Evaluation of invasive ventilation rate and comorbidities, clinical signs and lab findings among COVID-19 patients

Abstract

The severity of COVID-19 has been to be associated with comorbidities. It is defined as the presentation of severe respiratory dysfunction or failure, leading to the need for ventilation and mortality. The aim of this study is the evaluate the factors predicting the rate of invasive ventilation among these patients.This retrospective study involved 317 COVID-19 patients referred to (XXX) Hospital in Qom, Iran. The following data were obtained for all the patients: demographic parameters, comorbidities, need for mechanical ventilation, signs and symptoms and lab findings.The results from the demographic data of the study indicated that the need for mechanical ventilation is significantly associated with advanced age, p = 0.001. Additionally, hypertension, leukopenia and blood urea nitrogen to creatinine ratio p = 0.008. p = 0.042 and p < 0.001, respectively, are significantly associated with an increased need for mechanical ventilation. Malignancy, diabetes, asthma, chronic obstructive pulmonary disease, headache, fever, platelet count, prothrombin time, c-reactive protein, erythrocyte sedimentation rate and creatinine phosphatase were not significantly different in the two groups, p > 0.05.Prediction of the extent of severity among COVID-19 patients using clinical parameters and comorbidities prepare medical practitioners and health care centres to take immediate measurements and reduce the burden of the scarcity of health supplies and care.
