ABSTRACT
Background The COVID-19 pandemic has resurfaced in India in the form of a hard-hitting second wave. This study aims to compare the clinical profile of the first wave (April-June 2020) and the second wave (March-May 2021) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a single tertiary care center of India. This will help prioritize the target population group and management strategies in the upcoming third wave if any. Methods In this retrospective observational study, we examined the demographic profile, symptoms at presentation, the severity of illness, baseline investigations, treatments received, underlying comorbidities, and outcomes of the COVID-19 patients belonging to the first (W1) and the second wave (W2) of the pandemic in India. Findings Among 106 patients in W1 and 104 patients in W2, the age group affected most was 37.1 (SD=16.9) years compared with 50.5 (SD=17.7) years respectively. The baseline oxygen saturation is lower in W2, being 84.0 (13.4) % compared with 91.9 (7.4) % in W1. 70.2 % of the cases belonged to the severe category in W2 compared to 37.5% in W1. W2 patients demonstrated higher transaminase levels [SGOT, 108.3 (99.3) v/s 54.6 (69.3); SGPT, 97.6 (82.3) v/s 58.7 (69.7)] with respect to W1. Similarly, the CT severity score for W2 [29.5 (6.7)] was higher than W1 [23.2 (11.5)][All P<0.05]. The proportion of patients requiring oxygen (81.8% v/s 11.2%), high flow nasal cannula (11.4% v/s 5.6%), non-invasive ventilation (41.2% v/s 1.5%), invasive ventilation (24.5% v/s 0.9%), as well as ICU/HDU admissions (56.4% v/s 12.0%) was higher for W2 as compared with W1. The measured case fatality rate varies from 29% for W2 to 9.6% for W1. Interpretation Higher age, oxygen requirement, ventilator requirement, ICU admission, and organ impairment are more prevalent in the admitted COVID-19 cases during the second wave that has hit India compared to the first wave and associated with more fatalities. Strategy for another wave should be planned accordingly.
