Outcomes of COVID-19 manuscripts submitted to the Canadian Journal of Anesthesia: a retrospective audit of author gender and person of colour status.

PURPOSE: We aimed to evaluate the representation of women and persons of colour (POC) authors of COVID-19 manuscripts submitted to, accepted in, and rejected from the Journal and to evaluate trends in their representation during the pandemic. METHODS: All COVID-19 manuscripts submitted to the Journal between 1 February 2020 and 30 April 2021 were included. Manuscript data were retrieved from Editorial Manager, and gender and POC status were obtained through: 1) e-mail communication with corresponding authors; 2) e-mail queries to other coauthors; 3) NamSor software, and 4) Internet searches. The data were described using percentages and summary statistics. A two-sample test of proportions was used for comparisons and trends were analyzed with linear regression. RESULTS: We identified 314 manuscripts (1,555 authors), 95 (461 authors) of which were accepted for publication. Of all authors, 515 (33%) were women, and women were the lead and senior authors of 101 (32%) and 69 (23%) manuscripts, respectively. There were no differences in women's representation as authors between accepted and rejected manuscripts. Overall, 923/1,555 (59%) authors were identified as POC, with a significantly lower proportion of POC authors among accepted vs rejected manuscripts (41%, 188/461 vs 67%, 735/1,094; difference, -26%; 95% CI, -32 to -21; P < 0.001). We did not observe significant trends in the proportion of women and POC authors over the study period. CONCLUSION: The proportion of women authors of COVID-19 manuscripts was lower than men's representation. Further research is required to determine the factors that account for the higher proportion of POC authors across rejected manuscripts.

RéSUMé: OBJECTIF: Nous avions pour objectif d'évaluer la représentation des femmes et des personnes de couleur ayant rédigé des manuscrits portant sur la COVID-19 soumis, acceptés et rejetés au Journal et d'évaluer les tendances concernant leur représentation pendant la pandémie. MéTHODE: Tous les manuscrits portant sur la COVID-19 soumis au Journal entre le 1er février 2020 et le 30 avril 2021 ont été inclus. Les données des manuscrits ont été extraites de la plateforme de gestion des manuscrits Editorial Manager, et le sexe et le statut de personne de couleur ont été obtenus par : 1) la communication par courrier électronique avec les auteurs et autrices correspondant·es; 2) des requêtes par courrier électronique envoyées à d'autres coautrices et coauteurs; 3) le logiciel NamSor, et 4) des recherches sur Internet. Les données ont été décrites à l'aide de pourcentages et de statistiques sommaires. Un test de proportions à deux échantillons a été utilisé pour les comparaisons et les tendances ont été analysées par régression linéaire. RéSULTATS: Nous avons identifié 314 manuscrits (1555 auteurs et autrices), dont 95 (461 autrices et auteurs) ont été acceptés pour publication. Parmi tou·tes les auteurs/autrices, 515 (33 %) étaient des femmes, et les femmes étaient les autrices principales et senior de 101 (32 %) et 69 (23 %) manuscrits, respectivement. Il n'y avait aucune différence dans la représentation des femmes en tant qu'autrices entre les manuscrits acceptés et rejetés. Dans l'ensemble, 923/1555 (59 %) auteurs et autrices ont été identifié·es comme étant des personnes de couleur, avec une proportion significativement plus faible d'autrices et d'auteurs de couleur parmi les manuscrits acceptés vs rejetés (41 %, 188/461 vs 67 %, 735/1094; différence, -26 %; IC 95 %, -32 à -21; P < 0,001). Nous n'avons pas observé de tendances significatives dans la proportion d'auteurs et d'autrices femmes et de couleur au cours de la période à l'étude. CONCLUSION: La proportion de femmes autrices de manuscrits sur la COVID-19 était inférieure à celle des hommes. D'autres recherches sont nécessaires pour déterminer les facteurs qui expliquent la plus grande proportion d'autrices et d'auteurs de couleur parmi les manuscrits rejetés.

A qualitative descriptive study of the impact of the COVID-19 pandemic on staff in a Canadian intensive care unit.

PURPOSE: We sought to explore the lived experiences of a professionally diverse sample of healthcare workers (HCWs) in a single intensive care unit (ICU) serving a large and generalizable Canadian population. We aimed to understand how working during the COVID-19 pandemic affected their professional and personal lives, including their perceptions of institutional support, to inform interventions to ameliorate impacts of the COVID-19 and future pandemics. METHODS: In this qualitative descriptive study, 23 ICU HCWs, identified using convenience purposive sampling, took part in individual semistructured interviews between July and November 2020, shortly after the first wave of the pandemic in Ontario. We used inductive thematic analysis to identify major themes. RESULTS: We identified five major themes related to the COVID-19 pandemic: 1) communication and informational needs (e.g., challenges communicating policy changes); 2) adjusting to restricted visitation (e.g., spending less time interacting with patients); 3) staffing and workplace supports (e.g., importance of positive team dynamics); 4) permeability of professional and personal lives (e.g., balancing shift work and childcare); and 5) a dynamic COVID-19 landscape (e.g., coping with constant change). The COVID-19 pandemic contributed to HCWs in the ICU experiencing varied negative repercussions on their work environment, including staffing and institutional support, which carried into their personal lives. CONCLUSION: Healthcare workers in the ICU perceived that the COVID-19 pandemic had negative repercussions on their work environment, including staffing and institutional support, as well as their professional and personal lives. Understanding both the negative and positive experiences of all ICU HCWs working during the COVID-19 pandemic is critical to future pandemic preparedness. Their perspectives will help to inform the development of mental health and wellbeing interventions to support staff during the COVID-19 pandemic and beyond.

RéSUMé: OBJECTIF: Nous avons cherché à explorer les expériences vécues par un échantillon varié de travailleurs de la santé (TS) dans une seule unité de soins intensifs (USI) desservant une population canadienne vaste et généralisable. Notre objectif était de comprendre comment le travail pendant la pandémie de COVID-19 a affecté leur vie professionnelle et personnelle, y compris leurs perceptions du soutien institutionnel, afin d'éclairer les interventions visant à atténuer les impacts de la COVID-19 et des pandémies futures. MéTHODE: Dans cette étude qualitative descriptive, 23 travailleurs de la santé en soins intensifs, identifiés à l'aide d'un échantillonnage raisonné de commodité, ont participé à des entrevues individuelles semi-structurées entre juillet et novembre 2020, peu après la première vague de la pandémie en Ontario. Nous avons utilisé l'analyse thématique inductive pour identifier les principaux thèmes. RéSULTATS: Nous avons cerné cinq grands thèmes liés à la pandémie de COVID-19 : 1) les besoins en matière de communication et d'information (p. ex., les difficultés à communiquer les changements de politiques); 2) l'adaptation aux visites restreintes (p. ex., le fait de passer moins de temps à interagir avec les patients); 3) le soutien à la dotation en personnel et au milieu de travail (p. ex., l'importance d'une dynamique d'équipe positive); 4) la perméabilité de la vie professionnelle et personnelle (p. ex., l'équilibre entre le travail en quarts et la garde des enfants); et 5) le paysage dynamique de la COVID-19 (p. ex., l'adaptation à des changements constants). La pandémie de COVID-19 a contribué à ce que les travailleurs de la santé de l'USI subissent divers impacts négatifs sur leur environnement de travail, y compris sur la dotation en personnel et le soutien institutionnel, qui se sont répercutés sur leur vie personnelle. CONCLUSION: Les travailleurs de la santé de l'USI ont perçu que la pandémie de COVID-19 avait eu des répercussions négatives sur leur environnement de travail, y compris sur la dotation en personnel et le soutien institutionnel, ainsi que sur leur vie professionnelle et personnelle. Il est essentiel de comprendre les expériences négatives et positives de tous les travailleurs de la santé des soins intensifs travaillant pendant la pandémie de COVID-19 pour bien se préparer aux pandémies futures. Leurs points de vue aideront à l'élaboration d'interventions en santé mentale et en bien-être pour soutenir le personnel pendant la pandémie de COVID-19 et au-delà.

Wellness and Coping of Physicians Who Worked in ICUs During the Pandemic: A Multicenter Cross-Sectional North American Survey.

OBJECTIVES: Few surveys have focused on physician moral distress, burnout, and professional fulfilment. We assessed physician wellness and coping during the COVID-19 pandemic. DESIGN: Cross-sectional survey using four validated instruments. SETTING: Sixty-two sites in Canada and the United States. SUBJECTS: Attending physicians (adult, pediatric; intensivist, nonintensivist) who worked in North American ICUs. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: We analysed 431 questionnaires (43.3% response rate) from 25 states and eight provinces. Respondents were predominantly male (229 [55.6%]) and in practice for 11.8 ± 9.8 years. Compared with prepandemic, respondents reported significant intrapandemic increases in days worked/mo, ICU bed occupancy, and self-reported moral distress (240 [56.9%]) and burnout (259 [63.8%]). Of the 10 top-ranked items that incited moral distress, most pertained to regulatory/organizational ( n = 6) or local/institutional ( n = 2) issues or both ( n = 2). Average moral distress (95.6 ± 66.9), professional fulfilment (6.5 ± 2.1), and burnout scores (3.6 ± 2.0) were moderate with 227 physicians (54.6%) meeting burnout criteria. A significant dose-response existed between COVID-19 patient volume and moral distress scores. Physicians who worked more days/mo and more scheduled in-house nightshifts, especially combined with more unscheduled in-house nightshifts, experienced significantly more moral distress. One in five physicians used at least one maladaptive coping strategy. We identified four coping profiles (active/social, avoidant, mixed/ambivalent, infrequent) that were associated with significant differences across all wellness measures. CONCLUSIONS: Despite moderate intrapandemic moral distress and burnout, physicians experienced moderate professional fulfilment. However, one in five physicians used at least one maladaptive coping strategy. We highlight potentially modifiable factors at individual, institutional, and regulatory levels to enhance physician wellness.

Intravenous Vitamin C in Adults with Sepsis in the Intensive Care Unit.

BACKGROUND: Studies that have evaluated the use of intravenous vitamin C in adults with sepsis who were receiving vasopressor therapy in the intensive care unit (ICU) have shown mixed results with respect to the risk of death and organ dysfunction. METHODS: In this randomized, placebo-controlled trial, we assigned adults who had been in the ICU for no longer than 24 hours, who had proven or suspected infection as the main diagnosis, and who were receiving a vasopressor to receive an infusion of either vitamin C (at a dose of 50 mg per kilogram of body weight) or matched placebo administered every 6 hours for up to 96 hours. The primary outcome was a composite of death or persistent organ dysfunction (defined by the use of vasopressors, invasive mechanical ventilation, or new renal-replacement therapy) on day 28. RESULTS: A total of 872 patients underwent randomization (435 to the vitamin C group and 437 to the control group). The primary outcome occurred in 191 of 429 patients (44.5%) in the vitamin C group and in 167 of 434 patients (38.5%) in the control group (risk ratio, 1.21; 95% confidence interval [CI], 1.04 to 1.40; P = 0.01). At 28 days, death had occurred in 152 of 429 patients (35.4%) in the vitamin C group and in 137 of 434 patients (31.6%) in the placebo group (risk ratio, 1.17; 95% CI, 0.98 to 1.40) and persistent organ dysfunction in 39 of 429 patients (9.1%) and 30 of 434 patients (6.9%), respectively (risk ratio, 1.30; 95% CI, 0.83 to 2.05). Findings were similar in the two groups regarding organ-dysfunction scores, biomarkers, 6-month survival, health-related quality of life, stage 3 acute kidney injury, and hypoglycemic episodes. In the vitamin C group, one patient had a severe hypoglycemic episode and another had a serious anaphylaxis event. CONCLUSIONS: In adults with sepsis receiving vasopressor therapy in the ICU, those who received intravenous vitamin C had a higher risk of death or persistent organ dysfunction at 28 days than those who received placebo.

Lessening Organ Dysfunction With Vitamin C (LOVIT) Trial: Statistical Analysis Plan.

BACKGROUND: The LOVIT (Lessening Organ Dysfunction with Vitamin C) trial is a blinded multicenter randomized clinical trial comparing high-dose intravenous vitamin C to placebo in patients admitted to the intensive care unit with proven or suspected infection as the main diagnosis and receiving a vasopressor. OBJECTIVE: We aim to describe a prespecified statistical analysis plan (SAP) for the LOVIT trial prior to unblinding and locking of the trial database. METHODS: The SAP was designed by the LOVIT principal investigators and statisticians, and approved by the steering committee and coinvestigators. The SAP defines the primary and secondary outcomes, and describes the planned primary, secondary, and subgroup analyses. RESULTS: The SAP includes a draft participant flow diagram, tables, and planned figures. The primary outcome is a composite of mortality and persistent organ dysfunction (receipt of mechanical ventilation, vasopressors, or new renal replacement therapy) at 28 days, where day 1 is the day of randomization. All analyses will use a frequentist statistical framework. The analysis of the primary outcome will estimate the risk ratio and 95% CI in a generalized linear mixed model with binomial distribution and log link, with site as a random effect. We will perform a secondary analysis adjusting for prespecified baseline clinical variables. Subgroup analyses will include age, sex, frailty, severity of illness, Sepsis-3 definition of septic shock, baseline ascorbic acid level, and COVID-19 status. CONCLUSIONS: We have developed an SAP for the LOVIT trial and will adhere to it in the analysis phase. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/36261.

The impact of the COVID-19 pandemic on intensive care unit workers: a nationwide survey.

PURPOSE: To evaluate the impact of the COVID-19 pandemic on Canadian intensive care unit (ICU) workers. METHODS: Between June and August 2020, we distributed a cross-sectional online survey of ICU workers evaluating the impact of the pandemic, coping strategies, symptoms of post-traumatic stress disorder (PTSD; Impact of Events Scale-Revised), and psychological distress, anxiety, and depression (Kessler Psychological Distress Scale). We performed regression analyses to determine the predictors of psychological symptoms. RESULTS: We analyzed responses from 455 ICU workers (80% women; 67% from Ontario; 279 nurses, 69 physicians, and 107 other healthcare professionals). Respondents felt that their job put them at great risk of exposure (60%), were concerned about transmitting COVID-19 to family members (76%), felt more stressed at work (67%), and considered leaving their job (37%). Overall, 25% had probable PTSD and 18% had minimal or greater psychological distress. Nurses were more likely to report PTSD symptoms (33%) and psychological distress (23%) than physicians (5% for both) and other health disciplines professionals (19% and 14%). Variables associated with PTSD and psychological distress included female sex (beta-coefficient [B], 1.59; 95% confidence interval [CI], 1.20 to 2.10 and B, 3.79; 95% CI, 1.79 to 5.78, respectively; P < 0.001 for differences in scores across groups) and perceived increased risk due to PPE shortage or inadequate PPE training (B, 1.87; 95% CI, 1.51 to 2.31 and B, 4.88; 95% CI, 3.34 to 6.43, respectively). Coping strategies included talking to friends/family/colleagues (80%), learning about COVID-19 (78%), and physical exercise (68%). Over half endorsed the following workplace strategies as valuable: hospital-provided scrubs, clear communication and protocols by hospitals, knowing their voice is heard, subsidized parking, and gestures of appreciation from leadership. CONCLUSIONS: This survey study shows that ICU workers have been impacted by the COVID-19 pandemic with high levels of stress and psychological burden. Respondents endorsed communication, protocols, and appreciation from leadership as helpful mitigating strategies.

RéSUMé: OBJECTIF: Évaluer l'impact de la pandémie de COVID-19 sur les travailleurs canadiens des unités de soins intensifs (USI). MéTHODE: Entre juin et août 2020, nous avons fait parvenir un sondage transversal en ligne aux travailleurs des soins intensifs pour évaluer l'impact de la pandémie, les stratégies d'adaptation et les symptômes de stress post-traumatique (SPT; Échelle révisée de l'impact de l'événement - IES-R), ainsi que la détresse psychologique, l'anxiété et la dépression (Échelle de détresse psychologique de Kessler). Nous avons réalisé des analyses de régression pour déterminer les prédicteurs de symptômes psychologiques. RéSULTATS: Nous avons analysé les réponses de 455 travailleurs des soins intensifs (80 % de femmes; 67 % de l'Ontario; 279 infirmières/infirmiers, 69 médecins et 107 autres professionnels de la santé). Les répondants ont estimé que leur emploi les plaçait face à un risque élevé d'exposition (60 %), craignaient de transmettre la COVID-19 aux membres de leur famille (76 %), se sentaient plus stressés au travail (67 %) et avaient envisagé de quitter leur emploi (37 %). Dans l'ensemble, 25 % souffraient probablement d'un SPT et 18 % présentaient une détresse psychologique minimale ou supérieure. Les infirmières et infirmiers étaient plus susceptibles de rapporter des symptômes de SPT (33 %) et de détresse psychologique (23 %) que les médecins (5 % pour les deux) et les professionnels de la santé des autres disciplines (19 % et 14 %). Les variables associées à un SPT et à la détresse psychologique comprenaient le sexe féminin (coefficient bêta [B], 1,59; intervalle de confiance [IC] à 95 %, 1,20 à 2,10 et B, 3,79; IC 95 %, 1,79 à 5,78, respectivement; P < 0,001 pour les différences de scores entre les groupes) et la perception d'un risque accru en raison des pénuries d'EPI ou d'une formation inadéquate en EPI (B, 1,87; IC 95 %, 1,51 à 2,31 et B, 4,88; IC 95 %, 3,34 à 6,43, respectivement). Les stratégies d'adaptation comprenaient le fait de parler aux amis, à la famille ou aux collègues (80 %), l'acquisition de connaissances concernant la COVID-19 (78 %) et l'exercice physique (68 %). Plus de la moitié ont estimé que les stratégies de travail suivantes étaient utiles : des uniformes fournis par les hôpitaux, une communication et des protocoles clairs de la part des hôpitaux, le fait de savoir que leur voix est entendue, un stationnement subventionné et des gestes d'appréciation de la part des dirigeants. CONCLUSION: Cette étude montre que les travailleurs des soins intensifs ont été touchés par la pandémie de COVID-19 avec des niveaux élevés de stress et de fardeau psychologique. Les répondants ont déclaré que la communication, les protocoles et les gestes d'appréciation de la direction constituaient des stratégies d'atténuation utiles.

Development of a repeated-measures predictive model and clinical risk score for mortality in ventilated COVID-19 patients.

PURPOSE: The COVID-19 pandemic has caused intensive care units (ICUs) to reach capacities requiring triage. A tool to predict mortality risk in ventilated patients with COVID-19 could inform decision-making and resource allocation, and allow population-level comparisons across institutions. METHODS: This retrospective cohort study included all mechanically ventilated adults with COVID-19 admitted to three tertiary care ICUs in Toronto, Ontario, between 1 March 2020 and 15 December 2020. Generalized estimating equations were used to identify variables predictive of mortality. The primary outcome was the probability of death at three-day intervals from the time of ICU admission (day 0), with risk re-calculation every three days to day 15; the final risk calculation estimated the probability of death at day 15 and beyond. A numerical algorithm was developed from the final model coefficients. RESULTS: One hundred twenty-seven patients were eligible for inclusion. Median ICU length of stay was 26.9 (interquartile range, 15.4-52.0) days. Overall mortality was 42%. From day 0 to 15, the variables age, temperature, lactate level, ventilation tidal volume, and vasopressor use significantly predicted mortality. Our final clinical risk score had an area under the receiver-operating characteristics curve of 0.9 (95% confidence interval [CI], 0.8 to 0.9). For every ten-point increase in risk score, the relative increase in the odds of death was approximately 4, with an odds ratio of 4.1 (95% CI, 2.9 to 5.9). CONCLUSION: Our dynamic prediction tool for mortality in ventilated patients with COVID-19 has excellent diagnostic properties. Notwithstanding, external validation is required before widespread implementation.

RéSUMé: OBJECTIF: En raison de la pandémie de COVID-19, les unités de soins intensifs (USI) ont atteint des taux d'occupation nécessitant un triage. Un outil pour prédire le risque de mortalité chez les patients sous ventilation atteints de COVID-19 pourrait éclairer la prise de décision et l'attribution des ressources tout en permettant des comparaisons populationnelles entre les établissements. MéTHODE: Cette étude de cohorte rétrospective a inclus tous les adultes atteints de COVID-19 sous ventilation mécanique admis dans trois USI de centres de soins tertiaires à Toronto, en Ontario, entre le 1er mars 2020 et le 15 décembre 2020. Des équations d'estimation généralisées ont été utilisées pour identifier les variables prédictives de mortalité. Le critère d'évaluation principal était la probabilité de décès à des intervalles de trois jours à partir du moment de l'admission à l'USI (jour 0), avec un nouveau calcul du risque tous les trois jours jusqu'au jour 15; le calcul final du risque a estimé la probabilité de décès au jour 15 et au-delà. Un algorithme numérique a été mis au point à partir des coefficients du modèle final. RéSULTATS: Cent vingt-sept patients étaient éligibles à l'inclusion. La durée médiane de séjour à l'USI était de 26,9 jours (écart interquartile, 15,4 à 52,0). La mortalité globale était de 42 %. Du jour 0 au jour 15, les variables que sont l'âge, la température, les taux de lactate, le volume courant de ventilation et l'utilisation de vasopresseurs ont constitué des prédicteurs significatifs de mortalité. Notre score de risque clinique final avait une aire sous la courbe ROC de 0,9 (intervalle de confiance [IC] à 95 %, 0,8 à 0,9). Pour chaque augmentation de dix points du score de risque, l'augmentation relative des risques de décès était d'environ 4, avec un rapport de cotes de 4,1 (IC 95 %, 2,9 à 5,9). CONCLUSION: Notre outil de prédiction dynamique de la mortalité pour les patients ventilés atteints de COVID-19 possède d'excellentes propriétés diagnostiques. Néanmoins, une validation externe est nécessaire avant sa mise en œuvre généralisée.

Personal, professional, and psychological impact of the COVID-19 pandemic on hospital workers: A cross-sectional survey.

OBJECTIVES: We aimed to evaluate the personal, professional, and psychological impact of the COVID-19 pandemic on hospital workers and their perceptions about mitigating strategies. DESIGN: Cross-sectional web-based survey consisting of (1) a survey of the personal and professional impact of the COVID-19 pandemic and potential mitigation strategies, and (2) two validated psychological instruments (Kessler Psychological Distress Scale [K10] and Impact of Events Scale Revised [IES-R]). Regression analyses were conducted to identify the predictors of workplace stress, psychological distress, and post-traumatic stress. SETTING AND PARTICIPANTS: Hospital workers employed at 4 teaching and 8 non-teaching hospitals in Ontario, Canada during the COVID-19 pandemic. RESULTS: Among 1875 respondents (84% female, 49% frontline workers), 72% feared falling ill, 64% felt their job placed them at great risk of COVID-19 exposure, and 48% felt little control over the risk of infection. Respondents perceived that others avoided them (61%), reported increased workplace stress (80%), workload (66%) and responsibilities (59%), and 44% considered leaving their job. The psychological questionnaires revealed that 25% had at least some psychological distress on the K10, 50% had IES-R scores suggesting clinical concern for post-traumatic stress, and 38% fulfilled criteria for at least one psychological diagnosis. Female gender and feeling at increased risk due to PPE predicted all adverse psychological outcomes. Respondents favoured clear hospital communication (59%), knowing their voice is heard (55%), expressions of appreciation from leadership (55%), having COVID-19 protocols (52%), and food and beverages provided by the hospital (50%). CONCLUSIONS: Hospital work during the COVID-19 pandemic has had important personal, professional, and psychological impacts. Respondents identified opportunities to better address information, training, and support needs.

Perspectives of patients, family members, health professionals and the public on the impact of COVID-19 on mental health.

BACKGROUND: The coronavirus (COVID-19) pandemic has seen a global surge in anxiety, depression, post-traumatic stress disorder (PTSD), and stress. AIMS: This study aimed to describe the perspectives of patients with COVID-19, their family, health professionals, and the general public on the impact of COVID-19 on mental health. METHODS: A secondary thematic analysis was conducted using data from the COVID-19 COS project. We extracted data on the perceived causes and impact of COVID-19 on mental health from an international survey and seven online consensus workshops. RESULTS: We identified four themes (with subthemes in parenthesis): anxiety amidst uncertainty (always on high alert, ebb and flow of recovery); anguish of a threatened future (intense frustration of a changed normality, facing loss of livelihood, trauma of ventilation, a troubling prognosis, confronting death); bearing responsibility for transmission (fear of spreading COVID-19 in public; overwhelming guilt of infecting a loved one); and suffering in isolation (severe solitude of quarantine, sick and alone, separation exacerbating grief). CONCLUSION: We found that the unpredictability of COVID-19, the fear of long-term health consequences, burden of guilt, and suffering in isolation profoundly impacted mental health. Clinical and public health interventions are needed to manage the psychological consequences arising from this pandemic.

Optimizing Sedation in Patients Receiving Mechanical Ventilation

Analgesia and sedation management are key elements of care for patients receiving mechanical ventilation. The excessive use of sedatives can lead to serious short- and long-term complications;conversely the inadequate management of pain and agitation can further complicate patients’ course of illness. Delirium is highly prevalent in critically ill patients, frequently underrecognized, and associated with adverse outcomes. Early mobilization can help reduce sedation use and may improve delirium management. In this chapter we address ideal sedation management in critically ill patients, and how it can positively impact patients wellbeing.

VTE Prophylaxis in Critically Ill Adults: A Systematic Review and Network Meta-analysis.

BACKGROUND: Critically ill adults are at increased risk of VTE, including DVT, and pulmonary embolism. Various agents exist for venous thromboprophylaxis in this population. RESEARCH QUESTION: What is the comparative efficacy and safety of prophylaxis agents for prevention of VTE in critically ill adults? STUDY DESIGN AND METHODS: Systematic review and network meta-analysis of randomized clinical trials (RCTs) evaluating efficacy of thromboprophylaxis agents among critically ill patients. We searched six databases (including PubMed, EMBASE, and Medline) from inception through January 2021 for RCTs of patients in the ICU receiving pharmacologic, mechanical, or combination therapy (pharmacologic agents and mechanical devices) for thromboprophylaxis. Two reviewers performed screening, full-text review, and extraction. We used the Grading of Recommendations Assessment, Development, and Evaluation to rate certainty of effect estimates. RESULTS: We included 13 RCTs (9,619 patients). Compared with control treatment (a composite of no prophylaxis, placebo, or compression stockings only), low-molecular-weight heparin (LMWH) reduced the incidence of DVT (OR, 0.59 [95% credible interval [CrI], 0.33-0.90]; high certainty) and unfractionated heparin (UFH) may reduce the incidence of DVT (OR, 0.82 [95% CrI, 0.47-1.37]; low certainty). LMWH probably reduces DVT compared with UFH (OR, 0.72 [95% CrI, 0.46-0.98]; moderate certainty). Compressive devices may reduce risk of DVT compared with control treatments; however, this is based on low-certainty evidence (OR, 0.85 [95% CrI, 0.50-1.50]). Combination therapy showed unclear effect on DVT compared with either therapy alone (very low certainty). INTERPRETATION: Among critically ill adults, compared with control treatment, LMWH reduces incidence of DVT, whereas UFH and mechanical compressive devices may reduce the risk of DVT. LMWH is probably more effective than UFH in reducing incidence of DVT and should be considered the primary pharmacologic agent for thromboprophylaxis. The efficacy and safety of combination pharmacologic therapy and mechanical compressive devices were unclear. TRIAL REGISTRY: Open Science Framework; URL: https://osf.io/694aj.

Expert consensus statements for the management of COVID-19-related acute respiratory failure using a Delphi method.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic has caused unprecedented pressure on healthcare system globally. Lack of high-quality evidence on the respiratory management of COVID-19-related acute respiratory failure (C-ARF) has resulted in wide variation in clinical practice. METHODS: Using a Delphi process, an international panel of 39 experts developed clinical practice statements on the respiratory management of C-ARF in areas where evidence is absent or limited. Agreement was defined as achieved when > 70% experts voted for a given option on the Likert scale statement or > 80% voted for a particular option in multiple-choice questions. Stability was assessed between the two concluding rounds for each statement, using the non-parametric Chi-square (χ2) test (p < 0·05 was considered as unstable). RESULTS: Agreement was achieved for 27 (73%) management strategies which were then used to develop expert clinical practice statements. Experts agreed that COVID-19-related acute respiratory distress syndrome (ARDS) is clinically similar to other forms of ARDS. The Delphi process yielded strong suggestions for use of systemic corticosteroids for critical COVID-19; awake self-proning to improve oxygenation and high flow nasal oxygen to potentially reduce tracheal intubation; non-invasive ventilation for patients with mixed hypoxemic-hypercapnic respiratory failure; tracheal intubation for poor mentation, hemodynamic instability or severe hypoxemia; closed suction systems; lung protective ventilation; prone ventilation (for 16-24 h per day) to improve oxygenation; neuromuscular blocking agents for patient-ventilator dyssynchrony; avoiding delay in extubation for the risk of reintubation; and similar timing of tracheostomy as in non-COVID-19 patients. There was no agreement on positive end expiratory pressure titration or the choice of personal protective equipment. CONCLUSION: Using a Delphi method, an agreement among experts was reached for 27 statements from which 20 expert clinical practice statements were derived on the respiratory management of C-ARF, addressing important decisions for patient management in areas where evidence is either absent or limited. TRIAL REGISTRATION: The study was registered with Clinical trials.gov Identifier: NCT04534569.

Core Outcome Measures for Trials in People With Coronavirus Disease 2019: Respiratory Failure, Multiorgan Failure, Shortness of Breath, and Recovery.

OBJECTIVES: Respiratory failure, multiple organ failure, shortness of breath, recovery, and mortality have been identified as critically important core outcomes by more than 9300 patients, health professionals, and the public from 111 countries in the global coronavirus disease 2019 core outcome set initiative. The aim of this project was to establish the core outcome measures for these domains for trials in coronavirus disease 2019. DESIGN: Three online consensus workshops were convened to establish outcome measures for the four core domains of respiratory failure, multiple organ failure, shortness of breath, and recovery. SETTING: International. PATIENTS: About 130 participants (patients, public, and health professionals) from 17 countries attended the three workshops. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Respiratory failure, assessed by the need for respiratory support based on the World Health Organization Clinical Progression Scale, was considered pragmatic, objective, and with broad applicability to various clinical scenarios. The Sequential Organ Failure Assessment was recommended for multiple organ failure, because it was routinely used in trials and clinical care, well validated, and feasible. The Modified Medical Research Council measure for shortness of breath, with minor adaptations (recall period of 24 hr to capture daily fluctuations and inclusion of activities to ensure relevance and to capture the extreme severity of shortness of breath in people with coronavirus disease 2019), was regarded as fit for purpose for this indication. The recovery measure was developed de novo and defined as the absence of symptoms, resumption of usual daily activities, and return to the previous state of health prior to the illness, using a 5-point Likert scale, and was endorsed. CONCLUSIONS: The coronavirus disease 2019 core outcome set recommended core outcome measures have content validity and are considered the most feasible and acceptable among existing measures. Implementation of the core outcome measures in trials in coronavirus disease 2019 will ensure consistency and relevance of the evidence to inform decision-making and care of patients with coronavirus disease 2019.

Analgesia and sedation in patients with ARDS.

Acute Respiratory Distress Syndrome (ARDS) is one of the most demanding conditions in an Intensive Care Unit (ICU). Management of analgesia and sedation in ARDS is particularly challenging. An expert panel was convened to produce a "state-of-the-art" article to support clinicians in the optimal management of analgesia/sedation in mechanically ventilated adults with ARDS, including those with COVID-19. Current ICU analgesia/sedation guidelines promote analgesia first and minimization of sedation, wakefulness, delirium prevention and early rehabilitation to facilitate ventilator and ICU liberation. However, these strategies cannot always be applied to patients with ARDS who sometimes require deep sedation and/or paralysis. Patients with severe ARDS may be under-represented in analgesia/sedation studies and currently recommended strategies may not be feasible. With lightened sedation, distress-related symptoms (e.g., pain and discomfort, anxiety, dyspnea) and patient-ventilator asynchrony should be systematically assessed and managed through interprofessional collaboration, prioritizing analgesia and anxiolysis. Adaptation of ventilator settings (e.g., use of a pressure-set mode, spontaneous breathing, sensitive inspiratory trigger) should be systematically considered before additional medications are administered. Managing the mechanical ventilator is of paramount importance to avoid the unnecessary use of deep sedation and/or paralysis. Therefore, applying an "ABCDEF-R" bundle (R = Respiratory-drive-control) may be beneficial in ARDS patients. Further studies are needed, especially regarding the use and long-term effects of fast-offset drugs (e.g., remifentanil, volatile anesthetics) and the electrophysiological assessment of analgesia/sedation (e.g., electroencephalogram devices, heart-rate variability, and video pupillometry). This review is particularly relevant during the COVID-19 pandemic given drug shortages and limited ICU-bed capacity.

Core Outcomes Set for Trials in People With Coronavirus Disease 2019.

OBJECTIVES: The outcomes reported in trials in coronavirus disease 2019 are extremely heterogeneous and of uncertain patient relevance, limiting their applicability for clinical decision-making. The aim of this workshop was to establish a core outcomes set for trials in people with suspected or confirmed coronavirus disease 2019. DESIGN: Four international online multistakeholder consensus workshops were convened to discuss proposed core outcomes for trials in people with suspected or confirmed coronavirus disease 2019, informed by a survey involving 9,289 respondents from 111 countries. The transcripts were analyzed thematically. The workshop recommendations were used to finalize the core outcomes set. SETTING: International. SUBJECTS: Adults 18 years old and over with confirmed or suspected coronavirus disease 2019, their family members, members of the general public and health professionals (including clinicians, policy makers, regulators, funders, researchers). INTERVENTIONS: None. MEASUREMENTS: None. MAIN RESULTS: Six themes were identified. "Responding to the critical and acute health crisis" reflected the immediate focus on saving lives and preventing life-threatening complications that underpinned the high prioritization of mortality, respiratory failure, and multiple organ failure. "Capturing different settings of care" highlighted the need to minimize the burden on hospitals and to acknowledge outcomes in community settings. "Encompassing the full trajectory and severity of disease" was addressing longer term impacts and the full spectrum of illness (e.g. shortness of breath and recovery). "Distinguishing overlap, correlation and collinearity" meant recognizing that symptoms such as shortness of breath had distinct value and minimizing overlap (e.g. lung function and pneumonia were on the continuum toward respiratory failure). "Recognizing adverse events" refers to the potential harms of new and evolving interventions. "Being cognizant of family and psychosocial wellbeing" reflected the pervasive impacts of coronavirus disease 2019. CONCLUSIONS: Mortality, respiratory failure, multiple organ failure, shortness of breath, and recovery are critically important outcomes to be consistently reported in coronavirus disease 2019 trials.

International Survey to Establish Prioritized Outcomes for Trials in People With Coronavirus Disease 2019.

OBJECTIVES: There are over 4,000 trials conducted in people with coronavirus disease 2019. However, the variability of outcomes and the omission of patient-centered outcomes may diminish the impact of these trials on decision-making. The aim of this study was to generate a consensus-based, prioritized list of outcomes for coronavirus disease 2019 trials. DESIGN: In an online survey conducted in English, Chinese, Italian, Portuguese, and Spanish languages, adults with coronavirus disease 2019, their family members, health professionals, and the general public rated the importance of outcomes using a 9-point Likert scale (7-9, critical importance) and completed a Best-Worst Scale to estimate relative importance. Participant comments were analyzed thematically. SETTING: International. SUBJECTS: Adults 18 years old and over with confirmed or suspected coronavirus disease 2019, their family members, members of the general public, and health professionals (including clinicians, policy makers, regulators, funders, and researchers). INTERVENTIONS: None. MEASUREMENTS: None. MAIN RESULTS: In total, 9,289 participants from 111 countries (776 people with coronavirus disease 2019 or family members, 4,882 health professionals, and 3,631 members of the public) completed the survey. The four outcomes of highest priority for all three groups were: mortality, respiratory failure, pneumonia, and organ failure. Lung function, lung scarring, sepsis, shortness of breath, and oxygen level in the blood were common to the top 10 outcomes across all three groups (mean > 7.5, median ≥ 8, and > 70% of respondents rated the outcome as critically important). Patients/family members rated fatigue, anxiety, chest pain, muscle pain, gastrointestinal problems, and cardiovascular disease higher than health professionals. Four themes underpinned prioritization: fear of life-threatening, debilitating, and permanent consequences; addressing knowledge gaps; enabling preparedness and planning; and tolerable or infrequent outcomes. CONCLUSIONS: Life-threatening respiratory and other organ outcomes were consistently highly prioritized by all stakeholder groups. Patients/family members gave higher priority to many patient-reported outcomes compared with health professionals.
