RESUMO

PURPOSE: Agitation is a common behavioural problem following traumatic brain injury (TBI). Intensive care unit (ICU) physicians' perspectives regarding TBI-associated agitation are unknown. Our objective was to describe physicians' beliefs and perceived importance of TBI-associated agitation in critically ill patients. METHODS: Following current standard guidance, we built an electronic, self-administrated, 42-item survey, pretested it for reliability and validity, and distributed it to 219 physicians working in 18 ICU level-1 trauma centres in Canada. We report the results using descriptive statistics. RESULTS: The overall response rate was 93/219 (42%), and 76/93 (82%) respondents completed the full survey. Most respondents were men with ten or more years of experience. Respondents believed that pre-existing dementia (90%) and regular recreational drug use (86%) are risk factors for agitation. Concerning management, 91% believed that the use of physical restraints could worsen agitation, 90% believed that having family at the bedside reduces agitation, and 72% believed that alpha-2 adrenergic agonists are efficacious for managing TBI agitation. Variability was observed in beliefs on epidemiology, sex, gender, age, socioeconomic status, and other pharmacologic options. Respondents considered TBI agitation frequent enough to justify the implementation of management protocols (87%), perceived the current level of clinical evidence on TBI agitation management to be insufficient (84%), and expressed concerns about acute and long-term detrimental outcomes and burden to patients, health care professionals, and relatives (85%). CONCLUSION: Traumatic brain injury-associated agitation in critically ill patients was perceived as an important issue for most ICU physicians. Physicians agreed on multiple approaches to manage TBI-associated agitation although agreement on epidemiology and risk factors was variable.


RéSUMé: OBJECTIF: L'agitation est un problème de comportement courant à la suite d'un traumatisme crânien (TC). Le point de vue des médecins des unités de soins intensifs (USI) sur l'agitation associée aux traumatismes crâniens est inconnu. Notre objectif était de décrire les croyances et l'importance perçue par les médecins de l'agitation associée aux traumatismes crâniens chez les patient·es gravement malades. MéTHODE: Conformément aux lignes directrices standard actuelles, nous avons élaboré un sondage électronique auto-administré de 42 questions, l'avons testé au préalable pour en vérifier la fiabilité et la validité, et l'avons distribué à 219 médecins travaillant dans les USI de 18 centres de traumatologie de niveau 1 au Canada. Les résultats sont présentés à l'aide de statistiques descriptives. RéSULTATS: Le taux de réponse global a été de 93 sur 219 (42 %) et 76 sur 93 (82 %) personnes interrogées ont répondu à l'ensemble du sondage. La plupart des répondant·es étaient des hommes comptant dix ans ou plus d'expérience. Les répondant·es sont d'avis que la démence préexistante (90 %) et la consommation régulière de drogues à des fins récréatives (86 %) sont des facteurs de risque d'agitation. En ce qui concerne la prise en charge, 91 % des répondant·es estiment que l'utilisation de contentions physiques peut aggraver l'agitation, 90 % croient que le fait d'avoir de la famille au chevet du patient ou de la patiente réduit l'agitation et 72 % pensent que les agonistes alpha-2 adrénergiques sont efficaces pour gérer l'agitation causée par les traumatismes crâniens. Une variabilité a été observée dans les croyances concernant l'épidémiologie, le sexe, le genre, l'âge, le statut socio-économique et d'autres options pharmacologiques. Les répondant·es considéraient que l'agitation liée aux traumatismes crâniens était suffisamment fréquente pour justifier la mise en œuvre de protocoles de prise en charge (87 %), estimaient que le niveau actuel de données probantes cliniques sur la prise en charge de l'agitation causée par un traumatisme crânien était insuffisant (84 %), et se sont dit·es préoccupé·es par les conséquences préjudiciables aiguës et à long terme et par le fardeau pour les patient·es, les professionnel·les de la santé et les proches (85 %). CONCLUSION: L'agitation associée à un traumatisme crânien chez les patient·es gravement malades était perçue comme un problème important pour la plupart des médecins des soins intensifs. Les médecins s'entendaient sur plusieurs approches pour gérer l'agitation associée aux traumatismes crâniens, bien que l'accord sur l'épidémiologie et les facteurs de risque était variable.

RESUMO

Importance: Blood collection for laboratory testing in intensive care unit (ICU) patients is a modifiable contributor to anemia and red blood cell (RBC) transfusion. Most blood withdrawn is not required for analysis and is discarded. Objective: To determine whether transitioning from standard-volume to small-volume vacuum tubes for blood collection in ICUs reduces RBC transfusion without compromising laboratory testing procedures. Design, Setting, and Participants: Stepped-wedge cluster randomized trial in 25 adult medical-surgical ICUs in Canada (February 5, 2019 to January 21, 2021). Interventions: ICUs were randomized to transition from standard-volume (n = 10 940) to small-volume tubes (n = 10 261) for laboratory testing. Main Outcomes and Measures: The primary outcome was RBC transfusion (units per patient per ICU stay). Secondary outcomes were patients receiving at least 1 RBC transfusion, hemoglobin decrease during ICU stay (adjusted for RBC transfusion), specimens with insufficient volume for testing, length of stay in the ICU and hospital, and mortality in the ICU and hospital. The primary analysis included patients admitted for 48 hours or more, excluding those admitted during a 5.5-month COVID-19-related trial hiatus. Results: In the primary analysis of 21 201 patients (mean age, 63.5 years; 39.9% female), which excluded 6210 patients admitted during the early COVID-19 pandemic, there was no significant difference in RBC units per patient per ICU stay (relative risk [RR], 0.91 [95% CI, 0.79 to 1.05]; P = .19; absolute reduction of 7.24 RBC units/100 patients per ICU stay [95% CI, -3.28 to 19.44]). In a prespecified secondary analysis (n = 27 411 patients), RBC units per patient per ICU stay decreased after transition from standard-volume to small-volume tubes (RR, 0.88 [95% CI, 0.77 to 1.00]; P = .04; absolute reduction of 9.84 RBC units/100 patients per ICU stay [95% CI, 0.24 to 20.76]). Median decrease in transfusion-adjusted hemoglobin was not statistically different in the primary population (mean difference, 0.10 g/dL [95% CI, -0.04 to 0.23]) and lower in the secondary population (mean difference, 0.17 g/dL [95% CI, 0.05 to 0.29]). Specimens with insufficient quantity for analysis were rare (≤0.03%) before and after transition. Conclusions and Relevance: Use of small-volume blood collection tubes in the ICU may decrease RBC transfusions without affecting laboratory analysis.

RESUMO

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.

RESUMO

BACKGROUND: In the setting of the COVID-19 pandemic, the conduct of elective cancer surgery has become an issue because of the need to balance the requirement to treat patients with the possibility of transmission of the virus by asymptomatic carriers. A particular concern is the potential for viral transmission by way of aerosol which may be generated during perioperative care. There are currently no guidelines for the conduct of elective lung resection surgery in this context. METHODS: A working group composed of 1 thoracic surgeon, 2 anesthesiologists and 1 critical care specialist assessed the risk for aerosol during lung resection surgery and proposed steps for mitigation. After external review, a final draft was approved by the Committee for the Governance of Perioperative and Surgical Activities of the Hôpital Maisonneuve-Rosemont, in Montreal, Canada. RESULTS: The working group divided the risk for aerosol into 6 time-points: (1) intubation and extubation; (2) Lung isolation and patient positioning; (3) access to the chest; (4) conduct of the surgical procedure; (5) procedure termination and lung re-expansion; (6) chest drainage. Mitigating strategies were proposed for each time-point. CONCLUSIONS: The situation with COVID-19 is an opportunity to re-evaluate operating room protocols both for the purposes of this pandemic and similar situations in the future. In the context of lung resection surgery, specific time points during the procedure seem to pose specific risks for the genesis of aerosol and thus should be the focus of attention.

RESUMO

PURPOSE: Identifying patients at risk of postoperative complications and trying to prevent these complications are the essence of preoperative evaluation. While not overtly frail or disabled, vulnerable patients with mild frailty may be missed by routine assessments and may still have a worse postoperative course. METHODS: We performed a prospective cohort study evaluating vulnerability in older patients undergoing elective surgery. Vulnerability was assessed using the Clinical Frailty Scale. Our primary outcome was postoperative hospital length of stay (LOS) and our secondary outcome was non-home hospital discharge. We performed multivariable analyses to assess the association between vulnerability and our primary and secondary outcome. RESULTS: Between 1 January 2017 and 1 January 2018, 271 older patients with a median [interquartile range (IQR)] age of 72 [69-76] yr underwent frailty assessment prior to surgery. Eighty-eight (32.5%) of the cohort were classified as vulnerable. The median [IQR] duration of hospital LOS was 4 [2-7] days for vulnerable patients, 4 [2-6] days for robust patients, and 7 [3-10] days for frail patients. After adjusting for confounders, hospital LOS was not longer for vulnerable patients than for robust patients, but was associated with a higher rate of non-home discharge (odds ratio, 3.7; 95% confidence interval, 1.1 to 12.9; P = 0.04). CONCLUSIONS: Vulnerability was not associated with a longer hospital LOS but with higher risk of non-home discharge. Vulnerable patients might benefit from early identification and advanced planning with earlier transfer to rehabilitation centres.


RéSUMé: OBJECTIF: L'identification des patients à risque de complications postopératoires et la prévention de ces complications constituent le fondement de l'évaluation préopératoire. Sans être ouvertement fragiles ou handicapés, les patients vulnérables avec une fragilité légère pourraient passer entre les mailles des évaluations de routine et tout de même souffrir d'un parcours postopératoire plus difficile. MéTHODE: Nous avons réalisé une étude de cohorte prospective évaluant la vulnérabilité des patients âgés subissant une chirurgie élective. La vulnérabilité a été évaluée à l'aide de l'Échelle Clinical Frailty Scale. Notre critère d'évaluation principal était la durée de séjour hospitalier postopératoire; notre critère d'évaluation secondaire était le congé de l'hôpital sans retour au foyer. Nous avons réalisé des analyses multivariées afin d'évaluer l'association entre la vulnérabilité et nos critères d'évaluation principal et secondaire. RéSULTATS: Entre le 1er janvier 2017 et le 1er janvier 2018, 271 patients d'un âge médian [écart interquartile (ÉIQ)] de 72 [69­76] ans ont passé une évaluation de fragilité avant leur chirurgie. Quatre-vingt-huit personnes (32,5 %) de la cohorte ont été catégorisées comme vulnérables. La durée médiane [ÉIQ] de séjour hospitalier était de 4 [2­7] jours pour les patients vulnérables, 4 [2­6] pour les patients robustes, et 7 [3­10] pour les patients fragiles. Après l'ajustement pour tenir compte des facteurs confondants, la durée de séjour hospitalier n'était pas plus longue pour les patients vulnérables que pour les patients robustes, mais était associée à un taux plus élevé de congé sans retour au foyer (rapport de cotes, 3,7; intervalle de confiance 95 %, 1,1 à 12,9; P = 0,04). CONCLUSION: La vulnérabilité n'a pas été associée à une durée de séjour hospitalier plus longue mais à un risque plus élevé de congé sans retour au foyer. Les patients vulnérables pourraient bénéficier d'une identification précoce et d'une planification avancée avec un transfert plus rapide vers les centres de réadaptation.

RESUMO

PURPOSE: Restrictive fluid management strategies have been proposed to reduce complications in liver transplant recipients. We conducted a systematic review to evaluate the effects of restrictive perioperative fluid management strategies, compared with liberal ones, on postoperative outcomes in adult liver transplant recipients. Our primary outcome was acute kidney injury (AKI). Our secondary outcomes were bleeding, mortality, and other postoperative complications. SOURCE: We searched major databases (CINAHL, EMB Reviews, EMBASE, MEDLINE, and the grey literature) from their inception to 10 July 2018 for randomized-controlled trials (RCTs) and observational studies comparing two fluid management strategies (or observational studies reporting two outcomes with available data on fluid volume received) in adult liver transplant recipients. Study selection, data abstraction, and risk of bias assessment were performed by at least two investigators. Data from RCTs were pooled using risk ratios (RR) and mean differences (MD) with random-effect models. PRINCIPAL FINDINGS: We found seven RCTs and 29 observational studies. Based on RCTs, fluid management strategies did not have any effect on AKI, mortality, or any other postoperative complications. Intraoperative RCTs suggested that a restrictive fluid management strategy reduced pulmonary complications (RR, 0.69; 95% confidence interval [CI], 0.47 to 0.99; n = 283; I2 = 27%), duration of mechanical ventilation (MD, -13.04 hr; 95% CI, -22.2 to -3.88; n = 130; I2 = 0%) and blood loss (MD, -1.14 L; 95% CI, -1.72 to -0.57; n = 151; I2 = 0%). CONCLUSION: Based on low or very low levels of evidence, we did not find any association between restrictive fluid management strategies and AKI, but we observed possible protective effects of intraoperative restrictive fluid management strategies on other outcomes.

RESUMO

PURPOSE: Collection and analysis of health data are crucial to achieving high-quality clinical care, research, and quality improvement. This review explores existing hospital, regional, provincial and national data platforms in Canada to identify gaps and barriers, and recommend improvements for data science. SOURCE: The Canadian Critical Care Trials Group and the Canadian Critical Care Translational Biology Group undertook an environmental survey using list-identified names and keywords in PubMed and the grey literature, from the Canadian context. Findings were grouped into sections, corresponding to geography, purpose, and patient sub-group initiatives, using a narrative qualitative approach. Emerging themes, impressions, and recommendations towards improving data initiatives were generated. PRINCIPAL FINDINGS: In Canada, the Canadian Institute for Health Information Discharge Abstract Database contains high-level clinical data on every adult and child discharged from acute care facilities; however, it does not contain data from Quebec, critical care-specific severity of illness risk-adjustment scores, physiologic data, or data pertaining to medication use. Provincially mandated critical care platforms in four provinces contain more granular data, and can be used to risk adjust and link to within-province data sets; however, no inter-provincial collaborative mechanism exists. There is very limited infrastructure to collect and link biological samples from critically ill patients nationally. Comprehensive international clinical data sets may inform future Canadian initiatives. CONCLUSION: Clinical and biological data collection among critically ill patients in Canada is not sufficiently coordinated, and lags behind other jurisdictions. An integrated and inclusive critical care data platform is a key clinical and scientific priority in Canada.

RESUMO

OBJECTIVES: Postoperative pulmonary complications increase mortality, length, and cost of hospitalization. A better diaphragmatic strength may help face an increased work of breathing postoperatively. We, therefore, sought to determine if a low preoperative diaphragm thickening fraction (TFdi) determined by ultrasonography helped predict the occurrence of postoperative pulmonary complications after cardiac surgery independently of indicators of frailty, sarcopenia, and pulmonary function. DESIGN: Prospective observational cohort study. SETTING: Montreal Heart Institute, an academic cardiac surgery center in Canada. PATIENTS: Adults undergoing nonemergency cardiac surgery. INTERVENTIONS: We measured the preoperative thickness of the right and left hemidiaphragms at their zone of apposition at end-expiration (Tdi,ee) and peak-inspiration (Tdi,ei) with ultrasonography. Maximal thickening fraction of the diaphragm during inspiration (TFdi,max) was calculated using the following formula: TFdi,max = (Tdi,ei-Tdi,ee)/Tdi,ee. We also evaluated other potential risk factors including demographic parameters, comorbidities, Clinical Frailty Scale, grip strength, 5-meter walk test, and pulmonary function tests. We repeated TFdi,max measurements within 24 hours of extubation. The primary composite outcome of this study was the occurrence of postoperative pulmonary complications, defined as pneumonia, clinically significant atelectasis, or prolonged mechanical ventilation (> 24 hr). MEASUREMENT AND MAIN RESULTS: Of the 115 patients included, 34 (29.6%) developed postoperative pulmonary complications, including two with pneumonia, four with prolonged mechanical ventilation, and 32 with clinically significant atelectasis. Those with postoperative pulmonary complications had prolonged ICU and hospital length of stays. They had a lower TFdi,max (37% [interquartile range, 31-45%] vs 44% [interquartile range, 33-58%]; p = 0.03). In multiple logistic regression, a TFdi,max less than 38.1% was associated with postoperative pulmonary complications (odds ratio, 4.9; 95% CI, 1.81-13.50; p = 0.002). All patients who developed pneumonia or prolonged mechanical ventilation had a TFdi,max less than 38.1%. Respiratory rate and diabetes were also independently associated with postoperative pulmonary complications, while pulmonary function tests and the assessed indicators of frailty and sarcopenia were not. CONCLUSIONS: A low preoperative TFdi,max can help to identify patients at increased risk of postoperative pulmonary complications after cardiac surgery.

RESUMO

OBJECTIVES: Critical illness is often associated with painful procedures and prolonged opioid infusions, raising the concern that chronic opioid users may be exposed to escalating doses that are continued after hospital discharge. We sought to assess patterns of opioid use after intensive care among elderly patients identified as chronic opioid users prior to hospitalization. DESIGN: Population-based cohort study. SETTING: All adult ICUs in the province of Ontario, Canada. PARTICIPANTS: Elderly patients (> 65 yr) admitted to ICUs between April 2002 and March 2015 who also survived to day 180 after hospital discharge, identified as chronic opioid users prior to hospitalization. EXPOSURE: Chronic opioid use in the year before hospital admission, as well as a filled opioid prescription with a duration covering the day of hospital admission. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the proportion of patients who filled an opioid prescription with a duration covering day 180 after hospital discharge; secondary outcome was the difference in morphine equivalent daily dosage at day 180 after discharge compared with the amount prescribed prior to hospital admission. Of 496,985 elderly admissions to ICUs, 19,584 (3.9%) were chronic opioid users before hospitalization who also survived to day 180 after hospital discharge. The median daily dose of opioid prescriptions filled before hospital admission was 32.1 mg morphine equivalent (interquartile range, 17.5-75.0 mg morphine equivalent). Among these survivors, 63.3% had at least one opioid prescription filled with a duration covering day 180; 22.0% had filled prescriptions for a higher daily morphine equivalent dose compared with prehospitalization, 19.8% were unchanged, 21.5% had a lower dose, and 36.7% had no prescription filled. The majority of reduction was in prescriptions for codeine and oxycodone. CONCLUSIONS: Among chronic opioid users, hospitalization with critical illness was not associated with substantial increases in opioids prescribed in the 6 months following hospitalization.

RESUMO

BACKGROUND: Total joint replacement procedures are increasing in number because of population aging and osteoarthritis development. Defined as a lack of physiological reserves and the inability to adequately respond to external stressors, frailty may be more common than expected in older patients with degenerative arthritis awaiting total joint replacements. The aim of the present study was to assess associations between frailty and adverse outcomes, frailty prevalence among elderly patients awaiting elective TJR, and agreement between 2 frailty screening instruments. METHODS: We undertook a prospective, observational, pilot study in our institution. We enrolled patients 65 years or older who were awaiting elective knee or hip replacement surgery and evaluated them in our preoperative clinic with planned postoperative hospital length of stay greater than 24 h. Patients were asked to grade their perceived well-being on the Clinical Frailty Scale and to answer questions on the FRAIL Scale. RESULTS: The Clinical Frailty Scale classified 40 patients (45.9%) as robust, 43 patients (49.4%) as prefrail and 4 patients (4.5%) as frail, while the FRAIL Scale categorized 12 patients (13.7%) as robust, 54 patients (62.0%) as prefrail, and 20 patients (22.9%) as frail. Robustness, ascertained on the Clinical Frailty Scale was, while the FRAIL Scale was not, significantly associated with shorter hospital length of stay and fewer discharges to the rehabilitation center. Both scales showed moderate mutual agreement. CONCLUSION: Screening for frailty identified between 5% and 10% of patients at risk of adverse outcomes. The Clinical Frailty Scale was, while the FRAIL scale was not, significantly associated with hospital length of stay and discharge to rehabilitation center in our cohort of total joint replacement patients.

RESUMO

OBJECTIVES: To analyze the effect of treating metabolic syndrome (MetS) on further kidney function decline in patients with early-stage chronic kidney disease (CKD). METHODS: In a study period of 24 months, 162 patients with early stage CKD were enrolled. Baseline and follow-up data related to the occurrence of MetS and glomerular filtration rate (GFR) were assessed. Subjects were classified into controlled MetS (group 1) and uncontrolled MetS (group 2). Furthermore, they were subdivided into four subgroups: (A) controlled MetS at baseline and at follow-up, (B) uncontrolled MetS at baseline but controlled MetS at follow-up visits, (C) controlled MetS at baseline but uncontrolled MetS at follow-up visits, and (D) uncontrolled MetS at baseline and follow-up visits. RESULTS: Final GFR was lower in group 2 versus group 1 (69.21 ± 20.20 vs. 82.86 ± 22.33 mL/min/1.73 m(2), p <0.001). The presence of MetS had high risk to develop late-stage CKD (HR = 3.279, 95% CI: 1.545-6.958, p = 0.002). Moreover, subgroup D (HR = 2.982, 95% CI: 1.287-6.908, p = 0.011) and the presence of three (p = 0.026) or four (p = 0.049) metabolic components had high risk to develop late-stage CKD. CONCLUSION: Treating MetS slows CKD progression in patients with early-stage of CKD.

RESUMO

Thrombotic microangiopathy (TMA) is rarely associated with Sjögren's syndrome (SS). This is the first documented case of a patient undergoing chronic hemodialysis with SS who developed TMA. TMA is an infrequent, life-threatening multisystem disorder characterized by microangiopathic hemolytic anemia and thrombocytopenia, accompanied by microvascular thrombosis that causes variable degrees of tissue ischemia and infarction. It is important to make a quick diagnosis of TMA to cure the reported case as early as possible. The patients with TMA should be diagnosed quickly, and in this case plasma exchange and corticosteroids in combination with cyclophosphamide have been associated with a recurrence free period. Cyclophosphamide has led to the development of treatment protocols using alternative immunosuppressive agents in patients with SS showing a poor response to plasmapheresis and potentially life-threatening manifestations. Further research is required to ascertain the sensitivity, specificity, efficacy, timing, cost-benefit ratio, and necessity of cyclophosphamide in the setting of TMA complicating SS.

RESUMO

OBJECTIVES: Older adults may be under-represented in critical care research, and results may not apply to this specific population. Our primary objective was to evaluate the prevalence of inclusion of older adults across critical care trials focused on common ICU conditions or interventions. Our secondary objective was to evaluate whether older age was used as a stratification variable for randomization or outcome analysis. DESIGN SETTING AND SUBJECTS: We performed a systematic review of previously published systematic reviews of randomized controlled trials (RCTs) in critical care. We searched PubMed, Ovid, CENTRAL, and Cochrane from 2009 to 2022. Systematic reviews of any interventions across five topics: acute respiratory distress syndrome (ARDS), sepsis/shock, nutrition, sedation, and mobilization were eligible. MAIN RESULTS: We identified 216 systematic reviews and included a total of 253 RCTs and 113,090 patients. We extracted baseline characteristics and the reported proportion of older adults. We assessed whether any upper age limit was an exclusion criterion for trials, whether age was used for stratification during randomization or data analysis, and if age-specific subgroup analysis was present. The most prevalent topic was sepsis (78 trials, 31%), followed by nutrition (62 trials, 25%), ARDS (39 trials, 15%), mobilization (38 trials, 15%), and sedation (36 trials, 14%). Eighteen trials (7%) had exclusion criteria based on older age. Age distribution with information on older adults prevalence was given in six trials (2%). Age was considered in the analysis of ten trials (5%) using analytic methods to evaluate the outcome stratified by age. Conclusions: In this systematic review, the proportion of older critically ill patients is undetermined, and it is unclear how age is or is not an effect modifier or to what extent the results are valid for older adult groups. Reporting age is important to guide clinicians in personalizing care. These results highlight the importance of incorporating older critically ill patients in future trials to ensure the results are generalizable to this growing population.

RESUMO

PURPOSE: Patients with hematologic malignancy (HM) commonly develop critical illness. Their long-term survival and functional outcomes have not been well described. METHODS: We conducted a prospective, observational study of HM patients admitted to seven Canadian intensive care units (ICUs) (2018-2020). We followed survivors at 7 days, 6 months and 12 months following ICU discharge. The primary outcome was 12-month survival. We evaluated functional outcomes at 6 and 12 months using the functional independent measure (FIM) and short form (SF)-36 as well as variables associated with 12-month survival. RESULTS: We enrolled 414 patients including 35% women. The median age was 61 (interquartile range, IQR: 52-69), median Sequential Organ Failure Assessment (SOFA) score was 9 (IQR: 6-12), and 22% had moderate-severe frailty (clinical frailty scale [CFS] ≥ 6). 51% had acute leukemia, 38% lymphoma/multiple myeloma, and 40% had received a hematopoietic stem cell transplant (HCT). The most common reasons for ICU admission were acute respiratory failure (50%) and sepsis (40%). Overall, 203 (49%) were alive 7 days post-ICU discharge (ICU survivors). Twelve-month survival of the entire cohort was 21% (43% across ICU survivors). The proportion of survivors with moderate-severe frailty was 42% (at 7 days), 14% (6 months), and 8% (12 months). Median FIM at 7 days was 80 (IQR: 50-109). Physical function, pain, social function, mental health, and emotional well-being were below age- and sex-matched population scores at 6 and 12 months. Frailty, allogeneic HCT, kidney injury, and cardiac complications during ICU were associated with lower 12- month survival. CONCLUSIONS: 49% of all HM patients were alive at 7 days post-ICU discharge, and 21% at 12 months. Survival varied based upon hematologic diagnosis and frailty status. Survivors had important functional disability and impairment in emotional, physical, and general well-being.

RESUMO

Background: Necrotizing pneumonia and lung gangrene represent a continuum of severe lung infection. Traditionally, severe cases have been referred for surgical debridement. However, this has been linked to high mortality. Some groups have published encouraging results using a conservative medical approach. Unfortunately, lack of a standardized definition of necrotizing pneumonia has precluded meaningful comparison between medical and surgical approach in severe cases. Our objective was to describe the outcome of a cohort of severe necrotizing pneumonia treated with optimal medical management. Methods: We conducted an observational retrospective study by reviewing charts and radiology records of patients hospitalized between 2006-2019 in a tertiary center. We included all patients with severe necrotizing infection, defined as a necrotizing cavity involving at least 50% of a lobe, or smaller multilobar cavities. We made no distinction between necrotizing pneumonia and gangrene as there are no standardized criteria. Results: A total of 50 consecutive patients were included. On imaging, 42% had multilobar cavities and mean diameter of the largest cavity in each case was 5.9 cm. 50% required mechanical ventilation (median duration 12 days) and 44% needed vasopressors. Four patients (8%) had decortication surgery, while none underwent lung resection. Four patients (8%) died. The extent of infiltrates and number of cavities were not associated with mortality but the extent of infiltrates was associated with risk of intubation (P=0.004). Conclusions: We presented one of the largest series of medically-treated severe necrotizing lung infections in the pre-coronavirus disease-2019 (COVID-19) era. The overwhelming majority of patients recovered with optimal medical management alone. Our results strongly support avoiding pulmonary resection in patients with severe necrotizing bacterial lung infections.

RESUMO

OBJECTIVES: To evaluate the agreement between three emergency department (ED) vulnerability screeners, including the InterRAI ED Screener, ER2, and PRISMA-7. Our secondary objective was to evaluate the discriminative accuracy of screeners in predicting discharge home and extended ED lengths-of-stay (> 24 h). METHODS: We conducted a nested sub-group study using data from a prospective multi-site cohort study evaluating frailty in older ED patients presenting to four Quebec hospitals. Research nurses assessed patients consecutively with the three screeners. We employed Cohen's Kappa to determine agreement, with high-risk cut-offs of three and four for the PRISMA-7, six for the ER2, and five for the interRAI ED Screener. We used logistic regression to evaluate the discriminative accuracy of instruments, testing them in their dichotomous, full, and adjusted forms (adjusting for age, sex, and hospital academic status). RESULTS: We evaluated 1855 older ED patients across the four hospital sites. The mean age of our sample was 84 years. Agreement between the interRAI ED Screener and the ER2 was fair (K = 0.37; 95% CI 0.33-0.40); agreement between the PRISMA-7 and ER2 was also fair (K = 0.39; 95% CI = 0.36-0.43). Agreement between interRAI ED Screener and PRISMA-7 was poor (K = 0.19; 95% CI 0.16-0.22). Using a cut-off of four for PRISMA-7 improved agreement with the ER2 (K = 0.55; 95% CI 0.51-0.59) and the ED Screener (K = 0.32; 95% CI 0.2-0.36). When predicting discharge home, the concordance statistics among models were similar in their dichotomous (c = 0.57-0.61), full (c = 0.61-0.64), and adjusted forms (c = 0.63-0.65), and poor for all models when predicting extended length-of-stay. CONCLUSION: ED vulnerability scores from the three instruments had a fair agreement and were associated with important patient outcomes. The interRAI ED Screener best identifies older ED patients at greatest risk, while the PRISMA-7 and ER2 are more sensitive instruments.


RéSUMé: OBJECTIFS: Évaluer la concordance entre trois outils de dépistage de la vulnérabilité des urgences, notamment l'InterRAI ED Screener, ER2 et PRISMA-7. Notre objectif secondaire était d'évaluer la précision discriminative des agents de dépistage dans la prédiction de la sortie à domicile et des durées de séjour prolongées à l'urgence (> 24 heures). MéTHODES: Nous avons mené une étude de sous-groupe emboîtée à partir des données d'une étude de cohorte prospective multi-sites évaluant la fragilité chez les patients plus âgés se présentant aux urgences de quatre hôpitaux québécois. Les infirmières de recherche ont évalué les patients consécutivement avec les trois dépisteurs. Nous avons utilisé le Kappa de Cohen pour déterminer la concordance, avec des seuils de risque élevé de trois et quatre pour le PRISMA-7, de six pour l'ER2 et de cinq pour l' interRAI ED Screener. Nous avons utilisé la régression logistique pour évaluer la précision discriminante des instruments, en les testant dans leur forme dichotomique, complète et ajustée (en ajustant pour l'âge, le sexe et le statut académique). RéSULTATS: Nous avons évalué 1 855 patients âgés aux urgences dans les quatre sites hospitaliers. L'âge moyen de notre échantillon était de 84 ans. La concordance entre l'interRAI ED Screener et l'ER2 était équitable (K =0,37 ; IC à 95 % =0,33-0,40) ; la concordance entre le PRISMA-7 et l'ER2 était également équitable (K = 0,39 ; IC à 95 % =0,36-0,43). La concordance entre interRAI ED Screener et PRISMA-7 était faible (K = 0,19 ; IC à 95 % = 0,16-0,22). L'utilisation d'un seuil de quatre pour PRISMA-7 a amélioré la concordance avec l'ER2 (K =0,55 ; IC à 95% =0,51-0,59) et l'ED Screener (K =0,32 ; IC à 95 % =0,2-0,36). En ce qui concerne la prédiction du retour à domicile, les statistiques de concordance entre les modèles étaient similaires dans leurs formes dichotomiques (c = 0,57-0,61), complètes (c =0,61-0,64) et ajustées (c =0,63-0,65), et faibles pour tous les modèles en ce qui concerne la prédiction de la durée de séjour prolongée. CONCLUSION: Les scores de vulnérabilité aux urgences des trois instruments concordaient assez bien et étaient associés à des résultats importants pour les patients.

RESUMO

A growing proportion of critically ill patients admitted in ICUs are older adults. The need for improving care provided to older adults in critical care settings to optimize functional status and quality of life for survivors is acknowledged, but the optimal model of care remains unknown. We aimed to identify and describe reported models of care. DATA SOURCES: We conducted a scoping review on critically ill older adults hospitalized in the ICU. Medline (PubMed), Embase (OvidSP), Cumulative Index to Nursing and Allied Health Literature (Ebsco), and Web of Science (Clarivate) were searched from inception to May 5, 2020. STUDY SELECTION: We included original articles, published abstracts, review articles, editorials, and commentaries describing or discussing the implementation of geriatric-based models of care in critical care, step-down units, and trauma centers. The organization of care had to be described. Articles only discussing geriatric syndromes and specific interventions were not included. DATA EXTRACTION: Full texts of included studies were obtained. We collected publication and study characteristics, structures of care, human resources used, interventions done or proposed, results, and measured outcomes. Data abstraction was done by two investigators and reconciled, and disagreements were resolved by discussion. DATA SYNTHESIS: Our search identified 3,765 articles, and we found 19 reporting on the implementation of geriatric-based models of care in the setting of critical care. Four different models of care were identified: dedicated geriatric beds, geriatric assessment by a geriatrician, geriatric assessment without geriatrician, and a fourth model called "other approaches" including geriatric checklists, bundles of care, and incremental educational strategies. We were unable to assess the superiority of any model due to limited data. CONCLUSIONS: Multiple models have been reported in the literature with varying degrees of resource and labor intensity. More data are required on the impact of these models, their feasibility, and cost-effectiveness.

RESUMO

Background: Renin-angiotensin system inhibitors (RASi) are not re-initiated for almost a quarter of patients who suffered acute kidney injury 6 months after discharge. This discontinuation might be partly explained by the nephrotoxicity of these medications, yet they remain of benefit, especially for patients with heart failure. Objective: To determine the factors deemed by clinicians to influence RASi re-initiation and set threshold values for important safety parameters. Design: Three-round modified online Delphi survey. Setting: The study was conducted in Quebec, Canada. Participants: Twenty clinicians from nephrology, intensive care medicine, and internal medicine. Measurements: The factors' importance was rated on 4-point Likert-type scale, ranging from "not important" to "very important" by the panelists. Methods: We conducted a brief literature review to uncover possible influencing factors followed by a 3-round modified Delphi survey to establish a consensus on the importance of these factors. Results: We recruited 20 clinicians (7 nephrologists, 3 internists, and 10 intensive care physicians). We created a list of 25 factors, 15 of which met consensus. Eleven of these factors, including serum creatinine, glomerular filtration rate, and acute kidney injury (AKI) stage, were deemed as important while 4, such as responsibility ambiguity and absence of feedback, were deemed as not important. The majority of the 10 factors which did not meet consensus were related to the clinical setting, such as a pharmacist follow-up and the required time to ensure optimal RASi re-initiation. Limitations: Quebec clinicians' agreement might not reflect the opinion of the rest of Canada. The survey measures clinicians' belief rather than their actual practice. Conclusion: Renin-angiotensin system inhibitors re-initiation is a rather complex concept which encompasses several factors. Our research uncovered some of these factors which may be used to develop guidelines on optimal RASi re-initiation.


Contexte: Six mois après avoir reçu leur congé de l'hôpital, près du quart des patients ayant vécu un épisode d'insuffisance rénale aiguë n'ont toujours pas réamorcé les inhibiteurs du système rénine-angiotensine (iSRA). Cette interruption pourrait s'expliquer en partie par la néphrotoxicité de ces médicaments, bien qu'ils soient bénéfiques, particulièrement pour les patients souffrant d'insuffisance cardiaque. Objectifs: Déterminer les facteurs jugés par les cliniciens comme exerçant une influence sur la reprise des iSRA et définir des valeurs de seuil pour les paramètres de sécurité considérés comme importants. Conception: Une version modifiée de l'enquête Delphi menée en ligne, en trois étapes. Cadre: Étude menée au Québec (Canada). Participants: 20 cliniciens en néphrologie, en médecine de soins intensifs ou en médecine interne. Mesures: L'importance des facteurs a été évaluée par les panélistes sur une échelle de type Likert à quatre points allant de « pas important ¼ à « très important ¼. Méthodologie: Nous avons procédé à une brève revue de la littérature pour repérer les possibles facteurs influençant la reprise des iSRA. Une enquête Delphi modifiée a ensuite été menée en trois étapes afin d'établir un consensus sur l'importance de ces facteurs. Résultats: Nous avons recruté 20 cliniciens (7 néphrologues, 3 internistes et 10 intensivistes). Nous avons créé une liste de 25 facteurs, dont 15 faisaient consensus. De ceux-ci, 11 ont été jugés importants, notamment la créatinine sérique, le débit de filtration glomérulaire et le stade de l'insuffisance rénale aigüe (IRA); alors que 4, notamment l'ambiguïté de la responsabilité et l'absence de rétroaction, ont été jugés non importants. La majorité des 10 facteurs qui ne faisaient pas consensus étaient liés au milieu clinique, notamment le suivi du pharmacien et le temps nécessaire pour assurer une reprise optimale des iSRA. Limites: L'accord des cliniciens du Québec pourrait ne pas refléter l'opinion des cliniciens du reste du Canada. L'enquête mesure les croyances des cliniciens plutôt que leur pratique réelle. Conclusion: La reprise des iSRA est un concept assez complexe qui englobe plusieurs facteurs. Notre recherche a révélé certains facteurs qui peuvent être utilisés pour élaborer des lignes directrices sur la reprise optimale des iSRA après un épisode d'insuffisance rénale aigüe.
