Risk Categories

(1) Background: The inflammation or cytokine storm that accompanies COVID-19 marks the prognosis. This study aimed to identify three risk categories based on inflammatory parameters on admission. (2) Methods: Retrospective cohort study of patients diagnosed with COVID-19, collected and followed-up from 1 March to 31 July 2020, from the nationwide Spanish SEMI-COVID-19 Registry. The three categories of low, intermediate, and high risk were determined by taking into consideration the terciles of the total lymphocyte count and the values of C-reactive protein, lactate dehydrogenase, ferritin, and D-dimer taken at the time of admission. (3) Results: A total of 17,122 patients were included in the study. The high-risk group was older (57.9 vs. 64.2 vs. 70.4 years; p < 0.001) and predominantly male (37.5% vs. 46.9% vs. 60.1%; p < 0.001). They had a higher degree of dependence in daily tasks prior to admission (moderate-severe dependency in 10.8% vs. 14.1% vs. 17%; p < 0.001), arterial hypertension (36.9% vs. 45.2% vs. 52.8%; p < 0.001), dyslipidemia (28.4% vs. 37% vs. 40.6%; p < 0.001), diabetes mellitus (11.9% vs. 17.1% vs. 20.5%; p < 0.001), ischemic heart disease (3.7% vs. 6.5% vs. 8.4%; p < 0.001), heart failure (3.4% vs. 5.2% vs. 7.6%; p < 0.001), liver disease (1.1% vs. 3% vs. 3.9%; p = 0.002), chronic renal failure (2.3% vs. 3.6% vs. 6.7%; p < 0.001), cancer (6.5% vs. 7.2% vs. 11.1%; p < 0.001), and chronic obstructive pulmonary disease (5.7% vs. 5.4% vs. 7.1%; p < 0.001). They presented more frequently with fever, dyspnea, and vomiting. These patients more frequently required high flow nasal cannula (3.1% vs. 4.4% vs. 9.7%; p < 0.001), non-invasive mechanical ventilation (0.9% vs. 3% vs. 6.3%; p < 0.001), invasive mechanical ventilation (0.6% vs. 2.7% vs. 8.7%; p < 0.001), and ICU admission (0.9% vs. 3.6% vs. 10.6%; p < 0.001), and had a higher percentage of in-hospital mortality (2.3% vs. 6.2% vs. 23.9%; p < 0.001). The three risk categories proved to be an independent risk factor in multivariate analyses. (4) Conclusion: The present study identifies three risk categories for the requirement of high flow nasal cannula, mechanical ventilation, ICU admission, and in-hospital mortality based on lymphopenia and inflammatory parameters.

Abstract BackgroundPatients with haematological malignancies (HM) face high rates of Intensive Care Unit (ICU) admission and mortality. High flow nasal cannula oxygen (HFNCO) is increasingly used to support HM patients in ward settings, but there is limited evidence on the safety and efficacy of HFNCO in this group. MethodsWe retrospectively reviewed all HM patients receiving ward-based HFNCO, supervised by a critical care outreach service (CCOS), from January 2014 - January 2019. ResultsWe included 130 consecutive patients. Forty-three (33.1%) were weaned off HFNCO without ICU admission. Eighty-seven (66.9%) were admitted to ICU, 20 (23.3%) required non-invasive and 34 (39.5%) invasive mechanical ventilation. ICU and hospital mortality were 42% and 55% respectively. Initial FiO2 <0.4 (OR 0.27, 95% CI 0.09-0.81, p=0.019) and HFNCO use on the ward >1 day (OR 0.16, 95% CI 0.04, 0.59, p=0.006) were associated with reduced likelihood for ICU admission. Invasive ventilation was associated with reduced survival (OR 0.27, 95%CI 0.1-0.7, p=0.007). No significant adverse events were reported.ConclusionHM patients receiving ward-based HFNCO have higher rates of ICU admission, but comparable hospital mortality to those requiring CCOS review without respiratory support. Results should be interpreted cautiously, as the model proposed depends on the existence of CCOS.

AbstractBackground:Preoperative mechanical ventilation is associated with morbidity and mortality following CHD surgery, but prior studies lack a comprehensive analysis of how preoperative respiratory support mode and timing affects outcomes.Methods:We retrospectively collected data on children <18 years of age undergoing cardiac surgery at an academic tertiary care medical centre. Using multivariable regression, we examined the association between modes of preoperative respiratory support (nasal cannula, high-flow nasal cannula/noninvasive ventilation, or invasive mechanical ventilation), escalation of preoperative respiratory support, and invasive mechanical ventilation on the day of surgery for three outcomes: operative mortality, postoperative length of stay, and postoperative complications. We repeated our analysis in a subcohort of neonates.Results:A total of 701 children underwent 800 surgical procedures, and 40% received preoperative respiratory support. Among neonates, 243 patients underwent 253 surgical procedures, and 79% received preoperative respiratory support. In multivariable analysis, all modes of preoperative respiratory support, escalation in preoperative respiratory support, and invasive mechanical ventilation on the day of surgery were associated with increased odds of prolonged length of stay in children and neonates. Children (odds ratio = 3.69, 95% CI 1.2–11.4) and neonates (odds ratio = 8.97, 95% CI 1.31–61.14) on high-flow nasal cannula/noninvasive ventilation had increased odds of operative mortality compared to those on room air.Conclusion:Preoperative respiratory support is associated with prolonged length of stay and mortality following CHD surgery. Knowing how preoperative respiratory support affects outcomes may help guide surgical timing, inform prognostic conversations, and improve risk stratification models.

Abstract Background High flow nasal cannula oxygen (HFNCO) is a relatively new technique used to deliver oxygen in respiratory failure patients. This retrospective study is aiming to assess the role and benefits of using HFNCO compared to non-invasive ventilation (NIV) in management of patients with acute hypoxemic respiratory failure associated with coronavirus disease 2019 (COVID-19). Results A retrospective analysis of the files of 63 patients with COVID-19 and acute hypoxemic respiratory failure admitted to the intensive care unit (ICU), 37 patients received HFNCO as initial therapy, and 26 patients were primarily treated with NIV. There was no significant difference between the 2 groups in terms of baseline characteristics, laboratory tests, arterial blood gases, PaO2/FiO2 values, and vital signs. Re-assessment after 24 h of starting treatment with either HFNCO or NIV showed significant improvement (P<0.01) in the respiratory rate, heart rate, and oxygenation parameters. The magnitude of improvement of the vital signs and oxygenation was not significantly different between patients using HFNCO or NIV. Success rate of HFNCO was 86.4%, endotracheal intubation with invasive mechanical ventilation was required in 10.81% of patients, and mortality rate was 2.7%. Success rate of NIV was 84.6%, endotracheal intubation rate was 11.53%, and mortality rate was 3.8%. No significant difference (P>0.05) between the 2 groups as regards the duration of treatment, rate of endotracheal intubation with invasive mechanical ventilation, and mortality rate. Conclusion High flow nasal cannula oxygen (HFNCO) is effective in the management of acute hypoxemic respiratory failure associated with COVID-19. Its efficacy is similar to NIV, with no difference in the duration of treatment, endotracheal intubation rate, or mortality rate.

Abstract Background: In the midst of the COVID-19 crisis, many frail elderly adults were admitted to our hospital with COVID-19. Some faced severe respiratory failure but were not eligible for invasive mechanical ventilation, due to frailty, functional status, comorbidity or wish of the patient. Our main objective was to investigate whether High-flow nasal cannula (HFNC) treatment on the wards could be an effective alternative treatment for these patients.Methods: A retrospective cohort study amongst COVID-19 adult patients with respiratory failure defined as persisting hypoxemia despite maximum conventional oxygen administration requiring invasive mechanical ventilation in the Intensive Care Unit (ICU) but being treated with HFNC as they were non-eligible due to frailty or wish of the patient.Results: The study included 32 patients between March 9th and May 1st, 2020. The median age was 79.0 years (74.5-83.0) with a median of three comorbidities (3-4) and a median Clinical Frailty Score of 4 out of 9 (3-6). The median SpO2/FiO2 Ratio was 157.5 indicating moderate ARDS. Overall survival rate in the HFNC cohort was 25%. Age (80.5 (78.0-84.3) vs 69.5 (65.5-74.3) p=0.0040) and hypertension (92% vs 25%, p=0.0008) were correlated with mortality.Conclusion: This study suggests that HFNC could be an effective last resort respiratory management strategy for respiratory failure in vulnerable elderly COVID-19 patients who failed on conventional high dose oxygen supply and are not eligible for invasive mechanical ventilation.

Abstract Background: In the midst of the COVID-19 crisis, many frail elderly were admitted to our hospital with COVID-19. We sought a treatment for those who had severe respiratory failure but were not eligible for invasive mechanical ventilation, due to frailty, functional status, comorbidity or wish of the patient. We started with applying High-flow nasal cannula (HFNC) treatment on the wards.Methods: A retrospective cohort study amongst COVID-19 adult patients with respiratory failure defined as persisting hypoxemia despite maximum conventional oxygen administration requiring invasive mechanical ventilation at the Intensive Care Unit (ICU) but being treated with HFNC as they were non-eligible due to frailty or wish of the patient.Results: We included 32 patients between March 9 and May 1, 2020. The median age was 79.0 years (74.5-83.0) with a median of three comorbidities (3-4) and a median Clinical Frailty Score of 4 out of 9 (3-6). The median SPO2/FiO2 Ratio was 157.5 indicating moderate ARDS. Overall survival rate in the HFNC cohort was 25%. Age (80.5 (78.0-84.3) vs 69.5 (65.5-74.3) p=0.0040) and hypertension (92% vs 25%, p=0.0008) were associated with mortality.Conclusion: HFNC can be used as a last resort respiratory management strategy in vulnerable elderly COVID-19 patients in respiratory failure on the wards who failed on conventional high dose oxygen supply and are not eligible for invasive mechanical ventilation.
