What Are the Care Needs of Families Experiencing Sudden Cardiac Arrest? A Survivor- and Family-Performed Systematic Review, Qualitative Meta-Synthesis, and Clinical Practice Recommendations.

INTRODUCTION: Cardiac arrest care systems are being designed and implemented to address patients', family members', and survivors' care needs. We conducted a systematic review and a meta-synthesis to understand family experiences and care needs during cardiac arrest care to create treatment recommendations. METHODS: We searched eight electronic databases to identify articles. Study findings were extracted, coded and synthesized. Confidence in the quality, coherence, relevance, and adequacy of data underpinning the resulting findings was assessed using GRADE-CERQual methods. RESULTS: In total 4181 studies were screened, and 39 met our inclusion criteria; these studies enrolled 215 survivors and 418 family participants-which includes both co-survivors and bereaved family members. From these studies findings and participant data we identified 5 major analytical themes: (1) When the crisis begins we must respond; (2) Anguish from uncertainty, we need to understand; (3) Partnering in care, we have much to offer; (4) The crisis surrounding the victim, ignore us, the family, no longer; (5) Our family's emergency is not over, now is when we need help the most. Confidence in the evidence statements are provided along with our review findings. DISCUSSION: The family experience of cardiac arrest care is often chaotic, distressing, complex and the aftereffects are long-lasting. Patient and family experiences could be improved for many people. High certainty family care needs identified in this review include rapid recognition and response, improved information sharing, more effective communication, supported presence and participation, or supported absence, and psychological aftercare.

The experience of online cardiac arrest video use for education and research: A qualitative interview study completed in partnership with survivors and co-survivors.

Background: Swift recognition of cardiac arrest is required for survival, however failure to recognize (and delayed response) is common. Studying online cardiac arrest videos may aid recognition, however the ethical implications of this are unknown. We examined their use from the perspective of persons with lived experience of cardiac arrest, seeking to understand the experience of having one's cardiac arrest recorded and available online. Methods: We gathered qualitative data using focused interviews of persons affected by cardiac arrest. Inductive thematic analysis was performed, as well as a deductive ethical analysis. Co-researcher survivors and co-survivors were involved in all stages of this project. Findings: We identified themes of 'shock, hurt and helplessness' and 'surreality and reality' to describe the experience of having one's (or a family member's) cardiac arrest captured and distributed online. Participants provided guidance on the use of online videos for education and research, emphasising beneficence, autonomy, non-maleficence, and justice. Conclusions: Finding one's own, or a family member's cardiac arrest video online is shocking and potentially harmful for families. If ethical principles are followed however, there may be acceptable procedures for the use of online videos of cardiac arrest for education or research purposes. The careful use of online videos of cardiac arrest for education and research may help improve recognition and response, though additional research is required to confirm or refute this claim.

Caring for the invisible and forgotten: a qualitative document analysis and experience-based co-design project to improve the care of families experiencing out-of-hospital cardiac arrest.

OBJECTIVES: The objectives of this project were to collect and analyze clinical governance documents related to family-centred care and cardiac arrest care in Canadian EMS organizations; and to improve the family-centredness of out-of-hospital cardiac arrest care through experience-based co-design. METHODS: We conducted qualitative document analysis of Canadian EMS clinical governance documents related to family-centred and cardiac arrest care, combining elements of content and thematic analysis methods. We then used experience-based co-design to develop a family-centred out-of-hospital cardiac arrest care policy and procedure template. RESULTS: Thirty-five Canadian EMS organizations responded to our requests, representing service area coverage for 80% of the Canadian population. Twenty documents were obtained for review and six overarching themes were identified: addressing family in event of in-home death, importance of family, family member escort, provider discretion and family presence discouraged. Informed by our qualitative analysis we then co-designed a policy and procedure template was created that prioritizes patient care while promotes family-centredness. CONCLUSIONS: There were few directives to support family-centred care by Canadian EMS organizations. A family-centred out-of-hospital cardiac arrest care policy and procedure template was developed using experience-based co-design to assist EMS organizations improve the family-centredness of out-of-hospital cardiac arrest care.

RéSUMé: OBJECTIFS: Les objectifs de ce projet étaient de recueillir et d'analyser des documents de gouvernance clinique liés aux soins centrés sur la famille et aux soins de l'arrêt cardiaque dans les organisations canadiennes de SMU; et d'améliorer le caractère centré sur la famille des soins en cas d'arrêt cardiaque à l'extérieur de l'hôpital grâce à une co-conception fondée sur l'expérience. MéTHODES: Nous avons effectué une analyse qualitative des documents de gouvernance clinique des SMU canadiens liés aux soins axés sur la famille et aux arrêts cardiaques, en combinant des éléments de contenu et des méthodes d'analyse thématique. Nous avons ensuite utilisé la co-conception fondée sur l'expérience pour élaborer un modèle de politique et de procédure de soins en cas d'arrêt cardiaque centrés sur la famille en dehors de l'hôpital. RéSULTATS: Trente-cinq organisations Canadiennes de SMU ont répondu à nos demandes, ce qui représente une couverture de zone de service pour 80 % de la population canadienne. Vingt documents ont été obtenus aux fins d'examen et six thèmes principaux ont été cernés: s'adresser à la famille en cas de décès à domicile, l'importance de la famille, accompagnement d'un membre de la famille, la discrétion du fournisseur et la présence de la famille découragée. Éclairés par notre analyse qualitative, nous avons ensuite co-conçu un modèle de politique et de procédure qui priorise les soins aux patients tout en favorisant l'orientation familial. CONCLUSIONS: Il y avait peu de directives pour soutenir les soins axés sur la famille par les organisations canadiennes de SMU. Un modèle de politique de soins d'arrêt cardiaque centré sur la famille a été élaboré à l'aide d'une co-conception basée sur l'expérience pour aider les organisations de SMU à améliorer l'orientation familiale des soins en cas d'arrêt cardiaque hors hôpital.

Simulation in cardiac critical care.

Medical simulation is a broad topic but at its core is defined as any effort to realistically reproduce a clinical procedure, team, or situation. Its goal is to allow risk-free practice-until-perfect, and in doing so, augment performance, efficiency, and safety. In medicine, even complex clinical situations can be dissected into reproducible parts that may be repeated and mastered, and these iterative improvements can add up to major gains. With our modern cardiac intensive care units treating a growing number of medically complex patients, the need for well-trained personnel, streamlined care pathways, and quality teamwork is imperative for improved patient outcomes. Simulation is therefore a potentially life-saving tool relevant to anyone working in cardiac intensive care. Accordingly, we believe that simulation is a priority for cardiac intensive care, not just a luxury. We offer the following primer on simulation in the cardiac intensive care environment.

Assessing on-line medical education resources: A primer for acute care medical professionals and others.

The internet is increasingly used to propagate medical education, debate, and even disinformation. Therefore, this primer aims to help acute care medical professionals, as well as the public. This is because we all need to be able to critically appraise digital products, appraise content producers, and reflect upon our own on-line presence. This article discusses the challenges and opportunities associated with online medical resources. We then review Free Open Access Medical Education (FOAMed) and the key tools used to assess the trustworthiness of on-line medical products. Specifically, after discussing the pros and cons of traditional academic quality metrics, we compare and contrast the Social Media Index, the ALiEM AIR score, the Revised METRIQ Score, and gestalt. We also discuss internet search engines, peer review, and the important message behind the seemingly tongue-in-cheek Kardashian Index. Hopefully, this primer bolsters basic digital literacy and helps trainees, practitioners, and the public locate useful and reliable on-line resources. Importantly, we highlight the continued importance of traditional academic medicine and primary source publications.

Mortality and Pulmonary Embolism in Acute Respiratory Distress Syndrome From COVID-19 vs. Non-COVID-19.

Purpose: There may be a difference in respiratory mechanics, inflammatory markers, and pulmonary emboli in COVID-19 associated ARDS vs. ARDS from other etiologies. Our purpose was to determine differences in respiratory mechanics, inflammatory markers, and incidence of pulmonary embolism in patients with and without COVID-19 associated ARDS admitted in the same period and treated with a similar ventilation strategy. Methods: A cohort study of COVID-19 associated ARDS and non COVID-19 patients in a Saudi Arabian center between June 1 and 15, 2020. We measured respiratory mechanics (ventilatory ratio (VR), recruitability index (RI), markers of inflammation, and computed tomography pulmonary angiograms. Results: Forty-two patients with COVID-19 and 43 non-COVID patients with ARDS comprised the cohort. The incidence of "recruitable" patients using the recruitment/inflation ratio was slightly lower in COVID-19 patients (62 vs. 86%; p = 0.01). Fifteen COVID-19 ARDS patients (35.7%) developed a pulmonary embolism as compared to 4 (9.3%) in other ARDS patients (p = 0.003). In COVID-19 patients, a D-Dimer ≥ 5.0 mcg/ml had a 73% (95% CI 45-92%) sensitivity and 89% (95% CI 71-98%) specificity for predicting pulmonary embolism. Crude 60-day mortality was higher in COVID-19 patients (35 vs. 15%; p = 0.039) but three multivariate analysis showed that independent predictors of 60-day mortality included the ventilatory ratio (OR 3.67, 95% CI 1.61-8.35), PaO2/FIO2 ratio (OR 0.93; 95% CI 0.87-0.99), IL-6 (OR 1.02, 95% CI 1.00-1.03), and D-dimer (OR 7.26, 95% CI 1.11-47.30) but not COVID-19 infection. Conclusion: COVID-19 patients were slightly less recruitable and had a higher incidence of pulmonary embolism than those with ARDS from other etiologies. A high D-dimer was predictive of pulmonary embolism in COVID-19 patients. COVID-19 infection was not an independent predictor of 60-day mortality in the presence of ARDS.

A 6-Year Thematic Review of Reported Incidents Associated With Cardiopulmonary Resuscitation Calls in a United Kingdom Hospital.

BACKGROUND: Critical incident reporting can be applied to cardiopulmonary resuscitation (CPR) events as a means of reducing further occurrences. We hypothesized that local CPR-related events might follow patterns only seen after a long period of analysis. DESIGN: We reviewed 6 years of local incidents associated with cardiac arrest calls. The following search terms were used to identify actual or potential resuscitation events: "resuscitation," "cardio-pulmonary," "CPR," "arrest," "heart attack," "DNR," "DNAR," "DNACPR," "Crash," "2222." All identified incidents were independently reviewed and categorized, looking for identifiable patterns. SETTING: Nottingham University Hospitals is a large UK tertiary referral teaching hospital. RESULTS: A total of 1017 reports were identified, relating to 1069 categorizable incidents. During the same time, there were approximately 1350 cardiac arrest calls, although it should be noted that many arrest-related incidents were not associated with cardiac arrest call (e.g., failure to have the correct equipment available in the event of a cardiac arrest). Incidents could be broadly classified into 10 thematic areas: no identifiable incident (n = 189; 18%), failure to rescue (n = 133; 12%), staffing concerns (n = 134; 13%), equipment/drug concerns (n = 133; 12%), communication issues (n = 122; 10%), do-not-attempt-CPR decisions (n = 101; 9%), appropriateness of patient location or transfer (n = 96; 9%), concerns that the arrest may have been iatrogenic (n = 76; 7%), patient or staff injury (n = 43; 4%), and miscellaneous (n = 52; 5%). Specific patterns of events were seen within each category. CONCLUSIONS: By reviewing incidents, we were able to identify patterns only noticeable over a long time frame, which may be amenable to intervention. Our findings may be generalizable to other centers or encourage others to undertake this exercise themselves.

Optic Nerve Sheath Diameter Ultrasound for Raised Intracranial Pressure: A Literature Review and Meta-analysis of its Diagnostic Accuracy.

Optic nerve sheath diameter (ONSD) ultrasound is becoming increasingly more popular for estimating raised intracranial pressure (ICP). We performed a systematic review and analysis of the diagnostic accuracy of ONSD when compared to the standard invasive ICP measurement. METHOD: We performed a systematic search of PUBMED and EMBASE for studies including adult patients with suspected elevated ICP and comparing sonographic ONSD measurement to a standard invasive method. Quality of studies was assessed using the QUADAS-2 tool by two independent authors. We used a bivariate model of random effects to summarize pooled sensitivity, specificity, and diagnostic odds ratio (DOR). Heterogeneity was investigated by meta-regression and sub-group analyses. RESULTS: We included 18 prospective studies (16 studies including 619 patients for primary outcome). Only one study was of low quality, and there was no apparent publication bias. Pooled sensitivity was 0.9 [95% confidence intervals (CI): 0.85-0.94], specificity was 0.85 (95% CI: 0.8-0.89), and DOR was 46.7 (95% CI: 26.2-83.2) with partial evidence of heterogeneity. The Area-Under-the-Curve of the summary Receiver-Operator-Curve was 0.93 (95% CI: 0.91-0.95, P < .05). No covariates were significant in the meta-regression. Subgroup analysis of severe traumatic brain injury and parenchymal ICP found no heterogeneity. ICP and ONSD had a correlation coefficient of 0.7 (95% CI: 0.63-0.76, P < .05). CONCLUSION: ONSD is a useful adjunct in ICP evaluation but is currently not a replacement for invasive methods where they are feasible.

Electroencephalogram patterns in critical care: A primer for acute care doctors.

Electroencephalograms are commonly ordered by acute care doctors but not always understood. Other reviews have covered when and how to perform electroencephalograms. This primer has a different, unique, and complementary goal. We review basic electroencephalogram interpretation and terminology for nonexperts. Our goal is to encourage common understanding, facilitate inter specialty collaboration, dispel common misunderstandings, and inform the current and future use of this precious resource. This primer is categorically not to replace the expert neurologist or technician. Quite the contrary, it should help explain how nuanced electroencephalogram can be, and why indiscriminate electroencephalogram is inappropriate. Some might argue not to teach nonexperts lest they overestimate their abilities or reach. We humbly submit that it is even more inappropriate to not know the basics of a test that is ordered frequently and resource intensive. We cover the characteristics of the "normal" electroencephalogram, electroencephalogram slowing, periodic epileptiform discharges (and its subtypes), burst suppression, and electrographic seizures (and its subtypes). Alongside characteristic electroencephalogram findings, we provide clinical pearls. These should further explain what the reporter is communicating and whether additional testing is beneficial. Along with teaching the basics and whetting the appetite of the general clinician, this resource could increase mutual understanding and mutual appreciation between those who order electroencephalograms and those who interpret them. While there is more to electroencephalogram than can be delivered via a single concise primer, it offers a multidisciplinary starting point for those interested in the present and future of this commonly ordered test.

Critical care ultrasound training: a survey exploring the "education gap" between potential and reality in Canada.

BACKGROUND: Critical care ultrasound (CCUS) is now a core competency for Canadian critical care medicine (CCM) physicians, but little is known about what education is delivered, how competence is assessed, and what challenges exist. We evaluated the Canadian CCUS education landscape and compared it against published recommendations. METHODS: A 23-item survey was developed and incorporated a literature review, national recommendations, and expert input. It was sent in the spring of 2019 to all 13 Canadian Adult CCM training programs via their respective program directors. Three months were allowed for data collection and descriptive statistics were compiled. RESULTS: Eleven of 13 (85%) programs responded, of which only 7/11 (64%) followed national recommendations. Curricula differed, as did how education was delivered: 8/11 (72%) used hands-on training; 7/11 (64%) used educational rounds; 5/11 (45%) used image interpretation sessions, and 5/11 (45%) used scan-based feedback. All 11 employed academic half-days, but only 7/11 (64%) used experience gained during clinical service. Only 2/11 (18%) delivered multiday courses, and 2/11 (18%) had mandatory ultrasound rotations. Most programs had only 1 or 2 local CCUS expert-champions, and only 4/11 (36%) assessed learner competency. Common barriers included educators receiving insufficient time and/or support. CONCLUSIONS: Our national survey is the first in Canada to explore CCUS education in critical care. It suggests that while CCUS education is rapidly developing, gaps persist. These include variation in curriculum and delivery, insufficient access to experts, and support for educators.

What are the care needs of families experiencing cardiac arrest?: A survivor and family led scoping review.

AIM: The sudden and unexpected cardiac arrest of a family member can be a grief-filled and life-altering event. Every year many hundreds of thousands of families experience the cardiac arrest of a family member. However, care of the family during the cardiac arrest and afteris poorly understood and incompletely described. This review has been performed with persons with lived experience of cardiac arrest to describe, "What are the needs of families experiencing cardiac arrest?" from the moment of collapse until the outcome is known. METHODS: This review was guided by specific methodological framework and reporting items (PRISMA-ScR) as well as best practices in patient and public involvement in research and reporting (GRIPP2). A search strategy was developed for eight online databases and a grey literature review. Two reviewers independently assessed all articles for inclusion and extracted relevant study information. RESULTS: We included 47 articles examining the experience and care needs of families experiencing cardiac arrest of a family member. Forty one articles were analysed as six represented duplicate data. Ten family care need themes were identified across five domains. The domains and themes transcended cardiac arrest setting, aetiology, family-member age and family composition. The five domains were i) focus on the family member in cardiac arrest, ii) collaboration of the resuscitation team and family, iii) consideration of family context, iv) family post-resuscitation needs, and v) dedicated policies and procedures. We propose a conceptual model of family centred cardiac arrest. CONCLUSION: Our review provides a comprehensive mapping and description of the experience of families and their care needs during the cardiac arrest of a family-member. Furthermore, our review was conducted with co-investigators and collaborators with lived experience of cardiac arrest (survivors and family members of survivors and non-survivors alike). The conceptual framework of family centred cardiac arrest care presented may aid resuscitation scientists and providers in adopting greater family centeredness to their work.

Anti-N-methyl-d-aspartate receptor encephalitis: A primer for acute care healthcare professionals.

This primer summarizes the diagnosis, treatment, complications, and prognosis of anti-N-methyl-d-aspartate receptor encephalitis for healthcare professionals, especially those in acute care specialities. Anti-N-methyl-d-aspartate receptor encephalitis is an immune-mediated encephalitis that is classically paraneoplastic and associated with ovarian teratomas in young women. Other less common neoplastic triggers include testicular cancers, Hodgkin lymphoma, lung and breast cancers. It may also be triggered by infection, occurring as a para-infectious phenomenon, seen most commonly after herpes simplex-1 encephalitis. Presentation varies but typically consists of behavioural and cognitive manifestations, seizures, dysautonomia, movement disorders, central hypoventilation, and coma, necessitating intensive care unit admission. Diagnosis of anti-N-methyl-d-aspartate receptor encephalitis requires high clinical suspicion plus ancillary testing, the most sensitive being cerebrospinal fluid analysis for anti-N-methyl-d-aspartate receptor antibodies. Imaging in search of an ovarian teratoma should be exhaustive and tumours need to be surgically treated. Treatment should be expeditious with pulsed steroids and either plasma exchange or intravenous immunoglobulin. Second-line treatments include intravenous rituximab, cyclophosphamide, azathioprine, and intrathecal methotrexate. Most patients recover to be functionally independent, but the in-hospital course can be months long followed by extensive rehabilitation. Given the lengthy course of illness, we explain why education and debriefing are important for staff, and where families can obtain additional help.

Therapeutic plasma exchange in patients with life-threatening COVID-19: a randomised controlled clinical trial.

Assessment of efficacy of therapeutic plasma exchange (TPE) following life-threatening COVID-19. This was an open-label, randomised clinical trial of ICU patients with life-threatening COVID-19 (positive RT-qPCR plus ARDS, sepsis, organ failure, hyperinflammation). Study was terminated after 87/120 patients enrolled. Standard treatment plus TPE (n = 43) versus standard treatment (n = 44), and stratified by PaO2/FiO2 ratio (>150 vs. ≤150), were compared. Primary outcomes were 35-day mortality and TPE safety. Secondary outcomes were association between TPE and mortality, improvement in SOFA score, change in inflammatory biomarkers, days on mechanical ventilation (MV), and ICU length of stay (LOS). Eighty-seven patients [median age 49 (IQR 34-63) years; 82.8% male] were randomised (44 standard care; 43 standard care plus TPE). Days on MV (P = 0.007) and ICU LOS (P = 0.02) were lower in the TPE group. 35-Day mortality was non-significantly lower in the TPE group (20.9% vs. 34.1%; Kaplan-Meier, P = 0.582). TPE was associated with increased lymphocytes and ADAMTS-13 activity and decreased serum lactate, lactate dehydrogenase, ferritin, d-dimers and interleukin-6. Multivariable regression analysis provided several predictors of 35-day mortality: PaO2/FiO2 ratio (HR, 0.98, 95% CI 0.96-1.00; P = 0.02]; ADAMTS-13 activity (HR, 0.89, 95% CI 0.82-0.98; P = 0.01); pulmonary embolism (HR, 3.57, 95% CI 1.43-8.92; P = 0.007). Post-hoc analysis revealed a significant reduction in SOFA score for TPE patients (P < 0.05). In critically-ill COVID-19 patients, addition of TPE to standard ICU therapy was associated with faster clinical recovery and no increased 35-day mortality.

Delayed intensive care unit admission from the emergency department: impact on patient outcomes. A retrospective study. / Retardo na transferência do pronto-socorro para a unidade de terapia intensiva: impacto nos desfechos do paciente. Um estudo retrospectivo.

OBJECTIVE: To study the impact of delayed admission by more than 4 hours on the outcomes of critically ill patients. METHODS: This was a retrospective observational study in which adult patients admitted directly from the emergency department to the intensive care unit were divided into two groups: Timely Admission if they were admitted within 4 hours and Delayed Admission if admission was delayed for more than 4 hours. Intensive care unit length of stay and hospital/intensive care unit mortality were compared between the groups. Propensity score matching was performed to correct for imbalances. Logistic regression analysis was used to explore delayed admission as an independent risk factor for intensive care unit mortality. RESULTS: During the study period, 1,887 patients were admitted directly from the emergency department to the intensive care unit, with 42% being delayed admissions. Delayed patients had significantly longer intensive care unit lengths of stay and higher intensive care unit and hospital mortality. These results were persistent after propensity score matching of the groups. Delayed admission was an independent risk factor for intensive care unit mortality (OR = 2.6; 95%CI 1.9 - 3.5; p < 0.001). The association of delay and intensive care unit mortality emerged after a delay of 2 hours and was highest after a delay of 4 hours. CONCLUSION: Delayed admission to the intensive care unit from the emergency department is an independent risk factor for intensive care unit mortality, with the strongest association being after a delay of 4 hours.

OBJETIVO: Estudar o impacto do retardo na admissão à unidade de terapia intensiva em mais do que 4 horas nos desfechos de pacientes críticos. MÉTODOS: Este foi um estudo observacional retrospectivo, no qual pacientes adultos admitidos diretamente do pronto-socorro para a unidade de terapia intensiva foram divididos em dois grupos: Tempo Adequado, se admitidos dentro de 4 horas, e Admissão Retardada, nos casos em que a admissão demorou mais do que 4 horas para ocorrer. Compararam-se, entre os grupos, o tempo de permanência na unidade de terapia intensiva e a taxa de mortalidade na unidade de terapia intensiva e no hospital. Foi realizado pareamento por escore de propensão para correção de desequilíbrios. Utilizou-se uma análise de regressão logística para explorar retardo da admissão como fator independente de risco para mortalidade na unidade de terapia intensiva. RESULTADOS: Durante o período do estudo, 1.887 pacientes foram admitidos diretamente do pronto-socorro para a unidade de terapia intensiva, sendo que 42% dessas admissões foram retardadas. Os pacientes com retardo tiveram permanências na unidade de terapia intensiva significantemente mais longas e maior mortalidade na unidade de terapia intensiva e no hospital. Esses resultados persistiram após pareamento dos grupos por escore de propensão. O retardo da admissão foi fator independente de risco para mortalidade na unidade de terapia intensiva (RC = 2,6; IC95% 1,9 - 3,5; p < 0,001). A associação de retardo e mortalidade na unidade de terapia intensiva surgiu após período de retardo de 2 horas e foi mais alta após período de retardo de 4 horas. CONCLUSÃO: O retardo da admissão do pronto-socorro para a unidade de terapia intensiva é fator de risco independente para mortalidade na unidade de terapia intensiva, sendo a associação mais forte após retardo de 4 horas.

COVID-19 with spontaneous pneumothorax, pneumomediastinum, and subcutaneous emphysema in the intensive care unit: Two case reports.

Real-Time-reverse-transcription-Polymerase-Chain-Reaction from nasopharyngeal swabs and chest computed tomography (CT) depicting typically bilateral ground-glass opacities with a peripheral and/or posterior distribution are mandatory in the diagnosis of COVID-19. COVID-19 pneumonia may present though with atypical features such as pleural and pericardial effusions, lymphadenopathy, cavitations, and CT halo sign. In these two case-reports, COVID-19 presented as pneumothorax, pneumomediastinum and subcutaneous emphysema in critically ill patients. These disorders may require treatment or can be even self-limiting. Clinicians should be aware of their potential effects on the cardiorespiratory status of critically ill COVID-19 patients. Finally, pneumothorax can be promptly diagnosed by means of lung ultrasound. Although operator dependent, lung ultrasound is a useful bedside diagnostic tool that could alleviate the risk of cross-infection related to COVID-19 patient transport.

Development of a critical care ultrasound curriculum using a mixed-methods needs assessment and engagement of frontline healthcare professionals.

PURPOSE: Experts recommend that critical care medicine (CCM) practitioners should be adept at critical care ultrasound (CCUS). Published surveys highlight that many institutions have no deliberate strategy, no formalized curriculum, and insufficient engagement of CCM faculty and trainees. Consequently, proficiency is non-uniform. Accordingly, we performed a needs assessment to develop an inter-professional standardized CCUS curriculum as a foundation towards universal basic fluency. METHODS: Mixed-methods study of CCM trainees, attendings, and nurse practitioners working across five academic and community medical-surgical intensive care units in Edmonton, Alberta. We used qualitative focus groups followed by quantitative surveys to explore, refine, and integrate results into a curriculum framework. RESULTS: Focus groups with 19 inter-professional practitioners identified major themes including perceived benefits, learning limitations, priorities, perceived risks, characteristics of effective instruction, ensuring long-term success, and achieving competency. Sub-themes highlighted rapid attrition of skill following one- to two-day workshops, lack of skilled faculty, lack of longitudinal training, and the need for site-based mentorship. Thirty-five practitioners (35/70: 50%) completed the survey. Prior training included workshops (16/35; 46%) and self-teaching (11/35; 31%). Eleven percent (4/35) described concerns about potential errors in CCUS performance. The survey helped to refine resources, content, delivery, and assessment. Integration of qualitative and quantitative findings produced a comprehensive curriculum framework. CONCLUSION: Building on published recommendations, our needs assessment identified additional priorities for a CCUS curriculum framework. Specifically, there is a perceived loss of skills following short workshops and insufficient strategies to sustain learning. Addressing these deficits could narrow the gap between national recommendations and frontline needs.

RéSUMé: OBJECTIF: Les experts recommandent que les intensivistes soient habiles en échographie aux soins intensifs. Les sondages publiés révèlent que de nombreux établissements ne possèdent pas de stratégie réfléchie ni de curriculum formalisé en échographie, tout en souffrant d'un manque d'implication du corps professoral et des résidents. Les aptitudes ne sont donc pas uniformes. C'est pourquoi nous avons réalisé une évaluation des besoins afin de mettre au point un curriculum interprofessionnel standardisé en échographie aux soins intensifs qui servira de fondation vers une maîtrise des aptitudes de bases universelles. MéTHODE: Nous avons réalisé une étude en méthodes mixtes auprès de résidents, de patrons et d'infirmiers et infirmières praticiens en soins intensifs travaillant dans cinq unités de soins intensifs médico-chirurgicaux universitaires et communautaires à Edmonton, en Alberta. Nous avons formé des groupes de réflexion qualitatifs puis avons réalisé des sondages quantitatifs afin d'explorer, d'approfondir et d'intégrer nos résultats dans un cadre de curriculum. RéSULTATS: Des groupes de réflexion composés de 19 praticiens interprofessionnels ont identifié des thèmes majeurs, notamment les avantages perçus, les obstacles à l'apprentissage, les priorités, les risques perçus, les caractéristiques d'un enseignement efficace, l'assurance d'un succès à long terme et l'acquisition des compétences. Les sous-thèmes ont mis en lumière une attrition rapide des compétences après des ateliers d'un ou deux jours, le manque d'enseignants compétents, le manque de formation longitudinale, et le besoin de mentorat sur le lieu de travail. Trente-cinq praticiens (35/70; 50 %) ont répondu au sondage. Les formations antérieures incluaient des ateliers (16/35; 46 %) et de l'auto-apprentissage (11/35; 31 %). Onze pourcent (4/35) des répondants ont fait part d'inquiétudes concernant les erreurs potentielles dans la performance de l'échographie aux soins intensifs. Le sondage a permis de raffiner les ressources, le contenu, la livraison et l'évaluation. L'intégration des résultats qualitatifs et quantitatifs a permis de réaliser un cadre exhaustif de curriculum. CONCLUSION: En nous appuyant sur les recommandations publiées, notre évaluation des besoins a identifié des priorités supplémentaires pour encadrer une formation d'échographie destinée aux soins intensifs. Plus spécifiquement, il existe une perte perçue des compétences à la suite d'ateliers courts et il manque de stratégies pour soutenir l'apprentissage. En palliant ces manques, il pourrait être possible de réduire le fossé entre les recommandations nationales et les besoins en première ligne.
