# P-1619. The Impact of mask mandate during COVID-19 pandemic on pediatric hospitalization for acute respiratory illnesses in a community hospital

## TL;DR

A study found that mask mandates during the pandemic reduced pediatric hospitalizations for respiratory illnesses.

## Contribution

This study demonstrates the effectiveness of mask mandates in reducing pediatric hospitalizations for respiratory illnesses during the pandemic.

## Key findings

- Pediatric admissions for respiratory illnesses dropped from 188 to 45 after mask mandates were implemented.
- Length of hospital stay decreased, with fewer patients staying more than 2 days after the mandate.
- Mask mandates were associated with reduced healthcare burden during the pandemic.

## Abstract

During the COVID-19 pandemic, public health measures were implemented to prevent the transmission of the virus. One such measure was the mask mandate which was introduced in New York City in April 2020. Use of masks by parents and family members as well as by children themselves helps prevent the transmission of respiratory illnesses that spread through droplets. The principal objective of this study is to assess whether the implementation of a mask mandate during the COVID-19 pandemic had an impact on the number of pediatric hospitalizations for acute respiratory illnesses.Pre-mask vs Post-mask Comparison of VariablesPatient DemograpghicsPre-mask vs Post-mask AdmissionsThe p-value is < 0.00001.

This study is a retrospective analysis of the electronic medical record (EMR) of all children from birth to twenty years admitted to the pediatric floor or the pediatric intensive care unit (PICU) for acute respiratory illnesses including COVID-19, to our community hospital between October 1, 2019 - March 31, 2020 (pre-pandemic) and October 1, 2020 and March 31, 2021 (after mask mandate during the pandemic). Data was analyzed to explore if there are any associations in the two groups related to age, sex, length of hospital stay, severity of illness based on need for respiratory support, use of antibiotics and steroids. SPSS version 25 was used for statistical analysis.Pre-mask vs Post-mask Length of StayThe p-value is 0.048. The result is significant at p <0 .05

We observed a sharp decline in pediatric admissions for respiratory illnesses from 188 before the mask mandate to 45 after the implementation of the mask mandate (Table 2; p < 0.05). We also noted a decrease in the length of stay, where 80.3% of patients had a hospital stay of more than 2 days before the mask mandate compared to 67% after the mask mandate (Table 3; using chi square test; p< 0.05). Demographics and other variables including respiratory support, antibiotics and steroid use are as shown in Table 1.

After the implementation of the mask mandate during the COVID-19 pandemic, there was a significant decline in pediatric hospitalizations for acute respiratory illnesses. This suggests that wearing masks can be an effective way to prevent the transmission of respiratory illnesses, including COVID-19. This study also highlights the importance of adherence to public health measures to reduce healthcare burden especially during a crisis like the COVID-19 pandemic.
