RESULTS
As of April 30th, 2021, the EPICO-AEP database had
registered 666 hospitalized patients, including 165/666 (25%) with a
final diagnosis of CAP at discharge. Of the 165 patients, 151 with
pathological chest X-ray (CXR) on admission were selected for the
comparative study. The participants included 91/151 (60%) male
children, with a median age of 8 years (IQR 1–13). A total of 76/151
(50%) children had household contact with a confirmed COVID-19 patient.
For analytical purposes, the patients were distributed according to the
COVID-19 waves. Until the end of April 2021, Spain experienced four
waves (Figure 1): 1st wave, February
27th to May 31st, 2020;
2nd wave, June 1st to November
2nd, 2020; 3rd wave, September
15th to December 15th, 2020;
4th wave, December 15th, 2020 to
April 30th, 2021. The maximum peak of admissions for
CAP was recorded during the first wave: with 83% of cases (126/151).
