COVID-19 pandemic lockdown effect on neonatal hospital admissions from the community

The lockdowns imposed by countries due to COVID-19 pandemic had enormous impact on healthcare. Our goal is to determine consequences of the COVID-19 pandemic lockdown on neonatal hospitalizations and disease incidence in our hospital.

Observational retrospective study comparing newborns admitted to the neonatal care unit (NCU) from emergency department (ED). Newborns were distributed in two groups according to the date of the lockdown (22/3/2020): pre-lockdown group (12 month before) and post-lockdown group (12 month after). Categorical variables were compared according to chi square test and continuous variables with Mann-Whitney test. A Bonferroni corrected p-value < 0.006 was considered statistically significant. The monthly hospitalization rate between the two groups was analyzed with Generalized Method of Moments - System.

We included 99 patients, 65/99 (65.7%) in the pre-lockdown group and 34/99 (34.3%) in the post-lockdown group. Pre-lockdown group: median age at hospitalization 19 (10-26) days, duration of symptoms 12 (5.5-36) hours. Post-lockdown group: median age at hospitalization 16 (6-24) days, duration of symptoms 14 (6-72) hours. The incidence of contagious disease was higher in the pre-lockdown group: 27/65 (41.5%) versus 3/34 (8.8%) in post-lockdown group (p = 0.001). No statistically significant difference in gestational age, gender, age at hospitalization, duration of symptoms and length of stay.

Lockdown decreased admissions in NCU due to the decrease in contagious infections. The similar duration of symptoms before age at hospitalization in the two groups might indicate that health care accessibility has been maintained.
