Abstract
Introduction: The novel Coronavirus disease 19 (COVID-19) affected India, predominantly in two time periods – the first wave from March to December 2020, and the second wave that raged from April to July 2021. Although the time duration of second wave was shorter than the first, the onslaught of the disease was much more severe during the second wave. Objective: To compare the demographic characteristics and clinical outcomes of COVID-19 patients admitted during the first and second pandemic waves. Method: Demographic characteristics, duration of hospitalization, critical unit admission, and mortality data of 137 and 345 COVID-19 positive individuals, from first and second waves respectively, were retrospectively analyzed in a teaching hospital in South India. Descriptive statistics, Independent t test, chi square tests and regression analysis were used for statistical analysis, with significance level prefixed at 5%. Results: Median age of hospitalisation was 46.2 years and 48.39 years during first and second waves respectively, with male preponderance in second wave. There was a statistically significant difference in mean duration of stay (9.04 days v/s 7.53 days), mean Spo2 at admission (98.4% v/s 96.6%), ventilation requirement (1.5% v/s 8.7%), oxygen requirement and ICU care between the two waves.Conclusion: During the second COVID wave, significantly higher hospitalisation rates, intensive care requirements and inpatient mortality was observed. Elevated C Reactive Protein levels, lymphocytopenia, history of diabetes and other co-morbidities were associated with poor outcomes in both waves.
