Effective multidimensional approach for practical management of the emergency department in a COVID-19 designated children's hospital in east China during the Omicron pandemic: a cross-sectional study.

Abstract

Characterized by rapid transmission but lower severity, the new Omicron wave brought about an acute increase in local corona virus disease 2019 (COVID-19) cases in Shanghai, followed by stricter infection prevention and control strategies. Inevitably, more time was required for emergency consultation and treatment of children with critical illnesses. Therefore, a multidimensional approach was designed to streamline the emergency service and reduce the incidence of nosocomial infection of sever acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the Omicron wave for the emergency department (ED) at the Children's Hospital of Fudan University (CHFU). A multidimensional approach was implemented in the ED to help achieve a balance between the demand for emergency services and pandemic control, consisting of ED layout adjustment; electronic screening (E-screening) measures; standard management processes for patients, medical staff, and goods transfer; reliable disinfection measures; and a surveillance system for infection prevention and control. To evaluate the effect of the management strategy, the data on nosocomial infection cases and occupational exposure episodes among staff in the ED were collected. The demographic and clinical characteristics of level I/II children by the five-level pediatric triage tool and their mean duration of stay in the resuscitation room were collected. There were 12,114 ED visitors from March 1 to May 31 in 2022, among which 53.24% were medical emergencies (6,449/12,114) and 46.76% were surgical emergencies (5,665/12,114). Twenty-nine patients were sent to the buffer zone, four of whom were transferred to the pediatric intensive care unit (PICU) because of the critical situation. Six patients tested positive for COVID-19 after entering ED, including three in the buffer zone and three in the ED clinic, causing a temporary closure of the ED for disinfection. There were no reports on medical care delays, unintended deaths, staff with COVID-19 infection, or occupational exposures to COVID-19. Our findings highlight the effectiveness of the multidimensional approach, which can simultaneously meet the emergency care needs of patients as well as pandemic prevention and control. However, the results were obtained against the proportional decrease in clinic visitors due to the Shanghai lockdown. Dynamic assessment and further optimization may be adopted to cope with the pre-pandemic visit volume.
