Strategies to supplement the number of healthcare workers attending COVID-19 patients had to be implemented. Several institutions used non-respiratory clinicians to work in COVID-19 wards. At Universitas Academic Hospital (UAH), Bloemfontein, South Africa, respiratory technologists were requested to assist with managing the oxygen supportive care of patients with severe COVID-19 and respiratory failure.</p><p><strong>Objectives: </strong>To highlight the contribution that respiratory technologists made in the management of severe COVID-19 pneumonia patients by describing the baseline characteristics and mortality of patients with COVID-19, whose oxygen supportive care was managed primarily by respiratory technologists at UAH.</p><p><strong>Methods: </strong>This was a retrospective study. The investigators extracted data from the hospital files of all adult patients admitted with severe COVID-19 to UAH and where respiratory technologists were involved in their care between 1 January and 31 December 2020.</p><p><strong>Results: </strong>A total of 781 patients were admitted to UAH, of whom 106 fulfilled the inclusion criteria. The majority of the patients were female (n=68; 64.1%), and the median age (interquartile range (IQR)) was 59.5 (51 - 68) years. Hypertension (n=69; 65.1%) and diabetes mellitus (n=39; 36.8%) were the most frequent comorbidities. At the time of admission, the median oxygen saturation was 92% and the median respiratory rate oxygenation (ROX) index was 3.2. The median length of stay was 7 days and the mortality was 41.5%.</p><p><strong>Conclusion: </strong>The clinical characteristics and mortality of patients whose oxygen support was managed by respiratory technologists were similar to those in previously reported studies from resource-limited settings.

Endoscopic lung volume reduction (ELVR) was first proposed by the South African Thoracic Society (SATS) for the treatment of advanced emphysema in 2015. Since the original statement was published, there has been a growing body of evidence that a certain well-defined sub-group of patients with advanced emphysema may benefit from ELVR, to the point where the current Global Initiative for Chronic Obstructive Lung Disease (GOLD) Guidelines and the United Kingdom National Institute for Health and Care Excellence (NICE) advocate the use of endoscopic valves based on level A evidence. Patients aged 40 - 75 years with severe dyspnoea (COPD Assessment Test score ≥10) despite maximal medical therapy and pulmonary rehabilitation, with forced expiratory volume in one second (FEV<sub>1</sub>) 20 - 50%, hyperinflation with residual volume (RV) >175% or RV/total lung capacity (TLC) >55% and a six-minute walking distance (6MWD) of 100 - 450 m (post-rehabilitation) should be referred for evaluation for ELVR, provided no contraindications (e.g. severe pulmonary hypertension) are present. Further evaluation should focus on the extent of parenchymal tissue destruction on high-resolution computed tomography (HRCT) of the lungs and interlobar collateral ventilation (CV) to identify a potential target lobe. Commercially available radiology software packages and/or an endobronchial catheter system can aid in this assessment. The aim of this statement is to provide the South African medical practitioner and healthcare funders with an overview of the practical aspects and current evidence for the judicious use of the valves and other ELVR modalities which may become available in the country.</p>","PeriodicalId":52847,"journal":{"name":"African Journal of Thoracic and Critical Care Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/9a/82/AJTCCM-28-2-249.PMC9315962.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40578970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
