The Coronavirus Disease (COVID-19) pandemic has contributed to a co-occurring psychiatric epidemic. Children and adolescents have been particularly impacted, with disruptions in continuity of learning and healthcare. Psychological stressors such as fear of infection, boredom, decreased socialization, supply shortages, and incomplete information have contributed to low mood, irritability, insomnia, and emotional exhaustion. Our study contributes to this research by quantifying the devastating psychiatric toll that the COVID isolation period and virtual schooling had on the mental health of children. The Loyola University Medical Center (LUMC) Consultation-Liaison Psychiatry Service (CLP) (Maywood, IL) designed a study to identify and analyze data regarding the total number of CLP consult requests, patient presentations to the emergency department (ED), and admissions to the Pediatrics floor and Pediatric Intensive Care Unit (PICU) during the COVID pandemic. IRB approval was obtained for this retrospective chart review study. ED visits and Pediatric floor/PICU admissions of all pediatric patients (6-18 years old), specifically those related to mental health, were identified using ICD-9 diagnostic coding for the dates of March 2019 through February 2022. The total number of admissions and encounter diagnoses were analyzed and compared between 3 pandemic periods: Pre-pandemic phase (March 2019-February 2020), acute pandemic phase: isolation/virtual schooling (March 2020-February 2021), and chronic pandemic phase: post-isolation/virtual schooling (March 2021-February 2022). During the chronic pandemic phase, ED visits and Pediatric floor/PICU admissions of all pediatric patients were identified via manual chart review of existing CLP patient lists. The total number of admissions, along with diagnoses during encounters, were compared between the 3 periods and psychiatric admissions were further subcategorized into intentional drug overdoses. In the pre-pandemic phase, there were 39,304 total encounters for children (6-18 years), with 11,189 ED-only visits, and 3,043 inpatient admissions. In the acute pandemic phase, total encounters fell to 15,779, with 4,631 ED-only visits, and 2,578 inpatient admissions. Pre-pandemic, 0.55% of all pediatric encounters required psychiatry consults compared to 1.32% after the onset of the pandemic. During the pre-pandemic phase, there were 27 PICU admissions for psychiatric-related conditions (i.e. intentional ingestion) or 4.52% of all PICU admissions. During the acute pandemic period, there were 57 PICU admissions for psychiatric-related conditions or 11.19% of all PICU admissions. Specifically, there was a rise in intentional ingestion cases from 25 prior to the pandemic to 44 after the onset of the pandemic. During the chronic pandemic period, there were 43 PICU admissions for psychiatric-related conditions. Of those 43 admissions, 33 were intentional drug overdoses. Total encounters during this phase were comparable to the pre-pandemic phase (39,304 encounters pre-pandemic vs. 32,544 encounters in chronic pandemic phase).At this large academic medical center, the pandemic has had a clear impact on total pediatric encounters, with a rise in the number of PICU admissions for psychiatric-related conditions. Findings from this study can be used to inform public policy and develop guidelines in preparation for future pandemics. Safeguards should be put in place to address the significant effects that social isolation and virtual schooling have on the mental health of children, including but not limited to widespread therapy sessions incorporated into the virtual school day and socially distanced in-person activities when safe.
