Anticoagulation Strategies in Non-Critically Ill Patients with Covid-19.

BACKGROUND: Optimal thromboprophylaxis for hospitalized patients with coronavirus disease 2019 (Covid-19) is uncertain. METHODS: In an open-label, adaptive platform trial, we randomly assigned hospitalized adults with Covid-19 to low-dose low-molecular-weight heparin thromboprophylaxis or intermediate-dose or low-dose plus aspirin. In response to external evidence, the aspirin intervention was discontinued and a therapeutic-dose arm added. The primary end point was death or the requirement for new organ support by day 28, analyzed with a Bayesian logistic model. Enrolment was closed as a result of operational constraints. RESULTS: Between February 2021 and March 2022, 1574 patients were randomly assigned. Among 1526 participants included in the analysis (India, n=1273; Australia and New Zealand, n=138; and Nepal, n=115), the primary outcome occurred in 35 (5.9%) of 596 in low-dose, 25 (4.2%) of 601 in intermediate-dose, 20 (7.2%) of 279 in low-dose plus aspirin, and 7 (14%) of 50 in therapeutic-dose anticoagulation. Compared with low-dose thromboprophylaxis, the median adjusted odds ratio for the primary outcome for intermediate-dose was 0.74 (95% credible interval [CrI], 0.43 to 1.27; posterior probability of effectiveness [adjusted odds ratio<1; Pr], 86%), for low-dose plus aspirin 0.88 (95% CrI, 0.47 to 1.64; Pr, 65%), and for therapeutic-dose anticoagulation 2.22 (95% CrI, 0.77 to 6.20; Pr, 7%). Overall thrombotic and bleeding rates were 0.8% and 0.4%, respectively. There were 10 serious adverse reactions related to anticoagulation strategy, of which nine were grade 1 or 2 across study interventions and one grade 4 episode of retroperitoneal hematoma in a patient receiving intermediate-dose anticoagulation. CONCLUSIONS: In hospitalized non­critically ill adults with Covid-19, compared with low-dose, there was an 86% posterior probability that intermediate-dose, 65% posterior probability that low-dose plus aspirin, and a 7% posterior probability that therapeutic-dose anticoagulation reduced the odds of death or requirement for organ support. No treatment strategy met prespecified stopping criteria before trial closure, precluding definitive conclusions.

Pattern of Tuberculosis, Trend and Outcome of Patients Registered at DOTS Centre of a Tertiary Care Hospital.

BACKGROUND: Tuberculosis is a common respiratory disease imposing significant health burden. Directly observed treatment short course strategy ensures patient compliance in tuberculosis treatment. The aim of this study was to assess pattern of tuberculosis, trend and outcome of patients registered at Directly observed treatment short course centre of Tribhuvan University Teaching Hospital. METHODS: A retrospective observational study was conducted at Tribhuvan University Teaching Hospital. Tuberculosis patients of all age groups registered from July 2017 to June 2020 at Tribhuvan University Teaching Hospital Directly observed treatment short course centre were included. Data entry and analysis was done in SPSS version 20.0. Descriptive statistics was performed and results were interpreted in mean, frequency and percentage. RESULTS: A total of 2790 tuberculosis patients were included for final analysis. There were 1736 (62.2%) males. Mean age of patients was 37.94±20.28 years. Pulmonary tuberculosis was the most common type of tuberculosis seen in 948 (34%) patients. Fifty percent of total tuberculosis cases were confined to thorax. Tubercular pleural effusion and pleurisy (14.6%), central nervous system (13.2%), bone and joint (12.2%) were common forms of extrapulmonary tuberculosis. The mean incident tuberculosis cases registered annually was 697.5±95.63. Nearly half (49.1%) of the patients completed tuberculosis treatment regimen while 43.3% were referred to other Directly observed treatment short course centre as per their convenience. CONCLUSIONS: This study reflects the trend and pattern of tuberculosis epidemiology at tertiary care hospital of Nepal. There is a huge burden of both pulmonary and extrapulmonary tuberculosis at Tribhuvan University Teaching Hospital with slight annual variation in incident tuberculosis cases. Despite implementation of Directly observed treatment short course, the problem of non-compliance persists among the tuberculosis patients.

Prevalence of Functional Limitation in COVID-19 Recovered Patients Using the Post COVID-19 Functional Status Scale.

INTRODUCTION: COVID-19 is an emerging global health pandemic causing tremendous morbidity and mortality worldwide. Chronic symptoms progressing to poor functional status have been reported in a substantial proportion of COVID-19 patients worldwide. This study aimed to determine the prevalence of functional limitation in COVID-19 recovered patients using the post-COVID-19 functional status scale. METHODS: A descriptive cross-sectional study was conducted at Tribhuvan University Teaching Hospital. COVID-19 recovered patients with reverse transcription-polymerase chain reaction negative status were included and assessed using the post-COVID-19 functional status scale. Data entry and analysis was done in Statistical Package for the Social Sciences version 20.0. Descriptive statistics were performed. RESULTS: A total of 106 patients were included for the final analysis. More than half of the patients (56.6%) reported having no functional limitation (grade 0), while the prevalence of some degree of functional limitation was observed in 46 (43.4%) patients (grade 1 to 4). CONCLUSIONS: Some form of functional limitation should be anticipated after COVID-19 infection. Post-COVID-19 functional status scale can be a valuable tool in determining the prevalence of functional limitation in COVID-19 recovered patients in acute health care settings. It can potentially guide in planning rehabilitative measures in post-acute care management of COVID-19 survivors.

Diagnostic Fibreoptic Bronchoscopy at Tribhuvan University Teaching Hospital.

BACKGROUND: Fibreoptic bronchoscopy is one of the most vital procedures performed in health care setting. Globally, several studies have reported findings of fibreoptic bronchoscopy while only few studies have been reported in Nepal. The aim of this study was to perform two year retrospective analysis of diagnostic fibreoptic bronchoscopy at tertiary referral centre. METHODS: A hospital based retrospective observational study was conducted at Tribhuvan University Teaching Hospital, Kathmandu, Nepal. Consecutive bronchoscopy reports from June 2017 to May 2019 were included. Data entry and analysis was done in Microsoft Office Excel 2010. Descriptive statistics was performed to obtain clinico-demographic profile of patients, indications and findings of bronchoscopy. RESULTS: A total of 238 bronchoscopy procedures were analyzed. Mean age of patients was 55.02 years with range from 15 to 84 years. Majority of bronchoscopy were performed in male patients (58%). One hundred and twelve patients (47.05%) had no endobronchial lesion. Endoscopically visible tumor was the most common abnormality seen in 57 (23.9%) patients with highest prevalence in 55-65 years followed by extrinsic compression of bronchial tree seen in 13 (5.5%) patients. Bronchioalveolar lavage for routine examination (n=207) was the most commonly performed procedure during bronchoscopy followed by bronchial biopsy (n=55). CONCLUSIONS: Fibreoptic bronchoscopy is an extremely useful tool for evaluation of tracheobronchial pathology. Baseline bronchoscopic findings from tertiary referral centre in Nepal was obtained in this study.

Pattern of Respiratory Diseases, Morbidities and Outcome in Patients Admitted in Respiratory Ward of a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

INTRODUCTION: Respiratory diseases are a leading cause of morbidity and mortality worldwide imposing a significant global health burden. The admission rate of patients is the indication of the overall workload in the ward. The aim of this study was to find the prevalence of admission of patients in the pulmonology ward among patients visiting the pulmonology department of a tertiary care hospital. METHODS: A descriptive cross-sectional study was conducted at Tribhuvan University Teaching Hospital. Medical records of all patients visiting the pulmonology department and admitted to the pulmonology ward from May 2018 to April 2020 were retrospectively reviewed. Data entry and analysis was done in SPSS version 20.0. Descriptive statistics were performed. RESULTS: A total of 30,480 patients visited the pulmonology department in the two-year study period. Out of them, 1296 (4.25%) patients were admitted to the pulmonology ward. Eleven respiratory diseases were identified as primary causes for admission. Acute exacerbation of chronic obstructive pulmonary disease (44.5%), pneumonia (26.3%), tuberculosis (11%), lung cancer (5%), and bronchiectasis (3.9%) ranked the top five causes for admission. CONCLUSIONS: Respiratory diseases impose a tremendous burden in the health care setting. Acute exacerbation of the chronic obstructive pulmonary disease, pneumonia, and tuberculosis remains an important cause of respiratory admissions in our study.
