About
During the Covid-19 pandemic, admission patterns for infections other than Covid-19 have changed dramatically among children worldwide.
Particularly admissions due to respiratory infections and later invasive streptococcal infections have been well documented.
However, few studies have compared rates af gastro-intestinal infections during the pandemic with the previous years.
This study aims to compare the number and characteristics of children hospitalized with gastrointestinal infections before the COVID-19 pandemic, to the first strict lockdown in 2020 and to the second, less strict lockdown in 2021.
A retrospective review of medical records will be performed, of patients aged 1 month to 5 years admitted with gastroenteritis at the pediatric department at Slagelse Hospital in Denmark over a period from 2017 to 2021.
Full description
Admission patterns among children with non-Covid gastro-intestinal infections before and during the Covid-19 pandemic
This will improve understanding of the indirect effects of the Covid-19 pandemic
HYPOTESES
During the winter-spring months after the lock-down in 2020 fewer children were admitted with gastro-intestinal infections, relative to the winter-spring months of the pre-pandemic years, while more children were admitted during the winter-spring season of 2021 relative to pre-pandemic years.
Children admitted during the winter-spring season of 2021 were more severely ill, and older than children admitted during the prepandemic seasons.
BACKGROUND During the COVID-19 pandemic, admission patterns for infections other than Covid-19 have changed dramatically among children worldwide. [1][2]
During the first lockdown of 2020 a dramatic decline in children admitted with infections other than Covid-19 was reported worldwide. [1] Initially, concerns was expressed that this decline could be due to fear of seeking health care, or other barriers to access health care. For example, children with newly diagnosed diabetes in Germany were reported to present with ketoacidosis more frequently than before the pandemic. [3] [4] However, the main reason is likely to be reduced social contact limiting the spread of many other infections.
Later, reports of delayed epidemics - for example, the expected annual epidemic of respiratory syncytial virus did not occur in the winter of 2021, only to occur later and unexpectedly in the summer. This was first reported in Australia, and later in the Northern hemisphere, including Denmark [5][6].
Particularly admissions due to respiratory infections and later invasive streptococcal infections have been well documented.
Annual epidemics of viral gastrointestinal infections are known to occur in children in the winter and spring months, most caused by rotavirus infections. In the spring of 2021 many Danish paediatricians experienced an unusual surge of children admitted with gastroenteritis, and the general impressioin was that children werre older and more severely dehydrated than during previous seasons.
However, it has not yet been assessed whether gastroenteritis rates were indeed higher in 2021 during the pandemic, compared to the previous years, and whether the admitted children differed from children admitted before the pandemic.
Accordingly, this is what is planned to investigate with the current project.
Hopefully, the project may improve understanding of how well-known and regular epidemics are affected indirectly by the emergence of new diseases - and by the public health measures applied to prevent its spread. This may potentially inform management of future pandemics to reduce the harms, directly as well as indirectly.
Retrospective review of patient files among children admitted with gastrointestinal infections in the paediatric department of Slagelse Hospital, during the spring-winter months (january to june) of three periods:
Participants:
Children aged from >1 months to <5 years with symptoms of gastroenteritis admitted to the paediatric department in Slagelse Hospital
Patient files will be identified in the electronic health record (EPIC) by a search of diagnoses such as "gastroenteritis", "rotavirus", "vomiting", "diarrhea", "dehydration". Each patient file will be evaluated by a doctor, and the child will be included if it is confirmed that the child was admitted with symptoms of gastrointestinal infection.
Data From the identified patient files anonymized data will be retrieved on age, gender, preexisting disease, past history, family type, breastfeeding, nutritional status, estimated degree of dehydration, as well as symptoms and clinical findings on admission, treatment given, duration of admission as well as microbiology and biochemical data.
Handling of data Data will be handles according to GDPR regulations. Anonymized data will be entered into a secured database (RedCAP) and analysed using the statistical package Stata.
Funding The Slagelse hospitals research fund has funded three months of salary for a junior doctor and a medical student to type data and conduct the study
Ethical issues and authorisation: The project has been registered on the research directory of Region Zealand (Regions Sjællands Interne Forskningsfortegnelse, no. REG-087-2021.)
The committee of research ethics of Region Zealand has stated that the study does not need reaserch ethical approval according to Danish Law, as it only involves retrieval of data from hospital files.
Regions Zealand has approved that anonymized data is collected from patient files without consent from the parents (Ref nr: R-21041034)
