Objective: To characterize the clinical features of critically ill COVID-19 patients admitted to COVID-ICU and describe their outcomes. Study Design: Retrospective Observational study. Setting: Dr. Ruth K. M. Pfau Civil Hospital Karachi, Pakistan. Period: May 2020 to September 2021. Methods: The study aimed to investigate the clinical characteristics and outcomes of patients with confirmed or suspected COVID-19 who were admitted to the ICU. Patients in the study period confirmed or suspected COVID-19, admitted to the ICU for more than 24 hours, and committed to full treatment were included this study. Patients with COVID-19 discharged or died within 24 hours of admission were excluded. Results: The most commonly observed symptoms among the patients were shortness of breath (92.5%), fever (91.2%), cough without sputum (39.2%), altered consciousness (11.9%), and muscle aches (8.8%). Acute respiratory distress syndrome (ARDS) was identified as the most prevalent complication among COVID-19 patients, impacting 40.8% of the study population. A significant proportion of COVID-19 patients required mechanical ventilation and cardiac support. Specifically, (41.4%) of the patients required invasive mechanical ventilation, (47.4%) required non-invasive ventilation, and (26.3%) received cardiac support. Laboratory assessment showed that platelet counts varied significantly between survivors and non-survivors, with non-survivors exhibiting lower platelet counts. Gender differences were also observed among COVID-19 patients by age, with males having a higher mean age than females in all age categories, and the difference was statistically significant (p < 0.001) in all age categories except for the 30-44 years age category (p = 0.087). Age-wise recovery and mortality rates were analyzed, and the results showed that among both deceased and recovered patients, the proportion of deceased patients increased with age, while the proportion of recovered patients increased until the age range of 45-59 years for both males and females. The study found that 136 of the patients survived while 275 of the patients succumbed to the disease. Among the survivors, (31.3%) were male, and (36.2%) were female. Conclusion: The study emphasizes the importance of monitoring patients for potential complications and providing them with supportive care. Early detection and management of severe cases of COVID-19 are critical in preventing complications and improving patient outcomes.
