We aimed to identify non\u2010infectious paediatric conditions for which the incidence of hospital admissions increased during the introduction and alleviation of NPIs in 2020.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We examined anonymous hospitalisation data from Perth's sole tertiary paediatric hospital (Jan 2015\u2013Dec 2020), according to pre\u2010defined age groups (0\u20134\u2009years, 5\u20139\u2009years, 10\u201316\u2009years and 0\u201316). We identified the most frequent non\u2010infectious diagnoses in these age groups over five different NPI periods. We quantified the impact of NPIs on admissions for the most frequent diagnosis groups (perinatal disorders, mental disorders) using interrupted time series (ITS) analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Following implementation of NPIs, admission rates for perinatal disorders amongst 0\u20134\u2009year\u2010olds increased by 18% (IRR\u2009=\u20091.18 [95% CI: 1.04\u20131.35]). ITS analysis revealed non\u2010significant changes in admissions for mental disorders in 10\u201316\u2009year\u2010olds (IRR\u2009=\u20090.91 [95% CI: 0.79\u20131.06]).

Amongst mental disorders more generally, it is possible that admission rates in 2020 may have been greater had COVID\u201019 associated NPIs not disrupted pre\u2010pandemic trends. These findings aid our understanding of social factors mediating paediatric disease and may improve healthcare delivery in a post\u2010pandemic era.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jpc.70111","type":"journal-article","created":{"date-parts":[[2025,7,9]],"date-time":"2025-07-09T15:25:27Z","timestamp":1752074727000},"page":"1460-1470","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Unintended Impact of <scp>COVID<\/scp>\u201019 Associated Non\u2010Pharmaceutical Interventions on Paediatric Hospital Admissions: An Interrupted Time Series Analysis"],"prefix":"10.1111","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3584-4193","authenticated-orcid":false,"given":"Mitchell T.
