Background: The COVID-19 has a varied mode of presentation in different regions of the world. This multicentric study was planned to evaluate the survival outcomes in intensive care unit-admitted patients admitted during the third wave of the COVID-19 pandemic on the basis of clinicodemographic profile and vaccination status. Methodology: Data from 299 patients admitted to three tertiary care centers in Western India were collected and analyzed. Based on survival outcomes, all patients were divided into two groups: survivors and nonsurvivors. Univariate analysis of the demographic profile, comorbidities, vaccination status, and disease severity was performed, whereas multivariate analysis was performed to predict independent factors associated with mortality. Results: Among total 299 studied patients, 208 (69.5%) patients survived and 91 (30.4%) did not. The number of elderly patients and patients with comorbidities such as diabetes, tuberculosis, chronic obstructive pulmonary disease, cardiovascular and respiratory diseases, and malignancy were more prevalent among nonsurvivors. Patients who did not receive a single dose of vaccine were higher in the nonsurvivor group (P = 0.037); however, no significant difference in survival outcome was found if patients had received the first or both doses of vaccine. The Acute Physiology and Chronic Health Evaluation II (APACHE II) score at 24 h after admission and Sequential Organ Failure Assessment (SOFA) score at admission were significantly higher in nonsurvivors compared to survivors (P < 0.0001). On multivariate analysis, APACHE II and SOFA scores were found to be independent predictors of outcome. Conclusions: Older age, presence of comorbidities, nonvaccination and higher disease severity scores affected mortality during the third wave of COVID-19.
