Value of standard echocardiography at the bedside for COVID-19 patients in intensive care units: a Japanese single-center analysis.

ABSTRACT:

Purpose

In the era of COVID-19, those special settings or indications for which standard transthoracic echocardiography (TTE) can safely produce benefits or advantages over minimized ultrasound imaging procedures need to be identified. Thus, the purpose of this study was to conduct a retrospective analysis with offline comprehensive conventional measurement of bilateral heart function and develop an appropriate prognostic model for in-hospital death.

Methods

We performed a retrospective analysis of 37 consecutive patients with COVID-19, confirmed by real-time reverse-transcriptase polymerase chain reaction assay, who had undergone clinically indicated standard two-dimensional echocardiographic studies in intensive care wards. Offline comprehensive measurement was also performed. We further integrated the echocardiographic findings as paired evidence of vital organ involvement (possible respiratory distress assessed using right ventricular functional parameters, possible myocardial injury assessed using increased wall thickness, effusion or asynergy) and circulatory failure (suspected low flow status assessed using stroke volume index, suspected congestion assessed using elevated right or left atrial pressure). We evaluated its value for in-hospital death along with other echocardiographic findings.

Results

The most common features included a normal-sized left atrium and left ventricle with preserved left ventricular ejection fraction, despite deteriorated left ventricular flow volume. Less frequent findings, such as abnormalities in the right heart and left ventricular abnormalities suggesting myocarditis, were observed. Although the single echocardiographic parameters failed to show predictive values for in-hospital death, integration of the echocardiographic findings suggested predictive value (p = 0.04, odds ratio: 12.28).

Conclusion

Standard TTE at the bedside with offline comprehensive conventional measurement may provide prognostic information that is valuable for the management of patients with COVID-19.

Project description:Objective: To describe cardiovascular pharmacological support in infants born at <34 weeks' gestation within the first postnatal week in Chinese neonatal intensive care units (NICUs). Design: A secondary analysis of data from a multicenter randomized controlled study (REIN-EPIQ). A questionnaire regarding cardiovascular support practices was also completed by all participating NICUs. Setting: Twenty-five tertiary hospitals from 19 provinces in China. Patients: All infants born at <34 weeks' gestation and admitted to participating NICUs within the first postnatal week from May 2015 to April 2018 were included. Infants who were discharged against medical advice were excluded. Measures and Main Results: Among the 26,212 preterm infants <34 weeks, 16.1% received cardiovascular pharmacological support. The use rates increased with decreasing gestational age and birth weight, with 32.5% among infants <28 weeks and 35.9% among infants <1,000 g. Cardiovascular pharmacological support was independently associated with higher risks of death (aOR 2.8; 95% CI 2.4-3.3), severe intraventricular hemorrhage (IVH) (aOR 2.1; 95% CI 1.8-2.5) and bronchopulmonary dysplasia (BPD) (aOR 2.2; 95% CI 2.0-2.5). Overall 63.1% courses of cardiovascular pharmacological support were >3 days. Prolonged cardiovascular pharmacological support (>3 days) was independently associated with lower rates of survival without morbidity in very-low-birth-weight infants, compared with infants with shorter durations. Dopamine was the most commonly used cardiovascular agent. The cardiovascular pharmacological support rates varied from 1.9 to 65.8% among the participating NICUs. Conclusions: The rate of cardiovascular pharmacological support within the first postnatal week was high with prolonged durations in Chinese NICUs. Marked variation in cardiovascular support existed among participating NICUs. Cardiovascular pharmacological support during the early postnatal period, especially prolonged, may be associated with adverse neonatal outcomes. Clinical Trial Registration: The original trial was registered as "Reduction of Infection in Neonatal Intensive Care Units using the Evidence-based Practice for Improving Quality" (ID: NCT02600195) on clinicaltrials.gov. https://clinicaltrials.gov/ct2/show/NCT02600195?term=NCT02600195&draw=2&rank=1.

Project description:Patients discharged from the ICU post-COVID-19 pneumonitis may experience long-term morbidity related to their critical illness, the treatment for this and the ICU environment. The aim of this study was to characterize the cognitive, psychologic, and physical consequences of COVID-19 in patients admitted to the ICU and discharged alive.DesignProspective cohort study.SettingPost-intensive care syndrome (PICS) follow-up clinic at Tallaght University Hospital, a tertiary referral center with a 16-bed mixed medical-surgical ICU, including critical care physicians, a psychologist, a physiotherapist, and a research nurse.PatientsPatients who had been admitted to the ICU in our tertiary referral center with COVID-19 pneumonitis 6 months earlier.InterventionsNone.Measurements and main resultsA total of 22 patients attended the 6-month PICS follow-up clinic following admission to ICU with COVID-19 pneumonitis. Mean grip strength was low at the 6-month follow-up at 24.1 pounds (sd 9.8) with a minimally active median metabolic equivalent (MET) of 970 METs/wk (interquartile range, 0-7,794 METs/wk). Only 59% of patients were independent with regard to their activities of daily living. Eight of 14 patients (57%) had returned to work by 6 months post-ICU discharge. Their mean Intensive Care Psychological Assessment Tool (IPAT) score was 6.6 (sd 4.6) with a Post-Traumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders-5th Edition (PCL-5) score of 21.1 (sd 17.5) and a mean Montreal Cognitive Assessment (MoCA) score of 24 (sd 8.4); suggestive of mild cognitive impairment. In a multivariable regression model, only Acute Physiology and Chronic Health Evaluation II score was significantly independently associated with MoCA score as a cognitive PICS outcome (beta-coefficient, -1.6; se, 0.6; p = 0.04). None of the predictor variables were significantly independently associated with IPAT and PCL-5 as psychologic outcomes, nor with International Physical Activity Questionnaire-Short Form as a physical PICS outcome.ConclusionsIn this single-center prospective cohort study, we found that patients have a high burden of physical and psychologic impairment at 6 months following ICU discharge post-COVID-19 pneumonitis; in many cases requiring specialist referrals for long-term input. We advocate for increased resources for this much needed follow-up multidisciplinary intervention for an ever-growing population of patients.
