Epidemiological trend and clinical profile of COVID-19 patients: Experience from a designated COVID-19 center in Delhi.

Objective: To study the epidemiological characteristics of the pandemic by describing the clinical profile of the COVID-19 patients presenting to a super specialty hospital.

Methods: This was a descriptive study using medical records of patients who tested positive for SARS-CoV-2 RNA using reverse transcription-polymerase chain reaction between 17 March and 15 January 2021 while maintaining confidentiality. The clinical and demographic data of all the patients were entered in a Microsoft Excel and statistical analysis was done using SPSS 21 software. Regression analysis was performed and a value < 0.05 was considered to be statistically significant.

Results: A total of 3534 patients were enrolled in this study aged 9-96 years. Among patients with symptoms, fever and cough were the most common presenting symptoms, while 5.6% of the patients were asymptomatic. Hypertension was the most common comorbidity (37%), while no comorbidities were present in 43.0% of the participants and this was statistically significant for age ( = 0.000). Among patient outcomes, >50% of patients were in home isolation, while 11% of patients had a fatal outcome. Elder age group had a higher proportion of expiry among outcomes ( <= 0.001). Most patients had a hospital stay of 9-11 days. A total of 63 health workers were included with male: female ratio being 3.5:1.

Conclusion: Our study reflects that majority of the positive cases that presented to the hospital had mild/moderate symptoms. We believe that appropriate triaging of patients followed by early institution of medicine and good critical care services may help to control this epidemic.
