Background: The COVID-19 pandemic has greatly changed the utilization of ambulatory medical care. Studies indicate that this also includes a decrease in pediatric prevention services., Aim: The aim of the study was to determine how the utilization of pediatric prevention services, in particular screening examinations and immunizations, developed over the course of the first pandemic wave until the end of September 2020 compared with the years 2015 to 2019., Materials and Methods: A data analysis based on nationwide statutory medical claims data from the first quarter of 2015 to the third quarter of 2020 was conducted. All treatments of patients aged 0 to 17 years were included and the quarterly case numbers compared on an annual basis. By considering trends and seasonality, preventive and curative treatment cases were modelled as a time series and compared to their expected values., Results and Discussion: No decreases in the quarterly numbers of screening examinations or immunizations were observed in 2020. In contrast, the number of curative pediatric cases decreased significantly in the second and third quarters of 2020 compared with the same periods of the previous years. Since there was no drop in the number of screening examinations, it should be assumed that the health problems addressed in this framework are detected in a timely manner despite the COVID-19 pandemic. However, since screenings do not cover all age groups, further investigation should be conducted to determine the health consequences of the observed decrease in curative cases., (© 2021.
