Introduction: It is essential to understand the long-term consequences of COVID-19 in order to improve care of patients and lessen the burden on health care system. This study aimed to look at the clinical and demogaphic characteristics of COVID-19 patients admitted to the hospital and their longterm outcomes after dischage.

Methodology: Hospitalized COVID-19 at a tertiary care hospital between June 2020 and September 2021 were included in this retrospective cohort study. A phone interview was done between November 1 and 30th, 2022 and Medical records were retrieved.

Results: The study included 1087 COVID-19 patients admitted to the hospital, with a mean age of 53.8(SD 15.3) years. Majority were male (n= 638, 68.7%), and 39.5% (n=430) had various comorbidities, with hypertension being the most common (29.7%, n=323), followed by DM (24.4%, n=265). The median length of hospital stay was 5 days, and 5.8% (n-56) required Invasive Mechanical Ventilation. In-hospital mortality was 24.7% (n=268). The remaining 75.3% (n=819) were followed for a median of 609 days (533-850). At the median follow-up time, the mortality rate was 11.5% (n=94), with a higher mortality rate observed in patients over 60 years of age (43%, n= 40). The incidence of respiratory complications was 32.1% (263), with 20.3% (n=166) requiring oxygen therapy at the median follow-up time. Cardiovascular complications occurred in 14.8% (n=122) of patients, while 10% (82) had neurological complications and 20.1% (165) developed new-onset diabetes

Conclusion:

The high death rate and frequent complications found in this study emphasize the necessity of continuing to monitor and manage COVID-19 patients beyond hospital discharge.
