Challenges and Solutions during the COVID-19 Pandemic: Hospitalization and Performance in Elective Pediatric...

Background and Objectives: This retrospective study aimed to investigate the impact of the COVID-19 pandemic on the most frequently performed elective pediatric surgical procedures and the number of hospitalizations and compare it to the pre-pandemic and post-pandemic periods. Materials and Methods: The subjects were patients under 18 years of age who were regularly admitted for selected elective procedures in a single tertiary center in Croatia from 1 March to 31 August of 2019, 2020, 2021, and 2022. Data were collected from the electronic logs of surgical procedures and hospital admissions, logs of one-day surgeries, patients' medical records, and discharge letters. The primary outcome of this study was to determine the evolution of the number of elective surgical procedures before, during, and after the peak of the COVID-19 pandemic; also, we aimed to confirm and objectify global data and statements about the decrease in the number of hospital admissions and surgical procedures. Secondary outcome measures included the length of hospitalization, the number and types of complications, and readmissions. Results: In 2020, the number of elective procedures decreased by 28.3% and the number of hospitalizations decreased by 36.2%; in 2021, the number of elective procedures decreased by 30.8% and the number of hospitalizations decreased by 14.2% compared to the pre-pandemic period (2019). In 2022, there was a 22.8% increase in elective procedures and a 2.9% decrease in hospitalizations compared to 2019. No statistical difference was found in the rates of complications between the individual years studied in terms of complications (p = 0.869). Conclusions: The number of elective procedures and hospitalizations during the COVID-19 pandemic has decreased significantly compared to the pre-pandemic period. After the healthcare system adapted to the conditions of the pandemic, the number of elective procedures increased significantly despite COVID-19, while the number of hospitalizations remained approximately the same as before the pandemic.
