Triage of Critically Ill Patients: Characteristics and Outcomes of Patients Refused as Too Well for Intensive Care.

BACKGROUND: The appropriate selection of patients for the intensive care unit (ICU) is a concern in acute care settings. However, the description of patients deemed too well for the ICU has been rarely reported. METHODS: We conducted a single-centre retrospective observational study of all patients either deemed "too well" for or admitted to the ICU during one year. Refused patients were screened for unexpected events within 7 days, defined as either ICU admission without another indication, or death without treatment limitations. Patients' characteristics and organisational factors were analysed according to refusal status, outcome and delay in ICU admission. RESULTS: Among 2219 enrolled patients, the refusal rate was 10.4%. Refusal was associated with diagnostic groups, treatment limitations, patients' location on a ward, night time and ICU occupancy. Unexpected events occurred in 16 (6.9%) refused patients. A worse outcome was associated with time spent in hospital before refusal, patients' location on a ward, SOFA score and physician's expertise. Delayed ICU admissions were associated with ICU and hospital length of stay. CONCLUSIONS: ICU triage selected safely most patients who would have probably not benefited from the ICU. We identified individual and organisational factors associated with ICU refusal, subsequent ICU admission or death.

Dynamics of disease characteristics and clinical management of critically ill COVID-19 patients over the time course of the pandemic: an analysis of the prospective, international, multicentre RISC-19-ICU registry.

BACKGROUND: It remains elusive how the characteristics, the course of disease, the clinical management and the outcomes of critically ill COVID-19 patients admitted to intensive care units (ICU) worldwide have changed over the course of the pandemic. METHODS: Prospective, observational registry constituted by 90 ICUs across 22 countries worldwide including patients with a laboratory-confirmed, critical presentation of COVID-19 requiring advanced organ support. Hierarchical, generalized linear mixed-effect models accounting for hospital and country variability were employed to analyse the continuous evolution of the studied variables over the pandemic. RESULTS: Four thousand forty-one patients were included from March 2020 to September 2021. Over this period, the age of the admitted patients (62 [95% CI 60-63] years vs 64 [62-66] years, p < 0.001) and the severity of organ dysfunction at ICU admission decreased (Sequential Organ Failure Assessment 8.2 [7.6-9.0] vs 5.8 [5.3-6.4], p < 0.001) and increased, while more female patients (26 [23-29]% vs 41 [35-48]%, p < 0.001) were admitted. The time span between symptom onset and hospitalization as well as ICU admission became longer later in the pandemic (6.7 [6.2-7.2| days vs 9.7 [8.9-10.5] days, p < 0.001). The PaO2/FiO2 at admission was lower (132 [123-141] mmHg vs 101 [91-113] mmHg, p < 0.001) but showed faster improvements over the initial 5 days of ICU stay in late 2021 compared to early 2020 (34 [20-48] mmHg vs 70 [41-100] mmHg, p = 0.05). The number of patients treated with steroids and tocilizumab increased, while the use of therapeutic anticoagulation presented an inverse U-shaped behaviour over the course of the pandemic. The proportion of patients treated with high-flow oxygen (5 [4-7]% vs 20 [14-29], p < 0.001) and non-invasive mechanical ventilation (14 [11-18]% vs 24 [17-33]%, p < 0.001) throughout the pandemic increased concomitant to a decrease in invasive mechanical ventilation (82 [76-86]% vs 74 [64-82]%, p < 0.001). The ICU mortality (23 [19-26]% vs 17 [12-25]%, p < 0.001) and length of stay (14 [13-16] days vs 11 [10-13] days, p < 0.001) decreased over 19 months of the pandemic. CONCLUSION: Characteristics and disease course of critically ill COVID-19 patients have continuously evolved, concomitant to the clinical management, throughout the pandemic leading to a younger, less severely ill ICU population with distinctly different clinical, pulmonary and inflammatory presentations than at the onset of the pandemic.

Critical care staffing ratio and outcome of COVID-19 patients requiring intensive care unit admission during the first pandemic wave: a retrospective analysis across Switzerland from the RISC-19-ICU observational cohort.

STUDY AIM: The surge of admissions due to severe COVID-19 increased the patients-to-critical care staffing ratio within the ICUs. We investigated whether the daily level of staffing was associated with an increased risk of ICU mortality (primary endpoint), length of stay (LOS), mechanical ventilation and the evolution of disease (secondary endpoints). METHODS: We employed a retrospective multicentre analysis of the international Risk Stratification in COVID-19 patients in the ICU (RISC-19-ICU) registry, limited to the period between March 1 and May 31, 2020, and to Switzerland. Hierarchical regression models were used to investigate crude and adjusted effects of the critical care staffing ratio on study endpoints. We adjusted for disease severity and weekly caseload. RESULTS: Among the 38 participating Swiss ICUs, 17 recorded staffing information. The study population included 437 patients and 2,342 daily assessments of patient-to-critical care staffing ratio. Median of daily patient-to-nurse ratio started at 1.0 [IQR 0.5-1.5; calendar week 9] and peaked at 2.4 (IQR 0.4-2.0; calendar week 16), while the median of daily patient-to-physician ratio started at 4.0 (IQR 2.1-5.0; calendar week 9) and peaked at 6.8 (IQR 6.3-7.3; calendar week 19). Neither the patient-to-nurse (adjusted OR 1.28, 95% CI 0.85-1.93; doubling of ratio) nor the patient-to-physician ratio (adjusted OR 1.07, 95% CI 0.87-1.32; doubling of ratio) were associated with ICU mortality. We found no association of daily critical care staffing on the secondary endpoints in adjusted models. CONCLUSION: We found no association of reduced availability of critical care staffing resources in Swiss ICUs with overall ICU length of stay nor mortality. Whether long-term outcome of critically ill patients with COVID-19 have been affected remains to be studied.

Granulomatosis with polyangiitis (Wegener's) complicated by splenic rupture and severe acute respiratory distress syndrome: A case report.

Even in the absence of disease-specific radiological signs of granulomatosis with polyangiitis (GPA), severe intrapulmonary GPA may be present. Rapidly establishing the diagnosis with a confirmatory biopsy is key to initiate lifesaving therapy.

Implications of early respiratory support strategies on disease progression in critical COVID-19: a matched subanalysis of the prospective RISC-19-ICU cohort.

BACKGROUND: Uncertainty about the optimal respiratory support strategies in critically ill COVID-19 patients is widespread. While the risks and benefits of noninvasive techniques versus early invasive mechanical ventilation (IMV) are intensely debated, actual evidence is lacking. We sought to assess the risks and benefits of different respiratory support strategies, employed in intensive care units during the first months of the COVID-19 pandemic on intubation and intensive care unit (ICU) mortality rates. METHODS: Subanalysis of a prospective, multinational registry of critically ill COVID-19 patients. Patients were subclassified into standard oxygen therapy ≥10 L/min (SOT), high-flow oxygen therapy (HFNC), noninvasive positive-pressure ventilation (NIV), and early IMV, according to the respiratory support strategy employed at the day of admission to ICU. Propensity score matching was performed to ensure comparability between groups. RESULTS: Initially, 1421 patients were assessed for possible study inclusion. Of these, 351 patients (85 SOT, 87 HFNC, 87 NIV, and 92 IMV) remained eligible for full analysis after propensity score matching. 55% of patients initially receiving noninvasive respiratory support required IMV. The intubation rate was lower in patients initially ventilated with HFNC and NIV compared to those who received SOT (SOT: 64%, HFNC: 52%, NIV: 49%, p = 0.025). Compared to the other respiratory support strategies, NIV was associated with a higher overall ICU mortality (SOT: 18%, HFNC: 20%, NIV: 37%, IMV: 25%, p = 0.016). CONCLUSION: In this cohort of critically ill patients with COVID-19, a trial of HFNC appeared to be the most balanced initial respiratory support strategy, given the reduced intubation rate and comparable ICU mortality rate. Nonetheless, considering the uncertainty and stress associated with the COVID-19 pandemic, SOT and early IMV represented safe initial respiratory support strategies. The presented findings, in agreement with classic ARDS literature, suggest that NIV should be avoided whenever possible due to the elevated ICU mortality risk.

Characteristics, comorbidities, 30-day outcome and in-hospital mortality of patients hospitalised with COVID-19 in a Swiss area - a retrospective cohort study.

BACKGROUND: Since its first description in December 2019, coronavirus disease 19 (COVID-19) has spread worldwide. There is limited information about presenting characteristics and outcomes of Swiss patients requiring hospitalisation. Furthermore, outcomes 30 days after onset of symptoms and after hospital discharge have not been described. AIMS: To describe the clinical characteristics, outcomes 30 days after onset of symptoms and in-hospital mortality of a cohort of patients hospitalised for COVID-19 in a Swiss area. METHODS: In this retrospective cohort study, we included all inpatients hospitalised with microbiologically confirmed COVID-19 between 1 March and 12 April 2020 in the public hospital network of a Swiss area (Fribourg). Demographic data, comorbidities and outcomes were recorded. Rate of potential hospital-acquired infection, outcomes 30 days after onset of symptoms and in-hospital mortality are reported. RESULTS: One hundred ninety-six patients were included in the study. In our population, 119 (61%) were male and the median age was 70 years. Forty-nine patients (25%) were admitted to the intensive care unit (ICU). The rate of potential hospital-acquired infection was 7%. Overall, 30 days after onset of symptoms 117 patients (60%) had returned home, 23 patients (12%) were in a rehabilitation facility, 18 patients (9%) in a medical ward, 6 patients (3%) in ICU and 32 (16%) patients had died. Among patients who returned home within 30 days, 73 patients (63%) reported persistent symptoms. The overall in-hospital mortality was 17%. CONCLUSION: We report the first cohort of Swiss patients hospitalised with COVID-19. Thirty days after onset of the symptoms, 60% had returned home. Among them, 63% still presented symptoms. Studies with longer follow-up are needed to document long-term outcomes in patients hospitalised with COVID-19.

[Myocardial bridging: a contemporary review]. / Le pont myocardique†: mise au point.

Myocardial bridging, corresponds to an abnormal, usually congenital, anatomical relationship between the myocardium and a coronary vessel. It most commonly affects the left anterior descending coronary artery. Despite technological advances, angiography remains the gold standard diagnostic method with a typical image of systolic compression (milking). Typically benign and asymptomatic, myocardial bridging can exceptionally be responsible for serious life threatening complications. Different therapeutic options may be considered, including pharmacological or interventional treatments. We present a clinical case and a review of the respective literature.

Le pont myocardique correspond à une anomalie coronaire, le plus souvent congénitale, dans sa relation anatomique par rapport au muscle myocardique qui touche plus fréquemment l'artère interventriculaire antérieure. Malgré les progrès techniques, l'angiographie demeure la méthode diagnostique de référence avec une image typique de compression systolique milking. Dans la plupart des cas bénigne et asymptomatique, elle peut néanmoins être responsable de complications sérieuses, voire fatales. Plusieurs alternatives thérapeutiques sont envisageables allant du traitement pharmacologique au traitement interventionnel. Le cas clinique présenté dans cet article nous a permis d'effectuer une revue de la littérature à ce sujet.

[Admission or non admission of patients with cancer to the ICU]. / Admission ou non-admission du patient oncologique aux soins intensifs.

Determining if a critically ill patient with cancer will benefit from medical care in an intensive care unit can be a real challenge. Studies show that anticipating critical situations in oncology and collaboration between oncologists and intensivists diminish mortality and enhance resource use. This article covers some of the facts to consider in order to improve the management of these patients.

La question du projet thérapeutique et de l'admission ou non aux soins intensifs (SI) d'un patient souffrant d'un cancer et se trouvant en situation critique peut être complexe à appréhender. La décision d'un tel transfert est lourde de conséquences pour les patients et leurs familles, ainsi que pour son coût humain et économique. Il est donc primordial d'avoir une réflexion en amont sur le bien-fondé de chaque transfert. Une concertation régulière impliquant le médecin traitant/l'oncologue et le malade/sa famille tout au long de l'évolution de la maladie permet de clarifier les situations susceptibles de conduire à un transfert en SI.

Continuous renal replacement therapy: understanding circuit hemodynamics to improve therapy adequacy.

PURPOSE OF REVIEW: The utilization of continuous renal replacement therapy (CRRT) increases throughout the world. Technological improvements have made its administration easier and safer. However, CRRT remains associated with numerous pitfalls and issues. RECENT FINDINGS: Even if new-generation CRRT devices have built-in safety features, understanding basic concepts remains of primary importance. SUMMARY: CRRT circuits' maximum recommended lifespan (72 h) can often not be achieved. Such early artificial kidney failures are typically related to two processes: circuit clotting and membrane clogging. Although these processes are to some degree inevitable, they are facilitated by poor therapy management. Indeed, the majority of device-triggered alarms are associated with blood pump interruption, which through blood stasis, enhance clotting and clogging. If the underlying issue is not adequately managed, further alarms will rapidly lead to prolonged stasis and complete circuit clotting or clogging making its replacement mandatory. Hence, rapid recognition of issues triggering alarms is of paramount importance. Because most alarms are related to circuit's hemodynamics, a thorough understanding of these concepts is mandatory for the staff in charge of delivering the therapy.This review describes CRRT circuits, measured and calculated pressures and the way their knowledge might improve therapy adequacy.

From sanctioning culture to safety culture: Let's stop making errors on error.

The punitive culture continues to prevail in health care organizations that rely primarily on functional systems hierarchies based on conformity. This type of culture is recognized as a major source of an unacceptable number of medical errors. The safety culture has emerged as an imperative to improve the quality and safety of patient care, but also as a shield against the judgments targeted towards the caregivers (doctor and / or nurse) involved in an undesirable event. The safety culture allows a broader view of the error by analyzing both system failures and staff incompetence. Therefore, it places caregivers in their workplace with mutual interactions and protects them from "second victim" status. It is imperative to have a reflection on the safety culture that constitutes a proof of transparency and openness towards society about the mistake that remains taboo. This attitude will avoid the risk of "judicialization of health".

[The culture of "useful error" in health care establishments: impact of morbidity and mortality conferences (MMCs)]. / Culture de l'erreur dans les etablissements de soins: place des colloques de morbidité-mortalité.

Since the publication of the Institute of Medicine's report, "To Err is Human", in 1999, patient safety has become an economic and political objective. The notion of safety involves willingness and initiation of measures to reduce or eliminate errors leading to preventable adverse events. Morbidity and mortality conferences are useful tool to improve local care management through the discussion of adverse events and medical errors and the conception of alternative approaches. In addition, MMCs have an educational value for the entire medical and nursing staff. The involvement of the head of the department is crucial to achieve a cultural change within the caregivers by developing the concept of "useful error" during MMCs.

Early administration of norepinephrine increases cardiac preload and cardiac output in septic patients with life-threatening hypotension.

INTRODUCTION: We sought to examine the cardiac consequences of early administration of norepinephrine in severely hypotensive sepsis patients hospitalized in a medical intensive care unit of a university hospital. METHODS: We included 105 septic-shock patients who already had received volume resuscitation. All received norepinephrine early because of life-threatening hypotension and the need to achieve a sufficient perfusion pressure rapidly and to maintain adequate flow. We analyzed the changes in transpulmonary thermodilution variables associated with the increase in mean arterial pressure (MAP) induced by norepinephrine when the achieved MAP was ≥65 mm Hg. RESULTS: Norepinephrine significantly increased MAP from 54 ± 8 to 76 ± 9 mm Hg, cardiac index (CI) from 3.2 ± 1.0 to 3.6 ± 1.1 L/min/m2, stroke volume index (SVI) from 34 ± 12 to 39 ± 13 ml/m2, global end-diastolic volume index (GEDVI) from 694 ± 148 to 742 ± 168 ml/m2, and cardiac function index (CFI) from 4.7 ± 1.5 to 5.0 ± 1.6 per min. Beneficial hemodynamic effects on CI, SVI, GEDVI, and CFI were observed in the group of 71 patients with a baseline echocardiographic left ventricular ejection fraction (LVEF) >45%, as well as in the group of 34 patients with a baseline LVEF ≤45%. No change in CI, SVI, GEDVI, or CFI was observed in the 17 patients with baseline LVEF ≤45% for whom values of MAP ≥75 mm Hg were achieved with norepinephrine. CONCLUSIONS: Early administration of norepinephrine aimed at rapidly achieving a sufficient perfusion pressure in severely hypotensive septic-shock patients is able to increase cardiac output through an increase in cardiac preload and cardiac contractility. This effect remained in patients with poor cardiac contractility except when values of MAP ≥75 mm Hg were achieved.

Impact of morbidity and mortality conferences on analysis of mortality and critical events in intensive care practice.

BACKGROUND: Morbidity and mortality conferences are a tool for evaluating care management, but they lack a precise format for practice in intensive care units. OBJECTIVES: To evaluate the feasibility and usefulness of regular morbidity and mortality conferences specific to intensive care units for improving quality of care and patient safety. METHODS: For 1 year, a prospective study was conducted in an 18-bed intensive care unit. Events analyzed included deaths in the unit and 4 adverse events (unexpected cardiac arrest, unplanned extubation, reintubation within 24-48 hours after planned extubation, and readmission to the unit within 48 hours after discharge) considered potentially preventable in optimal intensive care practice. During conferences, events were collectively analyzed with the help of an external auditor to determine their severity, causality, and preventability. RESULTS: During the study period, 260 deaths and 100 adverse events involving 300 patients were analyzed. The adverse events rate was 16.6 per 1000 patient-days. Adverse events occurred more often between noon and 4 pm (P = .001).The conference consensus was that 6.1% of deaths and 36% of adverse events were preventable. Preventable deaths were associated with iatrogenesis (P = .008), human errors (P < .001), and failure of unit management factors or communication (P = .003). Three major recommendations were made concerning standardization of care or prescription and organizational management, and no similar incidents have recurred. CONCLUSION: In addition to their educational value, regular morbidity and mortality conferences formatted for intensive care units are useful for assessing quality of care and patient safety.
