Comparative Study of Physiological and Haematological Parameters among Mild and Severe COVID-19 Patients Admitted in Tertiary Care Hospital of Pune District, India

Background: The COVID-19 pandemic has put global health at stake by creating havoc all over the world, due to which the world, as well as health agencies, are experiencing the greatest challenges. This disease is a health emergency due to its high level of infectiousness and the non-availability of any specific treatment [1].

Objectives: To determine and compare the significance of physiological and haematological parameters in the diagnosis of COVID 19 infection and compare the association of physiological and haematological parameters among mild and severe COVID-19 patients.

Methodology: The present comparative, observational study was carried out in a designated tertiary care hospital, where admission of COVID19 patients in Pune district, India. Various parameters like age, height, weight, BMI, various physiological variables, haematological parameters, and CRP levels were assessed among 202 Mild and 50 severe COVID 19 diagnosed patients on day one of the hospital's stays.

Results: Pearson’s correlation coefficient showed a significant correlation among physiological and haematological variables compared to both groups, especially physiological parameters like SBP and DBP. The results showed that TLC, CRP, NLR, PLR, among COVID 19 patients cans work as important biomarkers to understand the disease prognosis.

Conclusion: Study of physiological and haematological parameters and their interrelation will help in understanding the impact of COVID 19 infection on the reactive inflammatory responses and help in understanding the prognosis of the disease among mild and severe patients.
