saturation plethysmography activity were recorded and reviewed for 30 minutes after declaration of death. Feasibility was assessed (recruitment, consent rate, protocol compliance, and staff satisfaction). Of 188 subjects screened over 16 months, 41 subjects were enrolled (87% consent rate). Data collection was complete for 30 subjects (73% protocol compliance). In four subjects, arterial blood pressure resumed following cessation of activity. The longest period of cessation of arterial blood pressure before resumption was 89 seconds. The duration of resumed activity ranged from 1 to 172 seconds. No cases of sustained resumption of arterial blood pressure activity were recorded, and no instances of clinical autoresuscitation were reported. In nearly all patients (27 of 30), electrocardiogram activity continued after the disappearance of arterial blood pressure. CONCLUSIONS: This is the first observational study to prospectively collect waveform data for 30 minutes after the declaration of death. A future larger study may support initial data suggesting that circulatory function does not resume after more than 89 seconds of absence. Furthermore, persistence of cardiac electrical activity with the documented absence of circulation may not be relevant to declaration of death.

RATIONALE: Women, older individuals, and racial and ethnic minority groups are often underrepresented in research studies. OBJECTIVES: We evaluated the demographics and diversity of participants enrolled in randomized trials (RCTs) and observational studies published by investigators in association with the Canadian Critical Care Trials Group (CCCTG). METHODS: Quantitative content analysis of peer reviewed RCTs and observational studies from December 1994 to December 2022. For each publication, we extracted participant demographic variables, including sex/gender, age, race or ethnicity, sexual orientation, pregnancy status, language proficiency, income/financial status, housing, education, disability, and geography. RESULTS: 120 publications (28 RCTs, 92 observational studies) enrolled 211,144 participants. Most (107/120, 89.2%) were multicenter studies, and 70% (84/120) were conducted exclusively in Canadian centers; 77.5% (93/120) studies enrolled adult participants, and 19.2% (23/120) enrolled pediatric participants. All studies reported participant mean or median age, 118 (98.3%) reported binary sex or gender, and 9 (7.5%) reported race or ethnicity. No justification was provided in 35 studies which listed pregnancy as an exclusion. There was infrequent reporting of housing (N=4), employment (N=2), income (N=2), and education (N=1). No studies reported language proficiency, sexual orientation, disability or geography of participants. Of the studies reporting gender, women/girls comprised 42.3% participants (range 8.9 to 67.7%). Within 9 studies reporting race or ethnicity of 2950 participants, 59.7% were white, 8% South Asian, 7% Indigenous, 3% Asian, 1% Black, 14% unknown, and 6% 'Other'. CONCLUSIONS: Research publications from the CCCTG infrequently report important participant demographics, and diversity of research participants is disproportionate compared to Canadian societal demographics.
