ABSTRACT
Telemedicine intensive care unit (Tele-ICU) programs entail command centers staffed with intensivists and critical care nurses who electronically aid with and deliver real-time information to frontline clinicians. The benefits of Tele-ICU are numerous, but the barriers to it often prove insurmountable, accounting for slow adoption in rural and underserved areas where it is needed the most. Remote monitoring can quickly detect patient deterioration, while consultation provided by a remote intensivist expands the capabilities of smaller facilities. The emergence of the coronavirus disease 2019 (COVID-19) pandemic has brought about a sense of urgency, paving the way for the successful adaptation of tele-intensive care concepts. The goal of this scoping review is to map out the available published data regarding healthcare professionals' experiences with implementing Tele-ICU modalities during the COVID-19 pandemic. A primary literature search was performed on PubMed/MEDLINE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases from October 2020 to October 2021. Of the 1,083 records screened, 19 were identified as meeting our inclusion criteria and selected for the final scoping review. Five major areas of Tele-ICU use were identified: teleconsultation, telerounding, telemonitoring, family visitation via teleconference, and changing of hospital infrastructure. A heterogeneous mix of improvised Tele-ICU platforms emerged with a common theme of interdisciplinary and family collaboration in the care of critically ill patients. Existing Tele-ICU systems were expanded, and novel programs were launched. A groundbreaking national network in the U.S. (NETCCN) will standardize the deployment of Tele-ICU and expand its reach. Future research should focus on determining accurate costs and the most reliable forms of remote communication, physician compact agreement licensure, the practical composition of Tele-ICU teams, and standardized access to the electronic health record.
ABSTRACT
The Omicron variant of SARS-CoV-2 achieved worldwide dominance in late 2021. Early work suggests that infections caused by the Omicron variant may be less severe than those caused by the Delta variant. We sought to compare clinical outcomes of infections caused by these two strains, confirmed by whole genome sequencing, over a short period of time, from respiratory samples collected from SARS-CoV-2 positive patients at a large medical center. We found that infections caused by the Omicron variant caused significantly less morbidity, including admission to the hospital and requirement for oxygen supplementation, and significantly less mortality than those caused by the Delta variant.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of an ongoing pandemic, with increasing deaths worldwide. To date, documentation of the histopathological features in fatal cases of the disease caused by SARS-CoV-2 (COVID-19) has been scarce due to sparse autopsy performance and incomplete organ sampling. We aimed to provide a clinicopathological report of severe COVID-19 cases by documenting histopathological changes and evidence of SARS-CoV-2 tissue tropism. METHODS: In this case series, patients with a positive antemortem or post-mortem SARS-CoV-2 result were considered eligible for enrolment. Post-mortem examinations were done on 14 people who died with COVID-19 at the King County Medical Examiner's Office (Seattle, WA, USA) and Snohomish County Medical Examiner's Office (Everett, WA, USA) in negative-pressure isolation suites during February and March, 2020. Clinical and laboratory data were reviewed. Tissue examination was done by light microscopy, immunohistochemistry, electron microscopy, and quantitative RT-PCR. FINDINGS: The median age of our cohort was 73·5 years (range 42-84; IQR 67·5-77·25). All patients had clinically significant comorbidities, the most common being hypertension, chronic kidney disease, obstructive sleep apnoea, and metabolic disease including diabetes and obesity. The major pulmonary finding was diffuse alveolar damage in the acute or organising phases, with five patients showing focal pulmonary microthrombi. Coronavirus-like particles were detected in the respiratory system, kidney, and gastrointestinal tract. Lymphocytic myocarditis was observed in one patient with viral RNA detected in the tissue. INTERPRETATION: The primary pathology observed in our cohort was diffuse alveolar damage, with virus located in the pneumocytes and tracheal epithelium. Microthrombi, where observed, were scarce and endotheliitis was not identified. Although other non-pulmonary organs showed susceptibility to infection, their contribution to the pathogenesis of SARS-CoV-2 infection requires further examination. FUNDING: None.
