ASSESSMENT OF OUTCOME AND RISK FACTORS FOR MORBIDITY AND MORTALITY IN COVID ICU PATIENTS- A RETROSPECTIVE STUDY.

Abstract

Objectives

To determine the morbidity and mortality of patients with severe COVID-19 in the intensive care unit (ICU) in relation to age, gender, co-morbidities, mode of oxygen delivery, and length of stay (LOS).

Methodology

This was a retrospective study of patients admitted to Sri Venkateshwara Medical college hospital COVID ICU between April, 2021 to July 2021. From a common database prepared for COVID-19, we retrieved the relevant data and compared the association of age, sex, comorbidities, mode of oxygen delivery and length of ICU stay with morbidity and mortality in COVID ICU patients. Data was entered in Microsoft excel sheet and analysis done by SPSS version 23.0.

Result

Total of 100 patients were admitted in COVID ICU during the study period. The mean age of study participants were observed as 55.79. Among study participants 86% were more than 40 years of age. Among deceased patients the maximum of 48% accounts between age 41-60 (due to associated co morbidities) and there was significant association found between age and clinical outcome (P value < 0.01). Patients with comorbidities accounted for 76% of mortality showing significant association between comorbidities and clinical outcome. Mortality was significantly higher (100%) for patients on IMV as compared to those on NIV (53%) and there was significant association found between mode of oxygen delivery and clinical outcome (P value 0.005). Patients whose length of hospital stay of >10 days in ICU had higher mortality (100%) and there was significant association found between length of stay and clinical outcome.
