Introduction: Coronavirus Disease-2019 (COVID-19) infection can cause a wide range of symptoms, from asymptomatic infection and mild upper respiratory tract disease to severe viral pneumonia with respiratory failure and multiorgan malfunction. Through this study, effort was put forward to know the COVID-19 in terms of clinical characteristics, risk factors and laboratory parameters which in turn may serve as predictors of severe sickness and negative outcomes of COVID-19.
Aim: To study the clinical characteristics, risk factors and laboratory parameters of COVID-19 patients in a part of North-Eastern India, and also to compare these parameters between survivors and non survivors.
Materials and Methods: This retrospective study was conducted in Silchar Medical College and Hospital, Silchar, Assam, India. Study included all patients of COVID-19 diagnosed by Reverse Transcriptase Polymerase Chain Reaction (RTPCR) or Rapid Antigen Test (RAT) admitted from 1st July, 2020 to 31st December, 2020. The data included demographic parameters, presenting symptoms, significant medical, surgical or drug history etc., and laboratory parameters including complete blood count, Random Blood Sugar (RBS), chest X-ray, renal and liver function test, C-reactive protein, Lactate Dehydrogenase (LDH), serum ferritin, troponin I etc. Data were statistically analysed by unpaired t-test for continuous variables and Chi-square test was used for comparing proportions.
Results: Out of a total 2262 study subjects, 2066 (91.34%) were discharged from the hospital after recovery and 196 (8.66%) had expired. The various parameters contributing significantly to mortality were male gender, age >60 years, various co-morbid conditions like diabetes mellitus, hypertension and cardiac illness. The laboratory parameters observed to be significantly associated with mortality were thrombocytopenia, leucocytosis, hyperglycaemia, raised value of lactate dehydrogenase, creatinine, D-dimer, ferritin, C-reactive protein. Radiological findings including ground glass opacities and pleural effusion also were more common in the non survivor group as compared to the survivor group.
Conclusion: More than half of the deceased patients were older than 60 years of age. The prevalence of co-morbidities and mean level of laboratory parameters were significantly high among non survivors as compared to those who recovered.
