RESUMO
BACKGROUND: We aimed to synthesize the qualitative evidence on the impacts of COVID-19-related restricted family presence policies from the perspective of patients, families, and healthcare professionals from neonatal (NICU), pediatric (PICU), or adult ICUs. METHODS: We searched MEDLINE, EMBASE, Cochrane Databases of Reviews and Clinical Trials, CINAHL, Scopus, PsycINFO, and Web of Science. Two researchers independently reviewed titles/abstracts and full-text articles for inclusion. Thematic analysis was completed following appraising article quality and assessing confidence in the individual review findings using standardized tools. RESULTS: We synthesized 54 findings from 184 studies, revealing the impacts of these policies in children and adults on: (1) Family integrated care and patient and family-centered care (e.g., disruption to breastfeeding/kangaroo care, dehumanizing of patients); (2) Patients, families, and healthcare professionals (e.g., negative mental health consequences, moral distress); (3) Support systems (e.g., loss of support from friends/families); and (4) Relationships (e.g., loss of essential bonding with infant, struggle to develop trust). Strategies to mitigate these impacts are reported. CONCLUSION: This review highlights the multifaceted impacts of restricted visitation policies across distinct care settings and strategies to mitigate the harmful effects of these policies and guide the creation of compassionate family presence policies in future health crises.

This rapid practice guideline provides evidence-based recommendations for the use of awake proning in adult patients with acute hypoxemic respiratory failure due to COVID-19. The panel included 20 experts from 12 countries, including one patient representative, and used a strict conflict of interest policy for potential financial and intellectual conflicts of interest. Methodological support was provided by the guidelines in intensive care, development, and evaluation (GUIDE) group. Based on an updated systematic review, and the grading of recommendations, assessment, development, and evaluation (GRADE) method we evaluated the certainty of evidence and developed recommendations using the Evidence-to-Decision framework. We conducted an electronic vote, requiring >80% agreement amongst the panel for a recommendation to be adopted. The panel made a strong recommendation for a trial of awake proning in adult patients with COVID-19 related hypoxemic acute respiratory failure who are not invasively ventilated. Awake proning appears to reduce the risk of tracheal intubation, although it may not reduce mortality. The panel judged that most patients would want a trial of awake proning, although this may not be feasible in some patients and some patients may not tolerate it. However, given the high risk of clinical deterioration amongst these patients, awake proning should be conducted in an area where patients can be monitored by staff experienced in rapidly detecting and managing clinical deterioration. This RPG panel recommends a trial of awake prone positioning in patients with acute hypoxemic respiratory failure due to COVID-19.

Importance: The efficacy and safety of prone positioning is unclear in nonintubated patients with acute hypoxemia and COVID-19. Objective: To evaluate the efficacy and adverse events of prone positioning in nonintubated adult patients with acute hypoxemia and COVID-19. Design, Setting, and Participants: Pragmatic, unblinded randomized clinical trial conducted at 21 hospitals in Canada, Kuwait, Saudi Arabia, and the US. Eligible adult patients with COVID-19 were not intubated and required oxygen (≥40%) or noninvasive ventilation. A total of 400 patients were enrolled between May 19, 2020, and May 18, 2021, and final follow-up was completed in July 2021. Intervention: Patients were randomized to awake prone positioning (n = 205) or usual care without prone positioning (control; n = 195). Main Outcomes and Measures: The primary outcome was endotracheal intubation within 30 days of randomization. The secondary outcomes included mortality at 60 days, days free from invasive mechanical ventilation or noninvasive ventilation at 30 days, days free from the intensive care unit or hospital at 60 days, adverse events, and serious adverse events. Results: Among the 400 patients who were randomized (mean age, 57.6 years [SD, 12.83 years]; 117 [29.3%] were women), all (100%) completed the trial. In the first 4 days after randomization, the median duration of prone positioning was 4.8 h/d (IQR, 1.8 to 8.0 h/d) in the awake prone positioning group vs 0 h/d (IQR, 0 to 0 h/d) in the control group. By day 30, 70 of 205 patients (34.1%) in the prone positioning group were intubated vs 79 of 195 patients (40.5%) in the control group (hazard ratio, 0.81 [95% CI, 0.59 to 1.12], P = .20; absolute difference, -6.37% [95% CI, -15.83% to 3.10%]). Prone positioning did not significantly reduce mortality at 60 days (hazard ratio, 0.93 [95% CI, 0.62 to 1.40], P = .54; absolute difference, -1.15% [95% CI, -9.40% to 7.10%]) and had no significant effect on days free from invasive mechanical ventilation or noninvasive ventilation at 30 days or on days free from the intensive care unit or hospital at 60 days. There were no serious adverse events in either group. In the awake prone positioning group, 21 patients (10%) experienced adverse events and the most frequently reported were musculoskeletal pain or discomfort from prone positioning (13 of 205 patients [6.34%]) and desaturation (2 of 205 patients [0.98%]). There were no reported adverse events in the control group. Conclusions and Relevance: In patients with acute hypoxemic respiratory failure from COVID-19, prone positioning, compared with usual care without prone positioning, did not significantly reduce endotracheal intubation at 30 days. However, the effect size for the primary study outcome was imprecise and does not exclude a clinically important benefit. Trial Registration: ClinicalTrials.gov Identifier: NCT04350723.

BACKGROUND: Restricted visitation policies in acute care settings because of the COVID-19 pandemic have negative consequences. The objective of this scoping review is to identify impacts of restricted visitation policies in acute care settings, and describe perspectives and mitigation approaches among patients, families, and healthcare professionals. METHODS: We searched Medline, Embase, PsycINFO, Healthstar, CINAHL, Cochrane Central Register of Controlled Trials on January 01/2021, unrestricted, for published primary research records reporting any study design. We included secondary (e.g., reviews) and non-research records (e.g., commentaries), and performed manual searches in web-based resources. We excluded records that did not report primary data. Two reviewers independently abstracted data in duplicate. RESULTS: Of 7810 citations, we included 155 records. Sixty-six records (43%) were primary research; 29 (44%) case reports or case series, and 26 (39%) cohort studies; 21 (14%) were literature reviews and 8 (5%) were expert recommendations; 54 (35%) were commentary, editorial, or opinion pieces. Restricted visitation policies impacted coping and daily function (n = 31, 20%) and mental health outcomes (n = 29, 19%) of patients, families, and healthcare professionals. Participants described a need for coping and support (n = 107, 69%), connection and communication (n = 107, 69%), and awareness of state of well-being (n = 101, 65%). Eighty-seven approaches to mitigate impact of restricted visitation were identified, targeting families (n = 61, 70%), patients (n = 51, 59%), and healthcare professionals (n = 40, 46%). CONCLUSIONS: Patients, families, and healthcare professionals were impacted by restricted visitation polices in acute care settings during COVID-19. The consequences of this approach on patients and families are understudied and warrant evaluation of approaches to mitigate their impact. Future pandemic policy development should include the perspectives of patients, families, and healthcare professionals. TRIAL REGISTRATION: The review was registered on PROSPERO (CRD42020221662) and a protocol peer-reviewed prior to data extraction.

PURPOSE: Prone positioning of non-intubated patients with coronavirus disease (COVID-19) and hypoxemic respiratory failure may prevent intubation and improve outcomes. Nevertheless, there are limited data on its feasibility, safety, and physiologic effects. The objective of our study was to assess the tolerability and safety of awake prone positioning in COVID-19 patients with hypoxemic respiratory failure. METHODS: This historical cohort study was performed across four hospitals in Calgary, Canada. Included patients had suspected COVID-19 and hypoxic respiratory failure requiring intensive care unit (ICU) consultation, and underwent awake prone positioning. The duration, frequency, tolerability, and adverse events from prone positioning were recorded. Respiratory parameters were assessed before, during, and after prone positioning. The primary outcome was the tolerability and safety of prone positioning. RESULTS: Seventeen patients (n = 12 ICU, n = 5 hospital ward) were included between April and May 2020. The median (range) number of prone positioning days was 1 (1-7) and the median number of sessions was 2 (1-6) per day. The duration of prone positioning was 75 (30-480) min, and the peripheral oxygen saturation was 91% (84-95) supine and 98% (92-100) prone. Limitations to prone position duration were pain/general discomfort (47%) and delirium (6%); 47% of patients had no limitations. Seven patients (41%) required intubation and two patients (12%) died. CONCLUSIONS: In a small sample, prone positioning non-intubated COVID-19 patients with severe hypoxemia was safe; however, many patients did not tolerate prolonged durations. Although patients had improved oxygenation and respiratory rate in the prone position, many still required intubation. Future studies are required to determine methods to improve the tolerability of awake prone positioning and whether there is an impact on clinical outcomes.
RéSUMé: OBJECTIF: Le positionnement ventral des patients non intubés atteints de coronavirus (COVID-19) et d'insuffisance respiratoire hypoxémique pourrait éviter de devoir les intuber et améliorer leurs pronostics. Nous ne disposons toutefois que de peu de données concernant la faisabilité, la sécurité et les effets physiologiques d'un tel positionnement. L'objectif de notre étude était d'évaluer la tolérabilité et la sécurité du positionnement ventral éveillé chez des patients atteints de la COVID-19 et d'insuffisance respiratoire hypoxémique. MéTHODE: Cette étude de cohorte historique a été réalisée dans 4 hôpitaux de Calgary, au Canada. Les patients inclus avaient une suspicion de COVID-19, souffraient d'insuffisance respiratoire hypoxique nécessitant une consultation à l'unité de soins intensifs (USI), et ont été positionnés sur le ventre éveillés. La durée, la fréquence, la tolérabilité et les événements indésirables liés au positionnement ventral ont été enregistrés. Les paramètres respiratoires étaient évalués avant, pendant et après le positionnement ventral. Les critères d'évaluation principaux étaient la tolérabilité et la sécurité du positionnement ventral. RéSULTATS: Dix-sept patients (n = 12 USI, n = 5 à l'étage) ont été inclus entre avril et mai 2020. Le nombre médian de jours de positionnement ventral était de 1 (fourchette 1-7) et de 2 sessions (fourchette 1-6) par jour. La durée médiane du positionnement ventral était de 75 min (fourchette, 30-480). La saturation en oxygène périphérique médiane en position dorsale était de 91 % (fourchette, 84-95) et de 98 % (fourchette 92-100) en position ventrale. Les obstacles à une durée prolongée de la position ventrale étaient la douleur / l'inconfort général (47%) et le delirium (6%). Au total, 47 % des patients n'ont fait état d'aucun obstacle. Sept patients (41 %) ont nécessité une intubation, et deux patients (12 %) sont décédés. CONCLUSION: Dans un petit échantillon, le positionnement ventral de patients non intubés atteints de COVID-19 et d'hypoxémie grave était sécuritaire, mais plusieurs patients n'ont pas toléré cette position pour une durée prolongée. Bien que l'oxygénation et la fréquence respiratoire des patients étaient améliorées en position ventrale, bon nombre ont tout de même nécessité une intubation. Des études futures sont nécessaires afin de déterminer quelles méthodes amélioreraient la tolérabilité du positionnement ventral éveillé et si cette position a un impact sur les devenirs cliniques.

Many patients with coronavirus disease (COVID-19) will develop acute respiratory distress syndrome (ARDS). Prone positioning is an important non-pharmacologic strategy that should be considered for all invasively ventilated patients with moderate to severe ARDS (including those with COVID-19). Prone positioning offers several physiologic and clinical benefits, including improving hypoxemia, matching ventilation with perfusion, reducing regional hyperinflation, and improving survival. To safely offer prone positioning, appropriate training, simulation, and health system planning should be undertaken. In this review, we offer ten tips, based on the Alberta provincial prone positioning strategy during COVID-19, to safely implement and improve the appropriate use of prone positioning. We provide special considerations for its use during the COVID-19 pandemic or future respiratory pandemics.
RéSUMé: De nombreux patients atteints de la maladie du coronavirus (COVID-19) développeront un syndrome de détresse respiratoire aiguë (SDRA, ARDS en anglais). Le positionnement ventral est une importante stratégie non pharmacologique qui devrait être envisagée pour tous les patients ventilés de manière invasive et souffrant d'un SDRA modéré à grave (y compris ceux atteints de la COVID-19). Le positionnement ventral offre plusieurs avantages physiologiques et cliniques, notamment l'amélioration de l'hypoxémie, une adéquation de la ventilation avec la perfusion, la réduction de l'hyperinflation régionale et l'amélioration de la survie. Pour offrir un positionnement ventral en toute sécurité, une formation, des simulations et une planification des ressources appropriées devraient être entreprises. Dans le cadre de ce compte rendu, nous proposons dix conseils, fondés sur la stratégie provinciale de positionnement ventral de l'Alberta au cours de la COVID-19, afin de mettre en Åuvre et d'améliorer en toute sécurité l'utilisation appropriée du positionnement ventral. Nous décrivons des considérations particulières pour son utilisation pendant la pandémie de COVID-19 ou les futures pandémies respiratoires.

PURPOSE: In response to the rapid spread of SARS-CoV-2, hospitals in Canada enacted temporary visitor restrictions to limit the spread of COVID-19 and preserve personal protective equipment supplies. This study describes the extent, variation, and fluctuation of Canadian adult intensive care unit (ICU) visitation policies before and during the first wave of the COVID-19 pandemic. METHODS: We conducted an environmental scan of Canadian hospital visitation policies throughout the first wave of the pandemic. We conducted a two-phased study analyzing both quantitative and qualitative data. RESULTS: We collected 257 documents with reference to visitation policies (preCOVID, 101 [39%]; midCOVID, 71 [28%]; and lateCOVID, 85 [33%]). Of these 257 documents, 38 (15%) were ICU-specific and 70 (27%) referenced the ICU. Most policies during the midCOVID/lateCOVID pandemic period allowed no visitors with specific exceptions (e.g., end-of-life). Framework analysis revealed five overarching themes: 1) reasons for restricted visitation policies; 2) visitation policies and expectations; 3) exceptions to visitation policy; 4) patient and family-centred care; and 5) communication and transparency. CONCLUSIONS: During the first wave of the COVID-19 pandemic, most Canadian hospitals had public-facing visitor restriction policies with specific exception categories, most commonly for patients at end-of-life, patients requiring assistance, or COVID-19 positive patients (varying from not allowed to case-by-case). Further studies are needed to understand the consistency with which visitation policies were operationalized and how they may have impacted patient- and family-centred care.
RéSUMé: OBJECTIF: En réponse à la propagation rapide du SRAS-CoV-2, les hôpitaux du Canada ont adopté des restrictions temporaires pour les visites afin de limiter la propagation de la COVID-19 et de préserver les stocks d'équipements de protection individuelle. Cette étude décrit l'ampleur, les variations et fluctuations des politiques canadiennes concernant les visites aux unités de soins intensifs (USI) pour adultes avant et pendant la première vague de la pandémie de COVID-19. MéTHODE: Nous avons réalisé une étude de milieu des politiques hospitalières canadiennes concernant les visites tout au long de la première vague de la pandémie. Nous avons mené une étude en deux phases analysant des données quantitatives et qualitatives. RéSULTATS: Nous avons recueilli 257 documents faisant référence aux politiques de visites (pré-COVID, 101 [39 %]; mid-COVID, 71 [28 %]; et COVID-tardif, 85 [33 %]). Sur ces 257 documents, 38 (15 %) étaient spécifiques aux USI et 70 (27 %) faisaient référence aux USI. La plupart des politiques au cours de la période pandémique mid-COVID/COVID-tardif ne permettaient aucune visite sauf exception spécifique (p. ex., fin de vie). L'analyse du cadre a révélé cinq thèmes généraux : 1) les raisons des restrictions des politiques de visites; 2) les politiques et attentes en matière de visites; 3) les exceptions aux politiques de visites; 4) les soins aux patients et centrés sur la famille; et 5) la communication et la transparence. CONCLUSION: Au cours de la première vague de la pandémie de COVID-19, la plupart des hôpitaux canadiens avaient des politiques de restriction des visites s'appliquant au public avec des catégories d'exception spécifiques, le plus souvent pour les patients en fin de vie, les patients nécessitant de l'aide ou les patients COVID-positifs (variant d'une interdiction au cas par cas). D'autres études sont nécessaires pour comprendre l'uniformité avec laquelle les politiques de visites ont été mises en Åuvre et comment elles ont pu avoir une incidence sur les soins centrés sur le patient et la famille.

BACKGROUND: The COVID-19 pandemic has placed sustained demand on health systems globally, and the capacity to provide critical care has been overwhelmed in some jurisdictions. It is unknown which triage criteria for allocation of resources perform best to inform health system decision-making. We sought to summarize and describe existing triage tools and ethical frameworks to aid healthcare decision-making during infectious disease outbreaks. METHODS: We conducted a rapid review of triage criteria and ethical frameworks for the allocation of critical care resources during epidemics and pandemics. We searched Medline, EMBASE, and SCOPUS from inception to November 3, 2020. Full-text screening and data abstraction were conducted independently and in duplicate by three reviewers. Articles were included if they were primary research, an adult critical care setting, and the framework described was related to an infectious disease outbreak. We summarized each triage tool and ethical guidelines or framework including their elements and operating characteristics using descriptive statistics. We assessed the quality of each article with applicable checklists tailored to each study design. RESULTS: From 11,539 unique citations, 697 full-text articles were reviewed and 83 articles were included. Fifty-nine described critical care triage protocols and 25 described ethical frameworks. Of these, four articles described both a protocol and ethical framework. Sixty articles described 52 unique triage criteria (29 algorithm-based, 23 point-based). Few algorithmic- or point-based triage protocols were good predictors of mortality with AUCs ranging from 0.51 (PMEWS) to 0.85 (admitting SOFA > 11). Most published triage protocols included the substantive values of duty to provide care, equity, stewardship and trust, and the procedural value of reason. CONCLUSIONS: This review summarizes available triage protocols and ethical guidelines to provide decision-makers with data to help select and tailor triage tools. Given the uncertainty about how the COVID-19 pandemic will progress and any future pandemics, jurisdictions should prepare by selecting and adapting a triage tool that works best for their circumstances.

OBJECTIVES: The aim of this study was to determine the effects of escalation of respiratory support and prolonged postoperative invasive ventilation on patient-centered outcomes, and identify perioperative factors associated with these 2 respiratory complications. DESIGN: A retrospective cohort analysis of cardiac surgical patients admitted to the cardiothoracic intensive care unit (ICU) between August 2015 and January 2018. Escalation of respiratory support was defined as "unplanned continuous positive airway pressure," "non-invasive ventilation," or "reintubation" after surgery; prolonged invasive ventilation was defined as "invasive ventilation beyond the first 12 hours following surgery." The primary endpoint was the composite of escalation of respiratory support and prolonged ventilation. SETTING: Tertiary cardiothoracic ICU. PARTICIPANTS: A total of 2,098 patients were included and analyzed. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The composite of escalation of support or prolonged ventilation occurred in 509 patients (24.3%). Patients who met the composite had higher mortality (2.9% v 0.1%; p < 0.001) and longer median [interquartile range] length of ICU (2.1 [1.0-4.9] v 0.9 [0.8-1.0] days; p < 0.0001) and hospital (10.6 [8.0-16.0] v 7.2 [6.2-10.0] days; p < 0.0001) stay. Hypoxemia and anemia on admission to ICU were the only 2 factors independently associated with the need for escalation of respiratory support or prolonged invasive ventilation. CONCLUSIONS: Escalation of respiratory support or prolonged invasive ventilation is frequently seen in cardiac surgery patients and is highly associated with increased mortality and morbidity. Hypoxemia and anemia on admission to the ICU are potentially modifiable factors associated with escalation of respiratory support or prolonged invasive ventilation.

BACKGROUND: The Berlin definition of acute respiratory distress syndrome (ARDS) includes only clinical characteristics. Understanding unique patient pathobiology may allow personalized treatment. We aimed to define and describe ARDS phenotypes/endotypes combining clinical and pathophysiologic parameters from a Canadian ARDS cohort. METHODS: A cohort of adult ARDS patients from multiple sites in Calgary, Canada, had plasma cytokine levels and clinical parameters measured in the first 24 h of ICU admission. We used a latent class model (LCM) to group the patients into several ARDS subgroups and identified the features differentiating those subgroups. We then discuss the subgroup effect on 30 day mortality. RESULTS: The LCM suggested three subgroups (n1 = 64, n2 = 86, and n3 = 30), and 23 out of 69 features made these subgroups distinct. The top five discriminating features were IL-8, IL-6, IL-10, TNF-a, and serum lactate. Mortality distinctively varied between subgroups. Individual clinical characteristics within the subgroup associated with mortality included mean PaO2/FiO2 ratio, pneumonia, platelet count, and bicarbonate negatively associated with mortality, while lactate, creatinine, shock, chronic kidney disease, vasopressor/ionotropic use, low GCS at admission, and sepsis were positively associated. IL-8 and Apache II were individual markers strongly associated with mortality (Area Under the Curve = 0.84). PERSPECTIVE: ARDS subgrouping using biomarkers and clinical characteristics is useful for categorizing a heterogeneous condition into several homogenous patient groups. This study found three ARDS subgroups using LCM; each subgroup has a different level of mortality. This model may also apply to developing further trial design, prognostication, and treatment selection.

INTRODUCTION: Hypoxaemic respiratory failure (HRF) affects nearly 15% of critically ill adults admitted to an intensive care unit (ICU). An evidence-based, stakeholder-informed multidisciplinary care pathway (Venting Wisely) was created to standardise the diagnosis and management of patients with HRF and acute respiratory distress syndrome. Successful adherence to the pathway requires a coordinated team-based approach by the clinician team. The overall aim of this study is to describe the acceptability of the Venting Wisely pathway among critical care clinicians. Specifically, this will allow us to (1) better understand the user's experience with the intervention and (2) determine if the intervention was delivered as intended. METHODS AND ANALYSIS: This qualitative study will conduct focus groups with nurse practitioners, physicians, registered nurses and registered respiratory therapists from 17 Alberta ICUs. We will use template analysis to describe the acceptability of a multicomponent care pathway according to seven constructs of acceptability: (1) affective attitude;,(2) burden, (3) ethicality, (4) intervention coherence, (5) opportunity costs, (6) perceived effectiveness and (7) self-efficacy. This study will contribute to a better understanding of the acceptability of the Venting Wisely pathway. Identification of areas of poor acceptability will be used to refine the pathway and implementation strategies as ways to improve adherence to the pathway and promote its sustainability. ETHICS AND DISSEMINATION: The study was approved by the University of Calgary Conjoint Health Research Ethics Board. The results will be submitted for publication in a peer-reviewed journal and presented at a scientific conference. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT04744298.

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) is an intervention used in critically ill patients with severe cardiopulmonary failure that is expensive and resource intensive and requires specialised care. There remains a significant practice variation in its application. This systematic review will assess the evidence for key performance indicators (KPIs) in ECMO. METHODS AND ANALYSIS: We will search Ovid MEDLINE, Ovid EMBASE, Cumulative Index to Nursing and Allied Health Literature and the Cochrane Library including the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials and databases from the National Information Center of Health Services Research and Health Care Technology, for studies involving KPIs in ECMO. We will rate methodological quality using the Newcastle-Ottawa Quality Assessment Scale. Randomized controlled trials (RCTs) will be evaluated with the Cochrane Risk of Bias tool, and qualitative studies will be evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN checklist). Grey literature sources will be searched for technical reports, practice guidelines and conference proceedings. We will identify relevant organisations, industry leaders and non-profit organisations that represent key opinion leads in the use of ECMO. We will search the Agency of Healthcare Research and Quality National Quality Measures Clearinghouse for ECMO-related KPIs. Studies will be included if they contain quality measures that occur in critically ill patients and are associated with ECMO. The analysis will be primarily descriptive. Each KPI will be evaluated for importance, scientific acceptability, utility and feasibility using the four criteria proposed by the US Strategic Framework Board for a National Quality Measurement and Reporting System. Finally, KPIs will be evaluated for their potential operational characteristics, their potential to be integrated into electronic medical records and their affordability, if applicable. ETHICS AND DISSEMINATION: Ethical approval is not required as no primary data will be collected. Findings will be published in a peer-reviewed journal and presented at academic. PROSPERO REGISTRATION NUMBER: 9 August 2022. CRD42022349910.

BACKGROUND: A significant gap exists between ideal evidence-based practice and real-world application of evidence-informed therapies for patients with hypoxaemic respiratory failure (HRF) and acute respiratory distress syndrome (ARDS). Pathways can improve the quality of care provided by helping integrate and organise the use of evidence informed practices, but barriers exist that can influence their adoption and successful implementation. We sought to identify barriers to the implementation of a best practice care pathway for HRF and ARDS and design an implementation science-based strategy targeting these barriers that is tailored to the critical care setting. METHODS: The intervention assessed was a previously described multidisciplinary, evidence-based, stakeholder-informed, integrated care pathway for HRF and ARDS. A survey questionnaire (12 open text questions) was administered to intensive care unit (ICU) clinicians (physicians, nurses, respiratory therapists) in 17 adult ICUs across Alberta. The Behaviour Change Wheel, capability, opportunity, motivation - behaviour components, and Theoretical Domains Framework (TDF) were used to perform qualitative analysis on open text responses to identify barriers to the use of the pathway. Behaviour change technique (BCT) taxonomy, and Affordability, Practicality, Effectiveness and cost-effectiveness, Acceptability, Side effects and safety and Equity (APEASE) criteria were used to design an implementation science-based strategy specific to the critical care context. RESULTS: Survey responses (692) resulted in 16 belief statements and 9 themes with 9 relevant TDF domains. Differences in responses between clinician professional group and hospital setting were common. Based on intervention functions linked to each belief statement and its relevant TDF domain, 26 candidate BCTs were identified and evaluated using APEASE criteria. 23 BCTs were selected and grouped to form 8 key components of a final strategy: Audit and feedback, education, training, clinical decision support, site champions, reminders, implementation support and empowerment. The final strategy was described using the template for intervention description and replication framework. CONCLUSIONS: Barriers to a best practice care pathway were identified and were amenable to the design of an implementation science-based mitigation strategy. Future work will evaluate the ability of this strategy to improve quality of care by assessing clinician behaviour change via better adherence to evidence-based care.

INTRODUCTION: Titrated application of positive end-expiratory pressure (PEEP) is an important part of any mechanical ventilation strategy. However, the method by which the optimal PEEP is determined and titrated varies widely. Methods for determining optimal PEEP have been assessed using a variety of different study designs and patient populations. We will conduct a scoping review to systematically identify all methods for determining optimal PEEP, and to identify the patient populations, outcomes measured and study designs used for each method. The goal will be to identify gaps in the optimal PEEP literature and identify areas where there may be an opportunity to further systematically synthesise and meta-analyse existing literature. METHODS AND ANALYSIS: Using scoping review methodology, we will generate a comprehensive search strategy based on inclusion and exclusion criteria generated using the population, concept, context framework. Five different databases will be searched (MEDLINE, EMBASE, CENTRAL, Web of Science and Scopus). Three investigators will independently screen titles and abstracts, and two investigators will independently complete full-text review and data extraction. Included citations will be categorised in terms of PEEP method, study design, patient population and outcomes measured. The methods for PEEP titration will be described in detail, including strengths and limitations. ETHICS AND DISSEMINATION: Given this is a synthesis of existing literature, ethics approval is not required. The results will be disseminated to stakeholders via presentation at local, regional and national levels, as well as publication in a high-impact critical care journal. There is also the potential to impact local clinical care protocols and inform broader clinical practice guidelines undertaken by societies.

Objective: To describe a study protocol and statistical analysis plan (SAP) for the identification and treatment of hypoxemic respiratory failure (HRF) and acute respiratory distress syndrome (ARDS) with protection, paralysis, and proning (TheraPPP) study prior to completion of recruitment, electronic data retrieval, and analysis of any data. Design: TheraPPP is a stepped-wedge cluster randomised study evaluating a care pathway for HRF and ARDS patients. This is a type-1 hybrid effectiveness-implementation study design evaluating both intervention effectiveness and implementation; however primarily powered for the effectiveness outcome. Setting: Seventeen adult intensive care units (ICUs) across Alberta, Canada. Participants: We estimate a sample size of 18816 mechanically ventilated patients, with 11424 patients preimplementation and 7392 patients postimplementation. We estimate 2688 sustained ARDS patients within our study cohort. Intervention: An evidence-based, stakeholder-informed, multidisciplinary care pathway called Venting Wisely that standardises diagnosis and treatment of HRF and ARDS patients. Main outcome measures: The primary outcome is 28-day ventilator-free days (VFDs). The primary analysis will compare the mean 28-day VFDs preimplementation and postimplementation using a mixed-effects linear regression model. Prespecified subgroups include sex, age, HRF, ARDS, COVID-19, cardiac surgery, body mass index, height, illness acuity, and ICU volume. Results: This protocol and SAP are reported using the Standard Protocol Items: Recommendations for Interventional Trials guidance and the Guidelines for the Content of Statistical Analysis Plans in Clinical Trials. The study received ethics approval and was registered (ClinicalTrials.gov-NCT04744298) prior to patient enrolment. Conclusions: TheraPPP will evaluate the effectiveness and implementation of an HRF and ARDS care pathway.
