COVID-19 pandemic altered timing of psychiatric admissions across three European countries

This retrospective multicenter observational study analyzed psychiatric hospitalizations in Austria, Germany, and Italy from 2017 to 2020 to examine whether the COVID-19 pandemic produced diagnosis-specific and cross-nationally reproducible alterations in admissions. The study compared admission patterns during the pandemic year (2020) with pre-pandemic years (2017-2019).

The main finding was that the pandemic did not induce diagnosis-specific increases in acute psychiatric admissions. However, it substantially altered their temporal organization. In Austria and Germany, 2020 was associated with a marked temporal distortion in admission patterns compared with previous years (Week × Year interaction, p < 0.001). Italy showed a different pattern, though specific statistical details were not reported. Absolute admission numbers and effect sizes were not provided.

Safety and tolerability data were not reported. The study has several limitations: it is observational and retrospective, which prevents establishing causation between the pandemic and admission changes. It is limited to three European countries, limiting generalizability. Mechanisms behind the observed patterns were not explored. Funding and conflicts of interest were not reported.

For practice, the differences across countries highlight how healthcare structure—particularly the integration of territorial and inpatient services—modulates system resilience under crisis conditions. Clinicians should interpret these findings as descriptive patterns rather than evidence of causal pandemic effects on psychiatric morbidity.
