Evolution of Hospitalisation Due to Stroke in Italy Before and After the Outbreak of the COVID-19 Epidemic: A...

Background/Objectives: Stroke is a leading cause of mortality and disability worldwide, ranking as the second most common cause of death and the third in disability-adjusted life-years lost. Ischaemic stroke, which constitutes the majority of cases, poses significant public health and economic challenges. This study evaluates trends in ischaemic stroke hospitalisations in Italy from 2008 to 2022, focusing on differences before and after the COVID-19 pandemic. Methods: We analysed ischaemic stroke hospitalisations among individuals admitted through emergency services using Italian hospital discharge records from 2008 to 2022. Poisson Inverse Gaussian regression was employed to assess hospitalisation trends, accounting for age, sex, and geographic variations. Results: Among 1,689,844 ischaemic stroke hospitalisations, there was a marked age-related increase, particularly among individuals aged 74 and older, with males consistently showing higher rates. Hospitalisation trends demonstrated a 20% reduction over 15 years, suggesting improvements in stroke prevention and treatment. However, there was a slight increase in rates during the COVID-19 period, despite the overall declining trend, highlighting the potential healthcare challenges experienced during the pandemic. Multivariable analysis confirmed age and male sex as significant risk factors. Conclusions: This study underscores the age-related increase in stroke hospitalisation rates, emphasising the need for targeted prevention strategies for elderly populations. The overall reduction in stroke hospitalisation rates reflects advancements made in healthcare, although the impact of COVID-19 on access to stroke care is evident. Future policies must address the pandemic's effects on stroke care continuity and prioritise interventions tailored to age and sex.
