Feasibility of USG-Guided Objective Initial Assessment of Pupillary Size and Pupillary Reflexes Versus Clinical Examination in Patients With Altered Mental Status: A Cross-Sectional Study.

BACKGROUND: Pupillary assessment is an important part of the neurological assessment which provides vital information in critically ill patients. However, clinical pupillary assessment is subjective. The ultrasound-guided pupillary examination is objective. There are limited pieces of literature regarding its use in assessing patients with altered mental status. So, we studied the extent of agreement of B-mode ultrasound with clinical examination for assessment of the pupillary size and reflex in patients with altered mental status. OBJECTIVES: The primary objective was to determine the extent of agreement between clinical examination and ultrasound-based examination for assessing pupillary reflex and size in patients with altered mental status in two settings (trauma and non-trauma patients). METHODS: Exactly 200 subjects (158 males, mean [range] age 43.56 [18-92 years]) with no history of partial globe rupture or dementia were included in this cross-sectional study from March 2019 to March 2020. B-mode ultrasound was performed with the subject's eyes closed using a 7-12 MHz linear probe and a standardized light stimulus. ICC score, paired t-test, kappa, Wilcoxon signed-rank test, and Bland-Altman plots were used for statistical analysis. RESULTS: The clinical-USG agreement for pupillary light reflex examination (Pupillary Diameter [PD] at rest, after direct light stimulation [Dstim ] and consensual light stimulation [Cstim ]) was excellent (ICC, 0.93-0.96). The Kappa coefficient (0.74 ± 0.07) showed an agreement of 87.36% between clinical and USG examination for pupillary reflex (reactive or non-reactive). CONCLUSION: USG-guided pupillary examination proves to be a better adjunct to neurological assessment in patients with altered mental status.

Correlation between Transcranial Ultrasound and CT Head to Detect Clinically Significant Conditions in Post-craniectomy Patients Performed by Emergency Physician: A Pilot Study.

Background: The main objective is to detect clinically significant conditions by transcranial ultrasound (TCS) in post-decompressive craniectomy (DC) patients who come to the emergency department. Materials and methods: This was a cross-sectional observational study. We studied 40 post-DC patients. After primary stabilization, TCS was done. Computer tomography of head was done within 2 hours of performing TCS. The correlation between both modalities were assessed by the measurement of lateral ventricle (LV) (Bland-Altman plot), Midline shift and mass lesion. Additionally, normal cerebral anatomy, 3rd and 4th ventricles and external ventricular drainage (EVD) catheter visualization were also done. Results: About 14/40 patients came with non-neurosurgical complaints and 26/40 patients came with neurosurgical complaints. Patients with non-neurosurgical complaints (4/14) had mass lesions and 1/14 had MLS. Patients with neurosurgical complaints (11/26) had mass lesions and about 5 patients had MLS. A good correlation was found between TCS and CT of head in measuring LV right (CT head = 17.4 ± 13.8 mm and TCS = 17.1 ± 14.8 mm. The mean difference (95% CI) = [0.28 (-1.9 to 1.33), ICC 0.93 (0.88-0.96)], Left [CT head = 17.8 ± 14.4 mm and TCS = 17.1 ± 14.2 mm, the mean difference (95% CI) 0.63 (-1.8 to 0.61), ICC 0.96 (0.93-0.98)], MLS [CT head = 6.16 ± 3.59 (n = 7) and TCS = 7.883 ± 4.17 (n = 6)] and mass lesions (kappa 0.84 [0.72-0.89] [95% CI] p-value < 0.001). The agreement between both modalities for detecting mass lesions is 93.75%. Conclusion: Point of care ultrasound (POCUS) is a bedside, easily operable, non-radiation hazard and dynamic imaging tool that can be used for TCS as a supplement to CT head in post-DC patients in emergency as well as in ICU. However, assessment of the ventricular system (pre/post-EVD insertion), monitoring of regression/progression of mass lesion, etc. can be done with TCS. Repeated scans are possible in less time which can decrease the frequency of CT head. How to cite this article: Chouhan R, Sinha TP, Bhoi S, Kumar A, Agrawal D, Nayer J, et al.

Taming the Tiger: Ultra high dose nitroglycerin in managing sympathetic crashing acute pulmonary edema patient.

INTRODUCTION: Sympathetic Crashing Acute Pulmonary Edema (SCAPE) lies on the end of the acute heart failure syndrome spectrum with pulmonary edema in all lung zones. NTG at lower doses (10-20 µg/min) cause preload reduction, and at higher doses (> 100 µg/min) causes after-load reduction by arterial dilatation. The main aim is to decrease the afterload at the earliest to cut the vicious cycle caused by sudden sympathetic upsurge. To our knowledge, this is the highest nitroglycerin dose usage in the literature. CASE: A 60-year-old male with no known prior co-morbidities presented to our Emergency with complaints of acute onset severe shortness of breath, which was also associated with extreme diaphoresis, agitation, anxiety, and palpitations. On Examination, the patient was hypoxic and hypertensive with severe tachypnea and tachycardia. On Auscultation, diffuse bilateral crackles in all areas were heard. Point of care ultrasound showed bilateral B-profile in all lung zones, inferior vena cava was >50% collapsible. We managed the patient with non-invasive ventilation and ultrahigh dose nitroglycerin/ highest ever- 9 mg intravenous bolus with 76 mg infusion. The patient had improved within hours and did not require oxygen. The patient was discharged from the emergency after a few hours of observation. DISCUSSION: SCAPE occurs due to a vicious spiral involving increasing sympathetic outflow, excessive afterload, and worsening heart failure. The central, defining pathophysiological feature of SCAPE is pathologically elevated afterload due to systemic vasoconstriction and hypertension. SCAPE patients may be euvolemic, hypovolemic or hypervolemic. The problem is shift of fluid into the lungs rather than hypervolemia. The emphasis on treating pulmonary edema has shifted from diuretics to vasodilators, especially high-dose nitrates, combined with non-invasive positive pressure ventilation. CONCLUSION: This is the first report describing the safe and effective administration of ultra-high dose bolus/ highest dose ever and prolonged high-dose infusion for SCAPE, along with Non-invasive ventilation, which has prevented mechanical ventilation and mortality. High doses of intravenous NTG are extremely effective and safe for SCAPE patients.

Sensitivity and specificity of waterbath ultrasound technique in comparison to the conventional methods in diagnosing extremity fractures.

INTRODUCTION: Point of care ultrasound (POCUS) has variable diagnostic accuracy in diagnosing fractures. Waterbath technique is a modification of the conventional ultrasound technique which may improve diagnostic accuracy by enhancing image quality. Authors studied the diagnostic accuracy of waterbath technique compared to the final diagnosis based on clinical examination and radiology in the identification of fractures of hand and foot. METHODS: Patients of >18 yrs. age with suspected distal hand and foot fractures presenting to the emergency department of a level 1 trauma center were recruited after informed consent. Unconscious and hemodynamically unstable patients, injuries >72 h old, open fractures, obvious deformities, and old fractures at the affected site were excluded. Cases were subjected to waterbath technique performed by an academic emergency medicine resident and relevant radiographs were ordered and interpreted by an orthopedic specialist. CT/MRI, if done in case of discrepancy, was interpreted by radiologist. The findings of both waterbath technique and radiology were blinded to each other and compared to the final diagnosis made by a cumulative assessment of clinical examination, radiographs, and CT/MRI of the discrepant cases. RESULTS: Waterbath technique identified fractures of hand and foot with sensitivity of 97% (95% CI 90%-100%), specificity 94% (95%CI 81%-99%), PPV 98% (95%CI 91%-99%), NPV 94% (95%CI 79%-98%), LR+ 17.5(95% CI 4.5-67.2), LR- 0.03(95% CI 0.01-0.12) and diagnostic accuracy 96% (95%CI 91%-99%). CONCLUSION: This pilot study has demonstrated the utility of Waterbath technique in the diagnosis of fractures of hand and foot in adults in the ED setting. Future well designed studies are required to explore the potential of this novel technique in both adult and pediatric population.

Assessing the serum chymase level as an early predictor of dengue severity.

We conducted a prospective, observational study to assess the serum chymase level, a mast cell derived protease, as a predictor of dengue severity. NS1-positive non-severe dengue patients of age ≥14 years with duration of fever ≤4 days were included in the study. At the time of admission, the serum sample was taken for chymase estimation. Patients were followed up to four days after they became afebrile to find out the final diagnosis. Total of 338 non-severe dengue patients were recruited (mean age: 29.15 years; male: 66%). On follow-up, 26 patients (7.8%) developed severe dengue. Only chymase level (adjusted odds ratio [aOR]: 1.787; 95% confidence interval [CI]: 1.309-2.440) and platelet count at admission (aOR: 0.981; 95% CI: 0.968-0.993) were able to predict the severity after adjustment for all variables. But, for prediction of severe dengue, the area under receiver's operating curve of chymase was 0.835 (95% CI: 0.765-0.905), which was significantly higher than that of the platelet count at admission (0.760, 95% CI: 0.650-0.870) (p < .001). Patients who developed severe dengue in due course of illness had significantly higher serum chymase level at admission as compared with the rest of the patients. Similar findings were noted across all age-groups. At an optimum cut-off value of 1.35 ng/ml, chymase had a positive likelihood ratio (LR) of 3.5 and a negative LR of 0.15, for predicting severe dengue. This study demonstrated the potential ability of serum chymase levels at admission, as a biomarker for prediction of severe dengue in due course of illness.

Impact of personal protective equipment on the effectiveness of chest compression - A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: To assess the impact of personal protective equipment (PPE) on different aspects of chest compression (CC) during cardiopulmonary resuscitation, we conducted this study. METHODS: This systematic review was performed according to the PRISMA. We searched PubMed, EMBASE and Web of Science from inception to June-6, 2020, limiting to the studies that reported the comparison of the effectiveness of CC in terms of CC rate, CC depth, the proportion of adequate CC rate, the proportion of adequate CC depth or proportion of adequate recoil; in study arms with or without PPE. Risk of bias was assessed by the ROB-2 and ROBINS-I tool. Quantitative data synthesis was done using the generic inverse variance method and the fixed-effects model. RESULTS: Five simulation-based studies were finally included. A Significant decrease in CC rate (SMD: -0.28, 95%CI: -0.47 to -0.10) and CC depth (SMD: -0.26, 95%CI: -0.44 to -0.07) were observed in the PPE arm as compared to the no-PPE arm. The difference in CC rate was more prominently seen in adult CPR than in paediatric CPR. Without PPE, the proportion of adequate CC rate delivered was 0.74, which reduced significantly to 0.60 after use of PPE (p - 0.035). Similarly, the proportion of adequate CC depth was significantly lesser (p - 0.001) in PPE arm (0.55), as compared to that of the no-PPE arm (0.78). CONCLUSION: The use of PPE compromises the quality of CC during CPR significantly, and newer ways to deliver chest compression has to be investigated. This study was prospectively registered in PROSPERO (CRD42020192031).

Lung sonographic findings in COVID-19 patients.

OBJECTIVE: The objective of this study was to describe the lung sonographic findings of COVID-19 patients prospectively and investigate its association with disease severity. METHODS: This study was conducted in an emergency department and included consecutively enrolled laboratory confirmed COVID-19 patients. Lung sonography findings were described in all the included patients and analysed with respect to the clinical severity of the patients. RESULTS: 106 patients were included in the study. Common sonographic findings in COVID-19 patients were pleural line irregularity or shredding (70% of patients), followed by B - profile (59%), pleural line thickening (33%), occasional B - lines (26%), sub-pleural consolidations (35%), deep consolidations (6%), spared areas (13%), confluent B - lines or waterfall sign (14%) and pleural effusion (9%). These findings tended to be present more bilaterally and in lower lung zones. Sonographic characteristics like bilateral lung involvement, B - profile, spared areas and confluent B - lines or waterfall sign were significantly associated (p < 0.01) with clinical severity (more frequent with increasing disease severity). CONCLUSION: The lung sonographic findings of COVID-19 were found more bilaterally and in lower lung zones, and specific findings like B - profile, pleural thickening, spared areas and confluent B - lines or waterfall sign were associated with severe COVID-19.

COVID-19 in health care workers - A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: It is essential to know the proportion of health care workers (HCW) who are COVID 19 positive, as well as the severity and mortality among them. METHODS: This systematic review was performed according to the Preferred Reporting Items for Systematic review and meta-analysis. Databases including PubMed, EMBASE and Web of Science were searched from December-31, 2019 to April-23, 2020. The search was limited to the studies that reported the data on the number of COVID-19 positive healthcare workers, among the COVID-19 positive patients. Case reports, duplicate publications, reviews, and family-based studies were excluded. The methodological quality of studies was assessed by the Appraisal tool for Cross-Sectional Studies (AXIS) tool. RESULTS: In this systematic review and meta-analysis, we pooled eleven studies to investigate the above factors. The overall proportion of HCW who were SARS-CoV-2 positive among all COVID-19 patients was 10.1% (95%CI: 5.3-14.9). This proportion varied according to the country of study i.e. China (7 studies) - 4.2%, 95%CI:2.4-6.0; United States (3 studies) - 17.8%, 95%CI:7.5-28.0; and Italy (1 study) - 9.0%, 95%CI:8.6-9.4. The incidence of severe or critical disease in HCW (9.9%, 95%CI:0.8-18.9) was significantly lower (p < 0.001) than the incidence of severe or critical disease in all COVID-19 positive patients (29.4%, 95%CI:18.6-40.2). Similarly, the mortality among HCW (0.3%, 95%CI:0.2-0.4) was also significantly lower (p < 0.001) as compared to that of all patients (2.3%, 95%CI:2.2-2.4). CONCLUSION: Health care workers who are COVID-19 positive constituted a significant proportion of all COVID-19 patients; but the severity and mortality were lower among them.

Endotracheal Tube Placement Confirmation by Ultrasonography: A Systematic Review and Meta-Analysis of more than 2500 Patients.

BACKGROUND: The integration of point-of-care ultrasound in endotracheal tube placement confirmation has been focus of many recent studies. OBJECTIVES: We sought to determine the diagnostic accuracy of ultrasonography in confirmation of endotracheal intubation compared with standard confirmatory methods. METHODS: We completed an extensive search of PubMed, EMBASE, Cochrane Central, Web of Science, and bibliographies of the selected articles from inception to October 2019. The search was limited to prospective studies conducted in human adults that compared the accuracy of ultrasonography in confirming the endotracheal tube position with a reference standard. The methodologic quality of studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. A bivariate random-effects model summarized diagnostic accuracy statistics. Subgroup analyses by ultrasonographic signs, study location, the operator's specialty, types of transducer, the technique of ultrasound confirmation, and clinical setting (cardiac arrest vs. non-cardiac arrest) were performed. RESULTS: Thirty studies involving 2534 patients were selected for this meta-analysis. The estimated pooled sensitivity and specificity for ultrasonography were 0.982 (95% confidence interval [CI] 0.971-0.988) and 0.957 (95% CI 0.901-0.982), respectively. Subgroup analyses did not reveal significant difference by ultrasonographic sign used, location, the sonographer's specialty, transducer type, or ultrasound technique used. Ultrasound was also found to be a useful adjunct in confirming endotracheal tube position in the subgroup of patients with cardiac arrest, with sensitivity of 0.99 (95% CI 0.98-1.00) and specificity of 0.84 (95% CI 0.67-1.00), respectively. CONCLUSIONS: Ultrasonography is a valuable and reliable adjunct for endotracheal tube confirmation, including during cardiac arrest resuscitation.

Diagnostic accuracy of drooling, reluctance, oropharynx, others, and leukocytosis score as a predictor of mortality and complications following acute corrosive ingestion.

OBJECTIVES: Esophagogastroduodenoscopy is considered the gold standard in assessing the severity of injury to the gastrointestinal tract following corrosive ingestion. Zargar's endoscopic grading of injury helps in prognostication as well as guiding management. Since the major burden of cases lies in resource-limited settings, the availability of endoscopic evaluation is a limiting factor. Hence, it is prudent to develop bedside tools that can be used as screening tools to identify patients at high risk of mortality and complications so that timely referrals and judicious utilization of resources can be made. Literature in this regard is limited and published studies have shown that clinical features fail to predict the severity of injury. We aimed our study to find the role of Drooling, Reluctance, Oropharynx, Others, and Leukocytosis (DROOL) score as a predictor of mortality and complications following acute corrosive ingestion. METHODS: This was a diagnostic accuracy study conducted in the emergency department (ED) of a tertiary care hospital in North India. We screened all cases of acute corrosive ingestion presented to our ED. We collected the data on demographic profile, clinical features, investigations, endoscopy findings, treatment, and DROOL score. We followed patients for up to 12 weeks for outcomes including mortality and complications. RESULTS: We studied 79 patients of acute corrosive ingestion. The median age was 26 years with a female predominance. Nausea, vomiting, and pain abdomen were the common symptoms. The median DROOL score was 4. The majority of our patients had normal to Zargar grade 1 injury to the stomach and esophagus. Out of 79 patients, 27 patients developed some complications. The overall mortality up to 12 weeks was 10%. The receiver operating characteristics (ROC) analysis was performed, and the area under the ROC (AUROC) curve of Zargar classification in predicting overall complications was 0.909 (96% confidence interval [CI]: 0.842-0.975) and it was 0.775 (95% CI: 0.553-1.000) in predicting mortality. The AUROC of DROOL score in predicting overall complications was 0.932 (95% CI: 0.877-0.987) and the AUROC of DROOL score in predicting mortality was 0.864 (95% CI: 0.758-0.970). The ROC analysis showed that a DROOL score ≤4 has a sensitivity of 96.2% and a specificity of 77.8% in predicting overall complications. Similarly, DROOL score ≤5 has a sensitivity of 81.7% and a specificity of 62.5% in predicting the development of mortality. Delong test showed that there was no statistically significant difference in Zargar versus DROOL score in terms of prediction of mortality and overall complications (P > 0.05). CONCLUSION: DROOL score is comparable to Zargar score in identifying patients at high risk of mortality and complications. Hence, DROOL score can be used for risk stratification of patients presenting with corrosive ingestion.

Assessment of Troponin I Levels as a Predictor of Mortality in Acute Decompensated Heart Failure.

BACKGROUND: Acute decompensated heart failure (ADHF) is a highly prevalent diagnosis in the emergency department and is associated with high morbidity and mortality. As mortality remains high even in patients discharged from the emergency, it becomes mandatory to identify markers predictive of mortality in order to guide the disposition of such patients. No literature is available on the prognostic significance of Troponin I in ADHF patients in an emergency setting from an Indian standpoint. OBJECTIVES: This study was aimed at identifying the ability of Troponin I levels at presentation to predict one-month mortality in patients with ADHF. METHODS: The study was conducted in the emergency department of a tertiary healthcare center in north India. Serum cardiac Troponin I (cTnI) levels at presentation were assayed in 101 patients and a one-month follow-up was done. RESULTS: cTnI levels were > 0.02 ng/mL in 51 patients (50.5%). ROC analysis showed an accuracy of 63% in predicting mortality (p < 0.05). Univariate and multivariate analysis showed an OR of 2.58 and 2.74, respectively (p - 0.037 and 0.047, respectively), suggesting cTnI to be a significant predictor of mortality in ADHF. N-terminal proBNP (NT-proBNP) (OR - 2.09; p - 0.229) and left ventricular ejection fraction (OR - 2.01; p - 0.157) were not found to be significant predictors of mortality on regression analysis. CONCLUSION: cTnI levels at presentation are a significant predictor of short-term mortality in ADHF and can be used in an emergency setting to guide treatment, disposition, and follow-up plans of these patients.

Workplace Violence in Healthcare Settings: A Cross-Sectional Survey among Healthcare Workers of North India.

Background: Workplace violence (WPV) is a significant problem in both developed and developing countries, especially among healthcare workers. It has widespread implications for their overall health and well-being. Objective: The study was conducted to assess the problem of violence among doctors and other healthcare workers in healthcare settings. Material and Methods: A cross-sectional survey was conducted using a validated questionnaire from August 21 to September 18, 2021, based on purposive and snowball-sampling techniques for data collection. Appropriate statistical methods were applied to study the association between sociodemographics and characteristics of violence. Results: A total of 601 responses were analyzed. The results showed that approximately 75% of the participants experienced violence in some form at their workplace. These episodes lead to a significant impact on the physical and mental health of these workers. Around one-third of the participants felt uncomfortable reporting these incidents. Some of the most common risk factors and mitigation strategies were also reported by the participants. Conclusion: The findings of this study can be used by the legislators, administrators, and policymakers to develop strategies that can help in mitigating these episodes of violence for the better functioning of the healthcare system.

Phylogeny and evolution of SARS-CoV-2 during Delta and Omicron variant waves in India.

SARS-CoV-2 evolution has continued to generate variants, responsible for new pandemic waves locally and globally. Varying disease presentation and severity has been ascribed to inherent variant characteristics and vaccine immunity. This study analyzed genomic data from 305 whole genome sequences from SARS-CoV-2 patients before and through the third wave in India. Delta variant was reported in patients without comorbidity (97%), while Omicron BA.2 was reported in patients with comorbidity (77%). Tissue adaptation studies brought forth higher propensity of Omicron variants to bronchial tissue than lung, contrary to observation in Delta variants from Delhi. Study of codon usage pattern distinguished the prevalent variants, clustering them separately, Omicron BA.2 isolated in February grouped away from December strains, and all BA.2 after December acquired a new mutation S959P in ORF1b (44.3% of BA.2 in the study) indicating ongoing evolution. Loss of critical spike mutations in Omicron BA.2 and gain of immune evasion mutations including G142D, reported in Delta but absent in BA.1, and S371F instead of S371L in BA.1 could explain very brief period of BA.1 in December 2021, followed by complete replacement by BA.2. Higher propensity of Omicron variants to bronchial tissue, probably ensured increased transmission while Omicron BA.2 became the prevalent variant possibly due to evolutionary trade-off. Virus evolution continues to shape the epidemic and its culmination.Communicated by Ramaswamy H. Sarma.

Isolated vertigo in a young male, HINTS examination and vertebral artery dissection in emergency department - A case report.

Vertigo is not an uncommon presenting symptom in patients presenting to the emergency department (ED) and primary physician's clinic, and around one-tenth of these patients have a central cause, i.e., posterior circulation stroke. HINTS, the acronym for head impulse (HI) test, nystagmus (N), and test of skew (TS), is a neurological examination utilized for differentiating a peripheral cause of vertigo from a sinister central cause. It is a simple, easy-to-do, inexpensive, and less time-consuming test. Here, we present a 27-year young male case without any known comorbidity or trauma, presented to the ED, with complaints of sudden onset isolated vertigo for 2 hours. HINTS examination pointed towards a central cause (normal head impulse test and direction-changing nystagmus). Other neurological and systemic examinations were normal. Non-contrast computed tomography of the brain was normal. Further, computed tomography angiography of head and neck vessels was performed, showing left vertebral artery dissection (VAD). The patient's neurological status deteriorated in the next 8 hours. The patient underwent decompressive craniotomy and got discharged after two weeks. Early performance of the HINTS examination by the primary care physicians and emergency physicians lead to early diagnosis and treatment of this common cause of posterior circulation stroke in young patients. Essential take-home points are the importance of the HINTS test and not to forget VAD as a cause of isolated vertigo without any neck manipulation or trauma.

A cross-sectional evaluation of communication skills and perceived barriers among the resident doctors at a tertiary care center in India.

BACKGROUND: The study was conducted to assess the different components of communication skills and barriers to practicing good communication skills among resident doctors in a health care setting. MATERIALS AND METHODS: A web-based cross-sectional survey was performed, and data were collected using a pre-validated questionnaire with a Cronbach's alpha (0.88). A total of 431 responses were statistically analyzed. Chi-square test was used to associate the socio-demographics and communication skills. Regression analysis was conducted to analyze the association between various communication domains and barriers, which were adjusted for potential confounders such as age and gender. RESULTS: Resident doctors have differential levels of competencies in each domain of communication skills. Around two-thirds of the residents did not practice good communication skills while breaking the bad news and reported poor para-verbal skills. Some of the most common barriers to practicing good communication skills were found to be an infrastructural deficit, lack of time, and long working hours. These barriers significantly affected the communication skills such as para-verbal skills {[-0.32; P < 0.01; C.I (-0.54 to -0.09), [-0.27, P < 0.05, C.I (-0.54 to. 004)], [-0.32, P < 0.01, (0.07-0.56)]}, the ability to break bad news {[-0.42, P < 0.01, (-0.73 to -0.11)], [-0.35, P < 0.05, (-0.75 to -0.35)], [0.48, P < 0.01, (0.12-0.84)]}, and communication with patients/attendants {[0.39, P < 0.01, C.I (-0.71 to -0.06)], [-0.88, P < 0.001, C.I (-1.2 to -0.48)], [-0.88, P < 0.001, C.I (-1.2 to -0.48)]} after adjustment for confounding such as age and gender. CONCLUSION: There is a scope for improvement in practicing good communication skills with patients, among the residents doctors in India. Structured modules for training and evaluation should be implemented in the medical curriculum.

Clinical Determinants of Severe COVID-19 Disease - A Systematic Review and Meta-Analysis.

BACKGROUND: A systematic review and meta-analysis of available studies was performed to investigate the clinical characteristics that can predict COVID-19 disease severity. MATERIALS AND METHODS: Databases including PubMed, Embase, and Web of Science were searched from December 31, 2019, to May 24, 2020. Random-effects meta-analysis was used for summarizing the Pooled odds ratio (pOR) of individual clinical characteristics to describe their association with severe COVID-19 disease. RESULTS: A total of 3895 articles were identified, and finally, 22 studies comprising 4380 patients were included. Severe disease was more common in males than females (pOR: 1.36, 95% confidence interval [CI]: 1.08-1.70). Clinical features that were associated with significantly higher odds of severe disease were abdominal pain (pOR: 6.58, 95% CI: 1.56-27.67), breathlessness (pOR: 3.94, 95% CI: 2.55-6.07), and hemoptysis (pOR: 3.35, 95% CI: 1.05-10.74). pOR was highest for chronic obstructive pulmonary disease (pOR: 2.92, 95% CI: 1.70-5.02), followed by obesity (pOR: 2.84, 95% CI: 1.19-6.77), malignancy (pOR: 2.38, 95% CI: 1.25-4.52), diabetes (pOR: 2.29, 95% CI: 1.56-3.39), hypertension (pOR: 1.72, 95% CI: 1.23-2.42), cardiovascular disease (pOR: 1.61, 95% CI: 1.31-1.98) and chronic kidney disease (pOR: 1.46, 95% CI: 1.06-2.02), for predicting severe COVID-19. CONCLUSION: Our analysis describes the association of specific symptoms and comorbidities with severe COVID-19 disease. Knowledge of these clinical determinants will assist the clinicians in the risk-stratification of these patients for better triage and clinical management.

Predictors of mortality and the need of mechanical ventilation in confirmed COVID-19 patients presenting to the emergency department in North India.

BACKGROUND AND OBJECTIVES: As the number of COVID-19 cases keeps on rising, a better awareness of the nature and severity of the disease will aid in clinical decision-making and management. Hence, this study was conducted to find the predictors of mortality and the need for mechanical ventilation in COVID-19 patients. METHODS: This was a single centre, prospective observational study conducted in a tertiary care centre in north India. We included patients with influenza like illness who tested positive for COVID-19. Information regarding patient demography, symptoms, and vital signs on presentation, laboratory values, chest imaging findings, and disease severity was collected by the emergency physician. QSOFA score and National early warning score (NEWS) score were calculated using initial vital signs. Each patient was followed up till discharge or death. RESULTS: We included 116 COVID-19 patients with 33 patients having mild, 46 patients with severe and 37 patients with critical disease. The median age of our patients was 47 years (39-59) with 63% males. About 58% of patients had at least one comorbidity and shortness of breath was the most common presenting feature. The patients with severe and critical disease had a significantly higher respiratory rate and heart rate as compared to mild disease (p < 0.05). SpO2 of those with critical disease was significantly lower as compared to those with mild disease. Mechanical ventilation was required in around 36% of patients which included 67% of patients with critical disease. The overall mortality was 51% with 90% among critical disease. Lower SpO2 and GCS were the only parameters that showed a significant association with mortality and need for mechanical ventilation. The receiver operating characteristics analysis showed NEWS score as a better predictor of mortality and need for mechanical ventilation as compared to qSOFA score. CONCLUSION: NEWS and qSOFA scores are useful tools in predicting fatal outcomes in COVID patients with NEWS score being a better score than qSOFA.

Novel coronavirus: A capsule review for primary care and acute care physicians.

Novel coronavirus (nCoV) is a new emerging infectious agent causing coronavirus disease 2019 (COVID-19). Since the reporting of early cases of COVID-19 from China on December 29, 2019 till March 15, 2020, it has affected 1,42,539 humans in 135 countries, including 82 cases in India. As it is a difficult task for first-contact physicians, i.e. primary care and acute care physicians, to comprehend the fast-growing knowledge about nCoV and apply for prevention and care of suspected cases of COVID-19, we have tried to provide an updated capsule review of nCoV infection and management of COVID-19. It includes the evidence-based information on epidemiological determinants (agent, host, and environment) of the disease, its clinical features, clinical and laboratory diagnosis, basic infection prevention and control measures, and clinical management of COVID-19 cases. This review also includes the succinct summary of World Health Organization and Center for Diseases Control and Prevention interim guidelines (as of March 15, 2020) on nCoV.
