Clinical characteristics, risk factors and outcomes in patients with severe COVID-19 registered in the International Severe Acute Respiratory and Emerging Infection Consortium WHO clinical characterisation protocol: a prospective, multinational, multicentre, observational study

Due to the large number of patients with severe coronavirus disease 2019 (COVID-19), many were treated outside the traditional walls of the intensive care unit (ICU), and in many cases, by personnel who were not trained in critical care. The clinical characteristics and the relative impact of caring for severe COVID-19 patients outside the ICU is unknown. This was a multinational, multicentre, prospective cohort study embedded in the International Severe Acute Respiratory and Emerging Infection Consortium World Health Organization COVID-19 platform. Severe COVID-19 patients were identified as those admitted to an ICU and/or those treated with one of the following treatments: invasive or noninvasive mechanical ventilation, high-flow nasal cannula, inotropes or vasopressors. A logistic generalised additive model was used to compare clinical outcomes among patients admitted or not to the ICU. A total of 40 440 patients from 43 countries and six continents were included in this analysis. Severe COVID-19 patients were frequently male (62.9%), older adults (median (interquartile range (IQR), 67 (55-78) years), and with at least one comorbidity (63.2%). The overall median (IQR) length of hospital stay was 10 (5-19) days and was longer in patients admitted to an ICU than in those who were cared for outside the ICU (12 (6-23) days versus 8 (4-15) days, p<0.0001). The 28-day fatality ratio was lower in ICU-admitted patients (30.7% (5797 out of 18 831) versus 39.0% (7532 out of 19 295), p<0.0001). Patients admitted to an ICU had a significantly lower probability of death than those who were not (adjusted OR 0.70, 95% CI 0.65-0.75; p<0.0001). Patients with severe COVID-19 admitted to an ICU had significantly lower 28-day fatality ratio than those cared for outside an ICU

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P &lt; 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

Pre-closure parathyroid hormone assay in predicting post-operative hypocalcemia

Background:Transient asymptomatic hypocalcaemia occurs in most patients undergoing thyroidectomy. Symptom occurrence is variable and depends on the rate and decrement of the drop in ionized calcium. The objective was to find the sensitivity and specificity of pre-closure PTH in predicting post-operative hypocalcaemia.  Methods:This is a case control study done in department of surgery medical college Thiruvananthapuram. Study was designed as per the STARD guidelines. 40 patients who have undergone total thyroidectomy, near total thyroidectomy and completion thyroidectomy during one year study period with post-operative hypocalcemia and  pre closure PTH value assayed were selected and compared with  100 patients without post-operative hypocalcemia The data collected were analyzed and sensitivity and specificity of parathyroid hormones in predicting hypocalcaemia was calculated and ROC curve plotted.Results:The sensitivity we found out was that pre-closure PTH assay in predicting hypocalcemia is 100% and specificity 96%. After analyzing the ROC curve we found out that if the lower value of pre-closure PTH is taken as 9.05 pg/ml the test has 100% sensitivity and specificity.Conclusion:Pre closure PTH assay is an excellent investigation to predict post- operative hypocalcaemia in patients undergoing thyroidectomy.

State of Personal Protective Equipment Practice in Indian Intensive Care Units amidst COVID-19 Pandemic: A Nationwide Survey.

Background: Optimal personal protective equipment (PPE) preparedness is key to minimize healthcare workers (HCW) infection with COVID-19. This two-phase survey evaluated PPE preparedness (adherence to Ministry of Health India (MoH) PPE-recommendations; HCW-training; PPE-inventory; PPE-breach management) in Indian intensive care units (ICU). Materials and methods: The phase 1 survey was distributed electronically to intensivists from 481 Indian hospitals between March 25, 2020, and April 06, 2020, as part of a multinational survey. Phase 2 was repeated in 320 Indian hospitals between April 20, 2020, and April 30, 2020. Results: Response rate was 25% from 22 states. PPE practice varied between states and between private, government, and medical colleges. Between phase 1 and phase 2, all aspects of PPE training improved: donning/doffing 43% vs 66%, respectively; p value <0.01); safe waste disposal practices (38% vs 52%; p value = 0.09); intubation training (18% vs 31%; p value = 0.05); and transport (18% vs 31%; p value = 0.05). Perception of confidence for adequate PPE-training improved from 39 to 53% (p value = 0.26). In all, 47 to 60% ICUs adhered to MoH recommendations. Wearing N95-masks at all times increased from 47 to 60% (p value = 0.89). Very few ICUs provided quantitative/qualitative N95 masks fit testing (12% vs 29%; p value <0.01). Low-cost practices like "buddy-system" for donning-doffing (27% vs 44%; p value = 0.02) and showering after PPE breach (10% vs 8%; p value = 0.63) were underutilized. There was reluctance to PPE reuse. In all, 71% were unaware/diffident about PPE inventory. Conclusion: Despite interstate variability, most ICUs conformed to MoH recommendations. This survey conducted during initial pandemic phase demonstrated improved PPE preparedness uniformly across India with scope for further improvement. We suggest implementation of quality improvement measures to improve pandemic preparedness and minimize HCW infection rates, focused on regular PPE training, buddy system, and PPE-breach management
