Acute respiratory distress syndrome due to COVID-19. Clinical and prognostic features from a medical Critical Care Unit in Valencia, Spain Síndrome de dificultad respiratoria aguda asociado a la COVID-19. Características clínicas y de pronóstico en una unidad de cuidados intensivos de Valencia, España

Objective Information from critically ill coronavirus disease 2019 (COVID-19) patients is limited and in many cases coming from health systems approaches different from the national public systems existing in most countries in Europe. Besides, patient follow-up remains incomplete in many publications. Our aim is to characterize acute respiratory distress syndrome (ARDS) patients admitted to a medical critical care unit (MCCU) in a referral hospital in Spain. Design Retrospective case series of consecutive ARDS COVID-19 patients admitted and treated in our MCCU. Setting 36-bed MCCU in referral tertiary hospital. Patients and participants SARS-CoV-2 infection confirmed by real-time reverse transcriptase–polymerase chain reaction (RT-PCR) assay of nasal/pharyngeal swabs. Interventions None Main variables of interest Demographic and clinical data were collected, including data on clinical management, respiratory failure, and patient mortality. Results Forty-four ARDS COVID-19 patients were included in the study. Median age was 61.50 (53.25 – 67) years and most of the patients were male (72.7%). Hypertension and dyslipidemia were the most frequent co-morbidities (52.3 and 36.4% respectively). Steroids (1mg/Kg/day) and tocilizumab were administered in almost all patients (95.5%). 77.3% of the patients needed invasive mechanical ventilation for a median of 16 days [11-28]. Prone position ventilation was performed in 33 patients (97%) for a median of 3 sessions [2-5] per patient. Nosocomial infection was diagnosed in 13 patients (29.5%). Tracheostomy was performed in ten patients (29.4%). At study closing all patients had been discharged from the CCU and only two (4.5%) remained in hospital ward. MCCU length of stay was 18 days [10-27]. Mortality at study closing was 20.5% (n 9);26.5% among ventilated patients. Conclusions The seven-week period in which our MCCU was exclusively dedicated to COVID-19 patients has been challenging. Despite the severity of the patients and the high need for invasive mechanical ventilation, mortality was 20.5%.

Electronic consultation (e-consultation) between primary care and the neurology department: One-year experience in a healthcare area in Andalusia, Spain

Introduction: The COVID-19 pandemic has prompted the implementation of telemedicine programmes to facilitate healthcare. In November 2020 we initiated an e-consultation programme between primary care and the neurology department, with asynchronous response, through a platform integrated into the corporate computer system of the Andalusian Public Health System. We present the results of the first year of operation. Methods: We present a descriptive study of the e-consultations received in 2021 from a health area of approximately 300,000 inhabitants aged ≥ 14 years. The reasons for consultation were pre-established: "primary headache” (PH), "new-onset cognitive impairment” (CI), "complications of dementia” (DEM), and "epilepsy” (EPI). We defined inclusion criteria and the clinical information/tests that had to be provided. General practitioners could choose between e-consultation or face-to-face referral. Results: A total of 1,806 e-consultations were received (approximately 6/1,000 population/year). By reasons for consultation: CI 34.3%, PH 32%, DEM 14.4%, EPI 11.7%, unspecified 7.6%. Responses were sent after an average of 2.25 days and were classified as: "refer for in-person consultation” (47.12%), "resolved” (39.98%), "criteria not met” (12.57%), or "follow-up by e-consultation” (0.33%). As expected, a high proportion of face-to-face referrals were required for CI (73.46%);the main value of the system for these patients was to prioritise appointments and select the most appropriate form of care. For the rest of the reasons for consultation, the proportion of "resolved” e-consultations reached 52.61%. Conclusions: Asynchronous e-consultation between primary care and the neurology department is a useful tool in the indicated conditions, offering a rapid, "one-stop” response to a significant proportion of clinical or therapeutic uncertainties, as well as optimising face-to-face appointments. © 2023

High incidence of COVID-19 at nursing homes in Madrid, Spain, despite preventive measures.

OBJECTIVE: To assess the impact of COVID-19 at nine nursing homes in Madrid, Spain, during the first wave of COVID-19 infection and lockdown period when preventive measures were taken to avoid transmission among residents. METHODS: Nine hundred forty-two residents and 846 staff members from nine nursing homes participated in the study (April 18 to June 20, 2020). All participants were tested for SARS-CoV-2 in the nasopharynx by PCR and for IgG antibodies detection. Microbiological status at sampling was defined as active infection (positive PCR ± presence of antibodies), past infection (negative PCR + presence of antibodies), or naïve participants (negative PCR + absence of antibodies). RESULTS: Laboratory results helped classify the residents as having active infection (n=224; 23.8%), past infection (n=462; 49.1%), or being naïve (n=256; 27.1%); staff members were actively infected (n=127; 15.1%), had had a past infection (n=290; 34.2%), or were naïve (n=429; 50.7%). Overall, the percentage of participants with COVID-19 was significantly higher in residents than in staff members (72.8% vs 49.2%; P=0.001). The clinical situation of residents vs staff at sampling was as follows: acute manifestations compatible with COVID-19 (7.3% vs 3.9%; P<0.01) and no manifestations of infection (92.7% vs 96.0%; P<0.01). A large proportion of both asymptomatic and symptomatic residents (69.4% vs 86.6%; P=0.015) had positive PCR results (mostly alongside positive IgG determinations). CONCLUSIONS: COVID-19 affects 75% of the residents in nursing homes in Madrid. The high impact in these settings, despite the strict restrictions adopted during the lockdown, demonstrates the ability of SARS-CoV-2 to cause outbreaks.

Ischaemic stroke and SARS-CoV-2 infection: A causal or incidental association? / Ictus isquémico e infección por SARS-CoV-2, ¿asociación casual o causal?

INTRODUCTION: Ischaemic stroke has been reported in patients with COVID-19, particularly in more severe cases. However, it is unclear to what extent this is linked to systemic inflammation and hypercoagulability secondary to the infection. METHODS: We describe the cases of 4 patients with ischaemic stroke and COVID-19 who were attended at our hospital. Patients are classified according to the likelihood of a causal relationship between the hypercoagulable state and ischaemic stroke. We also conducted a review of studies addressing the possible mechanisms involved in the aetiopathogenesis of ischaemic stroke in these patients. RESULTS: The association between COVID-19 and stroke was probably causal in 2 patients, who presented cortical infarcts and had no relevant arterial or cardioembolic disease, but did show signs of hypercoagulability and systemic inflammation in laboratory analyses. The other 2 patients were of advanced age and presented cardioembolic ischaemic stroke; the association in these patients was probably incidental. CONCLUSIONS: Systemic inflammation and the potential direct action of the virus may cause endothelial dysfunction, resulting in a hypercoagulable state that could be considered a potential cause of ischaemic stroke. However, stroke involves multiple pathophysiological mechanisms; studies with larger samples are therefore needed to confirm our hypothesis. The management protocol for patients with stroke and COVID-19 should include a complete aetiological study, with the appropriate safety precautions always being observed.

[Ethical recommendations for a difficult decision-making in intensive care units due to the exceptional situation of crisis by the COVID-19 pandemia: A rapid review & consensus of experts]. / Recomendaciones éticas para la toma de decisiones difíciles en las unidades de cuidados intensivos ante la situación excepcional de crisis por la pandemia por COVID-19: revisión rápida y consenso de expertos.

In view of the exceptional public health situation caused by the COVID-19 pandemic, a consensus work has been promoted from the ethics group of the Spanish Society of Intensive, Critical Medicine and Coronary Units (SEMICYUC), with the objective of finding some answers from ethics to the crossroads between the increase of people with intensive care needs and the effective availability of means.In a very short period, the medical practice framework has been changed to a 'catastrophe medicine' scenario, with the consequent change in the decision-making parameters. In this context, the allocation of resources or the prioritization of treatment become crucial elements, and it is important to have an ethical reference framework to be able to make the necessary clinical decisions. For this, a process of narrative review of the evidence has been carried out, followed by a unsystematic consensus of experts, which has resulted in both the publication of a position paper and recommendations from SEMICYUC itself, and the consensus between 18 scientific societies and 5 institutes/chairs of bioethics and palliative care of a framework document of reference for general ethical recommendations in this context of crisis.

Colombian consensus for the prevention, diagnosis and treatment of thrombotic conditions in adults with COVID-19: applying GRADE Evidence to Decision (EtD) Frameworks

Introduction: recent studies have reported the occurrence of thrombotic phenomena or coagulopathy in patients with COVID-19. There are divergent positions regarding the prevention, diagnosis, and treatment of these phenomena, and current clinical practice is based solely on deductions by extension from retrospective studies, case series, observational studies, and international guidelines developed prior to the pandemic. Objective: to generate a group of recommendations on the prevention, diagnosis and management of thrombotic complications associated with COVID-19. Methods: a rapid guidance was carried out applying the GRADE Evidence to Decision (EtD) frameworks and an iterative participation system, with statistical and qualitative analysis. Results: 31 clinical recommendations were generated focused on: a) Coagulation tests in symptomatic adults with suspected infection or confirmed SARS CoV-2 infection;b) Thromboprophylaxis in adults diagnosed with COVID-19 (Risk scales, thromboprophylaxis for outpatient, in-hospital management, and duration of thromboprophylaxis after discharge from hospitalization), c) Diagnosis and treatment of thrombotic complications, and d) Management of people with previous indication of anticoagulant agents. Conclusions: recommendations of this consensus guide clinical decision-making regarding the prevention, diagnosis, and treatment of thrombotic phenomena in patients with COVID-19, and represent an agreement that will help decrease the dispersion in clinical practices according to the challenge imposed by the pandemic.
